Research on intelligent CT detection of drill pipe fracture in coal mine tunnel drilling

In the process of production and processing of coal mine drill pipe,due to the poor processing,production,manufacturing and other processes,the drill pipe itself has quality problems such as gaps,inclusions,cracks,defects and uneven density.In the process of drilling the coal mine drill pipe in the underground,the drill pipe is affected by the complicated external force of the drill pipe,which often causes the drill pipe to break due to the quality problem of the drill pipe itself,thereby hindering normal production and causing major economic losses.In response to these problems,the traditional industrial CT detection method can effectively detect the quality problems such as pores,cracks,gaps and defects in the drill pipe body,thereby improving the processing technology of the drill pipe and the quality of the finished product.However,in the traditional CT inspection process of drill pipe,the method of manual assembly and unloading of the drill pipe is used for loading and unloading,which has the disadvantages of low detection efficiency,low profit,and weak automation,which cannot meet the requirements of intelligent development of coal mine equipment.On this basis,the intelligent robot system,pipeline scanning technology and servo motion control are introduced into the drill pipe industrial CT detection system.The detection system mainly consists of image analysis software,electrical control software,ray source system,detection and detection system,and motion servo system,intelligent robot and its control system,pipeline scanning system and security protection system.Using the upper and lower two-layer control structure,the intelligent manipulator and its control system are used as slave stations and the motion servo system is configured as the master station.The upper computer software is used to control the operation and action of these underlying systems to realize intelligent drill pipe CT scanning,fault analysis and structural testing.Therefore,the time for manual loading and unloading can be greatly shortened,the efficiency of the drill pipe detection and the detection process can be enhanced,the drill pipe equipment can be intelligently,safely and efficiently carried out,thereby improving the process flow of the drill pipe processing，production and improving the drill pipe body quality.
