Description

提拉式气体间隔器 技术领域
本发明涉及一种露天中深孔或井下VCR爆破中实现气体间隔装药的器械,具体地说是一种提拉式气体间隔器。
背景技术
在矿山开采、土石方工程等爆破作业中所使用的爆破孔气体间隔器一般有两种结构,一种是孔外开启阀门的气体间隔器,这种产品所用气雾罐的阀门放气速度慢,装药等待时间比较长,影响爆破孔装药作业的工作效率;另一种是孔内开启阀门的气体间隔器,这种产品目前还不够完善,因而不能用于小孔径(如Φ90mm)的爆破孔,而且这种气体间隔器在运输和使用过程中,还容易出现气雾阀门意外开启的现象,使产品失效,造成不必要的损失。
发明内容
本发明的目的就是提供一种提拉式气体间隔器,以解决现有气体间隔器存在的放气速度慢、装药等待时间长和投放位置不准等问题。
本发明是这样实现的:一种提拉式气体间隔器,在气袋中装有气雾罐,在所述气袋的外部接有吊绳,在所述气雾罐的底部接有配重物。
本发明通过在气雾罐的底部加装配重物,增加了气雾罐和本气体间隔器的整体重量。使用时,打开安全带,放开吊绳,先将本气体间隔器准确吊放到爆破孔内的预定深度,将孔口外的绳子在脚上缠绕2—3圈,然后在爆破孔的孔口外部将吊绳上提升1到2米,之后再迅速坠下,这样就可使本气体间隔器形成下冲态势,在到达预定深度的位置后,气体间隔器受吊绳长度所限而突然停顿,气雾罐上的阀门依靠气雾罐以及其中的液化气体和附加的配重的综合惯性力的作用而被打开,使罐内液体快速喷出并气化,气袋得以迅速膨胀,撑紧在爆破孔的内壁上,由此实现了气体间隔器在爆破孔内的准确投放和爆炮孔的间隔装药作业。
所述配重物是在盒体中装有重物,所述盒体的上口连接在所述气雾罐的底部。
所述配重物是在塑料袋中装有重物,塑料袋的上部粘接在所述气雾罐的下部或底部。
在所述气袋的上沿熔接有吊杆,所述吊杆的上部与所述吊绳的下端相接,所述吊杆的下部通过挂绳与所述气雾罐相连接。采用这种结构,气雾罐以及气雾罐上的阀门控制机构都被封装在气袋中,吊绳不与气雾罐上的阀门控制机构直接相连,静拉吊绳不会打开气雾阀门,由此避免了在使用过程中因意外操作而导致的产品失效。
所述挂绳的下端连接在所述气雾罐的控制杆上。
所述气袋是由内袋和外袋套接组成的双层密封袋,以提高产品可靠性。
在所述气袋的外部套有编织袋,以保护双层密封袋,防止划破。
在所述气袋和所述编织袋卷装后的外部束有将所述气雾罐上端顶紧在气袋上部的安全带。这样就可避免在产品运输过程中因野蛮装卸所致的气雾阀门意外开启的情况发生,防止产品失效。
所述吊绳上标有吊绳长度,这样就可将吊绳兼作为测量绳尺使用,从而将本气体间隔器准确地吊放到爆破孔内的预定深度。
本发明可以被投放到爆破孔内的任意预定位置,并在预定位置处将气雾阀门打开,实现快速充气,由此提高了气体间隔器投放位置的准确度,缩短了装药等待时间。本发明中的气雾阀门的开启动作可靠,可降低产品的失效和报废率,降低生产成本。合理地使用本产品,一方面可以在不影响爆破效果的前提下节省炸药使用量,降低采矿及土石方工程的生产成本;另一方面可以减轻由于爆破所带来的爆破冲击震动,减轻对地面建筑物的震动损害程度。
附图说明
图1是本发明的结构示意图。
图2是本发明卷装时的外观示意图。
具体实施方式
如图1所示,本气体间隔器的气袋是由内袋3和外带4套接组成的双层塑料密封袋。在气袋中装有气雾罐5。气雾罐5为气体间隔器专用气雾罐,可采用CN200920254180.0号公开的专利气雾罐。在气雾罐5的底部连接有配重物。该配重物是在一个上开口的筒状盒体6中装有沙子、石子或碎铁块等重物,盒体6的上口通过螺口或其他连接方式固定连接在气雾罐5的底部。
在气袋的上沿固定有吊杆2。吊杆的中部制有一个圆基片,用以热熔连接气袋的双层袋体。吊杆2的上部连接吊绳1,吊杆2的下部连接挂绳10,挂绳10的下端与气雾罐5的压杆8相连接。上拉压杆8,即可使气雾罐5上的气雾阀门9开启。
吊绳1是一种有长度标记的绳索。长度标记的设置,可以是在每米处标注对应的米数。这样,在向爆破孔中投放本气体间隔器时,就可做到准确投放。
为提高气袋的防护性,本气体间隔器在气袋的外部套有编织袋11,并且,在将编织袋11与气袋一道卷装在一起后,将内装的气雾罐上推,使气雾罐的上端顶紧在气袋的上沿,之后,在卷装的编织袋11的外部、相对气雾罐的底部边缘处束紧一条安全带12(图2所示),以防止气雾罐的松脱,由此避免了在运输和准备使用的过程中,本气体间隔器因气雾罐的滑动所导致的意外失效情况的发生。
本发明的使用方法是,先将捆扎在本气体间隔器外部的安全带12打开,再用吊绳将本气体间隔器先行下放到爆破孔内预定的深度,将在爆破孔孔口外露部分的吊绳在投放者的脚脖子上缠绕2—3圈并踩住绳头,向上提拉起孔内部分的吊绳1.5—2米,松手后迅速下放吊绳,气雾罐5与外包的气袋一起呈自由落体状下落,直到被吊绳拉住时,气雾罐5上的气雾阀门9依靠惯性作用被打开,罐内的液体迅速喷出并气化,气袋迅速膨胀,撑在预定的爆炮孔深度位置处,由此实现了对爆破孔的气体间隔,实现了在爆炮孔内的间隔装药作业。
