Description

Technical Field

[0001] This utility model belongs to the field of cutting technology, specifically relating to a cable protection pipe cutting device. Background Technology

[0002] Power cable protection pipes are made primarily of modified polypropylene. They are characterized by high temperature resistance and external pressure resistance, making them suitable for high-voltage power transmission cable ducts of 10KV and above. Using modified polypropylene as the main raw material eliminates the need for extensive dredging and road surface damage, allowing for the laying of pipelines and cables in special locations such as roads, railways, buildings, and riverbeds. Compared to the traditional trenching method, trenchless power pipe engineering is more environmentally friendly, eliminating the dust, traffic congestion, and other disturbances caused by traditional construction. This technology can also be used to lay pipelines in areas where excavation is not feasible, such as historical sites, urban areas, crop and farmland protection zones, highways, and rivers. However, while a limiting structure is needed to precisely measure the length during cutting, the resulting constraint after cutting makes removal difficult and cumbersome. Summary of the Invention
