Integral stress state real-time monitoring system for tower mast structure

Abstract

The invention relates to an integral stress state real-time monitoring system for a tower mast structure, which comprises a stress monitoring and state analysis module, a wireless lifting hook monitoring module and an analysis processing module, and the analysis processing module is connected with a sound-light alarm module; the system has the advantages that the stress monitoring and state analysis module is mounted between the two standard knots of the tower mast structure, and the wireless lifting hook monitoring module is mounted between the lifting hook and the steel wire rope, so that the working state of the tower mast structure and the load borne by the lifting hook can be monitored in real time; the analysis processing module performs real-time analysis and comparison on the real-time monitoring data and a safety early warning threshold value, when the real-time monitoring data exceeds the safety early warning threshold value, the analysis processing module triggers the sound-light alarm module to give an alarm instruction, and the sound-light alarm module gives out sound and flash alarm signals; and therefore, real-time safety analysis and early warning of the working state of the tower mast structure are achieved, the whole monitoring system does not need manual intervention, and safety monitoring personnel are saved.

Description

technical field [0001] The invention relates to an integral force state real-time monitoring system for a mast structure. Background technique [0002] In engineering construction, a large number of towering mast structures are used to bear large loads. In order to reduce weight and improve bearing capacity, this kind of structure generally adopts the form of space lattice frame structure, such as the tower crane (tower crane) The tower body, the load-bearing frame of the construction elevator (construction elevator), the frame body of the lifting gantry, and the holding pole for the assembly of the iron tower of the overhead transmission line. [0003] The above-mentioned tower-mast structures are designed to limit the maximum limit load that can be borne, which is called the rated load. Some tower mast structures have different rated loads under different working conditions. Taking the tower crane as an example, when the hoisted load (heavy object) is at different positi...

AI Technical Summary

Problems solved by technology

For example, tower cranes can be equipped with weight limiters, lifting moment limiters, etc., but the devices are more complicated; the poles used for the assembly of overhead transmission line towers are currently trying to install tension sensors on the stay wires and support ropes, but if the installation of parallel The tension sensor has low measurement accuracy. If a series tension sensor is installed, the height of the pole will gradually increase with the assembly of the tower, which will seriously affect the construction operation, inconvenient assembly and disassembly, and poor practicability
