An anti-explosion multi-bag airbag and truss structure joint sealing device and method

Abstract

The invention discloses an anti-explosion multi-capsule airbag and a truss structure combined airtight device and method. The device includes an anti-explosion multi-capsule airbag and a truss structure. It includes rectangular parallelepiped airbags and arched airbags. The rectangular parallelepiped airbags are arranged in the middle and lower part of the roadway, the arched airbags are arranged above the rectangular parallelepiped airbags, and the auxiliary airbags are arranged on both sides of the rectangular parallelepiped airbags; The arc-shaped adjustment structure that can be adjusted correspondingly due to the change of shape, the main rectangular frame structure is arranged in the middle and lower part of the roadway, and the arc-shaped adjustment structure is connected above the main rectangular frame structure; the main rectangular frame structure and the arc-shaped adjustment structure are composed of several A truss unit and / or a plurality of corner connectors are connected. In the present invention, the anti-explosion multi-capsule airbag has a truss structure at the rear and is combined with it to seal, so that the risk of airbag slippage is basically eliminated, and the damage of the airbag is effectively avoided.

Description

technical field [0001] The invention belongs to the field of mine fire disaster relief, and in particular relates to an anti-explosion multi-bag airbag and a truss structure combined sealing device and a method for using the combined sealing device. Background technique [0002] Underground coal mine fires not only burn equipment and resources, cause casualties in the workplace, but also induce gas explosions. The effectiveness of disaster relief measures and the speed of disaster relief operations are the keys to the success of fire relief. The rapid sealing technology of coal mine roadway is an effective means of fire development, suffocation and fire extinguishing, and it is widely used in the practice of coal mine fire disaster relief. [0003] However, the airtight construction will reduce the wind flow, and the gas concentration in the closed area will continue to rise, and the gas concentration will rise rapidly. Coupled with the fire source in the fire area, the risk...

Problems solved by technology

However, there will be problems such as difficult transportation, time-consuming and labor-intensive filling.

There are also some fast-sealing walls that use steel structures to build skeletons and fill lightweight materials to resist shock waves. For example, the Chinese utility model patent with application number CN2019208094823 discloses a fast-sealing device for mine catastrophe areas with impact resistance. The airtightness of the device adopts steel structure to enhance the strength of the airtight wall, and the filling material is light, but the steel structure is difficult to meet the cross-section of different roadways, and the actual size is required for production, which greatly delays the best time for airtightness of the fire zone. Moreover, the steel structure is bulky and heavy

From this point of view, airtight walls built quickly, whether it is a lightweight hinged structure or a steel structure, have certain advantages over building airtightness, but there are still disadvantages such as low efficiency and poor adaptability.
