Technical field
The present invention relates to excavator device, specifically a kind of hydraulic crawler excavator accumulator Energy release control device.
Background technology
Common accumulator effectively can not carry out proportional control release after energy regenerating, action extremely unstable when making swing arm increase, and is difficult to accomplish precise controlling.
Summary of the invention
The object of the present invention is to provide a kind of hydraulic crawler excavator accumulator Energy release control device, by electromagnetic valve, electrical proportional control is carried out to the gas mixture of accumulator, make the energy of accumulator accomplish precisely to discharge on request, solve the uncontrollable difficult problem that recovers energy.
In order to reach above-mentioned purpose, present invention employs following technical scheme, a kind of hydraulic crawler excavator accumulator Energy release control device, comprise proportional control solenoid valve, electromagnetic valve, pilot handle, swing arm energy storage oil cylinder, described proportional control solenoid valve is connected with accumulator, described pilot handle is connected with proportional control solenoid valve by electromagnetic valve, swing arm energy storage oil cylinder is separated into large chamber and loculus by the piston of therein, described proportional control solenoid valve is communicated with the large chamber of swing arm energy storage oil cylinder, and described main valve is communicated with swing arm energy storage oil cylinder loculus.
Described proportional control solenoid valve comprises valve block, spool, it is inner that described spool is arranged on valve block, at the arranged outside spring of spool, in the inner side of spool, gear groove is set, when accumulator is to swing arm energy storage oil cylinder conveying mixed oil and gas, electromagnetic valve adjusts the gear groove of spool and the A/F of valve block according to the pressure of setting at any time by spring.
Described accumulator is installed together by ball valve and valve block; Described electromagnetic valve is arranged on valve block.
Compared to prior art, the present invention has following beneficial effect:
The present invention can realize filling energy when swing arm falls, and can also carry out electrical proportional control, make the energy of accumulator accomplish precisely to discharge on request by electromagnetic valve to the gas mixture of accumulator.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of hydraulic crawler excavator accumulator Energy release control device of the present invention;
Fig. 2 is a kind of hydraulic crawler excavator accumulator of the present invention Energy release control device hydraulic system principle figure.
In figure: 1, accumulator; 2, electromagnetic valve; 3, spring; 4, spool; 5, valve block; 6, ball valve; 7, swing arm energy storage oil cylinder; 8, proportional control solenoid valve; 9, pilot handle; 10, main valve.
Detailed description of the invention
Detailed description for the present invention and technology contents, coordinate accompanying drawing to be described as follows, but accompanying drawing only provides with reference to the use with explanation, is not used for being limited the present invention.
With reference to accompanying drawing 1-2, a kind of hydraulic crawler excavator accumulator Energy release control device, comprises proportional control solenoid valve 8, electromagnetic valve 2, pilot handle 9, swing arm energy storage oil cylinder 7, and described proportional control solenoid valve is threaded connection by ball valve 6 and accumulator 1; Described pilot handle is connected by holding wire with proportional control solenoid valve by electromagnetic valve 2, swing arm energy storage oil cylinder is separated into large chamber and loculus by the piston of therein, described proportional control solenoid valve is communicated with by fluid pressure line with the large chamber of swing arm energy storage oil cylinder, and the swing arm loculus oil-out of described main valve is communicated with by fluid pressure line with swing arm energy storage oil cylinder loculus.Described proportional control solenoid valve comprises valve block 5, spool 4, it is inner that described spool 4 is arranged on valve block, at the arranged outside spring 3 of spool, in the inner side of spool, gear groove is set, when accumulator is to swing arm energy storage oil cylinder conveying mixed oil and gas, electromagnetic valve adjusts the gear groove of spool and the A/F of valve block according to the pilot pressure of setting at any time by spring.Described accumulator is installed together by ball valve and valve block; Described electromagnetic valve is arranged on valve block.
When excavator preparation, ball valve 3 is arranged to opening state;
1, energy is filled when swing arm falls: accumulator 1 is now handled pilot handle 9 to swing arm and fallen, pilot signal is passed to main valve 10, hydraulic oil is delivered in swing arm energy storage oil cylinder 7 loculus by the swing arm loculus hydraulic fluid port of main valve 10 by hydraulic pump, the energy that movable arm potential energy transforms is charged in accumulator 1 by swing arm energy storage oil cylinder 7 large chamber mixed oil and gas, and filling can be complete.
2, energy hole release: accumulator energy is under full state, put when pilot handle 9 is pushed into swing arm raise-position, pilot pressure signal is passed to electromagnetic valve 2, the electrical signal transfer of electromagnetic valve 2 makes its spool commutate to proportional control solenoid valve 8, accumulator 1 is open-minded with the hydraulic circuit in the large chamber of swing arm energy storage oil cylinder 7, accumulator 1 mesohigh mixed oil and gas is delivered to the large chamber of swing arm energy storage oil cylinder 7, and promote piston rod and stretch out, swing arm rises.When accumulator 1 carries mixed oil and gas to swing arm energy storage oil cylinder 7, electromagnetic valve 2 is produced the different signals of telecommunication according to the pressure of pilot handle and is adjusted the gear groove of spool 4 and the A/F of valve block 5 at any time, precisely controls to reach accumulator 1 fault offset.
Accumulator Energy release control device of the present invention, through in the test of hydraulic crawler excavator embarkation, can be accomplished the accurate control to the energy stored by accumulator 1 completely, and can discharge as required.
The foregoing is only preferred embodiment of the present invention, be not used to limit the scope of the claims of the present invention, other use the equivalence of patent spirit of the present invention to change, and all should all belong to the scope of the claims of the present invention.
