Description
Technical field
The invention belongs to mechanical engineering technical field, and in particular to a kind of backup roll of rolling mill bearing block embraces roller dismounting work
Tool.
Background technology
Backup roll of rolling mill filmatic bearing makes bearing produce the oil film axle in very high heat, bearing block due to contingency
Hold after tapered sleeve expanded by heating to roll side vibration, roll can be held after tapered sleeve cooling tightly, tapered sleeve limits bearing after holding roll tightly
Bushing and bearing block are outwards dismantled, and this bearing block for holding roll tightly often also can not be by it from roll with bearing block changer
Disassemble, typically often sling weight with crane in maintenance sites, the artificial weight that swings hits bearing block to roll outside, so
Although can dismantle the hanging piece of rammer in step, operating process will have the space of swing, but close to bearing block edge
Locate narrow, control rammer swinging track accurately hits rum point and is not easy to, and very heavy as the hanging piece of rammer,
It is therefore possible to hit damage bearing block, and security is also low.
The content of the invention
The present invention is in view of the above-mentioned problems, propose that bearing block embraces roller extracting tool, for improving filmatic bearing on-site maintenance behaviour
The security of work.
In order to realize the above-mentioned purpose of the present invention, the present invention proposes following technical scheme, including tup, fixed seat, is hinged
Seat, T-shaped lifting block, tie-beam and jump bit, it is characterised in that：It is connected at the top of the tie-beam with hinged seat, bottom is with consolidating
Reservation is connected, and the jump bit is fixed in fixed seat, and jump bit top land is contacted with tup.
As embodiment of the present invention, the tie-beam is symmetrical two arms shape structure, top and hinged seat pin
Axle is connected.
The riser of block is lifted in parallel slideway inside the hinged seat through T-shaped.
The supporting plate of the T-shaped lifting block is placed in two arm shape intersections of tie-beam.
The fixed seat includes the support base corresponding with jump bit end and the installing plate being connected with jump bit；It is described solid
Determine the end that hook is arranged at fixed seat；The guide key groove is placed in inside the open side edges in the middle of fixed seat.
The slide key coordinated with guide key groove is provided with the tup；The tup hook of the tup end stretches into roll neck
Sideshake.
The jump bit includes being provided with plunger in impact cylinder, impact cylinder.
Beneficial effects of the present invention：The present invention is carried by the jump bit being arranged between fixed seat and tup in hydraulic system
The impact kinetic energy produced under the power of confession, the stay hook and tup hook of stretching into roller neck sideshake are applied to opposite both direction
Plus impulsive force, the bearing block for holding roll tightly because of accident is disassembled from roll.Rolled because the present apparatus can accurately be placed on
Above roller, stay hook and tup hook accurately stretch into roller neck sideshake, will not because of the inaccurate impact of other hanging objects accident
Damage bearing block.

Embodiment
The present invention includes tup 1, fixed seat 5, hinged seat 6, T-shaped lifting block 7, tie-beam 8 and jump bit 9, its feature
It is：The top of tie-beam 8 is connected with hinged seat 6, and bottom is connected with fixed seat 5, and the jump bit 9 is fixed on fixed seat 5
On, the top land of jump bit 9 is contacted with tup 1.
The tie-beam 8 is symmetrical two arms shape structure, and top is connected with hinged seat 6 with bearing pin.
The riser 19 of block 7 is lifted in parallel slideway 18 inside the hinged seat 6 through T-shaped.
The supporting plate 17 of the T-shaped lifting block 7 is placed in 8 two arm shape intersections of tie-beam.
The fixed seat 5 includes the support base 12 corresponding with the end of jump bit 9 and the installing plate being connected with jump bit 9
10；The stay hook 3 is arranged at the end of fixed seat 5；The guide key groove 11 is placed in the open side edges in the middle of fixed seat 5
Portion.
The slide key 13 coordinated with guide key groove 11 is provided with the tup 1；The tup hook 2 of the end of tup 1 is stretched
Enter the sideshake of roll neck.
The jump bit 9 includes being provided with plunger in impact cylinder, impact cylinder.
When roll bearing seat 14 is embraced in dismounting, in the hole for hoist that lifting block 7 is penetrated with steel wire rope, hoist lifting hook will be lifted and kept off
Block 7 lifts, and the supporting plate 17 of lifting block 7 supports two arms of tie-beam 8, and provision for disengagement is hung to the top of roll 15,
As shown in fig. 6, the tup hook 2 of the stay hook 3 of the both sides fixed seat 5 of tie-beam 8 and the inner side of tup 1 is aligned into bearing block 14 and roll
Gap between 15 roll necks, falls suspension hook, and stay hook 3 and tup hook 2 are inwardly drawn in, extend into roller neck sideshake, will
Tie-beam 8 falls on the top of roll 15.Hydraulic pump 16 and jump bit 9 are connected with oil pipe.Start hydraulic pump 16, to rushing for jump bit 9
Input pulse hydraulic coupling in cylinder is hit, the plunger outward of impact cylinder is impacted, and fixed seat 5 and tup 1 are rushed by reverse pulse hydraulic
Hit after power and to be moved to outside opposite direction, the stay hook 3 and tup hook 2 of inner side are by bearing block 14 and roll 15 to opposite two
Direction impact shock, bearing block 14 and roll 15 bore the filmatic bearing for holding the conical surface of roll 15 tightly in the presence of impact kinetic energy
Set is separated from roll 15, and bearing block 14 is also disassembled from roll 15.
The oil film bearing conic sleeve in bearing block 14 seriously held tightly for special damage bearing, can adjust increase hydraulic pump
16 impact kinetic energy, the impulsive force of the stay hook 3 and the outside both sides of tup hook 2 of increase fixed seat 5 and the inner side of tup 1.
The present invention it is also possible to use compressed air pump and provide power for jump bit 9.
It is understood that above with respect to the specific descriptions of the present invention, being merely to illustrate the present invention and being not limited to this
Technical scheme described by inventive embodiments, it will be understood by those within the art that, still can be to present invention progress
Modification or equivalent substitution, to reach identical technique effect；As long as meet use needs, all protection scope of the present invention it
