Analysis of the Effect of Impact Force on the Safety Braking Torque of Hoist and Calculation of Oil Pressure Value
Due to the different scale of coal mine production and shaft arrangement,the depth of construction vertical shaft and shaft diameter will be different.In the process of vertical shaft drilling,the gangue task is different,which leads to the continuous change of lifting load,so it is necessary to carry out supporting calculations for the hoist and motor.Therefore,the influence of impact force on safety braking torque in vertical shaft drilling hoisting system is analysed,the relationship between the mass modulus Z of hoisting system and the safety braking torque multiplier K is explored,the method of selecting the value of K is given,and the method of selecting the braking torque and calculating the value of oil pressure for vertical shaft drilling hoisting is proposed.
