Description
Technical Field
[0001] This invention relates to the field of port crane technology, and more particularly to a remote control system for cranes. Background Technology
[0002] Port cranes are large lifting equipment specifically designed for loading, unloading, handling, and stacking of cargo in ports. They refer to specialized lifting machinery installed in port terminals, storage yards, and other areas for loading and unloading cargo between ships and vehicles, transferring cargo in warehouses, and stacking cargo.
[0003] When loading and stacking containers, port cranes cannot lock the twist locks at the bottom of the containers. This requires manual locking after the containers are stacked, or replacing the twist locks with a semi-automatic locking system. The former is cumbersome and reduces the efficiency of container loading and stacking. The latter is more expensive, and the locking effect of semi-automatic twist locks is not as secure as traditional manual twist locks. Therefore, there is an urgent need for a remote control system for port cranes that can automatically lock and disassemble twist locks. Summary of the Invention

[0018] In addition, a preferred structure is that guide grooves are provided on both sides of the movable plate, and guide plates are movably arranged in the guide grooves. One side of the top of the guide plate is connected to the rack, and the other side of the top of the guide plate is connected to the guide block. Furthermore, the upper and lower sides of the guide block are provided with ramps that are adapted to the upper and lower guide balls.
[0019] Furthermore, preferably, the control module includes a drive mechanism, and the assembly steps include:
[0020] S1: The drive mechanism controls the gantry to move above the container at the dock and drives the twist lock to lock onto the corner fittings above the container. Dockworkers install the twist lock on the locking pin, and then the drive mechanism lifts the container.
[0021] S2: The drive mechanism controls the gantry to move the container onto the ship. The laser sensor ensures that the container is aligned with the container below and that the corner fittings at the bottom of the upper container are aligned with the corner fittings at the top of the lower container.

[0052] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0053] See Figure 1-3 6. Corner fittings 21 are provided at each corner of container 2. Four corner fittings 21 are provided on the upper layer and four corner fittings 21 are provided on the lower layer. When loading and stacking containers 2, simply use twist locks 22 to lock the corner fittings 21 between the two sides of containers 2 together. Twist locks 22 are provided with push rods 23. When in use, simply rotate push rods 23. Each push rod 23 has a locking cavity 231, and the locking cavity 231 is adapted to the locking pin 46.
[0054] Each corner piece 21 at the bottom of the jack 1 is fitted with a rotary lock 10. By locking the corner pieces 21 with the rotary lock 10, the jack 1 can lift the container 2.
[0055] It is worth noting that the specific structures and working methods of the rotary lock 10, twist lock 22 and corner piece 21 are all existing technologies, so they will not be described in detail.
[0056] See Figure 4-5 Side plates 11 are installed on both sides of the hanger 1, and first guide columns 13 are installed on both sides of the bottom of the side plates 11. The movable plate 3 is guided to move by the first guide columns 13, and rotating columns 4 are rotatably provided on both sides of the movable plate 3.
[0057] Each side plate 11 is equipped with a winch 12 on its top, and the movable plates 3 are moved vertically by the traction ropes on the winches 12. It is worth noting that the specific structure and operation of the winch 12 are existing technologies and are not part of the main technical problem to be solved in this technical solution, so they will not be described in detail in this invention.
[0058] See Figure 7-8 Each of the first guide columns 13 is equipped with an electric slide rail 131. Both the upper support 14 and the lower support 15 move vertically via the electric slide rail 131. An upper guide ball 141 is fixedly mounted on each of the upper support 14, and a lower guide ball 151 is fixedly mounted on each of the lower support 15. The electric slide rail 131 allows the upper support 14 and the lower support 15 to move vertically on the first guide column 13, thereby adjusting their positions. The electric slide rail 131 is existing technology and will not be described in detail further.
[0059] Each of the lower brackets 15 has a sub-magnetic plate 152 fixedly mounted on it. A mounting base 153 is fixedly mounted on one side of each sub-magnetic plate 152 on the lower bracket 15, and a sub-magnetic block 154 is fixedly mounted on each mounting base 153. This allows the lower bracket 15 to move the sub-magnetic plate 152 and the sub-magnetic block 154 synchronously. The mounting base 153 is located at the bottom of the sub-magnetic block 154 and is made of a magnetically shielding material. By using the mounting base 153, when the sub-magnetic block 154 is above the mother magnetic block 465, the magnetic force between the mother magnetic block 465 and the sub-magnetic block 154 can be significantly reduced.
[0060] See Figure 9-16 Both sides of the movable plate 3 are vertically connected with rotating columns 4, and a top seat 43 is fixedly installed on the top of the rotating column 4. An arc plate 44 is fixedly installed on the top seat 43.
[0061] The arc-shaped plate 44 has a movable cavity 441 inside, and the locking pin 46 is adapted to move within the movable cavity 441. A bottom block 462 is fixedly provided at the bottom of the locking pin 46, and a female magnetic block 465 is fixedly provided on the outer side of the bottom block 462, and the female magnetic block 465 is adapted to repel the female magnetic block 154.
