Description

Technical Field

[0001] This application relates to the technical field of cable trays, and in particular to a cable tray structure suitable for cable reversing. Background Technology

[0002] Cable trays are a common tool used in cable laying, primarily for concentrating cables for easier installation and maintenance. With the increasing use of various electrified equipment and the growing complexity of engineering circuits, the installation of cable trays has become indispensable. A cable tray generally consists of a tray body and a cover plate, forming a conduit-like channel. The cover plate is mainly used to cover the cavity of the tray body, and this structure of cover plate and tray body facilitates cable laying.

[0003] During the installation of cable trays, multiple cable trays need to be laid according to the cable route, and the laid cable trays need to be connected and fixed. During the cable laying process, sometimes the cable needs to be turned and changed, and the cable needs to be transferred from the main line to the branch line. At the turning point of the main cable tray, a cable tray connection structure that can be turned needs to be set up, and the cable tray structure that can be turned needs to be connected and fixed to the main cable trays at both ends.

[0004] In the actual splicing and assembly process of existing cable trays, multiple sections of the tray need to be spliced ​​together end to end. Since the length of current cable trays is generally fixed as a whole section, the dimensions need to be determined in advance. However, in the actual laying process, the connection between the main cable tray and the reversing cable tray often requires cutting off the excess part or installing a new cable tray to make up for it due to various errors. Sometimes, the entire cable tray may even need to be adjusted. This requires re-customization or modification, which increases costs and delays the work. Utility Model Content

[0005] To eliminate connection errors between two adjacent cable tray sections, this application provides a cable tray structure suitable for cable flipping up and down.

[0006] This application provides a cable tray structure suitable for cable reversal, employing the following technical solution:

[0007] A cable tray structure suitable for cable flipping up and down includes main cable trays arranged in an array, corner cable trays connected between two adjacent main cable trays, and connecting devices disposed at the connection between the main cable trays and the corner cable trays. The connecting devices include multiple interconnected connecting plates. The length direction of the connecting plates is the same as the width direction of the main cable trays and the corner cable trays, and the multiple connecting plates are arranged along the length direction of the main cable trays. The connecting plates located at both ends of the multiple connecting plates are connected and fixed to the corresponding main cable trays and corner cable trays.

[0008] By adopting the above technical solution, when connecting the main cable tray and the corner cable tray, different numbers of connecting plates are selected according to the distance between them. Then, multiple connecting plates are spliced ​​and assembled. The two ends of the spliced ​​connecting plates are connected and fixed to the main cable tray and the corner cable tray respectively, thereby compensating for the errors between the main cable tray and the corner cable tray. The size of a single independent connecting plate can also be customized as needed to adapt to different installation environments. In the actual installation process, multiple connecting plates can be connected and fixed, avoiding the need to cut and fix the cable tray.

[0009] Optionally, the connecting device further includes a connector disposed between two adjacent connecting plates, the connector including a connecting block fixed to one of the connecting plates and a fixing bolt for fixing the connecting block to the other connecting plate.

[0010] By adopting the above technical solution, when splicing multiple connecting plates, the connecting blocks are set to connect with adjacent connecting plates, which facilitates the connection and fixation between the two. The connection between the connecting blocks and the connecting plates is fixed by fixing bolts, making it more convenient and faster to connect two adjacent connecting plates.

[0011] Optionally, two adjacent connecting plates can slide relative to each other.

[0012] By adopting the above technical solution, when installing multiple connecting plates, the horizontal distance between the two connecting plates can be adjusted by sliding the two connecting plates to accommodate the horizontal displacement error of the main cable tray and corner cable tray.

[0013] Optionally, a sliding groove is provided on the side of the connecting plate away from the connecting block, and the connecting blocks on the adjacent connecting plates slide in the sliding groove.

[0014] By adopting the above technical solution, when controlling the sliding of two adjacent connecting plates, the connecting block can slide in the sliding groove. The connecting block set in the sliding groove can play a guiding role, making the sliding process of the two connecting plates more stable.

[0015] Optionally, a limiting hole is formed on the surface of the connecting plate near the sliding groove. The length direction of the limiting hole is the same as the length direction of the sliding groove. The limiting hole communicates with the sliding groove, and the fixing bolt is slidably fitted in the limiting hole. The fixing bolt is threadedly connected to the connecting block.

