Bridge detecting robot based on negative-pressure absorption

Abstract

The invention discloses a bridge detecting robot based on negative-pressure absorption. The bridge detecting robot consists of an absorption control module, a motion control module, a disease detection module and a light outer shell, wherein the absorption control module comprises a sealing cavity, a negative-pressure generation device, an air-pressure sensor, a single-chip-microcomputer main control board, a wireless instruction transmission module, a wireless instruction transmission module and a remote control device; the motion control module comprises four moving wheels, four steering engine drivers, a single-chip-microcomputer main control board, a wireless instruction transmission module, a wireless instruction transmission module and a remote control device; the disease detection module comprises a camera unit and a ground image processing unit; and the light outer shell is fixed by wire binding belts which penetrate through the installing holes on the front edge and the rear edge of a supporting bottom plate, and the negative-pressure generation device, the air-pressure sensor, the single-chip-microcomputer main control board, the wireless instruction transmission modules, the wireless instruction transmission module and the four steering engine drivers are put into the outer shell. The bridge detecting robot disclosed by the invention has the advantages that the anti-wind capability is strong, the working efficiency is improved, the detection period is shortened and the safety risk is also greatly reduced.

Description

technical field [0001] The invention belongs to the field of bridge disease detection, in particular to a bridge detection robot based on negative pressure adsorption. Background technique [0002] Bridge engineering is related to all aspects of national life and has a significant role in promoting the country's economy. Now there are various large bridges in use or under construction, the importance of bridge safety has been paid more and more attention, and the demand for effective means of bridge detection has become increasingly strong. Cracks or other diseases caused by structural changes often appear on the back of the bridge. These diseases need to be carefully inspected. The most intuitive visual inspection is indeed the most effective method. At present, the traditional method of this type of inspection is to build scaffolding from the ground under the bridge or send the staff to the inspection area through a bridge inspection vehicle. However, these methods have ...

Problems solved by technology

However, these methods have obvious shortcomings, not only time-consuming and labor-intensive, high cost, poor maneuverability, greatly affected by light and weather environment, but also have certain hidden dangers to the personal safety of bridge inspectors.

Moreover, the slow driving speed of the bridge inspection vehicle or the limitation of the observation distance will affect the detection results, especially once the long-term observation causes the fatigue of the inspection personnel, it is impossible to guarantee the normal inspection work

[0003] The Chinese patent application number 201010223164.2 discloses a bridge detection robot based on a quadcopter. The quadcopter is used as a carrier to detect bridges. Performance and reliability will be greatly affected, so the applicability is limited
