Closed-loop type mine-used lifesaving cabin body

Abstract

The invention discloses a closed-loop type mine-used lifesaving cabin body. The closed-loop type mine-used lifesaving cabin body is composed of a plurality of cabin body units in a combined mode end to end, wherein each cabin body unit comprises an inverted-U-shaped cabin body shell and a cabin body bottom shell which is used in cooperation with the cabin body shell, the two ends of each cabin body unit are provided with a cabin body connecting flange I and a cabin body connecting flange II respectively, the cabin body units are fixedly connected through cooperation between the cabin body connecting flanges I and the cabin body connecting flanges II, a plurality of horizontal plane closed-loop type reinforcing ribs are arranged on the two sides and the end faces of the interior of the lifesaving cabin body and are arranged in the cabin body direction, a plurality of vertical plane closed-loop type reinforcing ribs in the cabin body direction and a plurality of annular reinforcing ribs parallel to the cabin body connecting flanges I are arranged on the top surface, the bottom surface and the end faces of the lifesaving cabin body, and the reinforcing ribs in the three directions are staggered to form a closed-loop type reinforcing rib grid structure. According to the closed-loop type mine-used lifesaving cabin body, due to the fact that the reinforcing ribs are of a closed-loop and grid structure, stress is effectively dispersed, and antiknock performance is improved; due to the fact that the structure with the split units is adopted, movement and exchange of the closed-loop type mine-used lifesaving cabin body are convenient, and construction and transport are convenient.

Description

technical field [0001] The invention belongs to the technical field of mine safety equipment and relates to a cabin structure of a mine rescue cabin. It adopts a closed-loop rib grid structure, a fast positioning structure for connecting flanges and an arrangement of internal and external connecting bolts. The rescue cabin body is easy to disassemble and assemble underground, the stress is distributed evenly, and the anti-knock ability is strong. Background technique [0002] The rescue cabin is an emergency shelter for those in distress who cannot safely evacuate to the ground when a sudden disaster occurs underground. Its main function is to resist the impact of explosions, high-temperature smoke, roof collapse, and to isolate the intrusion of toxic and harmful gases, and keep the cabin absolutely airtight; internally, it can provide life-sustaining guarantees such as oxygen, food, and water for trapped miners, and provide external Rescue buys time. When a mine disaster...

Problems solved by technology

[0003] The structure of the existing rescue cabin is too complicated, the anti-knock ability is poor, the material waste is more, and the underground transportation is inconvenient

In addition, the underground conditions of coal mines in China are different. Some mines have narrow roadways. The traditional underground installation method of the rescue cabin cannot be accurately positioned, which affects the installation accuracy, and even cannot be installed.

Seriously affect the assemblability and assembly efficiency of the underground rescue chamber
