Belt conveyor has the advantages of large installation capacity, long transportation distance, simple equipment structure, convenient maintenance and long service life. It can be used as horizontal transportation and inclined shaft hoisting, and is an important equipment for mine production hoisting and transportation. The frame is used to install idlers. There are two types of racks: hanging type and floor type. Floor type is divided into fixed type and detachable mobile type. The fixed universal belt conveyor used for the main transportation roadway on the ground and underground belongs to the floor type fixed frame. It is fixed on the foundation of the conveyor roadway, which is firm and stable and has a long service life; the belt conveyor used for the roadway in the mining area , Due to frequent movement, detachable mobile floor racks or hanging racks are generally used. There is no bolt connection between the frame and the frame and between the frame and the idler, but the connection method of insertion and hook is adopted, and the pin is positioned, which can realize fast installation and disassembly.
