The invention relates to the technical field of tower crane bases, in particular to a movable tower crane base which comprises a base frame, an inner frame is arranged in the middle of the base frame, a sliding groove is formed in the inner frame, a sliding block is arranged in the sliding groove in a sliding mode, a protruding handle is arranged at the bottom of the sliding block, and a protruding shaft is arranged on a protruding seat on the side edge of the base frame. The convex shaft is rotationally sleeved with an L-shaped supporting piece, the middle of the L-shaped supporting piece is rotationally connected with the convex shaft, meanwhile, the convex handle is in sliding contact with the top side of the transverse section of the bottom of the L-shaped supporting piece, in the initial state, the top ends of the L-shaped supporting piece are away from each other, and meanwhile the bottom ends of the L-shaped supporting piece upwarp to be away from the ground. In the using process, the sliding blocks move in the sliding grooves to push the protruding handles to transversely move to push the L-shaped supporting pieces to swing, the lower hem of the bottom end makes contact with the ground, the inner hem of the top end abuts against the wall of the tower crane, the multiple sets of protruding bases are arranged on the peripheral side of the side edge of the base frame, and the multiple sets of L-shaped supporting pieces complete auxiliary supporting on the tower crane from the peripheral side.

    本发明涉及塔吊基座技术领域,具体是指一种移动式塔吊基座,包括基座框,所述基座框中部设置有内架,所述内架上开设有滑槽,所述滑槽中滑动设有滑块,所述滑块底部设置有凸柄,所述基座框侧边凸座上设置有凸轴,所述凸轴上转动套设有L型支撑件,所述L型支撑件中部与凸轴转动连接,同时所述凸柄与L型支撑件底部横向段顶侧滑动接触,初始状态下L型支撑件顶端相互远离,同时底端上翘远离地面,使用时通过滑块在滑槽中移动推动凸柄横移推挤L型支撑件摆动,底端下摆接触地面,顶端内摆紧抵在塔吊壁上,所述凸座在基座框侧边周侧设置有多组,多组L型支撑件从周侧完成对塔吊的辅助支撑。
