Description

Bridge expansion joint construction lifting device

Technical Field

The invention belongs to the technical field of bridge construction in highways and municipal engineering, and particularly relates to a hoisting tool for bridge expansion joint construction.

Background

In the bridge construction process, in order to meet the requirement of bridge deck deformation, expansion joints are usually arranged between two beam ends, between the beam ends and an abutment or at the hinged position of a bridge; the expansion joint is required to freely expand and contract in two directions parallel to and perpendicular to the axis of the bridge, and is firm and reliable, when a vehicle runs, the vehicle is smooth without sudden jump and noise, and the expansion joint of the bridge is used for adjusting the displacement and connection between upper structures caused by vehicle load and bridge building materials. In particular, once the telescopic device of the skew bridge is damaged, the speed, the comfort and the safety of the vehicle can be seriously influenced, and even the vehicle safety accident can be caused. Because the expansion joint dead weight is great, the fine place of construction stage is difficult to adjust, and bridge expansion joint of construction at present stage mainly uses the truck crane to carry out the installation construction, and its position and ride comfort degree are difficult for adjusting, cause the flexible seam smoothness after the construction relatively poor, produce a large amount of jump car phenomena. The invention provides a lifting tool for bridge expansion joint construction, and aims to solve the problems of lifting and accurate fine adjustment in the installation process of expansion joints.

Disclosure of Invention

Aiming at the technical problems in the prior art, the invention aims to provide a hoisting tool for bridge expansion joint construction, and in order to achieve the purpose, the technical scheme adopted by the invention is as follows:
