Multi-stage operating speed adjusting device and method under automatic cutting mode of coal cutter

Abstract

The invention discloses a multi-stage operating speed adjusting device and method under an automatic cutting mode of a coal cutter. The multi-stage operating speed adjusting device comprises a coal cutter control module and a handheld-type adjusting module. The handheld-type adjusting module comprises a handheld controller, a speed input key, a liquid crystal display, an alarming module and a first indicator lamp. The coal cutter control module comprises a coal cutter controller, a second wireless receiving and transmitting module and a storage. The input end of the coal cutter controller is connected with a speed detecting module, a traveling direction detecting module, a position detecting module and a speed threshold value input key module, and the output end of the coal cutter controller is connected with a coal cutter traveling motor and a second indicator lamp. The multi-stage operating speed adjusting method comprises the following steps of 1, detection for the current positionof the coal cutter; 2, judgment on the current position of the coal cutter and adjustment for the operating speed of the coal cutter; and 3, real-time detection and transmission for the operating speed of the coal cutter. According to the multi-stage operating speed adjusting device and method, design is reasonable, the operating speed of the coal cutter under the automatic cutting mode can be adjusted, optimal speed control over automatic coal cutting is achieved, and the practicability is high.

Description

technical field [0001] The invention belongs to the technical field of remote speed adjustment of coal shearers, and in particular relates to a multi-stage operation speed adjustment device and method in the automatic cutting mode of coal shearers. Background technique [0002] At present, the technology of coal mining machines at home and abroad is changing with each passing day. Automated, intelligent, and unmanned fully mechanized mining face is no longer a dream, but has gradually turned ideas into reality. Due to the continuous improvement of customers' requirements for the function of shearers, the competition in the industry has become increasingly fierce, and the R&D personnel of various companies have racked their brains to innovate designs, resulting in the rapid improvement of shearer technology, continuous increase in functions, and more stable performance, but there are still technical blind spots. At present, the shearer can realize automatic coal cutting, but ...

AI Technical Summary

Problems solved by technology

At present, the shearer can realize automatic coal cutting, but in the automatic cutting mode, the operating speed of the shearer is fixed according to the parameter setting, and the shearer cannot be changed according to the real-time conditions of the coal mining face during the operation of the automatic cutting mode Running speed, unless there is human intervention, but in this case, the automatic coal cutting mode will no longer be run, and it will become a manual control coal cutting mode
