The pulley principle lifting rod comprises a first-stage pipe joint, a middle pipe joint, a last-stage pipe joint and a steel wire rope, the last-stage pipe joint is arranged in the middle pipe joint, a middle pulley mounting seat is arranged at one end of the bottom of the middle pipe joint, and middle inner pulleys are arranged on the two sides of the bottom of the middle pulley mounting seat; the steel wire rope is controlled to be wound and unwound, the lifting rod is controlled to ascend and descend, the structure is simple and compact, carbon fiber materials of the pipe joints are matched, the steel wire rope is controlled to be wound and unwound, the steel wire rope is controlled to be wound and unwound, the lifting rod is controlled to ascend and descend, and the steel wire rope and the steel wire rope are controlled to be wound and unwound. The self weight of the lifting rod is greatly reduced, more middle pipe joints can be installed, the lifting height of the lifting rod has a wider application range, meanwhile, through cooperation of the steel wire rope and the pulley block, section-by-section lifting is achieved when the lifting rod ascends and descends, and the lifting process is more stable and reliable.

    本发明公开了一种滑轮原理升降杆,包括:首级管节、中间管节、末级管节和钢丝绳,所述中间管节内部设有末级管节,所述中间管节底部一端设有中间滑轮安装座,所述中间滑轮安装座底部两侧设有中间内滑轮,所述末级管节底部一端设有末级滑轮安装座,所述末级滑轮安装座底部两侧设有末级内滑轮,所述首级管节顶部设有首级滑轮上盖,本发明通过控制钢丝绳的收卷和放卷,控制升降杆的升降,结构简单紧凑,配合管节的碳纤维材质,大幅度降低了升降杆的自重,能够安装更多的中间管节,使得升降杆的升降高度具有更广的适用范围,同时通过钢丝绳与滑轮组的配合,使得在升降杆升降时实现逐节升降,升降过程更加平稳可靠。
