Abstract
The invention relates to a pulley block structure, and in particular relates to a pulley block structure for a steel wire rope. The pulley block structure for the steel wire rope comprises a pulley shaft, an auxiliary roller, a pulley and a pulley seat, wherein the holes of the pulley shaft and the auxiliary roller are arranged on the pulley seat, and the pulley seat is of two side plates; the two side plates have the same structure and are symmetrically arranged, and the pulley shaft and the auxiliary roller are arranged between the two side plates; and the pulley is connected onto the pulley shaft, and a steel wire rope slot is arranged on the pulley. According to the pulley block structure for the steel wire rope provided by the invention, the steel wire rope is driven more stably, thereby ensuring the stable operation of a driving piece.
Description
