Description

Technical Field

[0001] This utility model relates to the field of disassembly and assembly technology of coupler buffer devices, specifically to a disassembly and assembly device for coupler buffer devices. Background Technology

[0002] Coupler buffer devices are an indispensable and important component in railway vehicles. They are mainly used to absorb and mitigate longitudinal impact forces and vibrations generated during train operation due to changes in traction force or collisions between vehicles.

[0003] This type of buffer device typically consists of a coupler, a coupler tail frame, a front drag plate, a buffer, and a rear drag plate, and is installed inside the traction beam at the end of the undercarriage frame.

[0004] However, after prolonged use, the shock absorber needs to be disassembled and replaced periodically for safety reasons. Traditional disassembly methods often rely on manual operation, which is not only labor-intensive but also inefficient. Because the shock absorber is installed inside the hook end frame and is connected to the front and rear plates, and the shock absorber and the rear plates normally have a preload within the hook end frame, this preload will tightly clamp the rear plates connected to the shock absorber within the hook end frame, making shock absorber disassembly inconvenient. Traditional disassembly methods require working under the frame, posing significant safety hazards. Utility Model Content

[0005] The purpose of this invention is to provide a disassembly and assembly device for a coupler buffer device, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a base plate, wheels mounted on the lower surface of the base plate, and a support plate above the base plate. A lifting mechanism is provided between the base plate and the support plate. A levering mechanism is provided on the upper side of the support plate, and a clamping mechanism is provided on the upper side of the levering mechanism. The lifting mechanism includes a support cover and a lower toothed plate. The support cover is slidably connected to the upper surface of the base plate. An upper toothed plate is slidably connected inside the support cover. The base plate is divided into two identical parts, left and right. The upper toothed plate is fixedly connected to the right side of the base plate. The lower toothed plate is slidably connected inside the support cover and fixedly connected to the left side of the base plate. A rocker arm is meshed between the upper and lower toothed plates. The rocker arm extends through the support cover to the outside of the support cover. A protrusion is fixedly connected to the upper surface of the base plate. A slider is slidably connected to the lower side of the support plate. A support rod is rotatably connected between the protrusion and the slider. A rotating shaft is rotatably connected between the support rods.

[0007] Preferably, the support rod has an opening in the middle for rotation.

[0008] Preferably, the slider is provided with a bolt assembly, which is used to limit the movement of the support plate.

[0009] Preferably, a slide bar is slidably provided on the rocker arm, and an insertion port is provided on one side of the support cover, through which the slide bar can be inserted into the support cover. The slide bar is used to limit the rotation of the rocker arm.

[0010] Preferably, the actuating mechanism includes a slide groove, which is formed on the upper surface of the support plate. A slide table is slidably connected in the slide groove, and a rocker arm is rotatably connected in the slide table. The rocker arm extends through the slide table to the outside of the slide table. A rack is fixedly connected to the upper surface of the support plate, and the rack meshes with the rocker arm. A nut is threaded onto the rocker arm.

[0011] Preferably, the nut is used to limit the position of the support plate and the slide.

[0012] Preferably, the clamping mechanism includes a two-jaw chuck, which is fixedly connected to the right side of the slide table. The two-jaw chuck has a jaw groove, and a jaw block is slidably connected in the jaw groove. A threaded disc is rotatably connected in the two-jaw chuck, and a helical toothed rod is rotatably connected in the two-jaw chuck. The helical toothed rod is meshed with the threaded disc. A worm gear is fixedly connected to the right side of the threaded disc, and a worm groove is opened on the left side of the jaw block. The worm gear is meshed with the worm groove.

[0013] Compared with the prior art, this utility model provides a disassembly and assembly device for a coupler buffer device, which has the following beneficial effects:

[0014] 1. The clamping mechanism is used to lock the coupler. After the coupler is locked, it is pushed by the lever mechanism to release the preload. The coupler does not need to be in contact with the coupler part at all during the process, which prevents injury to the user during the removal of the coupler. Specifically, the helical toothed rod is rotated to make the threaded disc mesh and rotate. The helical toothed disc is equipped with worm gears that mesh with the claw blocks. During the rotation of the helical toothed rod, the claw blocks clamp the coupler and cooperate with the lever mechanism to complete the quick disassembly.

[0015] 2. The lever mechanism is used to push the slide table, thereby driving the clamping mechanism to disassemble the coupler. Specifically, by shaking the rocker arm, the rocker arm rolls on the rack and pinion while driving the slide table to move. The slide table drives the clamping mechanism to disassemble the coupler using a mechanical structure, preventing the preload from affecting the disassembly speed.

[0016] 3. The lifting mechanism is used to lift the disassembly coupler platform. Then, the nut on the rocker arm is used to limit the height of the support plate. The lifted support plate can also slide for easy and quick movement. The nut on the rocker arm can be used to completely fix the support plate for easy subsequent disassembly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] Example 1:

[0027] Please see Figure 1-5 This utility model provides a technical solution: it includes a base plate 1, wheels 2 disposed on the lower surface of the base plate 1, and a support plate 3 above the base plate 1. A lifting mechanism 4 is disposed between the base plate 1 and the support plate 3. A levering mechanism 5 is disposed on the upper side of the support plate 3, and a clamping mechanism 6 is disposed on the upper side of the levering mechanism 5. The lifting mechanism 4 includes a support cover 401 and a lower toothed plate 403. The support cover 401 is slidably connected to the upper surface of the base plate 1, and an upper toothed plate 402 is slidably connected inside the support cover 401. The base plate 1 is divided into two identical parts, left and right. The upper toothed plate 402 is connected to the base plate. The right side is fixedly connected, the lower toothed plate 403 is slidably connected inside the support cover 401, the lower toothed plate 403 is fixedly connected to the left side of the base plate 1, the upper toothed plate 402 and the lower toothed plate 403 are meshed with a rocker arm 404, the rocker arm 404 passes through the support cover 401 and extends to the outside of the support cover 401, the upper surface of the base plate 1 is fixedly connected with a protrusion 405, the lower side of the support plate 3 is slidably connected with a slider 406, the protrusion 405 and the slider 406 are rotatably connected with a support rod 407, and the support rods 407 are rotatably connected with a rotating shaft 408.

