Description

Technical Field

[0001] The utility model relates to the technical field of power supply and distribution, in particular to an assembled hoisting wiring bridge. Background Art

[0002] Cable trays are a system structure used to support and protect cables and wires, and are widely used in industries such as petroleum, chemical engineering, urban construction, power generation, and telecommunications. Typically constructed from metal materials such as steel or aluminum to ensure sufficient strength and durability, cable trays are designed to facilitate cable installation, maintenance, and management while minimizing physical and electromagnetic interference between cables, ensuring the safe, orderly, and efficient operation of electrical systems.

[0003] However, existing cable trays often have simple structures, typically constructed from a simple combination of steel rods or steel plates. These structures often struggle to achieve a high degree of standardization and modularity. Furthermore, they suffer from shortcomings in structural strength, stability, and functional scalability, making them difficult to meet the demands of increasingly complex industrial environments and diverse needs. This is particularly true in large factories and high-rise buildings, which place higher demands on cable trays' load-bearing capacity, ease of installation, and adaptability. Utility Model Content

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0022] See also Figure 1 A preferred embodiment of an assembled hoisting cable tray is provided. In this embodiment, the assembled hoisting cable tray includes a basic cable tray 5, an extended cable tray 6, and a reinforced bottom liner 7. The number of extended cable trays 6 can be 0 to 3. When the number of extended cable trays 6 is 0, the reinforced bottom liner 7 is directly assembled on the bottom surface of the basic cable tray 5. When the number of extended cable trays 6 is 1, the assembly style is as follows: Figure 1 As shown, when there are 2 or 3 extended bridges 6, when assembling, multiple extended bridges 6 are stacked up and down, and as shown in FIG. Figure 1 The position of the extended bridge 6 shown is used to replace the original extended bridge 6 which was only one.

[0023] The main body of the basic bridge 5 is a first U-shaped frame, which includes side guards 9 on both sides and a horizontal shelf 11. The side guards 9 are formed with structural protrusions 2 on both sides of the top, and these structural protrusions 2 are formed with through-holes for mounting the hanging rod 1. The side guards 9 on both sides of the basic bridge 5 are formed with outwardly protruding male buckle parts 19 on the lower outer sides.

[0024] The main body of the extended bridge frame 6 is composed of a second U-shaped frame. The structural form of the second U-shaped frame at this height is similar to that of the first U-shaped frame. The height of the second U-shaped frame is 1 / 2 of the height of the first U-shaped frame (corresponding to the height of the side guards 9 on both sides); the bottom size is consistent with the bottom size of the basic bridge frame 5, and the extended bridge frame 6 has a docking part on the upper part of the second U-shaped frame that matches the bottom of the basic bridge frame 5, and there are female buckle parts 17 on both sides of the docking part that match the male buckle parts 19.

[0025] In this embodiment, the base bridge 5 and the extended bridge 6 are both integral structures formed by continuously bending galvanized cold-rolled steel sheets. The base bridge 5 remains open on the top surface of the first U-shaped frame, and this open surface is closed by the mating fastening of the outer buckle plate 4 and the snap protrusions 8.

[0026] The basic bridge frame 5 is formed with multiple ribs 3 as reinforcement structures at the inner connection positions of the side blocks 9 on both sides and the cross shelves 11. The multiple ribs 3 are arranged at equal intervals along the length direction of the basic bridge frame 5, which can effectively improve the overall rigidity and torsional resistance of the bridge frame.

[0027] In this embodiment, in order to facilitate the stacking of the extended bridge frames 6 on each other, the stacking of the extended bridge frames 6 on the bottom surface of the basic bridge frame 5, and the stacking of the reinforced base liner 7 on the bottom surface of the basic bridge frame 5 or the extended bridge frame 6, the extended bridge frame 6 and the reinforced base liner 7 are both formed with an inward step structure at the bottom position, so as to form a staggered and matching mounting step surface with the top surface of the extended bridge frame 6 and the top surface of the reinforced base liner 7 through the inward step structure, so as to achieve a stable connection and a good sealing effect.

