Abstract
The utility model relates to the safe overturn structure of a kind of large-scale water turbine runner, comprise stand, S. A., locating plate and crane, a stand is fixed with in the equal symmetry in large-scale water turbine runner both sides to be flipped, stand upper end level is hinged with a S. A., be fixed with a locating plate inside S. A., locating plate is fixedly connected with rotary wheel of water turbine; S. A. lateral offset.The utility model S. A. lateral offset, when runner 90-degree rotation, runner center of gravity is positioned at immediately below rotation axis, be in stable suspension state, do not need to carry out support top to runner, can come to a complete stop and carry out other operation, comparatively lower security degree is high for crane upset load, and hand of rotation is clear and definite, only adopts a crane to complete turning operation.
Description
Technical field
The utility model belongs to hydrogenerator and manufactures field, the safe overturn structure of especially a kind of large-scale water turbine runner.
Background technology
Large-scale water turbine manufacturing of runner, is subject to the restriction of traffic condition, in order to ensure the quality of runner, selects runner in building-site manufacture.The weight of general this runner is all more than 150t, and diameter is greater than 7m, and upset operation is very difficult, and if workpiece centre offset in switching process, even can cause danger.At present, the mode of protecting about adopting two wheel cranes during usual turning operation, together, one protects, and some also needs to adopt jack supplemental support location to prevent tipping, needs very large space, place, it is very large that execute-in-place coordinates difficulty, and field staff exists certain potential safety hazard.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of and rational in infrastructurely, convenient to install, cost is lower, the safe overturn structure of large-scale water turbine runner of highly versatile.
The utility model solves its technical matters and takes following technical scheme to realize:
The safe overturn structure of a kind of large-scale water turbine runner, it is characterized in that: comprise stand, S. A., locating plate and crane, a stand is fixed with in the equal symmetry in large-scale water turbine runner both sides to be flipped, stand upper end level is hinged with a S. A., be fixed with a locating plate inside S. A., locating plate is fixedly connected with rotary wheel of water turbine; S. A. lateral offset.
And the locating plate of both sides is all fixed on the central cross side of workpiece, and crane is articulated in workpiece opposite side top.
Advantage of the present utility model and good effect are:
The utility model S. A. lateral offset, when runner 90-degree rotation, runner center of gravity is positioned at immediately below rotation axis, be in stable suspension state, do not need to carry out support top to runner, can come to a complete stop and carry out other operation, comparatively lower security degree is high for crane upset load, and hand of rotation is clear and definite, only adopts a crane to complete turning operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is Fig. 1 right elevation (semi-sictional view);
Fig. 3 is switching process schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
The safe overturn structure of a kind of large-scale water turbine runner, comprise stand 4, S. A. 3, locating plate 2 and crane 5, a stand is fixed with in the equal symmetry in large-scale water turbine runner both sides to be flipped, stand upper end level is hinged with a S. A., be fixed with a locating plate inside S. A., locating plate is fixedly connected with rotary wheel of water turbine.
In order to effectively ensure that workpiece center-of-gravity position prevents revolution, S. A. lateral offset in this structure, the locating plate being specially both sides is all fixed on the central cross side of workpiece 1, and crane is articulated in workpiece opposite side top.
Be described see position shown in accompanying drawing 3, top on the left of workpiece linked up with by crane 5, and S. A. is arranged on position to the right in the middle part of workpiece.During work, crane loosens slow whereabouts, and workpiece is that axle center overturns with S. A., because center of gravity is positioned at the left side of S. A., center of gravity descent direction is identical with hand of rotation, overhead crane control reversal rate, safety is good, when being turned to 90 degree, lift hook position is taken off the workpiece lower end changing to other side, because workpiece center of gravity is below S. A., the position of workpiece deadweight holding workpiece, mustn't other supplemental support, crane is slowly sling from opposite side, until complete upset.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
