A video detection device for low headroom bridges

Abstract

The invention provides a video detection device for a low clearance bridge. The problems that image data are difficult to collect, the data are not accurate, and the operation is inconvenient are solved when existing equipment is used for detecting the quality of the bottom of the low clearance bridge. The video detection device for the low clearance bridge comprises a controller and a video detection device body; the video detection device body comprises a base; a shell is fixed on the base; and a camera is fixed above the shell. According to the video detection device for the low clearance bridge, as a turntable slides or rotates up and down through rotation conversion between a locking cam in a chuck and the turntable or the shell and a set of multiple motions is realized by using one set of mechanism, the number of mechanisms in the equipment is greatly reduced and the operation is made simpler and more convenient; and as the whole mechanism is fixed through the friction between the locking cam and the turntable or the shell, the later maintenance cost is low; and when the equipment locking is invalid, only replacement of the locking cam is needed so that the maintenance cost is saved and the maintenance efficiency is enhanced.

Description

technical field [0001] The invention relates to the technical field of bridge detection devices, in particular to a video detection device for bridges with low headroom. Background technique [0002] Bridge inspection is an important content in bridge management and maintenance, and it is an important basis for judging the technical status of bridges. In urban and highway projects, there is often low clearance at the bottom of the beam at both ends of the bridge. Since the inspectors cannot enter the inspection, it becomes a blind spot for inspection. In the evaluation of the technical status of the bridge, some data are missing, and there is a large gap. Security risks. [0003] In the utility model patent with application number 201621385762.9, a video detection device for low headroom bridges is disclosed. The device includes a remote control, a remote control car, a bracket, a camera, and an LED lighting lamp. The remote control is the remote control terminal of the rem...
