Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and more specifically, to an adjustable cable tray. Background Technology

[0002] Cable trays, also known as cable supports or cable trays, are supports used to support, protect, and manage cables and wires in wiring. They are made of materials such as steel, aluminum alloy, fiberglass, and composite materials, and are devices used to support, protect, and manage cables and wires. They consist of straight sections, bends, accessories, supports, and hangers, forming a continuous, rigid structural system. Cable trays can be classified by type, including trough-type cable trays, tray-type cable trays, ladder-type cable trays, and long-span cable trays.

[0003] Ladder-type cable trays have advantages such as light weight, easy installation, good heat dissipation, and good ventilation, but they also have some limitations in practical applications. For example, their width and height are fixed and cannot be adjusted, making it difficult to adapt to different laying requirements. To solve the above problems, this utility model proposes an adjustable cable tray. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an adjustable cable tray, which solves the problems mentioned in the background section. This cable tray has an adjustable function, capable of adjusting its width and height to meet the usage requirements of different application scenarios.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An adjustable cable tray includes fixed side plates and channel steel beams. Two sets of fixed side plates are provided, with multiple sets of channel steel beams evenly distributed between the two sets of fixed side plates. A square tube insertion beam is welded and fixed to the inner side of each fixed side plate at a location corresponding to the channel steel beam. The square tube insertion beam can be inserted into the channel steel beam. A screw hole is formed on the bottom surface of the square tube insertion beam near its inner end face, and a fixing nut is welded to the upper side of the screw hole. A sliding groove is formed on the bottom surface of the channel steel beam, and a bolt passes through the sliding groove, with the bolt screwed into the fixing nut.

[0007] The fixed side plate has a C-shaped movable side plate on its outer side. The upper end of the fixed side plate is folded outward to form a U-shaped structure. Multiple sets of screws are uniformly welded and fixed inside the U-shaped structure. A through hole is opened on the bottom surface of the fixed side plate at the position corresponding to the screw, and the diameter of the through hole is larger than the diameter of the screw. The lower end of the screw extends out of the through hole, and an adjusting nut is screwed to the lower end of the screw.

[0008] Furthermore, the lower end of the fixed side plate is bent inward to form an L-shaped structure, and the bottom surface of the channel steel beam abuts against the L-shaped structure at the bottom of the fixed side plate.

[0009] Furthermore, multiple sets of rivets are evenly provided on the outer surface of the U-shaped structure of the fixed side plate, and a limiting groove is opened on the movable side plate at the position corresponding to the rivets. The rivets pass through the limiting groove and are welded to the fixed side plate, and the outer diameter of the rivet is greater than the width of the limiting groove.

[0010] Furthermore, multiple sets of slots for connecting external connectors are provided at both the front and rear ends of the fixed side plate and the movable side plate.

[0011] Furthermore, the fixed side plate, movable side plate, channel steel beam, and square tube insertion beam are all made of stainless steel and are hot-dip galvanized.

[0012] Furthermore, the surfaces of the fixed side plates, movable side plates, channel steel beams, and square tube insertion beams, after hot-dip galvanizing, are all coated with a layer of fire-retardant paint.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model achieves flexible adjustment of cable tray height by setting a retractable movable side plate on the fixed side plate. The movable side plate and the fixed side plate are slidably connected and fixed by a screw and adjusting nut, so that users can adjust the height of the cable tray as needed to adapt to different cable laying requirements.

[0015] 2. This utility model, by setting a channel steel crossbeam and a telescopic square tube insertion beam, can flexibly adjust the width of the cable tray. The square tube insertion beam can be fixed in the channel steel crossbeam by bolts and fixing nuts, achieving an adjustable fastening effect. At the same time, the sliding groove can realize the telescopic movement of the square tube insertion beam, thereby realizing the adjustment of the distance between the fixed side plates and the adjustment of the overall width of the cable tray.

