Background technology
Industrialized construction makes urban population and vehicle increase year by year, people, car road traffic produce very big contradiction, guardrail isolation has all been set up in nearly all road crowded places, and municipal highway central authorities guardrail can guide the sight line of driver, runs off road with anti-vehicle and causes vehicle accident.Isolation guardrail is through exposing to the sun and rain, and external dust is more, have impact on the neat and artistic of the appearance of a street.The cleaning of municipal highway central authorities guardrail, not only for the clean and tidy appearance of the city, and can extend service life of guardrail, so that guardrail is carried out routine cleaning.The labor intensity of manual cleaning guardrail is big, and cleaning efficiency is low, about can only clean about 600 meters for each person every day.Daytime, vehicle flowrate was very big, and manual cleaning guardrail is dangerous and affects traffic, is typically in cleaning when vehicle flowrate is relatively small evening, and often has the accident occurring car to hit sanitationman when clean in the evening.Vehicular vehicle for cleaning safeguard railing solves this problem well, and slew gear is a vitals of vehicular vehicle for cleaning safeguard railing, but normally used slew gear exists problems such as designing unreasonable, structure complexity, work process instability.
Summary of the invention
It is an object of the invention to overcome above-mentioned deficiency of the prior art, it is provided that a kind of gear-wheel gear-ring driven type slew gear, it is reasonable in design, simple and practical, M R is convenient, and work process is without rigid shock, speed of gyration is stable, and long service life is applied widely.
For achieving the above object, the technical solution used in the present invention is: a kind of gear-wheel gear-ring driven type slew gear, including the base playing fixed supporting role with for providing the hydraulic motor of driving force, it is characterised in that: also include engaging each other the gyration gear ring constituting gear-wheel gear-ring transmission and swiveling gear；In the middle part of described base, upside is installed with described gyration gear ring, described base is positioned on the upside of described gyration gear ring and is rotatablely equipped with rotatable platform, it is installed with bearing on the upside of described rotatable platform, described bearing is installed with described hydraulic motor, the power output shaft end of described hydraulic motor is fixing with the gear shaft upper end being rotatably installed on described rotatable platform to be connected, it is provided with the bearing for reducing frictional force between described gear shaft and described rotatable platform, described gear shaft is installed with the swiveling gear being meshed with described gyration gear ring.
Above-mentioned gear-wheel gear-ring driven type slew gear, it is characterised in that: described gyration gear ring is welded or is fixedly mounted on described base by multiple bolts.
Above-mentioned gear-wheel gear-ring driven type slew gear, it is characterised in that: described bearing is welded or is fixedly mounted on described rotatable platform by multiple screws.
Above-mentioned gear-wheel gear-ring driven type slew gear, it is characterised in that: described hydraulic motor power output shaft end is connected by shaft coupling is fixing with described gear shaft upper end.
Above-mentioned gear-wheel gear-ring driven type slew gear, it is characterised in that: described bearing is thrust bearing.
The present invention compared with prior art has the advantage that
(1) design of this gear-wheel gear-ring driven type slew gear is very reasonable, and simple and practical, gyration gear ring is fixedly mounted on base, and M R is very convenient.
(2) this gear-wheel gear-ring driven type slew gear passes through pitch wheel and gear ring transmission, and without rigid shock in work process, speed of gyration is stable, long service life.
(3) this gear-wheel gear-ring driven type slew gear is applicable not only to vehicular vehicle for cleaning safeguard railing, applies also for other engineering machinery such as on-vehicle hedge clipping machine, and the scope of application is very wide.
Below by drawings and Examples, the present invention is described in further detail.
