Description

Technical Field

[0002] Before cable tightening, it is necessary to ensure that the civil engineering has been completed, such as the reserved holes and embedded parts have been firmly installed according to the design requirements, the floor and plastering work of the cable trench, tunnel, shaft, etc. has been completed, and the cable trench has unobstructed drainage and no water accumulation. In addition, the templates and other facilities along the cable have been removed, the site has been cleaned, the roads are unobstructed, and the trench covers are complete. The scaffolding for laying cables has been erected and meets safety requirements, and the lighting illumination along the cable meets the construction requirements. When tightening the cables, it is necessary to pay attention to avoid mechanical damage to the cables, such as avoiding the cables from being pinched or cut during the tightening process. At the same time, it should be ensured that the quality of the tightening materials and tools meets the requirements, and the use of inferior materials should be avoided, resulting in loose cable tightening. In addition, construction workers should wear appropriate protective equipment, such as insulating gloves and hard hats, to ensure construction safety. Cable tightening refers to the use of various tools and materials to bundle double or multiple rows of cables into bundles during the cable laying process to keep the cables neat and orderly. This not only helps to improve the aesthetics of the cables, but also reduces friction between the cables and prevents damage to the cables due to looseness. After the current cable is tightened, if a certain section of the cable needs to be further adjusted after maintenance, the existing tightening device cannot adjust the direct gap after tightening the double-row cables. Therefore, a cable tightening device for installing double-row cables is needed. Summary of the invention
