Problems solved by technology
This detection method not only takes up a lot of labor and has potential safety hazards, but also mainly relies on human eye recognition, which affects the accuracy of detection
Highway bridge inspection vehicles based on ultrasonic, shock rebound wave, acoustic emission and other detection methods have been developed in recent years, but the difference between railway box girders and highway girders is relatively large, and it cannot be applied to the detection of railway box girders.

Embodiment Construction
[0032] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0033] like Figure 1 to Figure 7 As shown, a box girder inspection robot includes an AGV trolley 10, a top inspection mechanism 20, a lifting mechanism 30, a side inspection mechanism 40 and a retracting mechanism 50, wherein:
[0034] The AGV trolley 10 is set lower and used to drive other mechanisms to move among the box girders;
[0035] The top inspection mechanism 20 is arranged above the AGV trolley 10 and is used to detect cracks in a wide range on the top surface of the box girder;
[0036] The lifting mechanism 30 is arranged between the top inspection mechanism 20 and the AGV trolley 10 and is used to adjust the longitudinal position of the top inspection mechanism 20;
[0037] The side inspection mechanism 40 is provided with a pair an...

The invention discloses a box girder detection robot, and relates to the technical field of box girder detection, the box girder detection robot comprises an AGV trolley, a top detection mechanism, a lifting mechanism, a side detection mechanism and a folding and unfolding mechanism, the AGV trolley is arranged close to the lower part and is used for driving other mechanisms to move in a box girder; the top detection mechanism is arranged above the AGV trolley and is used for carrying out large-range crack detection on the top surface part of the box girder; the lifting mechanism is arranged between the top detection mechanism and the AGV trolley and is used for adjusting the longitudinal position of the top detection mechanism; the side detection mechanisms are symmetrically arranged on the left side and the right side of the AGV trolley, and the side detection mechanisms are used for carrying out large-range crack detection on the side face part of the box girder; the folding and unfolding mechanisms are correspondingly arranged between the side detection mechanisms on the two sides and the AGV trolley, and the folding and unfolding mechanisms are used for adjusting the transverse positions of the side detection mechanisms. In conclusion, the box girder detection robot has the advantages of being reasonable in scheme design, convenient in structure adjustment and comprehensive and efficient in detection.
Description
technical field [0001] The invention relates to the technical field of box girder detection, in particular to a box girder detection robot. Background technique [0002] At present, for the crack detection of railway concrete bridges, the method of manual periodic detection is widely used at home and abroad. This detection method not only takes up a large labor force and has potential safety hazards, but also mainly relies on human eye recognition, which affects the detection accuracy. Highway bridge inspection vehicles based on ultrasonic, shock rebound wave, acoustic emission and other detection methods have been developed in recent years, but the difference between railway box girders and highway girders is relatively large, and it cannot be applied to the detection of railway box girders. Contents of the invention [0003] The object of the present invention is to provide a box girder inspection robot to solve the above-mentioned defects caused in the prior art. [0...
