Description
Technical field
The utility model relates to a kind of provision for disengagement, the special demounting device of tapered sleeve on especially a kind of grinding roller of vertical mill.
Background technology
Tapered sleeve is assemblied between roll shaft conical surface cylindrical and collars inner circle, interference fit is realized by pressurization, in collars assembling, tapered sleeve plays a part connection, the hardness of tapered sleeve, wearability is lower than roll shaft, collars, belong to consumable accessory, when overhauling grinding roller of vertical mill, tapered sleeve is often needed to disassemble, due to firmly interference fit during assembling, cause dismounting very inconvenient, if to dismantle by force and due to quality, the reasons such as installation or Long-Time Service, in unloading process, easily cause tapered sleeve earrings break or produce fatigue crack, to follow-up maintenance, production brings a lot of inconvenience, and present associated detacher device is on the market comparatively heavy, operation and maintenance maintenance itself also comparatively loaded down with trivial details, cost is higher simultaneously.
Summary of the invention
The utility model in order to solve the inconvenient problem of grinding roller rear end tapered sleeve dismounting, provide a kind of structure simple, easy to use, dismantle grinding roller tapered sleeve provision for disengagement fast.
The utility model solves the technical scheme that its technical problem adopts: the provision for disengagement of a kind of grinding roller tapered sleeve, comprise dismounting location-plate, top board, connecting rod and jack, it is characterized in that, described dismounting location-plate and top board are connected and fixed by connecting rod, described dismounting location-plate arranges chucking lug and axis through-hole, described chucking lug is corresponding with the petal platform on tapered sleeve, described jack is arranged between dismounting location-plate and top board, and the push rod of described jack is through the dismounting axis through-hole of location-plate and the end contact of roll shaft.
Further, described connecting rod is uniformly distributed around axle center, and is at least 3.
Further, described connecting rod is double end tapping screw rod, and described top board and dismounting location-plate are provided with the tapped through hole corresponding with screw rod.
Further, pad is provided with between described push rod and roll shaft.
The utility model has structure simple, easy to operate, safe and reliable, provides high and has dismantled the advantages such as the efficiency of tapered sleeve, and the utility model cost is low simultaneously, weight is little, structural reduction, is convenient to the maintenance and repair of itself.

Detailed description of the invention
Be described further below in conjunction with accompanying drawing 1,2,3 pairs of the utility model.
The utility model relates to the provision for disengagement of a kind of grinding roller tapered sleeve, comprise dismounting location-plate 1, top board 2, connecting rod 3 and jack 4, it is characterized in that, described dismounting location-plate 1 and top board 2 are connected and fixed by connecting rod 3, described dismounting location-plate 1 is arranged chucking lug 5 and axis through-hole 6, described chucking lug 5 is corresponding with the petal platform on tapered sleeve 11, described jack 4 is arranged between dismounting location-plate 1 and top board 2, the axis through-hole 6 of push rod 7 through dismounting location-plate 1 and the end contact of roll shaft 9 of described jack 4.
Further, described connecting rod 3 is uniformly distributed around axle center, and is at least 3.
Further, described connecting rod 3 is double end tapping screw rod, and institute's top board 2 and dismounting location-plate 1 are provided with the tapped through hole 8 corresponding with screw rod.
Further, pad 10 is provided with between described push rod 7 and roll shaft 9.
Tapered sleeve 11 is assemblied between roll shaft conical surface cylindrical and collars inner circle, interference fit is realized by pressurization, during dismounting, dismounting location-plate 1 is inserted from the petal platform gap tapered sleeve 11, rotate dismounting location-plate 1, chucking lug 5 is overlapped with tapered sleeve petal platform, then jack 4 and top board 2 is assembled, the height of adjustment jack 4 makes push rod 7 end face of jack and the end contact of roll shaft 9, pad 10 can be added between push rod 7 and roll shaft 9, to reach the effect of rapid adjustment and protection roll shaft, after adjusting, jack is made to start normal work, after reaching certain pressure, tapered sleeve 11 will be pressed down.
