The invention provides a fork telescopic arm and method for automatic leveling of a freight forklift, and relates to the technical field of freight forklifts.The fork telescopic arm comprises a fork frame, a tipping frame, a tipping oil cylinder, a telescopic arm body and a compensation oil cylinder, a large arm at one end of the telescopic arm body is rotationally connected with a forklift body, the tipping frame is rotationally arranged at the telescopic end of the telescopic arm body, and the fork frame is fixed to the tipping frame; the two ends of the tipping oil cylinder are rotationally installed at the telescopic end of the telescopic arm and the tipping frame respectively, the compensation oil cylinder is rotationally installed on a large arm of the telescopic arm and the vehicle body, and oil cavities in cylinder bodies of the tipping oil cylinder and the compensation oil cylinder are communicated in a staggered mode. A shaft body of the compensation oil cylinder extends out and compensates oil liquid in a cylinder body of the compensation oil cylinder to a cavity of the tipping oil cylinder, so that the shaft body of the tipping oil cylinder is shrunk; the fork arm carrier is driven by the tipping oil cylinder to be automatically adjusted to be in a stable state, and an independent detection probe and a signal processing system do not need to be additionally designed, so that the complexity of the processing process is reduced.

    本发明提供一种货运叉车自动调平的货叉伸缩臂及方法,涉及货运叉车技术领域,包括货叉架、倾翻架、倾翻油缸、伸缩臂和补偿油缸,伸缩臂一端的大臂与车体转动相连,倾翻架转动设在伸缩臂的伸缩端,货叉架固定在倾翻架上,倾翻油缸的两端分别转动安装在伸缩臂的伸缩端与倾翻架上,补偿油缸转动安装在伸缩臂大臂与车体上,其中,倾翻油缸与补偿油缸缸体内油液腔体交错连通,当伸缩臂的大臂围绕车体举升,补偿油缸的轴体伸出并将其缸体内的油液补偿至倾翻油缸的腔体,使倾翻油缸的轴体收缩;通过倾翻油缸带动货叉架自行调节至平稳状态,无需额外设计单独的检测探头和信号处理系统,造成处理过程的复杂程度。
