The invention discloses a universal pulley device easy to assemble and disassemble on a steel structure column. The universal pulley device comprises a pulley body, a pulley body mounting seat, an anti-off-line device and an on-column mounting seat, the pulley body is a cylinder, and two ends of the pulley body are mounted on the pulley body mounting seats through wheel shafts; the anti-off-line device comprises a baffle ring, a baffle ring supporting frame and an elastic limiting assembly, the baffle ring supporting frame is connected to the outer side of the baffle ring, and radial and axial limiting of the baffle ring supporting frame is achieved through the elastic limiting assembly; the two sets of anti-off-line devices are symmetrically arranged, and the two ends of the pulley body are sleeved with the baffle rings of the anti-off-line devices correspondingly, so that the combination of the pulley body and the anti-off-line devices can be suitable for safe winding of lifting ropes at different lifting heights, and universality is achieved. The on-column mounting seat comprises an adjustable seat body and a clamping and limiting assembly fixed on the adjustable seat body; and the pulley body, the pulley body mounting seat and the assembly body of the anti-off-line device are fixed on the adjustable seat body of the on-column mounting seat through the pulley body mounting seat, and can be mounted on steel structure columns with different sizes.

    本发明公开了一种在钢结构柱上易装卸的通用型滑轮装置,包括滑轮体、滑轮体安装座、防脱线装置和柱上安装座;滑轮体为圆柱体,其两端通过轮轴安装于滑轮体安装座上;防脱线装置包括挡环、挡环支撑架和弹性限位组件,挡环支撑架连接于挡环的外侧,挡环支撑架通过弹性限位组件实现径向和轴向限位;防脱线装置有对称布置的两组,它们的挡环分别套于滑轮体两端,使滑轮体与防脱线装置的组合体可适用于不同提升高度安全缠绕提升绳,具有通用性;柱上安装座包括可调节的可调节座体和固定于其上的卡紧限位组件;滑轮体、滑轮体安装座及防脱线装置的装配体通过滑轮体安装座固定于柱上安装座的可调节座体上,可在不同尺寸的钢结构柱上安装。
