Abstract

一种平衡型塔架式抽油机，在上平台（11）上面活动连接一驱动平台（10），电动机（13）、减速箱（25）及驱动轮（15）都设置在驱动平台（10）上，驱动平台（10）下面设一调重箱（12），天轮轴（20）上设一被动轮（27），驱动绳（23）固定在驱动轮（15）上，并且驱动绳（23）的两端分别与被动轮（27）固定相连。通过调节调重箱（12）的重量，使抽油机正常运行时，驱动轮（15）两边驱动绳（23）的驱动力的差接近1/2油柱重量，则整机上的抽油杆牵引绳（17）和配重箱牵引绳（24）的牵引力差减小，这时驱动绳（23）克服了一部分摩擦力而工作，因此产生节能效果，减少抽油机磨损，延长抽油机使用寿命。

Description

平衡型塔架式抽油机
本申请要求于2016年1月22日提交中国专利局、申请号为201610042539.2、发明名称为“平衡型塔架式抽油机”的中国专利申请的优先权，同时要求于2016年1月22日提交中国专利局、申请号为201620062674.9、发明名称为“平衡型塔架式抽油机”的中国专利申请的优先权，两者的全部内容通过引用结合在本申请中。
技术领域
本发明涉及一种采油机械，尤其是涉及一种节能型塔架式抽油机。
背景技术
在能源紧缺，电力严重不足的情况下，节能成为很重要的议题。抽油机是油田主要生产设备，对于低渗透率油田，油位形成比较慢，大部分抽油机很长时间都在空转中，这将浪费大量电能，并造成抽油机磨损，降低抽油机寿命。
目前，常用的塔架式抽油机相对于常规游梁式抽油机比较节能，但节能效果还远远达不到国家节能要求。塔架式抽油机其驱动部分固定在框架上，当配重箱的重量设置到抽油杆重量加上1/2油柱重量时，无论抽油杆上升或者下降时，抽油杆牵引绳和配重箱牵引绳的牵引力始终相差1/2油柱重量，因此两边始终不能平衡，耗能大，与国家节能要求相距甚远，抽油机磨损增加，降低抽油机寿命。
发明内容
本发明所要解决的技术问题是现有抽油机耗能大、磨损严重、寿命低的问题，从而提供一种平衡型塔架式抽油机。
为解决上述技术问题，本发明提供一种平衡型塔架式抽油机，主要包括底座、框架、配重箱、抽油杆、抽油管、电控柜、电动机、减速箱、驱动轮、导向轮、天轮，框架设在底座上，框架上面设有上平台，电动机与减速箱及驱动轮依次传动连接，其特征在于：上平台上面活动连接一驱动 平台，电动机、减速箱及驱动轮都设置在驱动平台上，驱动平台下面设一调重箱，天轮轴上设一被动轮，驱动绳固定在驱动轮上，并且驱动绳的两端分别与被动轮固定相连。
驱动平台下面通过两个轴承座安装一铰链轴，铰链轴的两端固定在上平台上的轴瓦固定器上。
驱动平台连接在上平台上面且远离驱动轮的一端，调重箱设置在驱动平台下面位于驱动轮一端。
驱动轮两边驱动绳的驱动力差为1/2油柱重量。
本发明通过调节调重箱的重量，使抽油机正常运行时，驱动平台绕铰链轴转动，驱动轮两边的驱动绳的驱动力存在差值，则整机上的抽油杆牵引绳和配重箱牵引绳的牵引力差相应减小，这时驱动绳克服了一部分摩擦力而工作，因此产生节能效果，减少抽油机磨损，延长抽油机使用寿命。当驱动力差为1/2油柱重量时，抽油杆牵引绳和配重箱牵引绳的牵引力相等，达到平衡，节能效果最佳。
附图说明
图1是本发明结构示意图；
图2是图1的左视图。
图中：抽油管1、抽油杆2、底座3、框架4、配重箱5、悬绳器6、轴瓦固定器7、铰链轴8、轴承座9、驱动平台10、上平台11、调重箱12、电动机13、减速箱输出轴14、驱动轮15、导向轮架16、抽油杆牵引绳17、导向轮轴18、导向轮19、天轮轴20、天轮21、天轮支架22、驱动绳23、配重箱牵引绳24、减速箱25、电控柜26、被动轮27。
具体实施方式
