The invention provides a portable offshore platform outboard metal ladder structure which comprises a ladder body, a fixing frame and a driving box, the ladder body comprises an inner ladder and an outer ladder, the inner ladder comprises a pair of inner longitudinal rods and inner foot bars, the side edges of the inner longitudinal rods are uniform in width, the inner foot bars are parallelly arranged between the inner longitudinal rods at intervals, and the outer ladder comprises a pair of outer longitudinal rods which are longitudinally arranged. The outer foot bars are arranged between the outer longitudinal rods in parallel at intervals, and the outer ladder and the inner ladder realize relative contraction and extension movement by arranging first sliding blocks; the inner ladder is fixed on a ship body through a fixing frame; and a driving mechanism is arranged in the driving box and used for driving the first sliding block to move in the length direction of the inner longitudinal rod. According to the structure, the inner ladder is fixed on the ship body, and when the outer ladder is not used, the outer ladder moves upwards along the inner ladder and is attached to the outer part of the outer ladder, so that the ladder body cannot sink into seawater during normal navigation, the ladder body is prevented from being corroded by the seawater, and the resistance of the seawater can also be reduced.

    本发明提供了一种便携式海上平台舷外金属梯结构,包括梯体、固定架以及驱动箱,其中,梯体包括内梯和外梯,内梯包括一对侧边宽度均匀的纵向设置的内纵杆,和间隔平行设置在该对内纵杆之间的内踏杆,外梯包括一对纵向设置的外纵杆,和间隔平行设置在该对外纵杆之间的外踏杆,外梯和内梯通过设置第一滑块实现相对收缩、延伸的移动;内梯通过固定架固定于船体;驱动箱,内设有驱动机构,用于驱动第一滑块沿内纵杆的长度方向移动。这种结构使得内梯固定在船体上,在不使用外梯时,将外梯沿内梯向上移动附于其外部,如此,在正常航行中梯体不会没入海水中,避免梯体被海水腐蚀,也能减小海水的阻力。
