Description

A kind of planisher backing roll lifting device
Technical field
The utility model relates to steel plant's cold rolled continuous annealing unit hanging device, particularly a kind of planisher backing roll lifting device that is used for the replacing of planisher backing roll.
Background technology
The planisher equipment of steel plant's cold rolled continuous annealing unit is provided with up and down backing roll, intermediate calender rolls and six rollers of upper working rolls and lower working rolls up and down.Planisher is provided with changing rig, can realize the quick replacing of working roll, intermediate calender rolls and backing roll.After the old roller of the backing roll of planisher shifts out frame by roll change buggy, need lifting to transport, and then the backing roll that more renews.
Fig. 1 is the scheme drawing of planisher backing roll, as shown in the figure, bearing seat 101 meeting handlings together when changing at the two ends of planisher backing roll 100, usually the mode of lifting is, manually load onto hanger in the both sides of last planisher backing roll 100 both sides bearing seats 101, manually hang steel rope again on hanger, hang away by driving again.New roller by the driving handling behind the roll change position, behind artificial receipts steel rope, again by the hanger of the both sides of manually unloading backing roll 100 both sides bearing seats 101.In actual roller replacing operation process, because of the upper support roller aloft, overhead surpass 3 meters, do not have job platform on every side again, manually load and unload hanger and hang and receive steel rope and have very big potential safety hazard, belong to the dangerous operation project.
For fear of artificial high-altitude dangerous operation.The cold rolled continuous annealing unit machine configuration set that has the backing roll lifting device, this backing roll lifting device is provided with four each and every one suspension hooks, act on the side of backing roll 100 both sides bearing seats 101 respectively, correspondingly, two sides at bearing seat 101 are provided with lifting hole(eyelet), as depicted in figs. 1 and 2, Fig. 2 is the lateral plan of Fig. 1, lifting hole(eyelet) 102 is opened in two sides of two bearing seats 101, totally four, respectively corresponding four suspension hooks are driven opening of four suspension hooks of synchro control by chain-wheel mechanism and are closed by an electro-motor.During operation, integral body hangs in the driving, when four suspension hooks during to supporting roller bearing seat lifting hole(eyelet) 102 positions, four suspension hook synchronizing closes of motor driven, suspension hook extend in the lifting hole(eyelet) 102 of supporting roller bearing seat, thereby realizes the handling of backing roll, avoid manual work, also guaranteed the safety of roll change operation.But this lifting device complex structure is bulky, and the suspender equipment self-weight is big, the manufacturing expense height.
The utility model content
For addressing the above problem, the utility model provides a kind of planisher backing roll lifting device, promptly saves cost, handled easily, guarantees job safety again.
For achieving the above object, planisher backing roll lifting device of the present utility model, comprise frame body and four suspension hooks, described frame body has a hanger and four arms, described four suspension hooks are separately positioned on described four arms, and described suspension hook is connected with described arm by bearing pin, and described suspension hook can rotate around described bearing pin, described suspension hook below is provided with carries out spacing following stopper to described suspension hook, and described stopper is down captiveed joint with described arm.
The top of described suspension hook is provided with stopper, and the described stopper that goes up is captiveed joint with described arm.
Planisher backing roll lifting device of the present utility model is the Purely mechanical framed structure, and four suspension hooks import bearing seat from the backing roll top simultaneously, and extend into automatically in the lifting hole(eyelet) of supporting roller bearing seat.By planisher backing roll lifting device of the present utility model, the artificial dangerous operations such as hanger and steel rope of hanging have effectively been eliminated the potential safety hazard in the roll change operation when having avoided the backing roll roll change, have guaranteed the personal security of roll change operation.
Planisher backing roll lifting device of the present utility model, simple in structure, equipment self-weight is little, and manufacturing expense is low, and good economy performance can be applied to the roll change lifting operation of backing rolls such as cold rolling mill milling train, planisher.
