Anchor group device of large-sized cable hoisting system track cables

Abstract

The invention belongs to an anchor group device of large-sized cable hoisting system track cables. The anchor group device is composed of a support structure, cable hoisting system track cable anchor beam structures, a cable hoisting system track cable anchor beam adjustment structure and an anchor beam traction and fixing structure. Each cable hoisting system track cable anchor beam structure is composed of an anchor beam and a semi-circular saddle, the two cable hoisting system track cable anchor beam structures are located at the two ends of a transverse fixed beam respectively, the middle of the front end surface of each anchor beam is provided with a front reinforcing beam, the middle of the rear end surface of each anchor beam is provided with a rear reinforcing beam, cable-threading through holes are formed in the middles of the front reinforcing beams, rear reinforcing beams and anchor beams, the two semi-circular saddles are located on the two sides of a rear reinforcing beam of an anchor beam at one end respectively, and a loop formed by wrapping and fixing ends of all the cable hoisting system track cables is arranged on the anchor beams, the transverse fixed beam and the semi-circular saddles in a sleeved mode. By means of the anchor group device, the two ends of the cable hoisting system track cables can be effectively fixed, and the length of each cable hoisting system track cable can be effectively adjusted at any time; the anchor group device has the advantages of being simple in structure, flexible to operate, safe, convenient and fast to use, good in using effect, efficient, good in quality and capable of achieving fast construction.

Description

technical field [0001] The invention belongs to a large-scale cable suspension load-bearing cable group anchor device. Background technique [0002] At present, suspension bridges and cable-stayed bridges have been widely used in bridge construction. During construction, first set up two main cables on both sides of the suspension bridge and the cable-stayed bridge, and then fix the upper end of the sling on the main cable at a distance. The anchor boxes at both ends of the stiffening beam are integrated into one. And the main cable is made up of several large-scale cable suspension load-bearing cables (or load-bearing cables for short), and the two ends of each load-bearing cable are respectively positioned in the anchor base on the cement shore foundation. For example, the main span of Liujiaxia Suspension Bridge is 536 meters, and there are 65 pairs of slings in the middle of the span. The length of the cables varies from 48 meters to 2.2 meters. The stiffening girder ...

AI Technical Summary

Problems solved by technology

This traditional anchoring device cannot effectively adjust the length of each load-bearing cable, it is inconvenient to install and dismantle, the construction speed is slow, the construction period is long, the cable strength cannot reach the standard after the cable is fixed, the efficiency is low, and the quality is poor, which affects the progress of the project.
