Bolt looseness detection device and system

Abstract

The invention discloses a bolt looseness detection device and system, and the device comprises a bolt end part and two wire end parts, and the two wire end parts are respectively in separable magneticand electrical connection with another two composite connectors disposed on the bolt end part through a composite connector. The bolt end part is combined on a bolt to be detected, when the bolt to be detected is loosened, the bolt end part is driven to twist, and when the bolt end part twists beyond a certain angle, the composite connector between the bolt end part and the wire end part releasesthe magnetic and electrical connection relationship, and the electrical connection state between the bolt end part and the wire end part is detected, therefore, the looseness of the bolt to be detected can be detected. Furthermore, a plurality of bolt end parts are respectively combined on a bolt to be detected, and the bolt end parts are respectively in magnetic and electrical connection throughline end parts, so that a bolt looseness detection system is formed.

Description

technical field [0001] The present invention relates to a bolt looseness detection device and system, in particular to a device and system that establishes a magnetic and electrical multiple connection relationship with the bolt to be tested, and detects whether the bolt is loose by judging the electrical connection state. Background technique [0002] For equipment such as fans, loose bolts or screws often occur due to engine vibration or environmental influences. If the bolts or screws loosen in some important parts, it will cause great safety hazards. [0003] In order to effectively know whether the bolts or screws in important parts are loose, it is necessary to carry out inspection in a planned way. The easiest way is to use manual inspection, but there are many uncertain factors in manual inspection. For example, the working environment of many equipment is harsh, and manual operation is not easy. , Another example is the large number of bolts or screws in the whole s...

[0003] In order to effectively know whether the bolts or screws in important parts are loose, it is necessary to carry out inspection in a planned way. The easiest way is to use manual inspection, but there are many uncertain factors in manual inspection. For example, the working environment of many equipment is harsh, and manual operation is not easy. , and if the number of bolts or screws in the whole set of equipment is huge, manual inspection is time-consuming and labor-intensive, which will also affect the normal operation of the equipment
