Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides a rotating maintenance platform for close-fitting hooks. Its basic components mainly include four sets of support plates 101 with rectangular cross-sections, forming a support structure 100. These are welded to a factory iron plate or placed on the ground. The bearing surface is formed on the top of the support plates 101, and a base 102 is provided at the bottom of the support plates 101. Two sets of symmetrical reinforcing ribs 103 are provided on the outer wall of the base 102. The length of the support plate 101 is 300mm, the height of the reinforcing ribs 103 is 400mm, the height of the support plate 101 is 750mm, and the distance between the two sets of reinforcing ribs 103 is 200mm. This platform is specifically designed for comprehensive inspection and maintenance of various parts of the train coupler body, such as supporting 25T and 25TG couplers. The support plates 101, base 102, and reinforcing ribs 103 are all 12mm thick steel plates, formed by flame cutting or laser cutting, possessing excellent load-bearing capacity and stability, ensuring safety during maintenance.

[0022] Example: Reference Figures 1-4A first clamping structure 200 and a second clamping structure 500 are respectively provided on the bearing surface of the support plate 101 for clamping and maintenance of 25T or 25TG couplers. Specifically, the first clamping structure 200 includes a first lower clamping plate 201 fixedly connected to the bearing surface, and a first upper clamping plate 202 rotatably connected to the first lower clamping plate 201. When the first lower clamping plate 201 and the first upper clamping plate 202 are in working state, a first clamping channel 300 is formed between the first lower clamping plate 201 and the first upper clamping plate 202. The second clamping structure 500 includes a second lower clamping plate 501 fixedly connected to the bearing surface, and a second upper clamping plate 502 rotatably connected to the second lower clamping plate 501. When the second lower clamping plate 501 and the second upper clamping plate 502 are in working state, a second clamping channel 600 is formed between the second lower clamping plate 501 and the second upper clamping plate 502.

[0023] In the design of the first clamping structure 200 and the second clamping structure 500, the first lower clamping plate 201 and the second lower clamping plate 501 are both firmly fixed to the bearing surface of the support plate 101 by high-strength bolts or welding to ensure the stability and reliability of the clamping structure during maintenance. A first fixing rod 701 and a second fixing rod 702 are respectively fixedly connected to the first upper clamping plate 202 and the second upper clamping plate 502. A first connecting hole 204 and a second connecting hole 504 are respectively provided on the first lower clamping plate 201 and the second lower clamping plate 501, and the first connecting hole 204 and the second connecting hole 504 are opposite to each other. The first fixing rod 701 is connected to one set of first connecting holes 204 and second connecting holes 504. In the working state, the second fixing rod 702 can be fixedly connected to another set of first connecting holes 204 and second connecting holes 504. They are locked together using straight rod bolts, which pass through the first connecting holes 204 and second connecting holes 504 and extend to the outside of the first connecting holes 204 and second connecting holes 504 at both ends. They are then locked with nuts, so that the nuts abut against the outer wall of the first lower clamping plate 201 or the second lower clamping plate 501 respectively, thereby enhancing the stability of the entire clamping structure.

[0024] The first lower clamping plate 201 and the first upper clamping plate 202 are provided with the same clamping holes, which are the first clamping channels 300 formed in the working state. The diameter of the first clamping channel 300 formed in the working state is in the range of 100-300mm. The diameter in this device is 110mm or 112mm, which is used to clamp one end of the 25T or 25TG model coupler or close-fitting hook. Secondly, the second lower clamping plate 501 and the second upper clamping plate 502 are also provided with the same clamping holes, which are the second clamping channels 600 formed in the working state. The diameter of the second clamping channel 600 formed in the working state is in the range of 200-300mm. The diameter in this device is 215mm or 221mm, which is used to clamp the other end of the 25T or 25TG model coupler or close-fitting hook.

[0025] Specifically, to facilitate convenient rotation of the coupler in the clamped state, six sets of second limiting rollers 503 are rotatably connected to the second lower clamping plate 501 and the second upper clamping plate 502. The six sets of second limiting rollers 503 are adapted to the second clamping channel 600. Four sets of first limiting rollers 203 are rotatably connected to the first lower clamping plate 201 and the first upper clamping plate 202. The four sets of first limiting rollers 203 are adapted to the first clamping channel 300. Under the action of the first limiting rollers 203 and the second limiting rollers 503, the coupler can be effectively prevented from shifting or slipping during rotation, ensuring the stability of rotation. At the same time, the first limiting rollers 203 and the second limiting rollers 503 are both made of wear-resistant materials, such as stainless steel, which have good wear resistance and service life, reducing maintenance costs. In addition, for ease of operation, the maintenance platform can also be equipped with a rotary drive device, such as a self-locking motor, which is connected to the end of the coupler through a transmission mechanism to realize automatic rotation of the coupler, further improving maintenance efficiency.

[0026] Specifically, it also includes a limiting component 400, which is disposed on the first upper clamping plate 202. When the limiting component 400 is in the working state, the axis B of the limiting component 400 is perpendicular to the axis A. The limiting component 400 includes an extension plate 401 fixedly connected to the first upper clamping plate 202. A screw 402 is threadedly connected to the extension plate 401. One end of the screw 402 is provided with a locking element 403, and the other end of the screw 402 is provided with a handle 404. By rotating the handle 404, the screw 402 can be driven to move threadedly on the extension plate 401. When the locking element 403 of the screw 402 is in close contact with the side wall of the coupler, the coupler can be limited, preventing unnecessary movement of the coupler during maintenance and improving the safety and stability of maintenance.

[0027] Meanwhile, since the axis B of the limiting component 400 is perpendicular to axis A, when the limiting component 400 is in operation, it can effectively limit the coupler in the vertical direction, thereby further improving the practicality and reliability of the maintenance platform. Furthermore, the limiting component 400 has a simple structure, is easy to operate, and facilitates maintenance and replacement. This not only reduces maintenance costs but also significantly improves maintenance efficiency. During operation, it effectively reduces operational difficulty and prevents the coupler from being damaged by impacts during maintenance. In addition, concealed parts of the coupler, such as the bottom of the coupler cavity, can also be thoroughly inspected, effectively avoiding potential quality problems.

[0028] Components not described in detail in this article are existing technologies.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
