The invention relates to a revolving platform with retractable supporting legs. The platform comprises a rotating device and a retractable supporting leg device. The rotating device drives a bearing platform to rotate by driving a pinion to be engaged with the inner ring of a slewing bearing through a swing hydraulic cylinder. According to the retractable supporting leg device, the motion characteristics of a four-rod mechanism are utilized to achieve retracting and releasing of the supporting legs. The platform disclosed by the invention not only can load a large-load bearing platform, but also can satisfy the space utilization of the bearing platform to the greatest extent.
本发明涉及一种带有收放型支腿的回转平台。所述平台包括旋转装置和收放型支腿装置。所述旋转装置通过摆动液压缸驱动小齿轮与回转支承内圈的啮合来带动承载平台旋转;所述收放型支腿装置利用四杆机构的运动特性来实现支腿的收放动作。本发明所述平台不仅能负载大载荷承载平台,还能够最大程度的满足承载平台的空间利用。
