The invention relates to the technical field of portal frames, in particular to a portal frame air dam-turning transportation device and a transportation method, and provides the portal frame air dam-turning transportation device aiming at the problem that goods hoisted in the air are prone to large-amplitude rotation, the portal frame air dam-turning transportation device comprises two supporting beams, and longitudinal beams are arranged at the upper ends of the supporting beams correspondingly; the clutch plate is provided with a locking device matched with the pull rope, the locking device comprises a movable connecting plate and two clamping seats, and the inner sides of the two clamping seats are respectively provided with two opened arc-shaped clamping plates; when the connecting plates move towards the inner side, a structure that the clamping seats and the arc-shaped clamping plates synchronously move towards the inner side and then the arc-shaped clamping plates are folded towards the inner side after the arc-shaped clamping plates move to designated positions can be formed; a large-span long-distance portal frame can be built over a hydropower station, automatic hoisting wharfs are built at the upstream end and the downstream end of the portal frame, the transportation efficiency is high, the ship type of a transportation ship is larger, the logistics cost is greatly reduced, the dam passing amount bottleneck problem is solved, and the rotation amplitude of goods hoisted in the air is reduced.

    本发明涉及龙门架技术领域,尤其是涉及一种龙门架空中翻坝运输装置及运输方法,针对吊装在空中的货物容易大幅度旋转,提供一种龙门架空中翻坝运输装置,包括两个支撑梁,所述支撑梁上端分别设有纵梁,离合板上设有与拉绳相配合的锁紧装置,锁紧装置包括可移动的连接板,锁紧装置还包括两个夹座,两个夹座内侧分别设有两个张开的弧形夹板,所述连接板向内侧移动时可构成夹座、弧形夹板同步向内侧移动在移动到指定位置后弧形夹板又会向内侧合拢的结构;能够在水电站上空建设大跨度长距离龙门架,龙门架上下游两端修建自动化吊装码头,运输效率高,运输船舶船型更大,大大降低物流成本,解决过坝量瓶颈难题,降低吊装在空中货物的旋转幅度。
