Triggering unhooking device for large-scale equipment anti-falling test

The utility model belongs to the technical field of mechanical engineering, and particularly relates to a triggering unhooking device for an anti-falling test of large equipment. The device specifically comprises a hanging arm, a lower hook, a locking arm, a rotating arm and a trigger, the middle section of the rotating arm is hinged to the hanging arm; a locking hook is arranged at one end of therotating arm, and a locking arm is hinged to the other end; a roller is arranged at the other end of the locking arm; a lug plate is arranged on the hanging arm, and the trigger plate machine is hinged to the lug plate; a groove is formed in the upper end face of the side, close to the hanging arm, of the trigger trigger. When a heavy object is hung, locking is firm, and safety accidents such asfalling of the heavy object are avoided; and when unhooking is carried out, the contact trigger is pulled, and safety and rapidness are achieved. 本实用新型属于机械工程技术领域，具体涉及一种大型设备防坠试验触发脱钩装置。具体包括挂臂、下挂钩、锁止臂、转动臂和触发扳机；所述转动臂的中段与所述挂臂铰接；所述转