[0016] By adopting the above technical solution, the limiting hole allows the fixing bolt to slide in the limiting hole. When adjusting the relative sliding of the two connecting plates, the fixing bolt can move with the connecting block, so that the fixing bolt slides along the length direction of the limiting hole. Furthermore, the fixing bolt being set in the limiting hole can prevent the connecting block from coming out of the sliding groove, making the sliding process more stable.

[0017] Optionally, a pair of protective plates are symmetrically arranged at both ends of the connecting plate, and the protective plates are perpendicular to the connecting plate.

[0018] By adopting the above technical solution, the two protective plates can be combined with the connecting plate to form a U-shaped structure similar to the main cable tray, preventing the laid cables from leaking out from both ends of the connecting plate and protecting the cables.

[0019] Optionally, a telescopic component is provided between the protective plate and the connecting plate. The telescopic component includes a fixed plate fixed to the end of the connecting plate and a sliding plate slidably fitted on the fixed plate. The protective plate is vertically fixed on the sliding plate.

[0020] By adopting the above technical solution, during the cable laying process, due to the different number of cables laid, the width of the main cable bridge and corner cable tray to be installed is also different. Workers can select cable trays and corner cable trays of different widths according to the number of cables to be installed in the main cable tray, thereby reducing the cost of installing cable trays. When faced with main cable trays and corner cable trays of different widths, workers can use telescopic components to adjust the distance between the protective plate and the sliding plate, so that the connection device can be applied to main cable trays and corner cable trays with different parameter specifications, thereby improving the applicability of the connection plate and the protective plate.

[0021] Optionally, a locking bolt is provided between the fixed plate and the sliding plate to secure both.

[0022] By adopting the above technical solution, after the fixed plate and the sliding plate have been adjusted, the sliding between them is restricted by the locking bolts, so as to prevent the protective plate from sliding toward the connecting plate during use.

[0023] Optionally, the connecting plate has a scale along its length on its surface, and the connecting block is aligned with the middle position of the scale.

[0024] By adopting the above technical solution, during the installation of multiple connecting plates, workers can adjust the horizontal distance between adjacent connecting plates based on the measured horizontal error data between the main cable tray and the corner cable tray. During the adjustment process, the data on the scale can be observed to allow the adjacent connecting plates to move horizontally by a fixed distance, avoiding large horizontal movements between adjacent connecting plates and preventing large-angle bends in the cables.

[0025] Optionally, a protective pad is laid on the protective plate on the same side of the multiple connecting plates. The protective pad is made of flexible material and insulating material.

[0026] By adopting the above technical solution, the protective pads set on the protective plate can prevent the cable surface from being scratched. At the same time, they can seal the gap between the two adjacent protective plates after they slide, so that the connecting plate and the two protective plates can form a closed U-shaped mechanism to prevent external impurities from falling onto the cable.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When faced with installation errors between main cable trays and corner cable trays, workers can choose different numbers of connecting plates to splice them, making installation more convenient and faster, avoiding the need to cut the cable trays on site, and improving installation efficiency;

[0029] 2. When the main cable tray and corner cable tray cannot be aligned during installation and there is a horizontal error, the workers can slide two adjacent connecting plates to make the adjacent connecting plates slide along the length of the connecting plates. In this way, multiple connecting plates can be used to make up for the horizontal error and finally connect and fix the main cable tray and corner cable tray. Attached Figure Description

Detailed Implementation

[0034] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0035] This application discloses a cable tray structure suitable for cable flipping up and down.

[0036] Reference Figure 1A cable tray structure suitable for cable reversal includes multiple main cable trays 1 with identical structures. The main cable trays 1 are installed along the cable laying direction. During installation, the ends of adjacent main cable trays 1 are connected and fixed. A T-shaped corner cable tray 2 is set at the position where the cable needs to be reversed. The cross-section of both the corner cable tray 2 and the main cable tray 1 is U-shaped. The corner cable tray 2 is set between two adjacent main cable trays 1. A connecting device 3 is set between the corner cable tray 2 and the adjacent main cable tray 1 to connect and fix the two. During installation, the workers install the main cable trays 1 in sequence and set the installation gap at the position where the cable needs to be reversed to facilitate the installation of the subsequent corner cable tray 2. When installing the corner cable tray 2, the corner cable tray 2 is set at the corresponding position, and the main cable tray 1 and the corner cable tray 2 are connected and fixed by the connecting device 3.

