Negative pressure absorption climbing type robot used for detecting fissure of bridge

Abstract

The invention discloses a negative pressure absorption climbing type robot used for detecting a fissure of a bridge. The negative pressure absorption climbing type robot used for detecting the fissure of the bridge comprises a camera shooting unit, a front mechanical foot, a rear mechanical foot and a wireless communication unit. According to the negative pressure absorption climbing type robot used for detecting the fissure of the bridge, the front mechanical foot is connected with the rear mechanical foot through a joint coupling mechanism, the front mechanical foot and the rear mechanical foot are respectively provided with a negative pressure absorption assembly and a walking driving assembly, and therefore the front mechanical foot and the rear mechanical foot can be sucked on the surfaces of bridges under different work conditions to achieve climbing and walking; the camera shooting unit is arranged on the front mechanical foot and is used for shooting an area to be detected and sending the shot results to the wireless communication unit; the wireless communication unit is arranged on the rear mechanical foot and is used for receiving the results shot by the camera shooting unit and transmitting the results to a control terminal and receiving a control command from the control terminal. The negative pressure absorption climbing type robot used for detecting the fissure of the bridge has the advantages that the detection of the fissure of the bridge can be achieved conveniently, fast and accurately, the detection of the fissure of the bridge can be controlled conveniently, subjective interference factors of people can be effectively eliminated, and detection cost is reduced. The negative pressure absorption climbing type robot used for detecting the fissure of the bridge is particularly suitable for detection of the bottom surfaces of various complicated bridges.

Description

technical field [0001] The invention belongs to the technical field of bridge detection, and more specifically relates to a negative pressure adsorption climbing robot for detecting bridge cracks. Background technique [0002] Cracks on the surface of concrete bridges are mutations in the process of internal damage accumulation, and they are the concentrated expression of the dangerous degree of internal damage. Therefore, their information content is very large, and they are of key significance for predicting and warning bridge dangers. The structural cracks of most bridges mainly occur at the bottom of the bridge, which is difficult to detect. At the same time, the structure of bridges is becoming larger and more novel, which makes the detection of cracks more difficult to solve. Therefore, if cracks in concrete bridges can be detected in an early stage, and their development can be tracked, and maintenance and repair can be carried out in a timely manner, the maintenance ...

AI Technical Summary

Problems solved by technology

[0004] Studies have shown that the existing bridge crack detection methods mainly have the following defects or deficiencies: (1) Since the detection process requires the use of detection platforms, such as scaffolding or bridge inspection vehicles, many bridges are hundreds of meters long, or even thousands of meters long, It takes a lot of manpower and material resources to complete the inspection work; (2) There are often human subjective interference factors in the inspection process, and different inspection personnel have different judgment results, and long-term naked eye observation is likely to cause visual fatigue and affect Human observation and judgment, which in turn affect work efficiency; (3) There are potential safety hazards: manual detection requires staff to stand on a mobile platform for detection, and there is a huge potential safety hazard for complex working conditions
