Description
Technical field
The utility model belongs to all hydraulic pressure steering-gear technical field, is specifically related to the all-hydraulic emergency turn system of explosion-proof vehicle under a kind of coal mine.
Background technology
Under coal mine, explosion-proof vehicle application is more and more wider, under coal mine, on explosion-proof vehicle, be provided with hydraulic steering system, when general hydraulic steering system initial steer, turn to heavy, effort very, difficult realization turns to, affect overall performance, and can not realize emergency turn in the situation that vehicle is flame-out, stop working under coal mine once vehicle and other emergencies occur, because vehicle can not emergency turn, thereby can cause unnecessary danger to occur.
Summary of the invention
The utility model is the technical problem that under solution coal mine, explosion-proof vehicle died needs emergency turn, and the all-hydraulic emergency turn system of explosion-proof vehicle under a kind of coal mine is provided.
The technical solution adopted in the utility model is as follows:
The all-hydraulic emergency turn system of explosion-proof vehicle under a kind of coal mine, comprise hydraulic pump, charging device, energy storage equipment, check valve, steering gear and steering cylinder, hydraulic pump is connected with the oil-in of charging device, the oil-out of charging device is connected with check valve, check valve is connected with energy storage equipment and steering gear, and steering gear is connected with steering cylinder again.
Described charging device comprises check valve I, differential pressure pickup, guide's load releasing valve, oil-in, oil-out and oil return opening, described check valve I one end is connected with oil-in and differential pressure pickup respectively, the other end is connected with oil-out and guide's load releasing valve respectively, and the other two ends of guide's load releasing valve are connected with differential pressure pickup and oil return opening respectively.
Described hydraulic pump is quantitative hydraulic pump.
The beneficial effects of the utility model: all-hydraulic emergency turn system of the present utility model is by having designed large flow charging device and large flow energy storage equipment, after vehicle cycling start, charging device is that energy storage equipment starts topping up, pressure reaches after the pressure of energy storage equipment setting, charging device is laid down the pressure oil of hydraulic pump, make energy storage equipment in packing state, at this time, if direction of operating dish, in its loop owing to there being hydraulic oil, turning rate is easier to, solved in flame-out situation can not emergency turn problem, and in normal direction of rotation situation, turn to light, flexibly. the utility model is by having designed large flow charging device and large flow energy storage equipment, meet vehicle and in flame-out situation, realized the requirement of emergency turn, perfect overall performance, has improved the safety and reliability of complete machine, wins the market enough advantage is provided for this vehicle.

Detailed description of the invention
As Fig. 1, shown in 2, the all-hydraulic emergency turn system of explosion-proof vehicle under a kind of coal mine, comprise hydraulic pump 1, charging device 2, energy storage equipment 3, check valve 4, steering gear 5 and steering cylinder 6, described charging device 2 comprises check valve I7, differential pressure pickup 8, guide's load releasing valve 9, oil inlet P 3, oil-out P5 and oil return inlet T 2, described check valve I7 one end is connected with oil inlet P 3 and differential pressure pickup 8 respectively, the other end is connected with oil-out P5 and guide's load releasing valve 9 respectively, check valve I7 is connected with guide's load releasing valve 9 by throttle orifice, the other two ends of guide's load releasing valve 9 are connected with differential pressure pickup 8 and oil return inlet T 2 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-out P5 of charging device 2 is connected with check valve 4, check valve 4 is connected with energy storage equipment 3 and steering gear 5, and steering gear 5 is connected by threeway with two steering cylinders 6 again.
The operation principle of charging device: pressure oil enters charging device from 3 mouthfuls of oil inlet P, arrive oil-out P5 mouth through check valve I7, wherein some is controlled oil and flows to differential pressure pickup 8, through throttle orifice 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-out P5 mouth from 3 mouthfuls of hydraulic oil that flow to of oil inlet P, if the pressure that flows to the control oil in differential pressure pickup 8 reaches the pressure of guide's load releasing valve 9, guide's load releasing valve 9 is opened, pressure oil all flows to fuel tank through differential pressure pickup 8.
The operation principle of all-hydraulic emergency turn system of the present utility model: after vehicle cycling start, hydraulic pump 1 is started working, owing to being constant displacement pump, it is constant that flow keeps 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, hydraulic oil all flows to fuel tank through the differential pressure pickup 8 in charging device 2, energy storage equipment 3 is in packing state, at this time, if direction of operating dish, in its loop owing to there being hydraulic oil, turning rate is easier to, solved in flame-out situation can not emergency turn problem, and in normal direction of rotation situation, turn to light, flexibly.
