Working method of rigid-flexible coupling airborne loading combined buffer device

Abstract

The invention discloses a working method of a rigid-flexible coupling airborne loading combined buffer device. The device comprises an airborne material storage box, a buffer spring, an inner buffer air bag, an inner spherical shell, an outer buffer air bag and an outer spherical shell. In the loading airborne landing process, the outer spherical shell deforms firstly, and first-stage buffering isachieved; then a folding buffer connecting piece deforms, and second-stage buffering is achieved; the outer buffering air bag is compressed, and the outer buffering air bag exhausts air and relievespressure outwards through an outer buffering air bag exhaust valve so that three-stage buffering is realized; the inner spherical shell is deformed after being subjected to a load so that four-stage buffering is realized; the buffer spring contracts subsequently to realize five-stage buffering; the inner buffer air bag is finally compressed and the inner buffer air bag exhausts air and relieves pressure outwards through the inner buffering exhaust valve, and six-stage buffering is achieved; by means of the multi-stage buffering method of the airborne landing device, impact energy can be absorbed stage by stage, the internal pressure of the buffering air bag can be prevented from being sharply increased, the buffering air bag is prevented from blasting, and therefore, the integrity of materials in the airborne landing device is effectively guaranteed.

Description

technical field [0001] The invention relates to the field of airborne safety protection for loaded objects, in particular to a working method of a rigid-flexible coupled airborne loaded combined buffer device. Background technique [0002] Loading airborne is to airdrop the required materials to the destination, which has great practical significance in aspects such as military affairs and earthquake relief. Since the airborne materials will bear a huge impact load on the ground at the moment of landing, in order to ensure the safe landing of the airborne materials for the subsequent use of the airborne materials by the ground receiving personnel, protective buffer devices must be used to reduce the damage to the materials caused by the impact load. [0003] In the actual loading airborne landing process, the following problems exist in the existing loading airborne device: [0004] 1. Most of the existing load-carrying airborne devices use large-area parachutes to decelera...

Problems solved by technology

However, this type of airborne device always has the problem of directly touching the ground or rebounding or even overturning, which will cause great damage to the equipment, and the accuracy of the landing site cannot be guaranteed, especially when it cannot adapt to bad weather and complex landing terrain. airborne

[0005] 2. In order to overcome the problem that the airdrop device directly touches the ground, a small part of the prior art designs an anti-turnover device on the airborne device and arranges a buffer protective airbag at the bottom of the device, but the buffer protective airbag arranged at the bottom of the device is easily caught by the ground when it touches the ground. Piercing by sharp objects causes the airbag to deflate or the internal pressure of the airbag is too high to cause the airbag to burst, which will cause fatal damage to the airdropped materials

[0006] 3. Most of the existing load airborne buffer devices use airbag buffer devices, and most of them are single-chamber airbag buffer devices with a single structure. There are no other forms of buffer devices, resulting in limited effective buffer strokes and buffer forms. Therefore, Can't play a good buffer effect on airborne materials
