Discussion on function realization and simulation model of mine rescue winch

In order to transport the trapped people or equipment to the ground timely and safely in mine safety accident rescue process,it was proposed that the rescue winch should have the additional functions of stable operation,real-time monitoring and easy control.This paper mainly discussed the way to realize the function of rescue winch.By setting up automatic rope-arranging mechanism and rope-pressing mechanism,the winch rope-arranging stability could be realized.By setting up automatic weighing element and automatic depth-measuring element,the winch weighing and depth-measuring functions could be monitored in real time.By setting up hydraulic system,the winch could achieve good lifting performance and stable operation control.The hydraulic-mechanical joint simulation model of rescue winch was established by using AMESim software to simulate the action logic of hydraulic control of rescue winch. The function of rescue winch was discussed,and the feasibility of implementation was explored.The simulation model could show the power system of the winch and provided a reference for the design and system analysis of the rescue winch.
