Abstract

The utility model discloses a fan blade extracting device which comprises a pulling and extracting screw rod and a rectangular sizing block which is screwed on the pulling and extracting screw rod, wherein two clamping grooves are symmetrically formed in two sides of the rectangular sizing block, clamping hooks are arranged at the bottoms of two pulling rods which are arranged inside the clamping grooves in a movable mode, screw rod structures are arranged at the upper ends of the pulling rods, and fixing nuts are screwed on the screw rods. The fan blade extracting device has the advantages of being simple in structure, low in manufacturing cost, convenient to use and rapid in disassembly of fan blades. When the fan blade extracting device is used, the pulling and extracting screw rod is enabled to be abutted against a central shaft of a fan, the clamping hooks located at the bottoms of the two pulling rods are respectively clamped inside concave pits outside shaft sleeves of the fan blades, the position of the rectangular sizing block is well adjusted, the fixing nuts are screwed down, then a spanner is used for rotating the pulling and extracting screw rod, and the fan blades can be extracted from a main shaft.

Description

The impeller of blower extracting apparatus
Technical field
The utility model relates to the blower fan maintenance, impeller of blower extracting apparatus when especially relating to a kind of blower fan maintenance.
Background technology
Blower fan is manufacturer's equipment commonly used, breaks down in use and usually will carry out detachable maintaining.Because impeller of blower firmly is arranged on main shaft, dismantle very inconveniently, not only increased maintenance personal's labour intensity, also reduced maintenance efficiency.
Summary of the invention
The purpose of this utility model is to provide impeller of blower extracting apparatus a kind of simple in structure, firm, easy to use.
For achieving the above object, the utility model can be taked following technical proposals:
Impeller of blower extracting apparatus described in the utility model comprises drawing leading screw and the rectangle parallels that is screwed on described drawing leading screw, and the bilateral symmetry of described rectangle parallels offers draw-in groove; The two pull bars bottoms that activity is placed in described draw-in groove are provided with grab, and the upper end is screw-rod structure, has screwed hold-down nut on described screw rod.
The utility model has the advantage of simple in structure, cheap for manufacturing cost, easy to use, the dismounting impeller of blower very quick.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of Fig. 1.
The specific embodiment
As shown in Figure 1, 2, impeller of blower extracting apparatus described in the utility model comprises drawing leading screw 1 and the rectangle parallels 2 that is screwed on drawing leading screw 1, and the bilateral symmetry of rectangle parallels 2 offers draw-in groove 3; Two pull bar 4 bottoms that are placed in draw-in groove 3 are provided with grab 5, and the upper end is screw-rod structure, has screwed hold-down nut 6 on screw rod.During actual fabrication, pull bar 4 can be according to the many covers of model customization of blower fan, different blower fan for convenience detach.
During use, drawing leading screw 1 is held out against the blower fan axis, the bottom grab 5 of two pull bars 4 blocks respectively in the pit that is placed on outside the fan blade axle sleeve, adjust the position of rectangle parallels 2, tighten hold-down nut 6, then rotate drawing leading screw 1 with spanner, fan blade can be pulled out from main shaft.
