Description

Technical Field

[0001] The present invention belongs to the technical field of precise docking of sling locks, and specifically relates to a precise docking device for sling locks of port terminal containers. Background Art

[0002] Port terminal containers are an important part of international trade and logistics transportation. A container is a standardized cargo transport box used to facilitate the transfer of goods between sea, land, and air transportation. Containers are usually made of steel or aluminum and have a strong structure to protect goods from the external environment. During the use of port terminal containers, slings are needed to lift and transfer the containers. The sling lock is a key component connecting the container and the sling, usually with high strength and high wear resistance to withstand heavy loads and frequent use. The precise docking device for sling locks of port terminal containers is a key equipment to ensure the safety and efficiency of containers during lifting and transportation.

[0003] The existing precise docking devices for sling locks of port terminal containers have certain drawbacks when in use. When the existing precise docking devices for sling locks of port terminal containers are in use, usually, the lifting equipment is used to control the container sling to move above the container, and then other workers cooperate to control the container sling to slowly move directly above the container, and then the workers control the sling lock to align with the container, which increases the labor intensity of the workers, reduces the fixing efficiency between the container sling lock and the container, and reduces the lifting efficiency of the container, and cannot meet the needs of people.

[0037] In summary, move the main body 1 of the container spreader above the container, control the main body 1 of the container spreader to move downward, so that the flexible moving wheels 22 roll on the upper end surface of the container, horizontally and longitudinally move the main body 1 of the container spreader, so that the flexible moving wheels 22 are separated from the container. Under the action of gravity, the first connecting plate 14 moves in the first connecting member 13, the first connecting rod 16 moves in the first connecting plate 14, the first buffer spring 17 expands and contracts, so that the two groups of first connecting seats 12 move to the front and rear sides of the container respectively. Start the limit hydraulic cylinder 3 to drive the limit seat 6 to move, so that the limit seat 6 drives the first connecting seat 12 to move. The first connecting seat 12 drives the first connecting plate 14 to move through the first connecting member 13, and the first connecting plate 14 drives the first auxiliary seat 19 to move through the reinforcing block 18, so that several groups of first auxiliary blocks 20 are attached to the front and rear side surfaces of the container, so that the lock head of the main body 1 of the container spreader is aligned with the lock of the container on the front and rear sides. Horizontally and transversely move the main body 1 of the container spreader, start the first auxiliary motor 34 to drive the first auxiliary block 20 to rotate, so that the first auxiliary block 20 assists the main body 1 of the container spreader to move and align the container. Start the second auxiliary motor 35 to drive the second auxiliary block 33 to rotate, so that the second auxiliary block 33 assists the main body 1 of the container spreader to horizontally and transversely move on the upper end surface of the container. When the second auxiliary block 33 is separated from the container, under the action of gravity, the second connecting plate 24 moves downward inside the second connecting seat 23, so that the second connecting plate 24 drives the first connecting block 25 to move, so that the first connecting block 25 moves on the second connecting rod 26, so that the second buffer spring 27 expands and contracts, and the second auxiliary blocks 33 on the left and right sides are aligned with the two sides of the container, so that the lock head of the main body 1 of the container spreader is accurately aligned with the lock of the container. Move the main body 1 of the container spreader downward so that the lock head and the lock are butted and locked.

The two rotating connecting rods 10 and the two first rotating seats 9 cooperate to use a first connecting member 13 or a second connecting seat 23 to perform reciprocating movement.

[0041] In summary, when the first auxiliary block 20 or the second auxiliary block 33 moves on the concave and convex outer surfaces of the container, when moving from the concave surface to the convex surface, the first auxiliary block 20 or the second auxiliary block 33 moves outward, causing the first auxiliary seat 19 and the second auxiliary seat 32 to move outward. The first auxiliary seat 19 causes the first connecting plate 14, the first connecting member 13, and the first connecting seat 12 to control the limiting seat 6 to move outward. The second auxiliary seat 32 causes the second connecting member 28, the second connecting plate 24, and the second connecting seat 23 to control the limiting seat 6 to move outward, so that the limiting seat 6 drives the rotating connecting rod 10 to rotate through the first rotating seat 9, causing the rotating structural member to rotate and fold, and causing the limiting plate 5 to control the limiting spring 7 to move on the limiting rod 8. Similarly, when moving from the convex surface to the concave surface, the first auxiliary block 20 or the second auxiliary block 33 moves inward, so that the limiting seat 6 drives the rotating connecting rod 10 to rotate through the first rotating seat 9, causing the rotating structural member to rotate and fold, and causing the limiting plate 5 to control the limiting spring 7 to move on the limiting rod 8, cooperating with the damping member 4 to play a role in vibration reduction and extending the service life of the limiting structure.
