The technical scheme that the present invention takes for through-flow turbine runner blade lifting tool for the technical matters that exists in the solution known technology is: it includes hanger, also including endoporus, the screw thread cylindrical is arranged is the cylindrical-conical core that rises, endoporus the conical bore that cooperates with the described core that rises is arranged and cylindrical for the columniform ringfeder of runner bucket root step mounting hole aperture bearing fit, endoporus is threaded the rotation set with runner bucket root step mounting hole macropore bearing fit, the screwed hollow derrick of one end, the tubular locating bush, the threaded pull bar of baffle plate and two ends of centre hole is arranged, below described hanger, be fixed with a pipe; The described core retainer plate that rises is in described ringfeder, and the screwed end of described pull bar is meshed with the inner hole thread of the described core that rises; The screwed end of described suspension rod is meshed with the negative thread of described rotation set, and its other end is connected mutually with described baffle plate; The described hollow derrick that assembles is enclosed within the outside of described pull bar, and it is outer and mesh with a nut that the hole that the screwed other end of described pull bar passes described baffle plate leans out suspension rod; Be with described locating bush and hanger outside described suspension rod respectively, an end of described locating bush withstands on the described baffle plate, and the other end contacts with the pipe of hanger.
The present invention can also adopt following technical scheme:
Described core and the ringfeder of rising is for having the rise core and the ringfeder of hardness through heat treatment.
The cylindrical of described ringfeder has the opening of being opened to the other end respectively by two ends.
Described locating bush is one group of different sleeve pipe of length.
The technical scheme that the present invention takes about the using method of 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 the core that rises at the pull bar other end; The core outside puts ringfeder rising;
2) lifting device is sling in the aperture of ringfeder 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 ringfeder and blade tensioner;
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 ringfeder 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 ringfeder 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 rises is enclosed within the ringfeder 2, and the screwed end of 10 pull bars is meshed with the inner hole thread of the core 1 that rises; 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 opening of being opened to the other end respectively by two ends 11 is arranged on the periphery of ringfeder 2.
Locating bush 6 can be the different sleeve pipes of a group length according to the needs of different runner buckets.
Its principle is: ringfeder 2 is inserted in the runner bucket step mounting hole apertures, utilize nut 9 on the pull bar 10 to regulate to drive rise core 1 with ringfeder 2 and blade tensioner 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 ringfeder 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 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, at pull bar 10 other ends rise core 1 is installed; Ringfeder 2 on the core 1 outside rotation set that rises;
2) lifting device is sling in the aperture of ringfeder 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 tensioner between ringfeder 2 and the blade installation hole;
4) hanger 5 on the lifting blade is installed.
