Abstract
The utility model relates to a nuclear power plant overhauls and uses spanner, including spanner body and fastening lead screw, the relative both sides of spanner body be equipped with a fastening lead screw respectively. Compared with the prior art, the utility model has the advantages of processing is convenient, with low costs, efficient.
Description
Technical field
The utility model relates to the maintenance of a kind of nuclear power plant and uses aid, especially relates to the maintenance of a kind of nuclear power plant and uses spanner.
Background technology
In nuclear power plant's disintegration inspection operation, the spanner of use is generally hook-headed wrench at present, and this hook-headed wrench can not satisfy the maintenance needs, and the shortcoming of its existence has:
(1) needs the auxiliary spanner of controlling of manpower.
(2) spanner intensity can not satisfy the disintegration demand.
Summary of the invention
The purpose of the utility model is exactly to provide a kind of nuclear power plant's maintenance easy to process, that cost is low, efficient is high to use spanner for the defective that overcomes above-mentioned prior art existence.
The purpose of the utility model can realize through following technical scheme: spanner is used in the maintenance of a kind of nuclear power plant, it is characterized in that comprise wrench body and fastening screw mandrel, the relative both sides of described wrench body are respectively equipped with a fastening screw mandrel.
Described wrench body is provided with screw, and described fastening screw mandrel inserts in the screw.
Described wrench body is made up of the outwardly directed handle of annular spanner and annular spanner both sides.
Described fastening screw mandrel is provided with hold-down nut.
Compared with prior art, the utlity model has following advantage:
(1) easy to process, cost is low.
(2) save manpower, (process of knocking do not need manpower is auxiliary controls) guarantees personal safety
(3) firm and durable, reliable in quality.
Description of drawings
Fig. 1 is the structural representation of the utility model wrench body;
Fig. 2 is the structural representation of the fastening screw mandrel of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Spanner is used in the maintenance of a kind of nuclear power plant; Comprise wrench body 1 and fastening screw mandrel 3; Described wrench body 1 is made up of with the outwardly directed handle 12 in annular spanner 11 both sides annular spanner 11, and annular spanner 11 relative both sides are provided with screw 2 on the wrench body 1, and described fastening screw mandrel 3 inserts in the screw 2.The design of can controlling oneself as required of the thickness of wrench body, the part width is of a size of 50MM in this example, and fastening screw mandrel 3 is provided with the hold-down nut of M20.
During use, fastening screw mandrel 3 is inserted in the screw of spanner body 1, when guaranteeing that pump shaft is overhead above apart from 500mm, the wrench body cover is filled to axle sleeve adapter sleeve place, symmetrical fastening screw mandrel head knocks spanner handle to adapter sleeve and relaxes to the axle sleeve circular hole.
