Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to an energy-saving and weather-resistant color steel molded cable tray. Background Technology

[0002] In power transmission and communication network construction projects, cable trays serve as the core carrier for supporting and protecting cables. Their performance directly affects the operational safety and service life of the cables. Color-coated steel molded cable trays are widely used due to their advantages of being lightweight, high-strength, and easy to process. Furthermore, after being coated with a weather-resistant coating, they can resist corrosion from ultraviolet rays and salt spray, aligning with the industry's development trend towards energy conservation and weather resistance. A search revealed a new energy-saving color-coated steel molded cable tray disclosed in publication number CN215897198U, comprising a left side plate, a right side plate, and a top cover plate. While this device, through color-coated steel molding, has multiple raised ribs and reinforcing ribs, offering advantages such as simple manufacturing, material saving, and high load-bearing strength, it still suffers from the following problems: The lack of dedicated cable fixing components inside the cable tray creates potential hazards after cable laying. When multiple specifications of cables are mixed together, they are prone to tangling. Subsequent maintenance requires sorting them one by one, increasing the difficulty of maintenance. More importantly, the cables are not restrained and fixed in the cable tray. They are affected by external forces such as outdoor wind vibration and vehicle bumps, and will continuously rub against the inner wall of the color steel base. This is especially serious for the PVC cable sheath, which becomes brittle in low-temperature environments. Therefore, an energy-saving and weather-resistant color steel molded cable tray is proposed. Utility Model Content

[0003] The purpose of this utility model is to solve the shortcomings of existing cable trays that do not have pre-set cable fixing components, which may lead to hidden dangers after cable laying. Therefore, this utility model proposes an energy-saving and weather-resistant color steel molded cable tray.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An energy-saving and weather-resistant color steel molded cable tray includes a cable tray body, and a detachable U-shaped cover plate is snapped onto the top of the cable tray body; Multiple wire clamp mounting bases are fixedly connected to the top of the cable tray body. Each wire clamp mounting base has multiple wire clamp slots on its top. Each wire clamp slot has a wire clamp cover plate fixedly connected to its top. Fixing screws slide through both sides of the top of the multiple wire clamp cover plates. The fixing screws pass through the wire clamp cover plates and are threadedly connected to the wire clamp mounting base. Multiple rubber pads are fixedly connected to the wire groove clamping side of the multiple wire clamp mounting seats and multiple wire clamp cover plates.

[0005] In one possible design, the cable tray body includes a base plate and two side plates. The bottom of the base plate is molded with multiple raised ribs I, and the middle of each raised rib I is molded with multiple raised ribs II. The sides of the two side plates are molded with multiple reinforcing ribs and multiple raised ribs III.

[0006] In one possible design, the bottom of the base plate has multiple pairs of positioning holes, and the bottom of multiple wire clamp mounting bases is fixedly connected to a pair of snap-fit ​​bosses that mate with the positioning holes. The snap-fit ​​bosses consist of a central connecting rod and a bottom arc head. The central connecting rod is clearance-fitted with the positioning hole, and the bottom arc head is interference-fitted with the positioning hole. The wire clamp mounting bases and the base plate are fixedly connected by inserting the snap-fit ​​bosses into the positioning holes.

[0007] In one possible design, the top of both side panels is bent with a U-shaped flange, and multiple mounting holes are provided on the sides of both side panels near the ends.

[0008] In one possible design, the cable tray body and U-shaped cover are formed by color steel molding, while the wire clamp mounting base and wire clamp cover are formed by PA6 injection molding.

[0009] In one possible design, the rubber pads are made of weather-resistant rubber, and the surfaces of the cable tray body and the U-shaped cover plate are coated with a weather-resistant coating.

[0010] In this application: The cables are first laid on the base plate of the cable tray body. Then, a detachable U-shaped cover plate is snapped onto the top of the base frame to form a closed cable channel, which plays a basic role in bearing, protecting and shielding. During cable laying, one or more cables are placed in the specific clamp slots of the clamp mounting base, and then the clamp cover plate is closed, so that the cable is wrapped in the clamp slot and the cable groove. By tightening the fixing screw that passes through the clamp cover plate and is threaded to it, the cable can be pressed and fixed by the cooperation between the clamp cover plate and the clamp mounting base. At the same time, the rubber pad is squeezed, and its elastic deformation provides cushioning protection for the cable, increases friction to prevent slippage, and also provides good insulation. The wire clamp mounting base is made of PA6 injection molding, which has high strength and toughness. The middle connecting rod of the snap-fit ​​boss is fitted with the positioning hole with a clearance fit, which facilitates the initial insertion and positioning. The bottom arc head adopts an elastic structure. When inserted, it is squeezed and contracted by the positioning hole. After being fully inserted, it rebounds and forms an interference fit with the positioning hole, realizing the automatic locking of the wire clamp mounting base. The heat generated during cable operation is primarily conducted outwards through the excellent thermal conductivity of the color steel base frame and the U-shaped cover plate. Secondly, the protruding ribs I and II, molded at the bottom of the base plate, significantly increase the heat dissipation area in contact with air, improving heat dissipation efficiency and reducing the cable's operating temperature. This reduces energy waste caused by line loss, achieving energy-saving effects. The cable tray is exposed to the environment as a whole. Its molded reinforcing ribs, raised ribs III, and U-shaped flanges on the top of the side plates work together to significantly enhance the structural strength and rigidity, and resist wind load, snow load and external force deformation. At the same time, the color steel base frame, the weather-resistant treatment of the cover plate surface, and the PA6 material wire clamps and weather-resistant rubber pads ensure long-term durability and reliability.

