Description
Technical field
It is especially a kind of to be filled for locking the locking of servomotor the present invention relates to the field of components of guide vane turbine-generator units
It puts.
Background technology
The locking device of guide vane servomotor is to stay in servomotor lock piston entirely in compressor emergency shutdown, guide vane closing
Off position is to ensure that one of technical measures of unit operation safety.With reference to shown in Fig. 6, conventional servomotor locking device is logical
Cross link block 16 and will lock hydraulic cylinder piston rod 14 and be fixed together with locking flashboard 11, processing get up it is more convenient,
But have the shortcomings that apparent, i.e., when installation, since the space of operation is smaller, hydraulic pressure will locked by link block 16
Cylinder piston rod 14 is very inconvenient when being connect with locking flashboard 11, while a large amount of manpower and materials are consumed, installation effectiveness
It is not high.
Invention content
In order to overcome in the prior art for being difficult to connect locking hydraulic cylinder piston rod and locking flashboard in smaller space
The problem of connecing provides a kind of for locking the locking device of servomotor, easy to operate, installation effectiveness height.
The technical solution adopted by the present invention to solve the technical problems is：A kind of locking device for being used to lock servomotor,
Including locking hydraulic cylinder, locking flashboard and guide pad, the locking hydraulic cylinder drive end bearing bracket is fixedly connected on servomotor cylinder and covers, institute
It states and T-slot is offered on locking flashboard, the locking hydraulic cylinder piston rod stretches out end and is provided with and the matched lock of T-slot
Head, the guide pad are fixedly connected on servomotor cylinder and cover, and the locking flashboard is slidably connected with guide pad.
In order to ensure that tapered end does not depart from T-slot, blind nut is further included, the blind nut is fixedly connected on servomotor cylinder and covers, spiral shell
Lid inserting end end face is connect with locking gate panel slide.
It is more firm during in order to lock servomotor, it is described to lock there are two flashboards and about servomotor piston rod radial symmetric
Distribution, the guide pad are symmetrical there are two and about lock flashboard center line.
The beneficial effects of the invention are as follows：It is provided by the invention a kind of for locking the locking device of servomotor, it realizes
In smaller operating space can also will locking hydraulic cylinder piston rod with lock flashboard link together, in use, only need to for
It installs in the smaller space of blind nut and tapered end is injected into T-slot, can realize the connection purpose of the two, device is easy to operate, significantly
Improve installation effectiveness.

Specific embodiment
Presently in connection with attached drawing, the present invention is described in detail.This figure is simplified schematic diagram, is only illustrated in a schematic way
The basic structure of the present invention, therefore it only shows composition related to the present invention.
As shown in Figs. 1-5, it is provided by the invention a kind of for locking the locking device of servomotor, including locking hydraulic cylinder,
Flashboard 11 and guide pad 12 are locked, the locking hydraulic cylinder drive end bearing bracket 13 is fixedly connected on servomotor cylinder cap 21, the locking
T-slot 11-1 is offered on flashboard 11, the locking hydraulic cylinder piston rod 14 stretching end is provided with to be matched with T-slot 11-1
Tapered end 14-1, the guide pad 12 is fixedly connected on servomotor cylinder cap 21, and the locking flashboard 11 is slided with guide pad 12
Connection.
As shown in Figure 1, in order to ensure that tapered end 14-1 does not depart from T-slot 11-1, blind nut 15 is further included, the blind nut 15 is fixed
It is connected on servomotor cylinder cap 21,15 inserting end end face of blind nut is slidably connected with locking flashboard 11.
As shown in Fig. 2, in order to lock servomotor when is more firm, the locking flashboard 11 is lived there are two and about servomotor
22 radial symmetric of stopper rod is distributed, and the guide pad 12 is symmetrical there are two and about lock 11 center line of flashboard.
During installation, for installing in the reserved space of blind nut 15,14 end of locking hydraulic cylinder piston rod will be arranged on
Tapered end 14-1 is injected in the T-slot 11-1 opened up on locking flashboard 11, and realizing will locking hydraulic cylinder piston rod 14 and locking flashboard
11 are connected, and guide pad 12 is that guiding role is played in the movement of locking flashboard 11, meanwhile, by installing blind nut 15, make blind nut 15
Inserting end end face is slidably connected with locking flashboard 11, prevents tapered end 14-1 from coming off from T-slot 11-1；During work, locking is started
Hydraulic cylinder, locking flashboard 11 is movable under the action of hydraulic cylinder piston rod 14 is locked, and is stuck in the card that servomotor piston rod 22 opens up
On slot end face, so as to which servomotor be locked, lock function is realized.
Provided by the present invention for locking the locking device of servomotor, realizing can will lock in smaller operating space
Hydraulic cylinder piston rod 14 is connected with locking flashboard 11, and device is easy to operate, substantially increases installation effectiveness.
Using above-mentioned desirable embodiment according to the present invention as enlightenment, by above-mentioned description, relevant staff
Various changes and amendments can be carried out in without departing from the scope of the present invention completely.The technical scope of this invention is not
