    DESCRIPTION

    Equipment for lifting gutter covers and cable positioning and associated procedure.
     5 OBJECT OF THE INVENTION

    The scope of the present invention is framed within the railway infrastructure sector, focusing particularly on the field of equipment intended for laying electrical wiring, and more specifically those intended to be deposited in gutters.

    More in particular, the object of the invention is focused on equipment whose purpose is to provide an autonomous machine for the collection and deposition inside the cable duct of the railway infrastructure, which is provided with means 15 to perform at the same time the tasks of lifting the covers, cleaning the gutter and returning to the gutter covers.
    BACKGROUND OF THE INVENTION
     twenty
    At present, the completion of the process intended to cover the present invention consists of the following phases:

    Recognized the gutter in the trace, the first task that operators must do is the removal of the covers, a process that is currently done manually causing a decrease in production rate due to the fatigue of the operators themselves.

    In addition, to prevent the interior of the gutter from becoming too dirty due to remaining uncovered for a long period of time, normally such cleaning is only performed in a stretch of X kilometers, said section being low enough not to delay the process carried out. finished.

    Another of the great disadvantages of the removal of the lid, is the need for occupation of the trace by the material removed. This fact means that the rest of the machinery is hindered when executing the rest of the works that are being carried out in the trace.

    Once the covers have been removed, the gutter is cleaned to remove the dirt inside it in the course of time that it has remained open.
     40
    This point is essential, since when the channel gets dirty it causes the cable to deteriorate, resulting in a possible electrical conduction failure. This deterioration would be much greater if the dragging of the cables occurs in the work of laying due to the aggressive friction suffered between the materials.
     Four. Five Once the interior is cleaned, the wiring is laid and the cables are laid.

    Once the gutters are closed, the operator must advance another few kilometers by simply performing the task of lifting the covers. Then the cleaning and laying operations will be repeated. fifty

    This process, described in summary form, currently requires long periods of execution with abundant delays due to the fatigue of the personnel in charge of carrying out each of the phases.
    The main disadvantages of the previous process is that it cannot be executed in parallel, that is, in the first work the opening of the covers is needed, to try to make the process quick, then return to the starting point and tends the cable. The last phase of the process would involve returning to the starting point for the closing of the previously opened covers. 5

    In addition to the delay that may be the fact of being moving forward and backward at different points of the work, we must add to the process the dirt that the gutter can accumulate by being with the lid lifted for a prolonged time in an area where works are being executed of maintenance or installation, as well as of the damages suffered by the material.
    DESCRIPTION OF THE INVENTION

    To solve the problem described, the equipment of the invention is configured as an autonomous machine 15 intended for the collection and deposition of wiring inside the gutter, preferably previously launched by an annexed equipment that is not part of the present invention, seeking , at the same time, the lifting of the covers and the cleaning of the gutter.

    To this end, said machine essentially comprises conveniently incorporated in a carrier system, an electrical wiring collection and feeding system, a structural system responsible for lifting and closing gutter covers, a cleaning system, an ejection system for covers, and a motor system in charge of supplying the necessary energy to transfer to the machine autonomously.
     25
    It should be noted that, preferably, the machine has no direction in order to limit the rotation of the same, so that it follows the direction of the self-driving raceway guided by the same set of gutter, although, preferably, the driving wheels are mounted on a sliding system transversely with respect to the chassis that allows to modify the position of the driving system and therefore of the wheels to overcome the obstacles encountered on the track, such as concrete boxes or blocks.

    For the installation of the electro-motor system, it has been estimated that it should only transport the machine's own weight, since it does not carry additional loads. Thus, the mechanical energy provided by the main motor is converted into hydraulic energy in charge of moving the motor-reducer that transmits the torque to the driving wheels.

    For its part, the electrical installation is preferably carried out at 12 V which are given by a battery that feeds the different accessories of the maneuver and power circuit such as relays, fuses, alternator and fan. In addition, since the objective of the machine is to be autonomous, the oil and battery reservoir belonging to the hydraulic and electrical system respectively has been installed in the machine's own supporting structure.

