The invention provides a crane and a crane rope deflecting angle adjusting method, and relates to the technical field of engineering machines. The crane further comprises a rotation mechanism and a drive mechanism. The rotation mechanism is rotationally connected to a bridge around the first axis. A sliding wheel is rotationally connected to the rotation mechanism around the second axis. The second axis is parallel to the axial direction of a winch. The included angle is formed between the first axis and the second axis. The drive mechanism is connected to the rotation mechanism so as to drivethe rotation mechanism to rotate around the first axis, accordingly, the position of the sliding wheel relative to the winch in the axial direction of the winch is adjusted, and the deflecting angleof a rope from the winch is reduced when the rope enters the sliding wheel. The crane rope deflecting angle adjusting method comprises the step that the drive mechanism is controlled to drive the rotation mechanism to rotate, and accordingly the position of the sliding wheel relative to the winch in the axial direction of the winch is adjusted. According to the crane and the crane rope deflectingangle adjusting method, the deflecting angle of the rope from the winch can be reduced when the rope enters the sliding wheel, and the rope is not prone to abrasion.

    本发明提供了一种起重机和起重机绳索偏角调整方法,涉及工程机械技术领域。起重机还包括转动机构和驱动机构,转动机构绕第一轴线转动连接于桥架,滑轮绕第二轴线转动连接于转动机构,第二轴线和卷扬的轴向平行,第一轴线和第二轴线之间具有夹角,驱动机构连接于转动机构以驱动转动机构绕第一轴线转动,进而调整滑轮在卷扬的轴向上相对卷扬的位置,以减小来自卷扬的绳索在进入滑轮时的偏折角度。起重机绳索偏角调整方法包括控制驱动机构驱动转动机构转动,以调整滑轮在卷扬的轴向上相对卷扬的位置。本起重机和起重机绳索偏角调整方法能够使来自卷扬的绳索在进入滑轮时的偏折角度减小,从而使得绳索不易磨损。
