Technical Field

[0001] This utility model relates to the field of cable laying technology, and more specifically, to a cable laying device for power engineering that is easy to load and unload. Background Technology

[0002] Cable trays, also known as cable management trays, are an indispensable component of cabling systems. They are primarily used to support, protect, and manage cables and wires in an orderly manner. Cable trays play a vital role in various engineering projects, ensuring the safety, aesthetics, and efficiency of cabling. Made of metal, plastic, or other durable materials, cable trays can accommodate different cable types and specifications, such as power cables, communication cables, and network cables. Their main functions are to support and protect cables, and to organize and manage them.

Due to gravity, the two ends of the cable will be pressed against the two ends of the cable installation position, causing bending. Long-term use will affect the stability of the overall laying support. Therefore, we have made improvements to this and proposed a cable laying device for power engineering that is easy to load and unload. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] like Figures 1-6 As shown, this embodiment proposes a cable laying device for power engineering that is easy to load and unload, including a laying bracket 1 and a positioning frame 2. The positioning frame 2 is movably connected to the laying bracket 1. Multiple sets of laying pipe grooves 3 are arranged at equal intervals on the upper end of the laying bracket 1. Each set of laying pipe grooves 3 has a set of support components and a set of embedding grooves at the front and rear ends of the opening. The support components are used to distribute the pressure at both ends of the laying pipe grooves 3 after the cable is laid. The support components include two sets of support frames 4 located at the front and rear ends of the laying pipe grooves 3. Each set of support frames 4 has a linkage rod 5, a sliding rod 6, a sliding cylinder 7 and a rotating ring 9 arranged in sequence at the lower end. A rotating shaft 10 is provided in the center of the rotating ring 9. A rotating rod 11 is provided at the outer end of the rotating shaft 10. A positioning shaft 12 and a linkage gear 13 are provided at the lower end of the rotating rod 11. The two sets of linkage gears 13 are respectively meshed with a lower gear and an upper gear. A belt 14 is fixed at the outer end of the lower gear and the upper gear. A receiving shaft 22 is movably connected to one end of the belt 14. A drum 20 and a linkage spring 21 are wrapped around both ends of the receiving shaft 22.

[0032] The lower end of the support frame 4 is fixedly connected to the linkage rod 5, and the lower end of the linkage rod 5 is fixedly connected to the slide rod 6. The slide rod 6 is wrapped inside the slide cylinder 7, and a positioning spring 8 is wrapped between the slide rod 6 and the slide cylinder 7. The rotating ring 9 is fixed to the lower end of the slide cylinder 7, and the rotating ring 9 is wrapped around the outer end of the rotating shaft 10. The upper end of the rotating rod 11 is fixedly connected to the rotating shaft 10, and the lower end of the rotating rod 11 is fixedly connected to the positioning shaft 12.

[0033] The linkage gear 13 is fixed to the lower end of the rotating rod 11. One set of linkage gears 13 is meshed with the lower gear 15, and the other set of linkage gears 13 is meshed with the upper gear 16. One end of the belt 14 is wrapped around the outer end of the storage shaft 22, and the other end of the belt 14 passes through the outer end of the laying bracket 1. The belt 14 is first fixedly connected to the lower gear, and then fixedly connected to the upper gear. The drum 20 is embedded in the inner end of the laying bracket 1. One end of the linkage spring 21 is fixed inside the laying bracket 1, and the other end of the linkage spring 21 is fixed on the storage shaft 22. The outer end of the belt 14 is through a positioning ring 17. The outer end of the laying bracket 1 is provided with a threaded cylinder 19, and the inner end of the threaded cylinder 19 is provided with a positioning screw 18.

[0034] The corresponding cable is passed through multiple sets of laying pipe trenches 3 arranged at equal intervals within the laying support 1. Each set of laying pipe trenches 3 has a set of support components and a set of embedding grooves at the front and rear ends of the opening, which stabilizes the position of the cable by arrangement.

[0035] Pull the corresponding belt 14 under the corresponding installation duct 3. One end of the belt 14 is wrapped around the outer end of the storage shaft 22, and the other end passes through the laying bracket 1. After being stretched outward, the positioning ring 17 at the outer end of the belt 14 and the threaded cylinder 19 at the outer end of the laying bracket 1 pass through each other. The inner end of the threaded cylinder 19 is provided with a positioning screw 18. The positioning ring 17 and the threaded cylinder 19 are movably connected by the positioning screw 18 to ensure that the stretching of the belt 14 remains stable.

