Description
Technical field
The invention belongs to Energy Saving Technology by Hydraulic Pressure field, it is related to a kind of three hydraulic fluid port hydraulic pressure dress recycled for gravitional force
Put.
Background technology
Hydraulic system is automatically controlled due to having the advantages that power density is big, being easily achieved, and is widely used in multiple necks
Domain, but there is the low shortcoming of high energy consumption, efficiency simultaneously, efficiency turns into a leading indicator for weighing hydraulic test.It is right
In the operating mode with gravitional force, the function of former hydraulic test can both be ensured by appropriate device, again can be by gravitional force
Recycled, so as to improve system effectiveness, reduce installed power, realize the purpose of energy-conservation.
At present, realizing the mode of the recycling of gravitional force mainly has three kinds of modes, respectively mechanical energy recovery, electric energy
Reclaim, hydraulic energy is reclaimed.Section tool energy way of recycling generally carries out gravitional force recovery, the part of use in the way of mechanical connection
It is conventional to have the mechanical devices such as mechanical counterweight, spring, flywheel；It is that by conversion equipment gravitional force is converted into electricity that electric energy, which is reclaimed,
Can, feed back to using energy-storage travelling wave tubes such as batteries or directly power network；The recoverable mode of hydraulic pressure is main using hydraulic accumulator as storage
Energy element, is recycled to gravitional force in the form of hydraulic energy.
In hydraulic accumulator carries out by the way of gravitional force recycling, hydraulic control circuit is used at present and is cut
Change accumulator and carry out energy storage, loop is complicated, need are electric, automatically control carry out action cooperation.
The content of the invention
In view of this, it is an object of the invention to provide a kind of three hydraulic fluid port hydraulic pressure dress recycled for gravitional force
Put.
To reach above-mentioned purpose, the present invention provides following technical scheme：
A kind of three hydraulic fluid port hydraulic means recycled for gravitional force, including accumulator, cylinder body, piston, control oil
Equipment, hydraulic cylinder, the piston is arranged in cylinder body is separated into piston rod control chamber, middle control successively by the inner chamber of cylinder body
Chamber, piston control chamber, the accumulator are connected with piston rod control chamber, and the oily equipment of control is connected with middle control chamber, institute
The gravity load chamber for stating hydraulic cylinder is connected with piston control chamber.
Further, the oily equipment of the control is connected by controlling pump or control valve with middle control chamber.
Further, the hydraulic cylinder is single-action hydraulic cylinder or double acting hydraulic cylinder.
Further, the accumulator is that spring accumul ator or bladder accumulator or weighted accumulator or piston type store
Can device.
The beneficial effects of the present invention are：
1st, the present invention by with the use of the control of Driven by Hydraulic Cylinder gravity load chamber be split as two control chambers, a control
Chamber processed is controlled using former control mode, another control chamber using accumulator, operating pressure and the gravity load size of accumulator
Matching, during gravity load up and down motion, accumulator absorbs gravitional force, so as to reduce the driving work(of former control mode
Rate, reduces hydraulic system installed power, reduces operation energy consumption, saves the energy；
2nd, it is former without change without civil engineering present invention is particularly suitable for the Hydraulic System with gravity load
Hydraulic system, oil cylinder, electrical control etc., only need to increase Patent equipment of the present invention, you can realize the purpose of energy-conservation.
Brief description of the drawings
In order that the purpose of the present invention, technical scheme and beneficial effect are clearer, the present invention provides drawings described below and carried out
Explanation：
Fig. 1 is structural representation of the invention.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
As shown in Figure 1 it is a kind of for gravitional force recycle three hydraulic fluid port hydraulic means, including accumulator 4, cylinder body 1,
Piston 2, the oily equipment 3 of control, hydraulic cylinder 5, piston 2 are arranged in cylinder body 1 inner chamber of cylinder body 1 being separated into piston rod control successively
Chamber 7, middle control chamber 8, piston control chamber 9, the left end of the present embodiment piston 2 are slidably matched with the wall neck of cylinder body 1, right-hand member piston
The right part of cylinder body 1 is separated into middle control chamber 8 and piston control chamber 9 by part.Accumulator 4 is connected with piston rod control chamber 7, control
Liquefaction equipment 3 is connected with middle control chamber 8, and the gravity load chamber of hydraulic cylinder 5 is connected with piston control chamber 9.The oily equipment 3 of control is led to
Cross controlling pump or control valve to connect with middle control chamber, it is possible to achieve pump control or valve control, can also for the control of control oil
It is controlled by servo control mechanism.Hydraulic cylinder can be single-action hydraulic cylinder or double acting hydraulic cylinder.The accumulator 4 of the present embodiment
For bladder accumulator, the power that the operating pressure effect of filling nitrogen is produced on the piston rod is suitable with 6 gravity of load.This area
Technical staff is appreciated that accumulator can also be spring accumul ator or bladder accumulator or weighted accumulator or piston
Formula accumulator.
When load 6 needs to rise, control oil is by controlling the oil oil-feed of equipment 3, and pressure oil enters middle control chamber 8, living
What stopper rod control chamber 7 and middle control chamber 8 were produced makes a concerted effort to promote piston 2 to move right, so that by the fluid in piston control chamber 9
Hydraulic cylinder 5 is pressed into, so that the driving gravity load chamber cavity of resorption of hydraulic cylinder 5, causes the piston of hydraulic cylinder 5 to rise, so as to realize negative
Carry 6 to rise, piston rod control chamber 7 needs the volume filled to be provided by accumulator 4.
When load 6 needs to decline, control oil is by controlling the oil oil extraction of equipment 3, and the pressure oil of middle control chamber 8 passes through control
Liquefaction is discharged, and piston control chamber 9 promotes piston portion 2 to left movement, so that hydraulic cylinder 5 to be driven to the oil of gravity load chamber cavity of resorption
Liquid is discharged into piston control chamber 9, causes the piston of hydraulic cylinder 5 to decline, so as to realize that load 6 declines, in piston rod control chamber 7
In fluid press-in accumulator 4.
Finally illustrate, preferred embodiment above is merely illustrative of the technical solution of the present invention and unrestricted, although logical
Cross above preferred embodiment the present invention is described in detail, it is to be understood by those skilled in the art that can be
Various changes are made to it in form and in details, without departing from claims of the present invention limited range.
