Abstract
The utility model relates to a back-up roll changing device, which comprises a shaft, wherein one end of the shaft is connected with a roller through a connecting piece; a balance weight is mounted at the other end of the shaft; two ends of the balance weight are locked by a first locking plate; a hanger is arranged at a middle pivot of the shaft; two ends of the hanger are locked by a second locking plate; and a handle is mounted on one side of the balance weight and located on the shaft through a fastener. By virtue of the equilibrium principle, the balance weight is mounted on the shaft to balance the two ends of the shaft. The roll changing is conveniently realized by a traveling crane hanging movement manner at the pivot. The back-up roll changing device is simple in the operation, low in the cost and high in the efficiency.
Description
Technical field
The utility model relates to the milling train auxiliary equipment in the metallurgy industry, especially a kind of backing roll changing rig.
Background technology
In metallurgical production, milling equipment is when work, and roller system generally all is comprised of backing roll, intermediate calender rolls, working roll etc., is the important component part of milling equipment, and the roll in the roller system always will bear direction and the big or small roll-force effect that is all changing.And the long-term use of roll can produce fatigue wear, perhaps damages, and then needs breaker roll to safeguard or change, artificial and the driving of the available technology adopting push-and-pull that cooperatively interacts realizes, but because roll quality is large, usually be difficult to realize, and have larger potential safety hazard.
The utility model content
The applicant for roll change difficulty in the above-mentioned existing production technology, have the shortcoming such as potential safety hazard, provide a kind of rational in infrastructure, easy to operate backing roll changing rig is convenient to roll change, has reduced potential safety hazard, roll change efficient is high.
The technical scheme that the utility model adopts is as follows:
A kind of backing roll changing rig comprises axle, and an end of described axle is connected with roller by connector, and the other end of described axle is equipped with balance weight, and the two ends of described balance weight are by the locking of the first locking plate; Fulcrum place, described axle middle part is provided with suspender member, and the two ends of described suspender member are by the locking of the second locking plate, and described balance weight one side also is positioned on the axle and by securing member handle is installed.
As further improvement in the technical proposal:
Described balance weight top is equipped with hanger.
The beneficial effects of the utility model are as follows:
The utility model is installed the two ends balance that balance weight makes axle by equilibrium principle on the axle, the method by fulcrum place driving suspended mobile has realized roll change easily, and it is simple to operate, and cost is low, and efficient is high.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the part top view of Fig. 1.
Wherein: 1, handle; 2, the first locking plate; 3, hanger; 4, balance weight; 5, axle; 6, the second locking plate; 7, suspender member; 8, connector; 9, backing roll.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As depicted in figs. 1 and 2, the backing roll changing rig of present embodiment comprises axle 5, and an end of axle 5 is connected with backing roll 9 by connector 8, and the other end of axle 5 is equipped with balance weight 4, and the two ends of balance weight 4 are by 2 lockings of the first locking plate; Fulcrum place, axle 5 middle part is provided with suspender member 7, and the two ends of suspender member 7 are by the locking of the second locking plate 6, and balance weight 4 one sides also are positioned on the axle 5 and by securing member handle 1 are installed, and handle 1 makes things convenient for workman's auxiliary operation; Balance weight 4 tops are equipped with hanger 3, and are convenient with its lifting and installation.
Balance weight 4 described in the utility model can move axially along axle 5, and suspender member 7 can move axially along axle 5, adjusts the position of balance weight 4 and suspender member 7 according to the difference of use occasion.
In the actual use procedure, backing roll generation fatigue wear in milling equipment, when needing maintenance or replacing, respectively with balance weight 4, suspender member 7 is installed on the axle 5, then balance weight 4 will be installed, the axle 5 of suspender member 7 is connected with backing roll 9 by connector 8, according to the weight of backing roll 9, adjusts the position of balance weight 4 and suspender member 7, make axle 5 be in poised state, and finding position of the fulcrum locking suspender member 7, traveling crane plays suspender member 7, provides power mobile axle 5 by driving, the operator can hand handle 1, the auxiliary operation roll change namely can be removed stage makeup and costume backing roll 9 easily by said method, and is simple to operate, cost is low, and efficient is high.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range within protection domain of the present utility model, can be done any type of modification referring to claim.
