Document Type and Number:
WIPO Patent Application WO/2022/262197
Kind Code:
A1
Abstract:
A steel box girder provided with an anti-skid hoisting structure. The interior of a girder body (1) is provided with a deep hole (2). The steel box girder comprises movable blocks (4), wherein a front end of each movable block (4) is provided with a through hole (6) for allowing a steel rope to pass through, a surface of each movable block (4) is attached to an inner wall of the girder body (1), the interior of the girder body (1) is provided with a sliding groove (8), and the movable blocks (4) are symmetrically distributed with regard to the center of the girder body (1); and clamping blocks (11), wherein a side face of each clamping block (11) is fixedly provided with a lap joint block (12) corresponding to the deep hole (2), and the clamping blocks (11) correspond to the movable blocks (4) on a one-to-one basis. When the steel box girder provided with the anti-skid hoisting structure is used and needs to be hoisted, the movable blocks (4) are pulled first, such that the movable blocks (4) move towards an outer side of a deep groove (3), at which time, a sliding block (5) slides in the sliding groove, and when the sliding block (5) moves to the positions of the clamping blocks (11), the clamping blocks (11) enter clamping grooves (7), and at this time, the movable blocks (4) and the girder body (1) are in a snap-fit state, and during operation, drawn steel ropes are inside the through holes (6), thereby facilitating hoisting work of the girder body (1).
