W steel belt conveyor of coal mine underground and ground production system is widely used in a continuous action of transportation equipment. The transport force, small resistance, low power consumption, at the same time, transport processes in scattered coal, less fragmentation is small, thereby reducing the loss of coal dust and. One, belt conveyor according to different types of traction, belt conveyor roller drive and can be divided into two types of steel wire rope traction; according to different installation modes, can be divided into hanging type and a floor type two; according to the moving mode is divided into fixed and retractable type two.
In 1, a fixed belt conveyor this conveyor is characterized in that the machine frame is fixed on the floor or on the basis of W steel strip used for inclined shaft, the main roadway, and coal preparation plant.
In 2, hanging belt conveyor this conveyor is characterized by a conveyor roller and the intermediate portion has indeed lower roller hanger are arranged in two parallel steel wire rope, wire rope and the lower roller and sling hanging on a top beam. Its fuselage height can be adjusted, and can adapt to the floor is uneven, roadway water conditions, can be used for working face smooth grooves and the mining area on the mountain, for the transport of.
In 3, W steel belt conveyor this conveyor is long distance, large conveying capacity, long service life of W steel strip, can take a person, and the smooth transportation conveyer, which is suitable for the large and medium-sized mine service life longer, can be inclined and horizontal transport, but not suitable for the transport of slurry containing more materials.
In 4, the telescopic belt conveyor in fully mechanized working face advancing, faster speed, W strip coal transport distance with the trough length change. This requirement shall be trough transport equipment can be shortened or elongated flexible quickly. Telescopic belt conveyor in order to fit the above requirements, and set up a belt storage bin and a set of belt storage device. This set of device to temporary storage amount of the function of a conveyor belt, when the mobile tail of the telescopic belt storage device, can be released or storing a length of conveyor belt. W strip mounted conveyor belt speed should not be greater than 2.5 m / s, W strip of the large block, wear resistant materials should use a fixed force type discharging device, should be used in low speed. Conveyer conveyor belt transmission roller diameter and the relationship between layers, drive roller, supporting roller and a pair of brackets to corner requirement should be based on the conveyor belt design, reasonable selection of. Tape by feeding section should shorten the distance between rollers and the buffer roller, to prevent the leakage of materials, W strip with side should be the appropriate block board, lest the baffle plate is excellent, scrape conveyor belt surface, W steel feed range should comply with the tape running direction, to reduce the material of the whereabouts of tape impact should use the chute, reduce the material falling distance.
