The invention relates to the field of engineering machinery, in particular to a supporting leg disc retracting and releasing mechanism and a crane. The supporting leg disc retracting and releasing mechanism comprises a supporting leg, a retracting and releasing support, a supporting leg disc and first fixing pins, wherein the retracting and releasing support is rotatably connected with the supporting leg, the supporting leg disc is slidably connected with the retracting and releasing support and the supporting leg, the first fixing pins are used for being connected with the supporting leg discand the supporting leg so as to limit sliding of the supporting leg disc relative to the supporting leg, and the first fixing pins can further used for being connected with the support leg disc and the retracting and releasing support so as to limit the sliding of the support leg disc relative to the retracting and releasing support. According to the supporting leg disc retracting and releasing mechanism, the operation efficiency of the crane adopting the supporting leg disc retracting and releasing mechanism can be improved.
本发明涉及工程机械领域,具体而言,涉及一种支脚盘收放机构和起重机。一种支脚盘收放机构,包括支腿、收放支架、支脚盘及第一固定销;收放支架与支腿可转动地连接,支脚盘与收放支架及支腿可滑动地连接;第一固定销用于与支脚盘和支腿连接,以限制支脚盘相对于支腿的滑动;还可以用于与支脚盘及收放支架连接,以限制支脚盘相对于收放支架的滑动。该支脚盘收放机构能够提高采用该支脚盘收放机构的起重机的作业效率。
