Description

Technical Field

[0001] This utility model relates to the field of cable tray support technology, and in particular to a cable tray support structure. Background Technology

[0002] Cable tray support arms are key load-bearing connectors in cable tray systems, bearing the important mission of safely transferring cable trays and their loads (cable weight, additional loads, etc.) to the building structure. Their main body is usually made of high-strength steel plates through stamping and bending, or made of shaped steel, and the surface is hot-dip galvanized to provide long-term corrosion protection. The core structure includes the load-bearing arm body, the cable tray connection end, and the support structure connection end.

[0003] Chinese Patent No. CN219498822U discloses a hanging cable tray support arm, which adapts to the installation at the edge of a building by setting a right-angle base on one side of the horizontal support arm. The inventor found that although the device solves the problem of cable tray support arms being inconvenient to fix and install in special installation situations, the presence of the right-angle base also makes it difficult to fix the device to the wall, thus limiting its applicability. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cable tray support structure that solves the problem that existing cable tray supports cannot adapt to different installation conditions and have a limited range of applications.

[0005] According to an embodiment of this utility model, a cable tray support structure includes a mounting plate and extension plates. A horizontal plate is detachably provided on one side of the mounting plate, and a receiving platform is detachably provided on the other side of the mounting plate. The receiving platform includes a base plate and two wing plates, which are symmetrically arranged at both ends of the base plate. A plurality of mounting holes are provided at equal intervals along the height direction of the mounting plate. A plurality of connecting holes are provided along the length direction of one of the wing plates. The receiving platform is detachably connected to the mounting plate through the connecting holes. A plurality of extension plates are provided on the outer wall of each wing plate, and each extension plate is provided with a lifting hole.

[0006] Compared with existing technologies, this utility model has the following advantages: By detachably connecting the mounting plate, the horizontal plate, and the receiving platform, when the device is installed at the edge of a building, the horizontal plate is connected to the mounting plate to form a right-angle structure, and the horizontal plate is fixed to the building to complete the installation. When installed on a wall, the horizontal plate is removed, and the mounting plate is fixed to the wall to ensure safety. The mounting holes on the mounting plate facilitate the adjustment of the height of the receiving platform. When dealing with the working conditions of suspended cables, the mounting plate is installed on the building ceiling, and then the mounting plate is connected to the extension plate through the connecting line. This device can be applied to different cable tray working conditions, and workers do not need to prepare different cable tray support arms when facing different working conditions, thus speeding up the construction progress.

[0007] Furthermore, it also includes several diagonal braces, each with a connecting plate at both ends, and the two connecting plates are detachably connected to the mounting plate and the support platform, respectively.

[0008] Furthermore, each wing plate has several grooves on its outer wall, each extension plate is slidably disposed in the corresponding groove, and each extension plate is also provided with a limiting component to restrict its sliding.

[0009] Furthermore, each limiting component includes a limiting post and a spring. Each extension plate has a mounting groove at its bottom. The limiting post is slidably disposed in the mounting groove. One end of the spring is fixedly connected to the inner wall of the mounting groove, and the other end of the spring is fixedly connected to the limiting post. The bottom of the receiving platform has several insertion holes for the limiting post to be inserted.

[0010] Furthermore, several ventilation holes are provided on the receiving platform.

[0011] Furthermore, each wing plate is provided with a guide groove at the position of the slide groove.

[0012] Furthermore, the top of the base plate has several arc-shaped recesses. Attached Figure Description

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1 to 3As shown in the figure, this utility model embodiment proposes a cable tray support structure, including a mounting plate 1 and an extension plate 6. A horizontal plate 2 is detachably provided on one side of the mounting plate 1, and a receiving platform 3 is detachably provided on the other side of the mounting plate 1. The receiving platform 3 includes a base plate 301 and two wing plates 302. The two wing plates 302 are symmetrically arranged at both ends of the base plate 301. A plurality of mounting holes 4 are provided at equal intervals along the height direction of the mounting plate 1. A plurality of connecting holes 5 are provided along the length direction of one of the wing plates 302. The receiving platform 3 is detachably connected to the mounting plate 1 through the connecting holes 5. A plurality of extension plates 6 are provided on the outer wall of each wing plate 302, and each extension plate 6 is provided with a lifting hole. The receiving platform 3 has a concave cross-section. In this embodiment, the mounting plate 1 and the horizontal plate 2 can be connected by screws or bolts for easy removal. When installing at the edge of a building, the mounting plate 1 and the horizontal plate 2 are connected and fixed. Then, the receiving platform 3 and the mounting plate 1 are fixed by bolts passing through the connecting hole 5 of one of the wing plates 302 of the receiving platform 3 and the mounting hole 4 on the mounting plate 1. The mounting holes 4 on the mounting plate 1, arranged along the height direction, facilitate the adjustment of the installation height of the receiving platform 3. The horizontal plate 2 is fixed to the building in any way available in the prior art. This allows for easy installation of the device at the building's edge. When mounting on a wall, simply remove the horizontal plate 2 and secure it to the wall using bolts or screws through the mounting holes 4 on the mounting plate 1. For situations requiring cable slinging, fix the mounting plate 1 to the building's ceiling. Simultaneously, thread a connecting wire through the mounting holes 4, connecting one end to the mounting plate 1 and the other end through the suspension hole on the extension plate 6, thus suspending the receiving platform 3 to meet the cable slinging requirements. It should be noted that in the first two scenarios, a receiving groove for the extension plate 6 can be provided on the mounting plate 1 to prevent interference between the extension plate 6 on the wing plate 302 near the mounting plate 1 and the mounting plate 1. Through the detachable connections of the various components and the presence of the extension plate 6, the device can meet different working conditions by reducing the number of components and changing the connection relationships between them, thus offering a wide range of applications.

