[0001] This utility model relates to the field of controllable parking device technology, specifically a controllable parking device with wear-resistant pads for use at the tail of a railway marshalling yard. Background Technology

[0002] Controllable parking devices (such as the WKT-1 type) achieve vehicle deceleration and stopping through friction between the brake rail and the inner side of the wheel, and are widely used at the tail of railway marshalling yards. In existing technologies, the friction surface of the brake rail suffers from reduced thickness and curvature deformation due to long-term wear, resulting in decreased braking force and even the risk of runaway. However, traditional solutions require frequent replacement of the brake rail, and the cost of a single set is approximately 15,000 yuan, leading to a relatively high operating cost for controllable parking devices. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the purpose of this invention is to provide a controllable parking device with wear-resistant pads, so as to solve the problem of reduced braking force of the brake rail caused by the reduction in thickness and curvature deformation due to long-term wear of the brake rail friction surface in the prior art.

A stop block is fixedly connected to the upper surface of the parking device body. A U-shaped wear-resistant pad is fitted onto the surface of the stop block. A trapezoidal groove is formed on the side of the stop block. A trapezoidal pad is fitted onto the inner wall of both the trapezoidal groove and the inner wall of the U-shaped wear-resistant pad. A second threaded hole is formed on the inner wall of the trapezoidal pad. A double-ended screw is threaded onto the inner wall of the second threaded hole. A bearing is fixedly connected to the surface of the double-ended screw. A connecting plate is fixedly connected to the outer ring of the bearing and the upper surface of the U-shaped wear-resistant pad. A rotating block is fixedly connected to the upper surface of the double-ended screw.

[0006] Furthermore, the surface of the double-ended screw is provided with two sections of threads in opposite directions, and the axis of the double-ended screw coincides with the center of the rotating block.

[0007] Furthermore, the contact surface between the trapezoidal pad and the trapezoidal groove is an inclined surface, and the angle between the inclined surface of the trapezoidal pad and the horizontal plane is 70°.

[0008] Furthermore, the front of the U-shaped wear-resistant pad has a rectangular hole, the inner wall of the rectangular hole is fitted with an indicator ring, the back of the indicator ring is fixedly connected to the front of the trapezoidal pad, the inner wall of the indicator ring is fitted with a scale, and the back of the scale is fixedly connected to the front of the U-shaped wear-resistant pad.

[0009] Furthermore, the length of the strip hole is greater than the diameter of the fixing bolt, and the width of the strip hole is equal to the diameter of the fixing bolt.

[0010] Furthermore, a circular plate is fixedly connected to the surface of the double-ended screw, a locking groove is formed on the surface of the circular plate, a locking hole is formed inside the connecting plate, a locking pin is fitted to the inner wall of the locking hole and the inner wall of the locking groove, a limit block is fixedly connected to the upper surface of the locking pin, and the bottom of the limit block is fitted to the upper surface of the circular plate.

[0011] Compared with the prior art, the technical effects achieved by this utility model are as follows:

[0012] 1. The controllable parking device with wear-resistant pad of this utility model, through the cooperation of a stop block, U-shaped wear-resistant pad, trapezoidal groove, trapezoidal pad, second threaded hole, double-ended screw, bearing, connecting plate and rotating block, allows the user to adjust the position of the brake rail on the controllable parking device according to the wear degree of the brake rail and the fatigue degree of the brake spring on the main body of the parking device, so that the worn brake rail can still effectively brake the wheel, thereby effectively improving the service life of the brake rail of the controllable parking device.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 As shown, the controllable parking device with wear-resistant pads of this utility model mainly includes a parking device body 1. A support plate 2 is fixedly connected to the upper surface of the parking device body 1. A brake rail 3 is attached to the upper surface of the support plate 2. A strip-shaped hole 4 is opened inside the brake rail 3. A fixing bolt 5 is attached to the inner wall of the strip-shaped hole 4. A first threaded hole 6 is opened inside the support plate 2. The inner wall of the first threaded hole 6 is attached to the surface of the fixing bolt 5. A stop block 7 is fixedly connected to the upper surface of the parking device body 1. The surface of the stop block 7... A U-shaped wear-resistant pad 8 is fitted together. A trapezoidal groove 9 is opened on the side of the stop block 7. A trapezoidal pad 10 is fitted together on the inner wall of the trapezoidal groove 9 and the inner wall of the U-shaped wear-resistant pad 8. A second threaded hole 11 is opened on the inner wall of the trapezoidal pad 10. A double-ended screw 12 is threadedly connected to the inner wall of the second threaded hole 11. A bearing 13 is fixedly connected to the surface of the double-ended screw 12. A connecting plate 14 is fixedly connected to the outer ring of the bearing 13 and the upper surface of the U-shaped wear-resistant pad 8. A rotating block 15 is fixedly connected to the upper surface of the double-ended screw 12.

