The invention discloses a frame lifting platform containing a power hydraulic driving mechanism, which comprises a lifting platform assembly and a stand column frame arranged around the lifting platform assembly, a platform lifting hook connected with a sliding piece on the stand column frame is arranged on the lifting platform assembly, and the sliding piece on the stand column frame is connected with a rope of a winch for driving the frame lifting platform. A driving mechanism for hydraulically driving the winch to start is arranged on the winch; the driving mechanism comprises an assembly assembled with the winch, and the side face, away from the movement direction of the winch, of the assembly is a continuous concave-convex tooth-shaped surface which is formed by smooth transition of a plurality of curved surfaces. And the driving mechanism further comprises a hydraulic assembly which is matched with the components and is used for sequentially or simultaneously extruding and pushing the convex curved surfaces. According to the invention, the heavy winch can be effectively driven through the improved hydraulic driving mechanism, and then the lifting of the frame lifting platform is realized through the winch; the winch can be driven to rotate more effectively by gradually applying force, and the total energy consumption required by driving equipment is reduced.

    本发明公开了一种含有动力液压驱动机构的框架升降台,包括升降台总成以及设置在升降台总成周围的立柱框架,升降台总成上设有与立柱框架上的滑动件相连的平台吊钩,立柱框架上的滑动件与驱动框架升降台的卷扬机的绳缆相连,卷扬机上设有液压驱动卷扬机启动的驱动机构;驱动机构包括与卷扬机组装的组件,组件其远离卷扬机运动方向的侧面为连续凹凸相间的齿形表面且此表面由若干个曲面平滑过渡而成;驱动机构还包括与前述组件配套设置的用于依次或同时挤推凸曲面的液压组件。本发明可通过其改进的液压驱动机构有效驱动大重量的卷扬机,再通过卷扬机实现框架升降台的升降;可以实现逐渐发力来更有效驱动卷扬机的转动,减少驱动设备所需的总的能耗。
