Air sac device for rescuing

Abstract

The invention relates to an air sac device for rescuing. When emergencies such as earthquakes, fire hazards and the like occur and people are trapped under heavy objects, the key point for rescuing trapped people is to jack up the heavy objects in the first time. In general, the occurrence places of emergencies are buildings, and available gas sources in the buildings are used for aerating an airsac for jacking up the heavy objects pressing on the trapped people to realize self-rescuing, so that the trapped people can get out of hazard areas rapidly. When a fire extinguisher or a gas generator is taken as a gas source for aerating the air sac, the aerating duration is shorter under a certain pressure, so that piston rods of a plurality of hydraulic cylinders in the air sac stretch out tosupport against the top of the air sac while the air sac expands upwards and ejects during aeration. Under the support of the hydraulic cylinders, the air sac can be used for jacking the heavy objects stably and effectively. The air sac device and the fire extinguisher are arranged together in places such as buildings and the likes, so that the self-rescuing capability can be effectively improved.

Description

technical field [0001] The invention relates to the field of rescue and lifesaving, in particular to an air bag device for rescue. Background technique [0002] When emergencies such as earthquakes and fires occur, if someone is pressed by heavy objects, being able to save themselves in the first time is an important way to get out of the dangerous area, and obtaining tools for rescue is the decision to solve whether they can escape factor. Place the rescue airbag or air cushion under the heavy object, and then inflate the airbag or air cushion through the air source, so as to lift the heavy object and escape the trapped person. However, the existing rescue airbag or air cushion structure is mainly a hollow device without supports, which fully utilizes gas pressure to support heavy objects, and there are certain safety hazards, mainly because the airbag or air cushion is generally poor in sealing performance, and the airbag is likely to be damaged during rescue work. Or th...

Problems solved by technology

However, the existing rescue airbag or air cushion structure is mainly a hollow device without supports, which fully utilizes gas pressure to support heavy objects, and there are certain safety hazards, mainly because the airbag or air cushion is generally poor in sealing performance, and the airbag is likely to be damaged during rescue work. Or the leakage of the air cushion under high pressure; or the leakage of the air bag or air cushion due to external reasons. At this time, the air bag or air cushion is unable to support heavy objects, which will cause secondary injury to the rescued

In addition, this type of rescue airbag or air cushion needs special high-pressure air supply equipment, and the manufacturing cost is relatively high. Therefore, the structure of the existing rescue airbag or air cushion is unreasonable, and the timeliness is poor, and rescue cannot be realized at the first time.
