Description

Technical Field

[0002] As one of the largest supporting industries in the national economy, power cable is an indispensable component of the power transmission and transformation equipment system and the foundation of various industries. It is widely used in large power stations and power transmission line processes, airports, subways, river crossings, sea crossings and other occasions. It is known as the "blood vessels" and "nerves" of the national economy and is closely related to the development of the national economy. With the continuous development of urbanization in my country, the power consumption and quality of urban electricity consumption have been continuously improved, and the medium-voltage power cable transmission network has developed rapidly.

[0003] At present, cables are generally transported in rolls. When they arrive at the site for installation, they need to be straightened from the roll to a straight state. Generally, a bracket is set up and a steel pipe is inserted in the middle of the cable reel. The cable head is pulled forward and the cable reel starts to rotate until all the cables are pulled out. In this method, the cable is in direct contact with the steel pipe, and there is direct sliding friction between the cable casing and the steel pipe. After rotating like this for a long time, irreversible wear will occur on the cable casing, causing some cables to become unusable. The local appearance may not be damaged, but after a period of use, damage will begin to appear, reducing the service life and creating a leakage risk. There is a huge safety hazard. In addition, due to the inconsistency of cable manufacturers, specifications, and diameters, the diameter and thickness of cable reels on the market are also different.

[0004] Therefore, the existing cable pay-off tool cannot adjust the diameter and thickness to adapt to cable reels of different specifications, thereby reducing the applicability of the cable pay-off rack, and it is not convenient to shield the cable from dust and rain. Utility Model Content
