The invention discloses a hanging shear fork type lifting platform. The hanging shear fork type lifting platform comprises a mounting seat, two sliding grooves are formed in the bottom wall of the mounting seat, a mounting cavity is formed in the mounting seat, the mounting seat is rotationally connected with two threaded rods in a penetrating mode through bearings, one end of each threaded rod penetrates and extends into the corresponding sliding groove and is provided with threads with opposite rotating directions, the other end of each threaded rod penetrates and extends into the mounting cavity and is in interference fit with a worm gear, the section, located in the corresponding sliding groove, of each threaded rod is connected with two sliding blocks, the sliding blocks located on the same side are rotationally connected with a shear fork assemblies through pin shafts, the shear fork assemblies are jointly and rotationally connected with a lifting platform through pin shafts, and a driving device is arranged in the mounting cavity. Compared with a lifting platform directly driven by a hydraulic cylinder in the prior art, the lifting platform is simpler in structure, smaller in occupied area and more convenient to repair and maintain, and the lifting speed can be conveniently adjusted and controlled.

    本发明公开了一种悬挂剪叉式升降平台,包括安装座,所述安装座底壁开设有两个滑动槽,所述安装座内开设有安装腔,所述安装座通过轴承贯穿转动连接有两个螺纹杆,所述螺纹杆一端贯穿延伸至对应的滑动槽内并设置有旋向相反的螺纹,另一端贯穿延伸至所述安装腔内并过盈配合有蜗轮,所述螺纹杆位于滑动槽内的一段螺纹连接有两个滑块,位于同侧的所述滑块通过销轴转动连接有剪叉组件,所述剪叉组件共同通过销轴转动连接有升降台,所述安装腔内设置有驱动装置。本发明相较于现有技术直接通过液压缸驱动的升降平台,其结构更加简单、占地面积更小,维修与保养更加方便,且可以方便的调控升降速度。
