Abstract


As coal production safety get more and more attention by country and society, the safety monitoring system is used widely in coal mine. A transport mechanism used for the route inspect system of belt conveyor of inclined shaft in coal mine is developed in this paper. The route inspect system can be installed on the platform of the transport mechanism for real time monitoring the belt conveyor, as well as the video, audio and smoke in the inclined shaft of coal mine.According to the actual condition of a coal mine where the transport mechanism is used and the requirements for the mechanism, a solution of the transport mechanism is proposed: a car which carries the monitoring system is pulled by a driving system along a rail backwards and forwards.Several kinds of transport mechanism with different structures and rails are proposed. Also, the 3D models of these transport mechanism are built. Through analysis and comparing the performance of every mechanism proposed, the transport mechanism with cold bending equilateral channel is chosen as the final scheme of transport mechanism. In order to exam the performance of this transport mechanism, a test bench is set up.Based on the final scheme proposed, the structure of the transport mechanism with cold bending equilateral channel rail is designed, as well as the hanging mechanism, the traction mechanism, the car, the brake mechanism, the tension mechanism, the support and steering mechanism, the damping mechanism. The influence of these mechanisms on the performance of transport mechanism is discussed specifically.In addition, the deformation and stress of cold bending equilateral channel rail are calculated and analyzed by ANSYS, which provide a rule for design the length of each rail, the interval between two hang points of the rail. Also the calculate results help designer how to design to improve the mechanical performance of the rail.Finally, the results of research are concluded and further study is forecast.
