Embodiment Construction

[0009] Below in conjunction with accompanying drawing description and specific embodiment, the present invention will be described in further detail:

[0010] see figure 1 , a hybrid arm type aerial work vehicle, comprising a boarding part and a disembarking part, the boarding part includes a turntable 3, a lower luffing hydraulic cylinder 4, an upper luffing hydraulic cylinder 7, a lower main arm 5, an upper main arm 8, Lower telescopic arm 6, upper telescopic arm 9, work platform 10, work platform pedal 11 and work platform leveling mechanism 12. The getting off part comprises the automobile chassis 2, the hydraulic support leg 1 and the driver's cab and the like. The hydraulic outrigger 1 is set on the bottom of the automobile chassis 2, the turntable 3 is placed on the automobile chassis 2, the upper part rotates relative to the lower part, the lower main arm 5 is hinged on the rotary platform 3, and the lower luffing cylinder 4 is responsible for controlling the variable...

Abstract

The invention discloses a mixed arm type overhead working truck. The mixed arm type overhead working truck comprises hydraulic supporting legs, an automobile chassis, a rotary table, a low variable-amplitude hydraulic cylinder, an upper variable-amplitude hydraulic cylinder, a lower main arm, an upper main arm, a lower telescopic arm, an uppper telescopic arm, a working platform, a working platform pedal and a working platform leveling mechanism, wherein the hydraulic supporting legs are arranged on the bottom of the automobile chassis; the rotary table is arranged on the automobile chassis; and the lower main beam is hinged on the rotary table. The mixed arm type overhead working truck is characterized in that the section of the lower telescopic arm is octahedral, and the section of the upper telescopic arm is hexagonal. According to the mixed arm type overhead working truck disclosed by the invention, upper and lower telescopic arms with different sections are adopted, and reinforcing ribs are mounted on the lower telescopic arm and the upper telescopic arm, so that strength, rigidity and stability of the overhead working truck with relatively high operating height (50m-110m) further can be guaranteed, and therefore, the performance of the whole truck is improved. Meanwhile, a weight reducing hole in the lower telescopic arm can reduce dead load of an arm rest of the overheadworking truck, reduces mass of the whole truck, and reduces production and operation cost.

Description

technical field [0001] The invention relates to the field of special vehicles, in particular to a hybrid arm type aerial work vehicle. Background technique [0002] Aerial work vehicle is a commonly used type of special vehicle. It is of great engineering significance for the operation of high-rise basic buildings, fire fighting and rescue, and the protection of people's lives and property. With the development of society, the number and height of high-rise buildings in large and medium-sized cities have increased greatly. This requires the development of aerial work vehicles to high performance. At present, there is a big gap between the technical level of my country's aerial work vehicles and the products of developed countries and regions such as Europe, America and Japan. Ordinary aerial work vehicles are mostly straight-arm aerial work vehicles, and the working height is not high. The strength of the jib and the stability of the vehicle are not advanced either. Co...
