Description
Technical field
The utility model is related to impeller extracting apparatus technical fields, and in particular to a kind of replacer for fan impeller.
Background technology
It when safeguarding wind turbine, needs first to remove the impeller on blower fan main shaft, but since impeller is pacified with main shaft for a long time
It is fitted together, often forms adhesion, be not easy to remove, when encountering such case, the common method of people is with tools such as hammers
Impeller is beaten, the effect is unsatisfactory, and is easy to damage impeller.
The extracting tool for having following draught fan impeller is proposed in patent document CN205237953U, that is, includes I-shaped master
Body is located at the handle at the I-shaped main body both ends, a pair of of the pull rod lead screw being fixed in the I-shaped main body, a pair of pull rod silk
Bar is for being inserted into a pair of of removal hole of draught fan impeller and being fastened by locking nut.But there are following in above-mentioned conventional art
The angle of problem, i.e. pull rod lead screw is unadjustable, and pull rod lead screw needs the removal hole for being inserted into draught fan impeller, is only used for dismantling
Specific standard or the draught fan impeller for having removal hole.
Utility model content
Technical problem to be solved in the utility model be for the above-mentioned state of the art and provide it is a kind of it is simple in structure, make
With convenient and safe replacer for fan impeller.
Technical solution is used by the utility model solves above-mentioned technical problem：
A kind of replacer for fan impeller, including I-shaped main body and jack, the I-shaped main body include upper plate, lower plate
And the web between upper plate and lower plate, a pair of of sleeve is symmetrically installed between web, and L-type silk is installed in the sleeve
The lower end of bar, the lead screw is equipped with connecting screw by locking nut, and the lower end of the connecting screw is equipped with stress supporting plate,
The lower end of the stress supporting plate is equipped with claw, and the jack is mounted on lower plate medium position.
Further, the lead screw runs through sleeve, and is fixed by the fixing nut at sleeve both ends.
Further, the web both ends, which are symmetrically installed, is fixed with a pair of of handle.
The utility model has the beneficial effect that：The utility model is easy to operate, versatility is good, L-type lead screw, claw angle and
Size can be adjusted, and meet adjustment and the dismantlement work of the practical various serial impellers in scene；In the structure to influencing tensile strength
It is optimized, increased safety handle improves safety when operation, highly shortened the maintenance time of impeller.
