Combined fireproof cable tray for power supply system cable and installation method of combined fireproof cable tray

Abstract

The invention discloses a combined fireproof cable tray for a power supply system cable. The combined fireproof cable tray includes a channel and a protective cover; the channel is composed of a left side wall beam and a right side wall beam which are in bilateral symmetry, and a bottom plate; the protective cover includes a protective cover plate and clamping buckles; two rows of round holes are uniformly formed in the protective cover plate; the left side wall beam has the same structure as the right side wall beam; the left side wall beam is composed of a side wall plate and a fixing groove; the upper end of the side wall plate extends outwards so as to form a slide groove; the protective cover slides on the left side wall beam and the right side wall beam through the clamping buckles; fixing frames symmetrically extend out from two ends of the side wall plate; fixing holes are formed in the fixing frames respectively; two rows of vent pipes are uniformly formed in the bottom plate; and the bottom plate is inserted into the fixing grooves of the left side wall beam and the right side wall beam, so that a U-shaped structure of the channel can be formed. The invention also provides an installation method of the combined fireproof cable tray. The installation method of the combined fireproof cable tray has the advantages of being simple and feasible, short installation time, low labor intensity and high work efficiency. The combined fireproof cable tray has the advantages of simple structure, convenience in transportation, simple assembly and disassembly and good fireproof performance, and can protect the cable.

Description

technical field [0001] The invention relates to a cable laying device in a power supply system, in particular to a combined fireproof bridge frame for cables in a power supply system and an installation method thereof. Background technique [0002] At present, frequency conversion power supply and shore power supply are often used in the power supply system. During operation, the laying of cables for power transmission has become a major problem. The laying is irregular, which will affect future disassembly and maintenance, and will also increase accidents in the power supply system. frequency; the cable tray product is a new type of cable laying device developed by industrially developed countries in the early 1960s; with the high development of electrification and automation, especially the change of power distribution mode, the direct burial of trenches and the laying of cables on brackets are no longer enough.

Problems solved by technology

[0002] At present, frequency conversion power supply and shore power supply are often used in the power supply system. During operation, the laying of cables for power transmission has become a major problem. The laying is irregular, which will affect future disassembly and maintenance, and will also increase accidents in the power supply system. frequency; the cable tray product is a new type of cable laying device developed by industrially developed countries in the early 1960s; with the high development of electrification and automation, especially the change of power distribution mode, the direct burial of trenches and the laying of cables on brackets are no longer enough. The use requirements are replaced by a cable bridge with low cost, fast construction, flexible wiring, easy loading and unloading, not limited by location, and beautiful at the same time, thus speeding up the construction progress, ensuring quality, and realizing product standardization, Serialization and generalization; bridges are widely used in petroleum, chemical, telecommunications and other industries. Most of the existing bridges are integrally fixed. During transportation, the transportation of integral bridges is very inconvenient; on the other hand, When the bridge frame is changed and expanded, its installation environment often changes. Since the bridge frame is fixed, it will bring trouble to the secondary installation of the bridge frame.

[0003] The existing bridges are prone to aging and corrosion due to long-term exposure during use, and the fire resistance and fire resistance are poor in the event of a fire, which affects the service life and increases the cost; in addition, due to the large size of the bridge during installation, the installation operation is inconvenient and takes a long time , and the amount of labor is also large, therefore, developing a bridge frame that can overcome the above defects has become a technical problem to be solved urgently by those skilled in the art
