The invention discloses a pulley with an anti-swing function for a lifting appliance of a hoisting machine. The phenomenon that the lifting appliance swings in the hoisting process of the hoisting machine is avoided. When a trolley does not have a lifting instruction, a brake shoe in the pulley is in contact with a brake drum, so that rotation of the pulley is limited, two steel wire ropes consume energy due to damping of the pulley, and the purpose of eliminating swing is achieved. According to the novel pulley for the lifting appliance of the hoisting machine, the swinging phenomenon in the hoisting process can be well eliminated, the operation efficiency is greatly improved, and meanwhile, the position precision of the lifting appliance of the hoisting machine during unloading can be better guaranteed.
本发明针对起重机械吊运过程中的吊具摆动现象,设计了一种具有防摇功能的起重机械吊具用滑轮。在小车无起升指令时,让滑轮内部的制动蹄接触制动鼓,从而限制滑轮的转动,两根钢丝绳会因为滑轮的阻尼消耗能量,达到消除摆动的目的。本发明设计的新型起重机械吊具用滑轮,可以很好地消除其吊运过程的摆动现象,大幅提高作业的效率,同时可以更好的保证卸载时起重机械吊具的位置精度。
