Abstract
The utility model discloses a rolling mill lifting device which comprises a saddle provided with a T-shaped through groove and a T-shaped slide rail matched with the T-shaped through groove. The slide rail is connected with a lifting horizontal beam through three connection members, and each connection member comprises a screw, a buffer, a lifting oil cylinder, a pin and a lifting horizontal beam suspension seat. The rolling mill lifting device is an efficient, quick, safe and reliable rolling mill backing roller system lifting device, greatly saves roller change time and greatly improves production efficiency.
Description
Technical field
The utility model relates to a kind of milling train lifting device.
Background technology
MKW mill is a kind of cold-rolling mill of minor diameter working roll structure uniqueness, is the multi-roll mill of working roll being set up the side bearing roller on the four-high mill basis of backing roll transmission, and MKW mill just can satisfy rolling strip as multi-roll mill like this.Its design feature is that a whole set of working roll, intermediate calender rolls and side bearing backing roller system are installed on the supporting arm of the axis rotation of lateral-supporting roller.The vertical force that backing roll bears when rolling is passed through depress oil cylinder, pass to frame, the side force of side backing backing roll system also passes to frame by the backing saddle, when the contacting of side backing roller system and backing roll adopted spring to keep to be backing roll to promote, backing roller system also was subjected to the and then lifting of power of spring simultaneously.
Side backing roller system is by two saddles, intermediate calender rolls, working roll, back lining bearings form up and down.There are two suspension ring saddle top, and suspension ring (ear) link to each other with crossbeam in the mill housing by screw rod, and the other end of screw mandrel is equipped with spring.All will remove the parts such as spring, pin, bolt when each replacing backing roller is can remove roller system one by one.Consuming time dangerous again, be easy to parts damages, cause production efficiency to descend.
The utility model content
The utility model overcomes the deficiencies in the prior art, and efficient, quick, a safe and reliable milling train lifting device is provided, and specifically milling train backing roller is lifting device, has greatly saved roll changing time and production efficiency.
A kind of milling train lifting device that the utility model provides comprises the saddle with a T-shape through slot, the T-shape slide rail of a described T-shape through slot size of coupling; Described slide rail is connected with a lifting crossbeam by three connecting elements, and each described connecting elements comprises screw rod, buffer, lift cylinder, pin, lifting crossbeam hangoff receptacle.
Further, described lifting crossbeam is fixed on the inboard of mill housing, and the hanger of described lift cylinder bottom links to each other by pin with lifting crossbeam hangoff receptacle.
Coming into operation of the utility model milling train lifting device saved roll changing time and production efficiency greatly, by till now 2 hours of more than 4 hour time shorten of original each roll change with the interior time.Hydraulic lifting apparatus is so that the installation of workpiece is more accurate convenient, and accident rate is low, safe and reliable.Saved the process of cumbersome dismounting screw.Can reconcile according to different needs simultaneously the position of backing roller system in the production process, satisfy demand when changing working roll and threading.Has the reliability height, energy-conserving and environment-protective, the advantages such as long service life.
Description of drawings
Fig. 1 is the partial structurtes schematic diagram of the milling train lifting device that provides of the utility model.
Fig. 2 is another partial structurtes schematic diagram of the milling train lifting device that provides of the utility model.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, 2, a kind of milling train lifting device that the utility model embodiment provides comprises 1, one the T-shape slide rail 2 that mates described T-shape through slot size of saddle with a T-shape through slot; Described slide rail is connected with a lifting crossbeam 3 by three connecting elements, and each described connecting elements comprises screw rod 4, buffer 5, lift cylinder 6, pin 7, promotes crossbeam hangoff receptacle 8.
Further, described lifting crossbeam is fixed on the inboard of mill housing, and the hanger of described lift cylinder bottom links to each other by pin with lifting crossbeam hangoff receptacle.
Concrete structure improves in following place: 1, the T-shape slot of upper saddle seat processing in backing roller system runs through whole saddle, reprocesses a T-shape slide rail, penetrates in the T-shape slot on the saddle.2, three hydraulic lift(ing) cylinders of manufacture and three buffers are used for connecting backing roller system and promote crossbeam.3, track with the turnover of backing roller system of manufacture.4, manufacture one cover frock is used for fixing of whole backing roller system.
According to length and the room for promotion of lift cylinder, at first will be fixed on for the crossbeam that promotes the inboard of mill housing.With the hanger of lift cylinder bottom with promote the crossbeam hangoff receptacle and link to each other by pin, the piston rod outer end with oil cylinder links to each other with buffer again, the screw rod of buffer inside with just form a hydraulic lifting integral after a connecting hole on the T-shape slide rail links to each other.After lifting device installs, the T-shape slide rail is packed in the T-shape chute on the saddle.After the Hydraulic Station energising, hydraulic lifting apparatus just can move flexibly, again the upper saddle seat in the backing roller system is mentioned, the upper and lower saddle of packing into connect support after, upper saddle seat is put down, be loaded into and fix being connected of working roll and saddle carrying out in advance frock.At this moment be to mention the mill train of putting into the turnover of supporting backing roller system with whole backing, whole roll change promotes the turnover process and has just finished.
Claims (3)
