Integrated hydraulically-driven two-stage telescopic lifting column
The invention relates to the technical field of hydraulic lifting roadblocks, and discloses an integrated hydraulically-driven two-stage telescopic lifting column which comprises an outer barrel, a lower-stage column body is slidably connected to the upper end of the inner side wall of the outer barrel, an upper-stage column body is slidably connected to the upper end of the inner side wall of the lower-stage column body, and a column body upper cover is fixedly connected to the top end of the upper-stage column body. And a two-stage synchronous hydraulic cylinder assembly is arranged at the central positions of the interiors of the outer barrel, the lower-stage column body and the upper-stage column body. The upper-stage cylinder body and the lower-stage cylinder body of the two-stage synchronous hydraulic cylinder assembly ascend and descend at the same speed at the same time, the upper-stage cylinder body and the lower-stage cylinder body are driven to ascend and descend at the same speed at the same time, common cognition of people on lifted objects is met, and the risk of collision accidents caused by misjudgment can be effectively avoided; the ascending and descending of the two-stage synchronous hydraulic cylinder assembly are driven by the pressure of hydraulic oil, so that the ascending and descending speeds are adjustable and controllable.
本发明涉及液压升降路障技术领域，公开了一种集成液压驱动的两级伸缩升降柱，包括外筒，所述外筒的内侧壁的上端滑动连接有下级柱体，所述下级柱体的内侧壁的上端滑动连接有上级柱体，所述上级柱体的顶端固定连接有柱体上盖，所述外筒、下级柱体和上级柱体的内部的中心位置共同设置有两级同步液压缸组件。本发明通过两级同步液压缸组件的上级缸体和下级缸体同时以相同的速度升降，带动上级柱体和下级柱体同时以相同的速度升降，符合人们对升降物体一般常识性认知，可以有效地避免误判而产生碰撞事故的危险，两级同步液压缸组件的上升和下降均通过液压油的压力驱动，从而上升和下降速度均可调可控。
