Description
Technical field
The utility model relates to a kind of holder devices of cold rolling quick-replaceable backing roll, belong to metallurgy industry cold rolling mill equipment
Technical field.
Background technique
Cold-rolling mill is frequently necessary to replacement support roller and working roll, work roll changing time are generally 10 minutes, and replaces branch
Support roller is generally 90 minutes.Main cause is: first is that the replacement support roller course of work is complicated；Second is that support roller is since weight is big,
Draw speed is slow.Currently, changing backing roll step are as follows:
1. working roll is released rack and is hung down；
2. extracting lower backing roll out, roll change frame is put on lower backing roll；
3. being inserted into lower backing roll, will be fallen under upper backup roll on roll change frame；
4. extracting lower backing roll out, upper and lower support roller is renewed；
5. being inserted into upper and lower new support roller；
6. upper new support roller is put into working position；
7. extracting lower backing roll out, roll change frame is hung away；
8. being put into lower support roll, it is packed into working roll.
When replacing support roller, support roller roll change buggy needs three into three to go out, and disengaging needs about 10 minutes every time, in addition hanging
The time is transported, causes to change the support roller time up to 90 minutes.
Utility model content
The utility model aim is to provide a kind of holder device of cold rolling quick-replaceable backing roll, can reduce backing roll
Roll changing time solves the problems, such as background technique.
The technical solution of the utility model is:
A kind of holder device of cold rolling quick-replaceable backing roll, comprising support frame, jack, connecting rod, pulley, roller spindle and
Handle, the lower section of support frame are equipped with a jack and two pulleys, and jack is located between two pulleys, one end point of connecting rod
It is not connect with jack and pulley, the other end of connecting rod is fixedly connected with roller spindle, and roller spindle is equipped with handle, the roller spindle
Positioned at the outside of support frame.
The jack and support frame support connect, and handle is drivingly connected by roller spindle and connecting rod and jack.
The top of support frame as described above is equipped with the supporting beam matched with cold rolling mill work roller.
Two pulleys below support frame as described above are separately fixed on support frame.
The distance between two pulleys below support frame as described above are with cold rolling mill work roller pulley spindle away from identical.
Using the utility model, when replacing support roller, working roll extraction is called away first, support frame is placed on working roll
On roll change buggy track, support frame is locked by roller spindle, support frame is advanced to milling train machine by mobile working roller roll change buggy
In frame, Working roll changing buggy is removed, manually rotated handle is fallen support frame by jack, will be propped up up and down using overhead traveling crane
Support roller is successively hung out.
The beneficial effects of the utility model are: compared with the background art, support roller roll change buggy goes out milling train machine by three into three
Frame is changed to one-in-and-one-out rack, reduces the roll changing time of backing roll, improves work efficiency, reduces production cost.
Detailed description of the invention
Fig. 1 is the utility model main view；
Fig. 2 is the utility model section view；
Fig. 3 is the utility model top view；
Fig. 4 is the utility model side view；
In figure: support frame 1, jack 2, connecting rod 3, pulley 4, roller spindle 5, handle 6, front support 7, supporting beam 8.
Specific embodiment
Below in conjunction with attached drawing, by example, the utility model is described in further detail.
Referring to attached drawing 1-4, a kind of holder device of cold rolling quick-replaceable backing roll includes support frame 1, jack 2, connecting rod
3, pulley 4, roller spindle 5 and handle 6, the lower section of support frame 1 are equipped with a jack 2 and two pulleys 4, and jack 2 is located at two
Between a pulley 4, one end of connecting rod 3 is connect with jack 2 and pulley 4 respectively, and the other end and roller spindle 5 of connecting rod 3 are fixed to be connected
It connects, roller spindle 5 is equipped with handle 6, and the roller spindle 5 is located at the outside of support frame 1.
In the present embodiment, jack 2 and the support of support frame 1 connect, and handle 6 passes through roller spindle 5 and connecting rod 3 and jack
2 are drivingly connected.Support frame 1 can be made to move up and down with respect to skidding 4 using jack 2, the distance between two pulleys 4 and cold rolling
Away from consistent, pulley 4 and cold rolling mill work roller pulley general can exchange machine working roll pulley spindle.Roller spindle 5 and working roll spindle
Unanimously, roller spindle 5 is located at the side of support frame 1.
The top of support frame 1 is equipped with front support 7 and supporting beam 8, and the effect of supporting beam 8 is support top working roll.
When milling train replaces support roller, working roll extraction is called away first, support frame 1 is placed on Working roll changing buggy rail
On road, before the front support 7 on support frame 4 is exposed to Working roll changing buggy.Mobile working roller roll change propulsion and locking device, lock
Tight roller spindle 5, support frame 1 is fixed, slow mobile working roller roll change buggy, and support frame 1 is advanced in rolling-mill housing.
After equal support frames 1 are pushed completely into rack, Working roll changing buggy is removed, manually rotated handle 6 will be propped up by jack 2
Support 1 is fallen, and contacts lower backing roll with changing rig, extracts upper lower backing roll out together, using overhead traveling crane by upper lower backing roll
It is replaced after successively hanging out；
New lower backing roll, upper backup roll and holder device are transported in rack using support roller roll change buggy, rotate hand
Handle 6 drives jack 2 to promote support frame 1, and pulley 4 is put on roll change buggy bracket by connecting rod 3, later using changing
Roller trolley removes holder device.Entire roll change process, it is only necessary to which roll change buggy one goes out into one, can complete to support
The replacement of roller.
