Problems solved by technology

[0003] The metal bridge is heavy and easy to rust, the installation process is complex, cumbersome, and the installation cost is high, and the metal bridge is subjected to current induction all the year round, coupled with the formation of stray currents in the power transmission process, electrolytic corrosion is formed in the metal bridge, which accelerates The decay of the metal bridge, at the same time, the rotten bridge interacts and corrodes the cable skin, which makes the cable skin age prematurely, so that the quality of the bridge cannot be guaranteed, which greatly reduces the service life of the cable and the bridge
[0004] FRP bridge frame is made of resin, magnesium oxide, magnesium chloride and glass fiber cloth, but its oxidation speed is fast. Within 2-3 years, you can see the powdery substance falling from FRP itself. The chemical properties are extremely poor. These powders When the like substance encounters moisture in the air, it will generate an alkaline solution, which will corrode the skin of the cable, shorten the service life of the cable, and hide great troubles for future cable laying.

Embodiment 1

[0043] A new type of polymer alloy plastic hollow cable tray, including detachable bridge body 1 and bridge cover 2, both of which are made of high-tech polymer materials PVC and ABS polyphenylene oxide and other organic materials. It has excellent comprehensive performance, high impact strength, good dimensional stability, excellent corrosion resistance and high gloss.

[0044] In this example, if figure 2 , 6 As shown in and 11, the bridge body 1 includes a bottom plate 11 and vertical side portions 12 extending vertically upward on both sides of the bottom plate 11 to form a groove-shaped bridge, and the upper end of the vertical side portion 12 extends vertically inward to form a mounting portion. And the upper end of the installation part is integrally formed with a lower buckle part 13, a plurality of equidistantly arranged second cavities 15 are arranged in the bottom plate 11 and the vertical side part 12, and the cross-section of the second cavities 15 is Rectangul...

Embodiment 2

[0051] The difference between this embodiment and embodiment 1 is that, as Figure 4-6 As shown, further, the inner cavity of the bridge body 1 is provided with a plurality of partition plates 3 arranged in parallel vertically, and a plurality of cooling holes 31 are distributed in a matrix on the side wall of the partition plate 3, and a plurality of optional The assembled partition plate 3 can effectively ensure the arrangement of the cables, and is convenient for installation and maintenance. Combined with the design of multiple cooling holes 31, the heat dissipation effect is better, and the stable transmission and operation of the cables to the power is guaranteed.

[0052] In this example, if figure 1 , 2 As shown in and 11, the upper end surface of the bottom plate 11 is provided with a plurality of upper buckle grooves 19 matching the lower end surface of the partition plate 3, and the opposite side walls of the upper buckle grooves 19 are inwardly convex arcs. The s...

Embodiment 3

[0055] The difference between this embodiment and embodiment 2 is that, as Figure 5 , 8 Shown in and 9, also include the protective edge plate 4 that is symmetrically arranged on both sides of the bridge body 1, the protective edge plate 4 includes an L-shaped side protective edge 41, and the side protective edge 41 is close to the side of the bridge body 1 side A horizontal section and a vertical section are provided with a plurality of strip buckles 42 extending along the installation direction of the bridge body. The strip buckles 42 have a rectangular structure, and both sides of the strip buckles 42 are outwardly facing. The raised arc structure, the installation of the protective side plate 4 can effectively ensure its fixing and protective effect on the side of the bridge body 1, and cooperate with the L-shaped structure of the side protective side 41, which can also share the weight of the bottom plate 11. function, the protective effect is better.

Abstract

The invention relates to the technical field of cable bridges, provides a novel high-molecular alloy plastic hollow cable bridge, and aims to solve the problems that most cable bridges are made of metal and glass fiber reinforced plastic products in the prior art, there are various disadvantages, and a cable bridge which is convenient to install and has excellent comprehensive performance is urgently needed in the market. The cable bridge comprises a bridge body and a bridge cover which are detachable, wherein the bridge body comprises a bottom plate and vertical side edge parts vertically extending upwards from the two sides of the bottom plate, the upper ends of the vertical side edge parts vertically extend inwards to form installation parts, the upper ends of the installation parts areintegrally provided with lower buckling parts, and the bottom plate and the vertical side edge parts are both internally provided with a plurality of second cavities which are arranged at equal intervals. The cable bridge is particularly suitable for meeting the requirement of high-quality cable bridges in the current market, and has high social use value and application prospect.

Description

technical field [0001] The invention relates to the technical field of cable bridges, in particular to a novel polymer alloy plastic hollow cable bridge. Background technique [0002] With the development of my country's economic construction, cable trays have been more and more widely used, which makes the equipment of wires, cables, and optical cables standardized, serialized, and generalized. In terms of using bridge installations, most of the existing technologies Made of metal and fiberglass, there are various disadvantages. [0003] The metal bridge is heavy and easy to rust, the installation process is complex, cumbersome, and the installation cost is high, and the metal bridge is subjected to current induction all the year round, coupled with the formation of stray currents in the power transmission process, electrolytic corrosion is formed in the metal bridge, which accelerates The decay of the metal bridge, and the rotten bridge interacts to corrode the cable skin,...
