Abstract

The invention provides a lifting hook for lifting a box girder reinforcement cage, which comprises a truss and a plurality of suspension assemblies, the plurality of suspension assemblies are arranged at the bottom of the truss at intervals, each suspension assembly comprises a left suspension arm and a right suspension arm, and the left suspension arms and the right suspension arms are symmetrically arranged at the bottom of the truss. Movable suspension heads are arranged on the left suspension arm and the right suspension arm, each suspension head comprises a mounting plate, a front lifting hook, a rear lifting hook, a first gear, a second gear, a driving gear, a first rotating shaft, a second rotating shaft and a driving rotating shaft, and the front lifting hook and the rear lifting hook are arranged on the two sides of the mounting plate respectively. The problems that during transmission hoisting of the reinforcement cage, the reinforcement cage is prone to deformation, the reinforcement cage structure is affected, connection is complex and slow, the error-tolerant rate is low, and the working efficiency is low are solved.

Description

technical field [0001] The invention relates to the technical field of box girder steel reinforcement frame hoisting, in particular to a hook for box girder steel reinforcement frame hoisting. Background technique [0002] Box girder, a kind of beam in bridge engineering, is hollow inside, with flanges on both sides of the upper part, similar to a box, hence the name. First, bind the processed steel skeleton on the tire mold of the independent site, set up corrugated pipes for forming the prestressed rib channel, and then install the special steel template for the beam body, pour concrete and carry out maintenance, when the strength of the concrete meets the design requirements. The prestressed cables are threaded, and the prestressed tendons are tensioned and anchored in sequence, and then grouting and anchor sealing are performed to complete the prefabrication of the beam body. [0003] The box girder steel frame is mainly composed of a U-shaped bottom frame and a roof fr...
