Abstract
Description
Technical Field
[0001] This utility model belongs to the field of rail vehicle technology, specifically relating to a lateral stop for rail vehicles. Background Technology
[0002] Lateral stops for rail vehicles are safety devices used to limit the lateral movement of rail vehicles on the track to prevent derailment or collisions with other vehicles in stations or depots. Lateral stops are typically installed at the ends of the track or in specific locations. Here are some common types of lateral stops: Fixed lateral stops: Constructed of robust concrete or metal structures, directly fixed to the side of the track; suitable for track ends where frequent adjustments or movements are not required; Movable lateral stops: Can be adjusted or moved as needed, facilitating rail vehicle maintenance and dispatch; typically hydraulically or spring-loaded, they absorb energy after a collision; Rubber-damped lateral stops: Use rubber or other elastic materials as a damper to reduce the impact force when a vehicle collides with the stop; suitable for applications requiring a certain level of cushioning.
[0003] Currently, the wear-resistant head inside the existing transverse stop of rail vehicles is fixedly connected to the rigid retaining ring by bolts. Since the impact is direct on the wear-resistant head, it will wear out and need to be replaced. However, with the bolt connection, the bolts need to be completely unscrewed to replace the wear-resistant head. However, the bolts may be lost, affecting the replacement efficiency. In addition, when the rigid retaining ring deforms under long-term impact and needs repair, the rigid retaining ring and the rubber are connected by an interference fit. Therefore, removing the rigid retaining ring from the rubber by bolts will cause wear and deformation of the bolt threads, making it difficult to use later. Removing it with external tools is also cumbersome. Based on this, a transverse stop for rail vehicles is proposed. Utility Model Content
[0004] The purpose of this utility model is to provide a lateral stop for rail vehicles that has a simple structure and reasonable design in order to solve the above problems.
[0005] This utility model achieves the above objectives through the following technical solutions:
[0006] A transverse stop for a rail vehicle includes a base plate, a rubber fixedly connected to the top of the base plate, a rigid retaining ring tightly attached inside the rubber, a wear-resistant head pressed onto the top of the rigid retaining ring, a fixing column installed inside the wear-resistant head, a bolt threadedly connected to the fixing column, and a fixing mechanism fixedly connected to the inner bottom of the rigid retaining ring.
[0007] As a further optimization of this utility model, the fixing mechanism includes a sleeve fixedly connected inside a rigid retaining ring, a sliding plate sealed and slidably connected inside the sleeve, a magnetic plate fixedly connected to the top of the sliding plate, a connecting pipe fixedly connected to the bottom of the sleeve, a liquid chamber opened inside the rigid retaining ring, the connecting pipe communicating with the interior of the liquid chamber, a connecting plate sealed and slidably connected inside the liquid chamber, and a locking block fixedly connected to the end of the connecting plate.
[0008] As a further optimization of this utility model, a slot is provided on the outer surface of the fixing column, and the slot is adapted to the card block.
[0009] As a further optimization of this utility model, the inner surface of the fixing column is fitted with the outer surface of the sleeve.
[0010] As a further optimization of this utility model, a magnetic block is installed at the bottom of the bolt, and the magnetic block has the opposite magnetism to the magnetic plate directly opposite it.
[0011] As a further optimization of this utility model, the outer surface of the fixing column is in contact with the inner surface and bottom of the rigid retaining ring.
