Hoisting drum steel wire end fixing device and workover rig

The utility model relates to an application of a winch system of a petroleum workover rig, namely a hoisting drum steel wire end fixing device and a workover rig. A rope end of which the diameter is larger than a rope diameter is arranged at one end of a steel wire, a rope end hole which allows the rope end to be inserted is formed in a wallboard corresponding to one side of a roller, and a rope groove notch for clamping a rope is communicated with the hole side of the rope end hole. When the steel rope is installed or replaced, the rope end is needed to be inserted along the rope end hole, the rope body is downwards clamped to the bottom along the rope groove notch, the rope groove notch blocks the rope end without being loosened, so that the rope is rapidly fixed. The hoisting drum steel wire end fixing device is convenient to operate, low in labor intensity of workers, and short in time of replacing the steel rope, brings the convenience for rapidly replacing the hoisting steel rope outdoors in an energy-s
