Background technique
With the fast development of Chinese economy, the demand of high-altitude operation vehicle is increasing, city and intown road are repaired
Lamp, the place of electric power are more and more.When high-altitude operation vehicle operation occupy ground space it is big, and sometimes in operation need across
The demands such as obstacle-overpass are easy to influence traffic.So the high-altitude operation vehicle of special structure form is needed, when meeting arrival operation ground
Traffic is not influenced not only, while can directly reach operating location across certain obstacle.
There is also following deficiencies for existing high-altitude operation vehicle:
One, current high-altitude operation vehicle is broadly divided into three classes: folding arm, telescopic arm, mixing arm.
Lower arm luffing range of cantilever support is pushed by lower arm amplitude oil cylinder when folding the operation of arm high-altitude operation vehicle, upper arm amplitude oil cylinder pushes away
Dynamic upper arm luffing range of cantilever support, the angle change of Lai Shixian cantilever crane, so that job platform is given rise to certain altitude, with reaching operation
Point.Operation height is determined according to cantilever crane length and change angle, if reach a certain height, needs longer cantilever crane and big change
Argument degree causes full car length longer.Operating efficiency is low simultaneously, and obstacle crossing ability is weak.
Luffing range of cantilever support, simultaneous retractable oil cylinder pushing telescopic arm are pushed by amplitude oil cylinder when telescopic arm high-altitude operation vehicle operation
Movement, reaches operating location for job platform.The operating location for reaching certain altitude, needs telescopic arm extension elongation vertically
The projection in face, so needing cantilever crane length longer if reach a certain height and amplitude.Simultaneous retractable arm overhang is bigger, stretches
