The translation structure 30 is directly contacted with the ground and mainly subjected to extrusion force, and the requirement on the material is looser, so that the 45 steel with general performance is selected; and a height-adjustable foot pad can be arranged below the bottom of the translation structure 30 to improve the stability of the platform.
In addition, the translation structure 30 is designed into a cover type through the additionally arranged cover body 37, one of the reasons is that the translation structure 30 and the swing mechanism can be protected, the device can be effectively prevented from being placed into the placing layer by a person mistakenly when the device works, and the whole device is more attractive. The three-side packaging structure is designed, and the side without packaging is convenient for the upper layer structure to extend out during translation. Holes are reserved on the bottom plate of the cover body 37, devices such as the stabilizing handrail 40 can be directly inserted and fixed, and labor is saved during installation. The whole equipment occupies a floor area of 120cm multiplied by 120cm and needs to have a translation stroke of +/-20 cm and a swing angle of +/-10 degrees. Reduce the size of last two-layer platform and handle swing structure 20 to avoid equipment cover formula bottom plate to interfere with last two-layer platform flat board in the motion process, guarantee that each mechanism places the layer and normally works.