[0037] Reference Figure 1 and Figure 2 The connecting device 3 includes multiple connecting plates 31 arranged in a rectangular plate shape. The length direction of the connecting plates 31 is the same as the width direction of the main cable tray 1. The multiple connecting plates 31 are connected to each other through the sides. The connecting plates 31 located at both ends of the multiple connecting plates 31 are respectively connected and fixed to the corresponding main cable tray 1 and corner cable tray 2. When connecting and fixing the corner cable tray 2 and the main cable tray 1 that have been fixed in position through the connecting device 3, the staff first measures the error distance between the two, and then selects the corresponding number of connecting plates 31 according to the measured data. Then, the connecting plates 31 are spliced ​​between the corner cable tray 2 and the main cable tray 1, so that the main cable tray 1 and the corner cable tray 2 are connected and fixed.

[0038] A connector 32 is provided between the sides of two adjacent connecting plates 31. The connector 32 includes a rectangular connecting block 321 fixed on one of the connecting plates 31. The connecting block 321 is located at the middle position in the length direction of the connecting plate 31, and a fixing bolt 322 is provided on the connecting block 321. The connecting block 321 is connected and fixed to the other connecting plate 31 by the fixing bolt 322. When installing multiple connecting plates 31, they are quickly connected and fixed by the connecting block 321 and the fixing bolt 322. Different numbers of connecting plates 31 are connected and fixed according to actual needs. After the multiple connecting plates 31 are fixedly connected, the two ends of the plate-shaped structure formed by the multiple connecting plates 31 are placed between the corresponding main cable tray 1 and corner cable tray 2.

[0039] Reference Figure 1 and Figure 2Two adjacent connecting plates 31 can slide relative to each other along their length. A sliding groove 311 is provided on the side of a single connecting plate 31 away from the connecting block 321. The length direction of the sliding groove 311 is the same as the length direction of the connecting plate 31. When multiple connecting plates 31 are installed, the connecting block 321 can be inserted into the sliding groove 311 of another adjacent connecting plate 31. Through the connection block 321 and the sliding groove 311, two adjacent connecting plates 31 can slide relative to each other, thereby adjusting the horizontal distance between two adjacent connecting plates 31. When installing the main cable tray 1 and the corner cable tray 2, installation errors may occur, resulting in a horizontal error between the corner cable tray 2 and the main cable tray 1. This prevents the main cable tray 1 and the corner cable tray 2 from being accurately connected. Therefore, when installing multiple connecting plates 31, the horizontal distance between adjacent connecting plates 31 can be adjusted by sliding them relative to each other. The next connecting plate 31 to be installed can then be adjusted by sliding it, thereby compensating for the horizontal error between the main cable tray 1 and the corner cable tray 2 through multiple connecting plates 31.

[0040] A long, narrow limiting hole 312 is provided on the surface of the connecting plate 31 to be connected and fixed by the connecting block 321. The length direction of the limiting hole 312 is the same as the length direction of the sliding groove 311, and the limiting hole 312 communicates with the sliding groove 311. The fixing bolt 322 is threaded onto the connecting block 321 and is slidably disposed in the limiting hole 312, allowing the fixing bolt 322 to slide along the length direction of the limiting hole 312. After the connecting block 321 is inserted and fitted into the sliding groove 311, the fixing bolt 322 is then passed through the limiting hole 312 and tightened onto the connecting block 321. The limiting hole 312 not only prevents the connecting block 321 from detaching from the connecting plate 31, allowing adjacent connecting plates 31 to connect, but also serves as a guide during the sliding process of the connecting block 321 in the sliding groove 311, preventing slippage and misalignment between adjacent connecting plates 31.

