The invention provides a portable hydraulic foldable crawling ladder, and belongs to the technical field of semi-trailer crawling ladders. The folding ladder comprises an upper folding ladder body and a lower folding ladder body which are connected in a hinged mode, the upper folding ladder body is hinged to a frame through a hinged connecting piece, a first driving structure capable of enabling the upper folding ladder body to rotate with the hinged connecting piece as the axis is arranged between the bottom of the upper folding ladder body and the frame, and a second driving structure capable of enabling the lower folding ladder body to rotate with the hinged position as the axis is arranged between the upper folding ladder body and the lower folding ladder body. The first driving structure and the second driving structure are connected with a control assembly. The unfolding and folding actions of the integral folding ladder are controlled by the electric switch, so that the folding state of the integral folding ladder can be quickly and flexibly controlled; the whole folding ladder is simple in structure, small in size after being folded and light in weight; after the whole folding ladder is unfolded and falls to the ground, the walking pedals are flat, walking is convenient, the hydraulic self-locking function is achieved, and the bearing capacity is large.

    本发明提供了一种便携式液压可折叠爬梯,属于半挂车爬梯技术领域。它包括铰接相连的上折梯和下折梯,上折梯通过铰接连接件与车架铰接,上折梯底部与车架之间设有能够使上折梯以铰接连接件为轴心转动的一号驱动结构,上折梯与下折梯之间设有能够使下折梯以铰接处为轴心转动的二号驱动结构,一号驱动结构和二号驱动结构连接有控制组件。整体折叠梯的展开跟折叠动作由电动开关控制,可快速且灵活地控制整体折叠梯的折叠状态;整体折叠梯结构简单,折叠后体积小,重量轻;整体折叠梯展开落地后行走踏板平展,便于行走且具有液压自锁功能,承载能力大。
