The invention provides a safety lock for a hanging basket. The safety lock is structurally composed of a pulley, a lengthened swing arm, a shell, thickened torsion springs, lug plates, a lengthened lock cylinder, a rope feeding hole cap and a mounting seat. Positive pressure between the lock cylinder of the safety lock for the hanging basket and a safety steel wire rope is increased by increasingthe length of the lock cylinder, the number of the lug plates, the number of the torsion springs and the diameter of the torsion springs, the pattern structure of a groove part of the lock cylinder ischanged, the roughness between contact surfaces of the lock cylinder and the safety steel wire rope is increased, the mounting position and the structure of the swing arm are changed, and the use performance of the safety lock for the hanging basket is enhanced. Through the improvement on the safety lock for the hanging basket, the safety lock for the hanging basket can more quickly lock the safety steel wire rope when the working steel wire rope is suddenly broken, the rope locking distance of the safety lock for the hanging basket is reduced, the rope locking time is shortened, rope lockingis more stable, safety performance is stronger, and occurrence of high-altitude operation accidents is reduced.
本发明提供一种吊篮安全锁,其结构是由滑轮,加长摆臂,外壳,加粗扭簧,耳板,加长锁芯,进绳孔帽,安装座构成。通过增加锁芯长度,耳板数量,扭簧数量,扭簧直径,来增加吊篮安全锁锁芯和安全钢丝绳之间的正压力,改变锁芯沟槽部位的花纹结构,来增加锁芯和安全钢丝绳接触面之间的粗糙程度,改变摆臂安装位置和结构,来增强吊篮安全锁的使用性能。通过以上对吊篮安全锁的改进,可以使吊篮安全锁在工作钢丝绳突然断裂时,能够更快速地锁住安全钢丝绳,吊篮安全锁的锁绳距离减小,锁绳时间缩短,锁绳更稳固,安全性能更强,减少高空作业事故的发生。
