Description

Technical Field

[0001] This invention relates to the field of cable tray technology, and more particularly to a cable tray. Background Technology

[0002] Traditional cable trays are primarily used to support and protect cable lines, ensuring the orderly arrangement and safe operation of cables. However, with the development of industrial automation and intelligence, the requirements for cable trays are no longer limited to basic support and protection functions. More intelligent and automated solutions are needed to improve the efficiency and safety of cable management and maintenance. Furthermore, traditional cable trays lack automated fixing and auxiliary tools during cable installation and maintenance, leading to cumbersome installation processes, heavy maintenance workloads, and difficulty in adapting to rapidly changing industrial demands. Additionally, existing cable trays lack auxiliary tools during cable installation and maintenance. When cables pass through corners of the cable tray, the end of the cable at the corner is bent, while most corners of existing cable trays are right angles. This causes the cable to come into direct contact with the right angle. Over time, or when the cable experiences vibration during use, friction occurs between the cable and the right angle of the cable tray corner, causing wear at the bend and affecting the cable's lifespan and safety.

[0003] When existing cables are laid flat, when the cables pass through the corners of the cable tray, the laid cables will move closer to the corners of the cable tray, causing the cables at the corners to be squeezed together and stacked. At the same time, the right angle at the corners of the cable trays will also cause wear and tear on the cables. In addition to making it inconvenient to manage the cables, it will also cause the cables to get tangled and reduce their service life. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that cables may stack or squeeze each other when passing through the corners of cable trays, and to propose a cable tray.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cable tray includes a tray body, a cover plate at the top of the tray body, and a distribution mechanism for distributing cables inside the tray body.

[0007] The distribution mechanism includes a slide groove opened at the corner of the cable tray body, a movable block slidably connected inside the slide groove, and an arc-shaped component hinged to the movable block and the corner of the cable tray body.

[0008] The cables are distributed via a rotating ring mounted on an arc-shaped component, preventing them from stacking or tangling when passing through the corners of the cable tray body.

[0009] It also includes a pusher assembly mounted on the cable tray body, which works with the moving block to control the curvature of the curved parts.

[0010] As a further description of the above technical solution:

[0011] The arc-shaped component is made of flexible material and is symmetrically hinged on both sides of the moving block. The arc-shaped component is located at two corners of the cable tray body.

[0012] As a further description of the above technical solution:

[0013] The rings are equidistantly installed inside the arc-shaped component, and the arc-shaped component has a groove larger than the rings for mounting.

[0014] As a further description of the above technical solution:

[0015] Both sides of the ring are set as arc-shaped surfaces, and a rubber pad is provided on the inner surface of the ring.

[0016] As a further description of the above technical solution:

[0017] The pushing component includes a threaded rod threaded onto one side of the cable tray body, a square plate rotatably connected to one side of the threaded rod, a spring fixedly installed between the square plate and the moving block, and an insert rod fixedly connected to one side of the moving block.

[0018] As a further description of the above technical solution:

[0019] The insertion rods are symmetrically installed on the side of the movable block near the insertion rods, and the square plate has symmetrical holes on the side near the insertion rods, with the size of the holes being the same as that of the insertion rods.

[0020] As a further description of the above technical solution:

[0021] One end of the threaded rod passes through and extends to the outside of the cable tray body, and the size of the movable block is smaller than that of the square plate.

[0022] As a further description of the above technical solution:

[0023] The threaded rod extends to one end of the cable tray body in a rectangular shape, and the moving block and the arc-shaped component have the same height.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0025] 1. By symmetrically setting arc-shaped parts at the corners of the cable tray body, when the cable is laid flat to the corner of the cable tray body, the cable passes through the inside of the ring. The equally spaced rings can distribute the cable and prevent the cable from stacking or tangling at the corner. The rotating ring can rotate according to the degree of bending of the cable, reducing the degree of bending of the cable at the corner. At the same time, the arc-shaped surfaces on both sides of the ring can reduce the wear on the cable surface.

