Description

Technical Field

[0001] The utility model relates to the technical field of cable installation, and more specifically, to a combined ladder-type cable bridge. Background Art

[0002] Cables can transmit electricity and are an important component of power equipment. When installing cables at high places, cable trays are often used to support the cables and ensure the normal operation of the cables.

[0003] Most common cable trays are assembled from multiple parts. When assembling, each part is often fixed and installed by bolts, but the installation of bolts requires the use of additional tools, and a fixed structure often requires multiple fixing bolts. Therefore, faced with a large number of parts combinations, the bolt-fixed installation method is cumbersome, which is not conducive to the workers' assembly of the cable tray, and the work efficiency is low; moreover, the general cable tray has a simple structure, with only a supporting structure, and its upper part is open and lacks protection. Under long-term work, dust and rain are easy to affect the cables; in addition, common cable trays only have supporting capabilities and can support cables, but cannot fix the position of cables. In strong winds or other working environments that require contact with cables, cables are easy to swing. The swinging of longer cables will cause certain destructive force, which is not conducive to the stable operation of the cables. Utility Model Content
