The rodless cavity of cylinder and rod chamber are connected with A hydraulic fluid port and the B hydraulic fluid port of 3-position 4-way electro-hydraulic reversing valve respectively by pipeline；Push pedal oil cylinder
The each road binders road in parallel in rodless cavity loop and rod chamber loop, converge after connecting rodless cavity check valve and rod chamber check valve respectively
Close, more successively connect access oil return line T after one-way throttle valve and 2/2-way solenoid directional control valve.
This bulky refuse station push pedal impact-reducing hydraulic system push pedal oil cylinder stretch out motion actuated during, 3-position 4-way electricity
Liquid reversal valve left end electric magnet obtains the electric P mouth making this valve and A mouth UNICOM, and big flow pressure oil enters push pedal oil cylinder by this path
Rodless cavity promote piston rod to stretch out thus promote push pedal to advance, electro-hydraulic reversing valve obtain electric while, 2/2-way electromagnetism changes
To valve also electric, rodless cavity loop feature oil enters oil return line oil return by this 2/2-way solenoid directional control valve, thus slows down nothing
Bar chamber oil circuit is built and is pressed through journey, reaches to reduce the purpose starting impact；In push pedal oil cylinder stretches out motion stopped process, electro-hydraulic commutation
Valve electric magnet dead electricity, the PTAB Kou Hubu UNICOM of this valve, solenoid directional control valve obtains electric simultaneously, and rod chamber loop feature oil is by this valve
Enter oil return line oil return, thus slow down the braking of rod chamber oil circuit and build and press through journey, reach to reduce the purpose stopping impact.Push pedal oil cylinder
Startup and the stopped process regained are as the same.
The bulky refuse station push pedal impact-reducing hydraulic system of said structure is by big flow 3-position 4-way electro-hydraulic reversing valve control
Moving forward and backward of push pedal oil cylinder processed, in rod chamber and the road low discharge pipeline oil return in parallel respectively of rodless cavity loop of oil cylinder
Case, by connecting with fuel tank when starting with stopped process, part draining thus slow down the startup of oil cylinder and build and press through journey and braking
Build and press through journey, thus reduce the acceleration started with stopped process and reach to reduce the purpose of impact.
By repetition test, this utility model bulky refuse station push pedal impact-reducing hydraulic system can effectively slow down startup and
Stop impact, thus solve because plate pushing structure is damaged and the problem of sound pollution by impact.
Accompanying drawing explanation
Fig. 1 is this utility model bulky refuse station push pedal impact-reducing hydraulic system structure schematic diagram.
Reference: 3-position 4-way electro-hydraulic reversing valve 1, push pedal oil cylinder 2, rod chamber check valve 3.1, rodless cavity check valve
3.2, one-way throttle valve 4,2/2-way solenoid directional control valve 5.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model bulky refuse station push pedal impact-reducing hydraulic system is made
Further describe.
As it is shown in figure 1, this utility model bulky refuse station push pedal impact-reducing hydraulic system include big flow pressure oil sources, three
Position four-way electro-hydraulic reversing valve 1, push pedal oil cylinder 2, rod chamber check valve 3.1, rodless cavity check valve 3.2, one-way throttle valve 4, two
Two electric change valve 5 and fluid pressure lines；Big flow pressure oil P links the P mouth of 3-position 4-way electro-hydraulic reversing valve 1 by pipeline,
The rodless cavity of push pedal oil cylinder 2 and rod chamber are connected with A hydraulic fluid port and the B hydraulic fluid port of 3-position 4-way electro-hydraulic reversing valve 1 respectively by pipeline,
The each road binders road in parallel in the rodless cavity loop of push pedal oil cylinder 2 and rod chamber loop, connects rodless cavity check valve 3.2 respectively and has bar
Converge after chamber check valve 3.1, more successively connect access oil return line T after one-way throttle valve 4 and 2/2-way solenoid directional control valve 5.
During work, push pedal oil cylinder 2 stretch out motion actuated during, 3-position 4-way electro-hydraulic reversing valve 1 left end electric magnet obtains
Electricity makes P mouth and the A mouth UNICOM of this valve, and big flow pressure oil P enters the rodless cavity of push pedal oil cylinder 2 by this path, three simultaneously
The B mouth of four-way electro-hydraulic reversing valve 1 and T mouth UNICOM, rod chamber oil flows into oil return line T oil return from this path, thus promotes piston rod
Stretch out, promote push pedal to advance；3-position 4-way electro-hydraulic reversing valve 1 left end electric magnet obtain electric while, 2/2-way electromagnetic switch
Valve 5 electric magnet also electric, the rodless cavity loop feature oil of push pedal oil cylinder 2 pass through rodless cavity check valve 3.2, one-way throttle valve 4 and
2/2-way solenoid directional control valve 5 enters oil return line T oil return, thus slows down rodless cavity oil circuit and build and press through journey, reaches to reduce and starts punching
The purpose hit, rod chamber check valve 3.1 is closed and is prevented two chamber string oil simultaneously, builds the speed of pressure by regulation one-way throttle valve 4
Opening is adjusted；After start-up course completes, 2/2-way solenoid directional control valve 5 electric magnet dead electricity, this valve cuts out.At push pedal oil
Cylinder 2 stretches out in motion stopped process, 3-position 4-way electro-hydraulic reversing valve 1 left end electric magnet dead electricity, and the PTAB mouth of this valve is connected the most mutually
Logical, 2/2-way solenoid directional control valve 5 electric magnet obtains electric simultaneously, and push pedal oil cylinder 2 rod chamber loop feature oil is unidirectional by rod chamber
Valve 3.1, one-way throttle valve 4 and 2/2-way solenoid directional control valve 5 enter oil return line T oil return, thus slow down the braking of rod chamber oil circuit
Building and press through journey, reach to reduce the purpose stopping impact, rodless cavity check valve 3.2 is closed and is prevented two chamber string oil simultaneously, builds the speed of pressure
Spend and be adjusted by the opening of regulation one-way throttle valve 4；After stopped process completes, 2/2-way solenoid directional control valve 5 electromagnetism
Ferrum dead electricity, this valve cuts out.Startup and stopped process that push pedal oil cylinder 2 is regained are as the same.
In view of the foregoing it is apparent that this hydraulic system can well realize slowing down the startup of push pedal oil cylinder and stopping punching
Hit, thus avoid the occurrence of impact and structure is damaged the situation being simultaneously emitted by the biggest work noise.