[0016] 3. The L-shaped structure at the lower end of the fixed side plate of this utility model can support the channel steel beam from the contact point, which enhances the stability of the overall structure of the cable tray and provides additional support points for the channel steel beam, enabling the cable tray to withstand greater weight.

[0017] 4. This utility model forms a limiting structure for the movable side plate by using rivets and limiting grooves, which restricts the movement range of the movable side plate and prevents it from moving excessively. At the same time, it can limit the movable side plate in the horizontal direction to prevent the movable side plate from loosening laterally and ensure the connection between the movable side plate and the fixed side plate.

[0018] 5. In this utility model, the fixed side plate, movable side plate, channel steel beam, and square tube insertion beam are all made of stainless steel and are hot-dip galvanized. Stainless steel can withstand large loads and resist corrosive factors in the environment, such as moisture and chemicals, thereby extending the service life of the cable tray. The hot-dip galvanizing treatment improves the corrosion resistance of the cable tray and protects the stainless steel from corrosive factors in the environment, thus extending the service life of the cable tray.

[0019] 6. In this utility model, the fixed side plates, movable side plates, channel steel beams, and square tube insertion beams, after hot-dip galvanizing, are all coated with a layer of fire-retardant paint. This fire-retardant paint improves the fire resistance of the cable tray. Fire-retardant paint is a coating with flame-retardant and fire-resistant properties, capable of preventing the spread of flames. The application of fire-retardant paint provides an extra layer of fire protection for the cable tray, helping to reduce the likelihood of fire and minimize fire damage. Attached Figure Description

[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0029] Example:

[0030] like Figures 1 to 7 As shown, an adjustable cable tray includes fixed side plates 1 and channel steel beams 3. Two sets of fixed side plates 1 serve as the main support frame of the cable tray. Multiple sets of channel steel beams 3 are evenly distributed between the two sets of fixed side plates 1, enhancing the load-bearing capacity of the cable tray and simultaneously connecting square tube insertion beams 4 on the fixed side plates 1. Square tube insertion beams 4 are welded and fixed to the inner side of the fixed side plates 1 at locations corresponding to the channel steel beams 3. The square tube insertion beams 4 can be inserted into the channel steel beams 3 to achieve connection. The bottom surface of the square tube insertion beams 4 is close to the inner end face. A screw hole 14 is provided at the location, and a fixing nut 11 is welded to the upper side of the screw hole 14. A sliding groove 12 is provided on the bottom surface of the channel steel beam 3. A bolt 10 passes through the sliding groove 12, and the bolt 10 is screwed into the fixing nut 11. By using the bolt 10 and the fixing nut 11, the square tube insertion beam 4 can be fixed in the position of the channel steel beam 3, and an adjustable fastening effect is achieved. At the same time, the sliding groove 12 can be used to realize the telescopic movement of the square tube insertion beam 4, thereby realizing the adjustment of the distance between the fixed side plates 1 and the adjustment of the overall width of the cable tray.

[0031] The fixed side plate 1 has a C-shaped movable side plate 2 on its outer side for adjusting the height of the cable tray. The upper end of the fixed side plate 1 is folded outward to form a U-shaped structure. Multiple sets of screws 5 are uniformly welded and fixed inside the U-shaped structure. A through hole 13 is opened on the bottom surface of the fixed side plate 1 at the position corresponding to the screw 5, and the diameter of the through hole 13 is larger than the diameter of the screw 5. The lower end of the screw 5 extends out of the through hole 13, and an adjusting nut 8 is screwed to the lower end of the screw 5. By pulling the movable side plate 2 up and down, its overall height with the fixed side plate 1 can be adjusted, thereby realizing the adjustment of the overall height of the cable tray. At the same time, by adjusting the position of the adjusting nut 8 on the screw 5, the position of the movable side plate 2 can be locked, realizing the support and fixation of the movable side plate 2. This design solves the problem that the existing ladder-type cable trays have fixed width and height, cannot be adjusted, and are difficult to adapt to different laying requirements.

