Ladder hanging rack structure

The invention discloses a ladder hanging rack structure, relating to the field of airplane structure design. A hanging rack support is fixedly arranged on a fixed beam; the fixed beam is provided with two hanging points; the hanging rack support is arranged at the places where the hanging points are; the hanging rack support is a single-ear hollow support; a pin shaft a and a pin shaft b are arranged to be in interference fit with the ear hole of the hanging rack support; a quick release pin mounting hole is formed in one end, different from a limiting platform, of the pin shaft b; a quick release pin and the quick release pin mounting hole are connected in a matching manner to limit a ladder hanger on a pin shaft be which is located between the hanging rack support and the quick release pin. The ladder hanging rack structure provided by the invention is simple in structure and convenient to operate; as the pin shafts are arranged on the hanging rack support, and the quick release pin is arranged on one pin shaft to limit relative movement of the ladder hanger and the hanging rack support, a ladder can be separated from the hanging rack support only by driving the whole ladder along the same direction of the pin shafts during the disassembling of the ladder, labor intensity of workers is reduced, and the ladder hanging rack structure is high in stability, safe and reliable.
