Abstract
The utility model provides a washing and sweeping vehicle's back door sealing strip protector mainly includes: hydraulic pump, tribit cross magenetic exchange valve, check valve, your bi -pass magenetic exchange valve, energy storage ware, hydraulic cylinder, overflow valve, time relay, its characterized in that: the energy storage ware connects in parallel through your bi -pass magenetic exchange valve and check valve does not have the pole chamber at hydraulic cylinder, and tribit cross magenetic exchange valve oil inlet does not have the pole chamber with hydraulic cylinder respectively and links to each other with the hydraulic pump, and the oil return opening has the pole chamber to link to each other with the oil tank with hydraulic cylinder respectively, and the overflow valve is connected in the hydraulic pump export, and time relay and your bi -pass magenetic exchange valve series connection are in control circuit. Time relay comprises coil and switch. The utility model discloses can also be applied to on the sanitation garbage truck. The utility model has the advantages of good, the reduce cost of life, leakproofness rational in infrastructure, as to improve the sealing strip.
Description
technical field:
The utility model belongs to environmental sanitation refuse vehicle technical field, particularly relates to a kind of back door sealing strip protective equipment of sweeper.
background technique:
Along with the continuous expansion of urban construction scale, Optimizing City environment is also more and more paid attention to by country.The rubbish kind of current urban road presents diversified trend, and for building good living environment to everybody, environmental sanitation department generally adopts sweeper to clean road, not only increases working efficiency, also reduces cost of labor.But sweeper in the course of the work, the road conditions being coated with corrosivity sewage can be run into; And sweeper these sewage inspiration railway carriages, can not poured out completely, sewage can contact back door sealing strip, even some corrosive rubbish also can stick on Stamping Steel Ribbon, and then the corrosion of aggravation to Stamping Steel Ribbon, cause Stamping Steel Ribbon resistance to pressure not high, back door sealing imprecision.User is reflected also than stronger back door sealing protection this situation not good enough.In order to address this problem, we have devised a kind of back door sealing strip protective equipment of sweeper.
summary of the invention:
The purpose of this utility model is to solve the problem, and the back door sealing strip protective equipment of a kind of sweeper provided.
It is implement like this that the utility model solves the technological scheme that its technical problem adopts: a kind of back door sealing strip protective equipment of sweeper, mainly comprise: oil hydraulic pump, three-position four-way electromagnetic directional valve, one-way valve, bi-bit bi-pass solenoid directional control valve, accumulator, hydraulic jack, relief valve, the time relay, it is characterized in that: accumulator is connected in parallel on hydraulic jack rodless cavity by bi-bit bi-pass solenoid directional control valve and one-way valve, three-position four-way electromagnetic directional valve filler opening is connected with oil hydraulic pump with hydraulic jack rodless cavity respectively, return opening is connected with fuel tank with hydraulic jack rod chamber respectively, relief valve is connected to hydraulic pump outlet, the time relay and bi-bit bi-pass solenoid directional control valve are connected in control circuit.
The described time relay is made up of coil and switch.
The utility model can also be applied on environmental sanitation refuse vehicle.
The utility model has working life, good airproof performance rational in infrastructure, to improve Stamping Steel Ribbon, the advantage such as to reduce costs.
accompanying drawing illustrates:
Fig. 1 is hydraulic schematic diagram of the present utility model.
Fig. 2 is the wiring diagram of the time relay of the present utility model.
Back door of the present utility model, Fig. 3 position schematic diagram.
In figure: 1. oil hydraulic pump, 2. three-position four-way electromagnetic directional valve, 3. one-way valve, 4. accumulator, 5. bi-bit bi-pass solenoid directional control valve, 6. hydraulic jack, 7. relief valve, the 8. time relay, 9. back door, 10. back door sealing strip, 11. casings
embodiment:
As Fig. 1, Fig. 2, shown in Fig. 3: a kind of back door sealing strip protective equipment of sweeper, mainly comprise: oil hydraulic pump 1, three-position four-way electromagnetic directional valve 2, one-way valve 3, bi-bit bi-pass solenoid directional control valve 4, accumulator 5, hydraulic jack 6, relief valve 7, the time relay 8, it is characterized in that: accumulator 5 is connected in parallel on hydraulic jack 6 rodless cavity by bi-bit bi-pass solenoid directional control valve 4 and one-way valve 3, three-position four-way electromagnetic directional valve 2 filler opening is connected with oil hydraulic pump 1 with hydraulic jack 6 rodless cavity respectively, return opening is connected with fuel tank with hydraulic jack 6 rod chamber respectively, relief valve 7 is connected to oil hydraulic pump 1 and exports, the time relay 8 and bi-bit bi-pass solenoid directional control valve 3 are connected in control circuit.
The described time relay forms oscillation information output circuit by coil, output switch information.
The utility model can also be applied on environmental sanitation refuse vehicle, prevents casing from leaking.
Embodiment: when sweeper work is complete discharge sewage after, when partial corrosion sewage or corrosive garbage adhesion to be attached on back door sealing strip 10, the while of three-position four-way electromagnetic directional valve 2Y and 3Y after dead electricity, selector valve is in meta, relief valve is opened, oil hydraulic pump off-load, the time relay 8 starts timing simultaneously, after reaching set time, the time relay 8 moving together contact starts to close, bi-bit bi-pass solenoid directional control valve 1Y obtains electric, pressure oil in accumulator 5 enters hydraulic jack 6 rodless cavity, realize back door 9 part to open, namely back door sealing strip 10 and casing 11 is avoided to extrude for a long time or the breakage because of corrosion in water.
