Description
Technical Field
[0001] The utility model relates to the technical field of railway transportation equipment maintenance tools, in particular to an auxiliary device for maintenance of a coupler of an open wagon. Background Art
[0002] C70 general-purpose open wagons are primarily used to load bulk cargoes like coal, ore, and steel that are weatherproof. However, during daily use, the couplers on these wagons can easily disengage due to buffer rebound, preventing the coupler from aligning properly. This prevents manual resetting of the buffers, preventing the coupler from resetting and causing vehicle failure. Consequently, railway operators often resort to removing the wagons from the loading marshaling unit and returning them to the depot for temporary repairs, often without the necessary technical expertise. This increases operational complexity and reduces vehicle efficiency. Utility Model Content
[0003] In order to solve the above technical problems, the utility model provides an auxiliary device for repairing couplers of open wagons.
[0004] The technical solution of the present utility model is achieved as follows:
[0005] A gondola coupler maintenance aid includes a trolley, a coupler shelf, a hanging chain, and a jack holder. The coupler shelf is mounted on the trolley. Two hanging chains are provided, and the tail ends of both hanging chains are connected to the trolley. The jack holder is mounted on the trolley and is used to place a jack. The jack holder is located on the rear side of the coupler shelf. The trolley allows the maintenance aid to be easily pushed to the side of a universal gondola coupler that needs maintenance, facilitating maintenance personnel to quickly move and position between different vehicles, thereby improving work efficiency. The coupler shelf provides a stable platform for placing and supporting the coupler to be repaired, ensuring that the coupler can be stably placed on the trolley during the maintenance process. The hanging chain is used to connect to the universal gondola and secure the trolley when the jack is used to push the coupler forward, thereby maintaining the stability of the maintenance aid. The jack holder is used to place and secure the jack, and the coupler is reset by pushing the jack forward.
[0006] Furthermore, the jack holder includes a base plate, and the upper surface of the base plate is provided with a groove for placing the jack. By providing the base plate and the groove for placing the jack, the jack is ensured to be stably placed in the jack holder, which is convenient for operation and use.
[0007] Further, a support plate is provided in the groove, a baffle is vertically provided at the tail end of the support plate, inner rotating clamping blocks are provided on both sides of the seat plate, outer top blocks are provided on both sides of the seat plate, and the front end of the outer top block is connected to the front end of the support plate. The outer top block drives the two inner rotating clamping blocks to clamp the jack from both sides by moving backward. By providing the support plate to support the bottom of the jack, the baffle prevents the jack from slipping out of the jack seat during use. By the backward movement of the outer top block, the two inner rotating clamping blocks are driven to clamp the jack from both sides, realizing the fixation of the jack, so that the jack can be stably fixed in the jack seat during use.
[0008] Further, the front ends of the two outer top blocks are connected by a synchronous plate, and the synchronous plate is fixedly connected to the front end of the support plate. By providing the synchronous plate to connect the front ends of the two outer top blocks, it is ensured that the two outer top blocks can move synchronously, guaranteeing that the two inner rotating clamping blocks can clamp the jack from both sides simultaneously, realizing a stable clamping effect.
[0009] Further, the inner rotating clamping block includes a plate body and a block body. The plate body has a "C" - shaped structure. The block body is rotatably installed at the top end of the plate body, and the bottom end of the plate body is rotatably installed on the side surface of the seat plate, and the block body is located above the side of the seat plate. By the rotation of the plate body relative to the seat plate and the rotation of the block body relative to the plate body, the inner rotating clamping block can be rotated and adjusted as needed to better clamp or release the jack.
[0010] Further, the top end height of the block body is greater than the top end height of the plate body. The side surface of the block body facing the groove is an inclined surface with the bottom end inclined outward, and a stop bar supporting the top end of the plate body is provided on the block body. By setting the top end height of the block body greater than the top end height of the plate body and the stop bar, it is prevented that the block body rotates excessively, ensuring that the inclined surface of the block body clamps on both sides of the jack, realizing a fast and stable clamping effect while ensuring the stability of clamping.
[0011] Further, a horizontal axis is fixedly installed at the bottom end of the front side surface of the plate body. The horizontal axis is rotatably installed on the side surface of the seat plate. A vertical axis is installed at the front end of the horizontal axis. The rear end surface of the outer top block has an inclined surface for externally pushing the vertical axis. When the outer top block moves backward, the inclined surface of the outer top block externally pushes the vertical axis, causing the horizontal axis and the plate body to rotate around its bottom end, thereby driving the inner rotating clamping block to clamp the jack from both sides, improving the convenience and efficiency of operation.
