The wire rope is pressed into the conical alloy sleeve by a press, and then the conical alloy sleeve with a tapered shape is matched with the taper of the inner hole of the cable segment body, and then the locking bolt is tightened to achieve the purpose of fixing the wire rope.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the conical inner hole of the wire rope alloy pressed conical joint device in the above-mentioned technology is large at the upper end and small at the lower end. During installation, the conical alloy sleeve can only be installed from the upper end of the conical inner hole into the conical inner hole. The conical alloy sleeve is fixed to the wire rope, so the entire wire rope needs to be passed through the conical inner hole during installation and disassembly, which has the defect of inconvenient installation and disassembly.
