Single-longitudinal-beam vehicle-mounted folding working ladder
The single-longitudinal-beam vehicle-mounted folding working ladder comprises a longitudinal beam, a bottom supporting beam is arranged at the lower end of the longitudinal beam, the bottom supporting beam is perpendicular to the longitudinal beam, and a plurality of ladder sections are hinged to the left side and the right side of the longitudinal beam at equal intervals in the axis direction of the longitudinal beam; one end of each ladder section is a sliding hinged end, and the other end is a free end; the sliding hinge ends of the ladder sections are provided with long round sliding holes and are in sliding hinge joint with the longitudinal beams through pin shafts; when the pin shaft is located at the first end of the long round sliding hole and the included angle between the ladder section and the longitudinal beam is 0 degree, the ladder section is limited in a folded state; and when the pin shaft is positioned at the second end of the long round sliding hole and the included angle between the ladder section and the longitudinal beam is 90 degrees, the ladder section is limited in an unfolded state and is parallel to the bottom supporting beam. The single longitudinal beam structure is adopted, the ladder sections can be folded in the longitudinal beam direction, and the ladder has the advantages of being small in occupied space, light in weight and easy to operate and is suitable for being arranged on a vehicle with a long placing space and a narrow section.
本发明公开了一种单纵梁车载折叠工作梯，包括纵梁，纵梁的下端设有底支撑梁，底支撑梁与纵梁相互垂直，纵梁的左右两侧均沿自身轴线方向等间距铰接有多个梯节；梯节的一端为滑动铰接端，另一端为自由端；梯节的滑动铰接端设有长圆滑孔，梯节的滑动铰接端通过销轴与纵梁滑动铰接；当销轴位于长圆滑孔的第一端，且梯节与纵梁之间的夹角为0°时，使梯节限位于折叠状态；当销轴位于长圆滑孔的第二端，且梯节与纵梁之间的夹角为90°时，使梯节限位于展开状态，且梯节与底支撑梁相互平行。本发明采用单纵梁结构，梯节可实现沿纵梁方向折叠，具有占用空间小、重量轻、操作简单的优点，适用于布置于放置空间长、截面狭小的车辆上。
