Description

Technical Field

[0001] This utility model relates to the field of pipeline processing technology, specifically to a tail bracket for pipeline trenching. Background Technology

[0002] In pipeline engineering, it is often necessary to process annular grooves (such as rolled or cut grooves) at the ends of pipes to facilitate quick connections using appropriate clamps. This type of grooving is typically performed using pipe grooving machines or cutting machines. In practice, especially when processing longer pipes, the end of the pipe furthest from the grooving machine head (the tail end) may sway due to gravity or lack of effective support. This swaying leads to inaccurate groove positioning, uneven depth, and non-perpendicularity between the groove and the pipe axis, affecting the quality and sealing of subsequent connections. Furthermore, the swaying increases the load on the grooving machinery, accelerating equipment wear.

[0003] Based on this, this utility model designs a tail support for pipe trenching. Utility Model Content
