Description

Technical Field

[0001] The invention relates to the technical field of life-saving equipment, and in particular to an underground life-saving device. Background Art

[0002] Although modern society is developing rapidly and the pace of technological progress is getting faster and faster, there are still great deficiencies in rescue equipment for professional fields. For example, there are often some wells in farmland (a considerable part of which are unmanaged abandoned wells). In addition, even in wasteland, there are often some abandoned wells used for exploration but not landfilled. In television and news reports, there are often news of children falling into abandoned wells. These abandoned wells have great safety hazards. Once someone falls into them, the rescue process is very long. Especially for some working conditions with narrow wellheads, it is often necessary to use large equipment such as excavators to gradually dig underground from a position close to the wellhead. The excavation process must also ensure the safety of the trapped people. The difficulty of implementation and rescue is very great, the rescue efficiency is low, and it is difficult to gain precious rescue time. The trapped people in the well may be injured or physically exhausted, and their lives are in danger. Even if the rope is lowered, in most cases, it is difficult for the trapped people to have enough physical strength to be pulled to the wellhead. For ordinary rescue chairs and other equipment, it is easy to get stuck on the well wall, causing the trapped people to be suspended in mid-air. Such facilities are prone to cause secondary injuries to the trapped people. Especially when the trapped person loses his intuition, the existing life-saving devices are difficult to effectively rescue.

[0003] The patent with application number 201910043564.6 discloses an underground life-saving device, which can be quickly and smoothly lowered into the well during rescue, and the lifting frame status can be adjusted according to the actual working conditions. The on-site rescue plan is highly flexible in arrangement. However, the underground life-saving device does not take into account the possibility of a certain traction rope breakage during the underground rescue process, and at the same time, a smooth rescue cannot be guaranteed when the trapped persons are rescued. Summary of the invention

[0004] The purpose of the present invention is to provide an underground life-saving equipment to solve the following technical problems: (1) by installing a support platform just above the rescue wellhead, fixing four bases in pairs on the ground on both sides of the wellhead, turning on the electric hoist, and putting the life-saving tube into the well through the hook, the trapped person enters the life-saving tube, and then the telescopic cylinder piston rod on the two fixed bars pushes the push block upward, and the push block drives the guide pin to slide upward in the waist-shaped slide groove through two connecting plates, and then the first rotating block drives the second rotating block to rotate through the spring, and the rotating rod cooperates with the two side plates to drive the climbing crawler to contact the inner wall of the well, and the rear drive The motor drives one of the driving wheels to rotate through the commutator, and the two driving wheels cooperate to drive the climbing tracks to rotate. The three climbing tracks drive the life-saving tube to move upward, and the electric hoist pulls the life-saving tube upward. The life-saving tube finally rises to the wellhead position to complete the rescue, thereby solving the technical problems that the traction rope may break during the rescue of underground life-saving equipment in the prior art, and the traction of trapped persons is not stable and safe during the rescue; (2) through the inclined design of the two support columns at the bottom of the support plate, and the design of a connecting rod and a connecting beam between the two support columns, the firmness of the underground life-saving equipment in the prior art is effectively improved.
