Specific embodiment
Structure depicted in Figure of description, ratio, size etc., only to cooperate the revealed content of specification, with
Understand for those skilled in the art and read, be not intended to limit the invention enforceable qualifications, therefore does not have technically
Essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size can be generated not influencing the present invention
Under effect and the purpose that can reach, it should all fall in the range of disclosed technology contents can cover.Meanwhile this
Cited such as "upper", "lower", "front", "rear", " centre " term in specification are merely convenient to being illustrated for narration, rather than
To limit the scope of the invention, relativeness is altered or modified, under the content of no substantial changes in technology, when also
It is considered as the enforceable scope of the present invention.
As shown in Fig. 2-Fig. 3, the present invention is a kind of steam turbine rotary spacing plate adjustment structure, and steam turbine includes cylinder 1, cylinder
Rotating barrier is equipped in 1, rotating barrier includes swivel becket 2, including at least one set of adjustment structure 3, and the adjustment structure 3 includes peace
Oil motor bracket 31 and the fixing sleeve 32 being mounted on inside cylinder 1, i.e. oil motor bracket 31 and fixing sleeve outside cylinder 1
32 position is fixed.Cross bar 33 is equipped in the oil motor bracket 31, one end of the cross bar 33 is for connecting
The connecting pin 331 of oil motor, the other end are the driving ends 332 for penetrating cylinder internal, and being equipped in the fixing sleeve 32 can be independent
The shaft 34 of rotation, the length direction of the axis direction of the shaft 34 perpendicular to cross bar 31, and the axis direction of shaft 34
Perpendicular to the plate face of swivel becket 2；The both ends of the shaft 34, which are respectively perpendicular, is connected with the first rocker arm 341 and the second rocker arm 342, described
First rocker arm 341 is hinged on one end of first connecting rod 35, and the other end of first connecting rod 35 is cut with scissors with 332 phase of driving end of cross bar 33
It connects, second rocker arm 342 is hinged on one end of second connecting rod 36, the edge phase of the other end and swivel becket 2 of second connecting rod 36
Hingedly.
In conjunction with Fig. 2 and Fig. 3, structural principle of the invention is: the oil motor with oil motor cooperation being only arranged outside cylinder 1
Bracket 31, other structures are arranged inside cylinder 1, effectively prevent mechanism it is external easily with cylinder external component (such as inblock cylinder
Steam ports etc.) interference the occurrence of.Specifically, oil motor passes through 31 lateral support of oil motor bracket outside cylinder, oil motor
It is cooperatively connected with the connecting pin 331 of cross bar 33, the cross bar 33 that sets gradually, first connecting rod 35, the first rocker arm 341, shaft 34, the
Two rocker arms 342, second connecting rod 36 constitute one group of completely lever regulated mechanism.When work, driven by the lateral straight line of oil motor
It is dynamic to transmit power, it is that first connecting rod 35 drives the first rocker arm 341 to swing, and then drive shaft 34 is in fixing sleeve 32 first
Power is transferred to the second rocker arm 342 by middle rotation, hereafter, the rotation of shaft 34, and the second rocker arm 342 drives second connecting rod 36 to swing,
Driving swivel becket 2 is realized eventually by the swing movement of second connecting rod 36 around the rotary motion of its center line, swivel becket 2 rotates
When can adjust bleeding point opening-closing size on rotating barrier, also just achieved the purpose that adjust rotating barrier, that is, realize adjust vapour
Turbine pumping.
As shown in figure 3, the oil motor bracket 31 be tubular structure, the cross bar 33 along oil motor bracket 31 middle line
Setting.
In order to reduce friction, bearing is equipped between the fixing sleeve 32 and shaft 34.
As shown in Fig. 2, in order to allow swivel becket 2 stress balance, adjustment structure 3 in rotation to have two groups, two groups of adjustings
Structure 3 is oppositely arranged on the two sides of swivel becket 2.Swivel becket 2 can be allowed to obtain one group of couple by two groups of structures and make tune
Section movement, completes regulatory function.In use, the synchronous horizontal driving of two sides oil motor is ultimately converted to the movement of swivel becket 2, it is complete
At function of the invention.
Between cross bar 33 in the present embodiment and first connecting rod 35, between first connecting rod 35 and the first rocker arm 341, second shake
Between arm 342 and second connecting rod 36, between second connecting rod 36 and swivel becket 2, realized by pin shaft hinged.
It is external that the oil motor branch connecting with oil motor is only set since structure of the invention is built in cylinder internal substantially
Frame is well suited for applying at the position of extraction opening two sides narrow space, such as extraction opening close to cylinder steam discharge position；In addition, this hair
The bright rotine position for being also applied for cylinder.
In conclusion a kind of steam turbine rotary spacing plate adjustment structure of the present invention, can be avoided and interfere with cylinder external component
The problem of.So the present invention overcomes some practical problems in the prior art effectively to have very high utility value and make
Use meaning.
The principle of the present invention and its effect is only illustrated in above embodiment, and is not intended to limit the present invention.This hair
It is bright to be improved under the premise of without prejudice to overall thought there are many more aspect, it all can be for those skilled in the art
Without prejudice under spirit and scope of the invention, can carry out modifications and changes to above-described embodiment.Therefore, technical field such as
Middle all equivalent modifications for being completed without departing from the spirit and technical ideas disclosed in the present invention of tool usually intellectual or
Change, should be covered by the claims of the present invention.
