Description

一机多井抽油机 本申请要求于 2010 年 12 月 30 日提交中国专利局、 申请号为 201020697251.7、 发明名称为 "一机多井抽油机"的中国专利申请的优先权， 其全部内容通过引用结合在本申请中。 技术领域
本发明涉及一种釆油装置， 尤其是涉及一种一机多井抽油机。

目前， 国内外双井抽油机在开发和应用中均存在一机双井传动机构可 靠性差、 作业移机让位困难、 不能实现一井修井作业而另一井正常抽油生 产以及也无法同时实现双井平衡调节的问题。
发明内容
本发明的目的是提供一种一机多井抽油机， 不仅平衡精度高， 而且某 一口井修井， 其它井也能正常釆油。
为了实现上述目的， 本发明提供一种一机多井抽油机， 包括天轮、 支 承架、 导向轮、 导向轮架、 驱动轮、 驱动轮架、 驱动绳、 抽油杆、 油杆牵 引绳、 配重、 配重牵引绳、 传感器、 节能用配重、 动力装置、 电控拒， 支 承架顶部安装天轮，导向轮安装在导向轮架上，驱动轮安装在驱动轮架上， 驱动绳缠绕在驱动轮上， 驱动绳的两端分别连接到天轮轮周的前、 后两侧 上， 各井的抽油杆都通过悬绳器和油杆牵引绳分别经过导向轮也连接到天 轮轮周的前、 后两侧上， 挂了配重的两个配重牵引绳也分别连接到天轮轮 周的前、 后两侧上， 节能用配重对应于相应的抽油杆位置在天轮轮周内固 定。
天轮在每一个工作循环中其旋转角度小于 200° 。
一个循环天轮转 180。 时， A抽油杆在井口位置， 节能用配重在天轮 右侧的水平位置， 当完成一个冲程时， 节能用配重在天轮左侧水平位置。
所述的动力装置包括电动机、 小链轮、 大链轮、 链条、 其中所述电动 机输出轴上安装有小链轮， 所述的驱动轮轴上安装有大链轮， 所述的链条 连接小链轮和大链轮。
电动机和传感器及制动器都与电控拒相连， 而且电控拒是用电子遥控 器远程控制， 所以该设备的操作是很安全的。
本发明是以一机带 A、 B两口井， 当动力装置带动驱动轮旋转时， 驱 动绳就带动天轮旋转， 如果天轮旋转方向是顺时针时 A井抽油， B井的抽 油杆和油柱的重量是当配重的 , 相反天轮按逆时针方向旋转时 B井抽油 , A井的抽油杆和油柱重量是当配重的。 如果 B井的井深或泵径大， 则 B配 重箱里多加相应的配重块就两边还可保持较高的平衡精度。
如果对 B井进行修井时， 把 B井上边的 B导向轮和 B油杆牵引绳拿 掉后在 A配重箱里装满相应的配重块， 则 A井还可以正常抽油。
在上例中看到一机带两口井抽油， 同样以对称的方式一机对四口井、 六口井、 8口井一样抽油。
附图说明
图 1是本发明的结构示意图；
图 2是图 1的左视图。
具体实施方式
参照图 1、 图 2, 本发明包括 A井 1、 驱动轮架 2、 制动器 3、 小链轮
4、 电动机 5、 链条 6、 驱动轮 7、 大链轮 8、 A抽油杆 9、 A悬绳器 10、 A 导向轮架 11、 B配重箱 12、 B配重牵引绳 13、 A导向轮 14、 驱动绳 15、 A油杆牵引绳 16、 天轮 17、 支承架 18、 B油杆牵引绳 19、 A配重牵引绳 20、 A配重箱 21、 B导向轮 22、 传感器 23、 节能用配重 24、 B导向轮架 25、 B悬绳器 26、 B抽油杆 27、 电控拒 28、 B井 29、 支 架 18的顶部安 装天轮 17、 A导向轮 14安装在 A导向轮架 11上， B导向轮 22安装在 B 导向轮架 25上， 驱动轮 7安装在驱动轮架 2上， 驱动绳 15缠绕在驱动轮 7上， 动力装置包括电动机 5、 小链轮 4、 链条 6、 大链轮 8, 电动机 5输 出轴上安装小链轮 4,驱动轮 Ί上安装大链轮 8、链条 6连接小链轮 4和大 链轮 8。
电动机 5和传感器 23、 制动器 3与电控拒 28相连， 而且电控拒是用 电子遥控器远程控制， 所以该设备的操作是很安全的。
A井 1的 A抽油杆 9通过 A悬绳器 10与 A油杆牵引绳 16相连， B井 29的 B抽油杆 27通过 B悬绳器 26与 B油杆牵引绳 19相连， A油杆牵引 绳 16和 B油杆牵引绳 19又分别与天轮 17轮周的前、 后两侧相连， A配 重箱 21通过 A配重牵引绳 20连接到天轮 17轮周上挂 B配重箱 12—侧， 而 B配重箱 12通过 B配重牵引绳 13连接到天轮 17轮周上挂 A配重箱 21 一侧， 驱动轮 7上缠绕的驱动绳 15的两端也分别与天轮 17轮周的两侧相 连， 因此当电动机旋转时带动小链轮 4和链条 6及大链轮 8旋转， 从而带 动驱动轮 7转动， 则带动驱动绳 15使天轮 17旋转，这样随着天轮 17把 A 油杆牵引绳 16和 B油杆牵引绳 19带着各自的抽油杆上、 下往复运动， 实 现抽油， 当天轮 17的旋转方向是顺时针时是 A井抽油， 而 B井的抽油杆 和油柱的重量是当配重， 相反天轮 17的旋转方向是逆时针时 B井抽油， 而 A井的抽油^^和油柱的重量当配重。
如果 B井比 A井深而且泵径也大时， 则往 B配重箱 12里多装相应重 量的配重块就仍然保持较高的平衡， 从而达到节能的目的。
如果对 B井进行修井时， 把 B井上边的 B导向轮 22和 B油杆牵引绳 19拿掉后， 在 A配重箱 21里装满相应的配重块， 则 A井可以正常抽油。
本发明一机带 A、 B两口井抽油， 同样以对称的方式对四口井、 六口 井、 八口井也都能一机带动。
天轮 17的轮周内按着抽油杆位置所相应的位置安装了节能用配重 24, 例如一个循环天轮转 180° 时， A抽油杆到达井口， 节能用配重在天轮右 侧的水平位置； 当完成一个冲程时， 节能用配重到达天轮左侧水平位置。 节能用配重 24其空间位置不同， 对天轮 17轴产生的扭矩不同， 利用这个 原理调节好其节能用配重的重量， 就能获得较好的无耗能启动和制动的效 果， 其节能效果显著， 为此天轮 17 在每一个工作循环中旋转角度不大于 200° 为好。
