[0023] Please refer to Figures 1-4, in the present utility model, the structure of the molded double-layer heat-insulating and fire-proof cable tray includes a tray main body 1. A first heat-insulating and fire-proof board 2 is fixedly connected to the inner bottom wall of the tray main body 1. Two second heat-insulating and fire-proof boards 3 are fixedly connected to the inner wall of the tray main body 1. A partition board 4 is fixedly connected to the mutually approaching surfaces of the two second heat-insulating and fire-proof boards 3. Two clamping seats 5 are fixedly connected to the outer surface of the tray main body 1. A tray cover plate 6 is placed on the upper surface of the tray main body 1. Two clamping plates 7 are fixedly connected to the bottom surface of the tray cover plate 6. The inner walls of the two clamping seats 5 are respectively clamped with the outer surfaces of the clamping plates 7. A third heat-insulating and fire-proof board 8 is fixedly connected to the bottom surface of the tray cover plate 6. The tray main body 1 is the overall structure of the cable tray. The first heat-insulating and fire-proof board 2 insulates and prevents fire on the inner bottom surface of the tray main body 1. The second heat-insulating and fire-proof boards 3 insulate and prevent fire on the side walls of the tray main body 1, thereby insulating and preventing fire inside the cable. The partition board 4 divides the interior of the tray main body 1 into two layers, enabling the tray main body to achieve a double-layer cable tray structure. The clamping plates 7 on the tray cover plate 6 are clamped in the clamping seats 5, thereby fixing the tray cover plate 6 on the tray main body 1 to cover the upper part of the tray main body 1. Together with the third heat-insulating and fire-proof board 8, it provides more comprehensive heat insulation and fire prevention for the internal cables.

[0024] A protective pad 9 is fixedly connected to the upper surface of the partition board 4. A plurality of small holes 10 are commonly formed on the outer surface of the partition board 4 and the outer surface of the protective pad 9. A plurality of ventilation holes 11 are commonly formed on the outer surface of the tray cover plate 6 and the outer surface of the third heat-insulating and fire-proof board 8. Two groups of mounting seats 12 are fixedly connected to both the front surface and the back surface of the tray main body 1. The inner walls of each group of mounting seats 12 are respectively clamped with a mounting plate 13. The outer surfaces of the four mounting plates 13 are commonly in contact with the outer surface of the tray main body 1. The protective pad 9 protects the cables placed on the partition board 4 to prevent the cables from being worn due to friction with the partition board 4. The small holes 10 and the ventilation holes 11 respectively dissipate heat from the air exchange between the tray cover plate 6 and the outside and the cables on the partition board 4, improving the practicability of this structure. The mounting plates 13 are clamped in the mounting seats 12 to connect and install the tray main bodies 1, facilitating the installation of the tray main body 1.

[0025] The outer surface of the tray main body 1 is sprayed with fire-proof paint. The first heat-insulating and fire-proof board 2 is made of heat-insulating and fire-proof materials. Each second heat-insulating and fire-proof board 3 is made of heat-insulating and fire-proof materials. The third heat-insulating and fire-proof board 8 is made of heat-insulating and fire-proof materials. The fire-proof paint has a fire-proof effect, enabling the exterior of the tray main body 1 to have a fire-proof function. The heat-insulating and fire-proof material is a silicon-aluminum plate, also called a ceramic fiber board, which has high temperature resistance, A1-level fire protection, can be arbitrarily shrunk, has good compressive performance, is light in weight, is convenient for transportation and construction, and has a strong adhesion force, greatly improving the construction efficiency.

[0026] The working principle of the present utility model is:

[0027] First, place the cable in the bridge main body 1 and on the partition 4, use the clamping plate 7 to clamp in the clamping seat 5, install and fix the bridge cover plate 6 above the bridge main body 1 to cover the upper part of the bridge main body 1, and then use the first heat-insulating and fire-proof board 2, the second heat-insulating and fire-proof board 3 and the third heat-insulating and fire-proof board 8 to conduct heat insulation and fire prevention on the cable placed inside. When the internal air pressure is uneven with the outside world, use the small hole 10 and the air-permeable hole 11 to exchange the air inside and outside. When installing each bridge main body 1, use the clamping block on the mounting plate 13 to clamp in the groove in the mounting seat 12 to connect and install each bridge main body 1.

[0028] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
