Background technique
Gezhouba Hydropower Station unit replys bearing and bearing spider assembly is interference fit, and there are certain difficulty, dismantlings for dismantling
When generally arbitrarily look for two fulcrum supports to reply bearing bases, then beat at the top of bearing spider, separate bearing with support.This side
Method has the following deficiencies: in maintenance
(1) operation is highly inconvenient, influences upkeep operation efficiency；
(2) falsework built on the sand, is easily damaged associated components when beaing；
(3) bearing base stress surface is smaller, and repeatedly maintenance dismantling makes pedestal there is the risk ruptured.
Utility model content
The utility model aim is to provide a kind of dedicated Work tool of turbine-generator units reply bearing dismantling, this Work tool is adopted
With split type structure, a firm platform is provided to reply the dismantling of bearing, while dedicated Work tool supporting surface is made into conjunction
Big small circular stress surface shape is fitted, dismantling process bottom bracket bottom uniform force is made, dismantling process bottom bracket is avoided to occur
Damage phenomenon.
In order to realize above-mentioned technical characteristic, purpose of the utility model is realized as follows: a kind of turbine-generator units
It replys bearing and disassembles dedicated Work tool, it includes the support base being arranged symmetrically, and the bottom of the support base is provided with supporting leg,
The center of support base is machined with semicircular indentations, collectively forms the axle bed branch with centre bore after two neighboring support base combination
Support；The two sides of the axle bed support frame are connected with reaction frame structure and being integrally formed structure, the reaction frame structure and branch
Jack is inversely installed between support seat, the piston rod of the jack is coaxially arranged with the centre bore of axle bed support frame.
It is symmetrically fixed with connection otic placode on the side wall of the support base, leads between the connection otic placode on two neighboring support base
It crosses bolt to be connected, nut is installed on the bolt.
The reaction frame structure includes the bottom plate for being fixed on supporting leg two sides, and column, institute are fixed at the top of the bottom plate
It states and crossbeam is equipped with by limited block on column.
The diameter that the center-hole diameter of the axle bed support frame is greater than bearing is less than the outer diameter of bearing block.
The utility model has the advantages that:
1, dedicated Work tool is disassembled by using the bearing of above structure, can be used in the fast of turbine-generator units middle (center) bearing
Quick-detach, and during unpicking and washing, ensure that bearing block bottom uniform force, avoid traditional percussion dismantle in cause bearing block
Damaged defect, ensure that the safety of disassembly.
2, easily bearing block can be supported by using knockdown two support bases of dissection type, it is effective to increase
Big contact area between bearing block and support base, and then effectively prevent its and damaged danger occurs in disassembly process.
3, traditional percussion method for dismounting is substituted by using jack, reduces the labor intensity of operating personnel, is improved
Working efficiency.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the utility model overall structure main view.
Overall structure figure when Fig. 2 is the utility model not set jack.
Fig. 3 is two support base matching charts of the utility model.
Fig. 4 is structure chart of the utility model bearing support to be removed on two support bases.
In figure: supporting leg 1, support base 2, semicircular indentations 3, connection otic placode 4, bolt 5, nut 6, bottom plate 7, column 8, cross
Beam 9, limited block 10, jack 11, piston rod 12, bearing 13, bearing block 14.
Specific embodiment
The embodiments of the present invention is described further with reference to the accompanying drawing.
Fig. 1-4 is please referred to, a kind of dedicated Work tool of turbine-generator units reply bearing dismantling, it includes the branch being arranged symmetrically
Seat 2 is supportted, the bottom of the support base 2 is provided with supporting leg 1, semicircular indentations 3 are machined at the center of support base 2, adjacent two
The axle bed support frame with centre bore is collectively formed after a combination of support base 2；The two sides of the axle bed support frame and reaction frame
Structure is connected and being integrally formed structure, has been inversely installed jack 11 between the reaction frame structure and support base 2, and described thousand
The piston rod 12 on jin top 11 is coaxially arranged with the centre bore of axle bed support frame.It is dedicated by using the bearing dismantling of above structure
Work tool, can be used in the fast quick-detach of turbine-generator units middle (center) bearing, and during unpicking and washing, ensure that bearing block bottom by
Power is uniform, avoids the defect for causing bearing block breakage in traditional percussion disassembly, ensure that the safety of disassembly.
Further, connection otic placode 4, the company on two neighboring support base 2 are symmetrically fixed on the side wall of the support base 2
It is connected between ear connecting plate 4 by bolt 5, nut 6 is installed on the bolt 5.By using above-mentioned detachable connection side
Formula ensure that, can easily be cooperated with bearing block 13, and then support.
Further, the reaction frame structure includes the bottom plate 7 for being fixed on 1 two sides of supporting leg, and the top of the bottom plate 7 is solid
Surely there is column 8, pass through limited block 10 on the column 8 and crossbeam 9 is installed.Guarantee by using the reaction frame structure of above structure
It can be supported jack.
Further, the diameter that the center-hole diameter of the axle bed support frame is greater than bearing 13 is less than the outer of bearing block 14
Diameter.By using above structure Assurance of Size its can effectively be supported with bearing block 14 and bearing 13.
The course of work and working principle of the utility model:
Firstly, the support base 2 that two separate is sleeved on the outside of bearing to be removed, and bearing block 14 is supported on
On the centre bore for supportting seat 2；
Then, bolt 5 is passed through into the connection otic placode 4 on two support bases 2, and the two is fixedly linked using nut 6；
Finally, crossbeam 9 is fixed on column 8 by limited block 10, jack 11 is inversely installed in crossbeam 9 and bearing
Between 13, restart jack 11, bearing 13 is pressed by jack 11, and bearing block 14 is made in the limit of support base 2 at this time
It is moved down with lower stopping, and then makes bearing and bearing block carry out disassembly separation under pressure on top surface effect.
Above-described embodiment is used to illustrate the utility model, rather than limits the utility model, practical at this
In novel spirit and scope of protection of the claims, to any modifications and changes that the utility model is made, this reality is both fallen within
With novel protection scope.
