Introduction
With the development of the mining industry, coal mining machines have been widely used in coal production. Mastering the operating status of coal mining machines is important for ensuring high coal production.
High efficiency plays an important role. The current measurement technology of shearer electrical and hydraulic aspects is relatively mature, but the shearer mechanical measurement technology is lacking.
Test technology. The formulation of this standard aims to solve the problems of backward R&D and test methods of coal shearers and the disconnection between basic research and engineering technology development.
Break the technical bottleneck of "theory is not supported, the design is based on experience, the verification is based on the site, and the development of each stand-alone machine is not balanced".
The development direction of humanization and intelligence.
Through the statics, kinematics, dynamics analysis and real-time measurement of the operating state of the drum shearer, the mechanical performance measurement of the drum shearer is formed.
Test principles, test conditions, instruments and equipment, test methods, data analysis and processing, and guide the development, use, inspection and testing of coal shearers
significance.
This series of standards is applicable to various types of drum shearers, forming a scientific, standardized, and applicable testing method for the mechanical performance of shearers.
Standards are conducive to the high-yield, high-efficiency, safe and reliable mining of my country's coal mines, as well as prolonging the service life of shearers and reducing maintenance costs.
Testing method of mechanical performance of drum shearer
Part 1.Laboratory test
Caution-The personnel using this standard should have practical experience in formal laboratory work. This standard does not point out all possible safety issues
question. The user is responsible for taking appropriate safety and health measures and ensuring compliance with the conditions stipulated by relevant national laws and regulations.
