Description
Technical Field
[0001] This utility model relates to the field of cable tray technology, and in particular to a ladder-type cable tray. Background Technology
[0002] Ladder-type cable trays are commonly used support and protection devices in cable laying projects. They belong to the field of cable tray technology. Their core structure is usually composed of side plates, base plates, crossbeams, and other components, and the whole structure is in the form of a ladder. They are mainly used in power systems, building projects, communication networks, and other scenarios to support, fix, and protect cables. At the same time, they facilitate the laying, inspection, and maintenance of cables by construction personnel, ensuring that cables are not affected by external environmental interference during long-term use and guaranteeing the stability of power or signal transmission.
[0003] The supporting components of existing cable trays are mostly straight plate structures, which are prone to stress concentration when subjected to force. Furthermore, the ends lack special reinforcement designs. When handling, installing, or carrying heavy cables for a long time, problems such as side plate deformation and crossbeam loosening are likely to occur, affecting the overall load-bearing capacity. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a ladder-type cable tray, which solves the problems mentioned in the background section.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A ladder-type cable tray includes: two sets of side plates, with a base plate welded to the bottom of the two sets of side plates on their adjacent sides. The base plate and the two sets of side plates are perpendicular to each other. A support beam is fixed between the base plate and the two sets of side plates, and the support beam is located below the base plate. The bottom end of the support beam is arc-shaped, and both ends of the support beam have through holes. A top cover is movably engaged at the top of the side plate, and a partition for separating cables is provided inside the side plate. Ventilation components are also provided on the two sets of side plates, including a filter cartridge and a cooling fan.
[0006] According to the ladder-type cable tray, each of the two sets of side plates has a sliding groove on the side away from each other, the top cover is U-shaped, and the two ends of the top cover are movably engaged with the corresponding sliding groove. Each of the two sets of side plates has a fixed pile installed on the side away from each other.
[0007] According to the ladder-type cable tray, a buffer pad is attached and fixed to the top of the base plate, and multiple sets of crossbeams are welded and fixed between the two sets of side plates, with the multiple sets of crossbeams located above the buffer pad.
[0008] According to the ladder-type cable tray, multiple sets of partitions are located between adjacent crossbeams on both sides of the side plate, and the two ends of the partitions are fixedly connected to the crossbeams by screws.
[0009] According to the ladder-type cable tray, two sets of reinforcing rods are welded and fixed between the two sets of side plates. The two sets of reinforcing rods are on the same plane as the crossbeam, and the two sets of reinforcing rods are located at both ends of the side plates respectively.
[0010] According to the ladder-type cable tray, two sets of first sleeves are embedded in the side plate at the front end, and the filter cartridges are snapped into the corresponding first sleeve cavities. Fixing plates are fixedly installed on both sides of the filter cartridges, and the fixing plates are fixed to the first sleeves by screws.
[0011] According to the ladder-type cable tray, a second sleeve is embedded in the middle of the side plate at the rear end, and a cooling fan is installed in the cavity of the second sleeve. The cooling fan is powered by the mains power.
[0012] This utility model provides a ladder-type cable tray. It has the following advantages: (1) The two sets of side plates are welded to the bottom plate to form a "U"-shaped main support frame. With the support beam fixed between the bottom plate and the side plate, the connection strength between the bottom plate and the side plate is strengthened and the upper limit of the load-bearing capacity of the bottom plate is increased. The pressure is also dispersed by the arc structure at the bottom of the support beam to avoid stress concentration. At the same time, the two sets of reinforcing rods fixed to both ends of the side plate can prevent the cable tray end from deforming during handling or use. The multiple sets of crossbeams are connected to the side plate laterally to further enhance the lateral stiffness and assist in supporting the cable, avoiding damage to the cable due to the span. Overall, the stability of the cable tray structure is significantly improved, preventing displacement or deformation during use and extending the service life of the device.
