Tunneling machine body posture parameter measurement technology won the national patent

The new advanced technology of “body parameters measurement method and method for boring machine” jointly developed by China University of Mining & Technology (Beijing) and Hebei Suizhong Energy Shijiazhuang Coal Mining Machinery Co., Ltd. Bureau granted invention patents. The invention has been successfully applied to the automatic cutting and forming machine used in the research of the National 863 Key Project “The Remote Control Key Technology for Coal Mining Equipment”. The boring machine was actually used in the Wusu Coal Mine in Guanban, Inner Mongolia, creating a 1262-meter-year tunneling and annual footage. A record of over 10,000 meters. The invention provides powerful technical support for realizing the mining of unmanned working face in coal mines.

According to the introduction of the technical personnel of the Stone Coal Machinery Company, the “Key Remote Control Technology for Mining and Mining Equipment” of the National 863 Key Project jointly undertaken with the Mines is to realize the remote control and monitoring of coal mining equipment, and then to realize the mining of the unmanned working face of the mine. In the original technology, the driver of the roadheader visually measures the position and posture of the fuselage, the position is inaccurate, the over-excavation and under-digging are serious, and the roadway control accuracy is low. In order to realize real-time automatic adjustment and excavation of the roadheader posture, the mining companies jointly took the road of production, research and development to form a research group. After repeated demonstrations of the feasibility and advantages and disadvantages of the existing technologies at home and abroad, the research team has continuously researched and designed, repeatedly trial-produced samples and improvements, and finally jointly created and invented a “tender machine body posture parameter measurement system with extremely high practical value”. And its methods."

The invention can real-timely measure the multi-angle pose parameters of the boring machine body through the combination of line laser transmitters, programmable computer controllers, tilt angle sensors and Other electronic components, and the error of the body deflection angle, pitch angle and roll angle obtained is less than 0.1 degree, biased displacement error is less than 5 cm. In coal roadway excavation process, these posture errors are automatically corrected by a programmable computer controller, and high-quality roadways that meet the design parameters of the coal roadway are obtained.

The technical personnel of the research group introduced that the equipment used in the invention is simple and practical, with high accuracy, good real-time performance, and easy installation and adjustment, and it is an essential technical condition for realizing remote control of the roadheader and remote remote visualization. The remote remote boring machine developed by relying on this technology can greatly reduce the labor intensity of underground workers, improve the quality of roadway forming and the speed of excavation, provide safety for the construction of coal roadways, and finally provide a guarantee for the unmanned working face of underground mines.

The patent certificate states that: Compared with the prior art, the present invention has obvious advantages and effects, has considerable technological advancement and practicality, and has extensive industrial use value.
