Cable-releasing device for cable-stayed bridge construction and its application method

Abstract

The present invention relates to the technical field of cable-stayed bridge construction, in particular to a cable-staying device for cable-stayed bridge construction and a method for using the same. The outer right end of the device is slidingly connected with a zipper cover, and the outside of the zipper cover is fixedly connected with a cable, and the cable runs through the fixed frame, the bottom surface of the fixed frame is fixedly connected with a universal wheel, and the right side of the top surface of the fixed frame is fixedly connected There is a guide device, and the drag cable runs through the guide device. In the present invention, through the set threaded shaft and the block, this setting cooperates with the screw connection between the threaded shaft and the limit block, the elastic force of the first spring on the push plate, and the electric telescopic rod. The fixed connection with the sliding sleeve and the sliding connection between the zipper sleeve and the fixed block and the clamping block can quickly realize the loading, installation and disassembly of the zipper sleeve fixed with the cable when the device is used, and the operation is simple, convenient and fast , to ensure the safety of the staff.

Description

technical field [0001] The invention relates to the technical field of cable-stayed bridge construction, in particular to a cable-releasing device for cable-stayed bridge construction and an application method thereof. Background technique [0002] Cable-stayed bridge, also known as cable-stayed bridge, is a bridge in which the main girder is directly pulled on the bridge tower by many cables. The structural system can be regarded as a multi-span elastically supported continuous beam with cables instead of buttresses, which can reduce the bending moment in the beam body, reduce the height of the building, reduce the weight of the structure, and save materials. The cable-stayed bridge is mainly composed of cables With the continuous development of society, more and more cable-stayed bridges are manufactured, so the application of auxiliary equipment for cable-stayed bridge construction is increasing, and the types of auxiliary equipment are becoming more and more There are m...

[0002] Cable-stayed bridge, also known as cable-stayed bridge, is a bridge in which the main girder is directly pulled on the bridge tower by many cables. The structural system can be regarded as a multi-span elastically supported continuous beam with cables instead of buttresses, which can reduce the bending moment in the beam body, reduce the height of the building, reduce the weight of the structure, and save materials. The cable-stayed bridge is mainly composed of cables With the continuous development of society, more and more cable-stayed bridges are manufactured, so the application of auxiliary equipment for cable-stayed bridge construction is increasing, and the types of auxiliary equipment are becoming more and more There are more and more, but some deficiencies may exist in the cable-stayed cable-releasing device of part cable-stayed bridge construction, therefore, the demand for a kind of cable-stayed cable-release device and its application method for cable-stayed bridge construction is increasing day by day

[0003] In the field of cable-stayed bridge construction, the cable-releasing devices currently used for some cable-stayed bridge constructions are inconvenient for the installation and disassembly of the zipper sleeve, and the operation is time-consuming and laborious, and there is a certain threat to the safety of the staff. In order to prevent the zipper from slipping, the cable-releasing device of some cable-stayed bridges has poor drying effect and low drying efficiency, and cannot filter and absorb dust, foreign matter and moisture from the outside. , it is easy to increase the friction between the cables, resulting in the phenomenon of corrosion of the cables, and it also accelerates the wear of the cables when retracting and retracting, shortening the service life of the cables, and even the cables for some cable-stayed bridge construction. When the device retracts and retracts the cables, the cables cannot be evenly distributed on the outside of the zipper sleeve, so that the cables cannot be retracted and retracted accurately, and the cables cannot be tensioned according to the requirements, which affects the cable-stayed bridge. The normal construction of the cable-stayed bridge will also lead to wear and tear of the cable, which shortens the service life of the cable. Therefore, in view of the above problems, a cable-releasing device for cable-stayed bridge construction and its application method are proposed.
