Technical field
The present invention relates to a kind of road sweeper and sweep two air pressure control lifting gears of dish.
Background technology
In recent years, environmental issue is paid close attention to by people always, and the urban road cleaning problems is also paid attention to by people day by day, specially can not satisfy people's demand by the hand sweeping mode, and sweeping machine has obtained violent fast development in recent years as one of major product of environmental sanitation machinery.At present, the dish lifting control of sweeping on the sweeping machine generally is that hydraulic system exists component to cost an arm and a leg by the hydraulic system driving, the defective of oil circuit connection and operating mechanism complexity.Chinese patent ZL 200620049855.4 disclosed a kind of dish self application devices of sweeping; comprise cylinder, pressure regulator valve, connector; one end of connector is connected to be swept on the dish; the other end links to each other with the push rod of cylinder; do not have the gas circuit control of countercylinder to protect, do not have the architectural feature of gas circuit control, and its cylinder mounting means takes up space greatly yet; concerning the road sweeper of compact conformation, realize its function difficulty.
Summary of the invention
At above-mentioned situation, the invention provides a kind of simple and reasonablely, compact, cost is low, uses and two air pressure that easy to operate road sweeper is swept dish are controlled lifting gears.
For achieving the above object, a kind of road sweeper is swept two air pressure control lifting gears of dish, comprise that gasholder connects strainer by tracheae, strainer connects the electromagnetic valve I, two interfaces one tunnel of electromagnetic valve I are through one way valve, one the tunnel through pressure regulator valve be connected the electromagnetic valve II after one way valve is converged by threeway, the electromagnetic valve II connects lift cylinder, one end of lift cylinder is installed on the fixed head of quadric chain, one end is installed on the portable plate of quadric chain, the portable plate of quadric chain installs motor, and the output shaft of motor connects sweeps dish.
In order to realize result optimizing, improve, improve combination property of the present invention, further step is:
Pressure meter is set respectively on described strainer and the pressure regulator valve.
The interface of described electromagnetic valve II and lift cylinder is installed exhaust component respectively.
The present invention adopts gasholder to connect strainer by tracheae, strainer connects the electromagnetic valve I, two interfaces one tunnel of electromagnetic valve I are through one way valve, one the tunnel through pressure regulator valve be connected the electromagnetic valve II after one way valve is converged by threeway, the electromagnetic valve II connects lift cylinder, and an end of lift cylinder is installed on the fixed head of quadric chain, and an end is installed on the portable plate of quadric chain, the portable plate of quadric chain installs motor, and the output shaft of motor connects sweeps dish; On strainer and the pressure regulator valve pressure meter is set; The interface of electromagnetic valve II and lift cylinder is installed the scheme of exhaust component, has overcome existing hydraulic system and has existed component to cost an arm and a leg, and oil circuit connects and the operating mechanism complexity, or the not compact defective of structure.
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 conservation, control characteristics easily.
The present invention is applicable to supporting with the different kinds of roads road-sweeper.
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.

Among the figure: 1, gasholder, 2, strainer, 3, the electromagnetic valve I, 4, pressure regulator valve, 5, one way valve, 6, threeway, 7, the electromagnetic valve II, 8, lift cylinder, 9, quadric chain, 10, motor, 11, sweep dish, 12, pressure meter, 13, exhaust component.
The specific embodiment
By accompanying drawing Fig. 1, shown in Figure 2, a kind of road sweeper is swept two air pressure control lifting gears of dish, comprise that gasholder 1 connects strainer 2 by tracheae, strainer 2 connects electromagnetic valve I 3, two interfaces one tunnel of electromagnetic valve I 3 are through one way valve 5, one the tunnel through pressure regulator valve 4 be connected electromagnetic valve II 7 after one way valve 5 is converged by threeway 6, electromagnetic valve II 7 connects lift cylinder 8, one end of lift cylinder 8 is installed on the fixed head of quadric chain 9, one end is installed on the portable plate of quadric chain 9, and the portable plate of quadric chain 9 installs motor 10, and the output shaft of motor 10 connects sweeps dish 11; On strainer 2 and the pressure regulator valve 4 pressure meter 12 is set respectively; The interface of electromagnetic valve II 7 and lift cylinder 8 is installed exhaust component 13 respectively.
During work, the Y4 end of Y2 end and electromagnetic valve II 7 on the opens solenoid valve I 3, pressurization gas passes through filter 2, electromagnetic valve I 3, pressure regulator valve 4, one way valve 5, threeway 6, electromagnetic valve II 7 to lift cylinder 8 by gasholder 1.When pressurization gas process strainer 2,2 pairs of pressurization gas of strainer 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 quadric chain 9 with sweep dish 11 and produce the power of lifting upwards, the weight that overcomes quadric chain 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 electromagnetic valve II 7 end, pressurization gas passes through filter 2, electromagnetic valve I 3, one way valve 5, threeway 6, electromagnetic valve II 7 to lift cylinder 8 by gasholder 1, lift cylinder 8 is under pressurization gas promotes, rod end stretches out, each hinged place motion of quadric chain 9, lift quadric chain 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 quadric chain 9, motor 10 with sweep in dish 11 the mass motion process, make electromagnetic valve I 3 or electromagnetic valve II 7 reset to interposition by operation, motor 10 and sweep dish 11 arbitrary positions that can stop in the motion process.In this gas circuit work, by regulating the pressurization gas pressure of strainer 2, the power of upwards lifting that can regulate lift cylinder 8.
Close the Y1 end of electromagnetic valve I 3 and the Y4 end of electromagnetic 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 electromagnetic valve II 7, pressurization gas transfers low-pressure gas to, the power of lifting of 8 pairs of quadric chains 9 of lift cylinder descends, lift cylinder 8 is at quadric chain 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 Elements, and the scheme that pneumatic control is changed into hydraulic control also belongs to the scope of protection of the invention.
