Description

Technical Field

[0001] The utility model relates to the technical field of cable bridges, in particular to a cable bridge with automatic clamping and positioning functions. Background Art

[0002] Cable trays are widely used in petroleum, chemical, electric power, light industry, telecommunications and other industries. They are mainly used for the laying of overhead power cables, control cables, lighting lines, and telecommunications cables. Cable trays are divided into trough-type cable trays, tray-type cable trays, ladder-type cable trays, grid trays and other structures, and are composed of brackets, supports and installation accessories.

[0003] When cable trays are used for laying cables, they are generally placed directly on the inside of the tray. The lack of clamping and limiting components makes the cables easy to loosen during laying, which is not conducive to the protection of the cables. At the same time, the cables are directly laid on the inside of the tray, and the friction between the cables and the tray is large, resulting in poor safety protection effect. There are certain defects and shortcomings, so improvements are needed. Utility Model Content
