Research And Application Of Train Self-moving Technology For Heavy Equipment In Large Fully Mechanized Mining Face

At present,the mining equipment in the fully mechanized coal mining face tends to be automatic,intelligent and unmanned.However,the mobile substation,pump station and other equipment that provide power for the fully mechanized coal mining face still use a large number of rail winch wire rope traction mode for transportation,which has the potential safety problems of low transportation efficiency,high labor intensity,easy to fall off,sports car and so on.The above problems restrict the production and capacity expansion of the fully mechanized coal mining face Safe and efficient mining.In view of the above situation,this paper puts forward a technical scheme of self-moving heavy equipment train,which realizes the sate and efficient self-moving of heavy equipment in the main transportation lane of fully mechanized mining face,and solves the hidden dangers and short boards of transportation existing in the traction equipment train of the back column winch in fully mechanized mining face.Based on the analysis of the application status of trackless and trackless trains,combined with the geological conditions of 12316 working face and the actual conditions of roadway in daliuta coal mine,the research purpose,content and route of this paper are put forward.The working principle and structural design of the self-moving train are described in detail,and the hydraulic system of the train is designed and calculated.The SolidWorks software was used to build the 3d model of the self-moving equipment train and analyze the strength of the key structures.To the industrial test,the results of the study to verify the mining ship along the train move since the technical feasibility of automation equipment,It has been applied in the mines of Shendong coal group,The application results show that compared with the traditional way,the number of workers is reduced by 8,the work efficiency is increased by 11.92%on average,the consumption of materials and accessories is reduced by 33.33%and 16.67%respectively,and the comprehensive economic benefit is 12.08 million.The test results show that the train structure design of the equipment is reasonable and reliable.
