The invention relates to a high-altitude immediate-dismounting derrick device. A U-shaped hoop and a vertical bracket are fixed on the neck of a hanger, wherein an arched connecting rod and an arched connecting rod connecting plate are connected to the lower end of the vertical bracket; the lower end of the arched connecting rod connecting plate is spliced with a horizontal insertion pin, the left end of the horizontal insertion pin is hinged with a short connecting rod, the left end of the short connecting rod is hinged with the upper part of a short arm of an L-shaped swinging rod, a swinging rod traction rope is connected to the long arm end head of the L-shaped swinging rod, the corner of the L-shaped swinging rod is hinged at the left end of the L-shaped long rod; the long arm of the L-shaped long rod extends out rightwards, the short arm of the L-shaped long rod is connected to the right end and hinged to the lower part of a Y-shaped connecting rod; a T-shaped rod sleeve is welded on the middle part of the long arm of the L-shaped long rod, a T-shaped rod is spliced in the T-shaped rod sleeve, the lower end head of the T-shaped rod is connected with the lower end head of the swinging rod traction rope; a horizontal rod is welded on the top of the T-shaped top rod, a long connecting rod is hinged on the middle part of the horizontal rod, the lower end of the long connecting rod is hinged with the lower end head of the Y-shaped connecting rod, and a Y-shaped fork opening is formed in the upper end head of the Y-shaped connecting rod. The high-altitude immediate-dismounting derrick device can be used for suspending and lifting a steel wire rope without the need of climbing the derrick.
