Description
Technical field
The invention belongs to nuclear power station service technique field, be specifically related to a kind of hydraulic power pump core-pulling device and the side of loosing core
Method.
Background technology
Two units of nuclear power station first stage of the project are respectively configured with the hydraulic power pump of a same model, just going up of this model pump
Side is designed with a hoisting beam, and when hydraulic power pump keep in repair, suspension chain block is carried out loosing core work.Due to chain block
Can be only formed a lifting point, be difficult to aligned with core bag center, during lifting, easily produce crank, core bag deflection etc. unfavorable because of
Element, causes the problem that pump housing endophragm is pulled by core bag big lid metal o-ring, later stage process more to bother.
Summary of the invention
It is an object of the invention to, not enough for prior art, it is provided that a kind of structure is simple with principle, it is possible to effectively solve
The unfavorable factor such as core bag crank, deflection when hanging, is prevented effectively from the pump housing and hydraulic power pump that other parts sustain damage
Core-pulling device and core pulling method.
The technical scheme is that
A kind of hydraulic power pump core-pulling device, including steel channel beam, screw rod, nut and plain presser, wherein said steel channel beam two
Respectively it is welded with a cylindrical support lower limb below Duan, between two cylindrical support lower limbs of described steel channel beam, is provided with two screws, two
Piece screw rod through through hole, the upper end of screw rod by nut screwing clamping on the upper surface of steel channel beam, described nut and steel channel beam trade mark
A plain presser it is provided with between face.
The upper and lower side of described screw rod is different screw threads, and threaded upper ends is the screw thread matched with nut, described lower end screw thread
For to wrap tegillum fine thread hole, portion screw thread suitable with hydraulic drive pump core.
A kind of hydraulic power pump core pulling method, looses core realization based on described hydraulic power pump, comprises the following steps:
Step one, pulls down mother nut and the kingbolt of big for fastening lid, then is hung out by big for hydraulic power pump lid；
Step 2, the nut of four fastening top tegillums of symmetrical dismounting and screw rod；
Step 3, is placed on individual steel channel beam in the upper plane of the pump housing, the cylindrical support lower limb bottom surface of steel channel beam and the pump housing
Upper plane is fitted, and the through hole of steel channel beam is positioned at directly over the screwed hole of dismantling screw；
Step 4, by four screw rods the most with one heart by four through holes of a pair steel channel beam, and by the fine thread of screw rod
All screw in the fine thread hole of top tegillum；
The invention has the beneficial effects as follows:
1, a kind of hydraulic power pump core-pulling device and the method structure of the present invention are simple with principle, easy to use；
2, a kind of hydraulic power pump core-pulling device and the method for the present invention can effectively solve the problem that the problem that bag of loosing core is difficult, and
And save time, laborsaving, work efficiency is high；
3, the pump housing and other parts will not be caused damage by a kind of hydraulic power pump core-pulling device and the method for the present invention.
