Description

Technical Field

[0001] The utility model relates to the technical field of cable bridges, in particular to a trough-type cable bridge. Background Art

[0002] Cable tray is the full name of a rigid structural system composed of straight sections, bends, components, supports, hangers, etc. of trays or ladders with close support for cables. Cable trays are generally suitable for large enterprises, large-scale power transformation, cable laying, large bridges, subway cable laying and offshore drilling. Cable trays are usually set at the bottom of the ceiling of the building in a suspended manner. Cable trays are widely used in petrochemical, metallurgy, electric power, school communications, high-rise buildings and other fields. They have beautiful appearance, strong corrosion resistance, wide versatility, flexible and convenient installation, and a full range of varieties. With the increasing electricity consumption in various fields, there are more and more cable lines, and modular cable trays came into being.

[0003] Cable trays are essential components in power systems, data centers, or any location requiring extensive cable management. They support, protect, and organize cables to ensure safe, reliable operation and convenient maintenance. While traditional cable trays meet these requirements to a certain extent, they have limitations in terms of installation, maintenance, and management of different cable types. For example, traditional cable trays often require on-site fabrication and adjustment to accommodate specific cable types, which is time-consuming and increases installation costs. Furthermore, if expansion or renovation is required, traditional cable tray systems lack flexibility, often requiring the replacement of entire sections or complex modifications. To address these issues, a trough-type cable tray has been proposed. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a trough-type cable tray, which aims to improve the problem in the prior art that the cable tray cannot directly fix different types of cables and cannot be installed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The top of the partition board is fixedly connected to the limiting plate of the present invention, and the limiting plate is fixedly provided with a pinion plate, and the limiting plate is fixedly provided with a pinion plate.

[0007] Furthermore, the basic components of the trough-type cable tray and their connection methods are described. Through the engagement of the gear and the rack plate, the sliding plate can drive the partition to move along the guide groove, thereby adjusting the spacing between the partitions to adapt to the installation of different types of cables.

[0008] As a further description of the above technical solution: the splicing assembly includes a tooth mortise and tenon piece, the bottom end of the tooth mortise and tenon piece is fixedly connected to the top end of the right-angle cable tray and the left side of the right-angle cable tray, the middle part of the tooth mortise and tenon piece is provided with a through groove, the right side of the external bridge rod is provided with a tooth notch, and the top side of the right end of the external bridge rod is provided with a hole groove;

[0009] Furthermore, the structure of the splicing assembly is mainly introduced. A stable connection between the bridge frames is achieved through the engagement of the toothed mortise and tenon parts with the toothed notches on the external bridge frame rods, and the threaded connection of the bolts with the through slots and hole slots.

[0010] As a further description of the above technical solution: the rear side of the gear is slidably connected to the front and rear sides of the right-angle cable tray, and the outer teeth of the gear are meshed with the top teeth of the rack plate;

[0011] Furthermore, the meshing connection between the gear and the rack plate enables smooth movement of the sliding plate and the limit plate. This illustrates that the meshing of the gear and the rack plate is the core of the entire adjustment mechanism. By manually pulling the sliding plate, the gear rolls on the rack plate, driving the limit plate and the partition plate to move, completing the classification and installation of the cables.

[0012] As a further description of the above technical solution: the adjacent sides of the two limit plates are slidably connected to the distant sides of the two partitions, and the outer bottom end of the clamping member is engaged with the outer side of the toothed plate;

[0013] Furthermore, the partitions are secured in place by the sliding connection between the limit plate and the partitions, and the engagement of the clamps with the toothed disc. The implementation of a self-locking mechanism is described, whereby the clamps engage the toothed disc to prevent the partitions from moving freely once adjusted to the proper position, thus ensuring the stability of the cable arrangement.

[0014] As a further description of the above technical solution: the side of the gear away from the right-angle cable tray is rotatably connected to the side of the limit plate close to the right-angle cable tray, and the side of the clamp close to the right-angle cable tray is slidably connected to the side of the limit plate away from the right-angle cable tray;

[0015] Furthermore, the smooth rotation and self-locking function of the gear are achieved through the rotational connection between the gear and the limit plate, and the sliding connection between the clamp and the limit plate. This emphasizes the importance of the rotational connection between the gear and the limit plate to the entire adjustment mechanism, while the sliding connection between the clamp and the limit plate is also the key to achieving the self-locking function.

[0016] As a further description of the above technical solution: the top end of the partition is slidably connected to the bottom end of the sliding plate;

[0017] Furthermore, the spacing between the partitions can be adjusted by sliding the partitions and the sliding plates. This paper describes how the spacing between the partitions can be adjusted by sliding the partitions and the sliding plates, which is the basis for adapting to different cable installation requirements.

[0018] As a further description of the above technical solution: the left outer portion of the tooth mortise and tenon member at the left end is engaged with the inner wall of the tooth gap;

[0019] Furthermore, the initial fixation of the splicing assembly is achieved through the engagement of the toothed mortise and tenon parts with the toothed notches. This explains how the splicing assembly achieves a quick and stable connection through the engagement of the toothed mortise and tenon parts with the toothed notches, laying the foundation for the final fixation of the subsequent bolts.

