Abstract
The utility model relates to a tool for lifting runner blades of a tubular turbine, which comprises a conical expanding core, a cylindrical expanding sleeve, a rotating sleeve, a tubular hanger rod, a locating sleeve, a baffle and a pull rod; an inner hole of the expanding sleeve is matched with the expanding core; threads are formed at an inner hole of the rotating sleeve; threads are formed at one end of the hanger rod; a center hole is formed on the baffle; and threads are formed at two ends of the pull rod; a circular tube is arranged below a lifting lug; the expanding core is sleeved in the expanding sleeve; one threaded end of the pull rod is meshed with inner hole threads of the expanding core; the threaded end of the hanger rod is meshed with inner threads of the rotating sleeve; the other end of the hanger rod is fixedly connected with the baffle; the assembled hanger rod is sleeved outside the pull rod; the other threaded end of the pull rod passes through a baffle hole, stretches outside the hanger rod, and is meshed with a nut; the locating sleeve and the lifting lug are respectively sleeved outside the hanger rod; and one end of the locating sleeve is propped against the baffle, and the other end is connected with the circular tube of the lifting lug. The tool can lifting blades with different pore diameters through changing the expanding sleeve and the rotating sleeve; procedures such as lifting lug welding, lifting lug removal and relief grinding are saved, thereby saving costs; and disadvantages brought by welding lifting lugs of the blades are avoided, thereby improving the quality and the production efficiency.
Description
Technical field
The utility model belongs to a kind of tubular-turbine generator group assembly tool, particularly relates to a kind of through-flow turbine runner blade lifting tool.
Background technology
The installation of blade is generally adopted in the known cross-flow water turbine runner installation process is that center of gravity with blade finds and welds a hanger in this position and install.This kind installation method exists many drawbacks, as:
1. the general material of blade is 0Crl3Ni5Mo, and the hanger material is Q235A, and two welding are established and the wlding matching problem, even select stainless steel electrode for use, have the heat affected zone near the hanger, and there is variation in composition, and mechanical characteristics descends, the crackle that is easy to generate in service.
2. this smooth surface of vane type line processing back is attractive in appearance, and the hanger of installation weldering at last not only will weld and have thermal denaturation, also need remove relief grinding, the deface overall appearance.
3. waste lot of materials and handle man-hour.
Along with the raising that product design and producer require, these problems also are all producer's urgent problems.
Summary of the invention
The utility model saves the weldering hanger for the technical matters that exists in the solution known technology provides a kind of, removes the through-flow turbine runner blade lifting tool of operations such as hanger and relief grinding.
The technical scheme that the utility model is taked 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 utility model 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 advantage that the utlity model 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 utility model;
Fig. 2 be among Fig. 1 ringfeder analyse and observe enlarged diagram.
The specific embodiment
For further understanding summary of the invention of the present utility model, 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 pull bar 10 screwed ends are 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 and baffle plate 7 are fixedly connected; 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.
