The embodiment of the invention discloses an expansion joint steel wire rope hoisting structure, and belongs to the technical field of fire-fighting and rescue equipment. The expansion joint steel wire rope hoisting structure comprises a steel wire rope arranged between two adjacent expansion joints, a top steering wheel arranged at the top of the expansion joint located on the outer layer, and a wall penetrating wheel arranged at the bottom of the expansion joint located on the inner layer, the wall penetrating wheel penetrates through the expansion joint located on the inner layer, one end of the wall penetrating wheel is located on the outer side of the expansion joint located on the inner layer, the other end of the wall penetrating wheel is located on the inner side of the expansion joint located on the inner layer, and the steel wire rope winds around the top steering wheel, then winds around the wall penetrating wheel and reaches the inner side of the expansion joint located on the inner layer. The technical problem that the expansion length is small due to the fact that a hydraulic cylinder occupies the effective space of the expansion joint in an existing expansion cylinder structure is solved, and the expansion joint steel wire rope hoisting structure is widely applied to high-altitude fire fighting or rescue.
本发明实施例公开了一种伸缩节钢丝绳吊装结构,属于消防和救援装备技术领域,包括设置于相邻两节伸缩节之间的钢丝绳,位于外层伸缩节的顶部设有顶部转向轮,位于内层伸缩节的底部设有穿墙轮,所述穿墙轮贯穿所述内层伸缩节,一端位于所述内层伸缩节的外侧,另一端位于所述内层伸缩节的内侧,所述钢丝绳绕经所述顶部转向轮后缠绕所述穿墙轮后至所述内层伸缩节内侧。本发明解决了现有伸缩筒结构中液压缸占用伸缩节有效空间导致伸缩长度小的技术问题,广泛应用于高空消防或救援中。
