Description
Technical field
The invention belongs to all hydraulic pressure steering-gear technical field, be specifically related to the all-hydraulic emergency turn system of a kind of underground coal mine explosion-proof vehicle.
Background technology
The application of underground coal mine explosion-proof vehicle is more and more wider, underground coal mine explosion-proof vehicle is provided with hydrostatic steering system, turn to during general hydrostatic steering system initial steer heavy, require great effort very much, not easily realize turning to, affect overall performance, and can not emergency turn be realized when vehicle is flame-out, to stop working at underground coal mine once vehicle and other emergency situations occur, because vehicle can not emergency turn, thus unnecessary danger can be caused to occur.
Summary of the invention
The present invention solves the underground coal mine explosion-proof vehicle flame-out technical matters needing emergency turn suddenly, provides the all-hydraulic emergency turn system of a kind of underground coal mine explosion-proof vehicle.
The technical solution used in the present invention is as follows:
The all-hydraulic emergency turn system of a kind of underground coal mine explosion-proof vehicle, comprise Hydraulic Pump, charging device, energy storage equipment, check valve, deflector and steering cylinder, Hydraulic Pump is connected with the oil inlet of charging device, the oil outlet of charging device is connected with check valve, check valve is connected with deflector with energy storage equipment, and deflector is connected with steering cylinder again.
Described charging device comprises check valve I, differential pressure transducer, guide's load releasing valve, oil inlet, oil outlet and return opening, described check valve I one end is connected with differential pressure transducer with oil inlet respectively, the other end is connected with guide's load releasing valve with oil outlet respectively, and the other two ends of guide's load releasing valve are connected with return opening with differential pressure transducer respectively.
Described Hydraulic Pump is quantitative hydraulic pump.
Beneficial effect of the present invention: all-hydraulic emergency turn system of the present invention is by devising large discharge charging device and large discharge energy storage equipment, after vehicle cycling start, charging device is that energy storage equipment starts topping up, after pressure reaches the pressure of energy storage equipment setting, charging device lays down the pressure oil of Hydraulic Pump, energy storage equipment is made to be in packing state, at this time, if direction of operating dish, owing to there is high pressure oil in its loop, turning rate is easier to, solving under misfiring condition can not the problem of emergency turn, and turns to light, flexible in normal direction of rotation situation.The present invention is by devising large discharge charging device and large discharge energy storage equipment, meet the requirement that vehicle realizes emergency turn under misfiring condition, perfect overall performance, improve the safety and reliability of complete machine, winning the market for this vehicle provides enough advantage.

Detailed description of the invention
As Fig. 1, shown in 2, the all-hydraulic emergency turn system of a kind of underground coal mine explosion-proof vehicle, comprise Hydraulic Pump 1, charging device 2, energy storage equipment 3, check valve 4, deflector 5 and steering cylinder 6, described charging device 2 comprises check valve I7, differential pressure transducer 8, guide's load releasing valve 9, oil inlet P 3, oil outlet P5 and oil return inlet T 2, described check valve I7 one end is connected with differential pressure transducer 8 with oil inlet P 3 respectively, the other end is connected with guide's load releasing valve 9 with oil outlet P5 respectively, check valve I7 is connected with guide's load releasing valve 9 by cutoff port, the other two ends of guide's load releasing valve 9 are connected with oil return inlet T 2 with differential pressure transducer 8 respectively, described Hydraulic Pump 1 is quantitative hydraulic pump, one end of Hydraulic Pump 1 is connected with oil cylinder, the other end is connected with the oil inlet P 3 of charging device 2, the oil outlet P5 of charging device 2 is connected with check valve 4, check valve 4 is connected with deflector 5 with energy storage equipment 3, and deflector 5 is connected by threeway with two steering cylinders 6 again.
The principle of work of charging device: pressure oil enters charging device from oil inlet P 3 mouthfuls, oil outlet P5 mouth is arrived through check valve I7, wherein some controls oil and flows to differential pressure transducer 8, through cutoff port wherein to spring cavity, if the pressure of this control oil is less than the pressure of guide's load releasing valve 9, guide's load releasing valve 9 is closed, all flow out from oil outlet P5 mouth from oil inlet P 3 mouthfuls of hydraulic oil flow to, if the pressure flowing to the control oil in differential pressure transducer 8 reaches the pressure of guide's load releasing valve 9, then guide's load releasing valve 9 is opened, pressure oil all flows to fuel tank through differential pressure transducer 8.
The principle of work of all-hydraulic emergency turn system of the present invention: after vehicle cycling start, Hydraulic Pump 1 is started working, owing to being fix-displacement pump, flow keeps constant always, hydraulic oil is through charging device 2, check valve 4 starts topping up to energy storage equipment 3, when pressure arrives certain value, guide's load releasing valve 9 in charging device 2 starts drain charge, the differential pressure transducer 8 of hydraulic oil all in charging device 2 flows to fuel tank, energy storage equipment 3 is in packing state, at this time, if direction of operating dish, owing to there is high pressure oil in its loop, turning rate is easier to, solving under misfiring condition can not the problem of emergency turn, and turn to light in normal direction of rotation situation, flexibly.
