The beneficial effect that the present invention is produced compared to existing technology:
1, make full use of existing source of the gas resource on the automobile, the control road sweeper is swept the lifting action of dish, has saved cost, has simplified control mode.
2, realized sweeping down maneuver before the sweeping ground by lift cylinder, lifted action when sweeping sweeping ground, and the vertical motion when sweeping dish and stopping operation, guaranteed to sweep the dish action and cooperated and sweep the cleaning that dish has been finished road.
3, simple and reasonable, compact, low cost of manufacture.
4, have energy saving, control characteristics easily.
The present invention is applicable to supporting with the different kinds of roads sweeper.
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Description of drawings
Fig. 1 is an erection drawing of the present invention.
Fig. 2 is a gas control schematic diagram of the present invention.
Among the figure: 1, gas holder, 2, filter, 3, the solenoid valve I, 4, pressure regulator valve, 5, one-way valve, 6, threeway, 7, the solenoid valve II, 8, lift cylinder, 9, quadratic crank mechanism, 10, motor, 11, sweep dish, 12, pressure gauge, 13, exhaust component.
Embodiment
By accompanying drawing Fig. 1, shown in Figure 2, a kind of road sweeper is swept two air pressure control lowering or hoisting gears of dish, comprise that gas holder 1 connects filter 2 by tracheae, filter 2 connects solenoid valve I 3, two interfaces one tunnel of solenoid valve I 3 are through one-way valve 5, one the tunnel through pressure regulator valve 4 be connected solenoid valve II 7 after one-way valve 5 is converged by threeway 6, solenoid valve II 7 connects lift cylinder 8, one end of lift cylinder 8 is installed on the fixed plate of quadratic crank mechanism 9, one end is installed on the mobile plate of quadratic crank mechanism 9, and the mobile plate of quadratic crank mechanism 9 installs motor 10, and the output shaft of motor 10 connects sweeps dish 11; On filter 2 and the pressure regulator valve 4 pressure gauge 12 is set respectively; The jointing of solenoid valve II 7 and lift cylinder 8 is installed exhaust component 13 respectively.
During work, the Y4 end of Y2 end and solenoid valve II 7 on the opens solenoid valve I 3, pressurization gas passes through filter 2, solenoid valve I 3, pressure regulator valve 4, one-way valve 5, threeway 6, solenoid valve II 7 to lift cylinder 8 by gas holder 1.When pressurization gas process filter 2,2 pairs of pressurization gas of filter carry out a step-down to be handled, when gas advanced pressure regulator valve 4,4 pairs of pressurization gas of pressure regulator valve carry out the secondary step-down to be handled, low-pressure gas after the secondary step-down is by lift cylinder 8, to quadratic crank mechanism 9 with sweep dish 11 and produce the power of lifting upwards, the weight that overcomes quadratic crank mechanism 9, motor 10 and sweep dish 11, by regulating the gas pressure of pressure regulator valve 7, make lift cylinder 8 stop motions, sweep the dish 11 when sweeping the road just kiss the earth sweep the road.
When the Y4 of the Y1 of opens solenoid valve I 3 and solenoid valve II 7 end, pressurization gas passes through filter 2, solenoid valve I 3, one-way valve 5, threeway 6, solenoid valve II 7 to lift cylinder 8 by gas holder 1, lift cylinder 8 is under pressurization gas promotes, rod end stretches out, each hinged place motion of quadratic crank mechanism 9, lift quadratic crank mechanism 9, motor 10 and sweep dish and 11 lift, reach maximum shape journey, make and sweep dish 11 and stop in highest order until lift cylinder 8.At quadratic crank mechanism 9, motor 10 with sweep in dish 11 the mass motion process, make solenoid valve I 3 or solenoid valve II 7 reset to interposition by operation, motor 10 and sweep dish 11 arbitrary positions that can stop in the movement process.In this gas circuit work, by regulating the pressurization gas pressure of filter 2, the power of upwards lifting that can regulate lift cylinder 8.
Close the Y1 end of solenoid valve I 3 and the Y4 end of solenoid valve II 7, the Y3 end of opens solenoid valve II 7, pressurization gas in the lift cylinder 8 is entered in the atmosphere by exhaust component 13 parts of solenoid valve II 7, pressurization gas transfers low-pressure gas to, the power of lifting of 8 pairs of quadratic crank mechanisms 9 of lift cylinder descends, lift cylinder 8 is at quadratic crank mechanism 9, motor 10 and sweep under dish 11 the weight effect and shrink, and sweeps dish 11 and descends, until the height of reducing to when sweeping dish 11 and sweeping the road; The opening time of the Y3 end of control electromagnetic valve II 7, can control and sweep the dish falling head.
The present invention changes gas-pressure component into similar hydraulic element, and the scheme that pneumatic control is changed into hydraulic control also belongs to the scope of protection of the invention.
