[0028] The reinforcement device includes at least two lifting ears 31 and at least two steel wire ropes 32. The at least two lifting ears 31 are spaced apart and fixed to the structural steel beam 3 at the bottom of the upper floor slab 2. The at least two steel wire ropes 32 are symmetrically arranged on both sides of the cantilever frame along the axis. One end of the steel wire rope 32 is connected to the lifting ear 31, and the other end is connected to the cantilever end of the main beam 11.

[0029] The self-movable cantilevered unloading platform of the utility model comprises a cantilevered frame with one end cantilevered and the other end anchored to the edge of the current construction layer floor 1, a unloading platform 20 arranged on the top of the cantilevered frame and capable of sliding horizontally along the roller 21 groove of its main beam 11, and a reinforcement device for connecting the cantilevered end of the cantilevered frame to the bottom structural steel beam 3 of the upper floor. Since the roller 21 at the bottom of the unloading platform 20 can slide horizontally along the roller 21 groove of the cantilevered frame, the material can be transported to the room through the unloading platform 20, thereby transferring the material loading and unloading work to the room, which greatly reduces the pressure on the cantilevered platform, ensures the safety of material loading and unloading construction, and improves the carrying capacity of the unloading platform 20; the cantilevered end of the cantilevered frame is connected to the lifting ear 31 fixed to the bottom structural steel beam 3 of the upper floor through a steel wire rope 32, which improves the structural stability of the cantilevered frame without causing damage to the existing building structure, and further ensures the construction safety of the unloading platform 20.

[0030] like Figure 1 and Figure 2 As shown, the platform body of the unloading platform 20 is composed of a frame formed by welding square steel pipes arranged in a criss-cross pattern, and a steel plate covering and connected to the top of the frame.

The lifting lug 31 is made of ordinary steel plate.

[0034] like Figure 1 and Figure 2 As shown, the self-movable cantilever unloading platform includes four steel wire ropes 32, and the four steel wire ropes 32 are symmetrically arranged on both sides of the cantilever frame along the axis thereof, and the two steel wire ropes 32 on the same side are spaced apart along the length extension direction of the main beam 11 to avoid the entire cantilever platform from losing balance due to the breakage of the main force-bearing steel wire ropes 32.

[0035] Please continue to refer to Figure 1 The angle between the steel wire rope 32 and the cantilever frame is 45° to 60°, which ensures the safety of the cantilever frame. Furthermore, a cushion layer is added at the position where the steel wire rope 32 contacts the through hole of the ear plate 312 to reduce the wear of the steel wire rope 32. In this embodiment, the cushion layer can be made of automobile tires.

[0036] like Figure 5 As shown, the reinforcement device also includes at least two anchor bars 33. The cantilevered ends of the two main beams 11 located on the outside of the cantilever frame are respectively connected to an anchor bar 33. The anchor bar 33 is U-shaped, and its open end is welded to the main beam 11. The end of the steel wire rope 32 passes through the anchor bar 33 and is locked and fixed, so that the cantilevered end of the cantilever frame can be stably connected to the ear 31 of the upper floor structure steel beam 3 through the steel wire rope 32.
