[0038] With reference to Figure 3 and Figure 4 , the stable protection mechanism 3 comprises a multi-end rotating shaft 31 and a protection structure 32. The multi-end rotating shaft 31 is used for linking the platform support 11 and the protection structure 32, specifically, the multi-end rotating shaft 31 is rotationally connected to the booster push plate 22, the multi-end rotating shaft 31 has a limiting arm 311 and a cooperating arm 312, in the initial state, the limiting arm 311 is arranged in the platform mechanism 1 and located between the support rods 111, the cooperating arm 312 is used for driving the protection structure 32, the limiting arm 311 is located below the protection structure 32, a reset torsion spring 313 is arranged between the multi-end rotating shaft 31 and the booster push plate 22, under the action of the reset torsion spring 313, the multi-end rotating shaft 31 is in the initial position.

[0039] The protection structure 32 comprises a push block 321 slidingly connected with the jacking mechanism 2 and a holding assembly 322 slidingly connected with the push block 321, the holding assembly 322 is located on both sides of the platform mechanism 1. The push block 321 is used for driving the holding assembly 322, when the platform mechanism 1 is in the jacking state, the push block 321 drives the holding assembly 322 to be separated from the platform mechanism 1; when the platform mechanism 1 is in the stable state, the platform mechanism 1 contacts with the limiting arm 311, and the push block 321 drives the holding assembly 322 to abut against the platform mechanism 1. More specifically, a sliding cavity 221 is arranged in the booster push plate 22, the push block 321 is slidingly connected with the booster push plate 22 in the sliding cavity 221, and a plurality of springs are arranged on the top of the sliding cavity 221, that is, the push block 321 can reciprocate along the height direction of the booster push plate 22.

[0040] The holding assembly 322 comprises holding clamping plates 3221 connected to both sides of the assisting push plate 22 through sliding connection, and the holding clamping plates 3221 are provided with arc-shaped grooves 3222 for matching the push block 321; correspondingly, the push block 321 is provided with adaptive ends 3211 on both sides in the width direction, and the assisting push plate 22 is provided with displacement sliding grooves 222 on both sides in the width direction; the adaptive ends 3211 are arranged in the displacement sliding grooves 222 and are connected to the holding clamping plates 3221 through sliding connection. When the platform support 11 is completed by the jacking, the jacking mechanism 2 is slowly unloaded to make the platform support 11 enter a stable state, and the platform support 11 will move downward by a certain distance due to its own gravity; at this time, one of the support rods 111 will abut against the limiting arm 311 and drive the limiting arm 311 to rotate downward, the limiting arm 311 rotating downward drives the matching arm 312 to rotate upward, the matching arm 312 rotating upward drives the push block 321 to slide upward in the sliding cavity 221, and the push block 321 sliding upward drives the holding clamping plates 3221 on both sides to move away from the platform support 11 through the arc-shaped grooves 3222; the holding clamping plates 3221 have holding ends, and the holding ends of the holding clamping plates 3221 finally hold the platform support 11 on both sides to limit and further support the platform support 11 on both sides.

[0042] Compared with the traditional protection mode of manually performing additional stabilization operation, the present application not only omits this step to make the construction process more smooth and efficient, but also reduces the safety hazards caused by human high-altitude operation through the use of the platform mechanism 1 to realize automatic mechanical control, effectively prolongs the service life of the equipment and improves the reliability of the overall structure.

When the push arm 23 cooperates with the jacking support rod 111, the lower half self-locking assembly cooperates with the upper half self-locking assembly to form a self-locking groove covering the support rod 111.

[0045] When the driving structure 24 drives the assisted push plate 22 to rise, the rising assisted push plate 22 drives the push arm 23 to rotate and abut below the support rod 111. At this time, the lower half self-locking assembly contacts the support rod 111, the pressing spring 411 cooperates with the telescopic rod 412 and the buffer spring 413 after contacting the support rod 111, the sliding tooth plate 4112 moves downward, the meshing gear 415 fixed on the push arm 23 rotates under the driving of the sliding tooth plate 4112, thereby driving the arc-shaped clamping plate 414 to move in the direction of the pressing spring 411, and finally the arc-shaped clamping plate 414 cooperates with the pressing spring 411 to cover the support rod. During the jacking process, the contact area of the push arm 23 and the support rod can be effectively increased. By setting the self-locking structure 41, on the one hand, the stability of the jacking process can be ensured, and the stability of the platform mechanism 1 can be ensured even if affected by environmental wind force; on the other hand, the mechanical transmission mode of the sliding tooth plate 4112 and the meshing gear 415 can fully utilize the stroke of the push arm 23 to act, thereby ensuring the reliability, accuracy and service life of the transmission structure.
