Description
Technical field
It the utility model is related to a kind of piston type servomotor attaching/detaching apparatus, and in particular to hydroelectric power plant's machine unit speed regulating device servomotor
The disassembling operations device of piston rod.
Background technology
During machine unit speed regulating device system overhaul, governor servomotor piston rod and connecting plate are disengaged, can be replaced corresponding
Sealing.When disengaging servomotor piston rod with connecting plate, large-scale open-end wrench clamping piston rod need to be used, service personnel strikes by sledgehammer
The handle of open-end wrench is hit, drives piston rod rotation.Since piston rod is steel structure, bulky, heavier mass, adjusted
More people's coordinating operations are needed in journey, labor intensity is big, dangerous high.The open-end wrench of this size is non-standard, as scene is cut
Cut and form, since stress is larger during maintenance, be also easy to produce deformation, can not reuse.
The content of the invention
The utility model main purpose is to overcome the shortcomings of that original servomotor piston-rod volume is big, quality is heavy, dangerous big,
A kind of piston rod attaching/detaching apparatus of piston type servomotor simple in structure, easy to operate is provided.
The above-mentioned technical problem of the utility model is mainly what is be addressed by following technical proposals：A kind of piston type connects
Power device attaching/detaching apparatus, it includes：
Combined type taps spanner, has bar-shaped body；The end of body sets through hole, and middle part, which is set, can cover on the piston rod with band
The mesoporous that piston bar rotates；
Chain block, the rotation that spanner is tapped for combined type provide tractive force；
And steel wire rope, one end are securable to the through hole of the body end, the other end is drawn by the chain block.
Through the above technical solutions, only combined type need to be tapped to spanner set on the piston rod, chain block, steel are sequentially connected
Cord and spanner through hole, drawing spanner by chain block can drive piston rod to rotate, time saving, laborsaving；Overall structure letter
Single, light-weight, when use, is safe and reliable and reusable.
Brief description of the drawings
Attached drawing 1 is that the combined type of the utility model taps a kind of structure diagram of spanner.
Attached drawing 2 is the side view of attached drawing 1.
Wherein：1st, upper structure；2nd, lower structure body；3rd, bolt.
Embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
Embodiment：A kind of piston type servomotor attaching/detaching apparatus of the utility model, it includes：Combined type taps spanner, such as attached
Shown in Fig. 1, attached drawing 2, there is bar-shaped body；The end of body sets through hole, and middle part, which is set, can cover on the piston rod to drive piston rod
The mesoporous of rotation；Chain block, the rotation that spanner is tapped for combined type provide tractive force；And steel wire rope, one end are securable to
Combined type taps the through hole of wrench body end, and the other end is drawn by the chain block.
Combined type taps the two-part structure that the body of spanner disconnects for middle part, including upper structure 1 and lower structure body 2,
The connecting portion of upper structure 1 and lower structure body 2 is in the middle part of body.The knot assembled using upper structure 1 and lower structure body 2
Structure, unclamps bolt and is split as two bodies, you can reduce overall volume, it is easier to carries and stores.
Connected between upper structure 1 and lower structure body 2 by two bolts 3；Two bolts 3 are split in the both sides of the mesoporous.
Bolt closing, hold tightly on the piston rod, avoid spanner from integrally dropping, improve security by upper structure 1 and lower structure body 2.
Mesoporous is square hole, and the pair of horns of the square hole is split on upper structure 1 and lower structure body 2, another diagonally by upper knot
Structure body 1 and lower structure body 2 are enclosed in engaging portion to be formed；So that the center line general parallel orientation of a pair of of linea angulata and body, another diagonal
On faying face and with the median perpendicular of body.This structure, symmetrical configuration, it is easier to make, and there is good exchange
Property；Stress is more balanced during use, is unlikely to deform.Especially, after using this structure, mesoporous has a variety of different double team rulers
It is very little, i.e.,：When the size of piston rod is more than intermediate pore size, it is upper between structure 1 and lower structure body 2 to can still be by bolt increase
Away from until mesoporous can clamp the piston rod.When clamping dimension is more than the piston rod of mesoporous, during elasticity bolt can increase or reduce
The size that hole sandwiches, makes mesoporous adapt to different piston rod sizes, adapts to the servomotor piston of different units, different size
Bar.
In use, combined type is tapped spanner set on the piston rod, chain block, steel wire rope, shackle are sequentially connected with pulling
Hand through hole, draws spanner to drive piston rod to rotate by chain block.
For former governor servomotor piston rod dismantling device is bulky, heavier mass, it is dangerous big the shortcomings of, originally tear open
Assembling device taps spanner using combined type and coordinates with chain block, to drive piston rod to rotate, avoids operating personnel narrow and small
Danger during spanner is tapped in space, saves muscle power, while it also avoid the risk that open-end wrench drops, when shortening operation
Between.
Combined type percussion spanner is made using 40Cr steel forgings to be formed, and modifier treatment is first carried out after the completion of manufacture, and surface is sent out again
Black processing.For spanner to divide valve combined type, junction hexagon socket head cap screw is tight crossed belt, holds tightly on the piston rod, avoids operation
During spanner drop.Spanner is elastic adjustable to adapt to different piston rod sizes hexagon socket head cap screw at conjunction, adapts to
The size of the servomotor piston rod of different units, while the machining accuracy of the spanner also reduced.Spanner is provided with Φ 30mm in afterbody
Through hole and part can be tapped, with adapt to it is different maintenance environment under uses.
Present embodiment is simple and practical, and device is reusable, and environmental suitability is strong, works well.
While there has been shown and described that the embodiment of the utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from the principle of the utility model and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
