Stacker-reclaimer remote control system

Abstract

The invention belongs to the field of mining industry, and discloses a stacker-reclaimer remote control system. The system comprises a data processing device, a laser scanning device, a PLC control system, a pitching positioning device, a level gage and a stacker-reclaimer swing mechanism positioning device. The laser scanning device, the PLC control system, the pitching positioning device, the level gage and the stacker-reclaimer swing mechanism positioning device are all connected with the data processing device; a three-dimensional coal pile model is generated according to the coal pile scanning information; and the system is further used for obtaining a material piling and taking task and generating a stacker-reclaimer control signal according to the material piling and taking task, the real-time pitching angle of a material taking arm, the rotation angle of a material piling arm and the material taking arm, the material piling height, the material taking height and the material level distance, and the PLC control system is used for controlling the stacker-reclaimer to complete the material piling and taking task according to the stacker-reclaimer control signal. The unattended operation of the stacker-reclaimer in a coal yard can be realized, the investment of labor cost is reduced, and the personal safety is guaranteed.

Description

technical field [0001] The invention belongs to the field of mining and relates to a remote control system for a stacker and reclaimer. Background technique [0002] The stacker-reclaimer is a large-scale coal yard machinery equipment for continuous reclaiming and stacking. It is mainly composed of a metal frame, a stacking belt, a stacking arm, a reclaiming scraper and a slewing device. The stacking arm can rotate 360° to store the raw coal of the coal handling system in front of the warehouse in different positions in the circular storage yard; the reclaiming scraper can transport the raw coal at any position in the storage yard to the loading system behind the warehouse. Cooperate with the loading station to complete the entire loading process. [0003] Traditional stacker-reclaimer operation is performed manually by the stacker-reclaimer driver on site, and the production relies heavily on the stacker-reclaimer driver's operating technology. At present, there are the f...

AI Technical Summary

Problems solved by technology

At present, there are the following problems: 1. The labor intensity is high, and there are relatively large dust, noise and other hazards in the silo, which brings serious physical and mental burdens to the stacker-reclaimer personnel; 2. At night, the dust concentration is relatively high. 3. When stacking manually, the stacking height may be different, which wastes the space in the warehouse or the stacking height exceeds the limit. Causing safety accidents; 4. It is difficult to select the entry point for material reclaiming during manual operation, which may lead to uneven reclaiming and affect the safe and stable operation of the entire coal conveying system