[0026] 2. At the same time, after the cable is laid inside the arc-shaped component, the bending point of the cable will always be in contact with the inner surface of the ring due to tension. The tension will also give the arc-shaped component a certain force, causing the arc-shaped component to push the moving block through the hinge point with the moving block, so that the moving block moves towards the square plate. At this time, the bending range of the arc-shaped component is reduced, which can reduce the bending range of the cable at the corner and increase the service life of the cable.

[0027] 3. When the moving block moves toward the square plate, the pins on both sides of the moving block will be inserted into the holes of the square plate. The tension brought by the arc-shaped parts allows the moving block to engage with the square plate. The ring can prevent the cable from swaying left and right. Attached Figure Description

[0039] 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.

[0040] like Figure 1 - Figure 8 As shown, the present invention provides a cable tray, including a tray body 10, with a cover plate 11 at the top of the tray body 10. The tray body 10 is a T-shaped cable tray as in the prior art. The tray body 10 and the cover plate 11 are fixed together by bolts. The tray body 10 mainly serves as a support for carrying cables, capable of bearing and distributing the weight of the cables, preventing excessive tension or bending of the cables, and ensuring the safe operation of the cables. At the same time, the tray body 10 can guide the cables along a specific path as needed. The tray body 10 is internally equipped with a distribution mechanism 20 for distributing cables. The distribution mechanism 20 is located at the corners of the tray body 10 to prevent cables from stacking or tangling at the corners of the tray body 10.

[0041] The distribution mechanism 20 includes a chute 21 opened at the corner of the cable tray body 10. A movable block 22 is slidably connected inside the chute 21. An arc-shaped component 23 is hinged to the movable block 22 and the corner of the cable tray body 10. By moving the movable block 22, the arc-shaped component 23 will also change the curvature of the bend through its own tension, so that the cable laid in the arc-shaped component 23 can reduce the bending amplitude at the corner of the cable tray body 10 and improve the service life of the cable.

[0042] The cables are distributed via a ring 24 mounted on an arc-shaped component 23, preventing the cables from stacking or tangling when passing through the corner of the cable tray body 10.

[0043] It also includes a push assembly 25 mounted on the cable tray body 10, which works with the moving block 22 to control the curvature of the arc-shaped component 23, thereby adapting to different cable installations.

[0044] In more detail, the arc-shaped component 23 is made of a flexible and elastic material, and is symmetrically hinged on both sides of the moving block 22. The arc-shaped component 23 is located at the two corners of the cable tray body 10. The distribution of cables is achieved through the arc-shaped component 23 and the internal ring 24, which can prevent the cables from being squeezed or knotted. It can also prevent the cables from contacting the right-angle surfaces at the corners of the cable tray body 10 and causing wear. When laying the cables, the bolts between the cable tray body 10 and the cover plate 11 are unscrewed, and then the cover plate 11 is removed. At this time, the cables are laid into the cable tray body 10. When encountering the corners of the cable tray body 10, the cables are passed through the internal ring 24 of the arc-shaped component 23. The ring 24 can distribute the cables and prevent the cables from being squeezed or stacked and knotted at the corners.

[0045] In more detail, the rings 24 are equidistantly installed inside the arc-shaped component 23. The arc-shaped component 23 has a groove inside for installing the rings 24, which is larger than the rings 24. The rotating rings 24 can rotate according to the degree of bending of the cable, reducing the degree of bending of the cable at the corner.

[0046] In more detail, both sides of the ring 24 are set as arc surfaces. The arc surfaces on both sides of the ring 24 can reduce the wear on the cable when the cable passes through the ring 24. The inner surface of the ring 24 is provided with a rubber pad. When the cable comes into contact with the inner surface of the ring 24, the rubber pad on the inner surface can also reduce the wear between the cable and the ring 24, further protecting the cable and improving the service life of the cable.

