Description

液压缓冲滚轮罐耳
技术领域
本发明涉及一种用于矿井提升容器的导向与缓冲装置,具体是一种液压缓冲滚轮罐耳,当提升容器在提升过程中发生横向摆动,撞击罐道时,该装置能减缓或消除这种摆动,使提升容器平稳运行,保障提升容器的运行安全,广泛应用于煤矿冶金矿山的提升系统中,属于矿山机械领域。
背景技术
目前在煤矿冶金矿山行业,矿井生产提升系统为了消除提升容器在运行过程中产生的摆动,常在提升容器上安装滚轮罐耳,它采用弹簧或橡胶或油缸作为缓冲件,液压型滚轮罐耳(如液压自适应滚轮罐耳ZL 2019 2 0753785.8,液压缓冲型滚轮罐耳CN201711147453.7)是对弹簧型滚轮罐耳产品的一个重大的进步,但这种新型产品存在着体积较大,零部件较多,结构复杂,对每台产品的连通管需要分别设计,并且加工制作成本较高,至今没有很好的解决办法。
发明内容
本发明的目的是为了克服上述现有技术的不足之处,提供一种液压缓冲滚轮罐耳,它主要由滚轮、支架、底座、缓冲油缸组成,缓冲油缸内采用双腔结构,由活塞与内套组成甲腔,活塞与滑套、缸盖组成乙腔,甲腔和乙腔之间由活塞槽连通,当滚轮受撞击时,活塞向下移动压缩甲腔油液进入乙腔,实现缓冲。
本发明是以如下技术方案实现的:一种液压缓冲滚轮罐耳,其特征是:缓冲油缸含有缸筒,缸筒的内环面紧贴滑套的外面,滑套上面有上弹簧,上弹簧固定在缸盖上,滑套下面有下弹簧,下弹簧固定于缸座上,滑套的内面紧贴内套的外面,内套固定于缸座上,缸座上开有油孔,内套的内面紧贴活塞,活塞的底面和内套的内面及缸座组成甲腔,活塞和内套、滑套、缸筒、缸盖组成乙腔,甲腔和乙腔通过活塞槽互通。
所述的活塞槽采用变截面V形槽。
所述的上弹簧、滑套、下弹簧、活塞及甲腔乙腔的液压油组成罐道变形适应系统。
本发明的有益效果是:该液压缓冲滚轮罐耳结构简单紧凑,所需零件少,容易制造,易于实现批量标准化生产,大大降低生产成本,缓冲力的大小取决于活塞槽的截面积,缓冲力从从几十公斤到几吨都很容易设计,可以把缓冲件做得很小,不再担心提升容器布置空间的限制,在罐道变形的情况下,也可以适应罐道变化而紧贴罐道,从双油缸及连通管路系统的缓冲改为单油缸内部双腔缓冲,是对液压缓冲滚轮罐耳的一种简化,同样能达到现有的液压滚轮罐耳的缓冲效果。
附图说明
下面结合附图及实施例对本发明作进一步详细说明:
图1是本发明的结构示意图:
图1中:1、滚轮,2、轮轴,3、支架,4、转轴,5、底座,6、上销轴,7、活塞,8、缸盖,9、上弹簧,10、活塞槽,11、缸筒,12、内套,13、滑套, 14、下弹簧,15、缸座,16、单向阀,17、下销轴,18、缓冲油缸,19、甲腔, 20、乙腔。
具体实施方式
如图1所示:一种液压缓冲滚轮罐耳,滚轮1通过轮轴2和支架3相连,支架3通过转轴4和底座5相连,底座5通过下销轴17和缸座15连接,支架3 和活塞7通过上销轴6相连。
所述的缸筒11的内环面紧贴滑套13,滑套13上部有上弹簧9,上弹簧9 固定在缸盖8上,滑套13下有下弹簧14,滑套13的内面紧贴内套12,内套12 固定于缸座15上,缸座15上开有油孔,油孔末端有单向阀16,内套12的内面紧贴活塞7,活塞7的底面和内套12的内面、缸座15组成甲腔19,活塞7和内套12、滑套13、缸筒11组成乙腔20,甲腔19和乙腔20通过活塞槽10互通。
所述的活塞槽10采用变截面V形槽。
所述的上弹簧9、滑套13、下弹簧14、活塞7及甲腔19乙腔20的液压油组成罐道变形适应系统。
工作过程:通过单向阀16向甲腔19注入液压油,液压油通过活塞槽10进入乙腔20,滑套13下移,甲腔19和乙腔20充满油液,滚轮1处于工作状态,关闭单向阀16,提升容器运行过程中,滚轮1受撞击后,所受力通过轮轴2使支架3绕转轴4转动,支架3通过上销轴6将力传给活塞7,活塞7向下运动,压缩甲腔19油液,通过活塞槽10进入乙腔20,此过程中实现缓冲,乙腔20油液推动滑套13向下滑动,下弹簧14被压缩,缓冲过程停止后,下弹簧14推动滑套13上移,乙腔20油液回流,活塞7恢复到初始位置,等待下次缓冲。
