Locking is re-started to hook 325 so that hook 325 is kept open, grasping mechanism 32 capture object in the air when,
It avoids causing hook 325 to be detached from the object being crawled due to maloperation hook 325, to avoid the object of crawl from falling.More
Body it is as follows：
Again please continue to refer to Fig. 9 and Figure 10, in the present embodiment, first is equipped between installation set 326a and gripping head 321
Elastic component 326c, to provide the elastic force for making lock hook 326b be sticked in bayonet 325a, specifically, the first elastic component 326c is selected
Compressed spring, but not limited to this.Grasping mechanism 32 decline crawl object during, installation set 326a with it is to be captured
After isoelectric membrane, since grasping mechanism 32 will continue to decline, the first elastic component 326c can be compressed, and cushioning effect is played, meanwhile,
Installation set 326a can be due to being obstructed relative to 321 upward sliding of gripping head, to drive lock hook 326b to be detached from hook 325；
During grasping mechanism 32 rises and carries object, installation set 326a can be in the work of the elastic restoring force of the first elastic component 326c
With lower relative to 321 slide downward of gripping head, to drive lock hook 326b to engage with hook 325.In addition, in other implementations
In example, it can also be not provided with the first elastic component 326c between installation set 326a and gripping head 321, rise in grasping mechanism 32 and carry object
During part, installation set 326a can be under gravity and relative to 321 slide downward of gripping head, therefore is not limited.
As shown in Figure 10, specifically, the upper end of locking unlock rod 322 goes to upper and lower being set in installation part 323 of sliding.
Specifically, 323 inner wall of installation part is equipped with second sliding slot 323a along the central axis direction of locking unlock rod 322, locks unlock rod 322
It is equipped with the second locating part 323b that limitation locking unlock rod 322 is relatively rotated with installation part 323, the second locating part 323b slidings
Ground is set in second sliding slot 323a, and the rotary motion of installation part 323 can pass to locking unlock by the second locating part 323b
Bar 322.Wherein, in the present embodiment, the second locating part 323b selects screw, be conducive to it is cost-effective, and install it is simple and convenient,
Certainly, pulley or bolt etc. also can be selected in the second locating part 323b, is not limited.It is driven and is pacified by gripping head rotating mechanism 36
Piece installing 323 rotates, and makes installation part 323 that locking unlock rod 322 be driven to rotate, and locking unlock rod 322 drives gripping head 321 to revolve again
Turn, to which the fuel assembly 900 for making the hook 325 of gripping head 321 drive its crawl rotates, with the fuel assembly 900 to crawl
Orientation be adjusted；Certainly, before hook 325 captures fuel assembly 900, gripping head rotating mechanism 36 can also drive installation part
323 rotations are to adjust the orientation of hook 325 in gripping head 321.
As shown in Figure 10 to Figure 13, grasping mechanism 32 further includes the anti-rotation device for preventing installation part 323 from rotating
327, and anti-rotation device 327 be set to installation part 323 outside and can be to 323 locking of installation part.Anti-rotation device 327 includes
Pedestal 327a, the second sliding block 327b and the second elastic component 327c, the second sliding block 327b slidings are set in pedestal 327a, and second
The second elastic component 327c is equipped between sliding block 327b and pedestal 327a, the second sliding block 327b is under the action of the second elastic component 327c
Close to simultaneously locking installation part 323.Since when the orientation of the fuel assembly 900 to crawl is adjusted, installation part 323 needs to revolve
Turn, therefore anti-rotation device 327 further includes solution lock body 327d, solution lock body 327d can drive the second sliding block 327b to leave installation part 323,
Solve the bottom that lock body 327d is mounted on installation pedestal 31.In the present embodiment, the second sliding block 327b and the second elastic component 327c
Quantity is two, and two second sliding block 327b are oppositely disposed and there are a gap 327e, the sides of the second sliding block 327b among the two
Equipped with inclined-plane 3271b, when solution lock body 327d is inserted into gap 327e, solution lock body 327d squeezes two second sliding block 327b so that two second
The inclined-plane 3271b of sliding block 327b leaves installation part 323；When solution lock body 327d exits gap 327e, two second sliding block 327b difference
Close to simultaneously locking installation part 323 under the action of the second elastic component 327c.Certainly, in other embodiments, the second sliding block 327b
And second the quantity of elastic component 327c be alternatively one, be not limited.
In conjunction with Fig. 9 to Figure 13, the specific operation principle that grasping mechanism 32 captured and put down fuel assembly 900 is as follows：
When gripping head 321 is inserted into the crawl interface position of fuel assembly 900, hook 325 is still in contraction state；Work as lock
Determine device 326 installation set 326a contacted with fuel assembly 900 after, grasping mechanism 32 continues to decline, the first elastic component 326c quilts
Compression, installation set 326a is due to being obstructed relative to 321 upward sliding of gripping head, one of lock hook 326b and hook 325
Bayonet 325a is detached from, to 325 release the lock of hook；Locking unlock driving mechanism driving locking unlock rod 322 declines, locking unlock
Bar 322 supports hook 325 so that the lower end rotating opening of hook 325, to make hook 325 capture fuel assembly 900；Then,
Lifting spindle driving mechanism driving spindle 331 moves up so that gripping head 321 rises, and installation set 326a is no longer obstructed, the
Under the elastic restoring force effect of one elastic component 326c, installation set 326a glides so that another of lock hook 326b and hook 325
Bayonet 325a engagings, i.e., lock hook 326b again locks hook 325, prevents during fuel assembly 900 shifts
It locks unlock rod 322 and rises contraction hook 325, and then prevent fuel assembly 900 from falling, avoid causing safety accident.It is needing
When being adjusted to the orientation of fuel assembly 900, lifting spindle driving mechanism driving spindle 331 moves up, and main shaft 331 drives
Babinet 324 moves up, and to drive grasping mechanism 32 to rise, makes the swivel head 361 and gripper of gripping head rotating mechanism 36
The installation part 323 of structure 32 docks, while solving the gap that lock body 327d is inserted between two second sliding block 327b of anti-rotation device 327
In 327e, solution lock body 327d squeezes two second sliding block 327b so that the inclined-plane 3271b of two second sliding block 327b leaves installation part
323, gripping head rotating mechanism 36 drives installation part 323 to rotate, to be adjusted to the orientation of fuel assembly 900.Orientation tune
After the completion of whole, solution lock body 327d exits gap 327e, and two second sliding block 327b are leaned under the action of the second elastic component 327c respectively
Close and locking installation part 323.
