Problems solved by technology

[0002] At present, most AGVs of mobile carrying equipment require the function of platform lifting. However, the elevator driving mode adopted by the lifting platform of most mobile carrying equipment AGVs in China cannot meet the increasingly demanding requirements due to the power limitation of the electric drive elevator and the limited weight of the lifting load. The demand for the development of heavy-duty mobile lifting equipment (heavy-load mobile lifting AGV); however

Abstract

The invention relates to a multi-two-stage-cylinder hydraulic synchronous control system, and belongs to the technical field of hydraulic transmission and control. According to the multi-cylinder synchronous hydraulic system suitable for a vertical installation hydraulic cylinder of a movable heavy-load AGV, not only can the requirement of a large load be met, but also the mechanical structure canbe simplified and the requirement of a large stroke can be met, and meanwhile, the problem of meeting the control precision of the multi-cylinder synchronous lifting hydraulic system is solved.

Description

technical field [0001] The invention belongs to the technical field of hydraulic transmission and control, and in particular relates to a multi-two-stage cylinder hydraulic synchronous control system. Background technique [0002] At present, most AGVs of mobile carrying equipment require the function of platform lifting. However, the elevator driving mode adopted by the lifting platform of most mobile carrying equipment AGVs in China cannot meet the increasingly demanding requirements due to the power limitation of the electric drive elevator and the limited weight of the lifting load. The demand for the development of heavy-duty mobile lifting equipment (heavy-load mobile lifting AGV); however, some mobile equipment AGVs currently use hydraulic lifting platforms, but hydraulic lifting platforms require high synchronization performance, so some hydraulic lifting platforms use mechanical synchronization. Advanced lifting platforms, such as scissor lifting platforms, not only...