    To make the machine more versatile, it is suitable for changing the direction by acting directly on the lever that regulates the hydraulic system oil. And, additionally, 45 also allows the regulation of the speed of advance of the machine to adapt it to the performance of the work required.

    As for the above-mentioned functional and structural systems contemplated by the machine that makes up the equipment of the invention, it should be noted that they have the following characteristics:

    - Support system: composed of chassis that provides the system with sufficient rigidity and stability to carry out the work for which it is intended. This chassis has two
    supports, the first and main provided by the driving wheels and the second is provided by two other guide wheels, metallic in this case, which are dragged by the driving wheels themselves.

    In the chassis the necessary supports and fasteners are arranged to locate the electro-5 motor and hydraulic system, preferably housed in a fence or central frame. One of the peculiarities that the chassis of the supporting system has is that the height can be regulated by means of a system of regulation of the same to calibrate the lifting system of covers, as it is convenient. Another of the advantages provided by the regulation is that of being able to modify the height of the chassis with respect to the ground depending on the type of driving wheels that are mounted and the type of terrain on which it is working.

    - Wiring collection and deposition system: composed of auxiliary structures configured to receive electrical wiring and guide it into the gutter. For this, these auxiliary structures have rollers and separators that serve as support and guide for the cables, to prevent them from coming into contact, with the aim of avoiding possible friction that would damage the quality of the cable. The main feature of these rollers is that they are motorized in a way that facilitates the work of wiring, preventing damage to the material due to improper execution.
     twenty
    - System for lifting and closing gutter covers: responsible for lifting and closing the gutter covers to proceed with the deposition of electrical wiring into the gutter. The movement of the cover is based on a wave movement, in which the cover of the gutter performs a vertical displacement and subsequently a horizontal displacement of the machine below the imaginary line that joins the gutter covers. 25 For this purpose, this lifting and closing system is composed of a sliding roller structure that, as a treadmill, has an initial ascending section that lifts the covers, a central section elevated horizontally, which keeps the covers elevated allowing cleaning and insertion of the cables, and a final descending section, to re-deposit the covers and close the gutter. With this, the rollers of each section allow the machine 30 to move without causing any damage to the covers. In addition, in the final descending section the existence of lateral guides is provided that will prevent the cover from deflecting and falling to the ground or not being placed in its correct position on the gutter.

    - Cover ejection system: in order to leave the covers on either side 35 of the gutter, depending on the needs of the client's execution or requirements, the equipment machine is optionally equipped with an articulated substructure, coupled to the chassis of the supporting system, after the horizontal section of the above-mentioned roller structure, so that, instead of re-depositing the covers on the gutter, it allows them to be deposited on the ground, without it suffering any type of damage. 40

    - Cleaning system: formed by the necessary elements to clean the gutter, also contemplating a fitting that allows the coupling between the body of the gutter and the lid.
     Four. Five
    Specifically, said cleaning elements are preferably formed by a blade located in the front part, so that it acts first, being in charge of removing the thicker material, to prevent the more granulometry lands from entering inside. of the gutter for not being able to be removed by the rest of the cleaning elements.
     fifty
    Said cleaning elements further comprise, a set of brushes will have as components a first motorized brush, arranged next to the blade, responsible for cleaning the gutter before proceeding with its lifting, and fixed side brushes, arranged in the central area of the machine, under the initial section of the roller system that
    Lift the covers, being in charge of cleaning the rail where the cover of the gutter rests.

    The last element that forms the cleaning system is a suction system, responsible for removing all the dirt accumulated inside the gutter once the covers are lifted. 5

    Finally, as for the electro-motor system, you can incorporate a main motor of 18 hp, responsible for providing the pumps with sufficient mechanical energy to activate the hydraulic system.
     10
    A second aspect of the present invention relates to the procedure of positioning of railway track cables in a gutter with an equipment such as that described, and by means of which, in a single task, the lifting of the gutter cover, cleaning is contemplated. of the gutter, collection, guidance and deposition of the electrical wiring and the closing of the gutter by means of the deposition of the gutter cover in its initial position or, optionally, the deposition of the gutter cover to one side of the trace .

