摘　　要：文中针对放射性环境下人员无法接近操作抓具的问题,设计了一种可在无人员辅助的情况下,仅借助吊车通过周期性的上升和下落即可完成起吊及搬运重物操作的自动抓具。该抓具基于凸轮机构及连杆机构原理,实现了旋转抓钩结构的张开和闭合动作一体化集成。自动抓具的试验结果表明,该自动抓具可实现对重物多次抓取及释放,且过程顺畅无卡涩,验证了设计的正确性与可行性。所提出的结构及其设计方法可为其他同类产品提供参考。Considering that people can't get close to the gripper in radioactive environment,this paper puts forward a design of automatic gripper,which can lift and carry heavy objects by means of crane through periodic lifting and falling without the assistance of people.Based on the principle of cam mechanism and connecting rod mechanism,the gripper realizes the integration of opening and closing actions of rotating hook structure.The experimental results of the automatic gripper show that the automatic gripper can grasp and release heavy objects for many times,and the process is smooth and free from jamming,which verifies the correctness and feasibility of the design.The proposed structure and its design method can provide reference for other similar products.
