The invention provides a navigation tunnel traction portal crane, and relates to the technical field of ship tunnel traction passing, the height of a portal crane main beam is reduced by starting a hydraulic assembly, a mooring rope extending out of a cable winding mechanism is connected to a ship mooring column, and a cart running mechanism slides along a curved guide rail on a navigation tunnel bank. The traction portal crane is suitable for a curved navigation tunnel, after the traction portal crane travels to the terminal point of the tunnel, a hydraulic assembly is started, a portal crane main beam is lifted, the ship is started, penetrates through the lower portion of the portal crane main beam and leaves the navigation tunnel, and the ship can be dragged through a short traction rope. The technical problems that in the prior art, traction operation and cable hanging of the ship in the long-distance curve type navigable tunnel are difficult, and air in the tunnel is polluted under the condition of long-time operation in a self-propulsion mode are solved.
本发明提供了一种通航隧道牵引门机,涉及船舶隧道牵引通行技术领域,通过启动液压组件降低门机主梁的高度,卷缆机构伸出的系缆绳连接在船舶系缆柱,大车运行机构沿着通航隧道岸上的曲线导轨滑动移动,使通航隧道牵引门机整体曲线运动,卷缆机构的系缆绳带动船舶曲线移动,适用于曲线型通航隧道,行驶到隧道终点后,液压组件启动,升高门机主梁,船舶启动,从门机主梁下穿过,驶离通航隧道,实现使用较短的牵引绳即可对船舶进行牵引,且又不影响船舶的正常驶离,缓解了现有技术中存在的长距离曲线型通航隧道内船舶牵引运行、挂缆困难,采用自航形式在长时间运行情况下对隧道内空气产生污染的技术问题。
