Description

Technical Field

[0001] The utility model relates to the technical field of power pipeline processing, in particular to a power pipeline cutting device. Background Art

[0002] Power pipelines are products that are coated inside and outside with PE epoxy resin and are mainly used in power pipes and municipal communications.

[0003] In the prior art, the pipe cutting device is mainly composed of a base, a cutting mechanism and a clamp. During use, the pipe is first fixed to the base by the clamp, and then the cutting mechanism is started. Under the action of the hydraulic rod on the cutting mechanism, the cutting mechanism is pushed down, and then the cutting disc is driven to rotate by the driving motor to cut the pipe. The existing Chinese patent number CN220007986U discloses an electric pipe cutting device, which drives the clamping plate to move by rotating the screw, thereby increasing the clamping effect on pipes of different diameters. However, in the above device, when the pipe length is short but the cross-sectional area is large, if the area of ​​the cutting disc is smaller than the cross-sectional area of ​​the pipe, multiple cuts are required to cut the pipe. If the area of ​​the cutting disc needs to be larger than the cross-sectional area of ​​the pipe, the pipe can be cut at one time, and the use of a cutting disc with a larger area will cause a waste of resources.

[0004] Therefore, it is necessary to develop a power pipeline cutting device to address the above defects. Utility Model Content
