Safety monitoring and management system for gantry crane

Abstract

A safety monitoring and management system for a gantry crane comprises weight sensors for detecting the weight signals of gantry crane grabbing beams, displacement sensors for detecting inspection penetrating bolts of the gantry crane grabbing beams, a height sensor for detecting the heights of the gantry crane grabbing beams, an air velocity sensor for detecting the air velocity of the environment in real time, an anti-collision sensor for detecting the driving safety distance of large vehicles and a face sensor for detecting work licenses of drivers. The weight sensors, the displacement sensors, the height sensor, the air velocity sensor, the anti-collision sensor and the face sensor are connected with a safety management system main machine. The safety management system main machine is connected with an alarm, a controller and an industrial control machine. A stress strain monitoring sensor is connected with a stress strain collection instrument. The stress strain collection instrument is connected with the industrial control machine. By the adoption of the safety monitoring and management system, a complete analytical judgment can be made for the fault generation process of equipment, and a scientific basis is provided for equipment improvement and management.

Description

technical field [0001] The invention relates to the field of dam gate monitoring, in particular to a gate machine safety monitoring management system. Background technique [0002] Most of the barrage dams of China's hydropower stations are equipped with gantry cranes at the top of the dam. Its main function is to open or close the upstream and downstream gates of the dam. ), lift or lower the gate, open the gate when lifting, and close the gate when descending. When there is a heavy rain in the upper reaches of the river, the door operator must be able to open the floodgate in time according to the order of water regulation when flood discharge is required; when it is necessary to store water, the door operator must be able to quickly close the gate according to the order of water regulation; otherwise, when it is necessary to open the gate If the door machine fails and the gate cannot be opened, the flood may overflow the dam, which may cause immeasurable losses to the li...

AI Technical Summary

Problems solved by technology

In severe cases, it may even cause incalculable losses. Therefore, the safety management system of the dam crest gantry crane urgently needs the real-time online monitoring and alarm function of the mechanical stress of the gantry crane girder
