Description

Technical Field

[0001] This utility model relates to the field of rail transit technology, specifically a combined anti-climb device for rail transit vehicles. Background Technology

[0002] A track anti-creep device is a device used to prevent railway tracks or construction rails from creeping, ensuring track stability and safety.

[0003] Most existing anti-climb devices for rail transit vehicles are integrated units. However, during installation, they need to be installed under the track to prevent the track from creeping. However, the space under the track is limited, making flexible installation impossible and resulting in slow installation speed. In addition, wedges are needed to fill the gaps. Since the wedges are set separately from the anti-climb device, the wedges may tilt during hammering. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a combined anti-climb device for rail transit vehicles, which has the advantages of separate installation and prevention of wedge tilting, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a combined anti-climb device for rail transit vehicles, including a base, with a disassembly plate one and a disassembly plate two respectively provided on the top of the base. A sliding wedge is slidably connected to the outer wall of the disassembly plate one. An extension shell is fixedly installed at the bottom of the base, and a fixing plate is fixedly installed at the bottom of the disassembly plate one. A rotating head is rotatably connected to the bottom of the extension shell, and a limit post is fixedly installed on the inner wall of the extension shell. A threaded post is fixedly installed on the top of the rotating head, and a guide post is fixedly installed on the top of the threaded post. A limit post is provided on the outer wall of the disassembly plate one. The groove has a limit slider fixedly installed on the outer wall of the sliding wedge, and a fixed shell one fixedly installed on the outer wall of the disassembly plate one. A fixed shell two is fixedly installed on the outer wall of the fixed shell one. A lifting plate is slidably connected to the inner wall of the fixed shell one. A pull column is fixedly installed on the top of the lifting plate, and an insert plate is fixedly installed on the bottom of the lifting plate. A telescopic block is slidably connected to the inner wall of the fixed shell two. A pull block is fixedly installed on the outer wall of the telescopic block. A spring one is provided on the inner wall of the fixed shell two. A sloping groove is opened on the top of the lifting plate, and a spring two is provided on the inner wall of the fixed shell one.

[0006] As a preferred technical solution of this utility model: the shape of the insert plate is adapted to the inner wall of the sliding wedge, and the insert plate is located above the inner wall of the sliding wedge.

[0007] As a preferred technical solution of this utility model: the bottom of the telescopic block is an inclined surface, and the bottom of the telescopic block is parallel to the top of the inclined groove.

[0008] As a preferred technical solution of this utility model: the shape of the limiting slider is adapted to the inner wall of the limiting groove, and the limiting slider is located inside the limiting groove.

[0009] As a preferred technical solution of this utility model: the threaded post is located on the inner wall of the fixing plate, and the threaded post and the fixing plate are threadedly connected.

[0010] As a preferred technical solution of this utility model: the number of the limiting posts is two, and the two limiting posts are symmetrically arranged on the inner wall of the extension shell, and the two limiting posts are adapted to the inner wall of the fixing plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This combined anti-climb device for rail transit vehicles involves placing the base under the rail, with the extended shells on both sides of the base protruding from the rail. The fixing plates at the bottom of disassembly plate one and disassembly plate two are then inserted into the base. The inner walls of the fixing plates are respectively fitted onto the outer walls of the guide post and the limiting post. Rotating the rotating head causes the threaded post to rotate, which in turn causes the threaded post to move the fixing plate downwards to the bottom of the extended shell through the threaded connection with the fixing plate. This fixes disassembly plate one and disassembly plate two to the sides of the rail.

[0013] 2. This combined anti-climb device for rail transit vehicles works by pulling a pull column, which in turn moves the lifting plate and the insert plate upwards, causing the insert plate to separate from the inner wall of the sliding wedge. At this point, the upward movement of the lifting plate moves the inclined groove upwards, causing the top of the inclined groove to fit against the bottom of the telescopic block. The upward force of the inclined groove then pushes the telescopic block into the interior of the fixed shell. When the lifting plate reaches the top of the telescopic block, the spring pushes the telescopic block to the bottom of the lifting plate, thus fixing the position of the lifting plate and the insert plate. At this point, the fixed relationship of the sliding wedge disappears. By hammering the fixed shell, the fixed shell moves the limiting slider within the inner wall of the limiting groove, filling the gap between the disassembly plate and the rail.

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] Please see Figure 1 - Figure 5 A combined anti-climb device for rail transit vehicles includes a base 1. The top of the base 1 is provided with a disassembly plate 2 and a disassembly plate 3. A sliding wedge 4 is slidably connected to the outer wall of the disassembly plate 2. An extension shell 5 is fixedly installed at the bottom of the base 1. A fixing plate 6 is fixedly installed at the bottom of the disassembly plate 2. A rotating head 7 is rotatably connected to the bottom of the extension shell 5. A limit post 10 is fixedly installed on the inner wall of the extension shell 5. A threaded post 8 is fixedly installed on the top of the rotating head 7. A guide post 9 is fixedly installed on the top of the threaded post 8. A limit groove 11 is formed on the outer wall of the disassembly plate 2. A sliding wedge 4 is fixedly installed on the outer wall of the sliding wedge 4. The limiting slider 12, the outer wall of the disassembly plate 12 is fixedly installed with a fixed shell 13, the outer wall of the fixed shell 13 is fixedly installed with a fixed shell 2 14, the inner wall of the fixed shell 13 is slidably connected with a lifting plate 15, the top of the lifting plate 15 is fixedly installed with a pull column 16, the bottom of the lifting plate 15 is fixedly installed with a plug plate 17, the inner wall of the fixed shell 2 14 is slidably connected with a telescopic block 18, the outer wall of the telescopic block 18 is fixedly installed with a pull block 20, the inner wall of the fixed shell 2 14 is provided with a spring 19, the top of the lifting plate 15 is provided with a sloping groove 21, and the inner wall of the fixed shell 13 is provided with a spring 22.

