Abstract
The utility model discloses a kind of large-scale extracting tool to wheel, impeller, be intended to solve existing instrument and easily skid to when wheel, draught fan impeller at the motor that dismounting is large-scale, cause device damage and dismantle the large technical problem of difficulty.It comprises steel substrate, jack and two two ends with externally threaded screw mandrel, the fixing hole of through base plate is respectively equipped with in the bilateral symmetry position of base plate, the bottom of two screw mandrels is each passed through two fixing holes, be separately installed with nut at the external screw thread place of two screw mandrel bottoms, between nut and the lower surface of base plate, be provided with pad; Jack is arranged at the position on base plate in the middle of two screw mandrels.The utility model can realize the quick-detachment to wheel, impeller of large-size machine, blower fan, and structure is simple, convenient operation, and during use, one people can complete dismantlement work, time saving and energy saving, is conducive to improving large-size machine, the dismounting of blower fan and overhaul efficiency.
Description
Technical field
The utility model relates to large-size machine, maintenance of fan technical field, is specifically related to a kind of large-scale extracting tool to wheel, impeller.
Background technology
When carrying out motor, maintenance of fan, often need the impeller of wheel, blower fan is dismantled to motor, micro-machine, blower fan commonly use Three-claw pull-horse dismounting to wheel and impeller, and for large-scale motor concerning wheel, draught fan impeller, obvious defect is there is as extracting tool with existing Three-claw pull-horse, when dismantling, its three-jaw is difficult to hold to wheel, impeller, and easily skid, cause device damage, can not significantly adjustable range, dismounting difficulty is large, insufficient strength, has been difficult to the field-strip of large-size machine, blower fan.
Summary of the invention
The utility model is intended to solve existing instrument easily to be skidded to when wheel, draught fan impeller at the motor that dismounting is large-scale, causes device damage and dismantle the large technical problem of difficulty.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
Design a kind of large-scale extracting tool to wheel, impeller, comprise steel substrate, jack and two two ends with externally threaded screw mandrel, the fixing hole of through described base plate is respectively equipped with in the bilateral symmetry position of described base plate, the bottom of two screw mandrels is each passed through two fixing holes, be separately installed with nut at the external screw thread place of two screw mandrel bottoms, between described nut and the lower surface of described base plate, be provided with pad; Described jack is arranged at the position on described base plate in the middle of two screw mandrels.
Preferably, the upper surface of described base plate is provided with the caulking groove matched with described jack bottom shape, and the bottom of described jack is connected in described caulking groove.
Preferably, described jack is hydraulic jack.
Preferably, described pad is quality of rubber materials.
The beneficial effects of the utility model are:
Can realize the quick-detachment to wheel, impeller of large-size machine, blower fan, the dismounting difficulty overcoming the existence of existing detaching equipment is large, needs multi agent cooperation to carry out the problem of dismantlement work; Its structure is simple, convenient operation, and during use, one people can complete dismantlement work, time saving and energy saving, is conducive to improving large-size machine, the dismounting of blower fan and overhaul efficiency.

Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described, but the following example is only used to describe embodiment of the present utility model in detail, and limits scope of the present utility model never in any form.
Embodiment 1: a kind of large-scale extracting tool to wheel, impeller, see Fig. 1, Fig. 2, comprise the base plate 1 of steel, jack 2 and two two ends with externally threaded screw mandrel 3,4, the fixing hole 5 of through base plate 1 is respectively equipped with in the bilateral symmetry position of base plate 1, the bottom of two screw mandrels 3,4 is each passed through two fixing holes, be separately installed with nut 6 at the external screw thread place of two screw mandrel 3,4 bottoms, between nut 6 and the lower surface of base plate 1, be provided with rubber sheet gasket 7; Jack 2 is arranged at the position on base plate 1 in the middle of two screw mandrels 3,4, and the upper surface of base plate 1 is provided with the caulking groove 8 matched with jack 2 bottom shape, and the bottom of jack 2 is connected in caulking groove 8, and this jack 2 is hydraulic jack.
Device element involved in the embodiment above if no special instructions, is conventional equipment device.
The specific works mode of the large-scale extracting tool to wheel, impeller of the utility model is:
Use extracting tool of the present utility model dismounting large-size machine to wheel time, see Fig. 3, first the upper end of two screw mandrels 3,4 is passed wheel bore, and in screw mandrel 3,4 upper end, rubber sheet gasket and nut are installed successively, then jack 2 is placed on base plate, regulate its levelness and perpendicularity, slow compression jack 2, utilizes grilled gun to heat wheel, when reaching uniform temperature after jack 2 holds out against, gradually reduce jack 2, continues compression jack 2 and can extract wheel 9 when movable to wheel 9.
In conjunction with the accompanying drawings and embodiments embodiment of the present utility model is elaborated above, but the utility model is not limited to above-mentioned embodiment, in the ken that those of ordinary skill in the art possess, can also carry out changing or changing under the prerequisite not departing from the utility model aim.
