Description

Technical Field

[0001] This utility model relates to the field of support device technology, specifically a cable tray support device. Background Technology

[0002] Cable tray support systems, as an important component of power systems and modern buildings, have emerged and developed in close relation to the needs of cable laying. With the rapid development of power, communication, and data networks, the number and types of cables are constantly increasing, making the safe, orderly, and efficient arrangement of these cables a critical issue. Cable tray support systems have emerged to address this need, providing not only stable support but also protecting cables from environmental damage, optimizing cable laying layout, and improving space utilization.

[0003] Patent CN220964273U discloses a cable tray support device, including a base with multiple cable tray bodies placed on top. Support mechanisms are located on both the front and rear sides of the base, each including a transmission box fixedly connected to the front and rear sides of the base. A rotating shaft is movably connected to the left side of the transmission box via a bearing, and the right side of the rotating shaft is movably connected to the inner wall of the transmission box via a bearing. In this support device, rotating a knob drives the rotating shaft to rotate, which in turn drives a gear. The gear, through tooth meshing, moves a toothed plate downwards. The toothed plate then penetrates the inner cavity of a pre-reserved groove and extends to the bottom of the transmission box. Simultaneously, an electric telescopic rod extends and moves a support block inwards, bringing the top of the support block into contact with the bottom of the base, thus providing support and preventing it from falling.

[0004] However, the above technology still has the following problems:

[0005] The width and thickness of cable trays are not exactly the same, and each cable tray can only bear a limited number of cables. The above technology is not convenient for installing and fixing cable trays of different sizes, and it lacks left and right position restrictions, which makes it easy to shake during use. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides a cable tray support device that can adjust the width and other dimensions according to the size of multiple cable trays and reduce swaying in the left and right directions.

[0007] This utility model provides the following technical solution: a cable tray support device, including a support rod, a threaded hole at the upper end of the support rod, a sliding cavity at the lower end of the support rod, a threaded rod threadedly connected to the threaded hole, a base plate fixedly connected to the threaded rod, a plurality of circular holes communicating with the sliding cavity on the side wall of the support rod, a sliding rod slidably connected inside the sliding cavity, a fixing mechanism adapted to the circular holes inside the sliding rod, a support plate first fixedly connected to the lower end of the support rod, a support plate second fixedly connected to the lower end of the sliding rod, a fixing seat fixedly connected to the support plate first, a fixing component detachably connected to the fixing seat, and an auxiliary support component fixedly connected to the outer wall of the support rod.

[0008] Furthermore, the fixing mechanism includes a slide groove 1 formed on the slide rod, a spring fixedly connected to the inner wall of the slide groove 1, and an insert rod fixedly connected to the output end of the spring.

[0009] Furthermore, the fixing base includes two fixing plates fixedly connected to the support rod and the support plate one. The inner surfaces of the two fixing plates are provided with sliding grooves two, and the surface of one of the fixing plates is provided with a through hole communicating with the sliding grooves two.

[0010] Furthermore, the fixing component includes a U-shaped plate, with sliders adapted to the slide groove fixedly connected to both sides of the U-shaped plate, and the sliders are threadedly connected with hexagonal bolts.

[0011] Furthermore, the auxiliary support assembly includes two rotating blocks 1 fixedly connected to the support rod, a rotating shaft 1 rotatably connected to the two rotating blocks 1, a connecting rod fixedly connected to the rotating shaft 1, a rotating shaft 2 fixedly connected to the upper end of the connecting rod, rotating blocks 2 fixedly connected to both sides of the rotating shaft 2, and a chassis 2 fixedly connected to the upper end of the two rotating blocks 2.

[0012] Furthermore, anti-slip and wear-resistant pads are fixedly connected to the upper surfaces of the first and second support plates and the upper and lower surfaces of the U-shaped plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This type of cable tray support device can be adjusted in width according to different cable tray sizes, and can simultaneously fix and support up to three cable trays.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1 to 5 A cable tray support device includes a support rod 1, a threaded hole 2 at the upper end of the support rod 1, a sliding cavity 3 at the lower end of the support rod 1, a threaded rod 4 threadedly connected to the threaded hole 2, a base plate 5 fixedly connected to the threaded rod 4, a plurality of circular holes 6 communicating with the sliding cavity 3 on the side wall of the support rod 1, a sliding rod 7 slidably connected inside the sliding cavity 3, a fixing mechanism adapted to the circular holes 6 inside the sliding rod 7, a support plate 8 fixedly connected to the lower end of the support rod 1, a support plate 9 fixedly connected to the lower end of the sliding rod 7, a fixing seat fixedly connected to the support plate 8, a fixing component detachably connected to the fixing seat, and an auxiliary support component fixedly connected to the outer wall of the support rod 1.

