The invention discloses a high-altitude working platform swing mechanism which comprises a rack, a working platform and an electric push rod. The working platform is mounted on the upper portion of the rack, a rotating arm is arranged in the center of the working platform, one end of the rotating arm is rotationally connected with the rack, and a movable connecting rod is hinged to the other end of the rotating arm; a driving connecting rod is hinged to the other end of the movable connecting rod; of the end, away from the movable connecting rod, of the driving connecting rod is hinged with the rack; and the electric push rod is installed on the rack, hinged to the middle of the driving connecting rod and used for driving the driving connecting rod to move and finally driving the working platform to rotate relative to the rack. According to the high-altitude working platform swing mechanism, the structure is simple, the overall mass is low, the stability of a whole vehicle can be improved, and meanwhile the load capacity of the working platform cannot be affected; and the high-altitude working platform swing mechanism is pushed by the electric push rod and does not belong to precision elements, and thus cost can be reduced.

    本发明公开了一种高空工作平台摆动机构,包括:机架,上部安装有工作平台;工作平台,中心处设有旋转臂,旋转臂一端与机架转动连接,另一端铰接有活动连杆,活动连杆另一端铰接有驱动连杆;驱动连杆远离活动连杆的一端与机架铰接;电动推杆,安装于机架,并与驱动连杆中部铰接,用于驱动驱动连杆运动,并最终带动工作平台相对机架旋转。根据本发明实施例的高空工作平台摆动机构,结构简单,整体质量较轻,可提高整车的稳定性,同时不会对工作平台的负载能力产生影响;通过电动推杆推动,且不属于精密元件,可降低成本。
