Specific embodiment
Technical scheme is described further below in conjunction with accompanying drawing, but required protection domain does not limit to
In described；
As shown in Figures 1 to 3, a kind of double reinforcement hydraulic cylinder that the present invention is provided, including cylinder body 1, pushing cylinder 3, push rod 4, work
Plug A2 and piston B5, the bottom of the push rod 4 is fixed in bottom in cylinder body 1, and one end of the cylinder body 1 and pushing cylinder 3 is opening, pushes away
Cylinder 3 is inserted in cylinder body 1, and in the insertion pushing cylinder 3 of push rod 4, the piston A2 and piston B5 is on push rod 4.
In the openend insertion cylinder body 1 of the pushing cylinder 3, the seal face of such pushing cylinder 3 just can be as the stress of hydraulic pressure
Face, adds piston A2 lifting surface areas, and the reinforcement of twice causes more applicable.
The push rod 4 is hollow steel tube, is transported in pushing cylinder 3 high pressure liquid using hollow push rod 4, seals pushing cylinder 3
Pressure in end face is consistent with the pressure in the bottom of cylinder body 1, it is ensured that high pressure liquid is to the thrust on the seal face of pushing cylinder 3.
It is provided with the bottom side of the cylinder body 1, on the bottom side of push rod 4, on the side of cylinder body 1, on the side of pushing cylinder 3 logical
Fluid apertures, liquid-through hole is used to pass in and out high pressure liquid, and liquid-through hole is used to connect extraneous high-voltage tube and the bottom of cylinder body 1 on the bottom side of cylinder body 1
Space；Liquid-through hole on the bottom side of push rod 4 is used to connect the bottom space of cylinder body 1 and the inner space of push rod 4；On the side of cylinder body 1
Liquid-through hole be used for the space connected in extraneous high-voltage tube and cylinder body 1；Liquid-through hole on the side of pushing cylinder 3 is used to connect in cylinder body 1
Space and pushing cylinder 3 in space.
The piston A2 is fixed in the openend side of pushing cylinder 3, and the piston B5 is fixed in the top side of push rod 4, that is, live
Plug B5 is integrally fixed on push rod 4, and the space in pushing cylinder 3 is divided into two spaces by piston B5, and piston B5 is not moved, and is pushing cylinder 3
Medial surface is slided on piston B5 lateral surfaces；Piston A2 follows pushing cylinder to move, and the space in cylinder body 1 is divided into two spaces,
Structure design compact and reasonable.
The openend of the cylinder body 1 is provided with centring ring 8, and pushing cylinder 3 is socketed in centring ring 8, centring ring 8, piston A2 and work
Plug B5 is positioned to pushing cylinder 3 jointly, makes the motion stabilization reliability of pushing cylinder 3, and centring ring 8 also plays a part of sealed cylinder block 1.
The entire length of the pushing cylinder 3 is more than the length of cylinder body 1, to ensure to stablize pushing cylinder 3 with centring ring 8, it is ensured that this hair
Bright reliability service.Piston A2 filled sections for push rod 4 lateral surface to cylinder body 1 medial surface, piston A2 push rod 4 lateral surface with
Slided between the medial surface of cylinder body 1, it is ensured that the hydraulic oil at piston A2 two ends will not be revealed；Piston B5 filled sections are outer for push rod 4
To the medial surface of pushing cylinder 3, piston B5 slides between the lateral surface of push rod 4 and the medial surface of pushing cylinder 3 for side, it is ensured that piston B5 two
The hydraulic oil at end will not be revealed.
Each several part packaging technology of the present invention：
1. the one end of push rod 4 is fixed in the bottom centre position of cylinder body 1；
2. piston A2 and piston B5 are enclosed within push rod 4 from the other end of push rod 4 successively, and it is another that piston B5 is fixed on into push rod 4
On one end side；
3. the openend of pushing cylinder 3 is put on the skin in insert after upper glue cylinder body 1, while in piston B5 is inserted pushing cylinder 3, toward cylinder body 1
Interior pushing cylinder 3 with strength, in the barrel of pushing cylinder 3 is inserted the piston A2 slided on push rod 4, wait 4~10 minutes；
4. pushing cylinder 3 is pulled back and forth, and whether experiment pushing cylinder 3 is firm with piston A2, if insecure repetition is 3.；
5. centring ring 8 is socketed on pushing cylinder and is fixed at the openend of cylinder body 1.
Reinforcement principle：
It is arranged in certain plant equipment when by cylinder body of the invention, its high pressure liquid medium pipeline accesses the bottom side of cylinder body 1
On liquid-through hole, in the bottom space for flowing into cylinder body 1 after high pressure liquid medium flows into the liquid-through hole on cylinder body 1 bottom side, connect
The liquid-through hole from the bottom side of push rod 4 is flowed into push rod 4, is finally collected in the seal face of pushing cylinder 3 in space, the process
In, the high pressure liquid medium in the bottom space of cylinder body 1 can have thrust to piston A2, and the sealed end of pushing cylinder 3, pushing cylinder are pointed in direction
High pressure liquid medium in 3 seal faces in space equally has thrust to the sealed end of pushing cylinder 3, and two bursts of strength are added up and can produced
The huge power of life makes pushing cylinder 3 do advancing movement；When high pressure liquid medium enters fashionable from liquid-through hole on the side of cylinder body 1, high pressure liquid
Space of the medium from cylinder body 1 flows to the space in pushing cylinder 3, so that pushing cylinder 3 retracts, reaches double-acting effect.Equally, it is close
Liquid-through hole on envelope cylinder body 1 side and pushing cylinder 3 is removed, push rod 4 is changed into solid, the present invention can also be as single-acting hydraulic
Cylinder is used.