[0047] like Figure 7 - Figure 8 As shown, the pushing component 25 includes a threaded rod 251 threadedly mounted on one side of the cable tray body 10. A square plate 252 is rotatably connected to one side of the threaded rod 251. A spring 253 is fixedly installed between the square plate 252 and the moving block 22. A plug rod 254 is fixedly connected to one side of the moving block 22. By rotating the threaded rod 251 in both directions, the threaded rod 251 extends towards the inside or outside of the cable tray body 10. During the extension, the square plate 252 also moves. The square plate 252, in turn, moves the moving block 22 via the spring 253, allowing the curved parts 23 on both sides of the moving block 22 to adjust their curvature. In the initial state, there is a gap between the square plate 252 and the moving block 22 (e.g., ...). Figure 6As shown, the arc-shaped component 23 is given space to expand under tension. After the cable is laid inside the arc-shaped component 23, the bending point of the cable will always be in contact with the inner surface of one side of the ring 24 due to the tension. The tension also applies a certain force to the arc-shaped component 23, causing the arc-shaped component 23 to push the moving block 22 through the hinge point with the moving block 22, so that the moving block 22 moves towards the square plate 252. At this time, the bending amplitude of the arc-shaped component 23 is reduced, which can reduce the bending amplitude of the cable at the corner of the cable tray body 10 and increase the service life of the cable.

[0048] In more detail, the insertion rods 254 are symmetrically installed on the side of the movable block 22 near the insertion rods 254. The square plate 252 has symmetrical holes on the side near the insertion rods 254. The size of the holes is the same as that of the insertion rods 254. When the arc-shaped component 23 expands under the tension of the cable, the arc-shaped component 23 will drive the movable block 22 to move. The insertion rods 254 on both sides of the movable block 22 will be inserted into the holes of the square plate 252. The tension brought by the arc-shaped component 23 makes the movable block 22 able to engage with the square plate 252. The ring 24 can prevent the cable from swaying left and right.

[0049] In more detail, one end of the threaded rod 251 passes through and extends to the outside of the cable tray body 10. The size of the moving block 22 is smaller than that of the square plate 252. By rotating the threaded rod 251, the square plate 252 can be moved. At the same time, the moving block 22 is moved by the spring 253, thereby adjusting the curvature of the arc-shaped part 23.

[0050] In more detail, the threaded rod 251 extends to one end of the cable tray body 10 in a rectangular shape, and the moving block 22 and the arc-shaped part 23 have the same height.

[0051] Working principle: When laying cables, the bolts between the cable tray body 10 and the cover plate 11 are unscrewed, and then the cover plate 11 is removed. At this time, the cable is laid into the cable tray body 10. When encountering the corner of the cable tray body 10, the cable is passed through the ring 24 inside the arc-shaped part 23. The ring 24 can distribute the cable and prevent the cables from being squeezed or stacked and knotted at the corner.

[0052] Meanwhile, the cable inside the ring 24 is bent at this time. The tension of the cable will always overlap with the inner surface of one side of the ring 24. The tension of the cable will also cause the ring 24 to rotate, making the inner surface of the ring 24 fit more closely to the outer wall of the cable. The rubber pads on the arc-shaped surfaces on both sides of the ring 24 and the inner wall can reduce the wear between the cable and the ring 24 and improve the service life of the cable.

[0053] The tension of the cable will also act on the arc-shaped part 23, causing the end of the arc-shaped part 23 that is hinged to the moving block 22 to push the moving block 22, causing the moving block 22 to move towards the square plate 252. At this time, the curvature of the arc-shaped part 23 will be reduced, thereby reducing the curvature of the cable at the corner and preventing the cable from being damaged due to excessive bending.

[0054] When laying the cable tray body 10 at the corner, the threaded rod 251 is rotated in both directions to extend the threaded rod 251 toward the inside or outside of the cable tray body 10. While extending, the square plate 252 is also moved. The square plate 252 is then moved by the spring 253 to move the moving block 22, so that the arc-shaped parts 23 on both sides of the moving block 22 can adjust the bending arc. The degree of bending of the cable will be different depending on the material of the cable, so as to adapt to different cable installations.

[0055] The tension brought by the cable will cause the arc-shaped component 23 to drive the moving block 22. The plug rods 254 located on both sides of the moving block 22 will be inserted into the holes of the square plate 252. The tension brought by the arc-shaped component 23 will allow the moving block 22 to engage with the square plate 252. The ring 24 can prevent the cable from swaying left and right.

[0056] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
