Description

Technical Field

[0001] This utility model belongs to the field of workshop cable installation and layout technology, specifically relating to a new type of cable tray. Background Technology

[0002] As a core support structure for power and signal transmission systems, cable trays not only regulate cable layout but also ensure equipment operational stability through efficient heat dissipation. In industrial settings such as textile finishing equipment, where equipment is densely packed and ambient temperatures often exceed 60°C, traditional open-type cable trays, due to their limited heat dissipation structure, are prone to creating localized overheating areas in the cables. This leads to accelerated insulation aging, abnormally high contact resistance, and even the risk of short circuits. The shortcomings of existing cable trays, relying solely on natural convection for heat dissipation, are particularly pronounced in high-temperature equipment clusters such as stenter machines, impacting the continuous and safe operation of the equipment. Utility Model Content

[0003] To address the problem of uneven heat dissipation in existing cable trays under high-temperature and high-load conditions, leading to potential localized overheating, a novel cable tray design is proposed. This utility model provides the following technical solution: A novel cable tray includes a first support pipe and a second support pipe arranged in parallel for supporting and connecting an external air source. A plurality of connecting pipes for receiving cables upward are arranged at intervals between the first support pipe and the second support pipe. The upper end face of the connecting pipe is lower than the upper end face of the first support pipe and the second support pipe. The connecting pipe is interconnected with the first support pipe and the second support pipe. A plurality of air outlets for air-cooling cables are provided on the upper side of the connecting pipe.

[0004] Preferably, a first fixing plate is fixedly connected to the end of the first support tube, and the side of the first fixing plate is provided with screw holes for fixing with bolts.

[0005] Preferably, a second fixing plate is fixedly connected to the end of the second support tube, and the side of the second fixing plate is provided with screw holes for fixing with bolts.

[0006] Preferably, both the first support tube and the second support tube are square tubes.

[0007] Preferably, the connecting pipe is a square tube.

[0008] Preferably, the lower end face of the connecting pipe is flush with the lower end faces of the first support pipe and the second pipe.

[0009] Preferably, a rotating shaft is fixedly connected to the first support tube and / or the second support tube, and a stop bar for limiting the cable is rotatably connected to the rotating shaft.

[0010] Preferably, a first magnetic block is installed on the first support tube and / or the second support tube, and a second magnetic block for attracting the first magnetic block is installed on the lower side of the stop bar.

[0011] Preferably, a first magnetic block is provided on the front and rear sides of the rotating shaft and on the side near the connecting pipe.

[0012] Preferably, the first magnetic blocks on the same side of the rotating shaft are spaced 90 degrees apart.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. Fresh air is introduced through multiple air outlets on the upper side of the connecting pipe to form a wrap-around heat dissipation field along the cable route, achieving a uniform air cooling effect. This effectively avoids the risk of cable discoloration caused by local overheating of traditional cable trays, and significantly improves the safety of equipment operation. 2. The first support pipe, the second support pipe and the connecting pipe adopt a square tube structure. While maintaining the bending strength performance, the manufacturing cost is reduced by using standardized profiles. At the same time, a flat installation reference surface is provided for the side expansion installation of other functional components. 3. The adjustable limit system composed of the stop bar and the magnetic block achieves cable stacking height constraint through three stable working angles. Attached Figure Description

Detailed Implementation

[0015] The directional terms mentioned in the following embodiments, such as "up", "down", "left", and "right", are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustration and not for limiting the invention of this utility model.

[0016] like Figure 1-3As shown, a new type of cable tray includes a first support pipe 1 and a second support pipe 2 arranged in parallel for supporting and connecting an external air source. Multiple connecting pipes 3 for upward cable support are spaced apart between the first support pipe 1 and the second support pipe 2. The upper end face of the connecting pipe 3 is lower than the upper end face of the first support pipe 1 and the second pipe. The connecting pipe 3 is interconnected with the first support pipe 1 and the second support pipe 2. Multiple air outlets 4 for air-cooling cables are provided on the upper side of the connecting pipe 3, allowing cold air to form a wraparound heat dissipation field along the cable direction, effectively eliminating the hidden danger of local overheating in traditional cable trays. This is especially suitable for large-scale textile finishing equipment, such as tenter frame machines, where there are many lines and high ambient temperatures. Installing this new type of cable tray can solve many unsafe factors such as line discoloration due to heat, ensuring the safe operation of production equipment.

[0017] Specifically, a blower with an appropriate air volume can be selected as an external air source based on the length of the first support pipe 1 and the second support pipe 2. For example, if the length of the cable tray is within 50 meters, a blower of about 7.5kW can be selected for blowing and cooling. The air outlet 4 of the blower can be connected to one or both of the first support pipe 1 and the second support pipe 2.

[0018] Specifically, the end of the first support pipe 1 is fixedly connected to a first fixing plate 51, and the side of the first fixing plate 51 is provided with screw holes 6 for fixing with bolts, so that the first support pipe 1 can be firmly installed and fixed on the inner wall of the factory or the equipment frame; similarly, the end of the second support pipe 2 is fixedly connected to a second fixing plate 52, and the side of the second fixing plate 52 is provided with screw holes 6 for fixing with bolts.

[0019] Specifically, the first support pipe 1, the second support pipe 2, and the connecting pipe 3 are all made of square tubing. This ensures bending strength while reducing production costs and facilitates the installation and expansion of other components on their sides.

[0020] Specifically, the lower end face of the connecting tube 3 is flush with the lower end faces of the first support tube 1 and the second tube, and the upper part of the connecting tube 3 forms a hollowed-out groove with the first support tube 1 and the second support tube 2, which facilitates the management and storage of cables.

[0021] Furthermore, a rotating shaft 7 is fixedly connected to both the first support tube 1 and the second support tube 2. Each rotating shaft 7 is rotatably connected to a stop bar 8 for limiting the cable, which can constrain the stacking height of the cable. Specifically, the stop bar 8 is made of plastic and has rounded edges, making it lightweight and scratch-resistant.

[0022] Specifically, a first magnetic block 9 is installed on both the first support tube 1 and the second support tube 2. A second magnetic block 10 is installed on the lower side of the stop bar 8 to attract the first magnetic block 9. The first magnetic block 9 is also provided on the front and rear sides of the rotating shaft 7 and on the side near the connecting tube 3. The first magnetic blocks 9 on the same rotating shaft 7 are spaced 90 degrees apart, so that the stop bar 8 has three stable working angles. The angle relative to the extension direction of the first support tube 1 or the second support tube 2 is 0, 90 or 180 degrees. When it is 90 degrees, it extends towards the connecting tube 3. The length of the stop bar 8 is set so that the two stop bars 8 do not interfere with each other. This not only meets the requirements of conventional cable layer laying, but also realizes cable constraint and limitation through combination positioning, which significantly improves the space utilization of the cable tray.
