Description
Technical field
The utility model relates to equipment manufacturing field, is specifically related to a kind of large fan impeller hydraulic disassembling device.
Background technology
Impeller is the core component of blower fan work, impeller is by being arranged on blower fan main shaft with its fixing wheel hub, High Rotation Speed under the driving of motor, impeller hub and main shaft adopt interference fits or interference fit to connect, the cooperation of the large magnitude of interference that even adopts had connects, draught fan impeller is assembled on blower fan main shaft often through heating to wheel hub the mode making hole expand by manufactory, simultaneously, the shape position error that axle and hole are formed in process, surface accuracy error, and impeller and main shaft withstand long term exposure temperature during blower fan work, dust, the comprehensive function of moment of torsion etc., these factors make wheel hub and main shaft coordinate connect tightr, especially large fan impeller appearance and size and weight are all larger, disassembling section inconvenience, dismounting needs very large power could realize being separated of wheel hub and main shaft, jack can not meet the demands, the detachable maintaining work of fan impeller brings sizable difficulty, have a strong impact on maintenance progress, if it is improper to dismantle, will damage and even damage draught fan impeller and main shaft, cause larger economic loss.
Summary of the invention
The purpose of this utility model is to solve above-mentioned deficiency, provides a kind of large fan impeller hydraulic disassembling device that a kind of strength is large, load capacity is large, removal efficiency is high, safe and reliable, labour intensity degree is little.
For achieving the above object, the technical solution of the utility model is: a kind of large fan impeller hydraulic disassembling device, it is characterized in that: guide rail (6) is fixed on basis, guide rail (6) is upper while be provided with fixed mount (8), another side is provided with thrust frame (5), piston cylinder (1) is fixed on fixed mount (8), and piston rod (2) is installed in piston cylinder (1), and fixed mount (8) is provided with bracket (7); Thrust frame (5) is provided with U-shaped breach, and V-arrangement parallels (3) is placed in U-shaped breach, and the end face of U-shaped indentation, there is provided with gasket ring (4), and hydraulic pump (9) is connected with piston cylinder (1) by pipe-line system, and pipe-line system is provided with reversal valve (10).
Described bracket (7) slides vertically and adjusts installation site on fixed mount (8).
Described thrust frame (5) is the adjustment of horizontal slip vertically installation site on guide rail (6).
Described reversal valve (10) change hydraulic pump (9) in piston cylinder (1) supply the direction of pressure oil; Piston rod (2) by supply the direction of pressure oil to stretch along piston cylinder (1).
The beneficial effects of the utility model are: the utility model utilizes hydraulic means can produce very large thrust and dismantles impeller, the dismounting of large fan impeller is become simply, easily, maintenance personal's labour intensity can be reduced, improve maintenance work efficiency, and not fragile parts, avoid unnecessary economic loss.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment: see Fig. 1,2, a kind of large fan impeller hydraulic disassembling device, guide rail 6 is fixed on basis, while be provided with fixed mount 8 on guide rail 6, another side is provided with thrust frame 5, and piston cylinder 1 is fixed on fixed mount 8, piston rod 2 is installed in piston cylinder 1, and fixed mount 8 is provided with bracket 7; Thrust frame 5 is provided with U-shaped breach, and V-arrangement parallels 3 is placed in U-shaped breach, and the end face of U-shaped indentation, there is provided with gasket ring 4, and hydraulic pump 9 is connected with piston cylinder 1 by pipe-line system, and pipe-line system is provided with reversal valve 10.Hydraulic pump 9 operationally supplies pressure oil by pipe-line system in piston cylinder 1.
Described bracket 7 slides vertically and adjusts installation site on fixed mount 8.
Described thrust frame 5 is the adjustment of horizontal slip vertically installation site on guide rail 6.
Described reversal valve 10 change hydraulic pump 9 in piston cylinder 1 supply the direction of pressure oil; Piston rod 2 stretches along piston cylinder 1 by the direction of supplied pressure oil.
Its main method of operating is as follows: first, the Support Position of bracket 7 and V-arrangement parallels 3 pairs of main shafts is determined according to the length of main shaft, the position of impeller on main shaft, according to the size of two Support Positions place major axis diameter, the adjustment setting height(from bottom) of bracket 7, the height of V-arrangement parallels 3, the position of adjustment thrust frame 5 on guide rail 6 is also fixing; Secondly, choose suitable gasket ring 4 and be enclosed within main shaft, gasket ring 4 is positioned at the outer face of impeller hub, by impeller and wheel hub thereof with main shaft is positioned over bracket 7 and V-arrangement parallels 3 liang supports, spindle centerline and piston rod 2 center line is aligned; Again, primer fluid press pump 9 is to the side fuel feeding in piston cylinder 1, piston rod 2 stretches out promotion main shaft under the promotion of pressure oil, thrust frame 5 withstands gasket ring 4 makes impeller and wheel hub thereof keep motionless, thus make main shaft and impeller and wheel hub thereof produce relative motion, realize impeller and wheel hub is separated with the dismounting of main shaft; Finally, change fuel feeding direction by reversal valve 10 and piston rod 2 is retracted, so that lifting impeller, main shaft.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