[0012] The beneficial effects of this utility model are as follows:
[0013] This invention, through the setting of a fixing mechanism, allows for easy replacement of the wear-resistant head or repair of the rigid retaining ring. By rotating the bolt, the sliding plate slides upward along the inner surface of the sleeve, allowing the liquid in the liquid tank to flow back into the sleeve through the connecting pipe. This causes the connecting plate to pull the locking block out of the slot, allowing the fixing post to be removed for replacement of the wear-resistant head. At this point, rotating the bolt allows the locking block to enter the slot from below, and the rigid retaining ring can be removed from the rubber by pulling the fixing post. This design avoids bolt compression and deformation, saves resources, and is convenient to use. Attached Figure Description

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0021] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a transverse stop for a rail vehicle includes a base plate 1 with two through holes for connecting it to the rail vehicle via pins. A rubber 2 is fixedly connected to the top of the base plate 1, and a rigid retaining ring 3 is tightly fitted inside the rubber 2. A wear-resistant head 4 is press-fitted onto the top of the rigid retaining ring 3, with the top of the wear-resistant head 4 flush with the top of the rubber 2. A fixing post 5 is installed inside the wear-resistant head 4, and its outer surface fits against the inner surface and bottom of the rigid retaining ring 3. A bolt 6 is threadedly connected to the fixing post 5. A fixing mechanism is fixedly connected to the inner bottom of the rigid retaining ring 3, and the fixing mechanism includes a sleeve 7 fixedly connected inside the rigid retaining ring 3. The inner surface of the fixed column 5 is in contact with the outer surface of the sleeve 7. The sleeve 7 is sealed and slidably connected with a sliding plate 8. The top of the sliding plate 8 is fixedly connected with a magnetic plate 9. A magnetic block is installed at the bottom of the bolt 6. The magnetic block and the magnetic plate 9 are opposite in magnetism. The bottom of the sleeve 7 is fixedly connected with a connecting pipe 10. A liquid chamber 11 is opened in the rigid retaining ring 3. The connecting pipe 10 is connected to the inside of the liquid chamber 11. The sleeve 7, the connecting pipe 10 and the liquid chamber 11 are all filled with liquid. A connecting plate 12 is sealed and slidably connected in the liquid chamber 11. A locking block 13 is fixedly connected to the end of the connecting plate 12. A locking groove 14 is opened on the outer surface of the fixed column 5. The locking groove 14 is compatible with the locking block 13.
[0022] When the wear-resistant head 4 needs to be replaced, the bolt 6 is rotated in the reverse direction, causing the bolt 6 to attract the magnetic plate 9 through the magnetic block, which in turn drives the sliding plate 8 to slide upward along the inner surface of the sleeve 7. At this time, the sleeve 7 will draw liquid from the liquid tank 11 through the connecting pipe 10, causing the connecting plate 12 to slide into the liquid tank 11, and causing the locking block 13 to be pulled out of the locking groove 14. The fixing post 5 can then be removed from the rigid retaining ring 3 and the wear-resistant head 4, and the wear-resistant head 4 can be replaced. When reinstalling, first align the wear-resistant head 4 with the rigid retaining ring 3 and push the wear-resistant head 4 into the rubber 2. Then, rotate the bolt 6 in the forward direction, causing the bolt 6 to push the sliding plate 8 upward along the inner surface of the sleeve 7 through the magnetic plate 9. The inner surface of the sleeve 7 slides downward, allowing the liquid inside the sleeve 7 to enter the liquid tank 11 through the connecting pipe 10. This causes the connecting plate 12 to slide out of the liquid tank 11, allowing the locking block 13 to enter the locking groove 14, thus completing the replacement of the wear-resistant head 4. (It should be noted that although the wear-resistant head 4 and the rigid retaining ring 3 are connected by a press-fit process, when the wear-resistant head 4 is subjected to long-term impact, the press-fitted part between the wear-resistant head 4 and the rigid retaining ring 3 may become loose. Therefore, the wear-resistant head 4 can be replaced directly.) This replacement method does not require the bolt 6 to be completely unscrewed, and there will be no loss of the bolt 6, ensuring replacement efficiency.
[0023] When the rigid retaining ring 3 deforms under long-term impact and needs repair, the bolt 6 is rotated in the reverse direction. This causes the bolt 6 to attract the magnetic plate 9 through the magnetic block, which in turn drives the sliding plate 8 to slide upward along the inner surface of the sleeve 7. At this time, the sleeve 7 will draw liquid from the liquid tank 11 through the connecting pipe 10, causing the connecting plate 12 to slide into the liquid tank 11. This allows the locking block 13 to be pulled out of the slot 14, and the fixing post 5 can be removed from the rigid retaining ring 3 and the wear-resistant head 4. Then, the wear-resistant head 4 is removed, and the bolt 6 is rotated in the forward direction again. This causes the bolt 6 to push the sliding plate 8 downward along the inner surface of the sleeve 7 through the magnetic plate 9, allowing the liquid in the sleeve 7 to enter the liquid tank 11 through the connecting pipe 10. This causes the connecting plate 12 to slide out of the liquid tank 11, allowing the locking block 13 to enter the slot 14. Then, the rigid retaining ring 3 can be removed from the rubber 2 by pulling the fixing post 5. This process avoids the deformation of the bolt 6, saves resources, and is convenient to use without the need for external tools.
[0024] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
