Abstract

The invention discloses a multi-layer helix rope winding groove coiling barrel, which comprises a coiling barrel (1), a helix rope groove (2), a steel wire rope (13) ad a coiling barrel side plate (14), wherein two ends of the coiling barrel (1) are used as the installation interfaces (6); a rope through hole (7) is formed in the coiling barrel side plate (14); a rope climbing block (3) is arranged at the tail end of the helix rope groove (2); a wedge-shaped block (4) is arranged at the beginning end of the steel wire rope (13); the wrap angle alpha of the rope climbing block (3) ranges from 0 degree to 270 degrees; the height of the rope climbing block (3) is increased from 2mm to the diameter of the steel wire rope (13) gradually; the width of the rope climbing block (3) is reduced from being equal to the diameter of the steel wire rope (13) to the 1 / 4 of the diameter of the steel wire rope (13); the wrap angle alpha 2 of the wedge-shape block (4) ranges from 0 degree to 320 degrees; the height of the wedge-shape block (4) is equal to the diameter of the steel wire rope (13); and the width of the wedge-shape block (4) is reduced from being equal to the diameter of the steel wire rope (13) to the 1 / 9 of the diameter of the steel wire rope (13).

Description

technical field [0001] The invention relates to a hoisting mechanism of a crane, and more specifically relates to a multi-layer winding spiral rope groove reel, which belongs to the field of construction machinery pile machinery equipment. Background technique [0002] At present, in the construction machinery industry, there are two types of drums used in the hoisting mechanism of cranes, one is a spiral rope groove drum, and the other is a double broken line rope groove drum. The double-fold rope groove drum can effectively avoid the phenomenon of rope disorder when winding the wire rope in multiple layers, achieve smooth and neat winding, and effectively reduce the friction and wear of the wire rope. However, its structure is relatively complex, and it requires high dimensional accuracy such as rope grooves, casting or processing is difficult, and the cost of purchasing and using is high; moreover, the requirements for the angle of the wire rope on the drum are relatively...
