Mine Winch Traction Frequency Conversion Device Optimization
IIn the view of the problems of difficult fixing mode and single speed regulation mode,the optimization scheme of mine winch in Zhenchengbottom coal mine is designed.The mechanical structure of mine winch is optimized according to the working condition of fully mechanized pullback face in Zhenchengdi coal mine,and the working condition of pulling hydraulic support for pullback face is satisfied.Variable frequency control device is added to realize dynamic and real-time adjustment of traction speed.Finally,the practical application is completed.The application results show that the optimized mine winch can meet the working condition of fully mechanized mining pullback surface,the fixed way is safe,it is not easy to cause the winch frame deformation,the traction frequency conversion speed regulation is realized,and the underground operation safety factor of mine winch is enhanced.
