Description

Technical Field

[0001] The utility model relates to the technical field of cable bridges, in particular to a fireproof bridge with a drainage function. Background Art

[0002] Cable bridges are divided into trough cable bridges, tray cable bridges, ladder cable bridges, grid bridges and other structures, which are composed of brackets, brackets and installation accessories. They can be erected independently or laid on various buildings (structures) and pipe gallery brackets, reflecting the characteristics of simple structure, beautiful shape, flexible configuration and convenient maintenance. All parts must be galvanized. If the bridge is installed outside the building in the open air, if it is near the seaside or in a corrosion zone, the material must have the physical properties of corrosion resistance, moisture resistance, good adhesion and high impact resistance. Cable bridges are usually made of metal, which makes the cable bridge itself have good fire resistance.

[0003] The functions of cable trays include the following aspects: 1. Cable trays can be suspended or placed on the ground to act as a skeleton to support cables; 2. Cable trays can isolate cables from the outside world to a certain extent, thereby protecting cables and effectively preventing cables with large spans from sagging due to their own weight; 3. It is convenient for centralized management of multiple cables and can lay out cables scientifically, making the cable layout beautiful and helping to save space.

[0004] In the related art, some cable bridges used outdoors are also provided with covers on top to better protect the cables inside, but the covers are usually simply connected. When it rains, rainwater can easily enter the bridge through the gap between two adjacent covers, causing the cables inside the bridge to be soaked in water, which will affect the insulation performance of the cable sheath.

[0008] Furthermore, the cross-sectional shapes of the two side wall outer walls and the cover plate inner wall are both arc-shaped, and the curvature radii of the arc-shaped outer walls of the two side walls and the arc-shaped inner wall of the cover plate are consistent, the two side walls are consistent in size, and the arc length of the arc-shaped inner wall of the cover plate is shorter than the arc length of the outer wall of the side wall.

[0009] Furthermore, a plurality of support blocks are arranged at intervals on the outer wall of any one of the side walls along the length direction of the bridge frame body, and one side of the cover plate is mounted on the support block of the corresponding side wall, and the other side extends to the other side wall.

[0010] Furthermore, each cover plate is also provided with a toggle block.

[0011] Furthermore, the bridge frame body includes a plurality of first-to-first-joint bridge frame short sections, each of which has a docking groove on the inner side of one end and a docking column on the other end. When two adjacent bridge frame short sections are docked, the docking column of one bridge frame short section extends into the docking groove of the other bridge frame short section for docking.

[0012] Furthermore, a plurality of drainage holes are provided at intervals on the bottom plate of the bridge frame body.

[0013] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0014] In the utility model, a barb is provided at one end of each cover plate, and an extension cover is provided at the other end of the cover plate, and a butt hook is provided on the extension cover to be hooked with the barb on the adjacent cover plate. Then, when two adjacent cover plates are butt-jointed, the extension cover can cover the gap between the two cover plates.

[0025] In this solution, a barb 5 is provided at one end of each cover plate 4, and an extension cover 6 is provided at the other end of the cover plate 4, and a docking hook 7 is provided on the extension cover 6 to be hooked with the barb 5 on the adjacent cover plate 4. Then, when two adjacent cover plates 4 are docked, the extension cover 6 can cover the gap between the two cover plates 4. At the same time, the docking hook 7 on the extension cover 6 extends to below the barb 5 of the other cover plate 4, which can further prevent rainwater from entering the interior of the cable tray body 1 through the gap between the two cover plates 4. Most of the rainwater can be discharged to the ground on both sides through the surface of the cover plate 4 above the cable tray body 1.

[0026] Example 2

[0027] Based on Example 1, in this example, reference Figure 1 The cross-sectional shapes of the outer walls of the two side walls 3 and the inner wall of the cover plate 4 are both arc-shaped, and the curvature radii of the arc-shaped outer walls of the two side walls 3 and the arc-shaped inner walls of the cover plate 4 are consistent. The two side walls 3 are consistent in size, and the arc length of the arc-shaped inner wall of the cover plate 4 is shorter than the arc length of the outer wall of the side wall 3.

[0028] Since the ends of multiple cover plates 4 are connected by hooks, when it is necessary to inspect and repair a local position of the bridge body 1, the cover plate 4 at the corresponding position can be rotated to make the corresponding cover plate 4 slide toward one side of the bridge body 1 until the corresponding cover plate 4 slides out from between the two adjacent cover plates 4. The corresponding cover plate 4 can then be taken out, making it convenient to inspect the cover plate 4, the local position of the bridge body 1 and the cables inside the bridge body 1.

[0029] Example 3

By providing the support blocks 8, one side of the plurality of cover plates 4 can be placed on the corresponding support blocks 8, so that the plurality of cover plates 4 can be arranged and docked along a straight line, the aesthetics of the layout of the cover plates 4 can be improved, and the plurality of cover plates 4 can be placed on the bridge body 1 more stably, reducing the cover plates 4 from sliding off on the bridge body 1.

[0031] Example 4

[0032] Based on Example 2, in this example, refer to Figure 1 , each cover plate 4 is also provided with a toggle block 9. When inspecting a local position of the bridge frame body 1, the maintenance personnel can move the toggle block 9 by hand, and then move the corresponding cover plate 4 out from between the cover plates 4 at both ends.

[0033] Example 5

[0034] Based on Example 1, in this example, reference Figure 2 , Figure 3 The bridge body 1 includes a plurality of bridge short sections 10 for first docking. A docking groove 11 is provided on the inner side of one end of each bridge short section 10, and a docking column 12 is provided on the other end. When two adjacent bridge short sections 10 are docked, the docking column 12 of one bridge short section 10 extends into the docking groove 11 of the other bridge short section 10 for docking. The two adjacent bridge short sections 10 are docked through the docking column 12 and the docking groove 11, which can prevent rainwater from entering the interior of the bridge body 1 through the gap between the two adjacent bridge short sections 10 to a certain extent.

[0035] Example 6

[0036] Based on Example 5, in this example, refer to Figure 2 A plurality of drainage holes 13 are provided on the bottom plate 2 of the bridge body 1. When encountering long-term rainy weather, some rainwater will inevitably seep into the inside of the bridge body 1. After the rainwater enters the inside of the bridge body 1, it can be discharged in time through the drainage holes 13 of the bottom plate 2 of the bridge body 1, which can reduce the depth, area and time of the cable soaking in water.
