Title: (EN) Apparatus and method for separating flanges
(ZH) 分离凸缘的设备和方法
Abstract: front page image
(EN) The present invention provides a method and apparatus for separating or spreading flanges (70) of pipes typically comprising two bolt hole engaging devices (20) and a force transmission system. The force transmission system is arranged for selective coupling with the or each bolt hole engaging device (20) and capable of exerting a force thereon for selective movement of the flanges (70) relative to one another in order to separate the pipes. The bolt hole engaging device (20) comprises an expandable member (40) that is arranged to be at least partially accommodated within the bolt hole before expansion. The bolt hole engaging device (20) also comprises an expander means (38, 54), arranged to expand the expandable member (40) such that at least a portion of an outer surface of the expandable member (40) is expanded to contact the bolt hole. The expander means (38, 54) can comprise at least one wedge shaped member and an actuator means for causing relative movement between the wedge shaped member and the expandable member (40) to cause the expandable member (40) to expand. The expansion of an expandable member (40) within a bolt hole maintains a large surface area of the bolt hole engaging device (20) in contact with the bolt hole and thereby increases the friction between the device (20) and the flanges (70) to be spread, resulting in a more reliable apparatus.

本发明提供分离或展开管道的凸缘(70)的方法和设备,所述设备通常包括两个螺栓孔接合器件(20)和力传输系统。这种力传输系统设置用于与这个螺栓孔接合器件(20)或每个螺栓孔接合器件(20)选择性耦合并能够在这些螺栓孔接合器件上施加力,以选择性地使这些凸缘(70)相对于彼此移动,以将管道分离。螺栓孔接合器件(20)包括可张开构件(40),这种可张开构件(40)设置成在张开之前至少部分地容纳在螺栓孔内。螺栓孔接合器件(20)还包括张开装置(38、54),张开装置(38、54)设置成将可张开构件(40)张开,以将可张开构件(40)的外表面的至少一部分张开以与螺栓孔接触。张开装置(38、54)可包括至少一个截头圆锥体部分和致动装置,该致动装置用于引起该截头圆锥体部分与可张开构件(40)之间的相对移动,以使可张开构件(40)张开。可张开构件(40)在螺栓孔内的张开保持与螺栓孔接触的螺栓孔接合器件(20)的大的表面积,并因此增加了这些器件(20)与要展开的这些凸缘(70)之间的摩擦力,这样就产生了一种更加可靠的设备。
