The invention discloses an optical cable winch drum with a built-in optical fiber slip ring. The optical cable winch drum comprises a drum body, the optical fiber slip ring, a hollow rotating shaft and a hollow fixed shaft, the barrel body is connected with the winch frame through the hollow rotating shaft; the barrel body and the hollow rotating shaft can synchronously rotate relative to the winch frame; the hollow fixed shaft is arranged in the hollow rotating shaft, is connected with the winch frame and is relatively fixed with the winch frame; the optical fiber slip ring is arranged in the hollow fixed shaft and is coaxial with the hollow rotating shaft, the optical fiber slip ring comprises an optical fiber slip ring rotor and an optical fiber slip ring stator which are coaxially arranged, and the optical fiber slip ring rotor and the optical fiber slip ring stator can rotate relatively; the optical slip ring rotor is fixedly connected with the hollow rotating shaft; the optical slip ring stator is fixedly connected with the hollow fixed shaft; one end of the optical cable extends into the cylinder body and then is connected with the smooth ring rotor; the waste inner space of the winding drum in the traditional structure of the optical cable winch is fully utilized, the structure is compact, the weight is light, and the size is small.
本发明公开了一种内置光纤滑环的光缆绞车卷筒,包括:筒身、光纤滑环、空心转轴和空心定轴;筒身通过空心转轴与绞车框架连接,筒身和空心转轴可同步相对于绞车框架旋转;空心定轴设置在空心转轴内,空心定轴与绞车框架连接,且与绞车框架相对固定;光纤滑环设置在空心定轴内,且与空心转轴同轴,光纤滑环包括同轴设置的光纤滑环转子和光纤滑环定子,光纤滑环转子和光纤滑环定子可进行相对旋转运动;光滑环转子与空心转轴固定连接,光纤滑环定子与空心定轴固定连接;光缆的一端伸入到筒身内部后,与光滑环转子连接;本发明充分利用光缆绞车传统结构中被浪费的卷筒内部空间,结构紧凑、质量轻、体积小。
