A safety monitoring system and method for a double-rocker arm support structure

By installing strain gauge and tension sensors on the double rocker arm support, the torque difference of the rocker arms and the strain of the support are monitored in real time. This solves the problem that existing technologies cannot effectively monitor unbalanced torques, and achieves efficient and reliable monitoring of the safety of the load-bearing structure, ensuring construction safety.

AI Technical Summary

Technical Problem

Existing double-rocker gantry cranes are difficult to monitor unbalanced moments during construction, resulting in high operational risks. Current technology cannot ensure the safety of the load-bearing structure.

Method used

Strain gauge and tension sensors are used to monitor the torque difference between the two rocker arms on both sides of the double rocker arm support and the strain of the slewing support in real time. By calculating the unbalanced torque difference, it is ensured that it is within the allowable range. An angle sensor is installed to monitor the pitch angle of the rocker arm, and a tension sensor is used to monitor the lifting force to achieve safety monitoring.

Benefits of technology

It enables real-time, convenient, and reliable safety monitoring of the load-bearing structure of the double rocker arm scaffold, has a wide range of applications, high work efficiency, and ensures construction safety.

Abstract

A system and method for monitoring the safety of a double-rocker arm gantry structure are disclosed. The monitoring method includes: Step 1: Measuring the lengths of the rocker arms on both sides of the double-rocker arm gantry, generating a standard unbalanced moment using a standard slewing support specimen, and calibrating the bending stiffness of the slewing support; Step 2: Installing a first angle sensor and a second angle sensor on the rocker arms on both sides of the gantry, installing a first strain gauge sensor and a second strain gauge sensor at symmetrical positions on both sides of the slewing support, and installing tension sensors on the lifting hooks of the left and right rocker arms respectively. This invention utilizes strain gauge sensors and tension sensors to calculate the torque difference between the two rocker arms and record the strain of the slewing support rod, thereby reducing the size of the monitoring equipment and enabling real-time and convenient monitoring of the safety of the gantry structure.
