Description
Technical field
The utility model belongs to Nuclear Power Station grade pump maintenance engineering technical field, and in particular to a seed nucleus grade plunger pump part
Handling apparatus.
Background technology
Nuclear power station large size core grade plunger pump is sealed plunger by rubber seal element, for avoiding plunger cooling water
Or primary Ioops radiating medium leakage.Rubber seal element is vulnerable part, need to periodically be replaced, and replace seal assembly need by
Head partition is unloaded, since room space where pump group is narrow, in maintenance process, it is difficult to by the reliable handling in pump head part, and
There are certain security risks.
Invention content
The utility model aim is to propose a seed nucleus grade plunger pump part handling apparatus solve large-scale core grade plunger
The handling technical problem of pump part.
The technical solution of the utility model is：
One seed nucleus grade plunger pump part handling apparatus, including：Nut A, lifting lug, crossbeam, flat shim A, lifting beam, double end spiral shell
Bar, flat shim B and nut B, respectively there are one lifting beam, the beam surface upper centers for welding for the left and right ends lower part of the crossbeam
Lifting lug is installed, the left and right ends of the lifting beam are respectively arranged with double threaded screw.
Beam surface upper center as described above is equipped with tapped through hole, and the flat shim B is arranged on lifting lug and beam surface upper
Between, lifting lug is spirally connected across tapped through hole by nut B with crossbeam.
Lifting beam quantity as described above is two, the central part of each lifting beam and the lower part cross-wire weld at crossbeam both ends
It connects.
Lifting beam left and right ends upper surface as described above is symmetrically provided with tapped through hole, and the flat shim A is arranged on lifting beam
Between upper surface and double threaded screw.
Double threaded screw as described above is spirally connected fixation by nut A and lifting beam.
Flat shim A as described above and double threaded screw quantity are four.
The beneficial effects of the utility model are：
One seed nucleus grade plunger pump part handling apparatus of the utility model design is simple in structure, easy for installation；It and can
It leans on, handling smoothly is carried out to large-scale core grade plunger pump part, reduce the safety wind during core grade plunger pump part handling
Danger.

Specific embodiment
The utility model technology is further described below：
As shown in Fig. 1 to 5, a seed nucleus grade plunger pump part handling apparatus, including：Nut A1, lifting lug 2, crossbeam 3, plain cushion
Piece A4, lifting beam 5, double threaded screw 6, flat shim B7 and nut B8, respectively there are one carry for welding for the left and right ends lower part of the crossbeam 3
Beam 5 is risen, 3 upper face center of crossbeam is equipped with lifting lug 2, and the left and right ends of the lifting beam 5 are respectively arranged with double threaded screw
6。
3 upper face center of crossbeam is equipped with tapped through hole, and the flat shim B7 is arranged on 3 upper surface of lifting lug 2 and crossbeam
Between, lifting lug 2 is spirally connected across tapped through hole by nut B8 and crossbeam 3.
5 quantity of lifting beam is two, and the central part of each lifting beam 5 is welded with the lower part cross at 3 both ends of crossbeam.
The 5 left and right ends upper surface of lifting beam is symmetrically provided with tapped through hole, and the flat shim A4 is arranged in lifting beam 5
Between surface and double threaded screw 6.The double threaded screw 6 is spirally connected fixation by nut A1 and lifting beam 5.The flat shim A4 and double
6 quantity of head screw rod is four.
The specific installation steps of the utility model are as follows：
When preparing handling core grade plunger pump part, first by the threaded hole for being threaded into pump head 9 of double threaded screw 6 other one
It is interior；The suspension hook of chain block is hung to the lifting lug 2 on crossbeam 3 again；Chain block is slowly drawn high, realizes the slow steady of pump head 9
Handling.
The utility model is explained in detail above in conjunction with embodiment, but the utility model is not limited to above-mentioned implementation
Example, within the knowledge of a person skilled in the art, can also make under the premise of present inventive concept is not departed from
Go out various change.The prior art may be used in the content not being described in detail in the present invention.
