[0041] Please refer to Figures 1 to 5 , this embodiment provides a high-level overlapping bridge. The high-level overlapping bridge is hoisted on the top of a building and is used for installing and supporting cables. The high-level overlapping bridge can be installed on the top of each floor of a building and can be applied to accommodate and protect various types of cables such as power supply cables and communication cables. The high-level overlapping bridge can achieve the vertical connection between the high-level cable box and the low-level cable box, improve the integration of the layout rationality of the bridge, and can be applicable to cables with different diameters and quantities, improving its flexibility in use.

[0042] As Figure 1 shown, in this embodiment, the high-level overlapping bridge includes: a high-level cable box 1, a low-level cable box 2, and an overlapping box connecting the high-level cable box 1 and the low-level cable box 2.

[0043] Among them, the high-level cable box 1 includes a first box body for installing and supporting cables; the low-level cable box, which is arranged below the high-level cable box, includes a second box body for installing and supporting cables, and its vertical projection is orthogonal to the first box body; the overlapping box 1c, the overlapping box 1c is vertically arranged at the projection intersection of the high-level cable box 1 and the low-level cable box 2. The overlapping box 1c has a space for cables to pass through inside. One end of the overlapping box 1c is vertically connected to the high-level cable box 1, and the other end of the overlapping box 1c is vertically connected to the low-level cable box 2;

[0044] The first box body can be one or more. For example, Figure 1 as shown, the high-level wire box 1 includes the first box body one 1b, the first box body two 2b, and the first box body three 3b. The second box body can be one or more. For example, Figure 1 as shown, the low-level wire box 2 includes the second box body one 1a, the second box body two 2a, and the second box body three 3a.

[0045] There can also be one or more overlapping boxes. For example, Figure 2 as shown, the first box body one 1b and the second box body one 1a are connected through the overlapping box 1c, so that the cable in the first box body one 1b can enter the second box body one 1a through the overlapping box 1c. Similarly, the cable in the first box body two 2b can also enter the second box body two 2a through the same overlapping box.

[0046] The first box body and the second box body are made of any one of aluminum, aluminum alloy, zinc alloy, and stainless steel. The overlapping box is a rectangular box body, and the two ends of the overlapping box are connected to the first box body and the second box body by any one of welding, bolt connection, and rivet connection.

[0047] In this embodiment, the high-level wire box 1 and the low-level wire box 2 are orthogonally arranged, and the first box body in the high-level wire box 1 is connected to the corresponding second box body in the low-level wire box 2 through the overlapping box, so that the cable in the first box body one can directly enter the corresponding second box body in the low-level wire box 2 through the overlapping box. It can not only realize horizontal wiring (that is, the high-level wire box 1 and the low-level wire box 2 can realize horizontal wiring on the same horizontal plane through a conventional three-way structure or four-way structure), but also realize vertical wiring, reduce the wire box elbows, improve the integration degree and space utilization rate of the cable tray, and make the layout of the cable tray more reasonable and regular.

[0048] For example, Figure 2 and Figure 3 as shown, in this embodiment, the first box body and the second box body both include a top cover plate 11, a bottom plate 12, and two side plates 13; the top cover plate 11 and the bottom plate 12 are arranged opposite to each other in the vertical direction, and the two side plates 13 are symmetrically arranged in the horizontal direction on both sides of the top cover plate 11 and the bottom plate 12, and enclose a sealed space for accommodating the cable with the top cover plate 11 and the bottom plate 12.

[0049] For example, Figure 3 as shown, in this embodiment, the side plate 13 is a C-shaped plate, and both ends of the side plate 13 are provided with connecting parts 131 protruding towards the middle; the connecting parts 131 are respectively connected to the top of the corresponding side top cover plate and the bottom of the bottom plate. The top cover plate 11 and the bottom plate 12 are U-shaped plates arranged symmetrically.

[0050] The top cover plates of the first box body and the second box body are respectively provided with suspension rods 15, and the tops of the suspension rods 15 are fixed to the top of the building.

[0051] Therefore, the connection strength between the bottom plate 12 and the top cover plate 11 can be improved through the connecting portion 131, and the weight of the cables borne by the bottom plate can be transmitted to the top cover plate 11. Thus, as Figure 3 shown, in this embodiment, the suspension rods 15 can be arranged on the top cover plate 11, and the entire box body can be suspended from the top of the building through the suspension rods 15. In the related art, the box body for wiring in the cable tray is only composed of a top cover plate and a U-shaped bottom plate. Therefore, the space inside the box body for wiring in the related art is fixed, and the top cover plate cannot bear the weight of the cables. Therefore, in the related art, the cable tray can only be installed in a bottom-suspension manner, that is, a U-shaped hanging arm is used to suspend the box body from the bottom of the box body and install it on the top of the building. In this embodiment, the first box body and the second box body both include a top cover plate 11, a bottom plate 12 and two side plates 13, and there are connecting portions 131 at both ends of the side plates 13. Therefore, the top-suspension installation can be realized through the suspension rods 15.

[0052] As Figure 4 and Figure 5 shown, the top cover plate 11 and the bottom plate 12 of the first box body or the second box body are both formed by splicing two or more plate bodies in the width direction; the two side plates 13 are arranged on both sides of the top cover plate 11 and the bottom plate 12 formed by the splicing.

[0053] In this embodiment, since the first box body and the second box body are applied to the structure of enclosing and splicing the top cover plate 11, the bottom plate 12 and the two side plates 13, the internal sizes of the first box body and the second box body can be adjusted according to the diameter and quantity of the cables to be accommodated. That is, when the diameter of the cables is larger or the quantity is more, two or more top cover plates in Figure 3 can be spliced into Figure 4 and Figure 5 shown, a spliced top cover plate with a larger width, so that the internal space of the first box body and the second box body is larger, and cables with a larger diameter or a larger quantity can be accommodated.

[0054] As Figure 4 and Figure 5 shown, in the above embodiment, in order to improve the overall strength of the top cover plate and the bottom plate formed by the splicing, connecting pieces 14 are arranged at the splicing joints of the top cover plate and the bottom plate. Both ends of the connecting piece 14 are fixedly connected to the corresponding plate bodies through fasteners.

[0055] Finally, it should be noted that although the above embodiments have been described in the text and drawings of the specification of this application, the patent protection scope of this application cannot be limited thereby. Any technical solutions generated by equivalent structure or equivalent process substitution or modification based on the essential concept of this application and using the content recorded in the text and drawings of the specification of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, etc., are all included in the patent protection scope of this application.