[0021] like Figure 2 As shown, furthermore, it also includes several diagonal braces 7, each of which has a connecting plate 8 at both ends. The two connecting plates 8 are detachably connected to the mounting plate 1 and the support platform 3, respectively. Specifically, in the two installation conditions of facing the edge of a building or the wall, the two connecting plates 8 are fixed to the side wall of the mounting plate 1 and the bottom of the support platform 3 by screws, so that the diagonal braces 7 can play a triangular support role and improve the load-bearing capacity of the support platform 3.

[0022] like Figure 4As shown, furthermore, each wing plate 302 has several grooves on its outer wall, and each extension plate 6 is slidably disposed in the corresponding groove. Each extension plate 6 is also provided with a limiting component to restrict its sliding. In this embodiment, the number of extension plates 6 corresponds one-to-one with the number of grooves. The extension plates 6 are slidably disposed in the grooves, thereby storing the extension plates 6 through the grooves. When the extension plates 6 are not in use, they can be pushed into the grooves to protect them. When the extension plates 6 are needed to suspend the receiving platform 3, they can be pulled out of the grooves, and the movement of the extension plates 6 is restricted by the limiting components to prevent the cables from swaying due to the sliding between the extension plates 6 and the grooves after the cables are laid.

[0023] like Figure 4 As shown, each limiting component further includes a limiting post 9 and a spring 10. Each extension plate 6 has a mounting groove at its bottom. The limiting post 9 is slidably disposed within the mounting groove. One end of the spring 10 is fixedly connected to the inner wall of the mounting groove, and the other end of the spring 10 is fixedly connected to the limiting post 9. The bottom of the receiving platform 3 has several insertion holes 11 for the limiting post 9 to be inserted. Under the push of the spring 10, one end of the limiting post 9 tends to extend out of the mounting groove. When the extension plate 6 is pulled to move until the mounting groove corresponds to the insertion hole 11, the limiting post 9 is inserted into the insertion hole 11 under the push of the spring 10, thereby restricting the movement of the extension plate 6. When the extension plate 6 needs to be moved again, the limiting post 9 is pressed towards the mounting groove from the bottom of the receiving platform 3, and then the extension plate 6 is moved.

[0024] like Figure 1 and Figure 2 As shown, the receiving platform 3 is further provided with several ventilation holes 12. When the cable transmits current, it will generate Joule heat. Especially in high voltage, high current or dense laying scenarios, the internal temperature of the cable tray may rise to more than 60°C. The ventilation holes 12 promote air convection, accelerate heat dissipation, and slow down the aging rate of the cable insulation layer.

[0025] like Figure 5 As shown, each wing plate 302 is further provided with a guide groove 13 at the position of the slide groove. In this embodiment, each wing plate 302 is provided with a vent hole 12 above the guide groove 13. The guide groove 13 is connected to the vent hole 12. In order to fix the cable, cable ties or straps are often used. The cable tie is inserted into the vent hole 12 and bypasses the guide groove 13, so that the cable tie can bind and fix the cable. The presence of the guide groove 13 restricts the horizontal displacement of the cable tie, and at the same time allows one end of the extension plate 6 to be exposed, which facilitates the operation of the extension plate 6.

[0026] like Figure 3As shown, furthermore, the top of the base plate 301 is provided with several arc-shaped recesses 14. Specifically, the arc-shaped recesses 14 are provided along the length direction of the base plate 301. The cable is placed on the base plate 301 of the receiving platform 3. The presence of the arc-shaped recesses 14 allows the cable to be embedded in the arc-shaped recesses 14, making it less likely for the cable to undergo large displacement.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
