[0019] 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. Example
[0020] The gearbox assembly platform used in existing technology requires flexible height adjustment during assembly and operator operation to meet specific needs. Furthermore, stability must be ensured during adjustment to maintain assembly precision. Please refer to [reference needed]. Figures 1-3The embodiment provides an easily adjustable gearbox assembly platform for rail transit, which can effectively improve the flexibility of platform height adjustment and ensure stability during the adjustment process. The easily adjustable gearbox assembly platform for rail transit includes a workbench 1, an adjustment device installed at the bottom of the workbench 1, clamping devices installed at the left and right ends of the middle of the top surface of the workbench 1, and an auxiliary device installed near the back of the top surface of the workbench 1.
[0021] The adjustment device includes a hydraulic adjustment structure and a lifting connection structure, with the hydraulic adjustment structure installed in the middle of the lifting connection structure. The hydraulic adjustment structure includes an asynchronous motor 102, with a transmission component 103 connected to the output end of the asynchronous motor 102. An adjustment rod 104 is installed in the middle of the transmission component 103, and a connecting cylinder 105 is connected to the bottom of the outer surface of the adjustment rod 104. A pressure plate 106 is connected to the bottom of the connecting cylinder 105, and limit rods 107 are connected to the left and right sides of the pressure plate 106. The lifting connection structure includes a liquid tank 101, with connecting pipes 108 connected to the middle of the left and right sides of the liquid tank 101 near the bottom. A telescopic rod 109 is connected to the end of the connecting pipe 108 away from the liquid tank 101, and an anti-slip seat 110 is fixedly installed at the bottom of the telescopic rod 109.
[0022] The asynchronous motor 102 is detachably installed on the top surface of the liquid tank 101. The outer surface of the adjusting rod 104 is connected to the middle of the top surface of the liquid tank 101 through a bearing. The outer surface of the pressure plate 106 is slidably and sealed to the inner wall of the liquid tank 101. The left and right sides of the pressure plate 106 are slidably and sealed to the inner wall of the convex groove in the middle of the limiting rod 107. The bottom end of the outer surface of the adjusting rod 104 is threaded to the inside of the connecting cylinder 105. The top end of the telescopic rod 109 is connected to the four corners of the bottom surface of the worktable 1.
[0023] By adjusting the device, the asynchronous motor 102 is started to drive the transmission component 103 and the adjusting rod 104 to perform transmission adjustment, thereby using the pressure plate 106 to push and adjust the hydraulic oil, thereby driving the telescopic rod 109 to adjust the height of the worktable 1.
[0024] When adjusting the height of the workbench 1, the asynchronous motor 102 is started to drive the transmission component 103. The output end of the asynchronous motor 102 drives the worm to rotate. The outer surface of the worm meshes with the outer surface of the worm wheel. The worm wheel drives the adjusting rod 104 to rotate. The bottom end of the adjusting rod 104 is threadedly connected to the inside of the connecting cylinder 105, thereby driving the pressure plate 106 to squeeze the hydraulic oil inside the liquid tank 101. During the sliding and squeezing process of the pressure plate 106, the pressure plate 106 and the middle of the limit rod 107 are sealed and slide, thereby ensuring the stability of the pressure plate 106 during displacement. The hydraulic oil enters the telescopic rod 109 through the connecting pipe 108, causing the telescopic rod 109 to extend and retract, thereby driving the workbench 1 to adjust its height. This achieves stable and flexible adjustment of the height of the workbench 1. Example
[0025] Based on implementation one, existing technologies also have the problem of stably clamping the gearbox to ensure stability during assembly, while also facilitating the quick removal of assembled parts. Please refer to... Figures 4-5 This embodiment provides an easily adjustable gearbox assembly platform for rail transit, which effectively solves the stability problem of the gearbox during assembly and facilitates quick handling of assembled parts. The easily adjustable gearbox assembly platform includes a clamping device comprising a fixed plate 201. An electric push rod 202 is mounted in the middle of the fixed plate 201, and a locking block 203 is mounted at the output end of the electric push rod 202. A clamping block 204 is mounted in the middle of the locking block 203. The bottom of the fixed plate 201 is fixedly connected to the left and right ends of the middle of the top surface of the workbench 1. The clamping block 204 and the locking block 203 have a convex groove in the middle for internal engagement.
[0026] The auxiliary device includes a parts box 301, with an observation window 302 installed in the center of the front of the parts box 301. A spring 303 is installed in the center of the bottom surface inside the parts box 301, and a placement plate 304 is connected to the top of the spring 303. The bottom of the parts box 301 is fixedly connected to the top surface of the workbench 1, the bottom end of the spring 303 is fixedly connected to the bottom surface inside the parts box 301, and the outer surface of the placement plate 304 is slidably connected to the inner wall of the parts box 301.
[0027] By using the clamping device and auxiliary device, the detachable connection between the card block 203 and the clamping block 204 facilitates the clamping and fixing of different models of gearboxes, thereby achieving stable assembly. At the same time, the spring 303 and the placement plate 304 facilitate the removal of parts.
[0028] During gearbox assembly, the electric push rod 202 is activated to move the locking block 203 and clamping block 204. The two clamping blocks 204 clamp and fix the gearbox, ensuring its stability during assembly. The locking block 203 and clamping block 204 are secured with bolts, facilitating clamping and fixing of gearboxes of various sizes. When parts are placed inside the parts box 301, the weight of the parts compresses the spring 303. As parts are removed sequentially, the spring 303's deformation and rebound force gradually raises the placement plate 304, facilitating the sequential removal of remaining parts. The observation window 302 allows for monitoring of the remaining parts.
