Bolt anti-loosening monitoring device for fan tower drum

Abstract

The invention relates to the technical field of fan tower drums, and discloses a fan tower drum bolt anti-loosening monitoring device which comprises an L-shaped plate, an ultrasonic probe and a bolt body installed on a fan tower drum, the L-shaped plate is fixedly connected to the position, located below the bolt body, of one side of the fan tower drum, and a fixing frame is fixedly connected to the top of the L-shaped plate; a protective shell attached to the bolt body is fixedly connected into the fixing frame, a fixing ring is slidably connected into the protective shell, and the ultrasonic probe is fixedly connected into the fixing ring and attached to the bolt body. According to the device, the bolt can be prevented from continuing to loosen in the maintenance process, the potential safety hazard of the fan tower drum is reduced, the ultrasonic probe can more accurately monitor the bolt, the monitoring accuracy of the monitoring device is improved, the ultrasonic probe can be more tightly contacted with the bolt, and the service life of the ultrasonic probe is prolonged. And the monitoring accuracy of the monitoring device is further improved.
