The present invention can also adopt following technical scheme:
Described bloated core and expansion set are for having the bloated core and the expansion set of hardness through heat treatment.
The cylindrical of described expansion set has the open slot of being opened to the other end respectively by the two ends of the tapered bore of expansion set.
Described locating bush is the different a plurality of sleeve pipes of a group length.
The technical scheme that the present invention takes about the using method of above-mentioned through-flow turbine runner blade lifting tool for the technical matters that exists in the solution known technology the steps include:
1) baffle plate is connected outside suspension rod, pack into locating bush and hanger with suspension rod by bolt earlier; Load onto rotation set at the threaded end of suspension rod; The pull bar that one end the is equipped with nut suspension rod of packing into is tightened bloated core at the pull bar other end; Put expansion set in bloated core outside;
2) lifting device is sling in the hole of the little end of expansion set insertion turbine blade step mounting hole, allowed rotation set hold out against the step end face of turbine blade step mounting hole;
3) after rotation set holds out against the step end face in blade installation hole, adjust the nut on the pull bar, make expansion set and blade swelling;
4) hanger on the lifting blade is installed.
The advantage that the present invention has with good effect is: this instrument can lift by crane different apertures blade by changing expansion set and rotation set, has certain commonality; Save the weldering hanger, go hanger, relief grinding operation, saved substantial contribution; The drawback of having avoided blade weldering hanger to bring has improved product design, and has improved production efficiency greatly.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 be among Fig. 1 expansion set analyse and observe enlarged diagram.
The specific embodiment
For further understanding content of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
As shown in Figure 1; The core 1 that expands is enclosed within the expansion set 2, and the screwed end of 10 pull bars is meshed with the inner hole thread of bloated core 1; Suspension rod 4 screwed ends are meshed with the negative thread of rotation set 3, and the other end of suspension rod 4 is connected mutually with baffle plate 7; The suspension rod 4 that assembles like this is enclosed within the outside of pull bar 10, the hole that the pull bar 10 screwed other ends pass baffle plate 7 lean out suspension rod 4 outer and with a nut 9 engagements; Be with locating bush 6 and hanger 5 outside suspension rod 4 respectively, an end of locating bush 6 withstands on the baffle plate 7, and the other end contacts with the pipe of hanger 5.
As shown in Figure 2, the open slot of being opened to the other end respectively by two ends 11 is arranged on the periphery of expansion set 2.
Locating bush 6 can be the different a plurality of sleeve pipes of a group length according to the needs of different runner buckets.
Its principle is: expansion set 2 is inserted in the runner bucket step mounting hole apertures, utilize nut 9 on the pull bar 10 to regulate to drive expand core 1 with expansion set 2 and blade swelling in runner bucket step mounting hole aperture, prevent fitting process suspension rod 4 landing from the blade; Rotation set 3 is tightened with suspension rod 4, and rotation set 3 is joined with blade step mounting hole macropore cunning, and hanger 5 can be adjusted the Heave Here by locating bush 6, and when the lifting hanger, rotation set 3, suspension rod 4 are sling blade together; Dismounting is during frock, and the nut 9 of reconciling on the pull bar 10 unclamps expansion set 2, outwards beats hanger 5 lifting device is taken out from blade.
The using method step of through-flow turbine runner blade lifting tool is:
1) earlier baffle plate 7 is coupled together by bolt 8 and suspension rod 4, put locating bush 6 and hanger 5 in the outside of suspension rod 4; Rotation set 3 on suspension rod 4 threaded end spinnings; The pull bar 10 that one end is equipped with nut 9 penetrates suspension rod 4, installs the core 1 that expands at pull bar 10 other ends; Expansion set 2 on bloated core 1 outside rotation set;
2) lifting device is sling in the aperture of expansion set 2 insertion turbine blade step mounting holes, allowed rotation set 3 hold out against and lean against on the step end face of turbine blade step mounting hole macropore;
3) after rotation set 3 holds out against the step end face in blade installation hole, adjust the nut 9 on the pull bar 10 again, make swelling between expansion set 2 and the blade installation hole;
4) hanger 5 on the lifting blade is installed.
