Abstract
The utility model discloses a kind of dismountable axial-flow blower, comprise air duct, impeller and motor, described motor is connected with impeller by motor output shaft, described impeller is made up of blade, wheel hub and fixed plate, described wheel hub centre is provided with endoporus and by this endoporus and motor output shaft transition fit, described fixed plate is connected with wheel hub and motor output shaft respectively by fixing bolt.Adopt the blower fan with this impeller structures, draught fan impeller can be made in less space to complete dismantlement work, solve the problem of subway station machine room fan impeller demolition difficulty.
Description
Technical field
The utility model relates to a kind of blower fan, specifically a kind of dismountable axial-flow blower.
Background technique
Subway station wind machine room is cost-saving when building, general floor space is very little, the layout of internal unit closely, the space of installing and removing draught fan impeller when safeguarding blower fan is very little, if adopt conventional method to draw horse to be just difficult to field-strip as extracting tool by three melons, therefore need to design a kind of novel blower fan and solve the problem that cannot complete dismantlement work in little space.
Model utility content
For solving the problems of the technologies described above, the utility model provides a kind of dismountable axial-flow blower, solves the problem of subway station machine room fan impeller demolition difficulty, draught fan impeller can be made in less space to complete dismantlement work.
The technical solution adopted in the utility model is:
A kind of dismountable axial-flow blower, comprise air duct, impeller and motor, described motor is connected with impeller by motor output shaft, it is characterized in that, described impeller is made up of blade, wheel hub and fixed plate, and described wheel hub centre is provided with endoporus and by this endoporus and motor output shaft transition fit, described fixed plate is connected with wheel hub and motor output shaft respectively by fixing bolt.
The tapped hole that diameter is greater than fixing bolt is provided with in the middle of described fixed plate.
The utility model has the advantages that: adopt the blower fan with this impeller structures, draught fan impeller can be made in less space to complete dismantlement work, solve the problem of subway station machine room fan impeller demolition difficulty.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model impeller demolition process schematic;
Fig. 3 is that the utility model impeller demolition completes schematic diagram;
1. air ducts, 2. blade, 3. wheel hub, 4. motor, 5. motor output shaft, 6. fixed plate in figure, 7. M16 bolt, 8. M20 bolt, 9. pad.
Embodiment
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is further described, but protection domain of the present utility model is not limited thereto.
As shown in Figure 1, a kind of dismountable axial-flow blower, comprise air duct 1, impeller and motor 4, described motor 4 is connected with impeller by motor output shaft 5, and described impeller is made up of blade 2, wheel hub 3 and fixed plate 6, and described wheel hub 3 centre is provided with endoporus and by this endoporus and motor output shaft 5 transition fit, described fixed plate 6 is fixedly connected with wheel hub 3 by 3 M16 bolts 7, is fixedly connected with motor output shaft 5 by 1 M16 bolt 7.
Being provided with the tapped hole of a M20 in the middle of described fixed plate 6, using during for dismantling blower fan.
Detaching fan process of the present utility model is as follows: first unclamp 4 M16 fixing bolts 7 on fixed plate 6; pull down fixed plate 6; then in the middle of the end of motor output shaft 5, the protection of 9, pad and buffer function is put; load onto fixed plate 6; tighten 3 the M16 bolts 7 be connected with wheel hub 3 outside fixed plate 6; the tapped hole aimed at again in the middle of fixed plate 6 is screwed into 1 M20 bolt 8, as shown in Figure 2.Then continue to tighten with spanner, and M20 bolt 8 is progressively screwed into by reinforcing inwards, whole impeller ined succession by such fixed plate 6 will outwards movement, until impeller unloads impeller after shifting out motor output shaft 5, as shown in Figure 3.
Impeller in the application's scheme, fixed by M16 bolt and fixed plate, then the bolt coordinated with M20 tapped hole in the middle of fixed plate is screwed into, bolt end head acts on pad and forms point of action, fastening force between bolt and screw thread is greater than the active force between wheelboss inner hole and motor output shaft, thus is shifted out by impeller.This structural design can make draught fan impeller complete dismantlement work in less space, solves the problem of subway station machine room fan impeller demolition difficulty.
Above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit, and to not departing from any amendment of the utility model spirit and scope or equivalent replacement, it all should be encompassed in the middle of right of the present utility model.
