Abstract

本实用新型是为石油钻井工程中，鼠洞管内钻具上扣和卸扣而设计的一种卡紧装置。它是利用鼠洞管内钻具自重，使装置的翻板卡紧机构下移收缩，并借助于方钻杆旋转时的动力使颚板内滚子爬坡卡紧钻具。在鼠洞管内用大钳紧扣时能代替背钳。

Description

本发明属于石油钻井机械中钻具的上、卸扣工具，主要用于卡紧在鼠洞管内的钻具，使其上端钻具能迅速、简便地完成上、卸扣工作。
现有的无动力鼠洞管钻具卡紧装置有翻板式手动卡紧装置，它是由手动旋转－偏心牙板来实现卡紧钻具的，适用于小扭矩上扣，但在大扭矩紧扣时易使卡紧机构损坏。另一种是螺旋轨道下移卡紧装置，体积较庞大、结构复杂。以上两种装置只有一个旋向的卡紧功能，而另一旋向不能卡紧钻具，这是这类卡紧装置的不足之处。
本发明的任务是提供一种无动力、较简单的鼠洞管卡紧装置，它能承受钻具上、卸扣反扭矩，代替背钳。并能在左、右两个旋向卡紧钻具。
本发明的特征是：翻板卡紧机构的翻板（5）上带有弧形坡道C，颚板（5c）上带有弧形坡道B。C、B坡道相互对应，两个坡道之间装有圆柱形自由滚子（5a）。见附图（一）（二）
利用钻具接头座在悬挂勾（3）上时的钻具自重，使翻板卡紧机构（5）与浮动体（4）同时下移，则由于壳体（2）上的斜面A的作用，能使颚板（5c）向中心收缩，预先卡紧钻具。在钻具上扣或卸扣时所具有的旋转力的作用下，使装有弹性芯轴（5b）的自由滚子（5a）在弧形坡道B和C之间爬坡，从而进一步卡紧钻具。
具体实施方法：将翻板卡紧机构（5）掀开，放入钻具，当钻具下端接头通过卡紧装置后，合上翻板卡紧机构（5），使钻杆上端接头座在悬挂钩（3）上，当方钻杆接头与其鼠洞管内的钻杆接头对准扣，转动方钻杆上或卸扣时将鼠洞管内的钻杆卡住。当钻杆由鼠洞管内提起时，由于重力撤去，在弹簧（1）的作用下，翻板卡紧机构（5）及浮动体（4）同时向上运动，自动解脱卡紧力。钻杆提出鼠洞管卡紧装置时，钻杆下端接头的台阶将翻板卡紧机构（5）顶开，悬挂勾（3）回缩，为下一根钻杆放入作好准备。
