The invention belongs to the technical field of cranes, and discloses a cargo boom slewing device of a port crane, which comprises a supporting seat and a shell base, the shell base is positioned outside the supporting seat and is used for protecting and supporting the supporting seat, and the cargo boom slewing device further comprises a protection mechanism. Through cooperation of the power module, the supporting frame, the transmission assembly, the second balancing weight and other structures, the device has a good protection effect on the crane, the supporting main shaft rotates to drive the crane body to rotate in the operation process of the power module, meanwhile, the supporting frame also rotates, and the crane body is protected; the second transmission wheel drives the connecting shaft and the second balancing weight to rotate in the direction opposite to the revolution direction of the second transmission wheel, and the rotation of the second balancing weight can generate angular power in the direction opposite to the revolution direction of the second balancing weight, so that the inertia of the crane body suspension arm in the rotation process is reduced, and the abrasion of the device is reduced.

    本发明属于起重机技术领域,且公开了一种港口起重机的起重臂回转装置,包括支撑座和外壳底座,所述外壳底座位于支撑座外部用于对支撑座进行防护和支撑,还包括,防护机构。本发明通过动力模组、支撑架、传动组件和第二配重块等结构之间的配合,使得装置具有对起重机具有良好的防护作用,通过动力模组在运行过程中使得支撑主轴旋转带动起重机本体旋转,同时支撑架也会发生旋转,使得第二传动轮带动连接轴和第二配重块发生与第二传动轮公转相反方向的旋转,由于第二配重块的自转会产生与其公转方向相反的角动力,进而降低起重机本体吊臂在发生旋转过程中的惯性,进而降低装置的磨损。
