Description

Technical Field

[0001] The utility model relates to the technical field of trough type cable bridges, in particular to a light and high-strength trough type cable bridge. Background Art

[0002] Trough type cable tray, also known as trough type cable tray, has a certain depth and closure. Compared with other types of cable trays, trough type cable tray has the advantages of protecting cables, high strength, good stability, suitable for dense wiring, easy installation, etc. Therefore, it is widely used in laying computer cables, communication cables, thermocouple cables and other control cables of highly sensitive systems. It has good effects on shielding interference of control cables and protection of cables in heavy corrosion environments, but it still has the following disadvantages in actual use.

[0003] In Chinese patent CN202321787006.9, the utility model discloses a light and high-strength trough-type cable tray, which relates to the field of cable laying technology. The utility model includes a trough-type cable tray body and a cable support plate, a dust cover plate is plugged into the inner side of the trough-type cable tray body, and multiple cable support plates are plugged into the inner side of the trough-type cable tray body from top to bottom, a dust cover plate is attached to the upper side of a cable support plate, multiple heat dissipation holes are opened on both sides of the cable support plate, multiple shock-absorbing components are clamped on both sides of the cable support plate, and a dust-proof partition is plugged into the bottom side of one cable support plate. The utility model solves the problem that the trough-type cable tray dissipates heat through the heat dissipation holes through the trough-type cable tray body and the cable support plate, but it is easy to cause dust to accumulate in the dead corners between dense cables, and the cables are usually not cleaned of dust after laying, and long-term use will shorten the service life of the cables. When the trough-type cable tray carries a large number of cables, it is difficult to take into account the problems of light weight and high strength.

[0004] Most of the existing trough-type cable trays are square. During actual use, dust will enter the inside of the trough-type cable tray through the heat dissipation holes with the flow of air. There are many dead corners between dense cables, which are easy to accumulate dust, causing the cables to accumulate heat more easily. The slow air flow makes it difficult to blow away the dust in the dead corners. The cables are usually not cleaned of dust after laying. Long-term use will shorten the service life of the cables. When connecting the bridges, someone needs to assist when connecting with bolts, and it is not easy to align the threaded holes, which increases the difficulty of installation.

[0005] Therefore, in order to solve the above problems, a lightweight and high-strength trough-type cable tray is proposed. Utility Model Content
