[0021] The present invention is further described below in conjunction with specific embodiments and drawings. More details are elaborated in the following description to facilitate a full understanding of the present invention. However, the present invention can obviously be implemented in a variety of other ways different from the description. Those skilled in the art can make similar generalizations and deductions based on actual application situations without violating the connotation of the present invention. Therefore, the protection scope of the present invention should not be limited by the content of this specific embodiment.

[0022] It should be noted that these and other subsequent drawings are only examples and are not drawn in proportion, and should not be used as a limitation on the actual scope of protection required by the present utility model.

[0023] Reference Figure 4 It is understood that for adjacent fixed cable trays with a certain height difference, such as the first cable tray 100 is located at a first height and the second cable tray 200 is located at a second height, a switching cable tray 300 is required to solve the height difference.

[0024] Transfer cable tray 300 reference Figures 1 to 3 As shown, the switching cable tray 300 includes a plurality of bearing units 301 , and the bearing units 301 are used to bear a plurality of cables 400 , 400 ′ of the same specification or different specifications. The plurality of cables are laid on the switching cable tray 300 side by side.

[0025] Specifically, each load-bearing unit 301 includes two wing plates 33 facing each other and a binding frame 34 connecting the two wing plates 33. The binding frame 34 is provided with a bar hole 35 for connecting with the binding bar for bundling cables. The wing plates are provided with connection holes such as long waist-shaped holes for fixing the bridge frame.

[0026] The hinged portion 36 is disposed on the wing plate 33 and rotatably connects the adjacent bearing units 301. The adjacent bearing units adjust their relative angles with the aid of the hinged portion 36, thereby adjusting the overall height of the transfer cable tray 300.

[0027] like Figure 1 and Figure 3 As shown, the wing plate 33 is a C-shaped structure. Preferably, the length of the upper portion 331 of the C-shaped structure is smaller than the length of the lower portion 332, which can maximize the utilization rate of the plate and reduce the cutting of the plate.

[0028] The end of the wing plate 33 includes an arc-shaped folding piece 32, and the hinge part 36 is arranged on the arc-shaped folding piece 32. In some embodiments, the hinge part 36 includes a connecting bolt 31, which penetrates two adjacent bearing units to form the arc-shaped folding piece 32 and is fixed by a nut 37. The bolt hole is on the side and does not occupy the cable binding and laying area.

[0029] Further, the bearing unit 301 includes a middle bearing unit A and end bearing units B located at both ends, and the end bearing units B are used to be fixedly connected to the fixed cable tray. In some embodiments, the end bearing units B are fixedly connected to the first cable tray 100 and the second cable tray 200, and the end bearing units B are rotatably connected to the middle bearing unit A.

[0030] That is, the middle load-bearing unit A and the end load-bearing units B at both ends form a three-section bridge. In a specific embodiment, the two side wing plates of the first part of the middle load-bearing unit A are bent into a C-shaped form by steel sections, the upper side of the C-shaped form is a short side, the lower side is a long side, and the side is punched with a long waist-shaped hole for fixing the bridge. The two ends of the middle section of the bridge are semicircular folding parts, forming an arc-shaped folding part 32, and a 10mm hole is drilled in the center of the circle to connect the bolts. The binding strip for bundling the cables passes through the strip hole 35 on the bundling frame 34 between the two wing plates 33 to complete the fixation. One end of the second part of the end load-bearing unit B is a semicircular non-folding part, forming an arc-shaped folding part 32, and a 10mm hole is drilled in the center. The strip hole 35 is set on the bundling frame 34, which has the same function as the middle load-bearing unit A. The two end load-bearing units B and one middle load-bearing unit A are connected by connecting bolts through the circular holes to achieve angle adjustment, which can facilitate the laying of cables in response to complex on-site structures or manufacturing errors.

[0031] Figures 2A-2D The transfer cable tray is shown in the "bend", "upright", "straight through" and "up and down bend" states respectively to adapt to the height requirements of rising or falling, and to adapt to the height difference of different distances. It can be understood that by increasing or decreasing the number of the carrying units 301, the overall height of the transfer cable tray can be further adjusted.

[0032] During installation, the height of the bridge is changed according to actual needs at the construction site, and then the bolts are tightened to fix the shape. The two ends are connected to the fixed first bridge 100 and the second bridge 200. After fixing, there is no need to adjust the bracket angle.

[0033] The above-mentioned transfer cable tray has the following advantages:

[0034] (1) Using different numbers of bearing units in different forms, the transfer cable tray can form different overall heights. The straight bracket can be changed into various forms of cable trays such as bent, straight, and oblique, and the angle is adjustable to solve the problem of different height differences, reduce the on-site cutting and splicing of the tray and the customization of design and production, and reduce the types of customization;

[0035] (2) Multiple cables are bundled and fixed on the holes on the bundling frame, so that the cables can be neatly laid side by side in the load-bearing unit without wasting the bundling space defined by the load-bearing unit, thereby efficiently realizing the installation and laying of the cables.

[0036] Combined with the introduction of the above-mentioned transfer cable tray, a cable tray assembly can also be understood, which includes a first tray 100, a second tray 200 and the above-mentioned transfer cable tray. The first tray is fixedly set at a first height, the second tray is fixedly set at a second height, the two ends of the transfer cable tray 300 are respectively connected to the first tray 100 and the second tray 200, and a plurality of cables 400 are fixed side by side on the first tray, the second tray and the transfer cable tray.

[0037] The cable tray assembly can be flexibly installed in different ways according to different structures, and has the characteristics of simple operation, safety and durability. The assembly is suitable for various port container crane equipment such as quay cranes, tire cranes, and rail cranes.

[0038] It should be noted that the above content uses words such as "first" and "second" to limit components, which is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.
