Abstract

一种油管保护器包括壳体和盖板,壳体内有蜗轮和蜗杆,蜗杆固定在壳体上,油管固接在蜗轮上,在抽油杆上有顶块和滑环,滑环和推杆相连接,在推杆和蜗杆间有离合器。本实用新型利用抽油杆柱系统自身上下运动的能量,带动推杆和离合器,使蜗杆单向转动,继而带动固接在蜗轮上的油管微微转动,避免油管与抽油杆局部的重复性磨损,延长油管的使用寿命。

Description

油管保护器
                     技术领域
本实用新型属石油机械领域,具体地说是一种减少油井油管磨损的油管保护器。
                     背景技术
有杆抽油时,抽油杆柱在油管柱内作往复运动,由于井筒形状、油管弹性伸缩、抽油杆柱的运动等因素,难免发生抽油杆接箍与油管内臂的摩擦,尤其是在斜井段或弯曲井段,磨损相当严重。因为抽油杆与油管摩擦运动的轨迹重复,会使油管的某些部位重复磨损,造成该处的油管破裂。
                     发明内容
本实用新型的目的是针对上述油管与抽油杆的磨损特点,设计出一种避免油管与抽油杆重复磨损,使油管的磨损均匀的油管保护器。
本实用新型的目的是这样实现的:本实用新型的油管保护器包括壳体和盖板,壳体内有蜗轮和蜗杆,蜗杆固定在壳体上,油管固接在蜗轮上,在抽油杆上有顶块和滑环,滑环和推杆相连接,在推杆和蜗杆间有离合器。
本实用新型利用抽油杆柱系统自身上下运动的能量,抽油杆上的顶块推动滑环,带动推杆和离合器,使蜗杆单向转动,继而带动固接在蜗轮上的油管微微转动,避免油管与抽油杆局部的重复性磨损,延长油管的使用寿命。
                     附图说明
图1为本实用新型的油管保护器的结构示意图。
图2为本实用新型的推杆、离合器、蜗轮和蜗杆的连接示意图。
                   具体实施方式
下面结合附图通过实施例对本实用新型作进一步说明:
如图1和图2所示,本实用新型的油管保护器包括壳体1和盖板2,壳体1内有蜗轮3和蜗杆10,蜗杆10固定在壳体1上,油管9用油管挂5固接在蜗轮3上,油管9和壳体1间有轴承4,在抽油杆6上有顶块7和滑环8,滑环8和推杆11相连接,在推杆11和蜗杆10间采用超越离合器12连接。
