Abstract
The utility model relates to a slant pulley lifting hook group of a crane. The slant pulley lifting hook group comprises two yoke plates, a pulley group mounted between the two yoke plates, lifting hook cross beams and lifting hooks mounted on the lifting hook cross beams, wherein the pulley group comprises two pulley shafts mounted between the two yoke plates; high-strength nylon pulleys are uniformly arranged on the pulley shafts; the two pulley shafts are symmetric about the central line between the two pulley shafts; extending lines of the two pulley shafts are crossed to form an acute angle. According to the slant pulley lifting hook group, the wear of a steel wire rope is relieved and the service life of the steel wire rope is prolonged.
Description
Technical field
The utility model relates to a kind of crane facility, is specifically related to a kind of crane inclined pulley suspension hook group.
Background technology
Tradition suspension hook group comprises pulley sheet, yoke plate, suspension hook, lifting beam with hook, hook nut, axle, axle sleeve, circular nut and pulley shield etc., the suspension hook group of this structure is because horizontal displacement is larger, big elevating height steel rope is easily staggered, cause steel rope abrasion comparatively fast to be scrapped in advance, bearing often needs lubricated, operating noise is large, from great troublesome maintenance, is not suitable for especially the production in light industry place that precision prescribed is high, production environment cleanliness level high noisy is little.
Utility model content
The utility model, for the problem that above-mentioned traditional suspension hook group is not durable and noise is large, provides a kind of crane inclined pulley suspension hook group, and it is lightweight, and noise is low, long service life.
For achieving the above object, the technical scheme that the utility model is taked is:
A kind of crane inclined pulley suspension hook group, comprise two yoke plates, be arranged on assembly pulley and the lifting beam with hook between two yoke plates and be arranged on the suspension hook on lifting beam with hook, described assembly pulley comprises two sheave shafts that are arranged between two yoke plates, on sheave shaft, be evenly provided with nylon pulley, two sheave shafts are symmetrical about the line of centers between described two sheave shafts, and described two sheave shaft extended lines intersect in an acute angle.
On described lifting beam with hook, thrust baring is installed, suspension hook upper end is provided with hook nut through after thrust baring.
It is 16 ° that described two sheave shaft extended lines intersect in an acute angle.
Described two sheave shaft outer ends are provided with fixed type bearing lid.
The utility model assembly pulley is provided with sheave shaft, on sheave shaft, be evenly provided with nylon pulley, described two sheave shafts have angle, wirerope-winding on nylon pulley time, has reduced the angle between steel rope and high-strength nylon pulley, has alleviated steel rope abrasion, increase steel rope and assembly pulley service life, reduce owner's use cost, avoided interlocking between steel rope simultaneously, extended service life of steel wire rope.
