Description

用于螺纹接头冲击松脱的方法和设备
技术领域
螺纹接头冲击松脱的检测
本发明涉及一种在岩石钻孔时检测螺纹接头冲击松脱的方法和设备。
背景技术
当在地面例如岩石中钻深孔时，在钻孔的过程中，为了如所需要的那样延长钻柱，多个钻杆被螺纹连接在一起使用。螺纹的束紧通常由于在钻孔过程中穿过螺纹接头的冲击波而变得很紧固，以至于一个人不可能仅在钻岩机的旋转马达的帮助下松脱螺纹接头。为了解决这一问题，操作者通过使冲击装置向钻柱施加短时间的冲击力，而在不向地面挤压钻柱的前提下，中止钻孔。操作者在听到声音特征改变时止动冲击装置。此后，可通过钻岩机的旋转马达旋松钻柱，并且分离的钻杆可被一个接一个地提起。这种方法的缺点是当钻孔自动地进行时，一个人不能完成钻柱的自动化收取。另一个缺点是操作者由于这种噪音环境，听到初期阶段发生的冲击松脱有困难。这导致了钻孔设备的不必要的磨损。
发明内容
限定在随后的权利要求中的本发明，旨在完成对螺纹接头冲击松脱的检测，以便在其本身的钻孔后，使自动化钻孔，包括自动化收取钻柱成为可能，从而在这之后一个人即可定位用于钻新孔的钻孔设备。本发明的另一个目的在于通过对螺纹接头冲击松脱的早期检测，来避免在钻孔上施加不必要的载荷。这主要通过当钻岩机冲击钻柱而不向地面输送钻柱时，检测钻孔设备发出的振动来实现。该检测可通过使用扩音器或用于其它频率的振动传感器来完成。在分析工具中将所检测到的振动与已知的用于冲击松脱的振动模型特征相比较。这些振动模型可以是来自钻孔设备的振动特征的变化，或是冲击松脱后得到的特征形状的振动。当分析工具检测到冲击松脱已经发生时，信号被发送至钻孔装置的控制系统，该控制系统关闭冲击装置，并在这之后，钻柱以一根钻杆接一根钻杆的形式被自动收取。
附图说明
图1显示了结合有本发明特征的钻岩机设备。
具体实施方式
下面将参照附图描述本发明的实施例，该附图示意性示出了包括本发明的钻岩机设备。
示于附图的钻岩机设备包括设置有悬臂12的运输车11，在该悬臂上设置有输送杆6。钻岩机2可沿该输送杆往复移动。钻岩机2包括用于向钻柱1施加冲击力的冲击装置和常规的旋转装置。钻柱1可包括任意数量的通过螺纹接头相互连接的钻杆。扩音器或其它振动检测装置7设置在输送杆6上，或位于其它适当的位置。装置7连接至分析工具4，该分析工具4适宜地包括滤波器，以便分离引人关注的频率而用于频率分析，并减少待处理的数据量。分析工具4可被设置为数字式工作或模拟式工作。在分析工具4中，将所检测到的振动与已知的振动模型相比较，该已知的振动模型可以是振动特征的典型变化，或者是对螺纹接头冲击松脱的典型振动模型的新发现。当检测到冲击松脱时，信号被发送至钻孔设备的控制系统5，随后该控制系统关闭冲击装置。此后，钻柱1可被自动收取，并且其可以钻杆接钻杆的形式被置于棒料送进器13中。
示于附图的钻孔设备可用于地表。本发明可同样用于钻地下的深孔，例如用于灌浆方面。
