Electromagnetic grabbing tool for nuclear power plant

Abstract

The invention discloses an electromagnetic gripper used in nuclear power plants. The electromagnetic gripper includes a gripper body, an electromagnetic drive mechanism, a stretching mechanism and a claw hook. An electromagnetic drive mechanism is arranged in the gripper body. The lower part of the tool body is movably connected with several claw hooks. The electromagnetic drive mechanism is connected with the stretching mechanism to drive the stretching mechanism to move up and down. The electromagnetic drive mechanism moves up and down through the stretching mechanism. Realize the opening and closing of the claw hook. The invention realizes the opening and closing of the claw hook by driving the up and down movement of the stretching mechanism through the electromagnetic drive mechanism, which can realize the grasping and safe hoisting of the grasped object. Maintain the grasping state of the grasped object and effectively avoid accidental decoupling accidents. The grasper can be used to operate similar equipment in high-temperature gas-cooled reactor nuclear power plants and other types of nuclear power plant spent fuel storage facilities, and can also be used for grasping various types of equipment in general industries. Pick up and hoist.

Description

technical field [0001] The invention belongs to the technical field of grippers, in particular to an electromagnetic gripper used in nuclear power plants. Background technique [0002] As we all know, the gripper is a tool for grabbing and hoisting various types of equipment. The existing grippers are electromagnetic and pneumatic. . Because the object is grasped by external force, once the external force disappears accidentally, the object will fall, which endangers the safety of the operator and the hoisted object. [0003] In dangerous environments such as nuclear and high temperature, the reliability of the gripper is required to be higher. Under various working conditions, the safety of manhole cover hoisting must be ensured. When grasping nuclear material, once the external force disappears, the gripper will lose its effectiveness, causing the nuclear material to fall off. The resulting nuclear radiation will not only affect the work progress, but also affect the saf...

Problems solved by technology

When grasping nuclear material, once the external force disappears, the gripper will lose its effectiveness, causing the nuclear material to fall off. The resulting nuclear radiation will not only affect the work progress, but also affect the safety of the surrounding environment

[0004] The existing grippers cannot avoid accidental decoupling accidents, and cannot adapt to special environments such as nuclear and high temperature
