Abstract
The utility model discloses a kind of impeller spindle provision for disengagement, the upper end of described column connects into framework by drag link and longitudinal tie; Be provided with the first transverse slat between the column of framework side, be provided with the second transverse slat between the column of the opposite side relative with the first transverse slat, the second transverse slat is provided with " U " shape groove, and packing ring is equipped with in the inner side of " U " shape groove; Backing plate is equipped with in the centre of the first transverse slat, and the side of backing plate is equipped with jack and push pipe successively.The utility model does not need heating when dismantling impeller, utilizes hydraulic power that impeller is separated with main shaft, avoids oxygen rifle and toast the injury caused impeller.Fast impeller can be separated with main shaft, and to impeller and main shaft without any damage, structure is simple, with low cost, greatly reduces the labour intensity of air blast maintenance, is convenient to maintenance and changes.
Description
Technical field
The utility model relates to a kind of mechanical axis class extracting tool, specifically for the dismounting of impeller spindle in blower equipment maintenance, and particularly blower wheel disassembling device for main shaft.
Background technology
Generally use air blast when smelter transmission & distribution coal gas at present, in coal gas, the impurity such as dust or tar is when blower wheel High Rotation Speed, is easily irregularly attached on impeller, causes dynamic balancing to destroy, pressuring machine is broken down.Existing impeller is disassembled method from main shaft is when overhauling, and adopts around oxygen rifle two sides heating simultaneously impeller central hole, makes it expand, then to hit with a hammer push pipe from main shaft reverse side, makes main shaft from impeller " U " be separated shape groove and take out.But, because impeller is when heating, there will be the uneven or oxygen rifle malposition of heating, easily damaging impeller, and the push pipe of the main shaft one end that hits with a hammer, waste time and energy, thus cause impeller failure and operating efficiency not high.
Utility model content
Technical problem to be solved in the utility model is, provides a kind of provision for disengagement, by adopting hydraulic tool to be ejected from impeller by main shaft, avoiding oxygen rifle to toast shortcoming impeller being caused to damage, and improving the efficiency of dismantlement work.
The utility model for solving the problems of the technologies described above, by the following technical solutions.Impeller spindle provision for disengagement, comprises base and is arranged on the column on base, and the upper end of described column connects into framework by drag link and longitudinal tie; Be provided with the first transverse slat between the column of framework side, be provided with the second transverse slat between the column of the opposite side relative with the first transverse slat, the second transverse slat is provided with " U " shape groove, and packing ring is equipped with in the inner side of " U " shape groove; Backing plate is equipped with in the centre of the first transverse slat, and the side of backing plate is equipped with jack and push pipe successively.
Described base is provided with groove.
Described second transverse slat " U " shape slot puts and matches with the axle center of main shaft on impeller.
The utility model beneficial effect is, not needing heating, utilizing hydraulic power that impeller is separated with main shaft, avoiding oxygen rifle and toast the injury caused impeller when dismantling impeller.Fast impeller can be separated with main shaft, and to impeller and main shaft without any damage, structure is simple, with low cost, greatly reduces the labour intensity of air blast maintenance, is convenient to maintenance and changes.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, and see Fig. 1 to Fig. 3, impeller spindle provision for disengagement, comprises base 3 and be arranged on column 1 on the base 3, and the upper end of described column 1 connects into framework by drag link 13 and longitudinal tie 4; Be provided with the first transverse slat 10 between the column 1 of framework side, be provided with the second transverse slat 11, second transverse slat 11 between the column 1 of the opposite side relative with the first transverse slat 10 and be provided with " U " shape groove 12, packing ring 8 is equipped with in the inner side of " U " shape groove 12; Backing plate 2 is equipped with in the centre of the first transverse slat 10, and the side of backing plate 2 is equipped with jack 7 and push pipe 6 successively.Base 3 is provided with groove 14.On " U " shape groove 12 position of the second transverse slat 11 and impeller 5, the axle center of main shaft 9 matches.
embodiment:when the utility model uses, as shown in Figure 1, one end of column 1 is fixed on base 3, and the other end is connected with drag link 13 by longitudinal tie 4, forms frame structure.The impeller 5 with main shaft 9 is pulled down from air blast, and at one end of main shaft 9 suit upper gasket 8, device pedestal 3 is hung in bottle gouard moved by hands, impeller 5 being positioned over base 3 is provided with in groove 14, the endoporus of packing ring 8 is slightly larger than the external diameter of main shaft 9, packing ring 8 is placed on main shaft 9, and packing ring 8 is positioned between " U " shape groove 12 of the second transverse slat 11 and impeller 5.Backing plate 2 has been clamped inside first transverse slat 10 and between jack 7 base, the thickness of backing plate 2 is determined according to the length that jack 7 ejects and is regulated by changing, one end jacking block of jack 7 withstands push pipe 6 one end, push pipe 6 other end withstands the cap head of main shaft 9, by shaking the hydraulic system of jack 7, main shaft 9 is ejected from impeller 5.Use of the present utility model, making impeller 5 to be separated with main shaft 9 take-down time shortened to 30 minutes by original 6 hours, and maintainer tapers to two present people by original at least five people, substantially increases operating efficiency.
