A device for detecting cracks on the bottom surface of a bridge

Abstract

The application relates to a device for detecting cracks on the bottom surface of a bridge, which includes a car body. There are two car bodies, and the two car bodies are respectively arranged on both sides of the bridge width direction. It is fixed on the vehicle body, and the other end extends toward the bottom of the bridge. A mounting platform is fixed on the side of the connecting frame far away from the vehicle body. Guide rails are arranged between the mounting platforms on the vehicle bodies on both sides, and the guide rails are arranged under the bridge. An inspection vehicle is arranged on the guide rail, the inspection vehicle slides along the length direction of the guide rail, and an image transmission device is arranged on the inspection vehicle towards the bottom surface of the bridge. This application has the advantages of installing guide rails on two installation platforms, coordinating with the inspection vehicle with image transmission equipment to slide along the guide rails, recording the situation at the bottom of the bridge and feeding it back to the computer, and the technicians use the computer on the bridge surface Observing the bottom of the bridge does not require technicians to work at heights, reducing the probability of safety accidents.

Description

technical field [0001] The present application relates to the field of bridge detection equipment, in particular to a crack detection device on the bottom surface of a bridge. Background technique [0002] With the increase of traffic volume in today's society, the development of bridge construction in our country is also increasing day by day, and many newly built bridges often have some natural diseases and bridge structure defects that cause traffic accidents. Therefore, in order to ensure the safe operation of the bridge, it is necessary to inspect the bridge. By inspecting the current technical status of the bridge and the nature, location, severity and development trend of the damage, the main reasons for the defects and damage can be clarified, so that the existence of the bridge can be identified. More accurate analysis and evaluation of defects and damages. [0003] Existing bridge bottom inspection is mainly for technicians to take the hanging basket of bridge ins...

Problems solved by technology

[0003] Existing bridge bottom inspection is mainly for technicians to take the hanging basket of bridge inspection vehicle, and adjust the boom to enter the bridge bottom for inspection. This inspection method requires technicians to work at high altitude. During the inspection process of bridges with long lengths, vehicles It needs to be moved, and the hanging platform will shake when the vehicle is moving, which will easily cause the technician to fall, thus causing a safety accident
