Description

Technical Field

[0001] The utility model belongs to the field of cable hangers, and particularly relates to a reinforced cable hanger structure. Background Art

[0002] During the construction and building process of tunnels, it is usually necessary to lay cables in tunnels. For cable laying, common practices include setting cable trenches or arranging cable hangers. Among them, arranging cable hangers is a widely used practice.

[0003] When installing the existing cable hangers, it often requires drilling installation holes first and then installing chemical anchor bolts for fixation. At the same time, in actual settings, in order to ensure the support stability of cable laying, it is often necessary to preferably set the spacing of cable hangers longitudinally and not make the spacing between adjacent two cable hangers too large. For example, in actual settings, it is usually necessary to install a cable hanger every 0.8 meters. After completing the setting of the cable hangers, the cables are placed into the cable grooves of the cable hangers and fixed, thereby completing the cable laying.

[0004] The above setting form can meet the cable laying requirements in tunnels to a certain extent. However, the above installation method also has some room for optimization, which is mainly reflected in the following aspects: First, the small spacing of cable hangers leads to a large amount of cable hangers used and increased costs; Second, the cable groove of the existing cable hanger and the installation substrate are connected by welding fixation, which requires high welding technology, and there is even a risk of the cable groove falling off subsequently; In addition, the connection between the grounding hanging ring and the installation substrate also mostly uses a post-welding process, which also requires high welding technology and there are safety hazards in grounding.
