Description
Technical field:
The present invention relates to a kind of small space oil cylinder quick replacement device and replacing options, belong to mechanical equipment technical field.
Background technique:
Modern steel rolling equipment is in Highgrade integration, and it is extremely compact to roll inboard installation arrangement.It is rolled with 6 roller of sour rolling mill, 5 rack tandem rolling
For machine, mill type UCM has middle roll shift, hydraulic bending roll, hydraulic working roll roller function.Due to equipment height
Integrated unique design is spent, is located in the smaller area that working roll opens shelves in mill housing and is disposed with for the positive and negative roller of working roll
Bending cylinder block, the emulsion spray beam for cooling work roller, latch and hydraulic, emulsion for working roll axial locking
The auxiliary devices such as pipeline.Moreover, this region also arranges intermediate roll shifting crossbeam and up and down for the curved of intermediate roll bending
Roller cylinder block and changing track for roll etc., overhaul of the equipments space is small, and equipment component replacement and maintenance amount is big and many and diverse, especially works
Roller changing track for roll lift cylinder, since it is installed on inside transition block, (transition block is for connecting working roll bending cylinder block and board
Mill), installation site is shown in Fig. 1, and replacement workload is very huge.
For the generally conventional replacing options of working roll lifting track oil cylinder:
It is mounted in transition block in view of working roll bending cylinder block, transition block is bolted on mill housing, and working roll
Lifting track oil cylinder is mounted in transition block, so, our conventional steps are as follows:
1, top working roll changing track for roll, working roll latch, emulsion spray beam, memorial archway liner plate, bending cylinder block, curved is removed first
Roller cylinder hydraulic pipeline, lift cylinder hydraulic pipeline；
2, transition block is then removed and with the handling out of mill housing window by transition block of the hanging devices such as chain block and driving
Out；
3, upper holder block is then removed；
4, lift cylinder is then removed；
5, transition block is hoisted in memorial archway window again after replacing new oil cylinder, returns dress installation transition block；
6, last gradually to restore the equipment of dismounting；
Entire operation process not only needs to remove numerous equipment, while because memorial archway window is smaller, upkeep operation is difficult, and transition block is difficult
The problems such as to lift, causes this cylinder replacing operation not only many and diverse, and the time is even more needs 24 hours or more, and every milling train has 4
Work roll changing lifting track oil cylinder, 5 milling trains add up to 20 oil cylinders, if conventionally replaced, workload pole
Its is huge.
In conclusion being directed to this status, our unit technical staff has carried out positive replacing options and has explored and improve, and adopts
Piston rod extracted out of cylinder barrel after only removing oil cylinder lower cover with motionless other equipment and is filled again after being sealed replacement again
Original 24 hours are down to 6 hours by the method for entering cylinder barrel, but still are not able to satisfy the actual demand at scene, and reason is very simple:
Firstly, equipment running status cannot be controlled, abnormal the case where cannot maintaining production tenesmus can only occur not in equipment
It obtains and has shut down replacement；
Secondly because repairing, oil cleanliness, which does not reach requirement, generates oil liquid loop fault；
In addition, the drawbacks of such replacing options is can only to replace piston rod and the sealing of rodless cavity rear end cap, there is bar as oil cylinder
Chamber end cap seal is still had no way of doing it；
More importantly the narrow place's operation of space for maintenance, upkeep operation personnel safety can not be effectively ensured.
Thus, there is an urgent need to one kind it is capable of the method and realization device of successful implementation fast online replacement, and expire with this
The maintenance requirements at foot scene.Task is very urgent, is also to have very big meaning in terms of cost efficiency for enterprise.It grinds
Study carefully out a kind of method of quick-replaceable small space oil cylinder and realization device with regard to very necessary.
