Pipe coupler for earth drill pipe, has transverse element provided at pipe filling end, where longitudinal opening and transverse recess are provided at pipe filling end, and transverse bar exhibits geometrical form |
摘要 |
<p>The coupler has a transverse element (1) provided at a pipe filling end. A longitudinal opening and a transverse recess are provided at the pipe filling end. The transverse element is designed as T or L-shaped transverse bar. The longitudinal opening is designed in an L-shape. The transverse bar exhibits a geometrical form, which causes a longitudinal locking of the transverse bar after pivoting into the transverse recess in a working position. A locking device consists of a mounting recess. An independent claim is also included for a method for coupling a set of pipe sections.</p> |
