Underground lifesaving apparatus

Abstract

The invention relates to a lifesaving device, in particular to an underground lifesaving apparatus used after a person falls into a well. The underground lifesaving apparatus comprises a pull rod and a support frame. The underground lifesaving apparatus is characterized in that the bottom end of the pull rod is provided with opposite circular arc sheets, the bottom ends of the circular arc sheets are provided with opposite insertion holes, the center of the support frame is connected with the circular arc sheets at the insertion holes by using a connector, the support frame is positioned between the two circular arc sheets, the lengths of the two circular arc sheets are 1 / 2 to 3 / 5 length of the support frame, and two ends of the support frame are connected with two ropes sleeved in the pull rod respectively; and a pull rod body is provided with two scattered pull rings, a safety belt is tied to the pull rings, and the pull rod has a hollow tube structure. The underground lifesaving apparatus has the advantages of strong practicability for saving persons in large shafts and small shafts due to folding or unfolding of the support frame, good safety and avoidance of re-fall of saved persons to the well.

Description

(1) Technical field [0001] The invention relates to a lifesaving device, in particular to an underground lifesaving device used when a person falls into a well. (2) Background technology [0002] When a person falls into the well, the existing life-saving devices mainly include: 1. Put a hanging basket down the well, let the person who fell into the well sit in the hanging basket, and hang the person out of the well through the hanging basket; 2. Put the ladder down the well, Let the people in the well climb out of the well along the ladder; 3. The lifeguards are tied with straps, put the lifeguards into the well with a sling, and the lifesavers hug the person who fell into the well and hang them out of the well with the sling. The deficiencies that the above-mentioned lifesaving device and mode exist in use are: (1) applicability is narrow, 1., when people fall into the less well of well shaft, then be difficult to come in handy, especially when the human body is stuck in t...

AI Technical Summary

Problems solved by technology

The deficiencies in the use of the above-mentioned lifesaving device and method are: (1) narrow applicability, 1., when a person falls into a well with a small shaft, it is difficult to use it, especially when the human body is stuck in the shaft.

(2) The safety factor is not high

Both the hanging basket and the way of holding people have the possibility of falling into the well due to reasons such as the hanging basket falling off and the person not holding the person tightly.
