Embodiment Construction

[0024] The following examples can enable those skilled in the art to understand the present invention more comprehensively, but do not limit the present invention in any way.

[0025] A method for fixing a stainless steel plate lining an underground rescue cabin. The method includes the following steps: after the cabin section of the rescue cabin is welded, a rigid fixing block 4 is welded at the bottom of the flange plate 2 on the end surface of the cabin section. The welding must be firm. Then lay the insulation layer. After the insulation layer is laid, the non-metallic fixed block 3 is fixed on the rigid fixed block 4 by screws. The material of the non-metallic fixed block 3 is a laminated glass cloth plate to reduce the heat transfer inside and outside the cabin during use. Save refrigerant. Then the connecting piece 5 is welded to the inner stainless steel plate 1, and finally the connecting piece 5 is fixed on the non-metallic fixing block 3 with screws, so as to realiz...

Abstract

The invention discloses a fixing method of an underground rescue capsule lining corrosion resistant plate, belonging to the technical fields of rescue capsule heat preservation and interior decoration. The method comprises the following steps of (1) welding a rigid fixing block at the position of a bottom of a flange on a cabin section end face after completion of welding of a cabin section of a rescue capsule; (2) laying a heat preservation layer; (3) fixing a non-metal fixing block on the rigid fixing block through a bolt after completion of laying of the heat preservation layer; (4) welding a connection piece on the lining corrosion resistant plate; and (5) fixing the connection piece on the non-metal fixing block by using the bolt to achieve fixing of the lining corrosion resistant plate. The fixing method of the underground rescue capsule lining corrosion resistant plate is simple, a surface of the cabin lining plate has no surplus matters, the surface is smooth and clean, the lining plate is convenient to fix, fine adjustment of positions can be achieved in a fixing process, assembly is simple, and simultaneously purposes of heat preservation and heat retaining of a cabin are achieved. The heat preservation layer can be easily changed after invalidation of the heat preservation layer. Installation cost and maintenance cost of the rescue capsule are reduced.

Description

technical field [0001] The invention belongs to the technical field of heat preservation and interior decoration of a rescue cabin, in particular to a method for fixing stainless steel plates lining an underground rescue cabin. Background technique [0002] 95% of my country's coal mines are underground coal mines, the production environment is relatively harsh, and mining accidents occur relatively frequently. It is urgent to quickly change the safety production status of the coal mine system and fundamentally reverse the passive situation of safety production. The rescue cabin is mainly placed near the coal mining working face and the main transportation roadway. When emergency accidents such as gas and coal dust explosions, roof collapses, etc. occur underground, and the underground environment is not suitable for miners to continue ascending the shaft to escape or temporarily unable to escape, they can quickly enter to avoid danger. The rescue cabin is a closed space com...
