1.引言煤矿可伸缩带式输送机正朝着大运量、长距离、大功率、高速度方向发展。由于输送机的单机长度不易过长,只能通过中间驱动技术来解决长距离、大运量输送问题。中间驱动技术与软起动技术的选择,直接影响到可伸缩带式输送机运行的可靠性和经
1. Introduction Coal mine telescopic belt conveyor is moving in large capacity, long distance, high power, high speed direction. As the conveyor length is not easy to stand-alone machine, only through the middle drive technology to solve long-distance, large capacity delivery problems. The choice of intermediate drive technology and soft start technology has a direct impact on the reliability of the retractable belt conveyor operation and
