Lightweight local follow-up safety lifesaving protection device for mining ores in mountain

Abstract

The invention discloses a lightweight local follow-up safety lifesaving protection device for mining ores in a mountain, and belongs to the technical field of ore extraction. The safety lifesaving protection device comprises a dynamic balance anti-bumping damping type movable bearing mechanism, a gear engaging transmission type height adjusting mechanism, an electrorheological state change type protective enclosure body, a soft woven transverse displacement type local assault contraction protective ceiling, a microwave activation type air purification safety protection mechanism and a multi-layer material supply station. The lightweight local follow-up safety lifesaving protection device for mining the ores in the mountain creatively applies a local quality principle to the technical field of ore extraction, and according to the contradictory technical problems that a protection device needs to be good in protection performance, applicability and universality and cannot be too heavy, the contradictory technical problem that the mass of a traditional protection device can be increased due to the applicability and the universality under different effects under the condition that no induction recognition element exists is solved.

Description

technical field [0001] The invention belongs to the technical field of ore mining protection, and specifically refers to a light-weight partial follow-up type safety life-saving protection device for ore mining in a mountain. Background technique [0002] Mine is a place for mining ore or producing mineral raw materials. Mining is a high-risk industry, and safety production must be paid attention to. The annual incidence of mine accidents in my country is relatively high. It is difficult to rescue the victims in the event of a safety accident in a mine, and it is easy to cause casualties. Casualties, safety accidents in mines are mainly due to loosening of mining holes, collapse, improper operation or natural causes of mine collapses. Therefore, mining companies are generally equipped with corresponding life-saving protective devices to ensure the personal safety of mining personnel to a certain extent. . [0003] However, the traditional mine safety lifesaving protection dev...

Problems solved by technology

[0003] However, the traditional mine safety lifesaving protection device has single function and weak anti-smashing performance. In the event of a landslide accident, it is difficult to guarantee the endurance limit of the lifesaving device, which will cause the lifesaving device to be damaged by the ore, resulting in the personal safety of mining personnel. Secondly, due to the irregular shape of the ore itself, the height of the mine is inconsistent during mining, but the height of the existing life-saving protection device for ore mining cannot be flexibly adjusted according to the height of the mine, resulting in existing life-saving The use of protective devices is limited. If the height of the mine is low, the life-saving protective device cannot pass through, which is extremely poor in practicability; thirdly, the ore mining terrain in the mine is relatively complicated and uneven, which makes it difficult for the life-saving protective device to travel. Especially when passing through the ground with a large height difference, it is very easy to roll over, further reducing the safety of the protective device; in addition, when encountering landslides or falling gravel, it is easy to cause dust to fly, and can float on the ground for a long time. In the air, after the formation of many dusts, the surface can often absorb other gaseous or liquid harmful substances and become the carrier of other harmful substances. When mining personnel inhale the air containing dust, the inhaled dust particles will After passing through the trachea, main bronchi, and bronchiole, it enters the respiratory bronchioles, alveolar ducts, and alveoli in the gas exchange area, and produces toxic effects during the entry process, affecting the gas exchange function. The dust particles themselves contain soluble substances or are in the air. According to the different solubility, other harmful substances adsorbed in the air can dissolve in the mucus in the respiratory tract or alveoli, and be absorbed by the human body to directly cause poisoning. The existing life-saving protective devices for mining cannot purify the air in the mine, threatening Safety of Mining Workers' Lives
