Abstract

The invention relates to the field of helicopter rescue and provides a helicopter hanging ladder for rescue. The hanging ladder comprises a power mechanism, a closed-loop-shaped hanging ladder body, and a second hanging wheel set, a first hanging wheel set and a plurality of supporting wheel sets which are in the same longitudinal plane, wherein the second hanging wheel set is arranged at a helicopter hatch in a stretching-out manner through a second arm frame, the first suspension wheel set extends out of the helicopter hatch through a first arm frame, the multiple supporting wheel sets are arranged on an inner wall of the helicopter cabin, the hanging ladder body is sequentially connected with the first hanging wheel set, a plurality of supporting wheel sets and the second hanging wheelset in a rolling fit mode, a part, located between the first hanging wheel set and the second hanging wheel set, of the hanging ladder body is in a suspended state, and the power mechanism is used fordriving the hanging ladder body to rotate in a circulating mode. The hanging ladder is advantaged in that circulating operation of the helicopter hanging ladder for rescue is guaranteed through the closed hanging ladder body and the power device, and thereby rescue efficiency is improved.

Description

technical field [0001] The invention relates to the field of emergency rescue, in particular to a helicopter hanging ladder for rescue. Background technique [0002] Helicopter rescue is widely used in various emergency rescue scenarios. For emergency rescue, the efficiency of rescue is particularly important. When the rescue environment is water, mountains, jungles and other areas that are not suitable for helicopter landing, the rescue hanging ladder plays a vital role. The rescue hanging ladder is an important hardware facility for emergency rescue, especially suitable for situations where there are many people waiting to be rescued and the time is tight. Helicopter rescue, and rapid deployment and rapid evacuation of field troops. [0003] In situations where the helicopter is not suitable for take-off and landing on water, jungles and mountains, the helicopter hovers in the air, and it is usually necessary to drop a hanging ladder or a rescue rope for rescue. Existing...