[0020] As a further description of the above technical solution: the external thread of the bolt is connected to the inner wall of the through groove, and the external thread of the bolt is connected to the inner wall of the hole groove.

[0021] Furthermore, the final fixation of the splicing assembly is achieved through the threaded connection between the bolts and the through slots and hole slots. Finally, the role of the bolts in the splicing process is clarified. Through the threaded connection with the through slots and hole slots, the stability of the splicing assembly is ensured, and the rapid installation and fixation between the bridges is completed.

[0022] The utility model has the following beneficial effects:

[0023] 1. In the present invention, by sliding the sliding plate, the guide groove of the sliding plate limits the sliding area of the limit column of the partition, so that the sliding of the sliding plate can drive the spacing of the partitions fixed by the limit column to change, thereby helping to install different types of cables, making the cable wiring more orderly, facilitating the inspection and replacement of cables, and improving maintenance efficiency and safety.

[0024] 2. In the present invention, the tooth notches of the external bridge rod are aligned with the tooth angles of the tooth mortise and tenon parts that fix the right-angle cable bridge, and the two are spliced and fixed. The bolts are then fixed in the hole grooves of the external bridge rod and the through grooves of the tooth mortise and tenon parts, thereby achieving a quick fixed connection between the external bridge rod and the right-angle cable bridge. The cable bridge can be pre-manufactured in the factory and directly delivered to the site, reducing the need for on-site processing and simplifying the installation process.

[0036] refer to Figure 4 , two positioning blocks 9 are fixedly connected to the front and back sides of the limit plate 5, and a spring sheet 10 is fixedly connected to the middle of the adjacent side of the two positioning blocks 9. The bottom end of the spring sheet 10 is fixedly connected to a clamp 11. The strong spring sheet 10 connects the positioning block 9 and the clamp 11. The side of the clamp 11 close to the right-angle cable tray 1 is slidably connected to the side of the limit plate 5 away from the right-angle cable tray 1. The outside of the bottom end of the clamp 11 is engaged with the outside of the toothed disk 7. The inner bottom end of the right-angle cable tray 1 is slidably connected with three partitions 12. The positioning block 9 uses elastic potential energy to pull the clamp 11 to engage with the external groove of the toothed disk 7 to achieve self-locking, ensuring that the partition 12 can remain stable after being adjusted to the appropriate position.

[0037] The top end of the partition 12 is slidably connected to the bottom end of the sliding plate 3, and the adjacent sides of the two limit plates 5 are slidably connected to the distant sides of the two partitions 12. The middle part of the top end of the partition 12 is fixedly connected to the limiting column 13. The partition 12 is connected to the guide groove 4 of the sliding plate 3 through the limiting column 13. The spacing can be adjusted along the guide groove 4 to distinguish different types of cables.

[0039] Working principle: When different types of cables need to be installed inside the cable tray, in order to help install and classify the cables, the sliding plate 3 and the limit plate 5 can be pulled to slide to the external position of the bottom end of the right-angle cable tray 1, and the gear 8 fixed by the rotating shaft 6 in the middle of the limit plate 5 can be rotated to engage with the rack plate 2 fixed on the front and rear sides of the top of the right-angle cable tray 1, so that the guide groove 4 of the sliding plate 3 can slide stably, and the limit column 13 fixed to the partition 12 can be driven to slide by the inclination of the left and right grooves of the guide groove 4 and the length of the middle groove. After the limit column 13 slides, the partition 12 will automatically adjust the distance between them along the groove path of the guide groove 4, so as to facilitate the distinction between different types of cables installed inside the right-angle cable tray 1, and help the cables to be straightened out for installation.

[0040] When the gear 8 engages with the teeth of the rack plate 2, the gear 8 fixes the toothed plate 7 through the rotating shaft 6 and rotates up and down through the external protruding toothed extrusion clamp 11. At this time, since the spring sheet 10 has a strong elastic force, the spring sheet 10 will pull the clamp 11 to engage with the external groove of the toothed plate 7 through its own elastic potential energy, and cooperate with the force of the teeth of the rack plate 2 engaging with the external teeth of the gear 8, so as to realize self-locking after the sliding plate 3 and the limit plate 5 are moved to the appropriate position.

[0041] When the right-angle cable tray 1 and other bridges need to be fixed, the tooth gap 17 on the left side of the external bridge rod 16 can be aligned with the tooth mortise and tenon 14 of the right-angle cable tray 1, and then squeezed and clamped. This allows the toothed outer part of the tooth mortise and tenon 14 and the tooth gap 17 to engage with each other, ensuring the initial stable fixation of the right-angle cable tray 1 and the external bridge rod 16, making it easier for the installer to position and install. After the external bridge rod 16 is initially fixed, the bolt 19 is aligned with the through slot 15 of the tooth mortise and tenon 14 and threaded into the hole slot 18 of the tooth mortise and tenon 14 and the external bridge rod 16, thereby achieving rapid installation and fixation of the cable tray.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
