Abstract

本发明公开了一种用于钻井泵的驱动单元的扭矩保险装置。源自钻井泵和/或驱动单元的过载能够完全被至少一个键状的保险元件接收和/或抵消。

Description

模块式的扭矩保险装置
技术领域
本发明涉及一种用于钻井泵的驱动器的扭矩保险装置。
背景技术
专利文献DD245931A1公开了一种用于传递扭矩到驱动轴上的键连接，它具有对受驱动的元件的轴向保险装置。受驱动的元件、尤其是呈携动件的形式被切缝并且它的轴向保险通过借助夹紧螺栓的夹紧实现。受驱动的元件的用于将受驱动的元件夹紧在驱动轴上的缝槽对应键的宽度。在安装受驱动的元件时，键被这样地接收，即在受驱动的元件被夹紧之后，它形状锁合地与键的侧面形成作用连接。
德国专利文献DE19748907C1公开了一种用于可旋转驱动的导杆的驱动头，尤其是用于驱动钻井泵。在具有用于导杆的穿孔的壳体中支承一个可旋转驱动的套筒，该套筒包围导杆的一个区段并且通过联轴器与导杆连接。为了受控地减少存储在导杆中的扭转能量设置一个返回制动器，它具有一个可通过套筒驱动的转子和一个支撑在壳体上的定子。定子通过保险装置防止相对壳体转动，只有当导杆基本上没有扭转能量时，保险装置才可松开。因此允许无危险地检查，扭转能量是否已被减少。
由现有技术已知很多装置和方法，通过它们能够驱动和/或固定钻井泵。首先，抵抗通过通过导杆的扭转产生的扭矩引起的过载的保险装置在此始终带来问题。扭转能量能够这样地产生大的转速，使得驱动器通过驱动轮和皮带这样地被加速，以至于驱动器被破坏。在最坏的情况中，驱动轮的旋转速度这么大，使得它在皮带断裂之后这么强劲地加速，以至于它不能承受该负载并且破裂。通过飞过来的驱动轮部分可能导致严重的伤害。由于任务错综复杂，在市场上有不同的装置。
发明内容
因此，本发明的任务是，提供一种装置，在用于钻井泵的驱动轴中通过该装置可经济地且可靠地避免由扭转能量和/或由过高的驱动能量产生的扭矩引起的过载。
以上任务通过用于过载保险装置解决，该过载保险装置包括权利要求1的特征。其它有利的设计方案由从属权利要求的特征得出。
本发明的另一个任务是提供一种方法，在用于钻井泵的驱动轴中通过该方法能可靠且不复杂地避免过载，尤其是由扭转能量和/或由过高的驱动能量产生的扭矩引起的过载。
该任务通过一种包括权利要求6的特征的方法解决。
已经公开一种用于钻井泵的驱动单元的扭矩保险装置。源自钻井泵和/或驱动单元的过载能够完全被至少一个键状的保险元件接收和/或抵消。通过使用按照本发明的保险元件保护输送设备的最薄弱的部件免受过大的扭矩。所述至少一个保险元件是一个专用键。
所述至少一个保险元件由一种材料、优选由两种材料制成。所述保险元件的至少两种材料以分层方式和/或以一种均质混合物的方式和/或以一种通过网或层强化的均质混合物的方式存在。通过所述保险元件的设计可限定在驱动系统和/或钻井泵损坏之前允许接收的最大剪切力。
所述至少一个保险元件设置在轴套中。该轴套被这样地设置，使得它完全地包围空心轴并且在空心轴和驱动轮之间建立作用连接。保险元件同时安放在轴套的第一槽和空心轴的第二槽中。保险元件通过保持装置固定在这两个槽中，该保持装置通过至少两个螺栓稳固。
此外公开了一种用于使用按照本发明的装置的方法。在此不仅当在空心轴上出现过载时而且当在驱动轮上出现过载时沿着剪切线剪切该一个或多个保险元件。按照本发明的保险元件由一种材料、优选由两种不同的材料制成。此外可以通过所述至少一个保险元件的不同尺寸和不同材料组合能够接收和/或抵消不同大小的扭矩。
附图说明
下面应当根据附图详细说明本发明的实施例及其优点。各个元件在图中相对彼此的尺寸比例不是始终符合真实的尺寸比例，因为一些形状被简化，而另一些形状出于清楚的考虑相对于其它元件放大地被示出。
图1示出了按照本发明的装置在驱动单元中的布置。
图2以三维视图示出了按照本发明的装置的示意结构。
图3示出了保险元件的一种优选实施方式。
图4示出了如何通过保险元件在该装置和驱动单元之间建立作用关系。
具体实施方式
图1示出了按照本发明的、在驱动单元10中的装置20。通过该装置20阻止从驱动轮12传递到空心轴16上或从空心轴传递到驱动轮上的过载。当钻井泵(未示出)被闭锁时，该过载可以通过驱动马达(未示出)的过大的力产生。另一个干扰可能性可以是通过存储在驱动系统中的扭转能量产生的过载。当驱动器失效并且预设的反冲制动器不能正常工作或完全失效时，扭转能量冲击式释放。为了避免这一点，该装置20在驱动轮12的区域中设置在空心轴16上。该装置20被这样地安装，使得保险元件24位于驱动轮12上方。由此得到对于螺栓28的可实现性，保险元件24通过该螺栓固定。因为保险元件24在过高的扭矩时、即在过载时被剪断，所以迅速更换是必须的，以便能够快速地重新着手运行。这通过该装置20的布置得到。抛光杆14穿过空心轴16延伸，钻井泵通过该抛光杆驱动。
图2以三维视图示出了按照本发明的装置20的示意视图。该装置20基本上由一个轴套22组成，驱动轮(未示出)被推套到该轴套上。在轴套22中存在第一槽30，保险元件24被安放在该第一槽中。保险元件24通过保持装置26固定并且通过螺母28稳固。
图3示出了保险元件24的一种优选实施方式。该保险元件24由第一材料34和第二材料36构成。显然，保险元件24也可以由均质的材料制成，所述至少两种材料在该均质的材料中相互混合。由现有技术已知很多可能性，用于连接两种材料、使其稳定并且形成希望的形状。在这里示出的优选实施方式因此不是对保护范围的封闭性地限制。此外在理想化地示出的位置上可看到剪切线40。当出现过载时，保险元件24沿着该剪切线40被剪切。
图4示出了如何通过保险元件24在该装置20和驱动单元之间建立作用关系。保险元件24配合到轴套22的第一槽30和空心轴16的第二槽32中。通过所述作用关系在正常运行中确保扭矩传递。在可能导致钻井泵和/或驱动单元损坏的过高扭矩的情况下，保险元件24优选沿着剪切线40被剪断并且因此能够实现各个旋转部件的无损坏的空转。保险元件24通过保持装置26稳固，保持装置通过螺栓28与轴套22连接。
本发明已经参照一种优选实施方式被说明。
