The invention discloses a dragging device which is used for releasing or limiting a drag chain. The dragging device comprises a base which is provided with a containing cavity used for containing thedrag chain and a first channel communicated with the containing cavity, a driving rod group which is movably assembled on the base and can move in the vertical direction, a lever component of which the middle part is pivoted on the base and one end is hinged to the driving rod group so as to rotate around a pivoting point, and a driven rod group which comprises a driven rod arranged in the first channel, wherein the end, away from the containing cavity, of the driven rod is hinged to the other end of the lever component, and the driving rod group drives the driven rod to move in the directionclose to or away from the containing cavity through the lever component. The invention further provides a ship provided with the dragging device. Opening or closing of the containing cavity in the dragging device can be achieved through the driving rod group, and the dragging device is simple in structure, small in number of component parts, light in weight, small in overall boundary dimension andsmall in occupied space.

    本发明公开了一种拖曳装置,其用于释放或限制拖链;包括:基座,其上设有用于容纳所述拖链的容纳腔和与该容纳腔连通的第一通道;主动杆组,其移动组设于所述基座上,并可沿竖直方向移动;杠杆构件,其中部枢接于所述基座上,其一端与所述主动杆组铰接,以绕枢接点转动;从动杆组,其包括一设于所述第一通道内的从动杆,所述从动杆远离所述容纳腔的一端与所述杠杆构件的另一端铰接,所述主动杆组通过所述杠杆构件驱动所述从动杆沿靠近和远离所述容纳腔的方向上运动。本发明还提供一种安装有上述拖曳装置的船舶。本发明拖曳装置中容纳腔张开或闭合能够通过主动杆组实现,且结构简单,且组成零部件少,质量轻,整体外形尺寸小,占用空间小。
