Problems solved by technology

The slag scraper is usually installed in a harsh environment full of high temperature and metal dust; the slag scraper moves frequently and vibrates greatly when it is working, which is very detrimental to the detection accuracy, stability and reliability of the sensor
In addition, once the sensor installed in the cylinder fails, it is very difficult to repair

Abstract

A detection and calculation method for four-dimensional motion position parameters of a crawler loader. The method comprises the following steps: 1, setting a marker serving as a reference object on the crawler loader, setting cameras above and on the side of the crawler loader, and shooting a current motion position image of the crawler loader through the cameras; and 2, carrying out real-time calculation and analysis on the image to obtain a rotation angle, a pitching angle, a lifting height and a front-back telescopic distance of the crawler loader. According to the invention, a sensor does not need to be mounted on the crawler loader so that the problems that the sensor is difficult to overhaul and the detection precision, stability and reliability of the sensor are influenced due to frequent action and vibration of the crawler loader during working are well solved and avoided.

Description

technical field [0001] The invention relates to the metallurgical industry, in particular to a detection and calculation method for four-dimensional movement position parameters of a slag removal machine. Background technique [0002] For the detection of the rotation angle, pitch angle, lifting height and front and rear telescopic distance of the slag scraper, the main technical method at present is to directly detect by installing sensors on the slag scraper body, including but not limited to installing encoders on the rotating shaft, Install an inclination sensor on the slag removal arm, a position sensor in the hydraulic cylinder, etc. The slag remover is usually installed in a harsh environment full of high temperature and metal dust; the slag remover moves frequently and vibrates greatly during operation, which is very detrimental to the detection accuracy, stability and reliability of the sensor. In addition, once the sensor installed in the oil cylinder fails, it is...