[0012] Further, a strip - shaped groove is formed on the surface of the outer top block, and a longitudinally distributed guide rod is slidably arranged in the strip - shaped groove, and the guide rod is installed on the side surface of the seat plate. By providing the guide rod in the strip - shaped groove of the outer top block, longitudinal sliding guidance is provided, ensuring that the outer top block maintains a stable trajectory during movement and preventing it from shifting or shaking.
[0013] The utility model has the following beneficial effects:
[0014] 1. Through the backward displacement of the outer top block, the two inner rotating clamps can clamp the jack from both sides synchronously, ensuring the stability and safety of the jack during maintenance and improving maintenance efficiency.
[0015] 2. By adjusting the position and angle of the inner rotating clamp, stable clamping of jacks of different sizes and shapes can be achieved.
[0016] 3. The strip grooves on the surface of the outer top block and the sliding guide rod design make the movement of the outer top block more stable and easy to control. The use of the synchronization plate ensures that the two outer top blocks can move synchronously, further simplifying the operation process. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] like Figures 1 to 4As shown, an open car coupler maintenance auxiliary device includes a trolley 1, a coupler shelf 2, a hanging chain 3 and a jack holder 4. The coupler shelf 2 is installed on the trolley 1, two hanging chains 3 are provided, and the tail ends of the two hanging chains 3 are connected to the trolley 1. The jack holder 4 is installed on the trolley 1 for placing the jack, and the jack holder 4 is located on the rear side of the coupler shelf 2. The trolley 1 serves as a mobile base for the maintenance assistant, has a stable structure and sufficient carrying capacity, and allows maintenance personnel to push the maintenance assistant to the universal open car coupler that needs maintenance, realizing rapid movement and precise positioning between different vehicles, improving the efficiency and convenience of maintenance work, and reducing the labor intensity of manual handling. The coupler shelf 2 provides a stable and flat shelf surface for the coupler to be repaired, avoiding maintenance problems caused by the shaking of the coupler, and ensuring the stability and safety of the maintenance process. The hanging chain 3 fixes the trolley 1 by connecting it to the universal open car, ensuring that the trolley 1 can remain stable when the jack pushes the coupler forward, thereby improving the safety of the maintenance work. The jack holder 4 provides a placement and fixing area for the jack, ensuring that the jack can be fixed on the jack holder 4 during the maintenance process, thereby ensuring the safety of the jack during use.
[0024] The jack base 4 includes a base plate 5, and a groove 6 for placing the jack is provided on the upper surface of the base plate 5. The base plate 5 provides support for the jack, and the groove 6 provides a stable placement space for the jack, ensuring the safety and stability of the jack on the jack base 4.
[0025] A support plate 7 is provided within the groove 6, with a baffle 8 perpendicularly disposed at the rear end of the support plate 7. Inwardly rotating clamping blocks 9 are provided on either side of the base plate 5, and outer push blocks 10 are provided on either side of the base plate 5. The front ends of the outer push blocks 10 are connected to the front ends of the support plate 7. The outer push blocks 10 drive the two inwardly rotating clamping blocks 9 to clamp the jack from both sides by moving backward. The support plate 7 supports the bottom of the jack, and the baffle 8 prevents the jack from falling out of the jack holder 4 during use. The outer push block 10 moves backward, driving the two inwardly rotating clamping blocks 9 to rotate inward from both sides until they clamp the jack, ensuring the stability and safety of the jack on the jack holder 4 and improving maintenance efficiency.
[0026] The front ends of the two outer top blocks 10 are connected by a synchronization plate 11, and the synchronization plate 11 is fixedly connected to the front end of the support plate 7. The design of the synchronization plate 11 enables the two outer top blocks 10 to move synchronously, ensuring that the two inner rotating clamps 9 can simultaneously rotate inward from both sides to clamp the jack.
