The technical solution adopted by the present invention to solve the above-mentioned technical problems is that a multi-layer elevating cable shelf includes two guide rails and a plurality of linearly arranged brackets arranged between the two guide rails. There is a crane, which is provided with a cable tray bracket, and the cable tray bracket is suspended on the bracket lifting and translation mechanism set on the crane; the bracket includes a base and two columns fixed on the base, two At least one side of the column is provided with several groups of cantilevers in pairs, one end of the cantilever is movably connected to the column, and the other end of the cantilever is provided with a cable tray positioning slot. When the multi-layer lift cable shelf is working, the cable tray is placed On the cable reel bracket, the crane passes the bracket lifting and translation mechanism and combines the driving to place the cable reel bracket above a set of cantilevers and hangs it in the cable reel positioning groove of the cantilever through the transverse shaft pierced on the cable reel. The multi-layer elevating cable shelf of the present invention includes a plurality of supports with several layers of cantilever, the driving can walk along the guide rail, the height of the driving is greater than the height of the support, and a cable reel bracket for transporting the cable reel is arranged on the driving. There is a bracket lifting and translation mechanism for the lifting and translation of the cable reel bracket, wherein the translation mechanism can translate the cable reel bracket to the outside of the support, so as to facilitate the hoisting of the cable reel. When the cable reel needs to be stored, the cable reel is placed on the cable reel bracket, and the cable reel bracket and the cable reel are moved together to the working range of the crane by a forklift, and are moved by the travel of the truck and the translation mechanism of the bracket on the truck. The lifting mechanism of the bracket is located above the cable tray bracket, and the cable tray bracket is connected with the bracket lifting mechanism through a wire rope and a hook. The position of the cantilever is then lowered, so that the horizontal axis in the middle of the cable reel (a steel pipe that passes through the cable reel and is longer than the height of the cable reel) is placed in the cable reel positioning groove of the cantilever, and the three-dimensional palletizing of the cable reel is completed; When it is necessary to take out the cable reel, it is first necessary to move the crane carrying the cable reel bracket to the obliquely above the cable reel, then move the cable reel bracket to the bottom of the cable reel, and then raise it to a certain height so that the horizontal shaft on the cable reel is separated from the cantilever , and then drive away from the support and drop to the ground, the cable reel bracket is separated from the driving hook, and the access of the cable reel is completed.
