Below in conjunction with accompanying drawing, a kind of underground carry scraper throttle of the utility model remote control hydraulic system is described further.
Accompanying drawing explanation
Fig. 1 is a kind of underground carry scraper throttle of the utility model remote control hydraulic system hydraulic schematic diagram.
Embodiment
As shown in Figure 1, a kind of underground carry scraper throttle of the utility model remote control hydraulic system, comprising: fuel tank, torque-converters pressure regulator valve 1,3-position-3-way foot valve 3, throttle cylinder 5, two-position three way remote-controlled valve 4, gear box oil drain pan 2;
The filler opening of torque-converters pressure regulator valve 1 is connected with fuel tank, and oil outlet is connected with the filler opening of two-position three way remote-controlled valve 4 with the filler opening of 3-position-3-way foot valve 3 simultaneously; The oil outlet of 3-position-3-way foot valve 3 is connected with the return opening of two-position three way remote-controlled valve 4; The oil outlet of two-position three way remote-controlled valve 4 is connected with the left cylinder room of throttle cylinder 5; The return opening of 3-position-3-way foot valve 3 is connected with gear box oil drain pan 2, and gear box oil drain pan 2 oil outlet is connected with fuel tank.
Only by the telecontrol to two-position three way remote-controlled valve 4 in the utility model, the throttle cylinder 5 of underground carry scraper can complete following action:
When two-position three way remote-controlled valve 4 receives control signal, the spool of two-position three way remote-controlled valve 4 moves down, upper connection, and the pressure oil that and then torque-converters pressure regulator valve 1 provides enters the left cylinder of executive component throttle cylinder 5, the piston of throttle cylinder 5 moves right, and the throttle of underground carry scraper increases.The distance that wherein spool of two-position three way remote-controlled valve 4 moves down can be controlled by remote control unit, when spool moves down apart from time less, the valve port being communicated with two-position three way remote-controlled valve 4 filler opening and oil outlet is just less, the pressure oil flow entering the left cylinder of throttle cylinder is also just less, and the throttle of corresponding underground carry scraper is also just less.When spool moves down apart from time larger, the valve port being communicated with two-position three way remote-controlled valve 4 filler opening and oil outlet is just comparatively large, and enter the pressure oil flow of the left cylinder of throttle cylinder also just comparatively greatly, the throttle of corresponding underground carry scraper is also just larger.
When the control of two-dimentional threeway remote-controlled valve no longer suspension control signal, the spool of two-position three way remote-controlled valve 4 moves up, the next connection, and then the hydraulic oil in the left cylinder of throttle cylinder is back to fuel tank through two-position three way remote-controlled valve 4,3-position-3-way foot valve 3, gear box oil drain pan 2 successively, until the hydraulic oil in throttle cylinder 5 is gradually reduced to minimum flow, now underground carry scraper throttle reaches minimum.
Control only by the trampling of 3-position-3-way foot valve 3, the throttle cylinder 5 of underground carry scraper can complete following action:
When by 3-position-3-way foot valve 3 trampling to minimum point time, the spool of 3-position-3-way foot valve 3 moves to least significant end, now the filler opening of two-position three way foot valve is communicated with oil outlet, the left cylinder that the hydraulic oil that torque-converters pressure regulator valve 1 provides passes 3-position-3-way foot valve 3 successively, two-position three way remote-controlled valve 4 enters throttle cylinder 5, along with the increase of the left cylinder filling amount of throttle cylinder, the throttle of underground carry scraper becomes large.
When by 3-position-3-way foot valve 3 trampling to intermediate point time, the spool of 3-position-3-way foot valve 3 moves to neutral position, now each hydraulic fluid port of 3-position-3-way foot valve 3 is not communicated with mutually, and the hydraulic pressure oil mass in throttle cylinder 5 is constant, and the throttle size of underground carry scraper is also invariable.
When not carrying out trampling to 3-position-3-way foot valve 3, the spool of 3-position-3-way foot valve 3 moves to top, now the return opening of two-position three way foot valve is communicated with oil outlet, hydraulic oil in the left cylinder of throttle cylinder is back to fuel tank through two-position three way remote-controlled valve 4,3-position-3-way foot valve 3, gear box oil drain pan 2 successively, until the hydraulic oil in throttle cylinder 5 is gradually reduced to minimum flow, now underground carry scraper throttle reaches minimum.
A kind of underground carry scraper of the utility model throttle remote control hydraulic system adds throttle cylinder telechirics on the basis of existing underground carry scraper.Two-position three way remote-controlled valve 4 realizes the break-make of oil circuit by accepting remote signal, and then realizes the control to throttle cylinder 5.It can thus be appreciated that, use under severe conditions and comprise underground carry scraper of the present utility model, only need long-range control, the change of underground carry scraper throttle can be realized, eliminate the life threat of environment to staff.
Above-described embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
