Abstract
The utility model discloses a hoisting pulley comprising a pulley bracket, a pulley bearing, a pulley, a lifting hook, a small lifting ring, a lifting hook tongue piece and a pin roller, wherein the pulley is arranged in the middle of the pulley bracket through the pulley bearing; the lifting hook is arranged on the top of the pulley bracket; the small lifting ring is arranged at the bottom of the pulley bracket; the lifting hook tongue piece is hinged at the opening of the lifting hook through a shaft pin; a reset spring is arranged between the lifting hook tongue piece and the lifting hook; and the pin roller is arranged on the top of the inner side of the lifting hook in a rolling manner. The hoisting pulley has the advantages that the lifting hook tongue piece and the reset spring are arranged at the opening of the lifting hook, so that the hook opening can be timely closed after a rope is hung up and the rope is incapable of dropping in the construction process; in the meantime, the rolling pin roller is arranged inside the top of the lifting hook, so that the friction between the lifting hook and the rope is avoided; and the lifting hook and the pulley bracket connected in a manner of capable of rotating by 360 DEG, so that the pulley can meet the construction requirements of various situations.
Description
Technical field
The utility model relates to a kind of gin wheel.
Background technology
Gin wheel is a kind of important lifting device, and it is simple in structure and easy to use, in power construction, is widely used.There is following shortcoming in gin wheel of the prior art: 1. suspension hook mouth does not have catch, in use easily comes off, and exists great potential safety hazard in work progress; 2. serious with rope friction in suspension hook use procedure; 3. ineffective words of pulley rolling; In view of above defect, be badly in need of a kind of rational in infrastructure and gin wheel that safety performance is high.
Summary of the invention
