[0026] 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.

[0027] This utility model provides the following technical solution: a planing-type anti-climb device for rail vehicles.

[0028] Example 1: The locking block 10 and the locking slot 9 allow the lower connecting plate 5 and the mating plate 6 to quickly engage, as shown below. Figures 1-8 As shown, it includes a mounting base 1 and an anti-climbing tooth 4. The upper surface of the mounting base 1 is bolted to an energy-absorbing tube 3, and the end of the energy-absorbing tube 3 is fixedly connected to a docking plate 6. The lower surface of the anti-climbing tooth 4 is bolted to a lower connecting plate 5, and the lower connecting plate 5 and the docking plate 6 are interlocked.

[0029] A fixing block 8 is fixedly connected to the lower surface of the lower plate 5, and the fixing blocks 8 are symmetrically distributed on both sides of the lower plate 5. The surface of the fixing block 8 is provided with a slot 9. The upper surface of the connecting plate 6 is provided with an installation slot 15 corresponding to the fixing block 8. The locking block 10 corresponds to the slot 9 one by one, and the upper surface of the locking block 10 is inclined. Limiting blocks 12 are fixedly connected to both the upper and lower sides of the locking block 10.

[0030] When it is necessary to connect the lower plate 5 and the connecting plate 6, insert the fixing block 8 on the lower surface of the lower plate 5 into the mounting groove 15 on the upper surface of the connecting plate 6. At this time, the fixing block 8 will push the inclined surface of the locking block 10, causing the locking block 10 to drive the limiting block 12 to slide inside the limiting groove 13. At this time, the connecting spring 14 will be squeezed. When the lower surface of the lower plate 5 is in contact with the upper surface of the connecting plate 6, the locking block 10 and the locking groove 9 are in the same horizontal direction. At this time, the locking block 10 moves back under the action of the limiting block 12 and the connecting spring 14. Finally, the locking block 10 enters the interior of the locking groove 9, that is, the lower plate 5 and the connecting plate 6 are connected. The operation process is quick and convenient.

[0031] Example 2: By using the spiral-shaped scraper groove 7, the energy-absorbing tube 3 can have a longer stroke side during planing, thereby allowing the impact potential energy to be better converted into other potential energies, improving safety, such as... Figures 2-4 As shown, the surface of the energy-absorbing tube 3 is provided with a scraping groove 7, and the scraping groove 7 is evenly distributed on the surface of the energy-absorbing tube 3. The scraping groove 7 is spiral-shaped. A planing blade 2 is fixedly connected to the inner wall of the mounting base 1, and the planing blade 2 is located inside the scraping groove 7.

[0032] When an impact occurs, the energy-absorbing tube 3 moves downward inside the mounting base 1. At this time, the planing blade 2 scrapes off the energy-absorbing tube 3, converting the kinetic energy of the impact force into other forms of energy, minimizing the negative impact of the impact. The scraping groove 7 is spirally designed, which increases the stroke of the energy-absorbing tube 3, thereby allowing the potential energy generated by the impact to be better converted into other forms of potential energy, improving safety.

[0033] Example 3: The push block 16 and auxiliary spring 17 assist in disassembly. Figures 6-8 As shown,

[0034] The docking plate 6 has a sliding locking block 10 inside, and a handle 11 is fixedly connected to the end of the locking block 10. The docking plate 6 also has a sliding pushing block 16 inside. The docking plate 6 has a limiting groove 13 that corresponds one-to-one with the limiting block 12 inside. The surface of the limiting block 12 is fixedly connected to a connecting spring 14, and the other side of the connecting spring 14 is fixedly connected to the inner wall of the docking plate 6.

[0035] The surface of the push block 16 is in contact with the inner wall of the docking plate 6, and the push blocks 16 are distributed at equal angles on the upper surface of the docking plate 6. An auxiliary spring 17 is fixedly connected to the lower surface of the push block 16, and the other side of the auxiliary spring 17 is fixedly connected to the inner wall of the docking plate 6.

[0036] When it is necessary to disassemble the lower plate 5 and the docking plate 6, the handle 11 can be pulled to move the end of the handle 11 out of the slot 9. At this time, the lower plate 5 and the docking plate 6 are not in a locked state, which allows the anti-climbing tooth 4 and the energy-absorbing tube 3 to separate. The disassembly process is simple. During the docking process of the lower plate 5 and the docking plate 6, the lower plate 5 will push the push block 16, causing the push block 16 to move in the direction of squeezing the auxiliary spring 17. Thus, during the disassembly process, when the lower plate 5 and the docking plate 6 are not in a locked state, the push block 16 will rise under the action of the auxiliary spring 17. At this time, the push block 16 and the auxiliary spring 17 play a role in assisting the separation of the lower plate 5 and the docking plate 6, simplifying the disassembly steps and improving work efficiency.

[0037] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
