Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0043] The following is combined Figures 1 to 5 This invention describes a cable tray support device.

[0044] like Figures 1 to 5 As shown in the figure, the cable tray support device provided in this embodiment of the present invention includes a mounting bracket 1, a connecting bracket and a first driving component.

[0045] Specifically, the mounting bracket 1 is used to connect with the target component. Specifically, a first connecting hole 13 can be provided on the mounting bracket 1, and bolts can be used to fix the mounting bracket 1 to the target component.

[0046] The connecting bracket is used to connect the cable tray 2. The connecting bracket is rotatably mounted on the mounting bracket 1, and the axis of rotation of the connecting bracket relative to the mounting bracket 1 is perpendicular to the cable support surface 3 of the cable tray 2. When the connecting bracket rotates relative to the mounting bracket 1, it can drive the cable tray 2 to rotate relative to the mounting bracket 1. The first driving member is used to drive the connecting bracket to rotate relative to the mounting bracket 1.

[0047] This configuration connects the mounting bracket 1 to the target component and the connecting bracket to the cable tray 2. By using the first driving component to rotate the connecting bracket relative to the mounting bracket 1, the cable tray 2 can be rotated relative to the target component, thereby adjusting the direction of the cable tray 2 to match the target laying direction of the cable. This solves the problem in related technologies where the support device for cable trays cannot adjust the direction of the cable tray according to the laying direction of the cable, and improves the adaptability of the cable tray support device to the laying direction of the cable.

[0048] In this embodiment, the cable tray support device further includes a first transmission mechanism, which is disposed between the connecting bracket and the mounting bracket 1. The input end of the first transmission mechanism is connected to the first driving member, and the output end of the first transmission mechanism is connected to the connecting bracket.

[0049] With this configuration, the first driving component is connected to the connecting bracket via the first transmission mechanism, which facilitates determining the placement of the first driving component based on the spatial distribution around the connecting bracket and the mounting bracket 1.

[0050] The first transmission mechanism includes a gear 4, a rack 5, and a first transmission rod 6.

[0051] Gear 4 is rotatably mounted on mounting bracket 1, and the axis of rotation of gear 4 relative to mounting bracket 1 is perpendicular to the cable support surface 3 of cable tray 2. The connecting bracket is fixedly connected to gear 4.

[0052] Specifically, the connecting bracket can be inserted inside the gear 4, making the connecting bracket and gear 4 coaxial. In this case, the gear 4 has a through hole at its center, and the connecting bracket is located inside the through hole. A mounting ring groove is provided within the mounting bracket 1, and the edge of the gear 4 is located within the mounting ring groove. A positioning ring groove is provided at the position of the mounting ring groove corresponding to the end face of the gear 4. A positioning protrusion 14 is provided on the end face of the gear 4, and the central axis of the positioning protrusion 14, the central axis of the positioning ring groove, and the central axis of the gear 4 coincide. The positioning protrusion 14 is located inside the positioning ring groove. When the gear 4 rotates relative to the mounting bracket 1, the positioning protrusion 14 rotates relative to the positioning ring groove within the positioning ring groove. The cooperation between the positioning protrusion 14 and the positioning ring groove enables the rotatable mounting of the gear 4, which has a through hole at its center, on the mounting bracket 1.

[0053] The rack 5 is mounted on the mounting bracket 1 in a reciprocating sliding manner. The rack 5 meshes with the gear 4 for transmission. The reciprocating sliding of the rack 5 relative to the mounting bracket 1 enables the gear 4 to rotate reciprocally relative to the mounting bracket 1.

[0054] The rack 5 can only slide back and forth relative to the mounting bracket 1; it cannot rotate relative to the mounting bracket 1. Specifically, a groove is provided inside the mounting bracket 1, the groove having a rectangular cross-section, and the rack 5 slides in contact with the side wall of the groove.

[0055] The first transmission rod 6 passes through the inside of the rack 5 and is threadedly engaged with the rack 5. The end of the first transmission rod 6 is rotatably connected to the mounting bracket 1, and the end of the first transmission rod 6 extends to the outside of the mounting bracket 1 and is connected to the first driving member, which is used to drive the first transmission rod 6 to rotate relative to the mounting bracket 1.

[0056] The first drive member causes the first transmission rod 6 to rotate relative to the mounting bracket 1, thereby driving the rack 5 to slide relative to the mounting bracket 1, which in turn drives the gear 4 to rotate relative to the mounting bracket 1, and in turn drives the connecting bracket to rotate relative to the mounting bracket 1.

[0057] In this embodiment, the first driving component includes a first rotary handle 7 or a first drive motor.

[0058] When the first driving component includes a first rotating handle 7, the first rotating handle 7 is fixedly connected to the end of the first transmission rod 6. The first rotating handle 7 can apply torque to the first transmission rod 6, thereby causing the first transmission rod 6 to rotate relative to the rack 5 and the mounting bracket 1.

[0059] When the first driving component includes a first driving motor, the housing of the first driving motor is fixed relative to the mounting bracket 1, and the output shaft of the first driving motor is connected to the end of the first transmission rod 6. When the first driving motor is running, the first transmission rod 6 can rotate relative to the rack 5 and the mounting bracket 1.

[0060] In this embodiment of the invention, the length of the connecting bracket is adjustable, and the direction of extension and retraction of the connecting bracket is parallel to the rotation axis of the first bracket 8 relative to the mounting bracket 1. By adjusting the extension and retraction of the connecting bracket, the cable tray 2 can be moved in a direction perpendicular to the cable support surface 3 of the cable tray 2. The cable support surface 3 of the cable tray 2 is generally arranged horizontally; therefore, the extension and retraction adjustment of the connecting bracket enables the cable tray 2 to be raised and lowered.

