Description

一种防断脱悬绳器
技术领域
本实用新型涉及一种防断脱悬绳器,属于石油开采设备抽油机悬挂装置技术领域。
背景技术
抽油机进行抽油时,悬绳器上的方卡子卡住光杆,为单级悬挂由驴头带动做往复运动进行油井生产。由于方卡子对光杆易造成伤害,经常在应力集中处(方卡子下面)发生断脱,光杆断脱造成杆柱落井撞击油管断脱,造成井下事故,导致油井停产和井口跑油污染环境。
发明内容
本实用新型的目的是克服现有技术中的断脱光杆落井造成井下事故,导致油井停产和井口跑油污染环境的缺陷,提供一种防断脱悬绳器。
本实用新型由悬绳上盘、连接螺栓、悬挂下盘组成,悬绳上盘和悬挂下盘均设有中空孔,悬绳上盘悬挂在毛辫子上,通过连接螺栓将悬挂下盘与悬绳上盘连接。
本实用新型可实现两级悬挂,有效防止光杆断后落井造成杆柱撞击油管等井下事故的发生,同时,解决了光杆断后,井口跑油污染环境的问题。
附图说明
附图1是本实用新型结构示意图。
图中:1、悬绳上盘,2、连接螺栓,3、悬挂下盘。
具体实施方式
由附图1可知,由悬绳上盘1、连接螺栓2、悬挂下盘3组成,悬绳上盘1和悬挂下盘3均设有中空孔,悬绳上盘1悬挂在毛辫子上,通过连接螺栓2将悬挂下盘3和悬绳上盘1连接。
将光杆穿过悬绳上盘1和悬挂下盘3的中空孔后,在悬绳上盘1上面有一方卡子固定在光杆上;悬挂下盘3上与悬绳上盘1之间的光杆上打方卡子,实现两级悬挂,该处的方卡子在抽油机工作时不受力。当光杆断时,因悬绳上盘1悬挂在毛辫子上,连接螺栓2连接悬绳上盘1和悬挂下盘3,悬挂下盘3上面的方卡子坐在悬挂下盘3上面,从而避免断脱光杆落入井内事故的发生,达到不停井生产的目的。
