Adjustable hoisting equipment for concrete cable-stayed bridge cable

Abstract

The invention discloses adjustable hoisting equipment for a concrete cable-stayed bridge cable, and relates to the technical field of bridge construction. The adjustable hoisting equipment comprises a fixed base, a sliding base is slidably connected to the inner wall of the fixed base, two racks are fixedly connected with the surface of the sliding base, a first connecting ring is fixedly connected with the left side face of the fixed base, a second connecting ring is fixedly connected with the left side face of the sliding base, a driving column is rotatably connected with the surface of the fixed base, a rotating plate is fixedly connected with the surface of the driving column, a driving rod is fixedly connected with the surface of the rotating plate, a transmission block is slidably connected with the inner wall of the driving rod, a first spring is fixedly connected with the surface of the transmission block, and the end of the first spring is fixedly connected with the surface of the rotating plate. According to the invention, through mutual cooperation of the structures, the effects of adjusting the cable force of the cable, being easy to use and saving the manufacturing cost are achieved, and the problems that when a jack is used for adjusting the cable force of the cable, use is complex, and resources are wasted are solved.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to an adjustable hoisting device for cables of a concrete cable-stayed bridge. Background technique [0002] A cable-stayed bridge is a bridge whose deck is suspended by cable-stayed cables, also known as a cable-stayed bridge. As a cable system, the cable-stayed bridge has a larger spanning capacity than the girder bridge, and is the most important type of long-span bridge. The cable between two suspension points that can bear the load is called a suspension cable. Each point in the suspension cable can only bear tension, and the tension at each point is along the tangential direction of the suspension cable at that point. [0003] At present, in the construction of cable-stayed bridges, most of them adopt the form of cable hoisting, in which the cables need to be temporarily buckled and hung during the hoisting process. The tension of the cables needs to be different...
