The invention discloses a safety catch of a lifting hook, and relates to the technical field of safety catches. Comprising a supporting plate, a round rod arranged on the inner side of one end of the supporting plate, a torsional spring arranged on the outer side of the round rod, a protective shell arranged on the inner side of the supporting plate, a strong magnet arranged on one side of the end of the protective shell, an indicator lamp arranged on the inner side of the protective shell, an electric field intensity detector arranged on one side of the indicator lamp and a buzzer linearly connected with the electric field intensity detector. The battery is arranged at the lower position of the inner side of the protective shell, and the contact switch is arranged at the bottom of the battery. The hook safety catch has the beneficial effects that the hook safety catch is adsorbed on the hook by using magnetic attraction between the powerful magnet and the hook, so that the arm of force of the hook safety catch is increased, and the reliability is improved; meanwhile, when the steel wire rope is disassembled, the position of the safety catch can be fixed, and two hands of a worker are liberated; and the operation of a worker is better facilitated.
本发明公开了一种吊钩保险扣,涉及保险扣技术领域,包括,保险扣单元,包括支撑板、设置于支撑板一端内侧的圆杆、设置于圆杆外侧的扭簧、设置于支撑板内侧的防护壳、设置于防护壳端部一侧的强磁铁、设置于防护壳内侧的指示灯、设置于指示灯一侧的电场强度检测仪、与电场强度检测仪线性连接的蜂鸣器、设置于防护壳内侧靠下位置的电池,以及设置于电池底部的接触开关。本发明的有益效果为使用强力磁铁与吊钩之间的磁引力,使吊钩保险扣吸附在吊钩上,增加吊钩保险扣力臂,提升可靠性;同时,在拆卸钢丝绳时,可以将保险扣的位置固定,解放工作人员双手;更好地便于工作人员操作。
