Bolt looseness detection device based on visual monitoring

Abstract

The invention discloses a bolt looseness detection device based on visual monitoring. The bolt looseness detection device comprises an equipment shell, a power supply for providing power for equipment, a moving unit and an obstacle avoidance unit, the moving unit moves the equipment, and the obstacle avoidance device performs active avoidance movement when the equipment moves and encounters an obstacle; and the data acquisition module is mounted on the equipment shell and is used for identifying the anti-loosening wire on the head of the bolt or the nut. According to the technical scheme of the invention, 1, the influence of space limitation on detection is avoided; 2, the labor and time are saved, and convenience and rapidness are achieved; 3, the device is portable and mobile and adapts to various working conditions. 4, intelligent detection is achieved, rapidness and high efficiency are achieved, and errors caused by manual detection are avoided. and 5, automatic data storage, classified management, later maintenance construction and historical data query are relatively convenient.

Description

technical field [0001] The invention relates to the technical field of bolt fastener connection, and in particular, to a device for detecting loose bolts based on visual monitoring. Background technique [0002] Similar products for large-scale bolt / nut loosening monitoring can only be detected manually. The detection methods include: 1. Visually check whether the anti-loosening wire is misaligned; 2. Knock the bolt to make a sound, and judge whether the bolt is loose according to experience; Judging whether it is loose or not by tightening torque. The disadvantages are: labor and time-consuming, and the space is narrow and the location cannot be tested. In the prior art: 1. The cost of bolt monitoring is high: using contact-type bolt axial force monitoring technologies such as ultrasound, force ring, strain gauge, grating, and manual torque, it is necessary to add sensor parts to the monitored bolts, so that multiple The monitoring cost of bolts has increased significantl...

Disadvantages are: labor and time-consuming, and the space is narrow and the location cannot be detected

In the prior art: 1. The cost of bolt monitoring is high: using contact-type bolt axial force monitoring technologies such as ultrasound, force ring, strain gauge, grating, and manual torque, it is necessary to add sensor parts to the monitored bolts, so that multiple The monitoring cost of bolts has increased significantly; 2. The engineering implementation is complicated: for each bolt using the contact bolt axial force monitoring technology, wires or wireless methods are required, resulting in complex on-site construction and a substantial increase in engineering costs; 3. Need to change the bolt connection structure: Some contact bolt monitoring technologies, such as strain gauges, gratings, and force rings, will change or damage the bolt connection structure, making the necessity of bolt monitoring greatly reduced
