Abstract
The utility model relates to water turbine turning wheel manufacture equipment, in particular to a three-point supporting welding device for a mixed-flow water turbine turning wheel. The three-point supporting welding device for the mixed-flow water turbine turning wheel is mainly used for solving the technical problems of poor quality, low efficiency and great operation difficulty when the turning wheel is welded in the prior art because the generator turning wheel adopts artificial welding technology, a component is directly put on the flat ground to be welded by at least two people during operation, but the turning wheel is made of metal and has the disadvantages of heavy weight and big size, and a big welding error can be generated only by artificial centralizing positioning and clamping. The three-point supporting welding device for the mixed-flow water turbine turning wheel, which is disclosed by the utility model, comprises a bottom plate (1) and is characterized in that the bottom plate (1) is fixedly provided with a middle shaft (3) by a fixed flange (2), three inner shores (5) which can be inserted into a turning wheel runner crown (4) are evenly distributed around the middle shaft, and outer shores (7) which can be inserted into a turning wheel runner band (6) are evenly distributed around the inner shores (5).
Description
Technical field
The utility model relates to a kind of rotary wheel of water turbine manufacturing equipment, especially relates to a kind of mixed-flow water turbine runner supported at three point welding equipment device.
Background technology
At present, existing hydroelectric generator is mainly that the drop by current generates electricity, and first wants ponding, by certain height, after formation hydraulic pressure, with the hydraulic turbine of generator, generate electricity, i.e. so-called drop hydroelectric generator, be mainly used in mountain region, hills, drop is larger, discharge is also larger.Chinese patent discloses a kind of hydroelectric generation unit (publication number: CN 101545444A), it comprises a fixed mount, at fixed mount, be provided with generator, below fixed mount, be provided with successively a plurality of current collectors, at each current collector port of export, be provided with the water wheels assembly that can rotate under natural flowing water drives, asking of water wheels assembly and generator, be provided with transmission mechanism, the water wheels assembly front end under fixed mount is provided with the adjustable adjusting device that enters the discharge size of water wheels assembly; Current collector is the housing of a cone-shaped, and its arrival end is greater than the port of export, before each adjusting device is located at respectively water wheels assembly; Adjusting device is included in a plurality of adjustment sheets that water wheels assembly space before arranges, and adjustment sheet is arranged on turning cylinder, is provided with pivoted arm on turning cylinder, and pivoted arm is regulated by pull bar, is provided with the power piston that can drive pull bar work on pull bar; Pull bar comprise be connected with power piston promote mainly pull bar and the attached pull bar being connected with pivoted arm, by triangle lever, connect promoting mainly between pull bar and attached pull bar.But the runner of this generator adopts pure artificial assembling and welding process, during operation, parts are directly placed on smooth ground and could complete together welding by least two people are above, but runner is made with metal, weight is large, volume is large, depend artificial righting location and clamping alone and can produce very large welding error, so there is shortcoming of poor quality, that efficiency is low, operation easier is large while welding runner.
Utility model content
The utility model is to provide a kind of mixed-flow water turbine runner supported at three point welding equipment device, it is mainly that the runner that solves the existing generator of prior art adopts pure artificial assembling and welding process, during operation, parts are directly placed on smooth ground and could complete together welding by least two people are above, but runner is made with metal, weight is large, volume is large, depend artificial righting location and clamping alone and can produce very large welding error, so the technical problem that welding exists during runner is of poor quality, efficiency is low, operation easier is large etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of mixed-flow water turbine runner supported at three point welding equipment device of the present utility model, comprise chassis, on described chassis, by mounting flange, be fixed with jackshaft, the surrounding of jackshaft is evenly equipped with three inner support posts that can insert runner crown, and the periphery of inner support post is evenly equipped with the outer support post that can insert runner lower ring.The location of runner crown and runner lower ring relies on three inner support posts and three outer support posts to realize, in welding equipment process, only crown need be placed to center chassis through inner support post, lower ring is positioned on outer support post, adjust with one heart and open height can be put into blade welding equipment, guarantee the concentricity of runner, avoided the drawback of artificial righting location.Runner error after welding equipment is reduced to 2mm by the 5mm of traditional approach.Adopt interchangeable diameter of axle technique, solved different inner diameters crown Placement Problems.
As preferably, described inner support post, outer support post are dislocatedly distributed ringwise at the middle part on chassis.The stationarity that has guaranteed runner welding, has improved Welding Safety.
As preferably, described outer support post is the adjustable outer support post of screw thread, has solved different runner opening problems.
Therefore, the location of the utility model crown and lower ring relies on three inner support posts and three outer support posts to realize, and has guaranteed the concentricity of runner, has avoided the drawback of artificial righting location, have rational in infrastructure, etc. feature.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is plan structure schematic diagrames of Fig. 1.
Parts, position and numbering in figure: chassis 1, mounting flange 2, jackshaft 3, runner crown 4, inner support post 5, runner lower ring 6, outer support post 7, runner bucket 8.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of mixed-flow water turbine runner supported at three point welding equipment device of this example, comprise chassis 1, on chassis, by mounting flange 2, be fixed with jackshaft 3, the surrounding of jackshaft is evenly equipped with three inner support posts 5 that can insert runner crown 4, and the periphery of inner support post is evenly equipped with the outer support post 7 that can insert runner lower ring 6.Inner support post, outer support post are dislocatedly distributed ringwise at the middle part on chassis.Outer support post is the adjustable outer support post of screw thread.
During use, runner crown 4 is placed to the jackshaft 3 at 1 centers, chassis through inner support post 5, runner lower ring 6 is positioned on outer support post 7, adjusts with one heart and open height can be put into runner bucket 8 welding equipments.
