Abstract
The invention relates to a dismounting and mounting tool for a single-stage centrifugal fan high-speed rotor, and belongs to the technical field of machines. The dismounting and mounting tool comprises a fixed ring, a support, a connecting ring, adjusting bolts, a short welding plate, a vertical lifting arm, a horizontal lifting arm and a lifting ring. The fixed ring is arranged in the center of the support, and the connecting ring is arranged at the end of the support. The support and the vertical lifting arm are connected through the short welding plate, the vertical lifting arm and the horizontal lifting arm are vertically connected, and the lifting ring is arranged on the horizontal lifting arm. The dismounting and mounting tool is novel in design, simple, compact and reasonable in structure, low in manufacturing cost and suitable for being used for dismounting and mounting of all large single-stage high-speed centrifugal fan high-speed rotors.
Description
Technical field
The present invention relates to a kind of one-stage centrifugal blower fan high speed rotor dismounting frock, specifically a kind of can the special tooling of dismounting large-scale single-stage high-speed centrifugal blower high speed rotor, belong to field of mechanical technique.
Background technique
Existing single-stage high-speed centrifugal blower high speed rotor structure is less and high speed shaft can separate dismounting with impeller, but the design of the gear box structure of large fan is different, high speed rotor needs integral installation in gear-box, and high speed rotor weight, volume are larger, general diameter is at more than 600mm, weight is greater than 100kg, and when causing dismounting whole high speed rotor, focus point is difficult to find, and easily causes in disassembly process and damages high speed rotor.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of one-stage centrifugal blower fan high speed rotor dismounting frock is provided.
According to technological scheme provided by the invention, a kind of one-stage centrifugal blower fan high speed rotor dismounting frock, comprises retainer ring, support, fastener rings, adjustment bolt, short welded plate, vertical arm, horizontal hanging arm and suspension ring; Described support central authorities are provided with retainer ring, and bracket end is also provided with fastener rings; Be connected by short welded plate between described support with vertical arm, vertical arm is connected with horizontal hanging arm is vertical.
Described retainer ring and fastener rings are all welded on support; Short welded plate is welded on support equally.Described fastener rings is parallel with support.Described fastener rings is provided with 8 adjustment bolts.Adjustment nuts material on described adjustment bolt is engineering plastics.
Described horizontal hanging arm and being vertically all bolted between arm and short welded plate.Described horizontal hanging arm has a moving trough, moving trough is equipped with suspension ring.
Beneficial effect of the present invention: the present invention is novel in design, and structure is simple, compact, reasonable, low cost of manufacture, is applicable to all large-scale single-stage high-speed centrifugal blower high speed rotor dismounting and uses.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Description of reference numerals: 1, retainer ring; 2, support; 3, fastener rings; 4, bolt is adjusted; 5, short welded plate; 6, vertical arm; 7, horizontal hanging arm; 8, suspension ring; 9, moving trough; 10, impeller; 11, high speed shaft; 12, pull bar; 13, gear-box.
Embodiment
As shown in Figure 1: a kind of one-stage centrifugal blower fan high speed rotor dismounting frock, retainer ring 1, support 2, fastener rings 3, adjustment bolt 4, short welded plate 5, vertical arm 6, horizontal hanging arm 7, suspension ring 8 are comprised; Described support 2 central authorities are provided with retainer ring 1, and support 2 end is also provided with fastener rings 3; Be connected by short welded plate 5 between described support 2 with vertical arm 6, vertical arm 6 is connected with horizontal hanging arm 7 is vertical.
Described retainer ring 1 and fastener rings 3 are all welded on support 2; Short welded plate 5 is welded on support 2 equally.Described fastener rings 3 is parallel with support 2.Described fastener rings 3 is provided with several adjustment bolts 4; The quantity of adjustment bolt 4 is 8; Adjustment nuts material on described adjustment bolt 4 is engineering plastics.
Described horizontal hanging arm 7 and being vertically all bolted between arm 6 and short welded plate 5.Described horizontal hanging arm 7 has a moving trough 9, moving trough 9 is equipped with suspension ring 8.Described vertical arm and horizontal hanging arm are connected with bolt to be both convenient to dismantle, and also reduces space.
Be arranged on high speed shaft 11 by impeller 10 by bolt, high speed shaft 11 front end cylinder lever connecting rod 12, whole high speed rotor is installed in gear-box 13.
When the present invention uses; one-stage centrifugal blower fan high speed rotor dismounting frock is inserted on the pull bar 12 of high-speed rotor impeller 10 end; make the top adjusting bolt 4 near impeller 10 back through adjustment; now; because adjustment nuts adopts engineering plastics material; protect impeller 10, decomposed again the power concentrated on retainer ring 1 draw-in bar 12, thus reduce the distortion of pull bar 12.To be sling horizontal hanging arm 7 by suspension ring 8, then move suspension ring, just can find the center of gravity of high speed rotor accurately, thus successfully load in gear-box 13, turn avoid damaged in collision high speed rotor in disassembly process.
