Description
Technical field
The utility model belongs to mechanical dismounting technical field, and in particular to it is a kind of for steam turbine from the support of integral blade
Top tool.
Background technique
For steam turbine in dress from integral blade, due to design, manufacture factor, or after service wear, leaf top
Often there is gap between shroud.The presence in such gap may impact Turbine Safety stable operation.For part
Gap beyond design standard need to be modified.To handle gap, support need to be carried out to blade, needed for reaching leaf top girth band
Gap, to form necessary operation processing space.
Summary of the invention
The utility model aim is to design one kind in view of the above shortcomings of the prior art to be used for steam turbine from integral blade
Support tool, to realize steam turbine leaf top girth band gap within the allowable range stepless changing the technical issues of.
The technical solution of the utility model is:
It is a kind of for steam turbine from the support tool of integral blade, comprising: jackscrew, nut, lower hook plate, lower hook plate branch
Seat, lower hook plate arc section A, lower hook plate arc section B, upper hook plate arc section and upper hook plate；The nut and upper hook plate are welded to connect,
Jackscrew penetrates nut rear support in the inner surface of lower hook plate arc section B；It welds the outer surface of lower hook plate support and lower hook plate arc section B
It connects in succession；The upper hook plate arc section of the upper hook plate is hooked in steam turbine blade position, the lower hook plate arc section A of the lower hook plate
Hang over leaf position under steam turbine.
The whole S-type structure of the lower hook plate；The lower hook plate arc section A size matches with blade under steam turbine；Institute
It states jackscrew outer wall and is provided with external screw thread, for being fastened with nut tightening.
The lower hook plate upper surface of support is equipped with semicircle groove, semicircle groove size and the outer surface lower hook plate arc section B ruler
It is very little to match.
The upper hook plate is integrally of an L-shaped structure, and upper hook plate arc section size matches with steam turbine blade size.
The utility model has the following beneficial effects:
The utility model design it is a kind of for steam turbine from the support tool of integral blade, leaf top girth band gap can be made
Stepless changing within the allowable range；Also the peripheral force of support blade can be changed into axial force by threaded relation, to adapt to tie up
Repair needs.

Specific embodiment
The a kind of of the utility model is described further for steam turbine from the support tool of integral blade below:
As shown in Figures 1 to 4, it is a kind of for steam turbine from the support tool of integral blade, comprising: jackscrew 1, nut 2, under
Hook plate 3, lower hook plate support 5, lower hook plate arc section A7, lower hook plate arc section B8, upper hook plate arc section 9 and upper hook plate 6；The spiral shell
Mother 2 is welded to connect with upper hook plate 6, and jackscrew 1 penetrates 2 rear support of nut in the inner surface of lower hook plate arc section B8；Lower hook plate support 5
It is welded to connect with the outer surface of lower hook plate arc section B8；The upper hook plate arc section 9 of the upper hook plate 6 is hooked in steam turbine blade position
It sets, the lower hook plate arc section A7 of the lower hook plate 3 hangs over leaf position under steam turbine.
The whole S-type structure of the lower hook plate 3；The lower hook plate arc section A7 size matches with blade under steam turbine；
1 outer wall of jackscrew is provided with external screw thread, for screwing fastening with nut 2.
Lower 5 upper surface of hook plate support is equipped with semicircle groove, semicircle groove size and the outer surface lower hook plate arc section B8
Size matches.
The upper hook plate 6 is whole to be of an L-shaped structure, and upper 9 size of hook plate arc section matches with steam turbine blade size.
The hook plate support 5 under the installation of lower 3 bottom of hook plate, to enhance lower 3 force part intensity of hook plate.In lower hook plate arc section
The outer surface A7 and upper 9 outer surface of hook plate arc section can remove partial arc section thickness according to actual needs, concede sky for jackscrew 1
Between.
A kind of support method of the support tool for steam turbine from integral blade as described above, including walk as follows
It is rapid:
Step 1: being hooked in steam turbine blade for upper hook plate 6, and lower hook plate 3 is hung over blade under steam turbine；Jackscrew 1 is worn
Nut 2 is crossed, and is supported to lower hook plate arc section B8 inner surface；
Step 2: after being completed, jackscrew 1 is rotated to direction is screwed, steam turbine will from the banding clearance of integral blade
It is stepped up；When banding clearance reaches desirable value, screw thread self-locking effect will guarantee that this gap value remains unchanged；It needs to remove
When, jackscrew 1 is rotated into i.e. dismountable device to direction is unscrewed.
The utility model is explained in detail above in conjunction with embodiment, but the utility model is not limited to above-mentioned implementation
Example, within the knowledge of a person skilled in the art, can also be in the premise for not departing from the utility model aims
It is lower that various changes can be made.The content being not described in detail in the utility model can use the prior art.
