The utility model discloses a tup, base, articulated seat, promotion dog, tie -beam and jump bit, its characterized in that: the tie -beam top is connected with articulated seat, and the bottom is connected with the base, the jump bit is fixed on the base, jump bit top land and tup contact.
Description
Technical field
This utility model belongs to mechanical engineering technical field, is specifically related to a kind of backup roll of rolling mill bearing block and embraces roller extracting tool.
Background technology
Backup roll of rolling mill filmatic bearing makes bearing produce the highest heat due to contingency, to roll side vibration after oil film bearing conic sleeve expanded by heating in bearing block, roll can be held tightly after tapered sleeve cooling, tapered sleeve limits bearing insert after holding roll tightly and bearing block is outwards dismantled, it often also cannot be disassembled from roll by this bearing block holding roll tightly with bearing block changer, typically commonly use crane in maintenance sites to sling weight, artificial swing weight impact groove bearing outside roll, although step so can be dismantled, but the space of the hanging piece of rammer swing to be had in operating process, but near bearing block edge narrow, control rammer swinging track accurately hits rum point and is not easy to, and hanging piece as rammer is the heaviest, bearing block is damaged it is therefore possible to clash into, and safety is the lowest.
Summary of the invention
This utility model, for the problems referred to above, proposes bearing block and embraces roller extracting tool, for improving the safety of filmatic bearing on-site maintenance operation.
In order to realize above-mentioned purpose of the present utility model, the utility model proposes following technical scheme, including tup, base, hinged seat, lifting block, tie-beam and jump bit, it is characterized in that: described tie-beam top is connected with hinged seat, bottom is connected with base, described jump bit is fixed on base, and jump bit top land contacts with tup.
As embodiment of the present utility model, described tie-beam is two symmetrical arm shape structures, and top is connected with hinged seat bearing pin.
Promote the riser of block through T-shaped in parallel slideway within described hinged seat.
Described T-shaped promotes the gripper shoe of block and is placed in two arm shape crossings of tie-beam.
Described base includes the support seat corresponding with jump bit end and the installing plate being connected with jump bit；Described fixation hook is arranged at the end of base；Described guide key groove is placed in inside the open side edges in the middle of base.
The slide key coordinated with guide key groove it is provided with on described tup；Described tup end is provided with the tup hook stretching into roll neck sideshake；Described tup end is provided with boss.
Described jump bit includes impacting cylinder, is provided with plunger composition in impact cylinder.
The beneficial effects of the utility model: the impact kinetic energy that this utility model is produced under the power that hydraulic system provides by the jump bit being arranged between base and tup, the fixation hook and tup hook that stretch into roller neck sideshake are applied impulsive force to contrary both direction, the bearing block holding roll because of accident tightly is disassembled from roll.Owing to this device can accurately be placed on above roll, fixation hook and tup hook stretch into roller neck sideshake accurately, will not hang the inaccurate impact of thing and accidental injury bearing block because of other.

Detailed description of the invention
This utility model includes tup 1, base 5, hinged seat 6, promotes block 7, tie-beam 8 and jump bit 9, it is characterized in that: described tie-beam 8 top is connected with hinged seat 6, bottom is connected with base 5, and described jump bit 9 is fixed on base 5, and jump bit 9 top land contacts with tup 1.
Described tie-beam 8 is two symmetrical arm shape structures, and top is connected with bearing pin with hinged seat 6.
Promote the riser 19 of block 7 through T-shaped in parallel slideway 18 within described hinged seat 6.
Described T-shaped promotes the gripper shoe 17 of block 7 and is placed in 8 two arm shape crossings of tie-beam.
Described base 5 includes the support seat 12 corresponding with jump bit 9 end and the installing plate 10 being connected with jump bit 9；Described fixation hook 3 is arranged at the end of base 5；Described guide key groove 11 is placed in inside the open side edges in the middle of base 5.
The slide key 13 coordinated with guide key groove 11 it is provided with on described tup 1；Described tup 1 end is provided with the tup hook 2 stretching into roll neck sideshake；Described tup 1 end is provided with boss 20.
Described jump bit 9 includes impacting cylinder, is provided with plunger composition in impact cylinder.
When roll bearing seat 14 is embraced in dismounting, penetrate in the hole for hoist promoting block 7 with steel wire rope, lifting block 7 is mentioned by hoist lifting hook, two arms of tie-beam 8 are supported by the gripper shoe 17 promoting block 7, provision for disengagement is hung to above roll 15, as shown in Figure 6, tup hook 2 inside the fixation hook 3 of 8 liang of wing bases 5 of tie-beam and tup 1 is aligned the gap between bearing block 14 and roll 15 roll neck, fall suspension hook, by fixation hook 3 and tup hook 2 inward collapsible, it extend in roller neck sideshake, tie-beam 8 is fallen roll 15 top.Hydraulic pump 16 and jump bit 9 is connected with oil pipe.Start hydraulic pump 16, input pulse hydraulic coupling in the impact cylinder of jump bit 9, the plunger outward impact of impact cylinder, base 5 and tup 1 are moved to outside rightabout by after reverse pulse hydraulic impulsive force, the fixation hook 3 of inner side and tup hook 2 by bearing block 14 and roll 15 to contrary both direction impact shock, bearing block 14 and roll 15 are under the effect of impact kinetic energy, being separated from roll 15 by the oil film bearing conic sleeve holding roll 15 conical surface tightly, bearing block 14 is also disassembled on roll 15.
For the oil film bearing conic sleeve in the bearing block 14 that special damage bearing is seriously held tightly, the impact kinetic energy increasing hydraulic pump 16 can be regulated, increase the fixation hook 3 inside base 5 and tup 1 and the impulsive force of the outside both sides of tup hook 2.
This utility model it be also possible to use compressed air pump and provides power for jump bit 9.
It is understandable that, above with respect to specific descriptions of the present utility model, it is merely to illustrate this utility model and is not limited to the technical scheme described by this utility model embodiment, it will be understood by those within the art that, still this utility model can be modified or equivalent, to reach identical technique effect；Needs are used, all within protection domain of the present utility model as long as meeting.
