The invention relates to a cargo boom with a single-cylinder five-section-boom telescopic mechanism and a working method of the cargo boom. The cargo boom comprises a cargo boom unit, a telescopic driving unit, a telescopic boom inhaul cable unit and a telescopic boom inhaul cable unit. The cargo boom unit comprises a first-section arm, a second-section arm, a third-section arm, a fourth-section arm and a fifth-section arm which are sequentially arranged. The extending arm inhaul cable unit comprises a three-section-arm extending arm inhaul cable, a four-section-arm extending arm inhaul cable and a five-section-arm extending arm inhaul cable. A single-cylinder five-section-arm telescopic mechanism is adopted, a steel wire rope winding mode is internally optimized, the space proportion of a steel wire rope in a barrel is reduced, the section of the barrel is saved, on the basis of a traditional single-cylinder five-section-arm telescopic mechanism, a four-section-arm telescopic inhaul cable is omitted and shared with a five-section-arm telescopic inhaul cable, the cost is saved, and compared with a traditional telescopic mode, the telescopic mechanism has the advantages of being simple in structure and convenient to use. The length of a section of extending arm inhaul cable is reduced, that is, the fixing position of the inhaul cable is changed.

    本发明涉及一种具有单缸五节臂伸缩机构的起重臂及其工作方法。该起重臂包括起重臂单元、伸缩驱动单元、伸臂拉索单元和缩臂拉索单元。起重臂单元包括依次设置的一节臂、二节臂、三节臂、四节臂和五节臂。伸臂拉索单元包括三节臂伸臂拉索、四节臂伸臂拉索和五节臂伸臂拉索。本发明采用单缸五节臂伸缩机构,内部优化钢丝绳绕绳方式,减少钢丝绳在筒体里的空间占比,节约筒体截面,在传统单缸五节臂伸缩机构基础上,取消一根四节臂缩臂拉索,与五节臂伸臂拉索共用,节约了成本,并且与传统伸缩方式相比,减少一段伸臂拉索长度,即拉索的固定位置发生了变化。
