Abstract

The invention relates to a vertical mill roller sleeve dismounting and mounting device and a vertical mill roller sleeve dismounting and mounting method applying the same, and relates to the field of vertical mill equipment. The vertical mill roller sleeve dismounting and mounting device is used for dismounting and mounting a mill roller and a mill sleeve, the mill sleeve is connected to the outer side of the mill roller in a sleeving mode, a jack is placed on the upper surface of the mill roller, and a connecting plate is placed on the upper surface of the jack. A plurality of connecting rods are fixedly connected in the circumferential direction of the connecting plate, a hanging rod is connected to the lower end of each connecting rod, a hanging groove is formed in the side face, close to the mill sleeve, of each hanging rod, the mill sleeve is inserted into each hanging groove so as to be connected with the hanging rods in a hanging mode, and a lifting machine is connected to the surface, away from the milling sleeve, of the connecting plate. The device has the effect that the vertical mill roller sleeve is convenient to dismount.

Description

technical field [0001] The present application relates to the field of vertical mill equipment, in particular to a vertical mill roller sleeve dismounting device and a vertical mill roller sleeve dismounting method using the device. Background technique [0002] As a main grinding equipment, the vertical mill is widely used in grinding raw materials, cement, coal powder and other occasions. The vertical mill has stable mechanism performance, high abrasive efficiency and long service life. The vertical grinding roller sleeve includes a grinding roller and a grinding sleeve. The grinding sleeve is sleeved on the outside of the grinding roller, and the grinding roller and the grinding sleeve are in interference fit. The grinding roller and the grinding sleeve need to be disassembled regularly for maintenance. Since the grinding sleeve plays an important role in the abrasive, it is inconvenient to drill holes on the grinding sleeve to install lifting rings, so as to reduce the ...
