对目前吊装作业中吊钩防脱装置存在的问题进行了原因分析,针对原防脱装置的各种缺陷,研究设计了一种新型防脱装置。该装置结构简单,主要由弧形防脱限位挡板、配重球和双臂杆组成。该装置利用了重力和杠杆原理,操作方便、省力,装置损坏率低,防脱钩性能和强度较原来有大幅提高,达到了以人为本和安全生产的目的,具有良好的推广应用价值。
The reasons for the existing problems of the hook anti-drop device in the hoisting operation are analyzed. Aiming at the various defects of the original anti-drop device, a new type of anti-drop device is designed. The device has a simple structure and is mainly composed of an arc-shaped stopper, a weight ball and a double-arm rod. The device uses the principle of gravity and leverage, easy operation, labor-saving, low rate of device damage, anti-decoupling performance and strength than the original substantial increase to achieve the people-oriented and safety in production purposes, with good promotional value.
