[0002] In the cable erection of various projects, the cable is usually wound on a cable reel, and the cable is erected by paying off the cable reel. In order to ensure the straightness of the cable during the pay-off process, the cable reel stand needs to be placed on the pay-off rack to pay off the cable. Most cable reels are heavy and cannot be moved and erected, and a hoisting machine is usually used to hoist the cable reel to erect the cable. The hoisting method is high in cost, and in some special locations, the hoisting machine cannot be positioned for operation. In some cases, the height of the erected cable needs to be slightly adjusted, which is inconvenient for the hoisting machine to operate, seriously affecting the progress of the cable erection.

The support seat includes a support frame and an upper support surface, and the upper support surface is provided with a first through hole. The nut block is placed on the first through hole, and the size of the nut block is larger than that of the first through hole. The support piece is provided with a second through hole for accommodating the wire rod. The threaded rod is fixedly connected with the bottom of the support piece, and the threaded rod is threadedly connected with the nut block and passes through the first through hole, and can be lifted by the hydraulic jack below. The cable pay-off rack can lift the cable reel by lifting the support piece of the cable pay-off rack when the diameter of the cable reel is large, thereby facilitating the pay-off.

[0004] The above device is inconvenient to quickly adjust the distance between the support frames when encountering cable reels of different widths, and the operator needs to move the support frames for adjustment. When the diameter of the pay-off reel is large, two people need to cooperate to adjust it, which is time-consuming and labor-intensive, increases manual labor, and affects the construction efficiency, so it needs to be improved.
