[0002] In power transmission and transformation projects, cable trays serve as important facilities for carrying and protecting cables. They enable the orderly arrangement of cables, effectively utilize space, and make the layout of power transmission and transformation sites more neat and aesthetically pleasing. The rationality of their structure and the ease of splicing have a significant impact on improving project construction efficiency, controlling costs, and facilitating subsequent maintenance.

[0003] The splicing methods of some existing power transmission and transformation cable trays are quite complex, requiring the use of bolts and nuts for assembly. Tightening the nuts requires the use of tools such as wrenches, which slows down the entire installation process, consumes time, and requires manpower, increasing the time and labor costs of construction. Therefore, it is necessary to design a quick-assembly power transmission and transformation cable tray structure to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a quick-connection power transmission and transformation cable tray structure to solve the problems mentioned in the background art.

[0005] The technical solution adopted by this application to solve its technical problem is: a quick-connection power transmission and transformation cable tray structure, including a main cable tray and an auxiliary cable tray, wherein the auxiliary cable tray is installed at the front end of the main cable tray, and further includes an assembly frame and a reinforcing frame. The assembly frame is installed at the rear ends of both sides of the main cable tray and the auxiliary cable tray, and the assembly frame is provided with an assembly groove. A reinforcing plate is hingedly connected in the assembly groove. The reinforcing frame is installed at the front ends of both sides of the main cable tray and the auxiliary cable tray, and the reinforcing frame is provided with a reinforcing groove. The reinforcing plate can be hingedly rotated from the assembly groove to the reinforcing groove, which is suitable for reinforcing the connection part of the main cable tray and the auxiliary cable tray.

[0006] The rear end of the reinforcing frame is provided with an installation groove that communicates with the reinforcing groove. Multiple springs are fixed in the installation groove. A limiting plate is fixed to the front end of the spring. The limiting plate slides along the installation groove. The rear end of the reinforcing plate is provided with a limiting groove. The limiting plate is located in the limiting groove.

[0007] Furthermore, the spring causes the limiting plate to maintain its tendency to move toward the reinforcing plate and engages it within the limiting groove.

[0008] Furthermore, the reinforcing frame is provided with a movable groove that communicates with the mounting groove, and a push plate is fixed on one side of the limiting plate, the push plate sliding within the movable groove.

[0009] Furthermore, the front end of the reinforcing frame is fixed with two locking pins, and the rear end of the assembly frame is provided with a locking groove, in which the locking pins are engaged.

[0010] Furthermore, multiple positioning rods are fixed to the rear ends of the main cable tray and the auxiliary cable tray, and multiple positioning sleeves are fixed to the front ends of the main cable tray and the auxiliary cable tray. The positioning rods at the connection between the main cable tray and the auxiliary cable tray are inserted into the positioning sleeves at the connection between the main cable tray and the auxiliary cable tray.

[0011] Furthermore, two sets of positioning plates are fixed to the rear ends of the bottom of the main cable tray and the auxiliary cable tray, and two sets of positioning boxes are fixed to the front ends of the bottom of the main cable tray and the auxiliary cable tray.

[0015] By adopting the above technical solution, the problems of complex splicing methods, reliance on bolts and nuts for fixing, slow installation process, and high time and manpower consumption of traditional equipment have been solved.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: by setting up an assembly frame, a reinforcing frame, a reinforcing plate, and a spring, the reinforcing plate rotates from the assembly slot of the assembly frame to the reinforcing slot of the reinforcing frame. The reinforcing slot restricts the lateral displacement of the reinforcing plate, achieving initial reinforcement. Subsequently, the spring pushes the limiting plate to lock in the limiting slot of the reinforcing plate, restricting the rotation and longitudinal displacement of the reinforcing plate, so that the reinforcing plate is stably kept in the reinforced position, continuously providing stable reinforcement for the connection parts of the cable tray, ensuring that the cable tray is firmly connected during long-term use, thereby simplifying the installation steps of the main cable tray and auxiliary cable tray and reducing its installation time.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-7 This invention provides a technical solution: a quick-connection power transmission and transformation cable tray structure, including a main cable tray 1 and an auxiliary cable tray 2. The main cable tray 1 and the auxiliary cable tray 2 are made of aluminum alloy, which has good load-bearing capacity and can stably support cables. The auxiliary cable tray 2 is installed at the front end of the main cable tray 1, and the two are compatible in size. Multiple partitions 7 are fixed inside the main cable tray 1 and the auxiliary cable tray 2. The partitions 7 can separate different cables. Multiple ventilation holes 8 are provided on both the main cable tray 1 and the auxiliary cable tray 2. The ventilation holes 8 are evenly distributed on the surface of the cable tray and are circular in shape. The ventilation holes 8 can allow air to circulate naturally inside the cable tray, remove the heat generated during the operation of the cables, and reduce the internal temperature of the main cable tray 1 and the auxiliary cable tray 2. Dust covers 9 are slidably connected to the main cable tray 1 and the auxiliary cable tray 2. The dust covers 9 are made of high-strength plastic and can effectively block dust and debris. The dust covers 9 have sliding grooves on both sides, which cooperate with the sliding rails on the main cable tray 1 and the auxiliary cable tray 2 to ensure smooth sliding.

