Description

TECHNICAL FIELD

[0001] The present application relates to the field of cranes, in particular to a steel wire rope angle adjustable winding system. BACKGROUND

[0002] The steel wire rope angle refers to the angle of the steel wire rope to the drum or pulley when the steel wire rope winds in or out of the drum or pulley. GB / T 3811-2008 “Design Specification for Cranes” provides that when the steel wire rope winds in or out of the drum, the angle of the center line of the steel wire rope to the center line of the spiral groove on both sides should not be greater than 3.5°; the maximum angle of deflection of the steel wire rope when winding in or out of the pulley groove (i.e. the angle between the center line of the steel wire rope and the plane perpendicular to the pulley shaft) should not be greater than 5°.

[0003] However, in the actual working process of the crane, due to space limitations, the distance between the drum and the fixed pulley set weldment is close, and during the winding and unwinding of the steel wire rope, the steel wire rope angle is prone to be greater than 3.5°, which can easily cause serious wear of the steel wire rope, pulley groove and drum groove, and even cause the steel wire rope to come off the groove, thereby reducing the service life of the steel wire rope, pulley and drum, and reducing the safety and stability of the hoisting process.

[0013] By adopting the above technical scheme, the steel wire rope is wound on the two movable pulleys, and the height of the hook is adjusted through winding and unwinding of the steel wire rope, thereby realizing hoisting through the hook.
