矿用防爆型螺旋式喇叭嘴防松装置设计

Mine Explosion-proof Spiral Bell Mouth Anti-loose Device Design

针对当前矿用防爆开关螺旋式喇叭嘴易产生松动,导致失爆,而引发井下瓦斯爆炸的情况,提出了一种防松装置设计方案,有效地预防螺旋式喇叭嘴松动现象。经过实际应用,取得了良好的效果,并可推广到多种井下重要设备中。

Aiming at the situation that the current mining explosion-proof switch spiral horn is easy to loose,resulting in explosion,and causing underground gas explosion,a design scheme of the anti-loose device is proposed to effectively prevent the looseness of the spiral horn.After practical application,it has achieved good results and can be extended to a variety of important equipment in the underground.
