Optimizations of the internal structure of the reel of a double rope winder

Abstract

Due to the shortage of resources, the deep development of resources is imminent, and the superdeep mine hoist plays a leading role in the development process. According to the structure, the hoists can be divided into winding hoists and friction hoists. Winding hoists can be single-rope winding and multirope winding. With the increase of mining depth, friction hoists will have the disadvantage of increasing the mass of the tail rope, while wire rope diameter of single-rope winding hoists will increase with the increase of mining depth. So double-rope winding hoists can be used to balance the above two problems. Therefore, this study will use finite element analysis, and treat hoist reel as a uniformly pressurized shell, through the static and modal analysis of reel. Under the maximum static tension, this study gets the reel the force and deformation distribution. Through the change of the internal structure of the reel, it improves the reel force weakness and reduce the reel deformation. By reducing the deformation of the reel, this study tells how to reduce the tension difference of the wire rope. This study will improve the synchronization and stability of the hoisting system and provide an alternative and effective way for the deep development of the resources with the double-rope winding hoists.
