It should be noted that when the axial limiting structure 64 is a limiting baffle, the diameter of the limiting baffle should be smaller than the inner diameter of the steel strand reel 9 and the tray 62, so as to ensure that the steel strand reel 9 and the tray 62 can be taken off the long shaft 61. Further, the brake device comprises a support plate 65, a screw rod 66 and a brake plate 67, wherein the support plate 65 is fixed on the long shaft 61 below the tray 62, the diameter of the support plate 65 is smaller than the inner diameter of the steel strand reel 9 and the tray 62, or the support plate 65 is connected with the long shaft 61 through bolts to facilitate disassembly and ensure that the steel strand reel 9 and the tray 62 can be taken off the long shaft 61; the tension plate 68 is arranged on the support plate 65, the screw rod 66 is threadedly connected with the tension plate 68, the force bearing support 69 is arranged on the support plate 65, and the brake plate 67 is a long strip-shaped sheet, one end of the brake plate 67 is rotationally connected with one end of the screw rod 66, and the other end is fixedly connected with the force bearing support 69 through the shaft sleeve 63.
