Abstract
The utility model discloses a long screw fastening anti-loosening structure of a wind driven generator set, which comprises a hexagonal nut assembly, a locking nut and a plurality of washers, wherein the end part of the long screw penetrates through a structural member to be connected in the wind driven generator set, the hexagonal nut assembly and the locking nut are respectively sleeved and fastened at the end part of the long screw and are respectively positioned at two sides of the structural member, the hexagonal nut assembly comprises two rough tooth hexagonal nuts, and the washers are arranged between the two rough tooth hexagonal nuts, between the hexagonal nut assembly and the structural member and between the locking nut and the structural member. The utility model has the advantages of simple structure, convenient operation, good anti-loosening effect and the like.
Description
Technical Field
The utility model relates to the technical field of wind generating sets, in particular to a long screw fastening anti-loosening structure of a wind generating set.
Background
Long screws are sometimes used in cabins of wind turbine generators to connect 2 or more objects. Because the unit vibrates greatly in the operation process, if the long screw rod is fastened by adopting a common nut, the nut is easy to lose efficacy and loosen after long-time use, if the long screw rod is fastened by adopting a lock nut, the lock nut can only be screwed into the long screw rod by single clockwise rotation, and when the lock nut needs to be screwed into a long distance from the other end of the long screw rod, the screwing is very difficult.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provide a long screw fastening anti-loosening structure of a wind driven generator set, which has the advantages of simple structure, convenient operation, good anti-loosening effect and the like.
The aim of the utility model can be achieved by adopting the following technical scheme:
the utility model provides a long screw rod fastening locking structure of aerogenerator group, includes hexagon nut subassembly, lock nut and a plurality of packing ring, the tip of long screw rod passes the structure that waits to be connected in the aerogenerator group, hexagon nut subassembly and lock nut cup joint the tip of fastening at long screw rod respectively to be located the both sides of structure respectively, hexagon nut subassembly includes two thick tooth hexagon nuts, all is equipped with the packing ring between two thick tooth hexagon nuts, between hexagon nut subassembly and the structure and between lock nut and the structure.
Further, the washer between the two rough teeth hexagonal nuts is a lock washer.
Compared with the prior art, the utility model has the following advantages and beneficial effects:
the utility model has the advantages of simple structure, convenient operation, good anti-loosening effect and the like, can effectively avoid the problem of failure loosening under the vibration working condition of the unit, and can conveniently screw the nut no matter how long the thread section stroke of the long screw rod is.
Drawings
Fig. 1 is a schematic structural view of the anti-loosening structure of the present utility model.
Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments, and all other embodiments obtained by persons of ordinary skill in the art without making any inventive effort based on the embodiments of the present utility model are within the scope of protection of the present utility model.
As shown in fig. 1, this embodiment provides a wind turbine generator system long screw fastening locking structure, including hexagonal nut subassembly, lock nut 6 and a plurality of packing ring, the tip of long screw rod 7 passes the structure 8 that waits to be connected in the wind turbine generator system, hexagonal nut subassembly and lock nut 6 cup joint the fastening respectively in the tip of long screw rod 7 to be located the both sides of structure 8 respectively, hexagonal nut subassembly includes thick tooth hexagonal nut 1 and thick tooth hexagonal nut 3, is equipped with packing ring 2 between two thick tooth hexagonal nuts, is equipped with packing ring 4 between thick tooth hexagonal nut 3 and the structure 8, all is equipped with packing ring 5 between lock nut 6 and the structure 8.
Preferably, the washer 2 between the two rough hexagon nuts is a lock washer.
In practical application, assuming that one end of the structural member 8 to be connected is already fixed in the cabin, the long screw rod 7 needs to be fixed at the other end of the structural member 8, and the installation method of the anti-loosening structure specifically comprises the following steps:
1) The rough tooth hexagonal nut 1, the gasket 2, the rough tooth hexagonal nut 3 and the gasket 4 are sequentially penetrated into the long screw rod 7, the long screw rod 7 is penetrated from the lower part of the structural member 8, the gasket 5 and the locking nut 6 are sequentially screwed into the upper end of the long screw rod 7, fastening glue is dripped into the threads of the rough tooth hexagonal nut 1 and the rough tooth hexagonal nut 3, and then all nuts are pre-tightened.
2) The locking nut 6 at the upper end is clamped by an open spanner to prevent the locking nut from rotating, and the rough hexagon nut 3 at the lower end, which is close to the structural member 8, is fastened to a corresponding moment value by an open head and a moment spanner.
3) The locking nut 6 above is clamped by an open spanner, the rough tooth hexagonal nut 1 below the washer 2 is fastened to a corresponding moment value by an opening head and a moment spanner, and anti-loose marks are made.
The above description is only of the preferred embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto, and any person skilled in the art can substitute or change the technical solution and the inventive conception of the present utility model equally within the scope of the disclosure of the present utility model.
