Description

Technical Field

[0001] This invention relates to the field of container hoisting technology, specifically to a port container hoisting device with anti-slip function. Background Technology

[0002] Container lifting is primarily carried out using spreader equipment. The spreader is placed on the container, and the four locking lugs at the bottom of the spreader are aligned with the corner fittings at the four corners of the container. The four lugs are then inserted into the corner fittings. Steel cables are connected via lifting rings at the four corners of the spreader, and finally, shackles and a crane are connected to perform the lifting operation. Alternatively, a remote control system for the port container crane can be directly integrated with the lifting device, allowing remote command control to complete the lifting, transfer, and lowering of containers.

[0003] Chinese invention patent application CN202410752844.5 discloses a container spreader for detecting the orientation of container doors. When lifting the container, the lock head on the spreader body is first aligned with the corner casting, and then the lock head is inserted into the corner casting to achieve docking between the spreader and the container.

[0004] However, in the aforementioned application, the rotation of the lock head relies entirely on the cylinder as the driving component. When the cylinder is damaged, the entire locking function will be immediately paralyzed, the lock head cannot rotate, and the container corner fittings cannot be disengaged or locked. If the container lifting work is to continue at this time, the damaged cylinder needs to be repaired or replaced immediately, the entire lifting equipment will stop, and the lifting efficiency of the container will be affected.

[0027] Working principle: When in use, four steel wire ropes are connected to the top of the lifting frame 1, and then the four steel wire ropes are connected to the hook in the crane. The crane moves the lifting frame 1 to the top of the container. During the descent of the lifting frame 1, the inclined surfaces of the four flip plates 2 contact the corresponding corner fittings in the container. Due to the effect of the inclined surfaces, part of the weight of the lifting frame 1 generates temporary friction on the contact surface between the four flip plates 2 and the inclined surfaces of the corner fittings. This friction can help the lifting frame 1 position the container, reduce the horizontal sliding tendency of the lifting frame 1, and buy time for the final accurate positioning, so that the four flip plates 2 can play a certain anti-slip role. After the four lock heads 4 are respectively aligned with the four corner pieces in the container, the four first drive mechanisms are activated. The movement process of one of the drive mechanisms is as follows: the cylinder 25 is activated, which pushes the connecting block 26 to move. At this time, there is a connecting rod 10 inside the connecting slot 27. So, while the connecting block 26 moves, the hollow seat 7 and the transmission rod 6 outside the connecting rod 10 move synchronously. The hollow seat 7 slides along the two guide rods 9, while the transmission rod 6 pulls the lock head 4 to rotate. The movement process of the other three drive mechanisms is the same as above. The four lock heads 4 rotate and connect with their respective corner pieces. During container hoisting, if a cylinder 25 malfunctions and fails to rotate the corresponding lock head 4, the corresponding adjustment mechanism and the second drive mechanism are operated first. Simultaneously, the corresponding connecting mechanism also operates. The movement process is as follows: First, the threaded rod 24 is rotated. Under the action of the guide rod 23, the adjusting plate 22 gradually rises closer to the T-shaped extension plate 12. During the rising process of the adjusting plate 22, a force is exerted on the trapezoidal plate 18. The trapezoidal plate 18, under this force, drives the U-shaped bracket 14 to move along the two guide rods 15. One side of the U-shaped bracket 14 acts on two positioning blocks 19, both of which are moved away from the connecting rod 10. The corresponding spring 21 extends, and the lower positioning block 19 disengages from the positioning hole 13. When the adjusting plate 22 contacts the T-shaped extension plate 12, as the adjusting plate 22 continues to move upward, the T-shaped extension plate 12 drives the connecting rod 10 to move upward synchronously. At the same time, the adjusting plate 22 does not contact the trapezoidal plate 12. When the trapezoidal plate 18 contacts, the trapezoidal plate 18 drives the U-shaped bracket 14 to reset under the action of two springs 17. When the connecting rod 10 moves to the top, the connecting rod 10 completely disengages from the connecting slot 27. At this time, the corresponding transmission rod 6 disengages from the first drive mechanism, and the staff can then remove the cylinder 25 for maintenance. When the connecting rod 10 moves to the top, the multiple clips 11 at both ends of its top end are inserted into their respective corresponding slots 31, realizing the docking between the connecting rod 10 and the receiving plate 28. In addition, the positioning block 19 located above is inserted into the positioning hole 13 under the action of the corresponding spring 21. Finally, the staff rotates the worm gear 33, thereby driving the turbine 32 and the threaded rod 29 to rotate. Under the action of the guide rod 30, the receiving plate 28 moves, thereby driving the hollow seat 7 below it to move. The corresponding transmission rod 6 moves, thereby allowing the lock head 4 to be controlled again, so that the lock head 4 can rotate and disengage or connect with the corner piece. When reinstalling the damaged cylinder 25 inside the hanger 1, first fix the cylinder 25 inside the hanger 1 and place the connecting block 26 inside the limiting groove 35 to ensure that the cylinder 25 is in its shortest stroke position. Then reverse the threaded rod 24 to reset the adjusting plate 22. At this time, the connecting rod 10 will not move downward under the action of the upper positioning block 19. As the cylinder 25 pushes the connecting block 26 to move, when the connecting block 26 touches the top rod 36, the top rod 36 is forced to move upward, and the pull rod 37 is forced to pull the upper positioning block 19 to slide. The upper positioning block 19 is disengaged from the positioning hole 13. At this time, the connecting rod 10 moves downward under the action of gravity. As the connecting block 26 continues to move, when the connecting rod 10 corresponds to the connecting slot 27, the connecting rod 10 descends to the bottom and enters the connecting slot 27, realizing the connection with the first drive mechanism. At this time, the lower positioning block 19 is locked into the positioning hole 13 under the action of the corresponding spring 21, fixing the position of the connecting rod 10. When the other three cylinders 25 are damaged, the operation process is the same as above. In this invention, for a damaged cylinder 25, the connecting block 26 connected to the cylinder 25 is disengaged from the connecting rod 10 by operating the corresponding connecting mechanism. Simultaneously, the connecting rod 10 is connected to the upper second drive mechanism. The second drive mechanism can then adjust the position of the connecting rod 10 and its external hollow seat 7, thereby adjusting the corresponding transmission rod 6 and locking head 4. Therefore, in the event of a damaged cylinder 25, the locking head 4 can be adjusted via the second drive mechanism to rotate, disengaging or locking the container corner fittings. This solves the problem in the prior art where repairing or replacing the damaged cylinder 25 causes the entire lifting equipment to stop. To address the issue of container lifting efficiency, the remote control system for the port container crane is directly integrated with the lifting device. This allows for remote command control of the lifting device to complete container lifting, transfer, and lowering operations. Simultaneously, thanks to the connecting mechanism, regardless of the position of the damaged cylinder 25 pushing the connecting block 26, the corresponding connecting rod 10 can connect to the second drive mechanism above it. Furthermore, when reinstalling the cylinder 25 and connecting block 26 inside the jack 1, simply pushing the connecting block 26 with the cylinder 25 will connect the connecting rod 10 to the connecting block 26, eliminating the need for personnel to adjust the positions of the connecting rod 10 and connecting block 26.
