Description

Technical Field

[0001] The utility model relates to a cable bridge, in particular to a ladder-type cable bridge. Background Art

[0002] Cable trays are divided into trough type, tray type, ladder type, grid type and other structures, which are composed of brackets, supports and installation accessories. The cable trays can be erected independently in buildings or attached to various buildings and pipe gallery brackets. They should have the characteristics of simple structure, beautiful appearance, flexible configuration and easy maintenance. All parts need to be galvanized and installed in the open air outside the building. Among them, the ladder type cable tray is suitable for the laying of cables with larger diameters, and is suitable for the laying of high and low voltage power cables.

[0003] At present, for the existing ladder-type cable trays, the existing ladder-type cable trays are basically formed by welding, so they occupy a large space during transportation and placement, which is not conducive to the transportation and storage of the ladder-type cable trays.

[0008] Furthermore, in order to rotate the rotating screw, a bevel gear 1 is fixedly connected to the rotating screw, a rotating rod is rotatably connected to one side of the inner surface of the driving cavity, a bevel gear 2 is fixedly connected to one end of the rotating rod, and the bevel gear 2 is meshed with the bevel gear 1.

[0009] Furthermore, in order to enable the sliding block to slide stably on the partition, a sliding groove is provided on the partition, and the sliding block is slidably connected to the sliding groove.

[0010] Furthermore, in order to make the clamping block slide stably on the bridging support rod, a T-shaped slot is provided on the top of the bridging support rod, and a T-shaped block is welded on the bottom end of the clamping block, and the T-shaped block is slidably connected to the T-shaped slot.

[0013] The beneficial effects of the utility model are:

[0014] 1. Turn the turntable clockwise to rotate the rotating rod in the driving cavity, and make the bevel gear 2 rotate synchronously with the rotating rod. Through the meshing of bevel gear 2 and bevel gear 1, the rotating screw rotates in the driving cavity, and the two sliders slide back to back. The sliding of the slider makes the limit rod move from the limit hole to the limit cavity, so that the bridge support rod can be removed from the bridge main rod, further reducing the space occupied by the ladder-type cable tray during transportation and placement, and facilitating the transportation and storage of the ladder-type cable tray.

[0015] 2. By twisting the adjusting disk, the adjusting screw rod moves into the clamping groove, thereby driving the upper clamping block to approach the lower clamping block. Under the action of the sliding groove and the sliding block, the upper clamping block slides steadily in the clamping groove to prevent the upper clamping block from shifting during the movement. As the upper clamping block continues to move, the upper clamping block continuously moves closer to the lower clamping block and clamps the cable between the two to fix the cable on the cable tray.
