Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example:

[0020] Please refer to Figures 1-3.

[0021] A simple high pier hanging basket formwork removal device includes a fixed frame 1, an H-shaped steel 2 is fixedly welded to the inner side of the fixed frame 1, a through-hole jack 3 is fixedly installed inside the H-shaped steel 2, two tripods are fixedly welded to the outer wall of the H-shaped steel 2, an upper clamp 5 is movably connected to the output end of the through-hole jack 3, four first clamping plates are movably inserted inside the upper clamp 5, two steel wire ropes 7 are movably connected to the inner sides of the four first clamping plates, two second clamping plates 8 are movably connected to the outer walls of the two steel wire ropes 7, a lower clamp 9 is provided on the outer walls of the two steel wire ropes 7, and a pad 10 is movably connected to the top outer wall of the lower clamp 9;

[0022] On the bridge deck and on the front top beam of the hanging basket, one 75T through-hole jack 3 is preset corresponding to the four corners of the bottom basket. The bottom formwork system of the hanging basket is removed. After the fixed frame 1 is placed stably, two steel wire ropes 7 are passed down to the bottom beam of the bottom basket respectively. The lower clamp 9 and pad 10 are installed at the end of the steel wire rope 7 and an extrusion anchor head is made. It is fixed under the bottom beam so that the pad 10 can hang the bottom beam. After the four corners are fixed, the upper clamp 5 is used to fix the steel wire rope 7 above the through-hole jack 3, and the outer mold is lowered through the fall chain so that the outer sliding beam falls on the front and rear bottom beams. The outer mold is welded to the outer sliding beam, and then the outer sliding beam is welded to the bottom beam and fixed with channel steel. Before lowering, oil the through-hole jack 3, push out the inner core, and install the through-hole jack. 3. Fix the clamp 5 and wire rope 7. Then loosen the fall chains of the four corner beams at the same time to make the wire rope 7 stressed and form a system conversion. Adjust the through-hole jack 3 to make the four corners close to horizontal. After the four corner wire ropes 7 are fully stressed, let them stand for 30 minutes for pre-hanging. After 30 minutes, if there is no abnormality at each lifting point, release the fall chain and gradually lower the bottom basket and side formwork to the ground under the bridge through the contraction of the through-hole jack 3. Then dismantle and transport them away. When lowering, the four through-hole jacks 3 must be carried out synchronously, and the stroke range of each through-hole jack 3 must be accurately controlled by markings to ensure that the bottom formwork system is balanced during the lowering process. When the system is converted, each lifting point is tested by pre-hanging to ensure that the lifting point is firm and safe. Two wire ropes 7 are used at each lifting point to prevent one of them from breaking and causing an accident.