    Thus, the main advantages of the gutter cover lifting and cable positioning equipment are the following:
     twenty
    • Full coordination is achieved between the equipment for cable launching and the machine responsible for receiving and depositing wiring.
    • You get a perfect guidance of electrical wiring inside the gutter.
    • The lifting of the cover, collecting, guiding and laying the electrical wiring, cleaning the inside of the gutter and closing the gutter is carried out in a single task by means of the deposition of the gutter cover in its initial position.
    • The option of leaving the gutter cover next to the trace is possible, depending on the execution needs.
    • The interior of the gutter is cleaned before closing the cover and laying the wiring. 30
    • The covers do not suffer any damage in the process, the channel being perfectly closed to prevent dirt from entering.
    • The operations of wiring collection, cover movement and cable deposition are done in a coordinated manner so that the productivity of the process is increased.
    • The hydraulic, motor, and electrical system are installed in the machine in a compact way 35 making it a more compact, safe and easy to maintain machine.
    • No work requires labor by any operator making lifting and cleaning work safer by reducing the likelihood of an accident at work.
    • The machine responsible for lifting and closing covers is autonomous so that it can execute the operations for which it has been designed independently of the rest of the civil machinery.
    Ideally, the lifting equipment described is suitable for working in a coordinated manner with a cable launching equipment from the railway to the gutter bypassing the catenary.

     30 PREFERRED EMBODIMENT OF THE INVENTION

    In view of the aforementioned figures, according to the numbering adopted, a non-limiting example of the equipment constituting the object of this invention can be observed.
     35
    Thus, as seen in Figures 1 and 2, the equipment in question is configured as an autonomous machine (1) that essentially comprises a supporting system, consisting of a chassis (2) with wheels (3, 4) designed to move over the channel in which the wiring is intended to be deposited, and in which at least one cable collection and deposition system (5), a lifting system (6) and closing the covers, a system are coupled of cleaning (7) 40 of the gutter and an electro-motor and hydraulic system (8) to ensure its autonomous movement and operate said systems.

    Entering more details, the chassis (2) presents a central frame (21), to house the electro-motor system, whose components will be detailed below, and paths 45 extensions, a previous extension (22) in which it is contemplated a pair of drive wheels (3), preferably pneumatic, and another rear extension (23) in which a pair of drive wheels (4), preferably metal, is contemplated, also existing at least one point of said chassis ( 2) a height adjustment mechanism (24), which allows calibrating the lifting system (6) and closing the covers, and modifying the height of the chassis (2) 50 with respect to the ground.

    The wiring collection and deposition system (5) comprises a series of auxiliary structures (51, 52) equipped with rollers and separators (53) that serve as support and guide for
    the cables. More specifically, a first pair of structures (51) with motorized rollers linked to each other by belt is contemplated, on the lateral part of the anterior extension (22) of the chassis (2), at least one central structure (52) , also with motorized rollers, arranged on the side of the frame (21) and at least one spacer (53) under the central area of the lifting system (6). Figure 1 shows, 5 by a thick dashed line, referred to as (50), the wiring path through the auxiliary structures (51, 52) and separators (53) of this collection and deposition system wiring (5).

    The lifting system (6) and closing of covers comprises a sliding structure (61) of 10 multiple rollers (62) arranged transversely and parallel at equidistant intervals between two side profiles (63), acting as a treadmill, said profiles being angled sides (63) so that the sliding structure (61) has an initial ascending section (a) a horizontal central section (b) and a final descending section (c) which, with the movement of the machine (1), respectively lifts the covers, keeps them elevated and 15 puts them back on the gutter, working in the same way when the machine moves in the opposite direction, since the drive system allows its movement in both directions by means of the actuation of a lever (not shown) ) provided for this purpose in the hydraulic system.
     twenty
    Preferably, lateral guides (64) are provided in the final descending section (c) to prevent the cover from deflecting.