[0032] The length of the strip hole 4 is greater than the diameter of the fixing bolt 5, and the width of the strip hole 4 is equal to the diameter of the fixing bolt 5. The surface of the double-ended screw 12 is provided with two threads in opposite directions. The axis of the double-ended screw 12 coincides with the center of the rotating block 15. The contact surface between the trapezoidal pad 10 and the trapezoidal groove 9 is an inclined surface. The angle between the inclined surface of the trapezoidal pad 10 and the horizontal plane is 70°.

[0033] It should be noted that the brake rail 3 can be fixed on the support plate 2 by the cooperation of the fixing bolt 5 and the first threaded hole 6. At the same time, since the length of the strip hole 4 is greater than the diameter of the fixing bolt 5, the fixing position of the brake rail 3 can be adjusted left and right. When the user rotates the rotating block 15, the distance between the upper and lower trapezoidal pads 10 can be changed by the cooperation of the double-ended screw 12 and the second threaded hole 11. After the distance between the upper and lower trapezoidal pads 10 is changed, the position of the U-shaped wear-resistant patch 8 can be changed by the cooperation of the trapezoidal pad 10 and the trapezoidal groove 9. By changing the position of the U-shaped wear-resistant patch 8, the installation position of the brake rail 3 can be changed.

[0034] The U-shaped wear-resistant pad 8 has a rectangular hole 16 on its front side. An indicator ring 17 is fitted into the inner wall of the rectangular hole 16. The back of the indicator ring 17 is fixedly connected to the front of the trapezoidal pad 10. A scale 18 is fitted into the inner wall of the indicator ring 17. The back of the scale 18 is fixedly connected to the front of the U-shaped wear-resistant pad 8. Through the cooperation of the indicator ring 17 and the scale 18, the user can intuitively judge the distance between the upper and lower trapezoidal pads 10, and thus the user can accurately adjust the distance between the upper and lower trapezoidal pads 10 to a suitable size.

[0035] A circular plate 19 is fixedly connected to the surface of the double-ended screw 12. A locking groove 20 is opened on the surface of the circular plate 19. A locking hole 21 is opened inside the connecting plate 14. A locking pin 22 is fitted to both the inner wall of the locking hole 21 and the inner wall of the locking groove 20. A limit block 23 is fixedly connected to the upper surface of the locking pin 22. The bottom of the limit block 23 is fitted to the upper surface of the circular plate 19.

[0036] It should be noted that when the locking pin 22 is inserted into the locking groove 20 and the locking hole 21, the locking pin 22 is limited by the limiting block 23. Through the cooperation of the locking pin 22, the locking groove 20 and the locking hole 21, the double-headed screw 12 cannot rotate. During the use of the controllable parking device, the distance between the upper and lower trapezoidal pads 10 will not decrease due to vibration, so that the U-shaped wear-resistant pad 8 on the controllable parking device can stably limit the brake rail 3.

[0037] The working principle of this utility model is as follows: The brake rail 3 can be fixed to the rail support plate 2 by the cooperation of the fixing bolt 5 and the first threaded hole 6. When the wheel contacts the brake rail 3, the hydraulic pump station operates, stretching the brake spring on the parking device body 1 through the oil cylinder. The stretched brake spring then makes the brake rail 3 tightly contact the wheel. At this time, the friction between the brake rail 3 and the wheel can brake the wheel. When the parking device needs to release, the hydraulic pump station operates to inject oil into the oil cylinder, compressing the brake spring and retracting the brake rail 3, allowing the locomotive and rolling stock to pass freely. (The oil cylinder and brake spring on the parking device body 1 are internal structures of the parking device body 1, and the positions of the oil cylinder and brake spring within the parking device body 1 are known technologies. The hydraulic pump station injecting oil into the oil cylinder is existing technology.)

[0038] When the brake rail 3 wears or the brake spring on the parking device body 1 loses elasticity due to fatigue, first loosen the brake rail 3 by rotating the fixing bolt 5. Then, remove the locking pin 22 from the locking groove 20 and locking hole 21, and rotate the rotating block 15 to rotate the double-ended screw 12. At this time, the distance between the upper and lower trapezoidal pads 10 can be changed by the cooperation of the double-ended screw 12 and the second threaded hole 11. The position of the U-shaped wear-resistant patch 8 can be changed by the cooperation of the trapezoidal pad 10 and the trapezoidal groove 9. Then, by changing the position of the U-shaped wear-resistant patch 8, the installation position of the brake rail 3 can be changed. The brake rail 3 can be fixed in the new position by the cooperation of the fixing bolt 5 and the first threaded hole 6. At this time, by changing the position of the brake rail 3 on the controllable parking device, the brake rail 3 can still effectively brake the wheels.

[0039] After the user adjusts the distance between the upper and lower trapezoidal pads 10 to a suitable size, by inserting the locking pin 22 into the locking groove 20 and the locking hole 21, the double-headed bolt can be prevented from rotating under the cooperation of the locking pin 22, the locking groove 20 and the locking hole 21. This ensures that the distance between the upper and lower trapezoidal pads 10 will not decrease due to vibration during the use of the controllable parking device, so that the U-shaped wear-resistant pad 8 on the controllable parking device can stably limit the brake rail 3.

[0040] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
