The invention discloses a multi-stage displacement adjustable hydraulic lifting mechanism. The multi-stage displacement adjustable hydraulic lifting mechanism comprises a fixed base, a shear fork armframe, a hydraulic cylinder, a lifting platform, sliding platforms and a guardrail. The at least two sliding platforms are arranged and comprise the first sliding platform and the second sliding platform, and the bottom of the first sliding platform is arranged on the lifting platform through a first linear sliding rail. A first displacement air cylinder is transversely arranged on the side wall of the lifting platform, a first driving block is arranged at the driving end of the first displacement air cylinder and is correspondingly fixed to the side wall of the first sliding platform, and thebottom of the second sliding platform is arranged on the first sliding platform through a second linear sliding rail. A second displacement air cylinder is arranged on the side wall of the first sliding platform, and a second driving block is arranged at the driving end of the second displacement air cylinder and is correspondingly fixed to the side wall of the second sliding platform. Accordingto the mechanism, the standing area is adjusted through multi-stage displacement, multiple persons can work at the same time without crowding, the use stability is good, and safety is high.

    本发明揭示了一种多级位移可调液压升降机构,包括固定底座、剪叉臂架、液压缸、升降平台、滑动平台以及护栏,所述滑动平台设置有至少两个包括第一滑动平台和第二滑动平台,所述第一滑动平台底部通过第一直线滑轨设置于升降平台上,所述升降平台的侧壁横向设置有第一位移气缸,所述第一位移气缸的驱动端设置有第一驱动块与第一滑动平台的侧壁对应固定,所述第二滑动平台底部通过第二直线滑轨设置于第一滑动平台上,所述第一滑动平台的侧壁设置有第二位移气缸,所述第二位移气缸的驱动端设置有第二驱动块与第二滑动平台的侧壁对应固定。本发明采用多级位移调节站立面积,可实现多人同时作业且不拥挤,使用稳定性好,安全性高。