[0013] (2) By attaching a buffer pad to the top of the base plate, the elastic material reduces the hard contact wear between the cable and the base plate during cable laying, and at the same time alleviates the slight vibration during cable operation, and avoids damage to the cable sheath due to friction; the partition in the side plate is fixed between the adjacent crossbeams with screws, which can divide the inside of the cable tray into multiple independent areas, making it convenient to lay cables of different specifications and uses in different categories, effectively preventing maintenance difficulties caused by cables tangling together, as well as signal interference between power cables and control cables, and ensuring stable cable operation; and the sliding groove on the outside of the top cover and the side plate can be engaged, which is convenient for quick disassembly and assembly for cable maintenance, and can also block the intrusion of external dust and water droplets, providing all-round protection for the cable.
[0014] (3) By embedding and installing the first sleeve in the front side plate, the filter cartridge is snapped into the cavity of the first sleeve and fixed by the screws of the fixing plate. The air filter element in the filter cartridge can filter the external dust while ensuring the air circulation inside the cable tray, and avoid dust adhering to the cable surface to form a heat insulation layer that affects heat dissipation. The second sleeve is embedded and installed in the rear side plate, and the cooling fan powered by the mains is installed in the cavity of the second sleeve. It can actively exhaust air to accelerate the air circulation inside the cable tray, quickly remove the heat generated by the cable operation, effectively solve the problem of excessive temperature in the enclosed area, and is especially suitable for dense cable laying or high temperature environment. It can significantly extend the service life of the cable, reduce the risk of cable failure caused by overheating, and at the same time ensure that the dustproof and heat dissipation functions are stable and reliable.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0018] Please see Figure 1-5As shown, this utility model is a ladder-type cable tray, including side plates 10, of which there are two sets. A base plate 11 is welded and fixed to the bottom end of the two sets of side plates 10 that are close to each other. The two sets of side plates 10 and the base plate 11 form the main support frame of the cable tray, providing vertical support for the overall structure and providing lateral protection for the cables laid inside. The base plate 11 is perpendicular to the two sets of side plates 10. A support beam 14 is fixed between the base plate 11 and the two sets of side plates 10. The support beam 14 is located below the base plate 11. The bottom end of the support beam 14 is arc-shaped, and both ends of the support beam 14 have through holes. By setting the support beam 14, the connection strength between the base plate 11 and the two sets of side plates 10 is strengthened, and the upper limit of the load-bearing capacity of the base plate 11 is increased. The arc-shaped bottom end of the support beam 14 can distribute the pressure on the support beam 14, avoid stress concentration, and improve the service life of the device.
[0019] like Figure 2 and 3 As shown, each of the two sets of side plates 10 has a sliding groove 18 on the side away from each other. The top cover 12 is U-shaped, and its two ends are movably engaged with the corresponding sliding groove 18, facilitating the installation and removal of the top cover 12 and preventing external dust, impurities, or water droplets from falling in. Each of the two sets of side plates 10 has a fixed fixing pile 13 on the side away from each other, facilitating the hoisting of the cable tray. A buffer pad 15 is attached and fixed to the top of the bottom plate 11. Multiple sets of crossbeams 16 are also welded and fixed between the two sets of side plates 10, located above the buffer pad 15. By attaching and fixing the buffer pad 15 to the top of the bottom plate 11, the hard contact wear between the cable and the bottom plate 11 can be reduced during cable laying, while mitigating slight vibrations during cable operation and preventing damage to the outer sheath caused by friction between the cable and the bottom plate 11. The crossbeams 16 strengthen the lateral connection strength of the two sets of side plates 10, improving the structural stability of the device.