[0011] Beneficial effects: In this utility model, the energy-saving and weather-resistant color steel molded cable tray, through the coordinated use of components such as clamp mounting base, clamp cover plate, rubber pad, and snap-fit ​​boss, relies on the clamp slot of the clamp mounting base to lay the cable in an orderly manner, which is convenient for later maintenance. The clamp assembly is equipped with a rubber pad to fix the cable, so that the cable has no lateral displacement, preventing the cable from contacting and rubbing against the inner wall of the color steel base, and will not damage the surface of the cable. In this utility model, the energy-saving and weather-resistant color steel molded cable tray uses components such as snap-fit ​​boss, base plate, positioning hole, and wire clamp mounting seat for cooperation. The wire clamp mounting seat achieves quick fixation through the interference fit between the snap-fit ​​boss and the positioning hole of the base plate. The bottom arc head elastically retracts and automatically springs back to lock after being inserted into the positioning hole, saving time in fixing cables. In this utility model, by tightening the fixing screws that are threadedly connected to the through-clamp cover plate, the cable can be pressed and fixed by the cooperation between the clamp cover plate and the clamp mounting base. At the same time, the rubber pad is squeezed, and its elastic deformation provides buffer protection for the cable, increases friction to prevent slippage, and ensures that the cable is laid neatly and is not easy to shake and wear.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] In one implementation case, refer to Figures 1-3 A cable tray includes: a tray body 1, with a detachable U-shaped cover plate 2 snapped onto the top of the tray body 1; In this embodiment, multiple wire clamp mounting bases 3 are fixedly connected to the top of the cable tray body 1. Each wire clamp mounting base 3 has multiple wire clamp slots on its top. Each wire clamp slot has a wire clamp cover plate 4 fixedly connected to its top. Fixing screws 41 slide through both sides of the top of the multiple wire clamp cover plates 4. The fixing screws 41 pass through the wire clamp cover plates 4 and are threadedly connected to the wire clamp mounting base 3. In particular, multiple rubber pads 5 are fixedly connected to the wire groove clamping side of multiple wire clamp mounting bases 3 and multiple wire clamp cover plates 4. The rubber pads 5 form a flexible wrapping layer for the cable, which not only enhances the clamping stability, but also avoids direct contact between the cable and metal parts, thus preventing wear on the cable sheath.

[0016] It should be noted that the main body 1 of the cable tray includes a base plate 11 and two side plates 12. The bottom of the base plate 11 is molded with multiple protruding ribs I111, and the middle of each protruding rib I111 is molded with multiple protruding ribs II112. The sides of the two side plates 12 are molded with multiple reinforcing ribs 121 and multiple protruding ribs III124, which improves the structural strength and deformation resistance of the side plates 12 and the base plate 11.

[0017] This application can be used in the field of cable tray technology, or in other fields applicable to this application.

[0018] In another implementation case, refer to Figures 1-3 An energy-saving and weather-resistant color steel molded cable tray is applied to the field of cable tray technology. The bottom of the base plate 11 has multiple pairs of positioning holes 113. The bottom of multiple wire clamp mounting seats 3 is fixedly connected to a pair of snap-fit ​​bosses 31 that cooperate with the positioning holes 113. The snap-fit ​​bosses 31 are composed of a middle connecting rod and a bottom arc head. The middle connecting rod is clearance-fitted with the positioning hole 113, and the bottom arc head is interference-fitted with the positioning hole 113. The wire clamp mounting seats 3 and the base plate 11 are fixedly connected by inserting the snap-fit ​​bosses 31 into the positioning holes 113. The elastic structure of the bottom arc head of the snap-fit ​​bosses 31 automatically retracts and springs back to fix when inserted into the positioning hole 113, which allows for quick installation without tools and greatly saves labor costs.

[0019] In this embodiment, the top of the two side plates 12 is bent with a U-shaped flange 122, and multiple mounting holes 123 are opened on the sides of the two side plates 12 near both ends. The U-shaped flange 122 can guide alignment and be locked with the bolts in the mounting holes 123 to achieve quick docking and installation.

[0020] In particular, the cable tray body 1 and the U-shaped cover plate 2 are formed by color steel molding. The high ductility of the color steel allows the ribs, folded edges and other structures to be formed in one piece, which is simple to process and the lightweight color steel reduces steel consumption. The wire clamp mounting base 3 and the wire clamp cover plate 4 are formed by PA6 injection molding, which is impact resistant and has high toughness.

[0021] It should be noted that the rubber pad 5 is made of weather-resistant rubber, and the surfaces of the cable tray body 1 and the U-shaped cover plate 2 are coated with a weather-resistant coating to extend the service life of the equipment and reduce maintenance costs.