[0028] The reinforcing base liner 7 has a downwardly convex arc-shaped structure 14, and has an outer cover edge 15 that can cover the bottom position of the basic bridge 5 / extended bridge 6 from the bottom. The arc-shaped structure 14 and the outer cover edge 15 are transitionally connected by a right-angle step, and the reinforcing base liner 7 is provided with female buckles 17 that match the male buckles 19 on both sides of the outer cover edge 15. In addition, the reinforcing base liner 7 is formed with a plurality of vertical partitions 13 arranged at intervals on the inner side of the arc-shaped structure 14. The vertical partitions 13 can be pressed against the bottom of the corresponding basic bridge 5 / extended bridge 6 after the reinforcing base liner 7 is covered. At the same time, cushioning material pads 12 are also formed on the top surface of the vertical partitions 13. These pads 12 can effectively reduce the direct contact between the reinforcing base liner 7 and the basic bridge 5 or the extended bridge 6, thereby reducing the transmission of vibration and noise, and improving the stability and service life of the overall structure.

[0029] To further improve the efficiency of bridge installation and disassembly, the joints between the base bridge 5 and the extended bridge 6, as well as the joints between the reinforced base 7 and the extended bridge 6, are designed with a quick-locking mechanism. This quick-locking mechanism includes a fixed buckle 10 on one side of the structure and a movable buckle 16 on the other side. Both the fixed buckle 10 and the movable buckle 16 include matching male and female buckle portions 19 and 17. The only difference between them is that the female buckle 17 of the fixed buckle 10 is a fixed structure, while the female buckle 17 of the movable buckle 16 is a movable structure.

[0030] As an example of assembly, when the extended bridge 6 is assembled on the bottom surface of the basic bridge 5, the female buckle 17 of the fixed buckle 10 is first fastened to the male buckle 19 on the corresponding side of the basic bridge 5 on the right side of the extended bridge 6. Then, the female buckle 17 of the movable buckle 16 is fastened to the male buckle 19 on the corresponding side of the basic bridge 5 on the left side, completing the fixed assembly of the extended bridge 6. Correspondingly, when stacking and assembling other extended bridges 6 below the extended bridge 6, or when stacking and assembling the reinforcing base 7 on the bottom surface of the basic bridge 5 / extension bridge 6, it is only necessary to refer to the above assembly method.

[0031] In addition, in the quick locking mechanism, a keyhole 18 is provided on the left male buckle 19 and the female buckle 17. By inserting a structural lock body or a lead seal into the keyhole, unauthorized disassembly and tampering can be effectively prevented, ensuring the integrity of the bridge system and the safety of the cables.

[0032] In the technical solution of this embodiment, the inner cavities of the basic bridge 5 and the extended bridge 6 and the compartments between the vertical partitions 13 on the inner side of the reinforced base 7 can all be used as cable routing spaces. When the number of cables is small and does not require classification / separation, only the basic bridge 5 or the combination of the basic bridge 5 and the reinforced base 7 can be set. When the number of cables that need to be routed is large, or the cables need to be classified / separated, a combination of the basic bridge 5 and the extended bridge 6 can be used, or even multiple extended bridges 6 can be added to meet and adapt to the routing needs of cables of different scales and complexities. In addition, when the original cable lines have already been laid out, the cables can be expanded and optimized by adding extended bridges 6 without changing the original cable layout, thereby improving the flexibility and scalability of cable management.

[0033] In practice, the installation process of the prefabricated hoisting cable tray is simple and quick. First, the installation location and number of the base cable tray 5 are determined based on the actual site conditions. Then, the appropriate number of extension cable trays 6 and reinforced underlayment 7 are selected based on the number and classification of cables to be routed. The fast-locking mechanism, with its fixed buckle 10 and movable buckle 16, allows for easy and rapid installation and removal of the cable tray, significantly improving construction efficiency.

[0034] Furthermore, the design of the prefabricated overhead cable tray fully considers cable protection and maintenance. The multi-compartment design within the tray effectively prevents cables from crossing and entanglement, while also facilitating cable sorting and identification. The curved structure 14 and cushioning material pads 12 of the reinforced underlay 7 effectively reduce mechanical stress and vibration on the cables, extending their service life. The prefabricated overhead cable tray also excels in maintenance and overhaul.

[0035] In summary, the modular design of this prefabricated hoisting cable tray not only improves the ease of installation, disassembly, and maintenance, but also significantly enhances its structural strength and stability through the design of reinforced base lining and vertical partitions. Furthermore, the quick-locking mechanism and keyhole design further enhance the safety and reliability of the cable tray system, meeting the requirements for high-load capacity and convenient installation in large factories, high-rise buildings, and other environments.
