The invention belongs to the field of ships and maritime work, and particularly relates to a simple chain ring overload protection device which comprises a chain ring, the chain ring comprises two arc-shaped parts, two first straight body connecting parts and a straight body part, and the two ends of the straight body part are integrally formed with the two arc-shaped parts respectively. One end of each arc-shaped part is integrally formed with the corresponding first straight body connecting part, an overload protection part is arranged between the two first straight body connecting parts, the chain ring is simple and practical, the needed residual strength and sectional area can be calculated according to needs, and then the purpose of overload protection can be achieved by machining the chain ring to the corresponding sectional area. And on the other hand, when the non-welded chain ring serves as the balance weight chain, compared with a common balance weight chain, the processes of flash welding and weld joint nondestructive testing are omitted, the cost is greatly reduced, and the practicability is remarkably improved.
本发明属于船舶和海工领域,尤其是一种简易的链环过载保护装置,包括链环,所述链环包括两个弧形部、两个第一直体连接部和一个直体部,所述直体部的两端分别与两个弧形部一体成型,两个弧形部的一端分别与第一直体连接部一体成型,两个第一直体连接部之间设置有过载保护部,本发明简单实用,可以根据需要计算出所需的剩余强度和截面积,然后将链环加工到对应截面积即可达到过载保护的用途。另一方面,不焊接的链环在作为配重链时,相对于普通配重链减少了闪光焊接和焊缝无损检测的过程,成本大幅降低,实用性显著提高。
