When the steel formwork is lifted, the fixed plate is locked to the lifting hole of the steel formwork with the fasteners, and the external mechanism lifts the steel formwork with the cable fixed at the cable hanging ring. This utility model solves the problem that the steel formwork is often tied with steel cables when it is lifted, but this can easily cause the steel cables to exert excessive pressure on the local part of the steel formwork, making it easy for the steel formwork to slip due to deformation and cause danger.

[0030] The working principle of the above embodiment is:

[0031] (1) First, place the steel formwork to be hoisted on the support plate 3, then turn on the motor 401, the output shaft of the motor 401 drives the rotating rod 402 to rotate, the rotating rod 402 drives the winding roller 403 to rotate, the winding roller 403 winds up the traction rope 404, the winding of the traction rope 404 drives the support plate 3 to rise, the support plate 3 drives the steel formwork to move, so that the support plate 3 and the hoisting plate 1 clamp and fix the steel formwork, improve the stability of the steel formwork, after the steel formwork is fixed, lift the connecting ring 409, the connecting ring 409 drives The second hinged seat 408 moves, and the movement of the second hinged seat 408 drives the second protective plate 407 and the first protective plate 406 to rotate, so that the second protective plate 407 and the first protective plate 406 are unfolded, and the iron sheet 410 on the connecting ring 409 is moved to the magnetic ring 411, and the magnetic ring 411 adsorbs the iron sheet 410 to stabilize the positions of the first protective plate 406 and the second protective plate 407, thereby protecting the surrounding of the steel formwork to avoid the steel formwork from falling due to accidents during the lifting process, thereby improving safety.

[0032] (2) After the steel formwork is fixed and protected, the rope buckle of the crane is inserted into the connecting frame 501. The rope buckle pushes the stopper 503, causing the stopper 503 to rotate and open the connecting frame 501, allowing the rope buckle to enter the connecting frame 501. After entering, the torsion spring 504 rebounds the stopper 503 to the limit plate 505 to prevent the rope buckle from escaping from the connecting frame 501. Then, the rope buckle is moved to the first clamping seat 506, and then the turning handle 508 is turned. The turning handle 508 drives the threaded rod 507 to rotate. The threaded rod 507 rotates and moves on the connecting frame 501. The movement of the threaded rod 507 drives the second clamping seat 509 to move. The second clamping seat 509 is moved to the first clamping seat 506, so that the rope buckle is located between the first clamping seat 506 and the second clamping seat 509, so as to prevent the rope buckle from randomly deviating on the inner side of the connecting frame 501 and affecting the balance of the lifting.
