An adsorption climbing bridge crack detection robot

Abstract

The invention discloses an adsorption climbing bridge crack detection robot, which comprises a knee joint module, a camera module and two ankle joint modules, wherein the knee joint module includes a steering gear A and two connecting pieces; each ankle joint module is fixedly installed respectively On a connector of the knee joint module, and each ankle joint module includes an ankle joint bracket and a drive unit and a suction cup module installed on the ankle joint bracket; the suction cup module includes a suction cup, a suction cup rotating shaft and a vacuum pump unit, and the vacuum pump unit It is fixedly installed on the first support; there are more than one camera module, and the camera module is rotatably installed on the ankle support, which is used to photograph defects on the bottom surface of the bridge. The two ankle joint modules of the present invention can not only be turned over normally, but also can be rotated in a plane parallel to the bottom surface of the bridge, which can realize the functions of walking, overcoming obstacles and turning, and is convenient for detection.

Description

technical field [0001] The invention belongs to the field of robots, and more specifically relates to an adsorption-climbing bridge crack detection robot. Background technique [0002] With the rapid development of my country's economic construction, the total number of bridges in my country has ranked among the top in the world. As of the end of 2012, the total number of highway bridges in my country reached 621,900, with a total length of 27,260,600 meters. However, due to structural design defects, low construction quality, poor inspection and maintenance, and overloaded operation, bridge accidents occur from time to time, and there are currently many dangerous bridges in our country, which seriously threaten the safety of people's lives and property. Therefore, it is particularly important to strengthen bridge inspection and timely repair. [0003] Among all kinds of bridge defects, bridge cracks are the dominant factor, which is the concentrated expression of the dang...

Problems solved by technology

[0004] However, the current detection methods for bridge bottom cracks at home and abroad basically use large-scale mechanical equipment such as lift-type inspection vehicles, hanging basket-type inspection vehicles and truss-type inspection vehicles to carry maintenance personnel to observe with the naked eye or manually carry small equipment to observe and record. High testing costs, cumbersome equipment, low efficiency, difficulty in ensuring personnel safety, and the quality of testing is too dependent on the quality of personnel, which cannot guarantee accuracy and stability.