[0032] In this embodiment, the lower end of the fixed side plate 1 is bent inward to form an L-shaped structure. The bottom surface of the channel steel beam 3 is in contact with the L-shaped structure at the bottom of the fixed side plate 1. This design can support the channel steel beam 3 from the contact through the L-shaped structure at the lower end of the fixed side plate 1, which enhances the stability of the overall structure of the cable tray and provides additional support points for the channel steel beam 3, enabling the cable tray to withstand greater weight.

[0033] In this embodiment, multiple sets of rivets 9 are evenly arranged on the outer surface of the U-shaped structure of the fixed side plate 1. A limiting groove 7 is formed on the movable side plate 2 at a location corresponding to the rivets 9. The rivets 9 pass through the limiting groove 7 and are welded to the fixed side plate 1, with the outer diameter of the rivet 9 being larger than the width of the limiting groove 7. This design, through the rivets 9 and the limiting groove 7, forms a limiting structure for the movable side plate 2, restricting its range of movement and preventing excessive movement. Simultaneously, it can limit the movable side plate 2 horizontally, preventing lateral loosening and ensuring the stable connection between the movable side plate 2 and the fixed side plate 1.

[0034] In this embodiment, multiple sets of slots 6 for connecting external connectors are provided at both the front and rear ends of the fixed side plate 1 and the movable side plate 2. These slots 6 allow for the connection of external connectors with external bolts 10, thereby enabling connections between different cable trays while ensuring the stability of the connection.

[0035] In this embodiment, the fixed side plate 1, the movable side plate 2, the channel steel beam 3, and the square tube insertion beam 4 are all made of stainless steel and undergo hot-dip galvanizing treatment. Stainless steel is a material with high strength and excellent corrosion resistance. It can withstand large loads while resisting corrosive factors in the environment, such as moisture and chemicals, thereby extending the service life of the cable tray. Stainless steel also has good processing performance, allowing it to be easily processed into various shapes and sizes to meet the diverse design needs of cable trays. Hot-dip galvanizing improves the corrosion resistance of the cable tray. By immersing the stainless steel components in molten zinc, a zinc-iron alloy layer is formed, further enhancing the corrosion resistance of the components and protecting the stainless steel from corrosive factors in the environment, thus extending the service life of the cable tray.

[0036] In this embodiment, the surfaces of the fixed side plate 1, movable side plate 2, channel steel beam 3, and square tube insertion beam 4, after hot-dip galvanizing, are all coated with a layer of fire-retardant paint. The fire-retardant paint improves the fire resistance of the cable tray. Fire-retardant paint is a coating with flame-retardant and fire-resistant properties, capable of preventing the spread of flames. The application of fire-retardant paint provides an extra layer of fire protection for the cable tray, helping to reduce the likelihood of fire and minimize fire damage. In addition to fire resistance, the fire-retardant paint also has a certain degree of corrosion resistance, protecting the cable tray surface from corrosive factors in the environment, such as moisture and chemicals. The fire-retardant paint and the hot-dip galvanizing treatment work synergistically to improve the durability and service life of the cable tray.

[0037] The working principle of this adjustable cable tray:

[0038] In the initial state, the height and width of the cable tray are at their minimum values. When the height of the cable tray needs to be adjusted, first pull the movable side plate 2 upwards to adjust its height as needed. Then, adjust the position of the adjusting nut 8 on the screw 5 to lock the position of the movable side plate 2, thus supporting and fixing it. When the width of the cable tray needs to be adjusted, loosen the bolts 10 on the bottom surface of the channel steel beam 3, then pull the fixed side plate 1 outwards to move the position of the square tube insertion beam 4 in the channel steel beam 3 as needed. Then, tighten the bolts 10. The bolts 10, in conjunction with the fixing nut 11, secure the square tube insertion beam 4, thus adjusting the width of the cable tray.

[0039] In summary, this adjustable cable tray can easily adjust its width and height to adapt to different laying requirements, while also having good structural stability and fire and corrosion resistance, thus extending the service life of the cable tray.

[0040] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
