Connect；The rod chamber of master cylinder is connected by connecting tube respectively with the rod chamber of described two auxiliary oil cylinders, the master cylinder without bar
Chamber is connected by connecting tube respectively with the rodless cavity of described two auxiliary oil cylinders.
Slide plate is slidably connected on the cylinder body of each hydraulic cylinder, the both ends of the slide plate are fixed with the branch being parallel to each other
Plate；The two support plate other ends are fixedly connected with round bar；The piston rod end of the master cylinder is provided with circular hole, and the round bar passes through
The circular hole of piston rod end.
It is further：The piston rod end of the master cylinder is provided with fuel feed hole and oil outlet, is provided with the piston rod
The oil inlet passage and oil discharge passage corresponding with the fuel feed hole and oil outlet respectively, the oil inlet passage and oil discharge passage with
The rod chamber of master cylinder connects with rodless cavity.
Each cylinder body is welded to connect in joint face.
The connecting tube is high pressure resistant seamless steel pipe.
The present invention ensures enough jacking oil pressure, master cylinder pair cylinder simultaneous retractable, raising landing using multiple single-unit hydraulic cylinders
Response is fast；Multi-hydraulic-cylinder reversed arrangement increase jacking stroke；Using three cylinder arrangements, the stability of strutting system of triangle is borrowed,
It may be such that the structure on raising dam is more firm, the guide support structure formed using slide plate, round bar, support plate, further ensure,
Jack the reliability of oil pressure；Asphalt channel is arranged in the piston rod of master cylinder, is simplified exterior line structure, is avoided making for flexible pipe
With, pipeline will not move back and forth with the flexible of hydraulic cylinder, avoid pipeline aging and produce the risk of oil leak permeability, it is safer can
Lean on.
Compared with prior art, it is of the invention beneficial to being：Realize while ensureing to jack stroke that to enhance structure steady
Qualitative, lifting dynamics foot, flood fighting hydraulic impact is strong, safe, extends the service life of hydraulic cylinder, has stronger practicality
Property.

Embodiment
It is the specific embodiment of the present invention below, in conjunction with accompanying drawing, the present invention will be further described.
As shown in figure 1, a kind of hydraulic means on hydraulic lifting dam, including the hydraulic pump being sequentially connected, hydraulic cylinder and oil return
Case.Hydraulic cylinder support is connected to the land side of movable dam plate 1, and hydraulic cylinder includes the auxiliary oil cylinder located at middle master cylinder 2 and both sides
3, master cylinder 2 and the reversed arrangement of auxiliary oil cylinder 3, the cylinder body 10 of each hydraulic cylinder are welded to connect in joint face.The rod chamber of master cylinder 2
Connected respectively by connecting tube 7 with the rod chamber of two auxiliary oil cylinders 3, the rodless cavity of the rodless cavity of master cylinder 2 and two auxiliary oil cylinders 3
Connected respectively by connecting tube 7.
Slide plate 6 is slidably connected on the cylinder body 10 of each hydraulic cylinder, the both ends of slide plate 6 are fixed with the support plate 9 being parallel to each other；Two
The other end of support plate 9 is fixedly connected with round bar 8；The end of piston rod 20 of master cylinder 2 is provided with circular hole, and round bar 8 passes through the end of piston rod 20
The circular hole in portion.Round bar 8 passes through hinge axis connection, piston rod 20 and the 1 corresponding position of movable dam plate of both sides auxiliary oil cylinder 3 with undersetting 4
The upper bracket 5 put passes through hinge axis connection.The stability of strutting system of triangle is borrowed, may be such that the structure on whole raising dam more
Firm, support is more stable.Such arrangement not only can obtain very stable support effect but also reversed arrangement can increase liquid
The jacking stroke of cylinder pressure, so as to ensure that the scope of activities of movable dam plate 1 is larger.
The end of piston rod 20 of master cylinder 2 is provided with fuel feed hole and oil outlet, and oil inlet passage is provided with piston rod 20 and is gone out
Oily passage, oil inlet passage connect with fuel feed hole, and oil discharge passage connects with oil outlet, and each asphalt channel has bar with master cylinder 2
Chamber end connects with rodless cavity end, by same the stretching with contracting for entering fuel-displaced each oil cylinder of cooperation completion.Asphalt channel is located at piston rod
In 20, connect to be placed in piston rod 20 respectively by the oil inlet and outlet of the end of piston rod 20 and enter oil road, shorten outside oil
The length of pipe, simplifies exterior line structure, and pipeline is relatively fixed motionless, will not be moved back and forth with oil cylinder is flexible, so as to more stable,
Securely and reliably.Connecting tube 7 uses high pressure resistant seamless steel pipe, has abandoned the use of consistent lubricant pipe, avoids leaking caused by pipeline aging
The risk of oily permeability, ensure the durability and security of pipeline.
Movable dam plate can be designed to according to river course developed width by list fan dam plate or more fan dam plates, respectively with rubber between fan dam plate