[0023] The cable tray support device in this utility model is similar in structure to existing cable tray support devices, such as the cable tray support device disclosed in patent CN220964273U. The main improvement of this utility model lies in the design of the fixing base and fixing components, which allows for the fixing of multiple cable trays. Furthermore, with the assistance of the auxiliary support components, the possibility of swaying in this support device is reduced, thus making the cable trays more stable after fixing. Figures 1 to 5As shown, in use, the cable tray support device of this utility model first fixes the base 5 to the top wall surface with expansion screws. Then, according to the size of the cable tray, the other support device base 5 is also fixed to the top wall surface with expansion screws. At this time, the two support devices are symmetrical about the cable tray, and the distance between the two fixing seats is the same as the width of the cable tray. When it is necessary to fix a cable tray, first move the U-shaped plate 16 upward, then place the cable tray on the support plate 8, and then move the U-shaped plate 16 downward. When the lower surface of the U-shaped plate 16 is in contact with the upper surface of the cable tray... After surface contact, the hexagonal bolt 18 is threaded through the through hole 15 and connected to the U-shaped plate 16. The hexagonal bolt 18 abuts against the surface of the fixing plate 13, thereby fixing the U-shaped plate 16 and preventing the cable tray from moving in either the horizontal or vertical direction. When it is necessary to fix two cable trays of different sizes, first press the insert rod 12 inward. The spring 11 is compressed and stores energy. At this time, the insert rod 12 is no longer located in the round hole 6, and the support plate 2 9 can be moved downward. After adjusting the distance between the support plate 1 8 and the support plate 2 9, the insert rod 12 moves downward under the action of the spring 11. Move the slide bar outward and slide it back into the round hole 6 to fix the slide rod 7, thus fixing the distance between the second support plate 9 and the first support plate 8. This prevents the wider cable tray from being fixed. The narrower cable tray is placed on the first support plate 8 in the same way. Then adjust the position of the U-shaped plate 16 to fix the narrower cable tray. When it is necessary to fix two or three cable trays of the same size, follow the same operation to place the three cable trays on the second support plate 9 in sequence, and fix the first support plate 8 to the upper surface of the U-shaped plate 16. The fixing operation is the same as the above operation, and will not be described in detail again. When fixing two identical cable trays, use support plate 8 and U-shaped plate 16 as support points. Alternatively, before fixing the cable trays, rotate threaded rod 4 to adjust the fixing height. After the threaded rod 4 is adjusted, fix the support device. After fixing the cable trays, rotate connecting rod 21 upward so that base plate 24 is in contact with the top surface of the cavity. Then use expansion screws to fix it. This provides auxiliary support for support rod 1 in the left and right directions, thereby reducing the possibility of the cable trays swaying left and right.

[0024] like Figure 5 As shown, the fixing mechanism includes a slide groove 10 formed on the slide rod 7, a spring 11 fixedly connected to the inner wall of the slide groove 10, and an insert rod 12 fixedly connected to the output end of the spring 11.

[0025] Specifically, when the insertion rod 12 is pressed inward, the spring 11 is compressed and stores energy. At this time, the insertion rod 12 is no longer located in the round hole 6, so the support plate 2 9 can be moved downward. After the distance between the support plate 1 8 and the support plate 2 9 is adjusted, the insertion rod 12 moves outward under the action of the spring 11 and slides back into the round hole 6, thereby fixing the slide rod 7.

[0026] like Figure 4 As shown, the fixing base includes two fixing plates 13 fixedly connected to the support rod 1 and the support plate 8. The inner surfaces of the two fixing plates 13 are provided with sliding grooves 14, and the surface of one of the fixing plates 13 is provided with a through hole 15 that communicates with the sliding grooves 14.

[0027] Specifically, the fixing plate 13 and the slide groove 14 are used to restrict the fixing components so that they can move in the vertical direction, so as to ensure that the upper and lower surfaces of the U-shaped plate 16 are in a horizontal state, thereby facilitating the fixing and support of the cable tray. The through hole 15 is also used for the hexagonal bolt 18 to be threadedly connected to the U-shaped plate 16.

[0028] like Figure 1 and Figure 3 As shown, the fixing component includes a U-shaped plate 16, and sliders 17 adapted to slide groove 14 are fixedly connected to both sides of the U-shaped plate 16. The sliders 17 are threadedly connected to hexagonal bolts 18.

[0029] Specifically, first, the sliders 17 on both sides of the U-shaped plate 16 are moved upward along the second slide groove 14. Then, the cable tray is placed on the first support plate 8. Next, the U-shaped plate 16 is moved downward. When the lower surface of the U-shaped plate 16 contacts the upper surface of the cable tray, the hexagonal bolts 18 are threaded through the through hole 15 and connected to the U-shaped plate 16. The hexagonal bolts 18 abut against the surface of the fixing plate 13, thereby fixing the U-shaped plate 16, so that the cable tray cannot move in either the horizontal or vertical direction.

[0030] like Figure 2 As shown, the auxiliary support assembly includes two rotating blocks 19 fixedly connected to the support rod 1. A rotating shaft 20 is rotatably connected to the two rotating blocks 19. A connecting rod 21 is fixedly connected to the rotating shaft 20. A rotating shaft 22 is fixedly connected to the upper end of the connecting rod 21. Rotating blocks 23 are fixedly connected to both sides of the rotating shaft 22. A chassis 24 is fixedly connected to the upper end of the two rotating blocks 23.

[0031] Specifically, after the threaded rod 4 is adjusted, the support device is fixed. After the cable tray is fixed, the connecting rod 21 is rotated upward so that the base plate 24 is in contact with the top surface of the cavity. Then, expansion screws are used to fix it. This provides auxiliary support for the support rod 1 in the left and right directions, thereby reducing the possibility of the cable tray swaying left and right.

[0032] like Figure 2 As shown, the upper surfaces of the support plate 1 8 and the support plate 2 9, as well as the upper and lower surfaces of the U-shaped plate 16, are all fixedly connected with anti-slip and wear-resistant pads.

[0033] Specifically, the anti-slip and wear-resistant pad can increase the friction between the upper surfaces of support plate 18 and support plate 29, as well as the upper and lower surfaces of U-shaped plate 16 and the cable tray, thereby improving the fixing effect of the cable tray.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
