The invention relates to the technical field of engineering machinery, in particular to a boarding ladder and an engineering vehicle. The boarding ladder comprises a first ladder assembly of which the first end is suitable for hinging with the body; a second ladder assembly which is hinged to the second end of the first ladder assembly; a driving assembly which is used for driving the first ladder assembly to rotate relative to the vehicle body, so that the first ladder assembly has a folding position and an unfolding position forming a first preset angle with the horizontal plane; a transmission structure which is connected between the first ladder assembly and the second ladder assembly, and when the driving assembly drives the first ladder assembly to rotate, the transmission structure drives the second ladder assembly to move, so that when the first ladder assembly is located at the folding position, the second ladder assembly and the first ladder assembly are arranged in a folded mode; when the first ladder assembly is located at the unfolding position, the second ladder assembly is located at the unfolding position, and the included angle between the second ladder assembly and the horizontal plane is a second preset angle. The first ladder assembly and the second ladder assembly can be driven to fold and rotate only by arranging one driving assembly, and the structure is simple and compact.
本发明涉及工程机械技术领域,具体涉及一种登车梯、工程车辆,登车梯包括:第一梯组件,其第一端适于与车体铰接;第二梯组件,与第一梯组件的第二端铰接;驱动组件,用于驱动第一梯组件相对车体转动,使第一梯组件具有收拢位置、与水平面之间具有第一预设角度的展开位置;传动结构,连接在第一梯组件与第二梯组件之间,驱动组件驱动第一梯组件转动时,传动结构带动第二梯组件运动,以使第一梯组件位于收拢位置时,第二梯组件与第一梯组件折叠设置;第一梯组件位于展开位置时,第二梯组件位于与水平面之间的夹角为第二预设角度的打开位置。仅通过设置一个驱动组件可带动第一梯组件、第二梯组件折叠转动,结构简单紧凑。
