[0018] The following specific implementation content provides various different embodiments or examples for implementing the present utility model. Of course, these are only embodiments or examples and are not intended to be restrictive. Additionally, repeated reference numerals may be used in different embodiments, such as repeated numbers and / or letters. These repetitions are for the purpose of simply and clearly describing the present utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0019] Such as Figures 1-3An adjustable combined large-span cable tray is shown, which includes a support box body 1 communicating left and right. On the left and right ends of the support box body 1, cable trays 2 slide respectively. On the lower sides of the two cable trays 2, sliders 3 are arranged. On the lower side of the support box body 1, a horizontal chute 4 is arranged. The sliders 3 slide left and right in the horizontal chute 4. On the lower side of the support box body 1, an adjustment driving mechanism is also arranged. The adjustment driving mechanism can drive the two sliders 3 to slide inward or outward relative to each other simultaneously.

[0020] In the present utility model, through the setting of the support box body 1, the cable trays 2 on the left and right sides are slidably arranged in the support box body 1. Thus, no matter how the cable trays 2 expand or contract, one end of the two cable trays 2 will be inside the support box body 1, and the overall stability is relatively high, which can better protect the cables. Moreover, the structure is simple and the operation is convenient. The distance between the two cable trays 2 can be adjusted, so as to be applicable to the laying of cables with different lengths.

[0021] Certainly, the upper end of the support box body 1 has an openable end cover. When laying cables, the end cover can be opened, so as to facilitate the laying of cables.

[0022] In order to ensure that the cable trays 2 can slide smoothly, slider flanges 81 are arranged on the left and right sides inside the support box body 1, and horizontal slide rails 82 are arranged on the left and right sides of the cable trays 2. The slider flanges 81 slide in the horizontal slide rails 82. The slider flanges 81 are fixed to the inner wall of the support box body 1 by welding, while the horizontal slide rails 82 are integrally formed with the cable trays 2 by stamping and bending.

[0023] See Figure 2 、 Figure 3 As shown, the adjustment driving mechanism includes a vertical shaft 21 rotatably arranged on the lower side of the support box body 1. A turntable 22 is arranged on the vertical shaft 21. Connecting rods 23 are hinged to the lower sides of the two sliders 3 respectively, and the other ends of the two connecting rods 23 are hinged to the turntable 22. When the turntable 22 rotates, the sliders 3 are driven to slide in the horizontal chute 4 through the connecting rods 23, thereby driving the cable trays 2 to move, and realizing the contraction or elongation of the cable trays 2 on the left and right sides.

[0024] Further, a worm gear 31 is also arranged on the vertical shaft 21. A support seat 32 is arranged on the lower side of the support box body 1. A horizontal shaft 33 is rotatably installed on the support seat 32. A worm 34 meshing with the worm gear 31 is arranged on the horizontal shaft 33. Through the cooperation of the worm 34 and the worm gear 31, the worm gear 31 rotates, and the rotation of the worm gear 31 drives the vertical shaft 21 and the turntable 22 to rotate, realizing the driving of the cable trays 2 on both sides to slide. The overall structure is simple and the operation is convenient.

[0025] It is worth mentioning that, due to the self-locking function of the worm wheel 31 and the worm 34, after adjustment, the bridge 2 can be automatically locked.

[0026] Furthermore, one end of the horizontal shaft 33 is provided with an internal hexagonal bolt head 51. By cooperating with the internal hexagonal bolt head 51 using a hexagonal wrench, it is convenient to drive the horizontal shaft 33 to rotate.

[0027] See Figure 1 , Figure 2 As shown, a protective box body 41 is provided on the lower side of the support box body 1, and the turntable 22 is arranged inside the protective box body 41.

[0028] Furthermore, one end of the horizontal shaft 33 extends outside the protective box body 41 and is provided with an internal hexagonal bolt head 51.

[0029] In the present utility model, a support column 61 is provided on the lower side of the protective box body 41, and a reinforcing plate 71 is connected between the support column 61 and the protective box body 41. It is installed on the use site through the support column 61.
