[0005] Existing cable tray support devices have the problem of inconvenient cable spacing adjustment during cable laying. Traditional structures are difficult to achieve synchronous and equidistant movement of multiple clamping points, resulting in uneven cable arrangement, which affects construction efficiency and quality. Especially in complex wiring situations where frequent cable spacing adjustments are required, operators often need to adjust each clamping point one by one, which is time-consuming and makes it difficult to ensure the consistency of spacing. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a cable tray support device for power construction. By driving a positioning mechanism through a rotation adjustment mechanism, multiple clamping units can move synchronously and at equal distances, ensuring that the cable spacing is uniform and adjustable, achieving neat cable arrangement, and improving construction efficiency and quality.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cable tray support device for power construction, comprising a cable tray, a positioning mechanism for cable positioning on the cable tray, and an adjustment mechanism for adjusting the positioning mechanism on the cable tray. The positioning mechanism includes:

[0008] The main component includes a bearing fixed at both the front and rear ends inside the cable tray, a shaft rotatably mounted between the two ends of the bearing, a number of guide grooves on the shaft, and a slide rod fixed between the two ends of the bearing;

[0009] The actuation component includes several sliders slidably mounted on a slide bar. A chuck is mounted on the upper end of each slider, and a protrusion is fixed to the bottom of the slider, with the protrusion located inside a guide groove.

[0010] Preferably, the adjustment mechanism includes a housing fixed to the outer wall of the cable tray, a worm gear rotatably mounted inside the housing and fixed to a shaft, a worm rotatably mounted between the two ends inside the housing and meshing with the worm gear for transmission, and a knob fixed to the outer end of the worm.

[0015] Beneficial effects

[0016] This utility model provides a cable tray support device for power construction. Compared with the prior art, it has the following advantages:

[0017] 1. Rotating the knob drives the worm gear to rotate, and the worm gear drives the shaft through the worm wheel. When the shaft rotates, the guide groove and the protrusion drive the slider to slide along the slide bar, so that each slider drives the corresponding clamp to move synchronously and equidistantly. The synchronous and equidistant movement of multiple clamps ensures the uniformity and accuracy of cable spacing adjustment, making the cables neat and beautiful.

[0018] 2. The groove contour fits snugly against the outer surface of the cable, ensuring clamping stability and preventing damage to the cable sheath; the grooves at both ends allow a single clamp to simultaneously secure two adjacent cables, effectively improving the space utilization of the cable tray; the mounting holes and bolt connections allow the clamps to be replaced according to the laying requirements of different cable specifications, greatly improving the applicability and flexibility of the device.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a cable tray support device for power construction, including a cable tray 1, a positioning mechanism 2 for cable positioning on the cable tray 1, and an adjustment mechanism 3 for adjusting the positioning mechanism 2 on the cable tray 1. The positioning mechanism 2 includes:

[0028] The main component 21 includes a bearing 211 fixed inside the cable tray 1 at both ends. A shaft 212 is rotatably mounted between the two ends of the bearing 211. Several guide grooves 213 are provided on the shaft 212. A slide rod 214 is fixed between the two ends of the bearing 211.

[0029] The execution component 22 includes a plurality of sliders 221 slidably mounted on the slider 214. A chuck 222 is mounted on the upper end of the slider 221, and a protrusion 224 is fixed on the bottom of the slider 221, and the protrusion 224 is located inside the guide groove 213.

[0030] In this embodiment, when the shaft 212 rotates, the guide groove 213 and the protrusion 224 drive the slider 221 to slide along the slide bar 214, so that each slider 221 drives the corresponding clamp 222 to move synchronously and equidistantly; the synchronous and equidistant movement of multiple clamps 222 ensures the uniformity and accuracy of cable spacing adjustment, making the cables neat and beautiful.

[0031] Specifically, the adjustment mechanism 3 includes a housing 31 fixed to the outer wall of the cable tray 1. A worm gear 32 is rotatably installed inside the housing 31 and is fixed to the shaft 212. A worm 33 is rotatably installed between the two ends inside the housing 31 and meshes with the worm gear 32 for transmission. A knob 34 is fixed to the outer end of the worm 33.

[0032] In this embodiment, the worm gear 33 is rotated by rotating the knob 34, and the worm gear 33 drives the shaft 212 through the worm wheel 32; the external knob 34 design allows the operator to complete the adjustment without entering the cable tray 1.

[0033] Specifically, the execution component 22 also includes grooves 223 formed at both ends of the chuck 222.

[0034] In this embodiment, the contour of the groove 223 fits against the outer surface of the cable, ensuring the stability of the clamping and avoiding damage to the outer sheath of the cable; the groove 223 with both ends allows a single clamp 222 to fix two adjacent cables at the same time, effectively improving the space utilization of the cable tray 1.

[0035] Specifically, the execution component 22 also includes a mounting hole 225 formed on the chuck 222.

[0036] The chuck 222 is fixed to the slider 221 by bolts through the mounting hole 225.

[0037] In this embodiment, the clamp 222 can be replaced according to the laying requirements of different specifications of cables by using the mounting hole 225 and bolt connection, which greatly improves the applicability and flexibility of the device.

[0038] Specifically, several guide grooves 213 are symmetrically distributed on the outer wall of the shaft 212.

[0039] In this embodiment, when the shaft 212 rotates, the multiple sliders 221 located on the left and right sides of the slide bar 214 can achieve completely synchronized symmetrical movement.

[0040] Specifically, the guide groove 213 is an obliquely arranged spiral groove.

[0041] In this embodiment, the transmission method of converting rotational motion into linear motion by the spiral groove 213 is simple and reliable, without the need for additional complex transmission components; secondly, the obliquely arranged spiral groove 213 can ensure that multiple sliders 221 achieve synchronous and coordinated movement, so that the clamping force of the clamp 222 on the cable is uniform.

[0042] The working principle and usage process of this utility model are as follows: First, the worm gear 33 is rotated by rotating the knob 34, and the worm gear 33 drives the shaft 212 through the worm wheel 32; when the shaft 212 rotates, the slider 221 is driven to slide along the slide bar 214 through the guide groove 213 and the protrusion 224, so that each slider 221 drives the corresponding clamp 222 to move synchronously and equidistantly; the synchronous and equidistant movement of multiple clamps 222 ensures the uniformity and accuracy of the cable spacing adjustment, making the cables neat and beautiful.
