Vehicle-mounted multifunctional folding ladder
The invention discloses a vehicle-mounted multifunctional folding ladder, and relates to the technical field of construction folding apparatuses. The adopted technical scheme is as follows: the middle parts of two columns (A) are respectively sleeved by a slidable locking sleeve; two ends of a crossbeam (B) are welded to the locking sleeves on the columns (A); a nut shaft sleeve (A) is sleevedly connected to a screw rod (A); a recessed support is welded on two locking sleeves on the B shaft; two side of the other end of the recessed support are respectively welded to the locking sleeves which are sleeved on two columns (B); and a screw rod (B) is sleevedly connected to a nut shaft sleeve (B). The provided ladder is supported by a vehicle frame, columns, and a fixed support, thus an operator on the ladder will not lose the balance, and the accident is avoided. Moreover, the carriage bottom is provided with universal wheels and wheels, and thus the ladder can be transported easily. The motors arranged on the tops of the two sides of the folding ladder can drive the screw rods to rotate through a gear box, the nut shaft sleeves are sleeved on the screw rods and connected to a horizontal plate through the support so as to achieve the elevation of folding ladder, and the folding ladder can be used in different heights therefore.
