Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
Embodiment one:
Present embodiments provide a kind of suction nozzle lifting gear of dust collecting and cleaning vehicles, the structure of the suction nozzle lifting gear of these dust collecting and cleaning vehicles as shown in Figures 1 to 6, it comprises lift control switch 1, hydraulic power unit 2, hoisting mechanism 3, suction nozzle assembly 4 and battery 7, lift control switch 1 is electrically connected with hydraulic power unit 2, hydraulic power unit 2 is connected with suction nozzle assembly 4 with hoisting mechanism 3 by oil pipe, lift control switch 1 sends input signal to hydraulic power unit 2, and hydraulic power unit 2 drives suction nozzle assembly 4 to rise or decline by hoisting mechanism 3.The present invention possesses the advantage that hydraulicdriven stationarity is good, noise is little, also there is hydraulicdriven self-locking pressure large, the features such as motion credibility is good, handiness simultaneously, the good advantage playing hydraulic system, evaded its shortcoming, the application of automatically controlled combination makes it have more maneuvering performance easily.
Concrete, see Fig. 1, hydraulic power unit 1 comprises drive motors 11, gear pump 12 and solenoid operated directional valve (not shown).Battery 7 is connected with the power input shaft of drive motors 11.The power output shaft of drive motors 11 connects gear pump 12, gear pump 12 is connected with solenoid operated directional valve and fuel tank respectively by oil pipe, solenoid operated directional valve is connected with two lift cylinders 31 of following hoisting mechanism 3 by oil pipe, for compression or elongation two lift cylinders 31, realize rising or the decline of suction nozzle assembly 4.
As shown in Figure 2 and Figure 5, hoisting mechanism 3 comprises two lift cylinders 31 and two lifting connecting rods 32 that are symmetrical set on dust collecting and cleaning vehicles support 5.The two ends of the rod chamber of two lift cylinders 31 are all connected with the solenoid operated directional valve of oil pipe threeway 6 with hydraulic power unit 1 by oil pipe.The cylinder piston rod of each lift cylinder 31 connects the middle part that promotes connecting rod 32, and one end and the suction nozzle assembly 4 of each lifting connecting rod 32 are hinged, and its other end is hinged with dust collecting and cleaning vehicles support 5 by promoting connecting rod fixed support 321.Hoisting mechanism 3 can be elevated suction nozzle assembly 4, so that suction nozzle absorbs rubbish when operation, lifts when off working state, in order to avoid be damaged.
See Fig. 2, Fig. 3 and Fig. 6, suction nozzle assembly 4 comprises suction nozzle, suction nozzle mounting bracket 41, the front universal caster wheel 42 be arranged on suction nozzle mounting bracket 41, rear universal caster wheel 43 and suction pipe 44.Suction nozzle is connected with suction pipe 44, for absorbing rubbish and sewage.One end of suction nozzle is connected with suction nozzle baffle plate 45, for improving the vacuum in suction nozzle, improves the air velocity at suction nozzle place.Suction nozzle baffle plate 45 preferably has the rubber tile of better abrasion resistance.Suction nozzle mounting bracket 41 is connected with the lifting connecting rod 32 of hoisting mechanism 3 by promoting limiting plate 33.
See Fig. 4, the elevating movement process of suction nozzle assembly 4 is specific as follows: the raise button of pressing lift control switch 1, the drive motors 11 of hydraulic power unit 2 works, by the outwards fuel feeding of the gear pump 12 in hydraulic power unit 2, the outside fuel feeding of the solenoid operated directional valve of hydraulic oil on hydraulic power unit 2 enters oil return pipe, again in the rod chamber that oil pipe threeway 6 flows into two lift cylinders 31, two cylinder piston rods are then compressed, two promote connecting rod 32 and rise, thus pull suction nozzle assembly 4 to rise.Because of suction nozzle assembly 4 center of gravity rearward, so promote time, front universal caster wheel 42 first can depart from ground, rear universal caster wheel 43 also in ground surface, until rise to when the lifting limiting plate 33 on suction nozzle assembly 4 contacts with dust collecting and cleaning vehicles support 5; Cylinder piston rod continues to shrink afterwards, suction nozzle assembly 4 can to promote limiting plate 33 with dust collecting and cleaning vehicles support 5 contact position for overturn point, and cause the head of suction nozzle assembly 4 slightly to fall, afterbody rises, namely after, universal caster wheel 43 rises, thus reaches suction nozzle assembly 4 and depart from completely with ground.So, lift suction nozzle assembly when off working state, both prevented the damage of dust collecting and cleaning vehicles, in turn ensure that dust collecting and cleaning vehicles fast running.Otherwise suction nozzle assembly 4 declines and carries out the work of suction rubbish.
The present invention converts by gear pump the torque that hydraulic power unit drive motors exports to hydraulic energy, enters lift cylinder, then convert mechanical energy to by oil circuit, by the falling-rising of the flexible drive hoisting mechanism of lift cylinder, thus realizes the lifting of suction nozzle assembly.
Hoisting mechanism in the present invention is not limited to above-mentioned situation, can also be the form of structure such as other linkages, and the transmission that can realize moving makes suction nozzle assembly carry out being elevated.
Below know-why of the present invention is described in conjunction with specific embodiments.These describe just in order to explain principle of the present invention, and can not be interpreted as limiting the scope of the invention by any way.Based on explaining herein, those skilled in the art do not need to pay performing creative labour can associate other detailed description of the invention of the present invention, and these modes all will fall within scope.
