Experimental Study on the Optimization of Mine Hoisting Machine Electromechanical Braking System
In order to meet the braking response requirements of coal mine hoist,a new type of mine hoist electromechanical braking technology is proposed,the principle of mine hoist electromechanical braking is demonstrated,the detailed parameters and braking performance of electromechanical brake are given,and a large-loaded and high-response electromechanical brake test platform is developed.Experiments show that the designed electromechanical brake can reach a maximum positive pressure of 33 kN,which meets the positive pressure requirements of the mine hoist.The braking error is less than 10％,and the braking gap elimination time is less than 0.1 s.There is a linear relationship between the motor current input and the brake positive pressure output,with a slope of 4.17 and an intercept of 0.3;the screw displacement output is in a cubic relationship with the brake pressure output,and the zero error is small.Through the optimization experimental study of mine hoist electromechanical braking system,it can provide new ideas for the development of coal mine hoist electromechanical brake.
