Detailed Implementation

[0027] The following is a detailed description of a rail vehicle coupler buffer disassembly and assembly bracket provided by this utility model, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are listed as best and preferred embodiments; other alternative methods may be used by those skilled in the art. Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0028] like Figure 1 , Figure 3 and Figure 5As shown, an embodiment of this utility model provides a rail vehicle coupler buffer disassembly and assembly bracket, including: a lifting assembly 1 and a lifting assembly 2; the lifting assembly 1 includes a horizontal plate 101, a gear 102 rotatably connected to the middle of the horizontal plate 101, a motor 103 providing driving force fixedly mounted at the bottom of the horizontal plate 101, a drive wheel 104 fixedly mounted at the top of the output shaft of the motor 103, the outer wall of the drive wheel 104 meshing with the gear 102, the outer wall of the gear 102 meshing with a driven wheel 105, and a rotating ring 10 fixedly mounted at the bottom of the driven wheel 105. 6. The outer wall of the rotating ring 106 is rotatably connected to the inner wall of the horizontal plate 101. The inner wall of the driven wheel 105 is threaded with a screw 107. The top of the screw 107 is fixedly mounted with a top plate 108. There are four sets of driven wheels 105, rotating ring 106 and screw 107. The four sets of driven wheels 105, rotating ring 106 and screw 107 are evenly distributed on the periphery of the gear 102. By limiting the number and position of driven wheels 105, rotating ring 106 and screw 107, it is beneficial to improve the stability and reliability of the top plate 108 and the lifting assembly 2.

[0029] like Figure 1 , Figure 3 and Figure 6 As shown, the lifting assembly 2 includes a fixing frame 201 installed on the top of the top plate 108. A support plate 202 is fixedly mounted on the top of the fixing frame 201. A groove 203 is formed on the outer wall of the support plate 202. A clamping plate 204 is slidably connected to the inner wall of the groove 203. A connecting groove 205 is formed on the outer wall of the clamping plate 204. A fixing bolt 206 is threadedly connected to the outer wall of the support plate 202. The fixing bolt 206 passes through the support plate 202 and is threadedly connected to the connecting groove 205. The support plate 202 supports the bottom of the coupler buffer, thereby supporting the coupler buffer. Then, according to the width of the coupler buffer, the clamping plate 204 is pulled to a suitable position. Finally, the fixing bolt 206 passes through the connection groove 205 on the clamping plate 204 and is connected and fixed, thereby improving the adaptability of the device.

[0030] like Figure 3 As shown, a limiting groove 207 is provided on the inner wall of the slide groove 203. A limiting block 208 is slidably connected to the inner wall of the limiting groove 207. The side of the limiting block 208 away from the limiting groove 207 is fixedly connected to the card plate 204. By setting the limiting groove 207 and the limiting block 208, it is beneficial to limit the card plate 204 during the movement of the card plate 204, thereby improving the stability of the card plate 204 in movement and use.

[0031] like Figure 2 and Figure 6As shown, a groove 209 is provided on the side of the card plate 204 away from the slide groove 203. An anti-slip pad 210 is fixedly installed on the inner wall of the groove 209. By setting the groove 209 and the anti-slip pad 210, it is beneficial to contact the anti-slip pad 210 with the coupler buffer, thereby improving the friction between the card plate 204 and the coupler buffer.

[0032] like Figure 1 and Figure 2 As shown, baffles 109 are fixedly installed at the bottom of both the horizontal plate 101 and the top plate 108. A folding cloth 110 is fixedly installed between the two sets of baffles 109. By setting baffles 109 and folding cloth 110, it is beneficial to cover the parts on the lifting assembly 1 with the folding cloth 110, thereby improving the aesthetics of the device, while not affecting the lifting operation of the top plate 108.

[0033] like Figure 2 and Figure 5 As shown, a limiting tube 111 is fixedly mounted at the bottom of the horizontal plate 101. The outer wall of the screw 107 is slidably connected to the inner wall of the limiting tube 111. A base plate 112 is fixedly mounted at the bottom of the limiting tube 111. By setting the limiting tube 111 and the base plate 112, it is beneficial to improve the stability of the screw 107 when it moves through the limiting tube 111, thereby improving the stability of the device when it moves.

[0034] The technical solution provided by this utility model, during operation, drives the drive wheel 104 to rotate via the motor 103, drives the gear 102 to rotate via the rotation of the drive wheel 104, drives the four driven wheels 105 to rotate via the rotation of the gear 102, drives the screw 107 to move longitudinally via the rotation of the driven wheels 105, and drives the top plate 108 and the lifting assembly 2 to move longitudinally via the longitudinal movement of the screw 107. This enables the lifting of coupler buffers of different heights, thereby reducing the need for manual intervention and improving the efficiency of assembling and disassembling coupler buffers.

[0035] The coupler buffer is supported by the support plate 202 and the bottom of the coupler buffer. Then, the clamping plate 204 is pulled to a suitable position according to the width of the coupler buffer. Finally, the fixing bolts 206 are used to connect and fix the coupler buffer through the connecting grooves 205 on the support plate 202 and the clamping plate 204, thereby improving the adaptability of the device.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
