Helicopter rescue ladder device

Abstract

The invention discloses a helicopter rescue ladder device. The helicopter rescue ladder device comprises a fixing plate, a transition plate and a pedal, link plates are arranged among the fixing plate, the transition plate and the pedal, shaft rods are connected between the two ends of the link plates and the fixing plate, between the transition plate and the pedal, and mounting grooves are formed in the inner sides of the two ends of each link plate; fixing blocks are arranged in the mounting grooves; According to the invention, the fixing plate, the transition plate and the pedal are rotationally connected through the link plates, so that when rescue is needed, the bottom plate of the helicopter is directly converted into a ladder, and rescue workers can step on the ladder to climb into the helicopter body, so that the rescue workers can enter the helicopter more quickly and safely; personnel assistance is not needed, so that the consumption of human resources is reduced; through the design of the fixing grooves and the fixing blocks, the fixing blocks are inserted into the corresponding fixing grooves, and the angle of the device is fixed.

Description

technical field [0001] The invention belongs to the technical field of helicopter rescue components, and in particular relates to a helicopter rescue ladder device. Background technique [0002] Helicopter rescue is the application of helicopters to emergency rescue. It can reach the work site inaccessible by water and land more quickly, and carry out search and rescue, material delivery, air command and other tasks. It is the most effective emergency rescue commonly used by many countries in the world. [0003] Existing helicopter rescue usually has a winch equipment on the side of the rescue helicopter, and puts the lifeguard down to save people. Every time the lifeguard returns to the helicopter, because the bottom plate of the helicopter cannot be folded, the lifeguard can only go to the side of the helicopter , the person who manipulates the winch in the cabin pulls the lifeguard into the cabin, and for making the lifeguard enter the cabin more quickly and easily, we pr...

[0003] Existing helicopter rescue usually has a winch equipment on the side of the rescue helicopter, and puts the lifeguard down to save people. Every time the lifeguard returns to the helicopter, because the bottom plate of the helicopter cannot be folded, the lifeguard can only go to the side of the helicopter , the person operating the winch in the cabin pulls the lifeguard into the cabin. In order to make the lifeguard enter the cabin faster and easier, we propose a helicopter rescue ladder device
