Expanding rescue device for ruin channel

Abstract

The invention discloses an expanding rescue device for a ruin channel. The expanding rescue device comprises three face expanding units, wherein the face expanding units are mutually hinged into a triangular mechanism through a supporting shaft and a supporting block; an expanding mechanism is connected in series to a lead screw; the lead screw is fixedly connected with a motor; a forward slide block and a backward slide block are arranged in a guide groove; and one end of a connecting rod is hinged with a slide block hinging hole, and the other end of the connecting rod is hinged with a connecting rod which is hinged with the forward slide block and a connecting rod which is hinged with the backward slide block. When the expanding rescue device is used, the motor is used for driving the lead screw to rotate, the forward slide block and the backward slide block are driven to move away from each other firstly, and the slide blocks are used for driving the supporting block to be folded; and after the three face expanding units are folded, the motor stops running, is put into a ruin gap and is restarted to run in a direction opposite to the folding direction, the forward slide block and the backward slide block move towards each other, and the ruin gap is expanded into a channel with a large section, so that the functions of transporting rescue materials and rescuing wounded persons are realized. The expanding rescue device has the advantages of high rescue work efficiency, low risk and high reliability.

Description

technical field [0001] The invention belongs to the technical field of disaster rescue engineering, and in particular relates to a ruin channel expansion rescue device. Background technique [0002] Natural disasters have threatened human security since ancient times. In recent years, landslide accidents caused by external factors such as mine accidents and earthquakes have occurred frequently, threatening people's property and personal safety. Earthquake rescue is divided into evacuation, transfer and simple, surface, shallow trapped and deep trapped rescue according to the degree. Trapped people can move freely during evacuation and transfer, and only need to be guided out of the dangerous area; simple trapping can usually be accomplished with bare hands through self-rescue and mutual rescue; shallow trapping on the surface requires certain rescue tools; and deep trapping It is the most difficult and the longest rescue time. According to statistics, in the 5.12 earthquak...

Problems solved by technology

[0003] At present, for the collapse caused by disasters such as mine accidents, landslides, and earthquakes, the rescue work mainly relies on top-down, surface-to-inside excavation and transportation. The shortcomings of this rescue method include: 1. Rescue The efficiency is very low; 2. With the increase of the buried depth of the injured, the difficulty and time of rescue will increase sharply; 3. During the rescue process, it is very likely that the ruins will collapse again and cause secondary injuries. While the rescuers are safe, it also reduces the efficiency of rescue

The rescue tools corresponding to this rescue method are mainly excavation devices, excavation machinery, and pneumatic or hydraulic support machinery. Although these machinery can provide assistance to rescue work to a certain extent, they cannot penetrate into people in a short time. Rescue the people trapped in landslides as early as possible, and these construction machinery are large in size, and the movements during work are too large, which can easily cause secondary landslides in the already unstable ruins, which will seriously affect the lives of the trapped people. security poses a threat