[0027] Multiple positioning rods 3 are fixed to the rear ends of the main cable tray 1 and the auxiliary cable tray 2. The positioning rods 3 are welded to the main cable tray 1 and the auxiliary cable tray 2 to ensure a firm connection. The front end of the positioning rod 3 is tapered to facilitate the insertion of the positioning sleeve 4. Multiple positioning sleeves 4 are fixed to the front ends of the main cable tray 1 and the auxiliary cable tray 2. The inner diameter of the positioning sleeve 4 matches the outer diameter of the positioning rod 3. The positioning rod 3 at the connection between the main cable tray 1 and the auxiliary cable tray 2 is inserted into the positioning sleeve 4 to position the main cable tray 1 and the auxiliary cable tray 2 longitudinally, ensuring that the main cable tray 1 and the auxiliary cable tray 2 are positioned correctly. For accurate alignment along the length, two sets of positioning plates 5 are fixed at the rear ends of the bottom of the main cable tray 1 and the auxiliary cable tray 2. The positioning plates 5 are made of stainless steel, which is corrosion-resistant and has high strength. Two sets of positioning boxes 6 are fixed at the front ends of the bottom of the main cable tray 1 and the auxiliary cable tray 2. The size of the positioning boxes 6 is adapted to the positioning plates 5. The positioning plates 5 at the connection between the main cable tray 1 and the auxiliary cable tray 2 are inserted into the positioning boxes 6 to position the main cable tray 1 and the auxiliary cable tray 2 from the bottom, effectively limiting the vertical displacement of the main cable tray 1 and the auxiliary cable tray 2 and enhancing the stability of the splicing.

[0028] It also includes an assembly frame 10 and a reinforcing frame 11. The assembly frame 10 is welded and fixed to the rear ends of both sides of the main cable tray 1 and the auxiliary cable tray 2. The assembly frame 10 is made of high-strength aluminum alloy, which is lightweight and high-strength. Its shape fits the sides of the main cable tray 1 and the auxiliary cable tray 2. The assembly frame 10 is provided with an assembly groove 12, and a reinforcing plate 13 is hinged in the assembly groove 12. The hinge is made of stainless steel to ensure that the reinforcing plate 13 can rotate flexibly and is durable. The reinforcing frame 11 is installed on the main cable tray 1 and the auxiliary cable tray 2. The front ends of both sides of the auxiliary cable tray 2 are also made of high-strength aluminum alloy. The reinforcing frame 11 is provided with a reinforcing groove 14. The size of the reinforcing groove 14 matches the reinforcing plate 13. The reinforcing plate 13 can be hinged and rotated from the assembly groove 12 into the reinforcing groove 14. The reinforcing groove 14 restricts the lateral displacement range of the reinforcing plate 13, thereby reinforcing the connection between the main cable tray 1 and the auxiliary cable tray 2. During the rotation, the reinforcing plate 13 and the reinforcing groove 14 fit tightly together, effectively enhancing the stability of the connection.

