Specific implementation mode
As shown in Figure 1, the structure of hydraulic continuous lifting device, including：Engine base 1, main shaft 2, eccentric wheel 3, sprocket wheel 4, axis tile
5, connecting rod 6, oil pipe 7, high-pressure common rail distributing device 8, hydraulic cylinder 9, piston 10, sealing ring 11, through bolt 12, nut 13；It is main
Axis 2 and hydraulic cylinder 9 are horizontal positioned, and hydraulic cylinder 9 is arranged side by side on 2 one or both sides of main shaft, and engine base 1 is used to support 2 He of main shaft
Hydraulic cylinder 9；Eccentric wheel 3 is connected with main shaft 2；Connecting rod 6 is located at 2 the same side of main shaft or both sides, 6 big end of connecting rod by axis tile 5, run through
Bolt 12 and the realization of nut 13 and 3 rolling assembling of eccentric wheel, i.e., can relatively rotate between 6 big end of connecting rod and eccentric wheel 3；Piston
10 are connect with 6 small end of connecting rod by flexural pivot, and sealing ring 11 is installed on 10 head of piston, and is inserted into 9 internal chamber of hydraulic cylinder, group
At piston cylinder structure；High-pressure common rail distributing device 8 is installed on each hydraulic cylinder oil inlet, for controlling hydraulic cylinder 9 into fuel-displaced；Sprocket wheel
4 synchronous rotations are assemblied on main shaft 2, and sprocket wheel 4 is used for winding hoisting hinge；Main shaft 2 continuous rotation band movable sprocket 4 winds twisted wire,
Realize continuance lifting function.
Further, 9 quantity of hydraulic cylinder can be n, and n is more than or equal to 5, and adjacent eccentric wheel 3 is according to 360 °/n of deflection
Angle be arranged.
Piston 10 is respectively arranged in each hydraulic cylinder 9 as shown in Figure 2, sealing ring 11,10 top of piston are installed in 10 head of piston
Seal oil chamber is constituted with hydraulic cylinder 9；Piston 10 is connect with 6 small end of connecting rod by flexural pivot 14, and 6 big end of connecting rod is then tightly attached to eccentric wheel
It on 3, is waled by axis tile 5, ensures that 6 big end of connecting rod is not detached from eccentric wheel 3.
As shown in Fig. 3, eccentric wheel 3 and main shaft 2 are fixedly mounted, and with 2 synchronous rotary of main shaft.According to the original of uniform force
Then, each eccentric wheel deflection angle difference should be 72 ° (φ=360 °/n, n be hydraulic cylinder number, herein n be 5).
As shown in Fig. 4, single hydraulic cylinder works principle：When the eccentric wheel of hydraulic motor is in position shown in Fig. 4,
High-pressure common rail distributing device 8 controls high pressure oil and enters hydraulic cylinder 9, and high pressure oil generates a downward thrust F to piston to be led to
The axis for crossing connecting rod 6 is transmitted on eccentric wheel 3, and directs at the center of circle O1 of eccentric wheel 3.Due to the center line O of O1 and output shaft it
Between have eccentric distance e, so, by F generate tangential force FN will form torque to output shaft, make its do clockwise time
Turn.When the piston 10 into oil cylinder (hydraulic cylinder 9 for entering high pressure oil) reaches lower dead center under the promotion of oil pressure, i.e. O1 is in O
Underface when, 8 control cylinder of high-pressure common rail distributing device carries out oil extraction, immediately 10 uplink of piston.Work under oil extraction state
Plug 10 with main axis reach top dead centre when, i.e. when O1 be in the surface of O, high-pressure common rail distributing device 8 control high pressure oil into
Enter hydraulic cylinder 9, piston 10 is under the promotion of high pressure oil again to main shaft work done.Analysis can obtain, when hydraulic cylinder number n is odd number
When, the oil cylinder quantity m worked at the same time is up to：M=(n+1)/2, the oil cylinder quantity m worked at the same time are at least：M=(n+1)/2-
1；When hydraulic cylinder number n is even number, the oil cylinder quantity m worked at the same time is up to：M=n/2, the oil cylinder quantity m worked at the same time
It is at least：M=n/2-1, therefore meet hydraulic cylinder quantity n >=5 can ensure that device can be in the cylinder that subtracts 1 (the 5 cylinders cylinder that can at most subtract 2
Operation) in the case of continue working.And the working efficiency of odd number cylinder is better than even number cylinder.
As shown in Fig. 5, hydraulic cylinder cylinder diameter is D, length of connecting rod L, link width b, and main shaft radius is r, eccentric wheel
Radius is R, and eccentricity e, hydraulic cylinder installation site skirt bottom is H, connecting rod maximum pendulum angle θ away from main-shaft core linear distance.It can be with
It obtains, the impulse stroke of piston is 2e；To ensure mechanism normal work, cannot be touched with hydraulic cylinder skirt section when connecting rod swings
It hits, it is therefore desirable to meet relationship：
As shown in Fig. 6, in the case of full-load operation, since the eccentric wheel that 5 hydraulic cylinders are connected is mutually staggered with main shaft
72 ° of angles can guarantee that at least two hydraulic cylinder to main shaft work done, continues so that main shaft is stablized to a direction always
It rotates, drives the sprocket wheel rotation being mounted on main shaft, realize continuance lifting function.By setting high-pressure common rail distributing device
To each hydraulic cylinder with oil sequence, the rotating forward and reverse rotation of main shaft may be implemented.In the case where loading smaller, height can be passed through
Pressure common rail distributing device makes 1 or 2 hydraulic cylinders be connected to oil return box, does not supply high pressure liquid pressure oil, its is made to accompany motion of main shaft.
Since the eccentric wheel that two neighboring hydraulic cylinder is connected mutually staggers 144 ° of angles with main shaft, at least one hydraulic cylinder is always had
In stroke in work, equipment remains to work normally, this to subtract cylinder operation and reduce energy consumption, improves economic performance.
The above described is only a preferred embodiment of the present invention, be not intended to limit the present invention in any form, though
So the present invention has been disclosed as a preferred embodiment, and however, it is not intended to limit the invention, any technology people for being familiar with this profession
Member without departing from the scope of the present invention, when the technology contents using the disclosure above make it is a little change or be modified to
