Description

Technical Field

[0001] The utility model relates to the technical field of cable trays, in particular to a trough-type fireproof cable tray. Background Art

[0002] A cable tray is an important device for cable laying and management, which is widely used in places such as buildings, industrial facilities, data centers, etc. It is mainly made of metal or non-metal materials and has a bridge structure for installing and supporting cables. The cable tray consists of crossbeams, longitudinal beams, connectors, etc., and can be installed on walls, ceilings, floors, etc. for cable laying and management. There are various structural types of cable trays, such as trough type, tray type, ladder type, and grid type, etc. Each structure has its own characteristics and application scenarios. For example, the trough-type cable tray is a fully enclosed cable tray, which is suitable for laying control cables of high-sensitivity systems such as computer cables and communication cables; the tray-type cable tray is suitable for laying power, communication, signal and other lines; the ladder-type cable tray has good ventilation performance and is suitable for laying larger cables. When selecting a cable tray, factors such as the type, quantity, diameter of the cable, and installation environment need to be considered. At the same time, aspects such as the material, anti-corrosion performance, and load-bearing capacity of the cable tray are also important considerations. For special environments, such as the seaside or corrosion areas, it is also necessary to select a tray material with anti-corrosion and moisture-resistant characteristics.

[0003] When supporting cables, a trough-type cable tray is needed for support. The patent publication number is CN113972607B. The present invention provides a trough-type cable tray, which relates to the technical field of cable trays. The trough-type cable tray includes two trays. An installation groove is formed on the upper surface of the tray. It also includes two arc-shaped plates. One of the arc-shaped plates has a first outer arc surface and a first inner arc surface. The other arc-shaped plate has a second outer arc surface that can be in full contact with the first inner arc surface. The arc-shaped plate also has a second inner arc surface. One end of the two trays is detachably connected to the two arc-shaped plates respectively; the arc-shaped plate rotates ninety degrees relative to the arc-shaped plate to achieve the function of a bend. When the second outer arc surface of the arc-shaped plate fits on the first inner arc surface of the arc-shaped plate, it plays the role of laying the trays side by side. When the arc-shaped plate rotates one hundred and eighty degrees relative to the arc-shaped plate, it plays the role of lengthening the tray, reducing the number of tray assemblies. Therefore, the present invention takes less time and the laying efficiency of the tray is significantly improved.

[0004] The above-mentioned prior art solutions have the following defects: When the existing trough-type cable tray encounters a fire, the temperature inside the trough-type tray will become higher and higher under the burning of the flame, resulting in the cable being unable to be used due to excessive temperature.
