Problems solved by technology

[0002] Self-propelled aerial work platforms are widely used in shipbuilding, engineering construction, industrial installation, equipment maintenance and other industries. The ground of these workplaces is generally not flat, and there are obstacles such as potholes, slopes and stones. Traditional rigid self-propelled The off-road ability of the base of the type platform is insufficient, and the four-wheel drive is acceptable. If the two-wheel drive is used, it is basically impossible to apply in this kind of place; and if the distance between the base and the ground is too low, the passing ability is poor and it cannot adapt to obstacles If there are many places, if the distance between the base and the ground is too high, the supporting force for the high-altitude platform will not be enough, and it is prone to rollover and cause accidents
[0003] In order to improve the stability of the high-altitude platform and reduce the possibility of rollover, it is necessary to increase the wheelbase, but the passability of the large wheelbase is poor, and there is a maximum wheelbase requirement for driving on the road, so a retractable wheelbase is required. Reduce the wheel base; recently, most of the bases are in the state of stopping, and the lifting device is used to raise the roof to a certain height, so that the wheels are lifted from the ground and then stretched. After the stretch is in place, the car is put down manually. The work efficiency is low and the structure is complicated.

Abstract

The invention discloses a self-propelled platform base, which comprises a base, wherein the base is hinged with a swing bridge through a base spindle; wheels are arranged on the two sides of the swing bridge; extension bridges are arranged on the inner sides of the wheels and in the swing bridge and comprise a left extension bridge and a right extension bridge; the wheels include a left wheel and a right wheel; the left extension bridge is arranged on the inner side of the left wheel and the right extension bridge is arranged on the inner side of the right wheel; and the left and right extension bridges are not in the same line. In the invention, as the extension mechanisms of the left and right wheels are not in the same line, wider extension space is formed on the basis of the same base width, and the extended base is wider and more stable, provides a higher strength for supporting an overhead operation platform and lowers tripling possibility; the extension bridge structure can complete extending wheel distance in a running process; the working efficiency is high; and stability and reliability are ensured.
