Description

Technical Field

[0001] This utility model relates to the field of cable laying traction technology, and in particular to a cable laying traction device for cable laying. Background Technology

[0002] Cable laying traction devices are specialized equipment used for mechanized cable laying in power, communication and other engineering projects. They replace manual pulling with electric motors or hydraulic drives to achieve efficient and safe cable laying. The main types include wheeled, tracked and intelligent types, which are suitable for tunnels, pipe corridors and other scenarios. Their technological development is trending towards intelligence and lightweighting, which can significantly improve construction efficiency and reduce the risk of cable damage. They are key equipment for modern cable engineering.

[0003] The publication number CN221862325U discloses a cable laying traction device for cable laying. This cable laying traction device has a guide mechanism at the top of the vertical rod, which allows the distance between two guide plates to be adjusted according to the width of the cable, thereby improving the applicability of different devices. The bottom plate has a rotation adjustment mechanism at the top, which allows the cable traction direction to be directly adjusted without the need for workers to push the entire device to adjust its position, thus enabling the device to adjust its direction in narrow environments.

[0004] Traditional cable laying traction devices mainly rely on manual traction or simple mechanical devices, requiring multiple people to pull, which is slow and physically demanding. The tension controlled manually is unstable, which can easily lead to overstretching and damage to the cable or sudden loosening and rebound. It is also difficult to ensure the straightness of the cable, and serpentine bends are likely to occur after laying. The quality of cable laying is highly dependent on the experience of workers, and the degree of standardization is low. Existing traction devices cannot balance efficiency, safety and adaptability, which affects the laying progress. Utility Model Content
