Downhole life-saving equipment

Abstract

The invention discloses downhole life-saving equipment. The downhole life-saving equipment comprises a ground hoisting crane and an underground life preserver which is connected with the ground hoisting crane. The underground life preserver comprises a clamp-type stretching control X frame, a hanging bracket, a bottomed self-control device, a bottomless telescopic barrel and a bottomed clamp device. The clamp-type stretching control X frame is formed by hinging two mechanical arms in a crossed mode. The top of the hanging bracket is hinged to the upper portion of the clamp-type stretching control X frame through a connecting rod. The lower portion of the hanging bracket is hinged to the crossed position of the two mechanical arms. The bottomed self-control device is located below the clamp-type stretching control X frame and is further hinged to the lower ends of the two mechanical arms. The lower ends of the two mechanical arms are further fixedly connected with the bottomless telescopic barrel. The upper portion of the bottomless telescopic barrel is connected with the bottomed self-control device, and the bottom of the bottomless telescopic barrel is fixedly connected with the top of the bottomed clamp device. The life-saving equipment is wide in life-saving range, efficiency can be improved and cost can be reduced; the life-saving difficulties are lowered, and the burdens of firemen are relieved; original manual operation is changed into automation at one step, rescue can be conducted immediately when the equipment comes, the rescue does not have to depend on fire brigades, and local people can carry out rescue in time.

Description

technical field [0001] The invention relates to underground rescue equipment, in particular to an underground lifesaving equipment. Background technique [0002] The underground lifesaving device in the prior art has the following problems: 1. Deep wells are mostly located in rural fields, and the best golden time for lifesaving is missed due to the time delay caused by receiving the police and driving into the rescue. 2. Existing life preservers are large in size, heavy in weight, incomplete in function, and are manually operated, so rescue must rely on the fire brigade, making it difficult to save people and even more difficult to quickly locate them. 3. Machine calibration requires the joint efforts of many people, which is cumbersome to operate, high in cost, and time-consuming. 4. There are many rescuers and the area is large. The key is that it cannot be located at one time, and it will not be able to save a life and save a family in time, which brings helplessness to...

Problems solved by technology

[0002] The underground lifesaving devices in the prior art have the following problems: 1. Most of the deep wells are located in rural fields, and the best golden time for life-saving is missed due to the time delay caused by receiving the police and driving into the rescue.

2. Existing life preservers are large in size, heavy in weight, incomplete in function, and are manually operated. Rescue must rely on the fire brigade. It is difficult to save people, and it is even more difficult to locate quickly

3. Machine calibration requires the joint efforts of many people, which is cumbersome to operate, high in cost, time-consuming and labor-intensive

4. There are many rescuers and the area is large. The key is that it cannot be located at one time, and it will not be able to save a life and save a family in time, which brings helplessness to the firefighters. And put an unnecessary burden on the fire brigade
