The slewing bearing fixing device for the crane comprises a slewing bottom plate, a slewing bearing assembly and a plurality of power wheel sets, the slewing bottom plate is fixed to a plane through bolts, an annular rail A is arranged on the top end face of the slewing bottom plate, an annular rail B is arranged on the outer side of the slewing bottom plate, and the slewing bearing assembly is arranged in the middle of the slewing bottom plate; the slewing bearing assembly is provided with an inner supporting piece and an outer supporting piece, the inner supporting piece is welded to a tower column at the bottom of the tower crane, a circle of reinforcing rib is arranged on the outer side of the inner supporting piece, and a plurality of supporting studs are integrally connected to the periphery of the reinforcing rib and distributed at intervals; the outer supporting piece is arranged outside the inner supporting piece, and the outer supporting piece is in the shape of a circular truncated cone with the narrow upper portion and the wide lower portion. According to the invention, not only can the rotation function be realized, but also the supporting function as a rotation platform is realized, the load generated by a tower column, a tower body and a lifted object at the bottom of the tower crane can be borne and transmitted, and a better supporting and fixing effect is achieved.

    本发明公开了一种起重机用回转支承固定装置,包括回转底板、回转支承组件与多套动力车轮组,其中回转底板通过螺栓固定于平面,回转底板顶端面设有一环形轨道A,回转底板外侧设有一环形轨道B,回转底板中间设有回转支承组件;所述回转支承组件具有内支承件、外支承件,其中内支承件焊接于塔式起重机底部的塔柱,内支承件外侧设有一圈加强筋,加强筋外周一体连接有多根支承螺柱,且多根支承螺柱间隔分布;所述外支承件设于内支承件外,外支承件为一上窄下宽的圆台形状。本发明既能实现回转功能,又实现了作为回转平台的支承功能,能承受及传递塔式起重机底部的塔柱、塔身和起吊物体产生的载荷,起到更好的支撑固定效果。
