Combined hoisting equipment and hoisting method for bridge engineering construction

Abstract

The invention provides combined hoisting equipment and a hoisting method for bridge engineering construction. The combined hoisting equipment for bridge engineering construction comprise a bridge body, a hoisting mechanism, and a reinforcing mechanism, wherein the reinforcing mechanism comprises a rope, a supporting plate, a variable frequency motor, a fixing shaft, rolling wheels and grooves, the supporting plate is installed at the bottom end of the hoisting mechanism, the rolling wheels are rotatably connected into the supporting plate at equal intervals, the side walls of the rolling wheels are fixedly connected with the fixing shaft, the variable frequency motor is installed on the side wall of the supporting plate and connected with the fixing shaft, the rope is wound on the side walls of the rolling wheels, the grooves are formed in the bottom face of the supporting plate at equal intervals, the rope is connected into the grooves in a sliding mode, and the rope abuts against the bottom face of the bridge body; and the equipment further comprises a connection mechanism, a support mechanism, a limiting mechanism, and a fixing mechanism. The combined hoisting equipment and the hoisting method for bridge engineering construction provided by the invention have the advantage of rapidly hoisting a prefabricated bridge.

Description

technical field [0001] The invention relates to the technical field of bridge engineering construction, in particular to a combined hoisting device and hoisting method for bridge engineering construction. Background technique [0002] A bridge refers to a building built for roads to cross natural or artificial obstacles. It is erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. A bridge generally consists of a superstructure, a substructure and ancillary structures. The superstructure mainly refers to the bridge span structure and support system; the substructure includes abutments, piers and foundations; , diversion engineering, etc. According to the structural system of bridges, there are four basic systems: girder bridge, arch bridge, rigid frame bridge, and suspension cable bearing (suspension bridge, cable-stayed bridge). [0003] During bridge construction, steel wire mesh is used to wrap the bottom of the prefabricated bridge first,...

AI Technical Summary

Problems solved by technology

[0003] During bridge construction, steel wire mesh is used to wrap the bottom of the prefabricated bridge first, and then a crane is used to hoist the prefabricated bridge to the installation position. Difficulty, and it is difficult to move the steel mesh covered prefabricated bridge to a more suitable position
