Device and method for erecting combined stay wire angle steel tower

The invention discloses an erecting device and method for erecting a combined type stay wire angle steel tower. The erecting method comprises the steps that segmented tower columns needing to be erected are detached and arranged in sequence; concrete is pre-poured at the mounting position to form an erecting base capable of placing the angle steel tower; the segmented tower columns are assembled in sequence, and cross arms are installed; stay wires are hung on the four outer side faces of the tower column, and the other ends of the stay wires are connected with the wire winding assembly; a worker starts the winding assembly to gradually tighten the stay wire, so that the mounted tower column is gradually pulled up by the stay wire to stand at a preset mounting position at the top of the erection base, and the worker shuts down the winding assembly; a worker fixes the angle steel tower and the erection base through a mounting flange and a bolt; and a maintenance ladder stand is installed on the outer side of t
