Bolt or nut loosening monitoring device

Abstract

The invention discloses a bolt or nut loosening monitoring device, which comprises a collection module for collecting a loosening signal of a bolt or a nut, a main control module which is connected with the collection module and is used for processing the signal collected by the collection module and judging whether the bolt or the nut is loosened or not according to the collected signal, and a target module which is used for issuing an alarm according to the judgment result of the main control module, and the bolt or nut loosening monitoring device is characterized by also comprising a sensing module which is arranged on a monitored part of the bolt or the nut, wherein the sensing module comprises a deformation sensor (1), the deformation sensor (1) is contacted with the bolt or the nut through an ejector pin (2), and the deformation sensor (1) is connected with the collection module through a signal wire; and when the bolt or the nut is loosened, the bolt or the nut makes the ejector pin (2) move towards the deformation sensor (1), and the loosening deformation quantity of the bolt or the nut is transmitted by the deformation sensor (1) to the collection module through the signal wire. Through the structure by acquiring the deformation signal of the sensor through the ejector pin and the sensor or through the recognition means of the collection module, the purpose for monitoring the loosening of the bolt or the nut is realized.

Description

technical field [0001] The invention belongs to the technical field of hidden danger monitoring, and in particular relates to a bolt or nut loosening monitoring device. Background technique [0002] All kinds of bolts and their nuts are indispensable and play an extremely important role in industries such as industrial machinery and equipment, transportation, mining, energy and power equipment. However, the loosening of bolts or nuts due to vibration caused by mechanical movement, metal stress, external load and other factors has always been a headache. Once the bolts or nuts loosen, the bolts will break. [0003] For many years, people have tried to make the bolts not loosen after they are fixed by different methods, but in fact, people have not been able to find a solution that can be applicable to various bolts or nuts and can completely prevent the bolts or nuts from loosening. Usually, the method of judging whether the bolts or nuts are loose is: 1. Regular patrol insp...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a bolt or nut looseness monitoring device, which solves the problems in the prior art that whether the bolts or nuts are loose requires manual regular patrol inspection or on-site visual inspection, resulting in the inability to effectively avoid the occurrence of accidents, etc.
