Description

Frock is dismantled to wind generating set main shaft

Technical Field

The utility model belongs to the technical field of wind power generation, and particularly relates to a tool for disassembling a main shaft of a wind generating set.

Background

At present, in the wind power generation field, in the work of dismantling the main shaft of a fan unit, the main shaft is pulled out after the expansion sleeve bolt is withdrawn, and when the unit operation time is long, the main shaft and the expansion sleeve of the main shaft are slightly meshed frequently in the field operation process, so that the main shaft is still difficult to take out after the main shaft expansion sleeve bolt is loosened, and the main shaft expansion sleeve is basically taken out in the field in a heating mode, but in the field operation process, the main shaft expansion sleeve workpiece is large in area and wide, the heating difficulty is large, the heating time is long, and the construction period is long.

Disclosure of Invention

The utility model aims to provide a tool for disassembling a main shaft of a wind generating set, which solves the technical problems of difficult disassembly and high working difficulty of the main shaft of the conventional fan set.

In order to solve the technical problems, the utility model adopts the following technical scheme: the utility model provides a frock is dismantled to wind generating set main shaft, includes interior sleeve pipe, outer tube and a plurality of locking pin, the external diameter of interior sleeve pipe equals the internal diameter of overcoat pipe, and the tip of interior sleeve pipe and an tip of outer tube all are fixed with the steel sheet, and interior sleeve pipe inserts and establishes in the outer tube, corresponds on the pipe wall of interior sleeve pipe and outer tube and has seted up a plurality of jacks, and all jacks set up along axial direction, the locking pin correspond respectively to insert and establish in the jack, the round hole has been seted up to the tip of locking pin.

Further, the inner sleeve and the outer sleeve are both of steel pipe structures.

Further, the length, thickness and outer diameter of the inner sleeve are 1500mm, 20mm and 120mm respectively, and the length, thickness and outer diameter of the outer sleeve are 1500mm, 15mm and 150mm respectively; the thickness and the diameter of the steel plate are 20mm and 200mm respectively, all jacks are arranged side by side at equal intervals, the distance between two adjacent jacks is 150mm, the diameter of each jack is 30mm, and the diameter of each locking pin is 28mm.

Compared with the prior art, the utility model has the beneficial effects that: the dismounting tool provided by the utility model adopts a combined sleeve structure, the assembly of the tool can be completed through the locking pin, and the tool can be adjusted and installed at will according to the working requirement.
