Detailed Implementation

[0023] 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 (for ease of description and understanding, hereinafter referred to as...). Figure 4 (The above is described above). Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Please see Figure 1-8 The present invention provides a technical solution: a skid with a movable step, including a skid 1, on which crossbeams 3 are evenly distributed, and a horizontally movable step assembly 2 is provided at one end of the skid 1. The step assembly 2 includes a pedal assembly 21, a mounting base assembly 22 and a locking mechanism 23.

[0025] The pedal assembly 21 is disposed above the skid 1 and includes a pedal 211 for supporting the worker to stand.

[0026] Mounting bracket assembly 22 is symmetrically arranged at the lower end of pedal 211, including base plate 221, vertical plate 222, fixing plate 224 and U-shaped plate 227. Base plate 221 contacts the upper surface of skid 1. Vertical plate 222 is vertically fixed to the upper surface of base plate 221. Fixing plate 224 and U-shaped plate 227 are respectively fixed to the upper surface of base plate 221, and both are located on both sides of vertical plate 222. Fixing plate 224 faces the outside of skid 1. Fixing plate 224 is provided with starting position slot 225 and ending position slot 226. When pedal 211 is not extended, locking pin 236 in locking mechanism 23 is located in starting position slot 225. When pedal 211 needs to be extended, locking pin 236 is located in ending position slot 226, which ensures the stability of pedal 211 and limits the extension length of pedal 211.

[0027] The open end of the U-shaped plate 227 faces the inside of the skid 1. The pedal assembly 21 moves inside the U-shaped plate 227. The base plate 221 is provided with a through hole 228. A clamp 4 passes through the through hole 228. The clamp 4 fixes the crossbeam 3 to the base plate 221. The clamp 4 has a U-shaped structure. The outer sides of the two cylinders at the open end of the clamp 4 are provided with threads. After the bottom of the open end of the clamp 4 contacts the bottom of the crossbeam 3, the two cylinders at its upper end pass through the through hole 228 and are tightened with nuts, which facilitates the installation and disassembly of the entire platform assembly 2.

[0028] The locking mechanism 23 is symmetrically arranged at the lower end of the pedal 211 and located on one side of the mounting base assembly 22. The locking mechanism 23 includes a mounting plate 231, a connecting plate 232, a rotating shaft 233, a torsion spring 234, a locking pin 236, a dial wheel 237, and a rotating arm 238. The mounting plate 231 is connected to the lower surface of the pedal 211 by bolts. The connecting plate 232 is symmetrically fixed to the lower surface of the mounting plate 231. The rotating shaft 233 is rotatably connected between the two connecting plates 232. The rotating arm 238 is fixed to the outer side of the rotating shaft 233. The torsion spring 234 is arranged between the rotating shaft 233 and the rotating arm 238. The locking pin 236 is fixed to one side of the rotating arm 238. 6. The starting position slot 225 and the ending position slot 226 on the fixed plate 224 are engaged with the dial wheel 237, which is fixed on the other side of the rotating arm 238. When the skid 1 transports a long vehicle, the skid 1 moves to the platform opening station. At this time, the dial wheel 237 strikes the lever set on the platform opening station. Under the action of the lever, the dial wheel 237 is lifted and the self-locking state is released. The skid 1 continues to move forward. At this time, the pedal 211 moves backward relative to the skid 1 until the locking pin 236 moves to the ending position slot 226. Under the action of the torsion spring 234, the locking pin 236 is locked into the ending position slot 226, and the pedal 211 is fully opened, making it convenient for workers to stand on the pedal 211 to work.

[0029] Furthermore, to facilitate the smooth and straight horizontal movement of the pedal 211 along the mounting bracket assembly 22, four guide wheel assemblies are provided at the lower end of the pedal 211. The four guide wheel assemblies are symmetrically arranged on both sides of the lower surface of the pedal 211, with two guide wheel assemblies on each side. The guide wheel assembly includes a vertical guide wheel 212 and a horizontal guide wheel 213. The horizontal guide wheel 213 is located on one side of the vertical guide wheel 212. The vertical guide wheel 212 rolls in the groove of the U-shaped plate 227. The vertical guide wheel 212 contacts the upper and lower surfaces of the groove of the U-shaped plate 227, and the horizontal guide wheel 212 contacts the inner wall of the U-shaped plate 227. This restricts the movement trajectory of the pedal 211 in both the vertical and horizontal directions, ensuring its linearity and stability.

[0030] To improve the connection strength between the base plate 221 and the vertical plate 222, reinforcing ribs 223 are evenly distributed on one side between the base plate 221 and the vertical plate 222.

[0031] To facilitate the installation of the torsion spring 234, a short post 235 is provided on one side of the rotating arm 238. One end of the torsion spring 234 is connected to the rotating shaft 233, and the other end of the torsion spring 234 is connected to the short post 235.

[0032] To improve the stability of the connection between the clamp 4 and the mounting base assembly 22, each mounting base assembly 22 is connected to the crossbeam 3 on the skid 1 by at least two clamps 4.

[0033] In use: When the skid 1 is equipped with a short vehicle model, the worker can work by standing on the pedal 211; when the skid 1 is equipped with a long vehicle model, it needs to pass through the platform opening station. At this time, the dial wheel 237 in the locking mechanism 23 will hit the lever on the platform opening station. Under the action of the lever, the locking pin 236 is lifted, so that the locking pin 236 is disengaged from the starting position slot 225. As the skid 1 continues to move forward, the platform assembly 2 moves relative to the mounting base assembly 22. The locking mechanism 23 moves together with the pedal 211 until the locking pin 236 reaches the ending position slot 226 of the fixing plate 224. Under the action of the restoring force of the torsion spring 234, the locking pin 236 is locked in the ending position slot 226. At this time, the pedal 211 is fully opened and extends one end of the skid 1, which is convenient for the worker to stand and work.

[0034] This utility model allows the step assembly 2 to be opened and closed according to different vehicle models, providing standing space for workers; a locking mechanism is set to unlock and self-lock the pedal 211, ensuring the stability of the pedal 211 after it is extended.

[0035] The parts of the utility model not described in detail are prior art. Although embodiments of the utility model 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 utility model. The scope of the utility model is defined by the appended claims and their equivalents.
