AI Technical Summary

Technical Problem

Existing technologies lack methods for automatic detection and timely feedback of loose bolts, which increases the probability of bolts falling off and may lead to construction accidents.

Method used

Design a bolt anti-loosening alarm system, including bolt preload, bolt fasteners and detection module. The system detects bolt displacement through sensors and communicates with the data center to provide real-time feedback on loosening status. Based on the placement of bolts in critical areas of the equipment, the system generates the best operation and maintenance plan.

Benefits of technology

It enables timely detection and feedback of loose bolts, reduces the risk of bolt detachment, reduces costs, and provides targeted operation and maintenance solutions.

Abstract

The present application belongs to the technical field of bolt falling early warning, in particular to a bolt anti-falling alarm system, specifically, a bolt pre-tightening part and a bolt fastener are added during bolt installation to enhance the fastening of the bolt, and a detection module is arranged on the bolt fastener, the detection module connects the bolt fastener and the bolt pre-tightening part through the lower threaded rod, so that the detection module can better detect the loosening of the bolt and timely transmit the sensing signal to the data center, after the data center receives the sensing signal, corresponding early warning and reminding are carried out, in addition, the bolts can also be laid according to the important areas of the equipment to achieve the effects of reducing cost and timely feedback, and the best operation and maintenance scheme for bolt loosening can also be generated. The present application can solve the problem that there is currently a lack of a means to automatically detect and timely feedback the bolt loosening condition.