[0020] like Figure 3 As shown, a top cover 12 is movably engaged at the top of the side plate 10. Inside the side plate 10, partitions 17 are provided for separating cables. Multiple sets of partitions 17 are located between adjacent crossbeams 16 on both sides of the side plate 10. The two ends of the partitions 17 are fixedly connected to the crossbeams 16 by screws. Two sets of reinforcing rods 19 are welded and fixed between the two sets of side plates 10. The two sets of reinforcing rods 19 are on the same plane as the crossbeams 16, and are located at both ends of the side plate 10. By setting up partitions 17, multiple areas can be divided according to the number of cables, facilitating cable classification and preventing cables from tangling or interfering with signals. The screw fixing method makes installation and disassembly more convenient. The reinforcing rods 19 installed on both sides of the side plate 10 are used to strengthen the structural stability of the cable tray ends and prevent deformation of the cable tray ends during handling or use.
[0021] like Figure 4-5As shown, two sets of first sleeves 20 are embedded in the front side plate 10. Filter cartridges 21 are snapped into the corresponding cavities of the first sleeves 20. Fixing plates 22 are fixedly installed on both sides of the filter cartridges 21, and the fixing plates 22 are fixed to the first sleeves 20 with screws. A second sleeve 23 is embedded in the middle of the rear side plate 10, and a cooling fan 24 is installed in the cavity of the second sleeve 23. The cooling fan 24 is powered by AC power. By embedding and installing two sets of first sleeves 20 on the front side plate 10, filter cylinders 21 are installed in the corresponding first sleeves 20. The filter cylinders 21 are filled with air filter elements to filter dust in the air. By embedding and installing a second sleeve 23 on the rear side plate 10, a cooling fan 24 is installed in the second sleeve 23. The cooling fan 24 actively exhausts air, accelerates the air circulation inside the cable tray, and can quickly remove the heat generated by the cable during operation. This solves the problem of excessive temperature in the enclosed area of the cable tray. It is especially suitable for use in scenarios where cables are densely laid or in high-temperature environments, significantly extending the service life of the cable and reducing the risk of cable failure due to overheating.
[0022] The implementation principle of this utility model of a ladder-type cable tray is as follows: First, the two sets of side plates 10 are connected to the base plate 11 by welding to form a stable "U"-shaped foundation frame. Then, the support beam 14 is fixed below the base plate 11 and between the two sets of side plates 10. At the same time, the connection between the cable tray and the external support structure is further strengthened by the fixing piles 13 on the outside of the two sets of side plates 10. This ensures that the main frame remains stable in subsequent operations and long-term use, avoids displacement or deformation, and lays a structural foundation for subsequent cable laying.
[0023] Secondly, a buffer pad 15 is attached to the top of the base plate 11 to provide a protective pad for the cable through an elastic material. Then, multiple sets of crossbeams 16 are welded between the two sets of side plates 10 to enhance the lateral support strength and prevent the cable from sagging. At the same time, partitions 17 are fixed between adjacent crossbeams 16 with screws to divide the inside of the cable tray into multiple independent areas. Then, according to the cable specifications and uses, different types of cables are laid in the areas divided by the partitions 17 to prevent the cables from getting tangled and to avoid signal interference between cables of different uses, ensuring that the cable laying is neat and the operation is stable.
[0024] Finally, the top cover 12 is first engaged with the sliding grooves 18 on the outer side of the side plate 10, and the U-shaped structure of the top cover 12 blocks external dust and water droplets from entering the cable tray. Then, the filter cartridge 21 is engaged and installed in the first sleeve 20 cavity of the front side plate 10, and fixed with the fixing plate 22 and screws. The air entering the cable tray is filtered by the air filter element in the filter cartridge 21. At the same time, the cooling fan 24 is installed in the second sleeve 23 cavity of the rear side plate 10 and connected to the mains power. The cooling fan 24 actively exhausts air to accelerate the internal air circulation, removes the heat generated by the cable operation, and finally forms a complete protection system for protection, heat dissipation and dust prevention, which extends the service life of the cable and reduces the risk of failure.
[0025] The above embodiments are preferred implementations of this utility model. In addition, this utility model can be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
