[0002] The storage barrels used in nuclear power plants are usually used to store radioactive materials, and workers are not allowed to approach directly. Even in the case of earthquakes, the grippers are required to effectively maintain the gripping state. Therefore, higher requirements are put forward for the grippers of storage barrels. Requirements, such as automatic grasping, high safety, high reliability, low failure rate, etc., most of the existing graspers for nuclear power plant storage barrels realize automatic grasping through electric drive or cylinder drive, complex structure, high cost, and failure high rate

The invention discloses an automatic gripper for a storage barrel, which comprises a suspension device, a gripping device and a self-locking device, which are connected through corresponding hinged shafts in a matching way. The automatic gripper has the advantages that: the structure is simple, and the manufacturing and the maintenance are convenient; the self-locking device is arranged, the alternate gripping and loosening of the storage barrel are carried out by the vertical movement of the automatic gripper, the operation is convenient, and the performance is reliable; in the event of a failure of the hinged shaft B, the self-locking device and the hinged shaft C, the automatic gripper can also be in a gripping state to ensure that the storage barrel does not fall off, and the safety is high; electrical, hydraulic or pneumatic drive are not needed, a mechanical mechanism needs only to actuate, so that the energy is saved, the environment is protected, and the cost is saved; and the key components of the self-locking device only have a guide cylinder, a spring, a sliding rod and a pushing sleeve, so that the failure rate is low, the versatility is strong, and the installation, maintenance, and replacement are convenient.
Description
technical field [0001] The invention relates to an automatic gripper for storage buckets, in particular to a storage bucket gripper capable of automatic gripping and self-locking. Background technique [0002] The storage barrels used in nuclear power plants are usually used to store radioactive materials, and workers are not allowed to approach directly. Even in the case of earthquakes, the grippers are required to effectively maintain the gripping state. Therefore, higher requirements are put forward for the grippers of storage barrels. Requirements, such as automatic grasping, high safety, high reliability, low failure rate, etc., most of the existing graspers for nuclear power plant storage barrels realize automatic grasping through electric drive or cylinder drive, complex structure, high cost, and failure High rate. Contents of the invention [0003] Aiming at the defects of the above-mentioned technical solutions, the technical problem solved by the present inventi...
