Abstract
The utility model discloses a leveling mechanism of a high-altitude work vehicle. The leveling mechanism is composed of a rotary table, a lower arm, a first connecting frame rod, a middle arm, a second connecting frame rod, an upper arm, a first connecting device, a second connecting device and a work platform which are connected through hinge chains to form three parallelogram structures, so that the work platform is always parallel with the ground. The leveling mechanism is simple in structure, slows down shaking of the work platform during work, and provides safe guarantee for operators.
Description
Technical field
The utility model relates to aerial platform workplatform levelling gear, relates to a kind of levelling gear of folding arm aerial platform in particular.
Background technology
Along with China's constant development of economy, Infrastructure is constantly perfect, and the application of aerial platform more and more widely.Aerial platform is in the lifting process, no matter where save arm and swing around hinge, its arm swing angle can cause that all platform tilts with equal angular, therefore, require levelling gear to adjust in real time the angle of inclination of platform, make platform be in the safe condition of requirement.The mode of the dependence oil cylinder leveling that existing aerial platform levelling gear has, but its complex structure cost is higher, is difficult to realize extensive utilization.
Summary of the invention
The purpose of this utility model provides a kind of aerial platform levelling gear, its simple in structure, good balance effect.
Aerial platform levelling gear described in the utility model, comprise turntable, underarm, first side link, middle arm, second side link, upper arm, first connecting device, second connecting device and workplatform, one end of described underarm is connected by first hinge with turntable, the other end of underarm, one end of middle arm is connected by second hinge with first connecting device, the other end of middle arm, one end of upper arm is connected by the 3rd hinge with second connecting device, one end of first side link is connected by the 4th hinge with turntable, the other end is connected by the 5th hinge with first connecting device, one end of second side link is connected by the 6th hinge with first connecting device, the other end of second side link is connected by the 7th hinge with second connecting device, one end of the 3rd side link is connected by the 8th hinge with second connecting device, and the other end of the 3rd side link is connected with the tenth hinge by the 9th hinge with workplatform respectively with the other end of upper arm; The AnchorPoint of the AnchorPoint of the AnchorPoint of first hinge, second hinge, the AnchorPoint of the 5th hinge and four hinges constitutes parallelogram; The AnchorPoint of the AnchorPoint of second hinge, triple hinged AnchorPoint, the 7th hinge and the AnchorPoint of the 6th hinge constitute parallelogram; The AnchorPoint of the AnchorPoint of triple hinged AnchorPoint, the tenth hinge, the AnchorPoint of the 9th hinge and the 8th hinge constitutes parallelogram.
Aerial platform levelling gear described in the utility model, it is simple in structure, by parallelogram principle, guaranteed well workplatform all the time with the ground keeping parallelism, slowed down shaking of workplatform in the working process, for operating personal provides safe guarantee.

Fig. 2 is the structural representation of the utility model amplitude peak operating mode;
Fig. 3 is the structural representation of the utility model maximum height operating mode.
The specific embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by coming by reference to the accompanying drawings.
As Fig. 1, Fig. 2 and shown in Figure 3, this aerial platform levelling gear, comprise turntable 1, underarm 2, first side link 3, middle arm 4, second side link 5, upper arm 6, first connecting device 7, second connecting device 8, the 3rd pipe link 9 and workplatform 10, one end of described underarm 2 is connected by first hinge with turntable 1, the other end of underarm 2, one end of middle arm 4 is connected by second hinge with first connecting device 7, the other end of middle arm 4, one end of upper arm 6 is connected by the 3rd hinge with second connecting device 8, one end of first side link 3 is connected by the 4th hinge with turntable 1, the other end is connected by the 5th hinge with first connecting device 7, one end of second side link 5 is connected by the 6th hinge with first connecting device 7, the other end of second side link 5 is connected by the 7th hinge with second connecting device 8, one end of the 3rd side link 9 is connected by the 8th hinge with second connecting device 8, and the other end of the 3rd side link 9 is connected with the tenth hinge by the 9th hinge with workplatform 10 respectively with the other end of upper arm 6; The AnchorPoint A of the AnchorPoint O of first hinge, the AnchorPoint A of second hinge, the 5th hinge
1AnchorPoint O with four hinges
1Constitute parallelogram; The AnchorPoint B of the AnchorPoint A of second hinge, triple hinged AnchorPoint B, the 7th hinge
1AnchorPoint A with the 6th hinge
2Constitute parallelogram; The AnchorPoint C of triple hinged AnchorPoint B, the tenth hinge, the AnchorPoint C of the 9th hinge
1AnchorPoint B with the 8th hinge
2Constitute parallelogram.
Principle of work:
Because the AnchorPoint of above-mentioned hinge has been formed three parallelogram, i.e. OO as can be known
1∥ AA
1, AA
2∥ BB
1, BB
2∥ CC
1Because OO
1Constant with the angle that horizon keeps, by parallel-crank mechanism motion characteristics AA as can be known
1Constant with the angle that horizon keeps, because AA
