CRASH RESISTANT TRIP FOR A PIPE MACHINING APPARATUS

摘要

A pipe machining apparatus includes a frame, a tool support, an advancement device, and an advancement member. The tool support is coupled to and movable relative to the frame. The tool support is adapted to support a tool and move the tool in a direction toward a pipe at an increment. The advancement device includes an advancement projection fixedly attached to the frame. The advancement projection includes a contact-surface. The advancement member is coupled to the tool support. Upon the advancement member contacting the contact-surface of the advancement projection the advancement member is adapted to advance the tool towards the pipe at the increment. The contact-surface of the advancement projection is shaped to always be in a non-perpendicular contact position with the advancement member.
