Size-adjustable pipeline leveling device

The utility model discloses a size-adjustable pipeline leveling device, and aims to solve the technical problem that a clamping mechanism of a pipeline leveling device in the prior art can only clamp a pipeline with a specific size, so that the use of the device has great limitation. The pipeline leveling device comprises a support, a fixed clamping mechanism and a movable supporting plate, the fixed clamping mechanism is installed on the upper surface of the support, a supporting base is arranged on the upper surface of the support, and the movable supporting plate is installed on the upper surface of the supporting base through a lifting mechanism; the upper surface of the movable supporting plate is connected with a supporting rod. According to the pipeline leveling device, firstly, the end of a pipeline is erected on the upper surface of the movable supporting plate, then a threaded rod is rotated to drive an extrusion plate to move downwards through a bearing, the pipeline can be clamped when the extrusi
