井下救生舱密封装置设计
Design of Sealing Device for Lifeboat in Underground Mine

随着我国煤矿产业的快速发展，煤矿安全也逐渐成为人们不可忽视的一环。而井下救生舱，作为一个在发生矿难后为无法及时撤离，为矿工提供安全、密闭空间的救生装备，要求不仅能够良好地抵御爆炸冲击的性能，还要具备隔绝有毒有害气体的密封性。井下救生舱的出现，极大地提高了井下工作人员的安全性，同时大大减少了财物的损失。本文分析了在救生舱密封装置设计时应该注意的问题，特别设计了救生舱舱门的气动原理和密封舱门结构，对舱门机构进行了运动分析，并对舱门的密封进行了设计和计算。
With the rapid development of China’s coal mining industry, coal mine safety has gradually become an indispensable aspect. The underground survival capsule, as a life-saving equipment that provides a safe, airtight space for miners who cannot evacuate in time after a mine disaster, requires not only the ability to withstand explosive shocks but also the sealing property to isolate toxic and harmful gases. The emergence of underground survival capsules has greatly improved the safety of underground workers and significantly reduced property losses. This article analyzes the issues that should be considered in the design of the survival capsule’s sealing device, especially the design of the pneumatic principles and sealing structure of the capsule door, conducts a kinematic analysis of the door mechanism, and designs and calculates the sealing of the door.
