Description

Technical Field

[0001] The utility model relates to the technical field of cable bridges, in particular to a steel cable bridge structure. Background Art

[0002] Steel cable tray is a structural system used to support and protect cables. The main part of the cable tray is usually divided into two categories according to its shape and structure: tray type and ladder type. The tray type cable tray consists of a bottom plate and side plates to form a rigid trough-shaped component for directly supporting the cable load. The ladder type cable tray consists of side plates and several cross bars to form a trapezoidal component with a certain rigidity. The main body of the steel cable tray is usually made of steel, so it has good strength and stability and can bear the load of a large number of cables, ensuring the stability and safety of the cable system. In addition, steel has high fire resistance and can prevent the spread of fire in the event of a fire, protecting the cables from direct damage by heat and flames. Steel cable tray is widely used in construction, industry, municipal administration and other fields.

[0003] Steel structure cable trays are widely used in some factories. During the use of cables, a certain load current will pass through the cables, which will cause the cables to generate a certain amount of heat during use. There may be multiple cables in the existing cable tray at the same time, and since the ventilation in the factory is usually poor, the heat generated by the cables is easy to accumulate in the cable tray, especially at the corners of the cable tray. The cables are prone to entanglement and stacking, which may cause the cables to heat up severely and be damaged. In addition, some cables that do not generate much heat may be affected by other cables that generate much heat, causing the cables that do not generate much heat to fail to work normally. For this reason, we propose a steel structure cable tray structure. Utility Model Content
