Description

Technical Field

[0001] The utility model relates to the technical field of cable trays, and particularly relates to a composite cable tray for mechanical and electrical installation. Background Art

[0002] Cable trays are divided into trough type, tray type, ladder type, grid type and other structures, and are composed of brackets, cantilever arms and installation accessories, etc. The cable trays in buildings can be erected independently or laid on various building and pipe gallery brackets, and should reflect the characteristics of simple structure, beautiful shape, flexible configuration and convenient maintenance, etc. The composite cable tray, that is, the combined cable tray, is a new type of cable tray and is the second-generation product in the cable tray series. It is applicable to the laying of various projects, various units and various cables, and has the characteristics of simple structure, flexible configuration, convenient installation and novel form.

[0003] The existing elbow structure of the composite cable tray is as Figure 3 shown. Although it can turn the cables, it cannot stratify multiple cables. When two layers of cables need to be arranged, another elbow structure needs to be additionally installed on it for climbing and bending, which increases the installation difficulty, is time-consuming and laborious, and is not beautiful. Content of the Utility Model

[0004] Aiming at the above problems in the prior art, the utility model provides a composite cable tray for mechanical and electrical installation, which solves the problem of cumbersome installation when the elbow structure of the existing composite cable tray stratifies cables.

[0005] In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

[0006] Provide a composite cable tray for mechanical and electrical installation, including a bent bridge floor, a first outer wall plate and a second outer wall plate are respectively arranged on both side edges of the bridge floor, a middle partition is arranged in the middle of the bridge floor, and the distances between the two side surfaces of the middle partition and the wall surfaces of the first outer wall plate and the second outer wall plate are equal everywhere. A plurality of galvanized steel pipes are arranged between the first outer wall plate and the second outer wall plate and the middle partition.

[0007] In this scheme, the arrangement of a plurality of galvanized steel pipes can directly lay cables in layers without additionally arranging an elbow structure, and there is no situation of climbing and bending with each other. Moreover, by arranging a middle partition in the middle of the bridge floor, different layers of cables can be effectively physically isolated, reducing the mutual interference between cables, and at the same time, it is also convenient for maintenance and management.

[0008] Furthermore, the bent part of the bridge floor is processed with rounded corners to facilitate the bending of cables.

[0009] Further, the first outer wall plate, the second outer wall plate, and the middle partition all have the same height. Setting the same height helps to improve the consistency and aesthetics of the entire cable tray structure, and also facilitates standardized production and installation.

[0010] Further, inner partition plates are provided at both ends of the middle partition. Both inner partition plates are U-shaped plate structures, and the middle parts of the bottom plates of the two inner partition plates are fixedly connected to both ends of the middle partition respectively. The setting of the inner partition plates further expands the distance between the cables on both sides of the middle partition, improving the discrimination degree.

[0011] Further, the first outer wall plate is located on the outer side edge of the cable tray bottom plate, and a rectangular opening for the cable to pass through is provided on the wall surface of the first outer wall near the bending part. Setting the rectangular opening on the first outer wall plate facilitates the access or passing of the cable, simplifies the cable wiring process, and improves the installation efficiency.

[0012] Further, a U-shaped plate for receiving the cable is fixed at the rectangular opening of the first outer wall plate. Installing the U-shaped plate at the rectangular opening position can better support and guide the cable.

[0013] Further, multiple galvanized steel pipes located on both sides of the rectangular opening on the first outer wall are arranged perpendicular to each other. Distributing the multiple galvanized steel pipes in this way enhances the overall structural stability of the cable tray.

[0014] Further, the distance between two adjacent galvanized steel pipes is 40 mm to 60 mm.

[0015] Further, the diameter of each galvanized steel pipe is 20 mm to 30 mm, and the wall thickness is 2 mm to 3 mm. Setting the diameter and wall thickness of the galvanized steel pipe in this way ensures sufficient strength while reducing the weight of the cable tray.

[0016] The utility model discloses a composite cable tray for mechanical and electrical installation, and its beneficial effects are as follows:

[0017] With the setting of multiple galvanized steel pipes in the utility model, the cables can be directly laid in layers without the need to additionally arrange elbow structures, and there is no situation of climbing and bending around each other. At the same time, the installation is convenient, time-saving and labor-saving. By setting a middle partition in the middle of the cable tray bottom plate, different layers of cables can be effectively physically isolated, reducing the mutual interference between the cables, and also facilitating maintenance and management.

Preferably, in this embodiment, the diameter of each galvanized steel pipe 5 is 25 mm, and the wall thickness is 2.8 mm. By setting the diameter and wall thickness of the galvanized steel pipe 5 in this way, the weight of the bridge is reduced while ensuring sufficient strength. And multiple galvanized steel pipes 5 located on both sides of the rectangular opening on the first outer wall are arranged perpendicular to each other. By distributing multiple galvanized steel pipes 5 in this way, the overall structural stability of the bridge is enhanced.
