The invention provides a crane frame, and belongs to the technical field of cranes. The car frame comprises a box-type structure car frame body formed by combining a bottom plate, a web plate and a cover plate, first arc-shaped protrusions extending in the horizontal direction of the two sides are symmetrically arranged on the upper surface of the cover plate located in the car frame body, and a seat ring is arranged between the first arc-shaped protrusions. A second arc-shaped protrusion extending in the same horizontal direction is arranged at the position, below the first arc-shaped protrusion, of the bottom plate of the cover plate, a supporting plate for supporting the seat ring is arranged between the first arc-shaped protrusion and the second arc-shaped protrusion, and an outer transition plate connected with the web plate is arranged on the supporting plate. The web plate, the outer transition plate and the supporting plate form a smooth curved surface structure, and the two ends, in the vertical direction, of the outer transition plate are connected with the edge of the cover plate and the edge of the bottom plate correspondingly. According to the invention, the abrupt change of the section of the frame can be reduced, the strength and local stability of the frame are improved, the production efficiency is also improved, and the cost is reduced.

    本发明提供了一种起重机车架,属于起重机技术领域。本发明包括由底板、腹板以及盖板组合而成的箱型结构车架本体,位于车架本体中的盖板上表面对称设有向两侧水平方向进行延伸的第一弧形凸起,位于该第一弧形凸起之间设置有座圈,位于所述盖板的第一弧形凸起下方的底板处设有向相同水平方向进行延伸的第二弧形凸起,所述第一弧形凸起与第二弧形凸起之间设有对座圈进行支撑的支撑板,所述支撑板上设置有与所述腹板进行连接的外过渡板,所述腹板、外过渡板以及支撑板形成平滑曲面结构,所述外过渡板在竖向上的两端分别与盖板以及底板的边缘连接。本发明可以减少车架的截面突变,提高了车架强度以及局部稳定性,同时也提高了生产效率,降低了成本。
