Fixing support for bridge detection equipment

Abstract

The invention relates to a fixing support for bridge detection equipment, and the fixing support comprises an annular support body which is disposed on bridge piers in a sleeving manner, is provided with an interval between the outer peripheral surfaces of the bridge piers on the inner peripheral surface, and is provided with a guide rail in the circumferential direction; a hoisting assembly whichcomprises a winch arranged on the bridge floor corresponding to the bridge pier and a pulley assembly fixed to the bridge floor, wherein a hoisting rope on the winch penetrates through the pulley assembly to be connected with the annular support body; an air bag assembly which is arranged on the inner side wall of the annular support body, wherein the air bag assembly is communicated with an airpump through an inflation pipe; and an angle adjusting device of which one end is slidably connected into the guide rail, and the other end is connected with the bridge detection equipment. A supporting platform can be provided for the detection device so that the detection and maintenance work of underwater and high-altitude parts of the bridge pier stud can be completed smoothly; in addition, the electric tackle can be started to slide in the guide rail, and then the detection equipment is driven to conduct 360-degree detection in the circumferential direction of the pier.

Description

technical field [0001] The invention relates to the technical field of auxiliary tools for bridge detection, in particular to a fixed bracket for bridge detection equipment. Background technique [0002] With the advancement of my country's marine strategy, the demand for underwater engineering testing has increased dramatically. As of the end of 2016, the total number of road bridges in my country is close to 800,000, and the total number of railway bridges has exceeded 200,000. It has become the world's largest bridge country without a doubt. The number of bridges in service in my country's road network that is entering the maintenance period is increasing day by day. There are more than 100,000 bridges that are dangerous, and the market demand for inspection and repair is huge. [0003] At present, the inspection of bridges is mainly through visual appearance inspection and sampling inspection. According to different principles, the commonly used detection methods for vi...

AI Technical Summary

Problems solved by technology

Detection devices such as sonar and underwater cameras have the advantages of high accuracy and flexibility. The disadvantage is that they have high requirements for the detection environment and can only provide detection pictures from local angles.

At present, the application of underwater detection equipment is greatly affected by the environment such as undercurrents, etc.

At the same time, when detecting underwater structures, it is necessary to adjust the angle of the sonar equipment in order to better observe the situation of the bridge pier, but there is no effective angle adjustment bracket suitable for the underwater work of sonar equipment
