Steel structure bolt loosening detection robot

Abstract

The invention discloses a steel structure bolt loosening detection robot. The steel structure bolt loosening detection robot includes a detection tail end, a multi-degree of freedom robotic arm and awalking device, wherein the detection tail end is mounted on the walking device through the multi-degree of freedom robotic arm, the walking device provides a walking function for position adjustmentof the detection tail end, the detection tail end includes a substrate, a spring, a magnetic meter holder adsorption device and two piezoelectric ceramic sheet sensors, the spring and the magnetic meter holder adsorption device are fixedly juxtaposed to the bottom of the substrate, one of the piezoelectric ceramic sheet sensors is mounted on the bottom of the spring, the other piezoelectric ceramic sheet sensor is mounted on the bottom of the magnetic meter holder adsorption device, the two piezoelectric ceramic sheet sensors are respectively taken as a driver and a receiver, impedance analysis is utilized to perform bolt loosening detection, the walking device is a crawler walking device, and a permanent magnet strip is arranged on a crawler. The steel structure bolt loosening detection robot is advantaged in that the detection tail end can be driven by the multi-degree of freedom robotic arm to achieve rapid positioning, remote control on the robot can be further achieved for detection, the risk of manual detection is reduced, and detection efficiency is improved.

Description

technical field [0001] The invention belongs to the field of industrial robots, and relates to a bolt looseness detection robot, in particular to a steel structure bolt looseness detection robot. Background technique [0002] my country's steel structure buildings are mainly bridges with huge volume, and bolt connection is the most important connection method. For bridges, the importance of maintenance is self-evident. At present, known bolt loosening detection methods include ultrasonic methods, modal analysis methods, image recognition methods, etc. Ultrasonic and modal analysis methods require manual field operations and large-scale equipment support, while image recognition methods can be used under strong light conditions outdoors. Ineffective. In the existing technology, the use of piezoelectric ceramic sensors for bolt loosening detection has fast response and accurate detection, such as: Zhang Jing, Xu Xia, Zhang Zhiwen's structural damage detection technology base...
