Description
Technical Field
The invention relates to the field of aerial work equipment, in particular to a full-electric scissor-type aerial work platform.
Background
The scissor-type aerial work platform is mainly used for aerial work and widely applied to modern production life, and the whole system mainly comprises a lifting system, a walking system, a steering system and a power source system. The conventional power source system is an electro-hydraulic driving system, a motor drives a hydraulic pump to work, and a control valve group is used for realizing the work of a hydraulic oil driving lifting system, a steering system and a walking system. In recent years, a part of the traveling systems of the scissor-type aerial work platforms are driven by motors in sequence, but the lifting systems and the steering systems are still driven by hydraulic methods.
Although the existing hydraulic system for the scissor-type aerial work platform has high power density and strong load impact resistance, the energy utilization rate of the hydraulic system is far lower than that of a pure electric system. With the improvement of the requirement of users on no hydraulic oil leakage risk in data centers, large electronic factories, large shops, museums and other occasions, the existing electro-hydraulic driven scissor-type aerial work platform is difficult to meet the requirements of complete machine on no hydraulic oiling and full electromotion.
The following briefly analyzes the related art disclosed in the prior patent documents, such as: the Chinese patent with the application number of 201620379808.X discloses an intelligent leveling electric aerial work platform for a building, wherein although the provided electric driving lifting mechanism can solve the problems of hydraulic oil leakage and low energy utilization rate caused by a hydraulic lifting system, the whole system can only be adapted to an arm type non-self-walking aerial work platform, and the multi-system electromotion problem of a scissor type aerial work platform can not be solved. Although chinese patents with application numbers CN201720489203.0 and CN201710878796.4 propose a scheme of using a motor in a driving system, the whole system still adopts a hydraulic system as a power source, and the drawbacks of the hydraulic system are not fundamentally solved. The chinese patent with application number CN201822063258.2, the proposed hybrid power driving system cannot completely realize zero emission of the whole machine, and the volume of the hybrid power system cannot adapt to the limited installation space of the scissor-type aerial work platform. Although the chinese patent with application number CN201911004534.0 optimizes the driving structure of the hydraulic system, it still cannot completely compensate for the short plates brought by the hydraulic system.
