Description

Technical Field

[0001] This utility model belongs to the field of cable tray windproof technology, and specifically relates to a cable tray windproof device. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] As the refining and chemical industry develops towards an integrated refining and chemical pattern, various refining and chemical facilities are being built in major chemical bases. Due to the strong winds in coastal areas, especially during the typhoon season, strong winds can easily overturn and damage cable trays, causing power supply and distribution system and signal transmission failures.

[0004] Existing cable tray fixing methods involve securing the trays to supports with clamps and then binding the cable tray covers with cable ties. While suitable for general environments, this approach is ineffective in strong winds or areas with frequent strong winds. Sustained strong winds can cause the trays to sway and eventually overturn. Another method involves adding windproof clips to the existing cable trays to prevent the covers from being blown off by strong winds. However, since the cable trays are mounted on supports, simply protecting the covers is insufficient to completely prevent overturning and damage. Further modifications to the cable tray structure, such as increasing sealing or strength, can reduce the impact of strong winds. However, this requires large-scale replacement of existing cable trays, increasing the cost and reducing the efficiency of retrofitting. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a windproof device for cable trays, which can improve the wind resistance of cable trays and reduce the cost of cable tray renovation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0012] Furthermore, the upper end of the second connecting rod passes through the clamping bracket and is connected to the second fastener, and the lower end of the second connecting rod passes through the bridge bracket and is connected to the first fastener.

[0013] Furthermore, the lower surface of the clamping bracket is in close contact with the upper surface of the cable tray, and the lower surface of the cable tray is in close contact with the upper surface of the cable tray bracket.

[0014] Furthermore, the width of the clamping bracket is greater than the width of the cable tray.

[0022] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0023] The present invention will be described in detail below with reference to the accompanying drawings. This embodiment discloses a windproof device for cable trays, such as... Figure 1 As shown, the cable tray includes a cable tray support 4, a cable tray 5 is provided at the upper end of the cable tray support 4, and a clamping bracket 1 is provided at the upper end of the cable tray 5; a first connecting rod 2 is provided at one end of the cable tray 5, a second connecting rod 6 is provided at the other end of the cable tray 5, a first fastener 3 is provided at the lower end of the first connecting rod 2 and the second connecting rod 6, and a second fastener 7 is provided at the lower upper end of the first connecting rod 2 and the second connecting rod 6.

[0024] The first fastener 3 is located at the lower end of the cable tray support 4, and the second fastener 7 is located at the upper end of the clamping bracket 1. The first fastener 3, together with the first connecting rod 2 and the second connecting rod 6, presses the clamping bracket 1 firmly against the upper end of the cable tray 5, thereby preventing the cover of the cable tray 5 from being blown off by strong winds. The clamping bracket 1 is made of L40x4 angle steel, which has sufficient strength to ensure the stability of the overall structure.

[0025] Bolt holes are provided at both ends of the clamping bracket 1 and the cable tray bracket 4. The bolt holes of the clamping bracket 1 and the cable tray bracket 4 are aligned vertically. The bolt holes of both the clamping bracket 1 and the cable tray bracket 4 are Φ13 bolt holes. During installation, align the bolt holes of the clamping bracket 1 and the cable tray bracket 4, and then screw in the connecting rod to connect the clamping bracket 1 and the cable tray 5 into one unit.

[0026] The upper end of the first connecting rod 2 passes through the bolt hole at one end of the clamping bracket 1, and the lower end of the first connecting rod 2 passes through the bolt hole at one end of the cable tray bracket 4. The upper end of the first connecting rod 2 passes through the clamping bracket 1 and connects to the second fastener 7, and the lower end of the first connecting rod 2 passes through the cable tray bracket 4 and connects to the first fastener 3. The upper end of the second connecting rod 6 passes through the bolt hole at the other end of the clamping bracket 1, and the lower end of the second connecting rod 6 passes through the bolt hole at the other end of the cable tray bracket 4. The upper end of the second connecting rod 6 passes through the clamping bracket 1 and connects to the second fastener 7, and the lower end of the second connecting rod 6 passes through the cable tray bracket 4 and connects to the first fastener 3.

[0027] The first connecting rod 2 and the second connecting rod 6 are Φ12 galvanized threaded rods. The galvanizing process provides rust resistance and enhances durability. The first fastener 3 and the second fastener 7 are M12 galvanized nuts. The galvanizing process also provides rust resistance, allowing them to be used in conjunction with the threaded rods for extended periods.

[0028] One end of the connecting rod passes through the clamping bracket 1, and the other end passes through the cable tray bracket 4. Fasteners are screwed onto the portion passing through the clamping bracket 1 and the cable tray bracket 4. The connecting rod serves two purposes: firstly, it clamps and fixes the cable tray 5 between the clamping parts and the cable tray bracket 4; secondly, because of the bolted connection, it allows for easy disassembly when the cable tray needs to be disassembled for cable laying or other maintenance work. The diameter of the fastener is larger than the diameter of the threaded hole, ensuring that the surface of the fastener is in close contact with the surfaces of the clamping bracket 1 and the cable tray bracket 4.

[0029] The lower surface of clamping bracket 1 is in close contact with the upper surface of cable tray 5, and the lower surface of cable tray 5 is in close contact with the upper surface of cable tray bracket 4. The width of clamping bracket 1 is greater than the width of cable tray 5. The width of cable tray bracket 4 is greater than the width of both cable tray 5 and clamping bracket 1. Cable tray bracket 4 provides support, facilitating cable laying of cable tray 5, and, together with connecting rods, fasteners, and clamping supports, secures cable tray 5. The larger width of cable tray bracket 4 allows for pre-installed installation positions for fasteners and connecting rods. The larger width of clamping bracket 1 allows for pre-installed installation positions for connecting rods and fasteners, while simultaneously pressing down on the entire cable tray 5.

[0030] The clamping bracket 1, the first connecting rod 2, the second connecting rod 6, the first fastener 3, the second fastener 7, and the cable tray bracket 4 form a U-shaped structure, with the cable tray 5 housed within this U-shaped structure. Within the U-shaped structure, the cable tray 5 is firmly secured to the clamping components and the cable tray bracket 4 via the connecting rods. Even in strong winds, because the cable tray bracket 4 is firmly fixed, the cable tray within the U-shaped structure is also securely fixed and will not be damaged by strong winds.

[0031] Working principle: Before the cable tray 5 is installed, clamping brackets 1, connecting rods, and cable tray supports 4 are uniformly fabricated according to the width of the cable tray, and holes are uniformly drilled. After the cable tray 5 is installed, it is tightened with fasteners to complete the strong wind protection measure. In strong wind weather, because the connecting rods tighten the clamping brackets 1 and cable tray supports 4 into a "U"-shaped structure, the cable tray 5 will be reliably fixed in the "U"-shaped structure and will not be overturned by strong winds.

[0032] When cable trays need to be modified, simply make threaded holes in the existing cable tray bracket 4, align the threaded holes of the clamping bracket with the newly made threaded holes, and then screw in the connecting rods and fasteners in sequence to complete the modification. The modification is highly efficient.

[0033] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
