Hoisting machine safety monitoring system and deflection measuring method of bridging machine girder

Abstract

The invention relates to a hoisting machine safety monitoring system. The hoisting machine safety monitoring system comprises a monitoring host. The monitoring host comprises a monitor. The monitor is in communication connection with a first remote extension set, a second remote extension set, a third remote extension set and a fourth remote extension set through a wireless module. The first remote extension set comprises a tilt angle sensor, an overload limiter, an anemograph and a PLC. The second remote extension set comprises an electronic compass. The third remote extension set comprises a liquidometer. The fourth remote extension set comprises a tilt angle sensor. The monitoring host is in communication connection with a cloud server and an intelligent mobile terminal through a communication module. The cloud server is in communication connection with a video tape recorder and a vidicon through a communication module. The hoisting machine work process can be monitored, and important running parameters and safety states can be recorded and managed. Production situation close linkage and real-time equipment body data display can be achieved, the intrinsic safety performance of large hoisting machines is improved, major hoisting machine accidents are prevented and reduced, and personal life safety is effectively guaranteed.

Description

technical field [0001] The invention relates to the field of an automatic network online monitoring system for special hoisting equipment, in particular to a hoisting machinery safety monitoring system and a method for measuring the deflection of a main girder of a bridge erecting machine. Background technique [0002] The bridge erecting machine is a special high-altitude mobile lifting machine; the working environment is harsh, and the site management and maintenance are difficult. With the development of society, modern equipment is developing toward large-scale integration, intelligent automation, and high-speed complexity. The safety monitoring facilities and safety management of engineering equipment are particularly important. According to the standard requirements of the "Overweight Machinery Safety Monitoring and Management System" introduced by our country, it clearly points out the requirements for the safety monitoring and management of large-scale hoisting machi...

AI Technical Summary

Problems solved by technology

[0003] At present, all the large-scale hoisting machinery safety monitoring systems in use, only a single installation of the monitoring system can no longer meet the requirements of on-site use, mainly in the following aspects:

[0004] 1. It only has the local management function, and the status detection of the device itself only reminds the on-site personnel;

[0005] 2. It only monitors the status of the device itself, without the daily management function of the device;

[0006] 3. Unable to grasp the status of the equipment in real time;

[0007] 4. It is difficult to upgrade stand-alone products
