Description

Technical Field

[0001] The utility model relates to the technical field of large-diameter cable curvature production, in particular to a large-diameter cable curvature production pipe bender. Background Art

[0002] A cable is a conductor used to transmit power, communication signals or data, usually consisting of one or more insulated conductors.

[0003] In the construction of cable laying projects, large-diameter cable laying and wiring are often involved. Generally, two workers assist in bending the cable radius. When encountering cables with a diameter of more than 240mm, the construction technology is relatively backward and the bending radius does not meet the requirements, resulting in cable back-changing. The bending deformation causes external force to damage the connecting cables. The bending is not enough and the cover plates at the elbows of some bridges cannot cover them firmly. The bending does not meet the aesthetic requirements of the cable layout. There are also safety hazards and low work efficiency. The flatness, straightness and bending radius of the overall cable layout are required to be high, especially in the construction environment where there is insufficient space and large cables are connected in the distribution box. The workers' arm strength is completely insufficient to meet the requirements, so it needs to be improved. Utility Model Content
