Further, the arc-shaped flange is arranged in the middle of the inner side of the semicircular annular hoop, and the wing plate is arranged in the middle of the outer side of the semicircular annular hoop.
Further, the wing plate is provided with an opening for a tension bolt to pass through.
Further, the radian of the arc-shaped flange is 90 degrees.
Further, the T-shaped supporting seat comprises a cylindrical tubular body, a seat plate is fixed at the upper end of the tubular body, and mounting holes for allowing tension bolts to penetrate through are formed in two side portions of the seat plate.
Furthermore, reinforcing rib plates are respectively fixed on the front side and the rear side of the seat plate.
Further, the tubular body and the seat plate are both made of steel.
Compared with the prior art, the utility model has the advantages of it is following: the special tool can effectively solve the problem that the impeller cannot be detached due to the fact that the mounting position of the shaft fan is limited when the shaft fan impeller is jammed.
The connecting bolt and the tension bolt used by the special tool are market universal bolts, and have wide purchasing approaches and low price. Impeller anchor clamps, T type supporting seat are 20# steel material, simple structure, utilize to overhaul the clout and can make, low cost while easy dismounting and firm reliable. Through field test, the impeller can be easily disassembled by using the special tool under the condition that the shaft and the fan impeller are rusted, the whole disassembling process generates pulling force by adjusting the stroke of the nut matched with the pulling bolt, the pulling force is uniform and controllable, the clamp and the impeller are well matched, the contact area is large, the stress is uniform, and the equipment is not easy to damage.

Detailed Description
In order to make the aforementioned features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below, but the present invention is not limited thereto.
Refer to fig. 1 to 4
The utility model provides a specialized tool for centrifugal axle adds fan impeller dismantlement, includes T type supporting seat 10 and is used for blocking the staple bolt formula impeller anchor clamps 20 of impeller, be provided with a pair of circular-arc flange 21 that is used for withholding the impeller recess in the hoop of staple bolt formula impeller anchor clamps, the both sides of staple bolt formula impeller anchor clamps all are provided with pterygoid lamina 22, the both sides portion of T type supporting seat all is provided with the lag bolt that is used for connecting the pterygoid lamina to through the nut stroke on the adjustment lag bolt, evenly afterburning, slowly pull out the impeller.
In this embodiment, the hoop-type impeller fixture includes two semicircular hoops 23, two ends of each semicircular hoop have mounting lugs 24 formed by bending outwards, and the mounting lugs are provided with through holes 25 for mounting connecting bolts. Therefore, the two semicircular annular hoops are connected together through the connecting bolts penetrating through the mounting lugs to clamp the impeller, and the inner diameter of the clamp formed by connecting the two semicircular annular hoops is larger than or equal to the outer diameter of the impeller.
In this embodiment, the arc-shaped flange is disposed at the middle of the inner side of the semicircular hoop, and the wing plate is disposed at the middle of the outer side of the semicircular hoop.
In this embodiment, the wing plate is provided with an opening 26 for passing a tension bolt, so that the tension bolt can pass through. The hole of the wing plate and the through hole of the hoop mounting lug are both in the center position.
In this embodiment, the arc of the arc-shaped flange is 90 ° so as to better fit with the impeller groove.
In this embodiment, the T-shaped support seat includes a cylindrical tubular body 11, a rectangular seat plate 12 is fixed to an upper end of the tubular body, and mounting holes 13 for passing tension bolts are provided on both sides of the seat plate, and correspond to the openings of the wing plates.
