To specifying position, see Fig. 5；
Installation frame roller 20 comprises the steps:
1) with reference to Fig. 6, first confirm that two described roll mill replacing being arranged in milling train on crossbeam 30 assist
The described jacking guiding mechanism 12 of frock 10 is in jacking state；
2) utilize driving 60 to be winched to by mill housing 50 by breast roll 20, and guarantee that breast roll 20 is brought to level,
See Fig. 6；
3) breast roll 20 is inserted milling train from milling train working side by driving 60；Breast roll 20 one end being introduced in milling train is first
Being positioned adjacent on the described roll mill replacing auxiliary mould 10 of milling train working side, final described breast roll 20 is put
Put on two described roll mill replacing auxiliary moulds 10；Note: breast roll 20 is inserted from milling train working side in driving 60
During entering milling train, described roll mill replacing auxiliary mould 10 is prevented from breast roll 20 run-off the straight when penetrating,
Substantially reduce and take 60 times of driving, see Fig. 7；
4) 60 suspension hooks of driving a vehicle are separated with breast roll 20；With reference to Fig. 2, start described jacking guiding mechanism 12, described jacking
Guiding mechanism 12 drives described Y type guide frame 11 to decline, and breast roll 20 declines, directly along with described Y type guide frame 11 simultaneously
Dropping to extreme lower position to described Y type guide frame 11, at this moment breast roll 20 two ends are respectively rested on memorial archway hole 501, see figure
8；
5) installation frame roller 20.
Preferably, with reference to Fig. 4 and Fig. 5, in the step 4 removing breast roll 20, first 60 suspension hooks of driving a vehicle are passed through steel wire
One end that rope is connected with chain block 40 with breast roll 20 is connected；Dismantle chain block 40 again, by chain block 40 and breast roll
20 other ends are connected, and are then connected with driving 60 suspension hooks by steel wire rope by chain block 40；Adjust chain block 40 so that machine
Frame roller 20 keeps level, finally utilizes driving 60 to winch to specify position by breast roll 20.
Preferably, with reference to Fig. 6, in the step 2 of installation frame roller 20, steel wire rope and driving are passed through in breast roll 20 one end
60 suspension hooks are connected, and its other end connects chain block 40, and chain block 40 is connected with 60 suspension hooks of driving a vehicle by steel wire rope；By adjusting
Whole chain block 40 so that breast roll 20 keeps level；Breast roll 20 is winched to by mill housing 50 by recycling driving 60,
Now chain block 40 is near milling train working side.
Preferably, with reference to Fig. 7, in the step 3 of installation frame roller 20, driving 60 from milling train working side by breast roll 20
Insert milling train；Breast roll 20 one end in milling train to be introduced into is firstly placed at the described rolling-mill housing near milling train working side
Roller is changed with time on auxiliary mould 10, removes chain block 40；Then driving 60 continuation hoisting frame roller 20；Final described frame
Roller 20 is placed on two described roll mill replacing auxiliary moulds 10.
Preferably, with reference to Fig. 2, described Y type guide frame 11 is made up of V-type frame and mobile jib 112, described mobile jib 112 upper end
It is located in described V-type frame bottom.Described V-type frame is completely formed by same round bar.Connection is had on final described mobile jib 112 upper end
Post, this connection column diameter is little with described mobile jib 112 diameter, and described connection post is located in described V-type frame bottom so that described mobile jib
112 fixing with described V-type frame are connected, the most not only ease of assembly, and easily process.
From the foregoing, it will be observed that when changing breast roll 20, by installing two described roll mills on crossbeam 30 in milling train
Change and use auxiliary mould 10, and jointly acted on by driving and chain block, it is possible to prevent breast roll 20 from extracting out and penetrating
Time run-off the straight；It addition, when extracting out and insert breast roll 20, owing to described roller 13 can be freely rotatable, at breast roll 20
With described roller 13 contact process, this roller 13 is beneficial to extract out and insert breast roll 20, thus improves breast roll 20 and change
Efficiency, shortens breast roll 20 replacing and takies 60 times of driving；And removing and installation frame roller 20 process, do not spend a large amount of
Time having bad luck at special hanger, improves dismounting and installation effectiveness.
Above-described embodiment only illustrative principle of the present utility model and effect thereof are new not for limiting this practicality
Type.Above-described embodiment all can be carried out by any person skilled in the art under spirit and the scope of the present utility model
Modify or change.Therefore, art has usually intellectual such as without departing from the essence disclosed in this utility model