[0027] The inner rotating clamping block 9 includes a plate body 9.1 and a block body 9.2. The plate body 9.1 has a "C" - shaped structure. The block body 9.2 is rotatably installed at the top end of the plate body 9.1. The bottom end of the plate body 9.1 is rotatably installed on the side surface of the seat plate 5, and the block body 9.2 is located above the side of the seat plate 5. The plate body 9.1 has a "C" - shaped structure, which enables the plate body 9.1 to have sufficient strength and stability. The bottom end of the plate body 9.1 is rotatably installed on the side surface of the seat plate 5, ensuring that the plate body 9.1 can rotate around its bottom end on the seat plate 5. The block body 9.2 is rotatably installed at the top end of the plate body 9.1, ensuring that the jack can be effectively clamped. The block body 9.2 is located above the side of the seat plate 5. When the plate body 9.1 rotates, the block body 9.2 will clamp the jack from the side. Through the plate body 9.1 and the block body 9.2, the inner rotating clamping block 9 can rotate and adjust as needed, achieving a more flexible and stable clamping effect.
[0028] The top height of the block body 9.2 is greater than the top height of the plate body 9.1. One side of the block body 9.2 facing the groove 6 is an inclined surface with the bottom end inclined outward, and a stop rod 12 is provided on the block body 9.2 to support the top end of the plate body 9.1. The top height of the block body 9.2 being greater than the top height of the plate body 9.1 enables the block body 9.2 to better clamp the jack from above during rotation. One side of the block body 9.2 facing the groove 6 is designed as an inclined surface with the bottom end inclined outward, which is beneficial for the block body 9.2 to gradually contact and clamp the jack during rotation, ensuring the smoothness of the clamping process and the uniform distribution of the clamping force. The stop rod 12 is used to limit the movement range of the block body 9.2 when the block body 9.2 rotates, avoiding excessive rotation of the block body 9.2 and providing a more stable and safe clamping effect for the jack.
[0029] A horizontal shaft 13 is fixedly installed at the bottom end of the front side of the plate body 9.1. The horizontal shaft 13 is rotatably installed on the side surface of the seat plate 5. A vertical shaft 14 is installed at the front end of the horizontal shaft 13. The rear end face of the outer top block 10 has an inclined surface for pushing the vertical shaft 14 outward. A rotating shaft is rotationally connected to the outside of the horizontal shaft 13. The bottom of the horizontal shaft 13 is fixedly connected to a U - shaped block. The U - shaped block is fixedly connected to the vertical shaft 14 and the plate body 9.1. When the outer top block 10 moves backward, the inclined surface of the outer top block 10 will push the vertical shaft 14 outward, causing the horizontal shaft 13 to rotate within the rotating shaft, driving the plate body 9.1 and the block body 9.2 to rotate, and driving the inner rotating clamping block 9 to clamp the jack from both sides, improving the maintenance efficiency.
[0030] A strip - shaped groove 15 is formed on the surface of the outer top block 10. A guiding rod 16 distributed longitudinally is slidably arranged in the strip - shaped groove 15, and the guiding rod 16 is installed on the side surface of the seat plate 5. The guiding rod 16 arranged in the strip - shaped groove 15 of the outer top block 10 provides longitudinal sliding guidance, ensuring the stability of the outer top block 10 during movement and preventing deviation and shaking.
[0031] Before the maintenance work, push the trolley 1 to the side of the open car coupler that needs to be repaired, connect the trolley 1 to the open car with the hanging chain 3, place the coupler to be repaired on the coupler shelf 2, place the hydraulic jack in the groove 6 of the jack seat 4, and make the bottom of the hydraulic jack contact with the support plate 7 and the tail contact with the baffle 8. When the hydraulic jack pushes the coupler forward, it drives the baffle 8 to move backward, so that the support plate 7 drives the outer push block 10 to move backward. The outer top block 10 is synchronously displaced backward by the synchronization plate 11. When the inclined surface of the outer top block 10 contacts the longitudinal axis 14, it will push the longitudinal axis 14 outward through the inclined surface, driving the transverse axis 13 and the plate body 9.1 to rotate. The block 9.2 at the upper end of the plate body 9.1 will move from both sides to the center as the plate body 9.1 rotates, so that the inclined surfaces of the two blocks 9.2 clamp the hydraulic jack from both sides. After the clamping is completed, the hydraulic jack pushes the coupler forward to reset the coupler. After the maintenance is completed, the hydraulic jack retracts, driving the baffle 8 to move forward, so that the support plate 7 drives the outer top block 10 to move forward. The inclined surfaces of the two outer top blocks 10 no longer push the longitudinal axis 14 outward, and the transverse axis 13 and the plate body 9.1 rotate in the opposite direction. The inner rotating clamp 9 releases its clamping of the hydraulic jack, the jack is removed, the hanging chain 3 is disassembled, and the cart 1 is pushed back to its original position, completing the maintenance work.
[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
