Description

Hydraulic crawler excavator accumulator Energy release control device
Technical field
The utility model relates to excavator device, specifically a kind of hydraulic crawler excavator accumulator Energy release control device.
Background technology
Common accumulator can not effectively carry out proportional control release after energy reclaims, while making swing arm increase action extremely unstable, be difficult to accomplish meticulous control.
Summary of the invention
The purpose of this utility model is to provide a kind of hydraulic crawler excavator accumulator Energy release control device, by electromagnetic valve, the gas mixture of accumulator is carried out to electronics proportional control, make the energy of accumulator accomplish precisely to discharge on request, solved the uncontrollable difficult problem that recovers energy.
The purpose of this utility model can realize by following technical solution:
This hydraulic crawler excavator accumulator Energy release control device comprises solenoid-operated proportional control valve, electromagnetic valve, pilot handle, swing arm energy storage oil cylinder, described solenoid-operated proportional control valve is connected with accumulator, described pilot handle is connected with solenoid-operated proportional control valve by electromagnetic valve, swing arm energy storage oil cylinder is separated into large chamber and loculus by the piston of self inside, described solenoid-operated proportional control 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.
The purpose of this utility model also can realize by following technical solution:
Further, described in this hydraulic crawler excavator accumulator Energy release control device, solenoid-operated proportional control valve comprises valve piece, spool, it is inner that described spool is arranged on valve piece, arranged outside spring at spool, in the inner side of spool, gear groove is set, when accumulator is carried mixed oil and gas to swing arm energy storage oil cylinder, electromagnetic valve is adjusted the gear groove of spool and the A/F of valve piece according to the pressure of setting at any time by spring.
Further, described in this hydraulic crawler excavator accumulator Energy release control device, accumulator is installed together by ball valve and valve piece; Described electromagnetic valve is arranged on valve piece.
Compared to prior art, the utlity model has following beneficial effect:
The utility model can be realized when swing arm falls and fill energy, can also to the gas mixture of accumulator, carry out electronics proportional control by electromagnetic valve, makes the energy of accumulator accomplish precisely to discharge on request.
Accompanying drawing explanation
Fig. 1 is the structural representation of hydraulic crawler excavator accumulator Energy release control device of the present utility model;
Fig. 2 is the utility model hydraulic crawler excavator accumulator Energy release control device hydraulic system principle figure.
In figure: 1, accumulator; 2, electromagnetic valve; 3, spring; 4, spool; 5, valve piece; 6, ball valve; 7, swing arm energy storage oil cylinder; 8, solenoid-operated proportional control valve; 9, pilot handle; 10, main valve.
The specific embodiment
Relevant detailed description of the present utility model and technology contents, coordinate accompanying drawing to be described as follows, yet accompanying drawing only provides the use of reference with explanation, is not used for the utility model to be limited.
With reference to accompanying drawing 1-2, this hydraulic crawler excavator accumulator Energy release control device comprises solenoid-operated proportional control valve 8, electromagnetic valve 2, pilot handle 9, swing arm energy storage oil cylinder 7, and described solenoid-operated proportional control valve is threaded connection by ball valve 6 and accumulator 1; Described pilot handle is connected by holding wire with solenoid-operated proportional control valve by electromagnetic valve 2, swing arm energy storage oil cylinder is separated into large chamber and loculus by the piston of self inside, described solenoid-operated proportional control 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 solenoid-operated proportional control valve comprises valve piece 5, spool 4, it is inner that described spool 4 is arranged on valve piece, arranged outside spring 3 at spool, in the inner side of spool, gear groove is set, when accumulator is carried mixed oil and gas to swing arm energy storage oil cylinder, electromagnetic valve is adjusted the gear groove of spool and the A/F of valve piece according to the pilot pressure of setting at any time by spring.Described accumulator is installed together by ball valve and valve piece; Described electromagnetic valve is arranged on valve piece.
When excavator preparation, ball valve 3 is arranged to opening state;
When 1, swing arm falls, fill energy: accumulator 1 is now handled pilot handle 9 to swing arm and fallen, pilot signal is passed to main valve 10, by hydraulic oil, the swing arm loculus hydraulic fluid port by main valve 10 is delivered in swing arm energy storage oil cylinder 7 loculuses 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 is controlled and is discharged: accumulator energy is under full state, when being pushed into swing arm raise-position, puts pilot handle 9, pilot pressure signal is passed to electromagnetic valve 2, the electrical signal transfer of electromagnetic valve 2 makes its spool commutation to solenoid-operated proportional control valve 8, accumulator 1 is open-minded with the hydraulic circuit in swing arm energy storage oil cylinder 7 large chambeies, accumulator 1 mesohigh mixed oil and gas is delivered to the large chamber of swing arm energy storage oil cylinder 7, promotes piston rod and stretches out, and swing arm rises.When accumulator 1 is carried 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 at any time the gear groove of spool 4 and the A/F of valve piece 5, to reach accumulator 1 energy, discharges precisely control.
The utility model accumulator Energy release control device, through in the test of hydraulic crawler excavator embarkation, can be accomplished the accurate control to the stored energy of accumulator 1 completely, and can discharge as required.
The foregoing is only preferred embodiment of the present utility model, non-in order to limit the scope of the claims of the present utility model, other use the equivalence of patent spirit of the present utility model to change, and all should all belong to the scope of the claims of the present utility model.
