摘要： Linear pipe recovery/lay tensioners can include one or more pivot assemblies for rotatably moving an upper track away from a lower track to facilitate placement of a pipe segment between the two tracks. In addition, or alternatively, the tensioners can include one or more hydraulic cylinders that provide flexible suspension to the upper and lower tracks so the tracks can move and rotate as necessary due to differing pipe segment shapes. In addition, or alternatively, the upper and lower tracks include one or more gripping pads having one or more gripping members that can be sheathed by a compliant member until such time as the pipe segment compresses the compliant member causing the gripping member(s) to protrude from the compliant member and engage the pipe segment. Rotation of the tracks is controlled by a hydraulic pump capable of rotating the tracks at the same rate or at different rates.
摘要翻译： 线性回收/放置张紧器可以包括一个或多个枢轴组件，用于将上轨道可旋转地移动远离下轨道，以便于将管段放置在两个轨道之间。 另外或可替代地，张紧器可以包括一个或多个液压缸，其向上和下轨道提供柔性悬挂，使得轨道可以由于不同的管段形状而必要地移动和旋转。 另外或替代地，上部和下部轨道包括一个或多个夹持垫，其具有一个或多个夹紧构件，该夹紧构件可以被柔顺构件包覆，直到管段压缩柔性构件使得夹紧构件 从顺从构件突出并与管段接合。 轨道的旋转由能够以相同速率或不同速率旋转轨道的液压泵来控制。