[0029] The rear end of the reinforcing frame 11 is provided with an installation groove 16 that communicates with the reinforcing groove 14. The interior of the installation groove 16 is smooth and burr-free, ensuring smooth sliding of the limiting plate 19. Multiple springs 18 are fixed in the installation groove 16. The springs 18 are made of high-elasticity alloy material, which has good elasticity and fatigue resistance. The front end of the springs 18 is fixed with the limiting plate 19, which is made of wear-resistant engineering plastic, lightweight and with moderate friction. The limiting plate 19 slides along the installation groove 16. The rear end of the reinforcing plate 13 is provided with a limiting groove 15. The limiting plate 19 is located in the limiting groove 15. The springs 18 keep the limiting plate 19 moving towards the reinforcing plate 13 and engage it in the limiting groove 15, restricting the rotation and longitudinal displacement of the reinforcing plate 13, so that the reinforcing plate 13 is stably maintained in the current reinforcing position, and continuously applying a stable reinforcing effect to the connection between the main cable tray 1 and the auxiliary cable tray 2.

[0030] The reinforcing frame 11 is provided with a movable groove 17 that communicates with the mounting groove 16. The width of the movable groove 17 is slightly larger than the height of the push plate 20, ensuring that the push plate 20 can slide freely in it. The push plate 20 is fixed on one side of the limiting plate 19. The push plate 20 is made of metal and its surface is treated with anti-rust. The push plate 20 slides in the movable groove 17, which makes it convenient to push the push plate 20 to disengage the limiting plate 19 from the limiting groove 15 when the cable tray needs to be disassembled, thus facilitating operation.

[0031] The front end of the reinforcing frame 11 is fixed with two locking pins 21. The locking pins 21 are made of high-strength carbon steel, which is hard and not easily deformed. The rear end of the assembly frame 10 is provided with a slot 22. The locking pins 21 are engaged in the slot 22, which plays a role in quick positioning and initial fixation in the early stage of splicing, reducing the adjustment time during splicing and improving the installation efficiency.

[0032] Working principle: In the actual application scenario of power transmission and transformation engineering, the cable is laid inside the main cable tray 1 and the auxiliary cable tray 2;

[0033] During the splicing of the main cable tray 1 and the auxiliary cable tray 2, the positioning rod 3 is inserted into the positioning sleeve 4 to position the main cable tray 1 and the auxiliary cable tray 2 in the longitudinal dimension, ensuring that the main cable tray 1 and the auxiliary cable tray 2 are aligned in the length direction. The positioning plate 5 and the positioning box 6 are positioned from the bottom of the main cable tray 1 and the auxiliary cable tray 2. The positioning plate 5 is inserted into the positioning box 6, which effectively restricts the vertical displacement of the main cable tray 1 and the auxiliary cable tray 2. The combination of the locking pin 21 and the locking groove 22 plays the role of quick positioning and initial fixation on the side of the main cable tray 1 and the auxiliary cable tray 2. The locking pin 21 is inserted into the locking groove 22, which allows the main cable tray 1 and the auxiliary cable tray 2 to be quickly aligned in the early stage of splicing, shortening the adjustment time and improving the splicing efficiency.

[0034] After the main cable tray 1 and auxiliary cable tray 2 are spliced, in order to further strengthen the stability of their connection, the push plate 20 should be manually pushed with the right hand to move horizontally within the movable groove 17. The horizontal movement of the push plate 20 causes the limiting plate 19 to move within the mounting groove 16, thereby making room for the reinforcing plate 13 to enter the reinforcing groove 14. At this time, the reinforcing plate 13 is rotated from the mounting groove 12 of the assembly frame 10 to the reinforcing groove 14 of the reinforcing frame 11 with the left hand. The reinforcing groove 14 restricts the lateral displacement of the reinforcing plate 13. Within the range, the connection between the main cable tray 1 and the auxiliary cable tray 2 is reinforced. When the reinforcing plate 13 is fully inserted into the reinforcing groove 14, the right hand releases the push plate 20, and the spring 18 applies a pushing force to the limiting plate 19, causing the limiting plate 19 to be firmly locked in the limiting groove 15 of the reinforcing plate 13, further restricting the rotation and longitudinal displacement of the reinforcing plate 13, so that the reinforcing plate 13 is stably maintained in the current reinforcing position, and continuously applying a stable reinforcing effect to the connection between the main cable tray 1 and the auxiliary cable tray 2.

[0035] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
