Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a long-span, high-strength cable tray. Background Technology

[0002] Cable trays are structural facilities used to support, manage, and protect power cables and telecommunications cables. They are made of metallic or non-metallic materials and are used in industrial, commercial, and building projects. Cable trays ensure the safety and stability of cables and reduce damage to cables from external factors by providing support and protection.

[0003] Traditional cable trays are installed using bolts, requiring multiple bolts for each section. This is time-consuming, especially during high-altitude operations such as ceiling installations, and bolts can be lost or rusted, affecting later disassembly and maintenance. Current solutions employ quick-connect structures with clips and positioning pins. The cable tray ends feature protruding clips and grooves; simply align and insert them to lock them in place, with spring pins preventing them from falling off. This shortens installation time per section and eliminates the need for tools, making it suitable for high-altitude work. However, the cable trays still have the potential to deform under high temperatures, failing to effectively protect the cables. Furthermore, in humid environments, the cable trays can rust over time, leading to reduced structural strength, lower weather resistance, and shortened service life. Utility Model Content

[0032] The weather-resistant structure 2 includes a reinforcing layer 201. The top wall of the reinforcing layer 201 is fixedly connected to the inner top wall of the fluorocarbon coated frame 1. The fluorocarbon coated frame 1 can improve the salt spray resistance of the cable tray. Multiple connecting ribs 203 are fixedly connected to the front side of the inner wall of the reinforcing layer 201, and multiple reinforcing ribs 202 are fixedly connected to the right side of the inner wall of the reinforcing layer 201. With the connection of multiple connecting ribs 203 and reinforcing ribs 202, the impact resistance of the inside of the reinforcing layer 201 can be improved, thereby extending the service life of the cable tray. A gel board 204 is fixedly connected to the bottom of the reinforcing layer 201. With the connection of the gel board 204, the heat insulation effect inside the fluorocarbon coated frame 1 can be improved, reducing the influence of external temperature on the inside of the cable tray. A rock wool board 205 is fixedly connected to the bottom of the gel board 204. A pressure-resistant component 206 is provided at the bottom of the rock wool board 205. The pressure-resistant component 206 can improve the resistance of the cable tray to external pressure.

[0033] The compression-resistant component 206 includes two fixing plates 2061. The top walls of the two fixing plates 2061 are fixedly connected to the bottom of the rock wool board 205. The fixing plates 2061 can be connected by multiple connecting blocks 2062. Multiple connecting blocks 2062 are fixedly connected between adjacent fixing plates 2061. Multiple carbon fiber columns 2063 are fixedly connected to the bottom of the fixing plates 2061. Subsequently, the compression resistance effect inside the cable tray is improved by the connection of multiple carbon fiber columns 2063.

[0034] Specifically, in the weather-resistant mechanism 2 inside the fluorocarbon coated frame 1, multiple connecting ribs 203 are fixed to the front side of the inner wall of the reinforcing layer 201 fixed to the inner top wall, and multiple reinforcing ribs 202 are fixed to the right side of the inner wall. The connecting ribs 203 and the reinforcing ribs 202 are connected to improve the impact resistance of the reinforcing layer 201 and extend the service life of the cable tray. The gel board 204 fixed to the bottom of the reinforcing layer 201 improves the internal heat insulation effect and reduces the damage to the inside of the fluorocarbon coated frame 1 caused by external temperature. The rock wool board 205 fixed to the bottom of the gel board 204 is the bottom anti-compression component 2. In section 06, two fixing plates 2061 are fixed to the top wall of the rock wool board 205. Multiple connecting blocks 2062 are fixed between adjacent plates to connect the fixing plates 2061. Multiple carbon fiber columns 2063 are fixed to the bottom of the fixing plates 2061 to improve the internal pressure resistance of the cable tray to resist external pressure. The support frame 3 fixed in the middle of the inner wall of the fluorocarbon coated frame 1 fixes the high-voltage cables. The connecting frame 4 fixed on the front and rear sides of the inner wall connects to the support mechanism 5 of the inner wall. The support mechanism 5 improves the deformation resistance of the fluorocarbon coated frame 1. The fluorocarbon coated frame 1 itself improves the salt spray resistance of the cable tray.

[0035] Reference Figure 1 , Figure 2 and Figure 5 The support mechanism 5 includes two support frames 501. The outer walls of the two support frames 501 are fixedly connected to the inner walls of the corresponding connecting frames 4. The connection of the support frames 501 can effectively improve the deformation resistance of the fluorocarbon coated frame 1. A fixing rod 502 is fixedly connected to the middle of the inner wall of the support frame 501. Diagonal braces 505 are fixedly connected to the top left and right sides of the fixing rod 502. The stability of the support frame 501 can be further improved by the connection of the fixing rod 502 and the diagonal braces 505. A partition plate 503 is fixedly connected between the adjacent two connecting frames 4. The weak current cables can be placed in partitions through the partition plate 503 and the side baffle 504. Side baffles 504 are fixedly connected to the left and right sides of the partition plate 503. A limit component 507 is provided in the middle of the top wall of the support frame 3. The limit component 507 is used to limit and fix the cables. A reinforcing component 509 is provided on the front side of the partition plate 503.

