Abstract

Узел срезных плашек, содержащий верхний и нижний плашечные блоки, содержащие лезвия, расположенные на противоположных сторонах от трубы и других более гибких предметов и выполненные с возможностью обхвата и срезания указанной трубы и более гибких предметов. Узел срезных плашек содержит направляющие трубу рычаги, которые прикреплены к верхнему плашечному блоку, предназначены для направления трубы и других предметов в канал, образованный указанными лезвиями, и выполнены с возможностью прохождения в выемки нижнего плашечного блока. Узел срезных плашек также содержит износные накладки, установленные сверху на направляющих рычагах и расположенные с возможностью воздействия на нижний плашечный блок для его поднятия, когда указанные рычаги проходят в указанные выемки, таким образом обеспечивая уменьшение зазора между указанными лезвиями так, чтобы лезвия могли лучше срезать более гибкие предметы.Shear ram assembly containing upper and lower ram blocks containing blades located on opposite sides of the pipe and other more flexible objects and made with the possibility of wrapping and cutting said pipe and more flexible objects. The shear ram assembly comprises pipe guiding levers, which are attached to the upper ram block, are designed to guide the pipe and other objects into the channel formed by said blades, and are configured to pass into the recesses of the lower ram block. The shear ram assembly also includes wear pads mounted on top of the guide arms and positioned to act on the lower ram block to raise it when said arms pass into said recesses, thereby reducing the clearance between said blades so that the blades can better cut more flexible items.
