Abstract:

Due to the particularity of geological conditions in Yunnan - Cuizhou Plateau coal mine, super large dip Angle down belt conveyor has become the main equipment for underground raw coal transportation, so higher requirements are put forward for the safety, stability and continuity of raw coal calculation equipment. This paper presents a safety protection device for belt, idler, idler, brake and electronic control system of downward belt conveyor with large dip Angle. The device is composed of programmable control box and mine flame - proof power box, and can be combined with motor, mine vacuum switch, signal system all kinds of protection sensors to form conveyor electronic control system.The device can effectively improve the design and manufacturing level of the belt conveyor with large dip Angle. At present, the device has been applied in some coal mines and achieved good results.
