Specific embodiment
The technical solution of the utility model is described further below in conjunction with accompanying drawing, but required protection domain is not
It is confined to described；
As shown in Figures 1 to 3, a kind of reinforcement hydraulic cylinder that the utility model 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 reality
Use new reliability service.Piston A2 filled sections are the lateral surface of push rod 4 to the medial surface of cylinder body 1, and piston A2 is in the outside of push rod 4
Slided between the medial surface of face and cylinder body 1, it is ensured that the hydraulic oil at piston A2 two ends will not be revealed；Piston B5 filled sections are push rod 4
Lateral surface to pushing cylinder 3 medial surface, piston B5 slides between the lateral surface of push rod 4 and the medial surface of pushing cylinder 3, it is ensured that piston
The hydraulic oil at B5 two ends will not be revealed.
The utility model each several part packaging technology：
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 present utility model, its high pressure liquid medium pipeline accesses the bottom of cylinder body 1
Liquid-through hole on side, flows into the bottom space of cylinder body 1 after high pressure liquid medium flows into the liquid-through hole on the bottom side of cylinder body 1
In, then 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,
During being somebody's turn to do, the high pressure liquid medium in the bottom space of cylinder body 1 can have thrust to piston A2, and direction is pointed to pushing cylinder 3 and sealed
End, the high pressure liquid medium in the seal face of pushing cylinder 3 in space equally has thrust to the sealed end of pushing cylinder 3, and two bursts of strength add
Getting up to produce huge power makes pushing cylinder 3 do advancing movement；When high pressure liquid medium enters from liquid-through hole on the side of cylinder body 1
When, space of the high pressure liquid medium from cylinder body 1 flows to the space in pushing cylinder 3, so that pushing cylinder 3 retracts, reaches double-acting effect
Really.Equally, the liquid-through hole on the side of sealed cylinder block 1 and pushing cylinder 3 is removed, push rod 4 is changed into solid, the utility model can be with
Used as single-action hydraulic cylinder.