[0028] Furthermore, the support rod 407 has an opening in the middle for rotation.

[0029] Furthermore, a bolt assembly is provided on the slider 406, which is used to limit the movement of the support plate 3.

[0030] Furthermore, a bolt assembly is provided on the slider 406, which is used to limit the movement of the support plate 3.

[0031] Furthermore, a slide bar is slidably provided on the rocker arm 404, and an insertion port is provided on one side of the support cover 401, through which the slide bar can be inserted into the support cover 401. The slide bar is used to limit the rotation of the rocker arm 404.

[0032] By rotating the rocker arm 404, the upper toothed plate 402 and the lower toothed plate 403 are brought closer or further apart. The rocker arm 404 rotates in the support cover 401. Under the action of the rocker arm 404, the upper toothed plate 402 and the lower toothed plate 403 are brought closer or further apart horizontally. The base plate 1 is brought closer or further apart by the upper toothed plate 402 and the lower toothed plate 403. When the two parts of the base plate 1 are close to each other, the support rod 407 raises the support plate 3 to a higher position. The user can twist the slide bar set on the rocker arm 404 at a suitable position. The slide bar cannot rotate between the rocker arm 404 and the support cover 401. The height of the support rod 407 can be limited by the slide bar. The user can push the support plate 3 to quickly approach the coupler to be disassembled. At a suitable position, the user can limit the position of the support plate 3 by twisting the bolt assembly. Then, the rocker arm 503 is rotated. The rocker arm 503 rolls above the rack 504 and drives the slide table 502 to approach the coupler.

[0033] Example 2:

[0034] Please see Figure 1-5 Furthermore, in conjunction with Embodiment 1, it is further obtained that the actuating mechanism 5 includes a slide groove 501, which is formed on the upper surface of the support plate 3. A slide table 502 is slidably connected in the slide groove 501, and a rocker arm 503 is rotatably connected in the slide table 502. The rocker arm 503 extends through the slide table 502 to the outside of the slide table 502. A rack 504 is fixedly connected to the upper surface of the support plate 3. The rack 504 is meshed with the rocker arm 503, and a nut 505 is threaded onto the rocker arm 503.

[0035] Furthermore, nut 505 is used to limit the placement plate 3 and slide 502.

[0036] Furthermore, the clamping mechanism 6 includes a two-jaw chuck 601, which is fixedly connected to the right side of the slide table 502. A jaw groove 602 is formed within the two-jaw chuck 601, and a jaw block 603 is slidably connected within the jaw groove 602. A threaded disc 604 is rotatably connected within the two-jaw chuck 601, and a helical gear 605 is rotatably connected within the two-jaw chuck 601. The helical gear 605 meshes with the threaded disc 604. A worm gear 606 is fixedly connected to the right side of the threaded disc 604, and a worm groove 607 is formed on the left side of the jaw block 603. The worm gear 606 meshes with the worm groove 607. The clamping mechanism 6 can be operated by rotating the helical gear 604. The toothed rod 605 causes the helical threaded disc 604 to rotate, which in turn drives the worm gear 606 to rotate. The worm gear 606 and the claw block 603 are meshed. Under the rotation of the helical toothed rod 605, the claw block 603 can be moved closer to or away from the center of the two-jaw chuck 601. When the claw blocks 603 are close to each other, they can clamp the coupler at the center of the claw blocks 603. When the claw blocks 603 are far apart, they can release the clamped coupler. After clamping the coupler, the user can apply a pushing or pulling force to the coupler by rotating the rocker arm 503, which can easily eliminate the preload generated by the coupler and facilitate the quick disassembly of the coupler.

[0037] In actual operation, when this device is used, the user places it on the track. When the device is pushed, the wheel 2 rolls on the track surface and approaches the coupler. The user can turn the rocker arm 404 to bring the base plates 1 closer together. During the process of the base plates 1 approaching each other, the support rod 407 is pushed by the bracket 405, and the longitudinal angle between the support rods 407 becomes smaller. The support plate 3 is pushed and lifted by the support rods 407. When the two-jaw chuck 601 is at the same level as the coupler, the user can tighten the bolt assembly two to approach the support. When the cover 401 and the bolt assembly 2 are in contact with the support cover 401, the rocker arm 404 cannot rotate, and the height of the support rod 407 is limited. The user can push the support plate 3 close to the coupler. The two-jaw chuck 601 is driven by the support plate 3 to approach the coupler. When the coupler is at the center of the two-jaw chuck 601, the user can tighten the bolt assembly 1 to limit the movement of the support plate 3. Then, the user tightens the claw block 603 by tightening the helical tooth rod 605 to clamp the coupler. After rotating the rocker arm 503 to push the coupler, the user reverses the rocker arm 503 to complete the disassembly of the coupler.
