The invention discloses an unlimited slewing device of a marine crane, which is characterized in that the bottom of a crane slewing body is rotatably arranged on a barrel base, the unlimited slewing device is arranged at the axis of the crane slewing body rotating relative to the barrel base, a fixed part is arranged in the barrel base, and a rotating part is arranged in the crane slewing body; the rotating part is provided with a rotating end inserted into the fixed part, the rotating end is provided with a sliding ring part and a hydraulic oil core column, a brush carrier assembly and a hydraulic oil shell are sequentially and correspondingly arranged in the fixed part, the brush carrier assembly is arranged on the side face of the sliding ring part, and the hydraulic oil core column is inserted into the hydraulic oil shell; the hydraulic oil shell and the hydraulic oil core column are rotationally matched, and a positive-pressure purging cavity is formed in the end close to the sliding ring part. The infinite slewing device is a key component for transmitting current and signals, and is suitable for equipment which needs to continuously rotate and cannot be connected by a fixed electric wire. And the positive pressure purging cavity capable of continuously discharging oil is arranged between the hydraulic oil and the conductive slip ring, so that abnormal conditions such as pollution caused by oil escaping can be avoided.

    本发明公开了一种船用起重机无限回转装置,起重机回转体底部转动设置在筒体底座上,起重机回转体相对于筒体底座转动的轴心处设有无线回转装置,固定部设置于筒体底座内,旋转部设置于起重机回转体内,旋转部设有插入固定部内的转动端,转动端上设有滑环部、液压油芯柱,固定部内依次对应设有刷架组件、液压油壳体,刷架组件设置于滑环部侧面,液压油芯柱插入液压油壳体内;液压油壳体和液压油芯柱转动配合且靠近滑环部一端设有正压吹扫腔。无限回转装置是传输电流及信号的关键部件,适用于需要连续旋转运动而不能使用固定电线连接的设备。并且在液压油和导电滑环之间设置可以持续排油的正压吹扫腔,可以避免油液逸出造成污染等异常情况。
