Problems solved by technology

[0004] The traditional helicopter rescue process is relatively inefficient because the rescuer needs to slide down to the trapped person with the rescue rope device to help him put the rope on the trapped person, and it is difficult to rescue in some small spaces due to the limited space. It can accommodate two people standing, not to mention the rescue personnel help the trapped people to tie the rescue rope, so it is difficult to complete the rescue work
Especially when the injured person is a body (such as abdomen) injured or a pregnant woman, etc.; when the body cannot bear force, it is more difficult to achieve with traditional rescue methods

Abstract

The invention discloses a self-adaptive crane auto-locked by gravity, which comprises a front support frame for a machine body and a rear support frame for the machine body, the front support frame for the machine body and the rear support frame for the machine body are connected to form a support box through a support rod, sliders are arranged in the front support frame for the machine body and the rear support frame for the machine body, the sliders are connected through a regulating spring, the regulating spring can drive the sliders to slide on the front support frame for the machine body or the rear support frame for the machine body, a cam is arranged between the sliders, a gear of the cam is connected with a gear rack for transmission, and a handle mechanism is arranged on a front end of the gear rack. By the adoption of the cam in the self-adaptive crane, trapped personnel (particularly suitable for a pregnant woman and a person injured on a body) can be automatically locked in rescue equipment during the rescue, help from extra rescuers is not needed, the efficiency on rescuing is increased, and the rescue task can be completed safely. The adaption on thickness of the arm, thickness of the body, and width of the body is strong, so that the self-adaptive crane can be applied in rescues in multiple narrow spaces, and escapes from a canyon, a mine, a high building in fire and the like.

Description

technical field [0001] The invention belongs to the field of rescue machinery and equipment, and in particular relates to a gravity self-locking self-adaptive hoist used in rescue. Background technique [0002] The timeliness of rescue in disasters and accidents is an important factor for the survival of those in distress. After the Second World War, with the development of rescue organizations and the improvement of rescue equipment, the speed of rescue has been greatly accelerated. The fire in the new building of the TV station, the heavy snowfall and avalanches in the northern Xinjiang region all highlighted the huge advantages of aviation rescue in emergency rescue. Aviation emergency rescue has become an indispensable and important part of the entire emergency rescue system, especially the aviation rescue emergency system with helicopters as the main body and other transport models as the supplement plays a huge role in disaster rescue [0003] The helicopter used for...
