Abstract
The invention relates to a servomotor locking device comprising a U-shaped fork, a hydraulic cylinder and a base. The extending end of the piston rod of the hydraulic cylinder is fixedly connected to the U-shaped fork; the top of the hydraulic cylinder is provided with a first cylinder cover, the bottom of the hydraulic cylinder is provided with a second cylinder cover, a clamping groove is formed on the outer wall of the first cylinder cover circumferentially, and two locking blocks are arranged between the first cylinder cover and the U-shaped fork; a round projection is formed on the inner wall of one end of one locking blocks and is fixed with the clamping groove in a matching manner, and the other ends of the locking blocks are pressed against the U-shaped fork. According to the device, one ends of the locking blocks are connected to the clamping groove of the first cylinder cover, the other ends resist and isolate the U-shaped fork, and a function of limiting piston rod retraction is realized; the locking blocks are fixedly connected through screws, so that assembling and disassembling are facilitated, and the problems of large sizes of the cylinder covers and the U-shaped fork due to the application of a screw connecting manner are solved; in addition, security of upstream unit maintenance is improved greatly.
Description
Technical field
The present invention relates to servomotor of guide vane, relate to specifically a kind of servomotor locking device.
Background technique
Existing for water guide mechanism servo for hydroturbine, comprise gray iron, piston rod, piston.But existing servomotor of guide vane mechanical locking, adopts screw rod to connect U-shaped jaw and front end housing.But from installing space angle, consider, many times need front end housing to have enough positions that screw flight hole is installed, the size of front end housing and U-shaped jaw is all larger like this.
Summary of the invention
The technical problem to be solved in the present invention is: in order to address the above problem, to the invention provides a kind of servomotor locking device and solve the problems referred to above.
The technical solution adopted for the present invention to solve the technical problems is: a kind of servomotor locking device, comprise U-shaped jaw, hydraulic jack and base, the external part of the piston rod of described hydraulic jack is fixedly connected with U-shaped jaw, the cylinder body top of described hydraulic jack is provided with the first cylinder cap, the cylinder base of described hydraulic jack is provided with the second cylinder cap, on the first described cylinder cap outer wall, be circumferentially provided with draw-in groove, between the first described cylinder cap and U-shaped jaw, be provided with two by screw by the coated clamping block of piston rod, described clamping block wherein one end inwall has a circle lug boss, described lug boss and draw-in groove are fixed, the other end of clamping block props up U-shaped jaw.Clamping block is placed between the first cylinder cap and U-shaped jaw, locking performance matches with the draw-in groove of the first cylinder cap by one end of clamping block, the other end props up U-shaped jaw, stop the retraction of U-shaped jaw, servomotor profile is simple, take after this design, make in the maintenance process Security of water turbine units upstream more reliably, guaranteed that the person is with the safety of property.
For dismounting, carry on the outer wall at convenient, described clamping block middle part and be provided with handle.
The invention has the beneficial effects as follows, servomotor locking device of the present invention, draw-in groove by clamping block one end and the first cylinder cap is connected, the other end intercepts U-shaped jaw, realize the function that limited piston bar is retracted, two modes that clamping block is fixedly connected with by screw, make easy accessibility, have also solved cylinder cap and the larger-size problem of U-shaped jaw that screw rod Placement causes.Certainly such locking device has increased the Security of upstream unit maintenance simultaneously greatly.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the optimum embodiment's of servomotor locking device of the present invention structural representation,
Fig. 2 is the optimum embodiment's of servomotor locking device of the present invention sectional view.
In figure 1, U-shaped jaw, 2, clamping block, the 3, first cylinder cap, 4, cylinder body, the 5, second cylinder cap, 6, base, 7, draw-in groove, 8, handle, 9, lug boss.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1-2, servomotor locking device of the present invention, comprise U-shaped jaw 1, hydraulic jack and base 6, the external part of the piston rod of hydraulic jack is fixedly connected with U-shaped jaw 1, cylinder body 4 tops of hydraulic jack are provided with the first cylinder cap 3, cylinder body 4 bottoms of hydraulic jack are provided with the second cylinder cap 5, on the first cylinder cap 3 outer walls, be circumferentially provided with draw-in groove 7, between the first cylinder cap 3 and U-shaped jaw 1, be provided with two by screw by the coated clamping block 2 of piston rod, clamping block 2 wherein one end inwall has a circle lug boss 9, lug boss 9 is fixed with draw-in groove 7, the other end of clamping block 2 props up U-shaped jaw 1.
Two clamping blocks 2 that installation between the first cylinder cap 3 and U-shaped jaw 1 is closed by screw handle, after being combined, two clamping blocks 2 are dumbbell shaped, the axial one end of clamping block 2 contacts with U-shaped jaw 1, be used for intercepting U-shaped jaw 1, draw-in groove 7 on the other end and the first cylinder cap 3 is connected, after propping up, U-shaped jaw 1 just cannot be retracted, to reach the effect of locking.
On the outer wall at clamping block 2 middle parts, be provided with handle 8.In the time of easy-to-mount, hold, and carry also convenient.
The above-mentioned foundation desirable embodiment of the present invention of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to claim scope.
