Background technique
In large-scale power station steam feed pump machine, Ji Feng cooling chamber is externally connected with the end cap of feed pump, sets in cooling chamber
There is rotation axis, when overhauling to feed pump, since cooling chamber is placed in pump body, operating space is narrow when disassembly,
Cause disassembly difficult.Currently, often first end cap is split out by cooling chamber's card slot, then uses when being dismantled to cooling chamber
The interim tool of L shape is fixed in cooling chamber's card slot, by by manpower pulling or in a manner of jack lifting by cooling chamber to
Outer pull-out.It is not only time-consuming and laborious using this disassembly mode, it is inconvenient, and when pulling out cooling chamber be easy because
Unbalance stress, and the accurate machined surface of cooling chamber and the pump housing or rotation axis is damaged, cause unnecessary economic loss.
Utility model content
Existing in the prior art above insufficient to solve, the utility model is intended to provide a kind of large-scale power station steam-operating water supply
Pump machine seal cooling chamber's extracting tool, to achieve the purpose that be readily disassembled, it is easy to operate, shorten the construction period.
To achieve the above object, technical solution used by the utility model is as follows: a kind of large-scale power station steam feed pump
Ji Feng cooling chamber extracting tool, including at least two screw rods, one end of the screw rod pass through blind plate and limit blind plate by nut
Position on screw rod withstands on blind plate on rotation axis end face；The other end of screw rod, which is fixed on, can be connected in cooling chamber's card slot
In interior shackle member, shackle member is made of at least two fan circumferential clasps.
As the improvement of the utility model, there is gap between the snap ring, so that shackle member is the annulus with gap
Shape.
Another kind as the utility model improves, and the screw rod is circumferentially evenly distributed on snap ring around rotation axis axle center,
Snap ring is circumferentially evenly distributed in card slot around rotation axis axle center.
The third as the utility model improves, and at interval of 90 ° of settings, one screw rod on the blind plate, shackle member is by two
A fan circumferential clasp forms, and symmetrical two screw rods of symmetrical center line about shackle member are fixedly connected on each snap ring.
As the further improvement of the utility model, be provided on the blind plate be in contact with rotation axis end face it is very heavy
Top.
Due to the adoption of the above technical solution, compared with prior art, acquired beneficial effect is the utility model:
Shackle member is connected in cooling chamber's card slot by the utility model, while blind plate being withstood on rotation axis end face, is turned
Dynamic nut applies the pulling force pulled out to shackle member using rotation axis as fulcrum, so that shackle member be made to drive cooling chamber outside
It pulls out；When using extracting tool in background technique, it usually needs time half a day could complete to dismantle, and the utility model only needs
Want a hour can be by cooling chamber by splitting out in steam feed pump, hence it is evident that improve work efficiency；
The shackle member of the utility model is made of at least two fan circumferential clasps, multiple snap rings is arranged in this way, so that snap ring
It fits easily into cooling chamber's card slot, guarantees that snap ring is more securely stuck in cooling chamber's card slot；
The shackle member of the utility model is the circular ring shape with gap, annulus shape and the cooling chamber's card slot of shackle member
Annulus shape is identical, has biggish contact area with card slot when being connected in card slot conducive to shackle member, applies in this way to shackle member
During pulling force, shackle member can be more securely connected in cooling chamber's card slot, so that cooling chamber is easy to be pulled outwardly
Out；
The screw rod, snap ring of the utility model are circumferentially uniformly distributed rotating around rotation axis axle center, it is ensured that each screw rod institute
The pulling force being subject to is identical, so that pulling force suffered by each snap ring is identical, so that cooling chamber is avoided by uniform pulling force
The accurate machined surface of injuring part due to unbalance stress reduces generated economic loss；
The utility model can be arranged very heavy when the frictional force of cooling chamber and the feed pump pump housing is larger on blind plate
Top, withstands rotation axis by jack, applies pulling force in shackle member from screw rod；
The utility model be readily able to disassembly, it is easy to operate and quick, can shorten the construction period, improve working efficiency, reduction
Need to put into is artificial, mechanical.
The utility model is suitable in large-scale power station steam feed pump Ji Feng cooling chamber, is used for cooling chamber by the pump housing
On split out.
