摘要： A pipeline debris shearing device includes a forwardly positioned, self sharpening, wear compensating, diameter conforming elastomeric member that forms a peeling edge having a negative rake angle to peel away debris from the internal wall of a pipeline. The peeling edge is formed at the point of meeting between a concave-shaped, curved forward face surface and a substantially straight outer peripheral surface. Radial slots may be provided to lessen the force being exerted on the peeling edge and provide for bypass flow to carry away debris removed by the peeling edge. Spaced-apart narrow stripper teeth may be added to help in removing harder deposits of debris. The peeling edge may be arranged substantially perpendicular the central longitudinal axis of the pipeline pig or arranged oblique to it. Further, the peeling edge may spiral about at least a portion of the pipeline pig.

摘要翻译：管道碎片剪切装置包括向前定位的自磨损磨损补偿的直径一致的弹性构件，其形成具有负前角的剥离边缘，以从管道的内壁剥离碎屑。剥离边缘形成在凹形弯曲前表面和基本上直的外周表面之间的会合点处。可以提供径向槽以减轻施加在剥离边缘上的力，并提供旁路流以携带由剥离边缘去除的碎屑。可以加上间隔窄的剥离牙，以帮助去除较硬的碎片沉积物。剥离边缘可以布置成基本上垂直于管道猪的中心纵向轴线或倾斜布置。此外，剥离边缘可以围绕管道猪的至少一部分螺旋。