[0022] In the above structure, the guide post 9 guides the fixing plate 6 so that after the fixing plate 6 is inserted into the inner wall of the extension shell 5, its inner wall is sleeved on the outer wall of the guide post 9, thereby guiding the fixing plate 6 downward.

[0023] In a preferred embodiment, the shape of the insert plate 17 is adapted to the inner wall of the sliding wedge 4, and the insert plate 17 is located above the inner wall of the sliding wedge 4.

[0024] In the above structure, the downward movement of the lifting plate 15 causes the insertion plate 17 to move downward, thereby causing the insertion plate 17 to enter the inner wall of the sliding wedge 4, thus fixing the position of the sliding wedge 4.

[0025] In a preferred embodiment, the bottom of the telescopic block 18 is a slope, and the bottom of the telescopic block 18 is parallel to the top of the slope groove 21.

[0026] In the above structure, when the lifting plate 15 moves upward, the lifting plate 15 drives the inclined groove 21 to move upward, so that the top of the inclined groove 21 fits with the bottom of the telescopic block 18. At this time, the upward force of the inclined groove 21 pushes the telescopic block 18 into the interior of the fixed shell 14. When the lifting plate 15 reaches above the telescopic block 18, the spring 19 pushes the telescopic block 18 to the bottom of the lifting plate 15, thereby fixing the position of the lifting plate 15 and fixing the position of the insert plate 17.

[0027] In a preferred embodiment, the shape of the limiting slider 12 is adapted to the inner wall of the limiting groove 11, and the limiting slider 12 is located inside the limiting groove 11.

[0028] In the above structure, the limiting slider 12 is limited by the limiting groove 11, so that the limiting slider 12 can only slide on the inner wall of the limiting groove 11 when it moves, so that the sliding wedge 4 will not tilt when it moves.

[0029] In a preferred embodiment, the threaded post 8 is located on the inner wall of the fixing plate 6, and the threaded post 8 is threadedly connected to the fixing plate 6.

[0030] In the above structure, by rotating the threaded column 8, the threaded column 8 drives the fixed plate 6 to move downward through the threaded connection with the fixed plate 6, thereby causing the fixed plate 6 to move towards the bottom of the extension shell 5, so that the fixed plate 6 is fixed inside the extension shell 5.

[0031] In a preferred embodiment, there are two limiting posts 10, and the two limiting posts 10 are symmetrically arranged on the inner wall of the extension shell 5, and the two limiting posts 10 are adapted to the inner wall of the fixing plate 6.

[0032] In the above structure, the inner walls on both sides of the fixing plate 6 are limited by two limiting posts 10, so that when the fixing plate 6 moves, its inner walls on both sides can only slide on the outer wall of the limiting posts 10, thus preventing the fixing plate 6 from tilting when it moves.

[0033] Working principle: Place the base 1 below the rail, so that the extension shells 5 on both sides of the base 1 protrude from the sides of the rail. Then, insert the disassembly plate 2 and disassembly plate 3 into the base 1, so that the fixing plate 6 at the bottom of the disassembly plate 2 and disassembly plate 3 enters the inner wall of the extension shell 5. At this time, the inner wall of the fixing plate 6 is respectively sleeved on the outer wall of the guide post 9 and the limiting post 10. Then, rotate the rotating head 7, so that the rotating head 7 drives the threaded post 8 to rotate, so that the threaded post 8 drives the fixing plate 6 to move downward to the bottom of the extension shell 5 through the threaded connection with the fixing plate 6, so that the disassembly plate 2 and disassembly plate 3 are fixed on both sides of the rail. Then, by pulling the pull post 16, the pull post 16 drives the lifting plate 15 and the insert plate 17 to move upward, so that the insert plate 17 slides against the rail. The inner wall of wedge 4 separates. At this time, the upward movement of the lifting plate 15 drives the inclined groove 21 to move upward, so that the top of the inclined groove 21 fits with the bottom of the telescopic block 18. At this time, the upward force of the inclined groove 21 pushes the telescopic block 18 into the interior of the fixed shell 14. When the lifting plate 15 reaches above the telescopic block 18, the spring 19 pushes the telescopic block 18 to the bottom of the lifting plate 15, so that the position of the lifting plate 15 is fixed, and the position of the insert plate 17 is fixed. At this time, the fixed relationship of the sliding wedge 4 disappears. By hammering the fixed shell 14, the fixed shell 14 drives the limiting slider 12 to move on the inner wall of the limiting groove 11, so that the sliding wedge 4 blocks the gap between the disassembly plate 2 and the rail.

[0034] 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.
