Description
Technical Field
[0001] This utility model belongs to the technical field of catenary cable arrangement, and specifically relates to a catenary cable anchoring and rotation device. Background Technology
[0002] The process of anchoring the catenary cable involves placing the catenary cable on the contact wire post, then pulling the catenary cable using a pulley system to adjust its tension on the contact wire post. After adjusting the tension, the connection between the catenary cable and the contact wire post is reinforced to secure the catenary cable.
[0003] However, in the actual process of anchoring the catenary, one end of the catenary is installed on the pulley block, and the catenary is installed on multiple contact wire posts. In the process of adjusting the tension of the catenary, multiple people are needed to assist in tightening the pulley block. Utility Model Content
[0004] In order to solve the above-mentioned problems in the prior art, namely the inconvenience of adjusting the catenary during the anchoring process, this utility model provides a catenary anchoring rotary device.
[0005] This application discloses a catenary anchoring and slewing device, which adopts the following technical solution:
[0006] A load-bearing cable anchoring and slewing device includes a base fixedly connected to the body of a railcar, an arrangement plate mounted on the base, a winch fixedly connected to the arrangement plate, and an adjustment assembly mounted on the arrangement plate.
[0007] The adjustment assembly includes a support arm connected to the arrangement plate, the upper end of which is arranged at the same height as the top of the contact wire column.
[0008] By adopting the above technical solution, one end of the catenary cable is connected to one end of the rope on the winch. The connection can be made using a hook-and-loop method. As the railcar moves forward, the catenary cable is pulled. When the tension of the catenary cable needs to be adjusted, the winch can be activated to assist in winding and unwinding the cable. This eliminates the need to adjust the position of the railcar when adjusting the tension, and makes it easier to adjust the tension of the catenary cable on multiple contact wire posts. Specifically, when the catenary cable is connected to the winch, it overlaps the support arm. The top of the support arm maintains the catenary cable's height on the contact wire post, preventing it from bending downwards on the post and affecting the determination of its tension.
[0009] Optionally, a bracket is fixedly connected to the end of the support arm;
[0010] The bracket is equipped with a horizontally arranged top pulley that is rotatably connected to the bracket.
[0011] By adopting the above technical solution, the top pulley facilitates the sliding of the load-bearing cable on the support arm.
[0012] Optionally, an auxiliary frame is fixedly connected to the bracket, and two auxiliary pulleys that are rotatably connected to the auxiliary frame are installed on the auxiliary frame. The auxiliary pulleys are arranged longitudinally and are located on both sides of the top pulley.
[0013] By adopting the above technical solution, the auxiliary pulley can block the catenary when it bends laterally and guide it to slide, effectively installing the catenary on the support arm and preventing it from falling off.
[0014] Optionally, the auxiliary frame includes two first partitions and a second partition arranged parallel to the first partitions; the auxiliary pulley is arranged between the second partition and the two first partitions; the second partition is arranged on the upper side of the top pulley; the top pulley, the two auxiliary pulleys and the second plate form a ring.
[0015] By adopting the above technical solution, when the catenary is arranged, the catenary overlaps on the top pulley and passes between the top pulley and the second partition plate. The catenary is restricted by the top pulley, auxiliary pulley and the second partition plate to prevent the catenary from falling off.
[0016] Optionally, the base includes a rotating sleeve with an opening at the upper end; a rotating seat is provided between the base and the arrangement plate;
[0017] The rotating seat includes a rotating block inserted into and rotatably connected to the rotating sleeve, and the arrangement plate is fixedly connected to the upper side of the rotating block. When the rotating block rotates, it drives the arrangement plate to rotate.
[0018] By adopting the above technical solution, setting a rotating seat, and adjusting the arrangement angle of the support arm, the top distance of the two support arms can be adjusted according to the distance between the contact wire columns on both sides of the track, thereby adjusting the tension of the catenary cable arrangement on the contact wire columns with different spacing.
[0019] Optionally, the support arm is hinged to the arrangement plate, and a telescopic cylinder is installed on the arrangement plate. The flipping direction of the support arm and the arrangement plate is aligned with the wire feeding and retracting direction of the winch.
[0020] The bottom of the telescopic cylinder is hinged to the arrangement plate, the telescopic cylinder is arranged between the support arm and the winch, and the piston rod of the telescopic cylinder is hinged to the arm body of the support arm.
[0021] By adopting the above technical solution, the extension and retraction of the telescopic cylinder can be used to adjust the angle of the outrigger on the arrangement plate, thereby adjusting the arrangement height of the other end of the outrigger.
[0022] Optionally, the bracket includes a support plate, which is fixedly connected to the end of the support arm, and two ear plates are vertically fixedly connected to the support plate. The two ear plates are arranged in parallel, and the top pulley is rotatably connected between the two ear plates.
[0023] Optionally, the base also includes a fixing cylinder, which is fixedly connected to the body of the railcar. A fixing plate is fixedly connected to the upper side of the fixing cylinder. The fixing plate is horizontally arranged, and a connecting plate is fixedly connected to the fixing plate. The connecting plate is horizontally arranged and fits against the fixing plate.
[0024] The rotating sleeve is fixedly connected to the upper side of the connecting plate.
[0025] The beneficial effects of this utility model are:
[0026] (1) The catenary is assisted in being wound and unwound by a winch. When adjusting the tension of the catenary, it is not necessary to adjust the position of the railcar back and forth. Furthermore, it is easier to adjust the tension of the catenary on multiple catenary columns.
[0027] (2) The top pulley, auxiliary pulley and second plate are used to restrict the catenary and prevent it from falling off.
[0028] (3) By setting a rotating seat and adjusting the arrangement angle of the support arm, the top distance of the two support arms can be adjusted according to the distance between the contact wire columns on both sides of the track, thereby adjusting the tension of the catenary cable arrangement on the contact wire columns with different distances.
[0029] (4) By extending and retracting the telescopic cylinder, the angle of the outrigger on the arrangement plate is adjusted, thereby adjusting the arrangement height of the other end of the outrigger. Attached Figure Description
