The invention discloses a safety interlocking device for a crane clamp hanger. The safety interlocking device comprises a first proximity detection unit, a second proximity detection unit and a controller, the first approaching detection unit is used for detecting whether a lifting arm of the clamp crane is close to a to-be-lifted coil stock or not; the second approaching detection unit is used for detecting whether a lifting hook of the crane clamp lifting appliance extends into the coil stock or not; the controller is used for enabling the crane clamp lifting appliance to stop the clamping action after the first approaching detection unit detects that the two lifting arms are both close to the to-be-lifted coil stock; the opening forbidding unit is used for forbidding the crane clamp lifting appliance from being opened after the second approaching detection unit detects that the lifting hook extends into the coil stock; and the lifting mechanism is used for allowing the crane clamp lifting appliance to ascend when the first approaching detection unit detects that the two lifting arms approach the coil stock to be lifted and the second approaching detection unit detects that the two lifting hooks extend into the coil stock.
本发明公开了一种行车夹钳吊具安全连锁装置,包括第一接近检测单元、第二接近检测单元和控制器;第一接近检测单元用于检测车夹钳吊的吊臂是否靠近待吊卷料;第二接近检测单元用于检测行车夹钳吊具的吊钩是否延伸入卷料内部;控制器用于在第一接近检测单元检测到两个吊臂均靠近待吊卷料后,使行车夹钳吊具停止夹紧动作;用于在第二接近检测单元检测到吊钩延伸入卷料内部后,使行车夹钳吊具禁止打开;用于在第一接近检测单元检测到两个吊臂均靠近待吊卷料且第二接近检测单元检测到两个吊钩均延伸入卷料内部时,使行车夹钳吊具允许上升。