[0036] Specifically, the connection of the support frame 501 effectively improves the internal deformation resistance of the fluorocarbon coated frame 1. The connection between the fixed rod 502 and the diagonal brace 505 and the fixed rod 502 further improves the stability of the support frame 501. The side baffle 504, together with the partition plate 503, allows for the partitioning of low-voltage cables. The limiting component 507 in the middle of the top wall of the support frame 3 limits and fixes the cables. The reinforcing component 509 on the front side of the partition plate 503 assists in reinforcing the structure. Overall, the structural performance and usage effect of the fluorocarbon coated frame 1 are improved in a coordinated manner.

[0037] Reference Figure 1 , Figure 4 and Figure 5The limiting component 507 includes multiple sliding limiting plates 5071. The outer walls of the multiple sliding limiting plates 5071 are set inside the support frame 3. Limiting grooves 5072 are opened at the upper and lower ends of the front side of the sliding limiting plates 5071. Two sliding grooves 5073 are opened on the left and right sides of the top wall of the support frame 3. The outer walls of the multiple sliding limiting plates 5071 are slidably connected to the corresponding sliding grooves 5073. A cable management rack 5074 is fixedly connected between adjacent sliding limiting plates 5071. The reinforcing component 509 includes two reinforcing plates 5091. The outer walls of the two reinforcing plates 5091 are fixedly connected to the bottom front side of the support frame 501. Connecting grooves 5092 are opened at the left and right ends of the front side of the partition plate 503. The outer walls of the two reinforcing plates 5091 are engaged with the connecting grooves 5092. Multiple reinforcing ribs 202 and multiple connecting ribs 203 are fixedly connected and form a rectangular grid structure.

[0038] Specifically, by sliding the limiting plate 5071, the two limiting grooves 5072 can respectively limit and fix the high-voltage cable and the low-voltage cable. At the same time, the cable management rack 5074 performs the limiting work simultaneously. The reinforcing plate 5091 can improve the internal support effect of the partition plate 503 and increase its service life. The reinforcing ribs 202 and the connecting ribs 203 form a rectangular grid structure, which improves the internal toughness of the reinforcing layer 201.

[0039] Reference Figure 1 , Figure 2 and Figure 5 The support mechanism 5 also includes multiple heat dissipation slots 508, which are respectively opened in the middle of the top wall of the support frame 3; the top of the outer wall of the two support frames 501 are fixedly connected with connecting columns 506, and the middle of the two connecting columns 506 passes through the middle of the left and right sides of the connecting frame 4.

[0040] Specifically, the heat dissipation effect inside the structure can be improved by multiple heat dissipation slots 508, and the front and rear support frames 501 can be connected by connecting columns 506, thereby improving the stability during use.

[0041] Working principle: The fluorocarbon coated frame 1 itself can improve the salt spray resistance of the cable tray. The support frame 3 fixed in the middle of the inner wall fixes the high-voltage cables. The connecting frame 4 fixed on the front and rear sides of the inner wall connects to the support mechanism 5. The support mechanism 5 improves the deformation resistance of the fluorocarbon coated frame 1. The reinforcing layer 201 fixed on the inner top wall of the fluorocarbon coated frame 1 has multiple connecting ribs 203 fixed on the front side of its inner wall connected to multiple reinforcing ribs 202 fixed on the right side of the inner wall, which improves the internal impact resistance. The gel board 204 fixed at the bottom of the reinforcing layer 201 improves the internal heat insulation effect and reduces the influence of external temperature. The rock wool board 205 fixed at the bottom enhances the fire resistance. In the pressure-resistant component 206 at the bottom of the rock wool board 205, two fixed plates 2061 are connected by multiple connecting blocks 2062 fixed between adjacent parts. The multiple carbon fiber columns 2063 fixed at the bottom improve the internal pressure resistance of the cable tray and resist external pressure. Through the synergy of the above structures, the internal impact resistance of the cable tray is increased, the service life is improved, the fire resistance and heat insulation performance are enhanced, and the situation of reduced structural strength and low weather resistance is avoided.

[0042] Furthermore, the support frame 501, in conjunction with the partition plate 503, provides stress dispersion support for the interior of the fluorocarbon coated frame 1. Simultaneously, the diagonal braces 505 fixed to the top left and right sides of the fixed rod 502, connected to the fixed rod 502, further enhance the stability of the support frame 501, effectively strengthening the anti-deformation effect within the structure. The side baffles 504 fixed to the left and right sides of the partition plate 503, in conjunction with the partition plate 503, allow for the partitioning of low-voltage cables. The limiting component 507 in the middle of the top wall of the support frame 3 slides, limiting and fixing the cables, reducing instability caused by cable slippage. The reinforcing component 509 on the front side of the partition plate 503 further strengthens the structure, comprehensively improving the internal stability of the cable tray.
