Lifting station device for lifting overweight cable of cable-stayed bridge

Abstract

The invention discloses a lifting station device for lifting an overweight cable of a cable-stayed bridge, and relates to the technical field of large-span bridge construction. The lifting station device comprises a supporting truss, the supporting truss is fixed on a steel box girder through a plurality of supporting leg mechanisms, and the lifting station device further comprises a lifting mechanism and an embedded anchoring mechanism; the front end of the supporting truss exceeds the front end of the steel box girder; the lifting mechanism is movably arranged on the top face of the supporting truss and used for lifting coiled cables; and the two ends of the embedded anchoring mechanism are connected with the supporting truss and the steel box girder correspondingly and used for bearing anchoring stress of the whole device. The lifting station device is directly mounted on a bridge surface after construction of the bridge surface is completed, and is used for lifting the cable. The whole structure can be assembled into a whole and then hoisted by a tower crane, and can also be assembled at the top of a tower. By means of the cable lifting device, the overweight cable can be effectively and stably lifted, and the high-altitude operation risk of the tower crane is reduced; and mounting, dismounting and reutilization are facilitated.

Description

technical field [0001] The invention relates to the technical field of long-span bridge construction, in particular to a hoisting station device for hoisting a cable-stayed bridge with super-heavy cables. Background technique [0002] At present, with the rapid development of my country's economy, the status of traffic engineering construction is particularly important; when the road crosses large rivers, rivers, lakes, seas, railways, valleys and other areas with complex geological conditions or navigation limit requirements, the cable-stayed bridge As a bridge with large spanning capacity and low investment cost and construction difficulty, it is more and more applied to the current road construction, especially in recent years with the development of science and technology, a large number of cable-stayed bridges It is adopted by road, railway, and road-rail bridges, and the span is getting larger and larger. Under such background, many problems are often encountered during...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the defects existing in the prior art, the object of the present invention is to provide a lifting station for cable-stayed bridge cable-lifting for various unfavorable combinations of the tower crane itself, including problems such as the lifting height and the weight of the lifting cables. This device not only considers the stability of the hoisting super-heavy cable, but also helps to place the cable on the cable reel smoothly, paving the way for the subsequent cable deployment
