The invention discloses a movable portable lifting device. The device comprises a base; the supporting column is provided with a first rotating shaft; the middle of a beam body of the cross beam is hinged to the supporting column through a horizontal second rotating shaft, and an operation assembly is arranged at one end of the cross beam; the operation assembly comprises an operation rod, a rope disc and a rocker arm limiting piece, the rocker arm limiting piece comprises a vertical rod, a transverse rod and an extension rod, and a hook-shaped component used for keeping the distance between the rope disc and a rocker arm is arranged at the tail end of the extension rod. The device overcomes the problems that an existing lifting device is not suitable for a narrow working site, depends on power of a power source, is inconvenient to steer and the like, achieves vertical and horizontal free rotation of the cross beam by arranging the first rotating shaft in the middle of the supporting column and connecting the cross beam through the second rotating shaft, and is flexible and efficient in operation. The lifting rope can be quickly retracted, the cross beam can be conveniently operated to carry heavy objects, the occupied space is small, operation is convenient and efficient, power supply power is not needed, and heavy object carrying can be completed by one person.
本发明公开了可移动便携起重装置,包括:底座;支柱,其设置第一转轴;横梁,其梁体中部通过水平的第二转轴铰接于支柱上,横梁一端设置有操作组件;操作组件包括操作杆、绳盘、摇臂限位件,摇臂限位件包括竖杆、横杆和延伸杆,延伸杆的末端设置有用于保持绳盘摇臂间距的钩形构件。此装置克服了现有起重装置不适用于狭小工作场地、依赖电源动力、转向不方便等问题,通过在支柱中间设置第一转轴并用第二转轴连接横梁,实现横梁的竖直和水平自由转动,操作灵活高效,通过绳盘摇臂和摇臂限位件间的配合,可以实现快速收起吊绳并顺势操作横梁进行重物搬运,不仅占用空间小,而且操作方便高效,不依赖电源动力,一个人就可以完成重物搬运。
