[0032] The vertical plate 12 is an isosceles trapezoidal steel plate, and the number is two, symmetrically installed on both sides of the bottom plate 11, and the vertical plate 12 is welded and connected perpendicularly to the long side of the bottom plate 11. Each vertical plate 12 is uniformly holed at different heights along the central axis, which is used for the installation of the roller shaft 52. The bottom plate 11 is a rectangular steel plate, and two circular holes are symmetrically arranged along the central axis of the long side, which are used for penetrating the half-round head bolt 41. The strip-shaped steel plate 31 is provided with a long hole along the central axis of the long side, and the hole width is the same as the diameter of the circular hole of the bottom plate 11. The width of the strip-shaped steel plate 31 is slightly smaller than the width of the bottom plate 11, and the length is slightly larger than the span of the two bridge cross supports, and the L-shaped angle steel 32 is welded and connected with the end of the strip-shaped steel plate 31 away from the support 1. The half-round head bolt 41 penetrates the strip-shaped steel plate 31, the bottom plate 11 and the first gasket 43 in sequence, and is fixed through the wing nut 42.

[0033] The limiting mechanism 2 is an L-shaped angle steel structure, which is welded at the bottom of the bottom plate 11 and located at the end of the bottom plate 11 away from the L-shaped angle steel 32, and forms a U-shaped cavity with the bottom plate 11. The cavity height is adapted to the height of the cable bridge cross support. The L-shaped angle steel 32 and the limiting mechanism 2 are of the same specification and are welded in opposite directions.

[0034] The number of the plane bearing 53 is two, which is symmetrically arranged on both sides of the roller 51, and each plane bearing 53 is located between the roller 51 and the vertical plate 12. The roller shaft 52 includes a long bolt 521, a matched nut 522 and a second gasket 523. The number of the second gasket 523 is two, which is symmetrically arranged on the outer side of the two vertical plates 12. One end of the long bolt 521 penetrates the first gasket 523, the vertical plate 12, the plane bearing 53, the roller 51, the plane bearing 53, the vertical plate 12, the first gasket 523 in sequence, and is fixed through the matched nut 522. The roller 51 is a concave plastic-coated bearing roller, and the central axes of the roller 51, the plane bearing 53 and the second gasket 523 coincide.

[0035] The utility model discloses a specific working process:

[0036] First, the locking mechanism 4 is loosened by unscrewing the wing nut 42, so that the support 1 is separated from the clamping mechanism 3. At this time, the clamping mechanism 3 can slide along the long hole on the strip-shaped steel plate 31. Through the cavity formed by the limiting mechanism 2 and the clamping mechanism 3, two adjacent cable bridge cross supports are clamped, and at the same time, each wing nut 42 is tightened, and the device is fixed on the cable bridge through the limiting mechanism 2. The cable to be laid is placed on the upper part of the roller mechanism 5, and the laying effect of the cable can be realized by pulling the movable end of the cable. At this time, the installation position of the roller mechanism 5 on the support vertical plate 12 can be selected according to the model of the cable.

[0037] Furthermore, to better prevent the cable from slipping out of the roller groove when dragging the cable, two roller mechanisms 5 are installed side by side on the vertical plate 12, forming a cavity between the two concave rollers 51. When the cable passes through this cavity, the two concave rollers 51 limit the cable displacement during subsequent dragging, effectively preventing the aforementioned problem and ensuring adequate cable protection. The two roller mechanisms 5 can be directly fixed through the openings on the vertical plate 12, thus achieving side-by-side installation. When the height of the vertical plate 12 is insufficient for side-by-side installation of the two roller mechanisms 5, two brackets with through holes are selected. The two brackets are respectively set on the outer side of the two vertical plates 12, with the through holes at one end of the brackets corresponding to the openings on the vertical plates. One end of the long bolt 521 passes through the two brackets, and the brackets and roller mechanisms 5 are fixed together with matching nuts 522.

[0039] like Figure 4 As shown, the structure of this embodiment is the same as that of embodiment 1. The difference is that this embodiment is installed under the cable tray to realize the suspended cable laying construction.