    Also additionally, the preferred embodiment of the machine (1) contemplates an ejection system (9) of covers that allows them to be left on one side of the gutter, which comprises an articulated substructure (91), coupled at the end of the subsequent extension (23) of the chassis (2), after the horizontal section (b) of the roller structure (61), so that the covers, instead of descending again down the final descending section (c) of said structure, are ejected laterally and deposited on one side of the gutter.
     30
    The cleaning system (7) comprises various elements for cleaning the gutter, before lifting the lid, for cleaning the rail where the lid is supported and for cleaning the dirt inside.

    In particular, said cleaning elements are preferably formed by a blade (71) located under the anterior extension (22) of the chassis (2), a first motorized brush (72), arranged next to the blade (71) , fixed side brushes (73), arranged in the central area of the machine under the initial ascending section (a) of the sliding structure (61), and a suction system (74) with a suction mouth (75) located under the horizontal central section (b) of said sliding structure (61). 40

    Finally, according to Figure 7, it can be seen how the electro-motor and hydraulic system (8), comprises a main motor (81), responsible for providing the pumps (82, 83) with sufficient mechanical energy to activate the hydraulic system.
     Four. Five
    For this, the main pump outlet (82) is connected to a hydraulic motor (84) through a pressure distributor (85), in charge of allowing the machine to move in one direction or another, for which the The energy of this hydraulic motor (84) is again transformed into mechanical energy by means of a motor-reducer (86) which, as shown in Figure 4, drives the driving wheels (3) in the selected direction of advance. fifty

    To put into operation the main engine (81) the machine has an electrical system (87) or battery that supplies said motor and other components such as the cleaning system (7), work lights and emergency stop ( items not
    represented) .. In addition, to make the job safer, there are three emergency stops in charge of cutting off the power supply of the electrical system (87) of the machine (1), in order to solve any dangerous situation detected. Additionally, a generator has been installed to be able to feed different accessories,
     5
    For its part, the hydraulic system is formed by a closed circuit comprising the two pumps (82, 83) of unidirectional flow. The main pressure line crosses a first pressure distributor (851) which is responsible for selecting the direction of rotation of the driving wheels (3), as already explained. The outlet of this distributor (85) crosses the hydraulic motor (84) responsible for converting fluid energy into mechanical energy 10 on the shaft (31), which moves directly to the driving wheels (3), by means of the motor-reducer ( 86); at the exit of this motor (86), a fourth motor (88) is contemplated that drives the motorized brush (72) of the cleaning system (7). On return to return, the main pressure line passes through a cooler (89), consisting of an oil / air exchanger, responsible for maintaining the temperature of the hydraulic oil within an optimum range. fifteen

    The secondary pressure line feeds the suction system (74), the pressure is provided by the second pump (83), coupled to the main pump (82), through a second distributor (852). The oil in the circuit is supplied by a tank (80) provided for this purpose in the machine.
     twenty
    To avoid problems of pressure losses, the hydraulic circuit is as compact as possible, reducing the lengths and changes of direction of the hydraulic hoses.

    Additionally, there is an emergency stop solenoid valve that (not shown) reads the oil pressure at the pump outlet and, if it exceeds the expected pressure, sends a signal to the electrical circuit that will cause the of the flow return to the hydraulic tank (80) thus reducing the pressure of the circuit, so that it does not work at any time outside the working conditions.

    With all this, the equipment allows to carry out the cable positioning procedure 30 in the gutter comprising, in a single task, the following steps:

    - cleaning and removal of coarse material on the surface of the gutter, before lifting the lid, using the blade (71) and the brush (72) provided in the cleaning system (7),
     35
    - lifting the gutter cover, and lifting it, by means of the sliding structure (61) based on rollers (62) provided in the lifting system (6),