[0061] Specifically, the connecting bracket includes a first bracket 8, a second bracket 9, and a second driving component.

[0062] The first bracket 8 is rotatably engaged with the mounting bracket 1. Specifically, the end of the first bracket 8 closest to the mounting bracket 1 can be fixedly connected to the gear 4.

[0063] The second bracket 9 is slidably engaged with the first bracket 8, and the sliding direction of the second bracket 9 relative to the first bracket 8 is parallel to the rotation axis of the first bracket 8 relative to the mounting bracket 1. The second driving member is used to drive the second bracket 9 to slide back and forth relative to the first bracket 8.

[0064] By using the second driving component to make the second bracket 9 slide relative to the first bracket 8, the telescopic adjustment of the connecting bracket can be realized, thereby realizing the lifting and lowering adjustment of the cable tray 2.

[0065] In this embodiment, the connecting bracket further includes a second transmission mechanism, which is disposed between the second bracket 9 and the first bracket 8. The input end of the second transmission mechanism is connected to the second driving member, and the output end of the second transmission mechanism is connected to the second bracket 9.

[0066] With this configuration, the second drive component is connected to the second bracket 9 via the second transmission mechanism, which facilitates determining the placement of the second drive component based on the spatial distribution around the connecting bracket and the mounting bracket 1.

[0067] The second support 9 can only slide back and forth relative to the first support 8, and cannot rotate relative to the first support 8. Specifically, both the first support 8 and the second support 9 are tubular, so that the first support 8 and the second support 9 are fitted together, and the cross-sectional shape of the first support 8 and the second support 9 is set to be rectangular.

[0068] In this embodiment, the first bracket 8 is fitted over the second bracket 9.

[0069] The second transmission mechanism includes a second transmission rod 10, which passes through the interior of the second bracket 9 and is threadedly engaged with the second bracket 9. The end of the second transmission rod 10 is rotatably connected to the first bracket 8, and a second driving member is drively connected to the end of the second transmission rod 10, driving the second transmission rod 10 to rotate relative to the first bracket 8.

[0070] The second drive member causes the second transmission rod 10 to rotate relative to the first bracket 8, thereby driving the second bracket 9 to slide relative to the first bracket 8, which in turn causes the cable tray 2 to slide relative to the first bracket 8 and the mounting bracket 1.

[0071] In this embodiment, the second driving component includes a second rotary handle 11 or a second drive motor.

[0072] When the second driving component includes the second rotating handle 11, the second rotating handle 11 is fixedly connected to the end of the second transmission rod 10. The second rotating handle 11 can apply torque to the second transmission rod 10, thereby causing the second transmission rod 10 to rotate relative to the mounting bracket 1 and the first bracket 8.

[0073] When the second driving component includes a second driving motor, the housing of the second driving motor is fixed relative to the first bracket 8, and the output shaft of the second driving motor is connected to the end of the second transmission rod 10. When the second driving motor is running, the second transmission rod 10 can rotate relative to the mounting bracket 1 and the first bracket 8.

[0074] To facilitate the placement of the second drive component and avoid interference between the second drive component and the mounting bracket 1, a clearance space 15 is provided on the mounting bracket 1. The clearance space 15 is used to allow the second drive component to pass. Figure 1 As shown, the mounting bracket 1 is configured as a frame structure, with the two opposite sides of the frame structure serving as the first connecting part and the second connecting part, respectively. The first connecting part is used to connect with the target component, and the second connecting part is used to connect with the connecting bracket.

[0075] In this embodiment of the invention, the connecting bracket further includes a third bracket 12, which is fixedly connected to the end of the second bracket 9. The extending direction of the third bracket 12 is perpendicular to the sliding direction of the second bracket 9 relative to the first bracket 8. The third bracket 12 is connected to the cable tray 2.

[0076] Specifically, a second connection hole can be provided on the third bracket 12, the cable tray 2 can be placed on top of the third bracket 12, and the cable tray 2 can be fixedly connected to the third bracket 12 with bolts. The third bracket 12 can support the cable tray 2.

[0077] In this embodiment, a limiting structure is provided between the first support 8 and the second support 9. The limiting structure is used to limit the sliding range of the second support 9 relative to the first support 8, so as to prevent the second support 9 from falling off the first support 8.

[0078] Specifically, the limiting structure includes a limiting groove 16 and a limiting block 17, with the limiting block 17 slidingly engaging with the limiting groove 16. The limiting groove 16 is disposed on the side wall of the first bracket 8, and the extending direction of the limiting groove 16 is parallel to the sliding direction of the second bracket 9 relative to the first bracket 8. The limiting block 17 is fixedly disposed on the side wall of the second bracket 9. Through the sliding engagement between the limiting block 17 and the limiting groove 16, the sliding of the second bracket 9 relative to the first bracket 8 can be guided. Moreover, the interaction between the ends of the limiting block 17 and the limiting groove 16 can limit the sliding range of the limiting block 17.

[0079] In summary, the cable tray support device provided in this embodiment of the invention, through the rotation of the connecting bracket relative to the mounting bracket 1 caused by the first driving component, can achieve directional adjustment of the cable tray 2 to adapt to the cable laying direction. Through the extension and retraction adjustment of the connecting bracket caused by the second driving component, the height of the cable tray 2 can be adjusted to adapt to the cable laying height and to accommodate installation environments with varying heights. Combining the directional and height adjustments of the cable tray 2, multi-directional adjustment of the cable tray 2 is achieved.
