Description
Technical field
The utility model relates to draught fan impeller, is specifically related to a kind of draught fan impeller tool special for dismounting.
Background technology
In maintenance of fan, the dismounting of draught fan impeller is an important service work.Because the structure of draught fan impeller and axle sleeve thereof is special, the withdrawal space of impeller is limited, adopts artificial unloading's method to knock impeller sleeve with iron staff or iron hammer from a side of impeller, both wastes time and energy, easily cause again the damage of draught fan impeller and main shaft, even cause scrapping of whole blower fan; And common hydraulic gripping device, mechanical gripper grapple are difficult to catch draught fan impeller, even if catch impeller edge, also may cause impeller distortion and fan vibration, dismounting difficulty is larger.The centrifugal blower particularly getting rusty for impeller sleeve and motor shaft junction, does not more have a set of effective extracting tool.
Utility model content
The utility model object is to overcome existing hand disassembly or handgrip dismantling technology, exist dismounting difficulty large, the problem that easily causes impeller and main shaft to damage, a kind of tool special for dismounting that utilizes reaction force principle dismounting draught fan impeller is provided, by two screw rod ends are screwed in two threaded connection holes on impeller, by the end alignment fan shaft of turret head screw bolt, by continuous screw-in turret head screw bolt, fan shaft is separated with impeller, realize the work of extracting of impeller, do not damage draught fan impeller and fan shaft.
The technical scheme that the utility model adopted is for achieving the above object: draught fan impeller tool special for dismounting, be provided with the T-shaped matrix of first plate body by strip and the perpendicular integrative-structure connecting and composing of columniform the second plate body, both ends along the first plate body length direction are provided with respectively gathering sill, in two gathering sills, be respectively equipped with one for connecting the screw rod of dust cap screwed hole on impeller, on screw rod, be provided with for being located at the nut on the first plate body, the second plate body is provided with the screwed hole that connects the first plate body and the second plate body along the position of its central axis, in this screwed hole, be equipped with for withstanding on the turret head screw bolt on blower fan impeller shaft.
Further, two gathering sills are equipped with opening in the end of the first plate body, and two gathering sills are with respect to the Central Symmetry setting of the first plate body.
Extracting tool of the present utility model, simple in structure, be easy to moulding and production in enormous quantities; For enterprise, a people can implement the dismantlement work of draught fan impeller, has improved overhaul efficiency.The T-shaped matrix of integrative-structure can avoid the long-term use of this instrument to cause the defect of two plate body mutual dislocation, separation.
Beneficial effect: 1, this extracting tool utilizes reaction force principle dismounting draught fan impeller, be about to screw in two dust cap threaded connection holes on impeller through two screw rod ends of two gathering sills, by the end alignment fan shaft of the turret head screw bolt in the screwed hole of screw-in the first plate body and the second plate body, by nut, two screw rods are positioned on the second plate body, by continuous screw-in turret head screw bolt, fan shaft is separated with impeller, realize the work of extracting of impeller, convenient and reliable, convenient operation, does not damage draught fan impeller and fan shaft.
2, can be according to the position of two threaded connection holes on impeller, adjust the position of two screw rods in gathering sill, this extracting tool can be applicable to dismantle the impeller of different sizes and model; And a people can implement the dismantlement work of impeller, has improved overhaul efficiency.
3, the screwed hole that the second plate body arranges along the position of its central axis, is confined in this screwed hole the screw-in path of turret head screw bolt all the time, can avoid turret head screw bolt constantly in screw-in process, to produce shift phenomenon.
