Embodiment Construction

[0024] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0025] The device is installed in a strictly sealed room 108. The driving mechanism is preferably three independent driving mechanisms, which are respectively the guide column driving mechanism 1, the gripper driving mechanism 2a, and the rack driving mechanism 2b. The transmission shaft is a rack horizontal transmission. Shaft 6, gripper horizontal drive shaft 7. The transfer machine is mainly composed of guide column driving mechanism 1, gripper, rack driving mechanism 2a, 2b, intermediate reducer 3, rotating column 4, connecting frame 5, rack horizontal transmission shaft 6, gripper horizontal transmission shaft 7, guide Column 8, rack 30, gripper 59 etc. are formed. The grip driving mechanism 2 a is used to drive the grip, and the rack driving mechanism 2 b is used to drive the rack 30 . Figure 7 All the components below the bumper 40 tha...

Abstract

The invention discloses a fuel assembly transfer machine, comprising a drive mechanism, an intermediate reducer (3), a rotating column (4), a connecting frame (5), a transmission shaft, a guide column (8), a rack (30), and a handle etc., it is characterized in that the driving mechanism is connected with the rotating column (4) through the intermediate accelerator (3), the rotating column (4) is connected into one body through the connecting frame (5), the transmission shaft and the guiding column (8), and the guiding column (8 ) is provided with a rack (30) and a gripper. The device can be self-locked, has high positioning accuracy, good reliability, easy maintenance and is suitable for long-distance operation.

Description

technical field [0001] The invention relates to the technical field of reactor engineering, in particular to a fuel assembly transfer machine. Background technique [0002] In the reactor, there are many operations on fresh and spent fuel, and most of the operating environments have strong radioactivity, and some components are far away from the operating platform, and the length of the general fuel gripper cannot meet the distance requirements. Some currently known grippers have complex structures and need to introduce counterweights to balance to complete the gripping operation. Contents of the invention [0003] The invention overcomes the deficiencies in the prior art, and provides a fuel assembly transfer machine capable of self-locking, good reliability and long-distance operation. [0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: [0005] A fuel assembly transfer machine, includ...
