Abstract
The utility model relates to dismounting tools of mechanical equipment, in particular to a dismounting mechanism of impellers of centrifugal draught fans, which comprises a lead screw nut, a lead screw, a handle, a support, a buckle and steel wires. The lead screw nut is arranged on the buckle, the lead screw and the lead screw nut are in thread match, the handle is arranged at the end of the lead screw, the end of the lead screw is connected with a support through an auxiliary rotation mechanism, the support is arranged on the buckle, and the steel wires are arranged on the buckle and used for connecting impellers of a draught fan. The dismounting mechanism of the draught fan impellers has the advantages of being convenient and fast in dismounting of the draught fan, improving working efficiency, protecting other parts of the draught fan, and reducing maintenance cost.
Description
Technical field
The utility model relates to a kind of dismounting utensil of machinery, specifically is a kind of draught fan impeller disassembly mechanism of centrifugal blower.
Background technique
Centrifugal fan is a kind of machinery commonly used, is widely used in the various factories, because the using scope of centrifugal fan is very wide; So in some special dimension, because Environmental Conditions is abominable, the impeller of centrifugal fan often damages or corrosion; In order to guarantee the normal operation of centrifugal fan; Just need change impeller, still, the mode of existing dismounting impeller one for beating impeller by hand; Inefficiency not only, but also easily other component of centrifugal fan are damaged.
Summary of the invention
The purpose of the utility model is to beat poor efficiency, the flimsy shortcoming that impeller is dismantled to the craft that exists in the above-mentioned technology; A kind of draught fan impeller disassembly mechanism of centrifugal blower is proposed; He dismantles the impeller adiabatic efficiency height, speed is fast, and can not cause damage to other parts of blower fan.
The technological scheme that realizes the utility model purpose is following:
The draught fan impeller disassembly mechanism; It comprises feed screw nut, leading screw, handle, support, buckle and steel wire, and feed screw nut is located on the buckle, leading screw and feed screw nut screw-thread fit; Handle is located at the leading screw end; The leading screw end is connected with support through an auxiliary rotating machinery, props up to be set up on the buckle, and steel wire is located at and is used to connect impeller of blower on the buckle.
Described auxiliary rotating machinery is a bearing, and bearing is fixed on the support bearing Neva and leading screw interference fit for outer watt.
The utility model has the advantages that the dismounting blower fan is convenient and swift, improved working efficiency, and protected the miscellaneous part of blower fan, reduced maintenance cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1, the draught fan impeller disassembly mechanism, it comprises feed screw nut 1, leading screw 2, handle 3, support 4, buckle 5 and steel wire 6; Feed screw nut 1 is located on the buckle 5; Leading screw 2 and feed screw nut 1 screw-thread fit, handle is located at the leading screw end, and the leading screw end is connected with support through an auxiliary rotating machinery 7; Be set up on the buckle, steel wire is located at and is used to connect impeller of blower on the buckle.
Described auxiliary rotating machinery is a bearing, and bearing is fixed on the support bearing Neva and leading screw interference fit for outer watt.
This mechanism is contained on the impeller retainer 8 of blower fan 9, steel wire 6 is entangled the fan blade impeller, during rotational lead screw, leading screw pull-up feed screw nut, feed screw nut pull-up buckle, leading screw, impeller has just left impeller retainer 8 this moment.
Claims (2)
