The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
A kind of draught fan impeller special dismounting frock, as shown in the figure, it comprises gets wheel frame 8, described one end of getting wheel frame 8 is fixedly connected with impeller hub, get in wheel frame 8 and be provided with straight-line feed driving mechanism, the direction of feed of described straight-line feed driving mechanism is parallel with impeller shaft 14, and the end of straight-line feed driving mechanism coordinates with impeller shaft 14, and the center of straight-line feed driving mechanism and impeller shaft 14 center are point-blank.
Wherein, get wheel frame 8 and comprise front end-plate 6 and the end plate 1 being parallel to each other, between described front end-plate 6 and end plate 1, symmetry is fixed with two gripper shoes 3, two gripper shoes 3 arrange near the limit portion of front end-plate 6 and end plate 1, and front end-plate 6, end plate 1 and two gripper shoes 3 adopt to be welded and fixed and link into an integrated entity and form one for the cavity of straight-line feed driving mechanism is installed.On front end-plate 6, be provided with the through hole corresponding with impeller shaft 14, the diameter of this through hole is greater than the diameter of impeller shaft 14, and both diameters poor be 2～4mm so that straight-line feed driving mechanism acts on impeller shaft.
The size of the size of front end-plate 6 and wheel hub end face is consistent, and the size of end plate 1 is laid jack and is as the criterion to facilitate.Described front end-plate 6 is fixedly connected with impeller hub, its fixed structure is: on front end-plate 6, be provided with two screwed hole II 7, these two screwed hole II 7 are corresponding with the dismounting hole site on impeller hub, and bolt 12, by two screwed hole II 7, is fixed on impeller hub getting wheel frame 8.Two gripper shoes 3 are arranged symmetrically with along the line of centres of two screwed hole II 7, two gripper shoes 3 are Special-shaped Plates, straight plate or arc, the lateral surface of two gripper shoes 3 is symmetrical arranged different bar 2, two indivedual bars 2 are welded and fixed with the outside of two Special-shaped Plates respectively, described other bar 2 arranges near end plate 1, not affect the operation of straight-line feed driving mechanism and other bar 2 easy to use, is as the criterion.
Wheel hub end face is vertical with wheel hub axis hole, be that wheel hub end face is vertical with impeller shaft 14, after getting wheel frame 8 being fixed on wheel hub, front end-plate 6 is vertical with end plate 1 with impeller shaft 14, and screwed hole II 7 and wheel hub dismounting hole on front end-plate 6 are consistent, wheel frame 8 and impeller shaft 14 axis have been guaranteed to get point-blank, exert all one's strength when being added in impeller shaft 14 and getting on wheel frame 8, point-blank stressed, stressed even, firm, can there is not the phenomenon of stressed inclination, use safety.
Above-mentioned straight-line feed driving mechanism is arranged in the cavity that front end-plate 6, end plate 1 and two gripper shoes 3 surround, and simultaneously according to the pore size of impeller hub and fit tolerance, straight-line feed driving mechanism can adopt three kinds of versions:
1. straight-line feed driving mechanism adopts leading screw, and the center of described end plate 6 is provided with the screwed hole I coordinating with leading screw, and the other end of described leading screw stretches in through hole.Leading screw is screwed in the screwed hole I of end plate, during rotating threaded shaft, for preventing that impeller and impeller shaft from rotating, with hand, catches other bar, and also available sleeve pipe is not on other bar, to guarantee to get carrying out smoothly of wheel.
