[0036] With reference to Figure 1 and Figure 6 The storage mechanism 3 comprises a storage box 301 fixedly connected to the top of the movable platform 1, the outer wall of the storage box 301 is rotatably connected with a cover plate 302, the cover plate 302 can be flipped open, and is in a horizontal state as a closed state, the inner wall of the cover plate 302 is elastically connected with an L plate 304 through a connecting spring 303, the side away from the connecting spring 303 of the L plate 304 is fixedly connected with a limiting block 305, the limiting block 305 has the functions of resetting and limiting through the elasticity of the connecting spring 303, and the bottom of the limiting block 305 is provided with an inclined surface, the inclined surface is arranged to facilitate closing the cover plate 302, the inner wall of the storage box 301 is provided with a square groove, the inclined surface of the limiting block 305 is inserted into the inner surface of the square groove, the two are inserted so that the cover plate 302 is in a horizontal state and cannot be opened upward, the limiting of the limiting block 305 needs to be removed, the outer wall of the L plate 304 is slidably connected to the inner wall of the cover plate 302, and the penetration facilitates manual movement of the L plate 304, the outer wall of the limiting block 305 penetrates and is slidably connected to the inner wall of the cover plate 302, and the penetration facilitates insertion and fixation with the square groove.

[0037] Working principle: when the need to move the movable platform 1, directly push the movable platform 1, the bottom of the moving wheel can make it easy to slide on the ground, quickly to the maintenance position, when the need to expand the area of movable platform 1, for maintenance personnel to provide more spacious work area, start the motor 201. The output end of the motor 201 rotates, driving the rotating plate 202 fixedly connected with it synchronous rotation. Because the rotating plate 202 inner wall rotatingly connected with the slider 203, and the slider 203 inner wall and the guide plate 204 outer wall slide fit, the guide plate 204 is fixedly connected with the extension plate 205, so the rotating plate 202 rotates, the slider 203 will slide on the guide plate 204, and then push the two groups of guide plate 204 to move outward, prompting the extension plate 205 to slide along the inner wall of the movable platform 1.

[0038] In the process of sliding the extension plate 205, the connecting plate 207 and the rack 208 fixedly connected with the front and rear ends will also move, the bottom of the rack 208 is engaged with the gear 209, the movement of the rack 208 drives the gear 209 to rotate, because the gear 209 is fixedly connected with the support leg 206, so the support leg 206 will also rotate. When the support leg 206 rotates, the rotating plate 210 fixedly connected with the side close to the extension plate 205 rotates synchronously. When the rotating plate 210 rotates one hundred and eighty degrees, it will contact with the connecting plate 207, thereby limiting the rotating plate 210 from continuing to rotate, ensuring that the support leg 206 can stably support the extension plate 205 after the extension plate 205 is expanded to the position, ensuring that the expanded movable platform 1 is stable in structure, and the bottom of the support leg 206 is provided with a roller after expansion, so as to not affect the overall movement.

[0039] The storage mechanism 3 is used for storing the maintenance tools. When the tool needs to be stored, the L plate 304 is moved to the right to release the limiting block 305 from the limiting position of the storage box 301, and then the cover plate 302 is turned up to open the storage box 301. After the tool is put into the storage box 301, the cover plate 302 is lowered. During the falling process of the cover plate 302, because the bottom of the limiting block 305 is provided with an inclined surface, when the inclined surface contacts with the square groove in the inner wall of the storage box 301, the L plate 304 will be extruded to slide in the inner wall of the cover plate 302, and the connecting spring 303 will be compressed. When the cover plate 302 is completely lowered to the horizontal state, the limiting block 305 is inserted into the square groove in the inner wall of the storage box 301 under the elastic restoring force of the connecting spring 303, so as to limit and fix the cover plate 302, prevent the cover plate 302 from being opened accidentally, and ensure the safety of tool storage.

[0040] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
