Auxiliary positioning device for installation of prefabricated piers and columns of large-span prefabricated high-speed railway bridges

Abstract

The invention relates to the technical field of high-speed railway bridge construction, in particular to an auxiliary positioning device for the installation of prefabricated piers of large-span prefabricated high-speed railway bridges, comprising a camera, a main cable, a fastening frame and a console. The beneficial effects are as follows: the device can display the movement and the docking status of the bottom of the prefabricated pier to the crane operator in real time through the camera installed on the installation cylinder, thereby effectively replacing the remote observation by the operator and the way of relaying after observation by other personnel. , which can more intuitively and accurately understand the movement and docking status of the bottom of the prefabricated pier, which facilitates the operator to perform faster and more accurate operations, and can effectively shorten the operation time and reduce the occurrence of operation accidents. The combined form of the connecting frame, the surface connecting frame and the clamping seat can quickly realize disassembly and installation, and the device can also be reused, so the construction period can be greatly shortened and the construction efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of high-speed railway bridge construction, in particular to an auxiliary positioning device for installing prefabricated piers of large-span prefabricated high-speed railway bridges. Background technique [0002] With the rapid development of high-speed rail transportation in my country, more and more prefabricated components are used to build high-speed rail bridges. Among them, the prefabricated piers of high-speed rail bridges need to be hoisted during installation. During hoisting, external hoists and other hoisting equipment are used to hoist the prefabricated piers to the designated position, and then the reinforcement holes set at the bottom of the prefabricated piers and the steel bars reserved in the corresponding area are carried out. Align the plug to complete the hoisting operation. [0003] However, because the hoisting equipment is far away from the prefabricated pier, it is difficult for the ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an auxiliary positioning device for the installation of prefabricated pier columns of long-span prefabricated high-speed railway bridges, so as to solve the problem that the hoisting operators cannot directly observe the bottom movement and docking status of prefabricated pier columns in real time, which leads to docking positioning. Difficult operation, long construction time, etc.
