detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figures 1-5, the utility model provides a technical solution: a steel box girder provided with an anti-slip hoisting structure, and a deep hole 2 is opened inside the beam body 1;

A steel box girder provided with an anti-slip hoisting structure, comprising:

Movable block 4, the front end of movable block 4 is provided with the through hole 6 that passes through for steel rope, and the surface of movable block 4 fits with the inner wall of beam body 1, and the inside of beam body 1 offers and offers chute 8, and The movable blocks 4 are distributed symmetrically about the center of the beam body 1;

The clamping block 11, the side of the clamping block 11 is fixedly installed with the overlapping block 12 corresponding to the deep hole 2, and the clamping block 11 corresponds to the movable block 4 one by one.

The surface of the beam body 1 is provided with a deep groove 3 corresponding to the movable block 4 , and the upper surface of the movable block 4 is fixedly mounted with a slider 5 corresponding to the chute 8 .

The upper surface of the slider 5 is provided with a locking groove 7 corresponding to the clamping block 11 , and the side of the slider 5 is fixedly installed with a first spring 9 which plays an elastic return function.

When being used, when hoisting is required, the movable block 4 is first pulled to move the movable block 4 to the outside of the deep groove 3, at this time the slider 5 slides inside the chute 8, and the first spring 9 is pulled by the slider 5 at this time When the slider 5 moves to the clamping block 11, the clamping block 11 is squeezed by the slider 5, and the clamping block 11 moves to the inside of the indented groove 13.
