Problems solved by technology

[0009] In the traditional sequential rope-threading method, the starting end and the end of the steel wire rope 1 are distributed on both sides of the pulley shaft. Due to the frictional resistance between the steel wire rope 1 and the pulley, the force on the starting end and the end of the steel wire rope 1 will be uneven, and the steel wire rope 1 The starting end and the end are distributed on both sides of the pulley shaft 6, and the force transmitted to the two ends of the pulley sh

Abstract

The invention discloses a wire-rope/pulley component which comprises a first pulley block, a second pulley block and a wire rope passing through the first and the second pulley blocks, wherein the wire rope passes alternately through individual pulleys in the first and the second pulley blocks, and the head end and the tail end of the wire rope are positioned on the same side of a pulley shaft. The interference between the wire rope of the wire-rope/pulley component and a lifting hook side plate is eliminated, so that the service life of the wire rope is increased and thus the safety and economy are significantly improved. The invention also discloses a crane provided with the wire-rope/pulley component.

Description

Technical field [0001] The invention relates to the technical field of engineering machinery, in particular to the wire rope pulley assembly of a crane. The invention also relates to a crane provided with the wire rope pulley assembly. Background technique [0002] The hoisting mechanism is one of the main actuators of the crane to realize the lifting movement of the heavy objects. The hoisting mechanism is usually composed of a reel, a reducer, a brake, a clutch, a wire rope pulley block and a hoisting hook, etc., during the working process of the crane In this, the power is transmitted from the prime mover to the wire rope and lifting hook through the lifting mechanism, and the function of vertical lifting and horizontal transport of heavy objects within a certain range is realized by changing the amplitude and elevation of the boom. [0003] With the development of large-tonnage cranes, their lifting capacity is getting stronger and stronger, and the load on the lifting hook is...
