Abstract
The utility model relates to a tool for positioning and mounting inner and outer cones of a through-flow turbine. The tool is characterized in that a bracket formed by longitudinal beams and crossbeams is included, wherein the longitudinal beams and the crossbeams adopt steel plate-welding structures; and an outer cone positioning and connecting plate is fixedly mounted at one end of the bracket, an inner cone positioning and connecting plate is fixedly mounted at the other end, and thread holes for positioning and mounting are formed at the lower parts of the outer cone positioning and connecting plate and the inner cone positioning and connecting plate. The utility model has advantages of reducing the whole weight by 50%, lowering the manufacturing cost, improving the inner and outer cone positioning precision of the through-flow turbine and meeting the requirements on the design dimensions of the channel.
Description
Technical field
The utility model belongs to hydraulic turbine manufacturing technology field, particularly relates to outer cone location and installation instrument in a kind of tubular turbine.
Background technology
Outer cone and inner cone are one of very important parts of tubular turbine, it must can be finished by the location and installation instrument in installation process at the scene, and all there is confidential relation the installation site of outer cone and inner cone with runner, so the position dimension required precision of outer cone and inner cone is very high in installation process.At present, outer cone location and installation instrument is the intermediate support that is welded by a steel plate and three vertical gussets in the tubular turbine relatively commonly used, the connecting plate that is packed in the intermediate support two ends respectively constitutes.The location and installation instrument of said structure is not only heavy, a large amount of steel of consumption, the cost height, and also the location and installation precision is difficult to reach designing requirement.Because this instrument overall weight is overweight, in the power station during on-the-spot the installation, very inconvenience, and then influenced the installation progress in whole power station.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of structure light, save material, reduce outer cone location and installation instrument in the high tubular turbine of manufacturing cost and location and installation precision.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Outer cone location and installation instrument in the tubular turbine, it is characterized in that: comprise the support that is made of longitudinal and cross beam, described longitudinal and cross beam is welded-steel plate construction; Be fixed with the outer cone plate that is located by connecting at support one end, the other end is fixed with the inner cone plate that is located by connecting, and described outer cone plate and the inner cone plate bottom that is located by connecting that is located by connecting all is shaped on the location and installation screwed hole.
The utility model can also adopt following technical scheme:
Described outer cone plate and the inner cone plate that is located by connecting that is located by connecting all is welded to connect with support.
Advantage and the good effect that the utlity model has are: because that the utility model adopts technique scheme, the integral body that can make tool to alleviate is nearly 50%, reduce manufacturing cost; Also can improve the interior outer cone positioning accuracy of the hydraulic turbine simultaneously, and guarantee the design size requirement of runner.In addition, the utility model also have simple in structure, be easy to make, advantage easy to install.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the C-C cutaway view of Fig. 1;
Fig. 3 is the utility model user mode schematic diagram.
Among the figure: 1, longeron; 2, crossbeam; 3, the outer cone plate that is located by connecting; 4, the inner cone plate that is located by connecting; 5, flange piece; 6, erecting tools; 7, hydraulic turbine outer cone; 8, bolt; 9, nut; 10, hydraulic turbine inner cone.
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:
See also Fig. 1-Fig. 3, outer cone location and installation instrument in the tubular turbine comprises the support that is made of longeron 1 and crossbeam 2, and described longitudinal and cross beam all adopts the steel plate welding to make, and so not only can alleviate the weight of instrument itself, and be easy to process, cost is low.Be welded with the outer cone plate 3 that is located by connecting at the support right-hand member, the support left end is welded with the inner cone plate 4 that is located by connecting, and described outer cone plate 3 and inner cone plate 4 bottoms that are located by connecting that are located by connecting all are shaped on the location and installation screwed hole.When installing at the scene, the outer cone of this location and installation instrument 6 plate 3 that is located by connecting is fastening with the screwed hole of hydraulic turbine outer cone 7 by bolt 8, nut 9, be located by connecting flange piece 5 screwed holes and hydraulic turbine inner cone 10 that plate 4 reserves on the fixed guide vane up and down by bolt and the hydraulic turbine of inner cone is fastening, can improve the interior outer cone positioning accuracy of the hydraulic turbine like this, and guarantee the design size requirement of runner.After interior outer cone is in place, again this instrument is removed.
