Abstract

The application discloses a self-propelled mechanism of an electric scissors maintenance operation device, which includes a bogie assembly, a wheel assembly, a drive assembly, an electric control system and a hydraulic system, and the drive assembly is connected to the wheel assembly and the bogie assembly. It has the following advantages: adopting electro-hydraulic integrated control, it can realize four self-propelled functions such as straight running, diagonal driving, lateral driving and in-situ steering.

Description

technical field [0001] The invention relates to a self-propelled mechanism of an electric scissor maintenance operation device and a self-propelled mode control method thereof, belonging to the technical field of mechanical equipment. Background technique [0002] Existing aerial work platforms generally include a chassis, a walking device, a lifting device and a working platform. The upper end of the lifting device is connected to the working platform, the lower end is connected to the chassis, and the walking device is installed on the chassis. Mast type lifting device or sleeve type lifting device, traveling device can be wheel type or crawler type traveling device. The self-propelled scissor-type aerial work platform is one of many aerial work platforms. Its lifting device is a scissor-type lifting device. The walking device realizes self-propelling through the walking hydraulic system. The walking hydraulic system is generally composed of a pump and an electromagnetic r...
