Description

Technical Field

[0001] The utility model relates to the technical field of cable laying, in particular to a traction device for cable laying. Background Art

[0002] Cable laying is a crucial task in the power, communications, and infrastructure construction sectors, directly impacting the operational efficiency and safety of the entire system. Traditional cable laying methods, whether relying on manual dragging or simple mechanical assistance, are inefficient and prone to errors. Manual dragging is not only labor-intensive but also difficult to ensure the smoothness and stability of the cable lay, prone to problems such as winding and entanglement, seriously affecting project progress and quality. While simple mechanical assistance improves efficiency to a certain extent, it often lacks flexibility in cable clamping, has poor adaptability, and struggles to handle cables of varying diameters and models.

[0003] In order to solve the above problems, a number of cable traction devices have appeared on the market. These devices have improved the laying efficiency and reduced manpower requirements to a certain extent. However, the existing devices generally have the problem of inflexibility and poor adaptability in cable winding and clamping methods. Most devices can only handle cables of specific specifications, which limits the scope of use of the equipment. In addition, the existing traction devices often find it difficult to ensure the uniform and stable laying of cables during the traction process, and are prone to problems such as uneven cable tension and deviation of the laying path from the predetermined trajectory. Staff still need to frequently intervene to make adjustments, and true fully automated and efficient laying cannot be achieved. Therefore, in response to the above technical problems, a traction device for cable laying is proposed herein. Utility Model Content
