Description
Technical field
Back-up roll bearing counter-weight assist device is smoothed out with the fingers for straightener the utility model is related to one kind, belongs to plate-straightening machine and sets
Standby manufacture technology field.
Background technology
Medium-thick plate roller system of straightening machine needs offline strip inspection after line is using a full service life, according to service condition
It carries out replacing backing roll outside framework oil seal, replace, bearing cleaning, replace the maintenance activities such as backing roll.Since backing roll both ends carry
Bearing lacks the position of suitable suspended counterweight, so in back-up roll bearing operation is smoothed out with the fingers, usually hangs counterweight by steel wire rope
The method of extension is fixed on backing roll inner end and covers.Using this fixing means, dismounting operation is cumbersome, consumes a large amount of artificial works
When, and because counterweight fixation is insecure, be easy to cause backing roll spindle nose site tissue damage, influence to use.Thus, it is necessary to design system
Make a kind of counter-weight assist device and realize that straightener smoothes out with the fingers back-up roll bearing operation, consumption of reducing work hours avoids backing roll spindle nose position
Damage.
Utility model content
The technical problem to be solved by the utility model is to provide one kind back-up roll bearing counter-weight assist is smoothed out with the fingers for straightener
Device realizes safety, lossless operation.
Solving the technical solution of above-mentioned technical problem is：
One kind smoothes out with the fingers back-up roll bearing counter-weight assist device for straightener, including counter weight device, fixed outer guide collar, fixation
Screw rod, fixed outer guide collar, standing screw are located at counter weight device upper surface, and standing screw is located at the centre bit of fixed outer guide collar
It puts.
Straightener as described above smoothes out with the fingers back-up roll bearing counter-weight assist device, and counter weight device is equipped with guide collar in activity, living
Guide collar is overlapped with the center of fixed outer guide collar in dynamic, and guide collar is mounted in activity in guide collar in activity.
Straightener as described above smoothes out with the fingers back-up roll bearing counter-weight assist device, the internal diameter size and backing roll of fixed outer guide collar
The outer diameter of bearing matches.
Straightener as described above smoothes out with the fingers back-up roll bearing counter-weight assist device, the internal diameter size and backing roll of guide collar in activity
The outer diameter of spindle nose matches, and height matches with supporting the length of roller shaft head.
Straightener as described above smoothes out with the fingers back-up roll bearing counter-weight assist device, standing screw and the lifting of bearing roller shaft head end face
Hole matches.
Straightener as described above smoothes out with the fingers back-up roll bearing counter-weight assist device, and lifting nut is equipped on standing screw.
The beneficial effects of the utility model are：Counter weight device is fixed to a side axle of backing roll by way of spiral marking connection
On head, increase the dead weight of backing roll entirety, be conducive to backing roll and can smoothly be disengaged with bearing, ensure operation safety into
Row.In use, counter-weight assist device is fixed well with backing roll, is not collided mutually during disassembling, to supporting roll shaft
Head plays certain protective effect.Counter weight device is installed and disassembles easy, rapid, saves unnecessary labor hour and disappears
Consumption.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the side view of Fig. 1；
Fig. 3 is the usage state diagram of the utility model.
In figure：Counter weight device 1, fixed outer guide collar 2, standing screw 4, lift nut 5, backing roll at guide collar 3 in activity
6th, roller shaft head 7, hanging ring 8, cantilever crane 9, the interior guiding ring recess 10 of activity are supported.
Specific embodiment
With reference to shown in Fig. 1,2,3, guide collar 3 in the activity on counter weight device 1, the lifting nut on standing screw 4 are removed
5, backing roll 6 is sling using cantilever crane 9 and hanging ring 8, relies on the guiding role of fixed outer guide collar 2, bearing will be carried and supported
On standing screw 4 on one side end face precession counter weight device 1 of roller 6, counter weight device 1 and backing roll 6 are fixed.By support roller
It is sling together with counter weight device, top carries out smoothing out with the fingers bearing operation.Complete after backing roll upside bearing splits out, by backing roll 6 from
Refitting is put and is screwed out on the standing screw 4 on 1, is sling backing roll 6 using cantilever crane 9.
Guide collar in activity 3 is put into activity and is oriented in ring recess 10, slings 6 side of backing roll with bearing, according to
The guiding role of guide collar 3 in support activity will be screw into without the backing roll of bearing side on standing screw 4, will match refitting
1 is put to fix with backing roll 6.Entire external member is sling again, carries out smoothing out with the fingers bearing operation above.After bearing taking-up, then will
Backing roll is screwed out from counter weight device, completes operation.
