Bridge safety detection device

Abstract

The invention relates to the technical field of bridge detection, and particularly relates to a bridge safety detection device which comprises two clamping and positioning mechanisms and a movable detection mechanism. The clamping and positioning mechanisms are installed on guardrails on the two sides of a bridge, and the lower ends of the clamping and positioning mechanisms are connected with the movable detection mechanism; and each clamping and positioning mechanism comprises a connecting frame, a positioning frame, a clamping and moving branch chain, a balance weight frame, a first sprayer and a V-shaped frame. According to the invention, crack detection can be carried out on the two sides of a bridge at the same time, the detection efficiency is improved, meanwhile, the stability of the detector is guaranteed in the detection process, the situation that the detection effect of the detector is affected due to shaking is avoided, and bridge cracks and bridge guardrails can be sprayed and marked in the detection process; and workers can rapidly detect the bridge crack position.

Description

technical field [0001] The invention relates to the technical field of bridge detection, in particular to a bridge safety detection device. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to cross mountains, poor geology, or to meet other traffic needs. Buildings that make traffic more convenient thing. As the bridge is put into service, the surface of the bridge will gradually age and crack. Therefore, it is necessary to carry out regular safety inspections on the bridge. [0003] At present, the existing bridge safety detection devices have the following problems in the process of detecting bridges: a. Most of the existing bridge detection devices use the telescopic structure to drive the detector to move and detect on the lower end of the bridge. During t...

Problems solved by technology

[0003] At present, the existing bridge safety detection devices have the following problems in the process of detecting bridges: a. Most of the existing bridge detection devices use the telescopic structure to drive the detector to move on the lower end of the bridge for detection. The instrument cannot accurately detect the cracks of the bridge. At the same time, most of these telescopic structures are single-cantilever stressed structures, which makes the service life of this type of device short; b. Most of the existing bridge detection devices can only detect cracks on one side of the bridge. It makes the bridge detection need to be carried out twice, which increases the detection time; c. Many existing detection devices do not have a marking function, and cannot mark the position of the crack detected by the detector, which is not convenient for subsequent staff to quickly find bridge cracks position, increase work intensity
