The invention discloses an extensible gantry type port crane. The extensible gantry type port crane comprises a gantry frame, a hoisting mechanism and an extension mechanism; the hoisting mechanism ismounted in the portal frame; and the extension mechanism is mounted on the portal frame. In the using process, a threaded rod is driven to rotate through an internal motor of a fixed plate, a threaded sleeve moves downwards to push telescopic sleeves outwards, and a fixed base makes contact with the ground and is fixed; pulleys slide to designated positions along sliding rails, a hoisting rope islowered through a hoisting electric hoist so that a hook can be placed below to hook an object, when a box-shaped object needs to be hoisted, on the box is manually clamped by clamping plates, and two different object hooking modes can meet different hoisting requirements; and the extension mechanism moves outwards to hook up a heavy object, then an extension steel frame slides inwards to move the object from the position between two L-shaped rods to the position below a gantry transverse frame to be put down, long-distance object transportation is completed, equipment does not need to be integrally moved, transportation is more stable, manpower is saved, and transportation time is saved.
本发明公开一种可延伸龙门式港口起重机,包括:龙门架、起重机构、延伸机构;龙门架内安装有起重机构;龙门架上安装有延伸机构;使用时,通过固定板的内部电机带动螺纹杆转动从而使螺纹套向下移动将伸缩套筒向外推动,使固定底座接触地面并固定;滑轮沿着滑轨滑动到指定位置,通过起重电动葫芦下放起重绳从而将挂钩放到下方进行钩取物品,当需要吊取箱状物时,通过手动将夹板夹到箱子上,两种不同的钩取物品方式可以适应不同的起重要求;通过延伸机构向外移动将重物钩起,然后延伸钢架向内滑动将物品从两个L形杆中间移动到龙门横架下方放下,完成了较远距离的物品运输,无需整体挪动设备,运输更加的稳定,节省了人力,节约了运输时间。
