Description
Technical field
The present invention relates to Pneumatic hydraulic integration control technology field, refer in particular to a kind of gas-liquid for vertical jacking and damp
Cylinder.
Background technology
It is known that the working media of cylinder is compressed air, it is mainly characterized by frame for movement and control system letter thereof
Single, but its stretching speed and half-way are wayward, and affected the biggest by load change.The working media of hydraulic cylinder
Incompressible liquid, have stretching speed steadily, can midway be the most resident, load capacity is greatly and by load change shadow
The advantages such as sound, but hydraulic control system is more complicated, and in using, the faults such as pipeline leakage easily occur.Gas-liquid damping cylinder
By combination application cylinder and hydraulic cylinder, by ingenious for both advantages combination, become speed commonly used in pneumatic system or
Position control technology.
Existing gas-liquid damping cylinder generally uses the structure design that hydraulic cylinder and oil drum are the most independent, and volume is big, pipeline
Breakthrough complicated, potential is many, assemble maintenance difficult, need to improve further.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of simple in construction, volume are little, pipeline height collection
Become, easy to leak, working service be convenient, gas-liquid damping cylinder for vertical jacking.
For achieving the above object, technical scheme provided by the present invention is: a kind of gas-liquid damping cylinder for vertical jacking,
Include central hydraulic cylinder, outer layer oil storage sleeve, pneumatic cylinder cap and hydraulic control integrated cylinder seat；The wherein integrated cylinder of hydraulic control
Seat is provided with cavity of resorption and the outer layer oil storage sleeve of two respective independent hydraulic channel connection central hydraulic cylinder, and two hydraulic pressure lead to
Road is equipped with unidirectional stop valve and controls the flowing of the liquid working substance cavity of resorption outer layers oil storage sleeve from central hydraulic cylinder；Two hydraulic pressure
One in passage is additionally provided with one-way throttle valve, controls liquid working substance when unidirectional stop valve is opened from central hydraulic cylinder
The flow of chamber outer layers oil storage sleeve.
Described pneumatic linear actuator be covered with two respective independent pneumatic channel be respectively used to the epicoele of central hydraulic cylinder and
The top of outer layer oil storage sleeve controls loop with external pneumatic and is connected.
Described outer layer oil storage liner ring is arranged around central hydraulic cylinder, and is the inwall of its sleeve with hydraulic cylinder.
The present invention, after have employed such scheme, according to the principle of gas-liquid damping cylinder, by being specifically designed cylinder body, makes
Obtain the existing pneumatic convenience of the present invention, also have the stability of hydraulic pressure, can arbitrarily regulate the speed of operation, it is also possible in realization
The moment quickly and at a slow speed on way changes, and while technology such as satisfied " slow fall, fast falls, soon liter " requires, simplifies structure, tool
Have that pipeline is integrated, not easy oil leakage, volume are little, stable action, the advantage such as easy and simple to handle.
Accompanying drawing explanation
Fig. 1 is the principle schematic of the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.
See shown in accompanying drawing 1, the gas-liquid damping cylinder described in the present embodiment, it is mainly used in fall formula and folds the vertical jacking of brick machine,
It includes central hydraulic cylinder 1, outer layer oil storage sleeve 2, pneumatic cylinder cap 3 and hydraulic control integrated cylinder seat 4；Wherein, hydraulic pressure control
Integrated cylinder seat 4 processed is provided with cavity of resorption and the outer layer oil storage sleeve 2 of two respective independent hydraulic channel connection central hydraulic cylinder 1, and
And two hydraulic channels are equipped with unidirectional stop valve 5 and control the liquid working substance cavity of resorption outer layers oil storage sleeve 2 from central hydraulic cylinder 1
Flowing；One in two hydraulic channels is additionally provided with one-way throttle valve 6, controls liquid work when unidirectional stop valve 5 is opened
Matter is from the flow of the cavity of resorption outer layers oil storage sleeve 2 of central hydraulic cylinder 1.Additionally, described pneumatic cylinder cap 3 is provided with two the most solely
Vertical pneumatic channel 7,8 is respectively used to control the epicoele of central hydraulic cylinder 1 and the top of outer layer oil storage sleeve 2 with external pneumatic
Loop is connected；Described outer layer oil storage sleeve 2 is arranged around central hydraulic cylinder 1, and is the inwall of its sleeve with hydraulic cylinder.Make
Used time, the upper cavity air inlet of central hydraulic cylinder 1, open the unidirectional stop valve 5 on two hydraulic channels simultaneously, just can make gas-liquid
Piston rod 101 rapid decrease of damped cylinder；And the upper cavity air inlet of central hydraulic cylinder 1, that closes on a hydraulic channel is unidirectional
Stop valve 5, opens the unidirectional stop valve 5 on another hydraulic channel, under can making the piston rod 101 of gas-liquid damping cylinder at a slow speed
Fall；It addition, outer layers oil storage sleeve 2 gas injection, open the unidirectional stop valve 5 on a hydraulic channel simultaneously, close another liquid
Unidirectional stop valve 5 on pressure passageway, just can make piston rod 101 rapid increase of gas-liquid damping cylinder, and the above is this gas-liquid
Three kinds of work states that damped cylinder is to be realized.In a word, after using above scheme, compared to existing technology, the present invention can arbitrarily adjust
The speed that joint runs, it is also possible to the moment quickly and at a slow speed realizing midway changes, and has simple and reliable for structure, pipeline height collection
Become, easy to leak, volume be not little, stable action, the plurality of advantages such as easy and simple to handle, is a preferable gas-liquid damping cylinder, is worth pushing away
Extensively.
The examples of implementation of the above are only the preferred embodiments of the invention, not limit the enforcement model of the present invention with this
Enclose, therefore the change that all shapes according to the present invention, principle are made, all should contain within the scope of the present invention.
