Level difference detection system of bridge erecting machine

Abstract

A level difference detection system for a bridge erecting machine, characterized in that: a container is respectively arranged at the front and rear ends of the main girder of the bridge erecting machine, the two containers are connected through a pipeline at the bottom, and a liquid level is respectively installed at the same position in the two containers The sensor, the liquid level sensor is connected with the signal processing module. The liquid level sensor is installed at the bottom of the container. The different data detected by the liquid level sensor between the two containers is transmitted to the signal processing module, so that the signal processing module performs subtraction and calculates the absolute value, which can improve the accuracy of the level difference and speed up the calculation time of the level difference. The analog signal or digital signal is transmitted externally through the signal processing module, so that information can be fed back faster. The level difference detection accuracy of the invention can reach ±1mm, has the advantages of convenient installation and fast operation speed, and is a new generation level difference detection system for bridge erecting machines.

Description

Technical field [0001] The invention relates to a horizontal height difference detection system of a bridge erecting machine, belonging to the technical field of bridge erecting machine safety. Background technique [0002] The bridge erecting machine is the equipment that puts the prefabricated beams on the prefabricated bridge piers. The bridge erecting machine belongs to the category of cranes, because its main function is to lift the beams, and then transport them to the location and put them down. Due to the long body length, self-heavy weight, and multiple operating procedures, the conditions required for it during operation are very harsh. The level difference between the front and rear of the bridge erecting machine exceeds the limit value is an important reason for the major accidents of the bridge erection machine. The current bridge erection The accuracy of the detection data of the height difference of the machine level is not enough, and the calculation of the opera...

AI Technical Summary

Problems solved by technology

Due to the long body, heavy weight, and many operating procedures, the conditions required for the operation are very strict. The level difference between the front and rear of the bridge erecting machine exceeds the limit value, which is an important reason for major accidents in the bridge erecting machine. The current bridge erecting machine The accuracy of the level difference detection data of the bridge erecting machine is not enough, and the operation calculation is not timely, and the feedback information is slow, which all reflect the serious shortcomings of the level difference detection system of the bridge erecting machine
