Abstract
A mobile pipe welding machine includes a welding unit for welding pipes and a pipe receiver for guiding a pipe to the welding unit. The pipe receiver has a distal end facing away from the welding unit and a proximal end facing towards the welding unit. On the distal end there is at least one linearly movable contact body for lifting the pipe.
Claims19
A mobile pipe welding machine, comprising:
- a welding unit for welding pipes;
- a pipe receiver for guiding a pipe to the welding unit,
- wherein the pipe receiver comprises
- (i) a distal end facing away from the welding unit, and
- (ii) a proximal end facing the welding unit;
- at least one linearly movable contact body for lifting the pipe positioned at the distal end of the piper receiver;
- at least one contact body drive configured to move the at least one contact body along a linear path from a neutral position, in which the at least one contact body does not lift the pipe, and into a lifting position, in which the at least one contact body lifts the pipe;
- and
- a run-up skid which
- is proximally in a longitudinal direction in relation to the longitudinal axis of the pipe receiver behind a distal end of the at least one contact body in the neutral position, and
- has a run-up surface that extends transverse to a horizontal plane.

A mobile pipe welding machine, comprising:
- a welding unit for welding pipes;
- and
- a pipe receiver for guiding a pipe to the welding unit,
- wherein the pipe receiver comprises
- a distal end facing away from the welding unit, and
- a proximal end facing the welding unit, wherein the pipe receiver comprises at the distal end at least one linearly movable contact body for lifting the pipe,
- wherein the at least one linearly moveable contact body has a base body, which is guided on the contact body longitudinal guide and is fixed to a scratch protection made of an anti-scratch material, and
- wherein the based body is made of a base body material, and wherein a base body material hardness of the base body material is at least five times a Vickers hardness of the anti-scratch material and/or at least ten times a Shore D hardness of the base body material hardness.
