Trenchless pipeline deformation device

Technical Field

The utility model relates to a pipeline warp technical field, specifically is a non-excavation pipeline warp device.

Background

In the prior art, in the trenchless restoration construction process of the pipeline, in order to smoothly pass through a new lining pipe with the same diameter when the lining pipe passes through an underground old pipeline, the new lining pipe needs to be deformed to reduce the overall diameter after deformation so as to pass through the old pipeline to be restored, the process part currently adopts a deforming machine, and the deforming machine adopts five groups of deformation guide wheels to gradually deform the plastic lining pipeline from an O shape to a U shape.

The deformation machine adopts five groups of deformation guide wheels for changing an O-shaped pipeline into a U shape, each group of the deformation guide wheels gradually deforms the O-shaped pipeline to finally realize a complete U-shaped pipeline, but the deformation machine adopting the mode has a complex structure, heavy weight and large volume, and an operator must be in close contact with the pipeline to operate due to the fact that the deformation machine consists of five groups of the guide wheels, so that industrial accidents occur, and certain hidden dangers are caused to the safety of constructors.
