The output shaft of the reducer (4) and the input shaft of the reducer (4) are arranged in a 90-degree manner. A driving rope pulley (1) is fixed to the output shaft of the reducer. A climbing rope (13) is wound inside a rope groove of the driving rope pulley (1). The middle part of a warping brake rope-pressing pulley block (3) is positioned at the upper part at one side of the driving rope pulley (1) through a shaft pin, and rope-pressing pulleys (3-1,3-4) on two ends of the warping brake rope-pressing pulley block(3)tightly press the climbing rope in a warping manner. A reversing rope pulley (2) is positioned above the other side of the driving rope pulley (1). A rope groove in the reversing rope pulley (2) is matched with the rope groove in the driving rope pulley (1). The climbing rope is continuously wound between the rope groove of the driving rope pulley (1) and the rope groove of the reversing rope pulley (2) and is led out from the rope groove of the driving rope pulley (1). A speed control module (9) is positioned on the housing, and a signal output terminal of the speed control module (9) is connected with a signal input terminal of the electromagnetic brake direct current motor (11).
