[0024] A connecting seat 409 is installed on the structural surface of the clamping frame 401 close to the sliding groove 402; a structural cavity 410 is opened at the bottom of the connecting seat 409; a moving groove 411 is opened on one side surface of the inner wall of the structural cavity 410; a bidirectional lead screw 412 is installed inside the moving groove 411; moving blocks 413 are installed on the outer sections of both ends of the bidirectional lead screw 412; a clamping plate 414 is fixedly connected to the connecting end of the moving block 413; the vertical cross-section of the clamping block 407 is triangular; when the top end face of the clamping block 407 contacts the top end face of the inner wall of the structural cavity 410, the body of the connecting seat 409 contacts the connecting plate 406; inserting rods 415 are fixedly connected to the opposite structural surfaces of the clamping plate 414; after the clamping block 407 is completely inserted into the structural cavity 410, the movement track of the inserting rod 415 is inserted into the insertion hole 408; a driving mechanism 416 is installed on one end structural surface of the connecting seat 409; the output shaft connecting end of the driving mechanism 416 is connected to the end of the bidirectional lead screw 412; a support rod 417 is installed outside the telescopic mechanism 404; the top end of the support rod 417 is connected to the block body of the sliding block 403;

[0025] During operation, in the process of shipbuilding, hoisting equipment is required to lift the plates to meet the processing or assembly of the plates. During the use of the existing plate hoisting device, the plates will shake or rotate, causing the entire spreader to shake, which not only affects the safety of the spreader operation, but also causes damage to the plates themselves. This application acts through a limiting device. The clamping mechanism 6 on the clamping frame 401 is used to clamp and fix the plates. The telescopic mechanism 404 operates, and the telescopic rod 405 drives the connecting plate 406 and the clamping block 407 to approach the connecting seat 409, applying a pushing force to the sliding block 403. The sliding block 403 drives the clamping block 407 to enter the interior of the structural cavity 410 along the sliding groove 402. The driving mechanism 416 is started, and the bidirectional lead screw 412 in the moving groove 411 is moved. The moving block 413 drives the clamping plate 414 and the insertion rod 415 to move towards each other, so that the insertion rod 415 is inserted into the insertion hole 408. When the plate is placed, the clamping frame 401 gradually moves downward. Under the cooperation of the sliding groove 402 and the sliding block 403, the connecting plate 406 moves downward accordingly, causing the clamping frame 401 to move in the vertical direction, avoiding the shaking or rotation of the plate during hoisting.

[0026] Please refer to Figures 2-3 As shown, a bottom plate 501 is provided at the bottom of the connecting plate 406; a fixed cylinder 502 is fixedly connected to the top of the bottom plate 501; a telescopic cavity 503 is provided inside the fixed cylinder 502; a fixed rod 504 is provided inside the telescopic cavity 503; the top of the fixed rod 504 is connected to the plate body of the connecting plate 406; a guide plate 506 is installed on the side of the bottom plate of the clamping frame 401 through a pin shaft; a spring 505 is sleeved and installed outside the cross section of the fixed rod 504; the bottom end of the spring 505 is connected to the bottom end surface of the telescopic cavity 503; the top end of the spring 505 is connected to the rod body of the fixed rod 504;

[0027] During operation, as the clamping frame 401 gradually descends, the bottom plate 501 contacts the ground, and the clamping frame 401 and the connecting plate 406 continue to move downward. The fixed rod 504 moves downward along the telescopic cavity 503, and the spring 505 is compressed by force and generates a reaction force, reducing the impact force of the plate moving downward. With the cooperation of the guide plate 506, it facilitates the subsequent plate placement operation.

[0028] Working principle: During the shipbuilding process, lifting equipment is required to lift the plates to meet the processing or assembly requirements of the plates. During the operation of the existing plate lifting device, the plates will shake or rotate, causing the entire lifting tool to shake. This not only affects the safety of the lifting tool operation but also causes damage to the plates themselves. In this application, the limiting device is used. The clamping mechanism 6 on the clamping frame 401 is used to clamp and fix the plates. The telescopic mechanism 404 operates, and the telescopic rod 405 drives the connecting plate 406 and the clamping block 407 to approach the connecting seat 409, applying a pushing force to the sliding block 403. The sliding block 403 drives the clamping block 407 to enter the interior of the structure cavity 410 along the sliding groove 402. The driving mechanism 416 is started, and the bidirectional lead screw 412 in the moving groove 411 is moved. The moving block 413 drives the clamping plate 414 and the insertion rod 415 to move towards each other, causing the insertion rod 415 to insert into the insertion hole 408. When the plate is placed, the clamping frame 401 gradually moves downward. Under the cooperation of the sliding groove 402 and the sliding block 403, the connecting plate 406 moves downward accordingly, causing the clamping frame 401 to move in the vertical direction, preventing the plate from shaking or rotating during the lifting process, ensuring the safety of the operation and also guaranteeing the integrity of the plate itself. When the bottom plate 501 contacts the ground, the clamping frame 401 and the connecting plate 406 continue to move downward, and the fixing rod 504 moves downward along the telescopic cavity 503. The spring 505 is compressed under force and generates a reaction force, reducing the impact force of the plate moving downward. With the cooperation of the guiding plate 506, it facilitates the subsequent plate placement operation.