[0036] In addition, during the stretching process of belt 14, two sets of linkage gears 13 embedded in the groove are fixed to the lower end of rotating rod 11 and rotate in opposite directions through their respective meshing lower and upper gears. One set of linkage gears 13 meshes with the lower gear and the other set meshes with the upper gear.

[0037] The rotating rods 11 connected to the outer ends of the two sets of linkage gears 13 rotate around the positioning shaft 12. The upper end of the rotating rod 11 is fixed to the rotating shaft 10, and the lower end is fixed to the positioning shaft 12, so that the included angle between the two sets of rotating rods 11 is reduced.

[0038] The rotating shaft 10 located at the upper end of the rotating rod 11 is connected to the rotating ring 9. The rotating ring 9 is fixed at the lower end of the slide cylinder 7 and wraps around the rotating shaft 10. The slide cylinder 7 is wrapped with the slide rod 6. There is a positioning spring 8 between the two. The lower end of the slide rod 6 is fixed to the linkage rod 5. One end of the linkage spring 21 is fixed to the laying bracket 1, and the other end is fixed to the storage shaft 22. The slide cylinder 7 and the slide rod 6 at the upper end of the rotating ring 9 are subjected to the springing of the linkage spring 21, which generates relative movement, thereby reducing the usable length between the slide cylinder 7 and the slide rod 6.

[0039] The lower end of the support 4 is fixed to the linkage rod 5. The support 4 corresponding to the linkage rod 5 slides inward along the embedded groove and then wraps around the outside of the corresponding cable. By dispersing the pressure at both ends of the cable laying trough 3 through the support component, the cable at both ends of the cable laying trough 3 is expanded and the cable is stabilized, avoiding the cable bending on the laying bracket 1 due to gravity, which would affect the laying of other sections.

[0040] The positioning frame 2 is movably connected to the laying bracket 1. Each laying bracket 1 and positioning frame 2 is fixed to the wall, cement pole, or other parts by expansion bolts, etc., to ensure the stable installation of the laying bracket 1.

[0041] The laying pipe groove 3 at the upper end of the laying bracket 1, the support components and linkage structure including the linkage rod 5, the slide rod 6, the slide cylinder 7, the rotating ring 9, the gear set, etc., together ensure the uniformity of load-bearing and the anti-bending function during cable laying.

[0042] In use: The corresponding cable is laid through the laying support 1 and the laying pipe groove 3 is arranged stably. The corresponding belt 14 is pulled under the corresponding laying pipe groove 3. After being stretched outward, the positioning ring 17 on the belt 14 and the threaded cylinder 19 at the outer end of the laying support 1 are mutually connected. The positioning ring 17 and the threaded cylinder 19 are movably connected by the positioning screw 18 to ensure that the tension of the belt 14 remains stable.

[0043] Furthermore, during the stretching process of belt 14, the two sets of linkage gears 13 embedded in the groove rotate towards each other through their respective meshing lower and upper gears. The rotating rods 11 connected to the outer ends of the two sets of linkage gears 13 rotate around the positioning shaft 12. The included angle between the two sets of rotating rods 11 decreases. The rotating shaft 10 located at the upper end of the rotating rod 11 is connected to the rotating ring 9. The slide cylinder 7 and the slide rod 6 at the upper end of the rotating ring 9 are subjected to the spring movement of the linkage spring 21, which reduces the usable length between the slide cylinder 7 and the slide rod 6. The support 4 corresponding to the linkage rod 5 slides inward along the embedded groove and then wraps around the corresponding cable outside, expanding the cable at both ends of the cable laying duct 3 to stabilize the force and prevent the cable from bending due to gravity on the laying support 1, which would affect the laying of other sections.

[0044] Each laying bracket 1 and positioning bracket 2 is fixed to the wall, cement pole, or other parts by expansion bolts, etc., to ensure the stable installation of the laying bracket 1.

[0045] Furthermore, it should be understood that in this application, all rotating, sliding, meshing, belt 14 driven and other moving parts are well lubricated and not prone to slippage or wear, and each of them is provided with a corresponding protective shell. However, in the accompanying drawings of this application, the connection state of each moving part is not shown. It should also be understood that each part in this application is made of metal, plastic or rubber material with adaptable strength in the relevant field to ensure that its structural rigidity meets the actual requirements.

[0046] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above.