[0041] Reference Figure 1 and Figure 3A pair of protective plates 33 are symmetrically arranged at both ends of each connecting plate 31. The protective plates 33 are perpendicular to the connecting plate 31, and the connecting plate 31 and the pair of protective plates 33 form a U-shaped structure, which can protect the blank areas at both ends of the connecting plate 31, thereby protecting the laid cables. A pair of telescopic members 34 are symmetrically arranged at both ends of the connecting plate 31. The telescopic members 34 are located at the connection position between the protective plates 33 and the connecting plate 31. The telescopic members 34 include a fixed plate 341 fixed to the end of the connecting plate 31. The length direction of the fixed plate 341 is the same as the length direction of the connecting plate 31. A sliding plate 342 is slidably fitted on the fixed plate 341. The sliding plate 342 is a sleeve structure, and the fixed plate 341 can be slidably inserted into the sliding plate 342. 2. The end away from the fixed plate 341 is fixed to the lower end of the protective plate 33, so that the protective plate 33 can extend away from the connecting plate 31 through the provided telescopic member 34. During the cable laying process, due to the different number of cables laid, the width direction of the main cable bridge and corner cable tray 2 to be installed is also different. The staff can select cable trays and corner cable trays 2 of different widths according to the number of cables to be installed in the main cable tray 1, so as to reduce the cost of installing cable trays. When facing main cable trays 1 and corner cable trays 2 of different widths, the staff can adjust the distance between the protective plate 33 and the sliding plate 342 through the telescopic member 34, so that the connecting device 3 can be applied to main cable trays 1 and corner cable trays 2 with different parameter specifications.

[0042] A locking bolt 343 is provided between the fixed plate 341 and the sliding plate 342 to fix them together. The locking bolt 343 passes through the fixed plate 341 and is threadedly connected to the fixed plate 341. The end of the locking bolt 343 can abut against the sliding plate 342. When it is necessary to adjust the distance between the fixed plate 341 and the sliding plate 342, first loosen the locking bolt 343, then slide to adjust the distance between the fixed plate 341 and the sliding plate 342. After the adjustment is completed, tighten the locking bolt 343 to fix the sliding plate 342 and the fixed plate 341 together, so as to prevent the two protective plates 33 from moving in opposite directions when laying cables.

[0043] Reference Figure 1 and Figure 3A scale 4 is fixed on the surface of the connecting plate 31. The length direction of the scale 4 is the same as that of the connecting plate 31, and the connecting block 321 is aligned with the middle position of the scale 4. During the installation of multiple connecting plates 31, the staff can adjust the horizontal distance between adjacent connecting plates 31 according to the measured horizontal error data between the main cable tray 1 and the corner cable tray 2. During the adjustment, the data on the scale 4 can be observed to allow the adjacent connecting plates 31 to move horizontally by a fixed distance, so as to avoid large fluctuations in the horizontal displacement difference between two adjacent connecting plates 31 and prevent the cable from bending at a large angle. Protective pads 5 are laid on multiple protective plates 33 at both ends of the connecting plate 31. The protective pads 5 are made of flexible and insulating materials. The length of the protective pads 5 is greater than the length of the multiple connecting plates 31 after splicing. The two ends of the protective pads 5 are connected and fixed to the protective plates 33 located at the two ends of the multiple protective plates 33, so that the middle of the protective pads 5 can have a large deformation margin. When adjusting the horizontal distance of the multiple connecting plates 31, the protective pads 5 can be made to fit on each protective plate 33. The protective pads 5 not only prevent the protective plates 33 from scratching the cable surface, but also allow the U-shaped structure formed by the connecting plates 31 and the protective plates 33 to form a closed structure as much as possible, preventing external debris from falling onto the laid cable. At the same time, protective pads 5 with the same structure and material are laid on the surface of the multiple connecting plates 31. They can be placed under the laid cable to prevent the locking bolts 343 and fixing bolts 322 from scratching the cable surface. A closed cover assembly is also provided above the connecting device 3. The cover assembly includes the same structural parts as the connecting plate 31, the protective plate 33, the connecting member 32 and the telescopic member 34. The cover assembly can be adjusted according to the horizontal adjustment distance of the connecting plate 31. After the cable is laid, the cover assembly is fastened above the cable to achieve a closed environment.

[0044] The implementation principle of a cable tray structure applicable to cable flipping in this application embodiment is as follows: During the installation of the cable tray, the main cable tray 1 and the corner cable tray 2 are connected and fixed by the connection device 3. During installation, according to the measured horizontal and vertical displacement lengths between the main cable tray 1 and the corner cable tray 2, different numbers of connecting plates 31 are selected, and the horizontal displacement between two adjacent connecting plates 31 is slidably adjusted so that the two ends of multiple connecting plates 31 can be connected to the main cable tray 1 and the corner cable tray 2.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
