Novel scissors type high-altitude operation car

Abstract

The invention discloses a novel scissors type high-altitude operation car. The novel scissors type high-altitude operation car comprises a bottom car body, a middle scissors type vertical folding frame and a top horizontal three-section retractable arm sleeve connection structure which are successively connected; the scissors type vertical folding frame can be unfolded or folded to adjust the height; the horizontal three-section retractable arm sleeve connection structure stretches out of the upper part of the rear end of the car body or draws back from the upper part of the rear end of the car body to adjust the stretching length; a balance weight is mounted in the front of the car body; the car body is steered and driven by the aid of front wheels; and after the front wheels turn left or right, the car body can rotate around a left rear wheel or a right rear wheel. The characteristics of a cantilever crane type high-altitude operation car and a scissors type high-altitude operation car in an existing high-altitude operation car markets are combined, and the novel scissors type high-altitude operation car not only has the property of great stretching length of a working platform of the cantilever crane type high-altitude operation car, but also has the advantage of low price of the scissors type high-altitude operation car, and therefore is suitable for being popularized and used.

Description

technical field [0001] The invention relates to the field of aerial work, in particular to a novel scissor type aerial work vehicle. Background technique [0002] At present, when the aerial work vehicle market requires applications with both variable height and variable overhang length, only boom-type or crank-arm type aerial work vehicles can be used to meet the requirements for overhang length. Such as figure 1 As shown, this kind of high-altitude operation vehicle adopts the telescopic arm and the turning structure of the upper vehicle to meet the requirements of both height and overhang. Due to the need to extend the telescopic oil cylinder and the luffing oil cylinder in the long arm and adopt the upper car slewing support structure, the price is higher. However, due to its large and variable overhang length, it has become the only choice in the market when working at heights when the overhang is required. [0003] Scissor-type aerial work vehicles currently on the ...
