Underground Mining Scraper Winch is a mechanical conveying device for fixed equipment. It is mainly used for continuous vertical lifting of powder, granular and small materials. It can be widely used in feed mills, flour mills, rice mills and oil mills of various scales. The improvement of bulk materials in starch factories, grain depots and port terminals.
The Underground Mining Scraper Winch is divided into two types: the Tower Mining Underground Mining Scraper Winch (the machine room is located on the top of the wellbore) and the Underground Mining Scraper Winch (the machine room is directly on the ground). According to the number of hoisting ropes, it is divided into the single rope friction type Underground Mining Scraper Winch and the multi rope friction type Underground Mining Scraper Winch. The advantage of the latter is that a thinner steel wire rope and a friction wheel with a smaller diameter can be used, so that the unit has a small size and is easy to manufacture; the speed is high, the lifting capacity is large, and the safety is good. Most of the shafts with an annual output of more than 1.2 million tons and a depth of less than 2,100 meters use this Underground Mining Scraper Winch.
The motor itself is not rotating properly, and the rotor is removed to check the static balance. The accuracy of the reducer and the motor is poor, and the alignment is over-regulated. The motor base is not installed accurately enough, and the level exceeds the specification and is re-adjusted. The drive sprocket is installed with an error and needs to be re-adjusted.
The full-length flange of the casing is damaged or leaking. Replace the new gasket, apply sealant, and retighten the flange bolts. The material is discharged from the gap between the machine head and the base, and the gasket or sealant is added. The height difference of the input materials is too large, the feeding pressure is increased, the material input method needs to be changed, and the buffer device for feeding is increased. The amount of lifting is not up to the design capability, the material is bonded to the chain bucket and the slipper, and the material is periodically removed according to the degree of bonding.
