Abstract
A kind of hydraulic support system, including pumping plant, oil cylinder, synchronous valve, solenoid directional control valve；By oil pipe, pumping plant connects solenoid directional control valve, and the import of solenoid directional control valve connecting balanced valve, balancing valve outlet is connected with hydraulic control one-way valve import, fluid-control one-way valve outlet is connected with oil cylinder rodless cavity, and the control port of balanced valve is connected by synchronous valve with the rod chamber of oil cylinder.Due to employing balanced valve in system, balanced valve can be together integrated on valve block with hydraulic control one-way valve, synchronous valve, solenoid directional control valve, greatly reduce the space of pumping plant；And the support system for carrying accumulator is big volume first, and accumulator must be equipped with accumulator safety valve, and accumulator safety valve is switched on when every time using accumulator, and the support system with balanced valve simplifies this operation.
Description
Technical field
The utility model belongs to machinery equipment field, and in particular to a kind of hydraulic support system.
Background technology
In practical application equipment, ballast support system is to support weight by oil cylinder, and after ensureing system-down, oil
Cylinder can be by the self-locking system of itself, it is ensured that weight does not fall in stop position because of the self gravitation of weight, traditionally
All it is that oil cylinder self-locking is ensured using hydraulically-controlled one-way valve and accumulator, such system has the disadvantage that volume is big, cumbersome, the system
By the combination of hydraulically-controlled one-way valve and cartridge balanced valve, overcome the shortcoming of existing system, be greatly reduced pumping plant volume,
Operating procedure is simplified, it is more economical, more reliable.
The content of the invention
The purpose of this utility model is achieved by the following technical solution：Changed including pumping plant, oil cylinder, synchronous valve, electromagnetism
To valve；Pumping plant is set to connect solenoid directional control valve, the import of solenoid directional control valve connecting balanced valve, balancing valve outlet and hydraulic control by oil pipe
Check valve inlet is connected, and fluid-control one-way valve outlet is connected with oil cylinder rodless cavity, and the control port of balanced valve is by synchronous valve and oil
The rod chamber of cylinder is connected.
Due to employing balanced valve in system, balanced valve can together collect with hydraulic control one-way valve, synchronous valve, solenoid directional control valve
Into on valve block, the space of pumping plant is greatly reduced；And the support system for carrying accumulator is volume big first, and accumulation of energy
Device must be equipped with accumulator safety valve, be switched on accumulator safety valve when every time using accumulator, the support with balanced valve
System simplifies this operation.

Specific embodiment
Including pumping plant（1）, oil cylinder（5）, synchronous valve（6）, solenoid directional control valve（2）；Pumping plant is made by oil pipe（1）Connection electromagnetism
Reversal valve（2）, solenoid directional control valve（2）Connecting balanced valve（3）Oil inlet, balanced valve（6）Oil-out and hydraulic control one-way valve（4）Enter
Hydraulic fluid port is connected, hydraulic control one-way valve（4）Outlet and oil cylinder rodless cavity（7）It is connected, balanced valve（3）Control port（9）By synchronization
Valve（6）With oil cylinder（5）Cylinder rod chamber（8）It is connected.
During work, solenoid directional control valve（2）Connect, pressure oil is through pumping plant（1）, solenoid directional control valve（2）, synchronous valve（6）Into
Cylinder rod chamber（8）, now pressure oil is by balanced valve（3）Control port（9）And hydraulic control one-way valve（4）Control port（10）
By balanced valve（3）It is equal with hydraulic control one-way valve（4）Open, oil cylinder（5）Middle rodless cavity（7）Hydraulic oil through hydraulic control one-way valve（4）, it is flat
Weighing apparatus valve（3）, solenoid directional control valve（2）Fuel tank is flowed back to, piston rod is retracted, weight-drop.Work as pumping plant（1）With solenoid directional control valve（2）
During power-off, balanced valve（3）And hydraulic control one-way valve（4）Control port all no pressures, balanced valve（3）And hydraulic control one-way valve（4）
Close, balanced valve（3）And hydraulic control one-way valve（4）Double interlock is realized, piston rod stopping action, weight stops falling.