2. straight-line feed driving mechanism adopts afterburning bolt 9, and this reinforcing bolt refers to the bolt that applies active force to getting wheel frame, and the center of described end plate 1 is provided with the screwed hole I 5 coordinating with afterburning bolt, and the other end of described afterburning bolt 9 stretches in through hole.Afterburning bolt 9 is screwed in the screwed hole I 5 of end plate, while rotating afterburning bolt 9, for preventing that impeller 13 and impeller shaft 14 from rotating, with hand, catches other bar 2, and also available sleeve pipe is not on other bar 2, to guarantee to get carrying out smoothly of wheel;
3. straight-line feed driving mechanism adopts jack 10, and the axis of jack 10 will be consistent with the axis of getting wheel frame 8, and the telescopic end of jack 10 is fixedly connected with push rod 11, and described push rod 11 stretches in through hole.Jack 10 is placed on gets the inner use of wheel frame 8, when if the impulse stroke of jack 10 is enough, can not adopt push rod 11, if when the impulse stroke of jack 10 is not enough, can between jack 10 and impeller shaft 14, add push rod 11, add the metal bar that a diameter is less than impeller shaft 14.
As shown in Figure 7, if gripper shoe 3 adopts Special-shaped Plates, guarantee the precision of Special-shaped Plates 3 length L, to guarantee the depth of parallelism of front end-plate 6 and end plate 1.As shown in Figure 3, guarantee that the size of L1 and L3 can be put into jack 10, the size of L2 be greater than draught fan impeller 13 in the axial direction wheel hub end face to the distance of impeller end face (non-impeller shaft side) so as operation.When straight-line feed driving mechanism adopts leading screw or afterburning bolt 9, gripper shoe 3 can adopt Special-shaped Plates, straight plate or arc, when straight-line feed driving mechanism adopts jack, in the time of can putting into jack 10 between the close two ends of front end-plate 6 in two gripper shoes 3, gripper shoe 3 can adopt Special-shaped Plates, straight plate or arc.
In the embodiment shown in fig. 9, getting wheel frame 8 is fastened on impeller hub 2 by two bolts 12, afterburning bolt 9 is screwed in to be got on wheel frame 8, pin after the other bar 2 of getting on wheel frame 8, rotate afterburning bolt 9, withstand on impeller shaft 14, continue the afterburning bolt 9 of rotation, along with stretching out of afterburning bolt 9, impeller 13 retreats and shifts out with getting wheel frame 8, until impeller 13 is thrown off with impeller shaft 14.
In the embodiment shown in fig. 10, getting wheel frame 8 is fastened on impeller hub by two bolts 12, jack 10 is placed on to be got in wheel frame 8, makes jack 10 and to get wheel frame 8 axis consistent, during the impulse stroke deficiency of jack 10, between jack 10 and impeller shaft 14, add push rod 11, jack 10 work, withstand on impeller shaft 141 by push rod 11, along with stretching out of jack 10, impeller 13 retreats and shifts out with getting wheel frame 8, until impeller 13 is thrown off with impeller shaft 14.
When straight-line feed driving mechanism adopts leading screw, rotating threaded shaft, leading screw is withstood on impeller shaft 14, impeller shaft 14 is motionless, the active force of leading screw is applied to be got on wheel frame 8, get wheel frame 8 by the bolt that is connected with impeller hub by force transmission to impeller 13, impeller 13 retreats with getting to take turns together with frame 8, until impeller 13 exits impeller shaft 14.
This disassembling fixture is applicable to impeller hub has the impeller 13 in dismounting hole to take out, the aperture that is particularly useful for various impeller hubs, and impeller hub coordinates draught fan impeller 13 dismountings of tension with impeller shaft 14, its installation and removal are simple, be convenient to dismantle impeller 13, time saving and energy saving, do not need to adjust, stress equalization, in draught fan impeller 13 unloading process, can not cause damage to fan part, be beneficial to maintenance blower fan, overcome in prior art in blower fan maintenance process, conventional impeller demolition method easily causes distortion to parts, damage and extracting tool are difficult for adjustment and cause the defects such as length maintenance time.
In the utility model, without the technical characterictic of describing, can pass through existing techniques in realizing, not repeat them here.The foregoing is only preferred embodiment of the present utility model; the utility model is not limited in the above-mentioned specific embodiment; the variation that those of ordinary skills make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
