Description

High-wind-pressure rock drilling tooth performance test method, system, storage medium and equipment based on noise analysis Technical Field The invention relates to the technical field of performance test of mine rock drilling tools, in particular to a high-wind-pressure rock drilling tooth performance test method, system, storage medium and equipment based on noise analysis. Background In engineering projects such as modern large-scale infrastructure construction, mineral resource exploitation, the high wind pressure button is widely used in drilling operation, is the key consumptive material of guaranteeing that the construction goes on smoothly. With the continuous expansion of engineering scale and the increasing complexity of construction environment, the performance requirements on the high wind pressure spherical teeth are more stringent. On one hand, the high-efficiency rock breaking capability of the spherical teeth under the working conditions of strong impact, high abrasion is required due to large differences of factors such as rock hardness, geological conditions and the like, and on the other hand, the spherical teeth are required to have long service life and high reliability in order to improve the construction efficiency and reduce the cost. At present, the high wind pressure spherical tooth working performance identification method has obvious defects. The traditional detection mainly relies on manual appearance inspection, and the conditions of abrasion, cracks and the like of the surface of the spherical tooth are judged through experience, so that subjectivity is high, internal fine defects are difficult to find, and potential performance problems of the spherical tooth cannot be accurately estimated. Although the hardness test can reflect the surface hardness of the material, the comprehensive performances of impact resistance, wear resistance, fatigue life and the like of the spherical tooth under the actual complex working condition cannot be reflected. When the simulation working condition is tested, the existing means are difficult to truly restore extreme working environments such as high wind pressure, strong impact, changeable rock characteristics and the like, so that the deviation between the test result and the actual working performance is larger. In addition, the identification methods are mutually independent, lack of system integration, and cannot provide a comprehensive, accurate and mutually verified evaluation system for the performance of the spherical teeth, so that sufficient scientific basis is lacked in the research and development of the spherical teeth, quality control and selection application, and the engineering construction efficiency and quality improvement are seriously restricted. Therefore, development of a scientific, comprehensive and accurate high-wind-pressure button working performance testing method is needed. Disclosure of Invention Based on the above, the invention aims to provide a high wind pressure rock drilling tooth performance test method, a system, a storage medium and equipment based on noise analysis, so as to fundamentally solve the problem that the current means are difficult to truly restore extreme working environments such as high wind pressure, strong impact, changeable rock characteristics and the like, and the deviation between test results and actual working performance is larger.
