Aluminium-magnesium alloy cable bridge

Abstract

The invention discloses an aluminium-magnesium alloy cable bridge, and the cable bridge comprises a direct-connection bridge. The direct-connection bridge consists of a bottom plate, side plates, and a cover plate. The two sides of the bottom plate are respectively provided with one side plate, and the top of the bottom plate is provided with the cover plate. The tops of the side plates are provided with grooves, and the bottom of the cover plate is fixedly provided with an elastic hook part. The interior of the bottom plate and the side plates is provided with an anti-corrosion layer. According to the invention, the tops of the side plates are provided with grooves, and the bottom of the cover plate is fixedly provided with the elastic hook part. The bottom of the elastic hook part is elliptical, and is in buckled connection with the side edges of the grooves, thereby facilitating the splicing installation of the cover plate and the side plates, and improving the structural stability of the direct-connection bridge. The bottom plate, the side plates and the cover are respectively made of aluminium-magnesium alloy materials. Compared with a cable bridge made of stainless steel, the cable bridge provided by the invention greatly reduces the weight, and reduces the transportation cost. The interior of the bottom plate and the side plates is provided with the anti-corrosion layer, thereby improving the anti-corrosion performances of the direct-connection bridge, and prolonging the service life of the cable bridge.

Description

technical field [0001] The invention relates to a cable bridge, in particular to an aluminum-magnesium alloy cable bridge. Background technique [0002] The cable tray is divided into trough type, tray type, ladder type, grid type and other structures. It is composed of brackets, brackets and installation accessories. The bridges in buildings can be erected independently or attached to various buildings and pipe gallery brackets. In terms of structure, it should reflect the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts of the general cable tray need to be galvanized. The cable tray is a new type of cable laying device. The cable tray was originally invented for laying It is used when cables are used, and now it is not only used when laying cables, but also cable trays are used when laying and installing optical cables and pipelines.

[0002] The cable tray is divided into trough type, tray type, ladder type, grid type and other structures. It is composed of brackets, brackets and installation accessories. The bridges in buildings can be erected independently or attached to various buildings and pipe gallery brackets. In terms of structure, it should reflect the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts of the general cable tray need to be galvanized. The cable tray is a new type of cable laying device. The cable tray was originally invented for laying It is used when cables are used, and now it is not only used when laying cables, but also cable trays are used when laying and installing optical cables and pipelines. The bridges installed outside the building are usually used to supply power to factories or building facilities, and for The cable tray set up for communication is installed at the bottom of the ceiling of the building in a hanging manner. The function of the cable tray is mainly to support cables, protect cables and manage cables. The general cable tray is installed with screws. This way The quality requirements for the screws are very high, a large number of screws are required, the installation cost is high, and the installation method is inconvenient. The structural stability of the cable tray cannot be strictly guaranteed. The cable tray is easily corroded by rain after long-term use. It is easy to cause damage to the cables on the cable tray and cause cable equipment failure. Generally, the cable tray is made of stainless steel, which is heavy and the cost of transporting the cable tray is high.
