The invention discloses an avoiding type bearing supporting leg mechanism which comprises a cylindrical supporting structure, a lead screw is rotationally installed in the supporting structure and driven by a power device, a push rod is arranged on the lead screw in a threaded and sleeved mode, the push rod is installed in the supporting structure, and a spiral guide groove is formed in the peripheral wall of the push rod. A guide block is fixedly arranged on the inner side wall of the supporting structure and located in the spiral guide groove, and a bearing supporting lug is fixedly arrangedon the push rod. The invention aims to provide the avoiding type bearing supporting leg mechanism, the supporting leg mechanism can be separated from a launching pad in the turning-out and retractingprocess of the launching pad, and the supporting leg mechanism can reliably and stably support the launching pad under the condition that a rocket is erected in place.
本发明公开了一种避让式承载支腿机构,其包括呈筒状的支撑结构,所述支撑结构内转动安装有丝杠,所述丝杠通过动力装置驱动,所述丝杠上螺纹套装有推杆,所述推杆内装于支撑结构内,所述推杆的外周壁上设有螺旋导向槽,所述支撑结构的内侧壁上固定设有导向块,所述导向块位于所述螺旋导向槽内,所述推杆上固定设有承载支耳。其目的是为了提供一种避让式承载支腿机构,在发射台翻出及收回过程中可实现支腿机构与发射台的分离,在火箭起竖到位条件下又可实现支腿机构对发射台的可靠、稳定支撑。
