Abstract

一种用于石油油井抽油杆的防脱扣扶正器,它是集防脱扣、刮蜡、扶正功能于一体的新型抽油杆装置;主要由上接头、滚柱、尼龙扶正轮、下接头组成。其结构简单、制造容易;且三功能融为一体,大大降低了生产成本。

Description

防脱扣扶正器
本实用新型用于石油油井抽油杆的防脱扣、刮蜡、扶正,是将三功能融为一体的新型抽油杆装置。
在机械采油作业中,抽油杆在上下冲程交变载荷的作用下,以及井斜、蜡卡、遇阻条件下,会产生一定的扭矩,迫使杆柱转动,导致联结螺纹脱扣。以往采用防脱扣短节、刮蜡器和扶正短节来消除这些影响,但势必造成抽油杆柱系统结构复杂,因此,设计了防脱扣、刮蜡、扶正三功能融为一体的防脱扣扶正器。
本实用新型的目的是减少油井内的联结部件,简化抽油杆柱系统结构,从而,降低油井内的事故发生率。
图1是防脱扣扶正器的结构图,图2是滚柱部位剖面图。
图1中:1.上接头2.滚柱3.尼龙扶正轮4.下接头
如图所示:上接头(1)的上端为内螺纹,与抽油杆匹配,下端有两排能使滚柱(2)自由滚动的滚道。下接头(4)的上端同样有两排能使滚柱(2)自由滚动的滚道,因此,下接头(4)与上接头(1)通过滚道内的滚柱(2)联结成一对旋转副。利用这对旋转副,即可消除抽油杆的旋转扭矩,从而起到防止抽油杆脱扣的作用。下接头(4)的下端为外螺纹,与抽油杆接箍匹配。尼龙扶正轮(3)自由套装在下接头(4)的中部,且轮的外表面制有螺旋齿,在工作中起扶正和刮蜡作用。

Claims (3)

1,一种用于石油油井抽油杆的防脱扣扶正器,它是用两排滚柱将上接头和下接头联结成一对旋转副,下接头的中部自由套装着尼龙扶正轮,轮的外表面制有螺旋齿,其特征是有两排滚柱,一个外圆制有螺旋齿的尼龙轮。
2,根据权利要求书1所述的防脱扣扶正器,其特征是:有两排滚柱,安装在上接头和下接头相对应的滚道内。且滚柱能在滚道内自由滚动。
3,根据权利要求书1所述的防脱扣扶正器,其特征是:有一个外圆制有螺旋齿的尼龙轮,安装在下接头的中部,且尼龙轮能在下接头中部位置上左右旋转和上下窜动。
