Research And Application On Safety Hold-on Cage Device Of Auxiliary Shaft Hoisting System In Xin An Mine

According to the preliminary statistics,the vertical shaft mining mode accounts for a large proportion in China's mine production,and the friction hoisting system is adopted by most of the vertical shaft mining because of its stability.As the main transportation mode of "traffic artery" in deep coal mining,the mine hoisting system is an important part of coal mine safety production.The efficiency and safety of the mine also promote the safe and efficient mining.According to the analysis,the wellhead loading and unloading time is one of the main bottlenecks that affect the efficiency.Therefore,the main task of this project is to research and design a new safe tank stabilizing device to shorten the loading and unloading time,improve the efficiency,eliminate the hidden danger of overload and ensure the safety,which has great social and economic benefits.According to the actual needs of the project,the weight of the auxiliary loading and unloading device is estimated to be low,which leads to the long time of manual operation.Taking the mine friction hoisting system as the basic material of engineering research,through the field investigation and statistical analysis of the auxiliary shaft hoisting system in Xin'an mine,the reliability diagram is constructed by using the reliability theory analysis method,and the key factor of low efficiency of the system loading and unloading device is intuitively obtained,which provides the theoretical basis and design standard for the design of the safe and stable tank device in the mine.In this project,the pre hazard analysis and operation condition hazard evaluation method are selected to evaluate and analyze the hazard of the device.The mechanical knowledge is used to analyze and study the structure of the device,find out the characteristics of the stress law,and build the stress model.This paper introduces the structure of the safe tank stabilizing device and the reliability of the distribution device.Through the collection and analysis of on-site data of Xin'an mine system,the conclusion is used as the basis for the design of the device to meet the needs of mine production,and the stress and strength of the key unit components are analyzed by the finite element method.Then the prototype is manufactured,the components of the test device and the functions of the whole machine all achieve the design objectives.The application of the designed product in the auxiliary shaft of Xin'an mine shows good effect,meets the requirements of mine production,and has obvious safety and economic benefits.The research device of this topic has a fundamental solution to improve the efficiency and reduce the occurrence of accidents,and has a great significance to promote the upgrading of domestic mine safety technology.There are 41 pictures,12 tables and 55 references.