[0062] The repulsive magnetic force between the female magnetic block 465 and the female magnetic block 154 can lift the female magnetic block 465 upwards, thereby causing the locking pin 46 to move upwards synchronously. It is worth noting that the female magnetic block 465 and the female magnetic block 154 are not on the same vertical plane, which allows the female magnetic block 465 to pass through one side of the female magnetic block 154 when it moves downwards.
[0063] In this design, a fixing plate 431 is fixedly installed on one side of the top seat 43. A second guide post 432 is fixedly arranged between the fixing plate 431 and the arc-shaped plate 44. The locking plates 45 are guided to move by the second guide post 432, and the locking plates 45 and the fixing plate 431 are connected by multiple springs 433. The springs 433 can stably push the locking plates 45 towards the locking post 46. It is worth noting that the springs 433 are damping shock-absorbing springs in the prior art to ensure preload under extreme conditions.
[0064] The locking plate 45 is fixedly equipped with an upper locking member 451 and a lower locking member 454. The locking pin 46 has an upper locking cavity 461 adapted to the upper locking member 451, and the bottom block 462 has a lower locking cavity 464 adapted to the lower locking member 454. In this way, the locking plate 45 can limit and fix the locking pin 46 to ensure that the locking pin 46 can stably lock the locking cavity 231 on the push rod 23.
[0065] A female magnetic plate 452 is fixedly installed on one side of the card plate 45, and the female magnetic plate 452 and the male magnetic plate 152 are compatible and attracted to each other. When the male magnetic plate 152 moves to one side of the female magnetic plate 452, the female magnetic plate 452 can be attracted by the male magnetic plate 152 through the magnetic force of attraction, thereby driving the card plate 45 to move outward.
[0066] The bottom block 462 has a female wedge block 463 fixedly mounted on its top, and a male wedge block 453 adapted to the bottom of the locking plate 45. A through cavity 455 is also adapted to the female wedge block 463 on the lower locking member 454. This adaptation between the male wedge block 453 and the female wedge block 463 allows the locking pin 46 to push the locking plate 45 outwards when it moves upwards.
[0067] See Figure 17 Each rotating column 4 has a base 42 fixedly installed at its bottom, and a locking push block 421 and a reset push block 422 are fixedly installed on the base 42. The locking push block 421 is located above the reset push block 422, and the locking push block 421 and the reset push block 422 are not in the same direction. This allows the device to freely adjust the angle of the locking push block 421 or the reset push block 422 to align it with the torsion lock 22 under the container 2.
[0068] See Figure 18-19 Both sides of the movable plate 3 are provided with guide grooves 32, and guide plates 33 are movably installed in each guide groove 32. Multiple guide rods are provided in the guide grooves 32 to ensure the stability of the guide plates 33 during movement.
[0069] One side of the top of the guide plate 33 is connected to the rack 31, and the other side of the top of the guide plate 33 is connected to the guide block 34. The upper and lower sides of the guide block 34 are provided with ramps that are adapted to the upper guide ball 141 and the lower guide ball 151.
[0070] When the movable plate 3 moves vertically, it drives the guide block 34 to move synchronously. When the guide block 34 contacts the upper guide ball 141 or the lower guide ball 151, it can be pushed, thereby driving the guide plate 33 and the rack 31 to move synchronously through the movement of the guide block 34. In this way, the movement of the rack 31 drives the gear 41 to rotate, thereby driving the rotating column 4 to rotate. It is worth noting that the gear 41 and the rack 31 are meshed, which is existing technology and will not be described in detail. Furthermore, when the rack 31 moves to its maximum stroke, the gear 41 drives the rotating column 4 to rotate by an angle of 90°.
[0071] See Figure 20-21 The structures proposed in this device are all remote control terminals for cranes. Users operate them from the ground through the control module.
[0072] The gantry 1 is moved by a driven mechanism via a traction rope. Multiple sensor components, including tilt sensors, wind speed sensors, and displacement sensors, are installed inside the gantry 1 to monitor its foundation. Furthermore, multiple cameras are installed on the gantry 1 to monitor the position and status of components such as the torsion lock 22. These are all existing technologies and will not be elaborated upon further.
[0073] In this embodiment, when it is necessary to lift the container 2 on the dock, the jack 1 is simply moved above the container 2 on the dock by the drive mechanism, and the rotary lock 10 is driven to lock onto the corner piece 21 above the container 2.
[0074] At this point, the movable plates 3 on both sides of the hanger 1 are positioned above, which means that the top seat 43 and the arc plate 44 on the rotating column 4 are both positioned above the movable plates 3. The user then simply needs to install the torsion lock 22 on the locking column 46.
[0075] When the user equips all the locking pins 46 with twist locks 22, the gantry crane 1 can be controlled by the drive mechanism to lift the container 2, and then the dock container 2 can be moved above the cargo ship container 2 for stacking. A laser sensor ensures alignment between the upper and lower container 2, and ensures that the corner fittings 21 at the bottom of the upper container 2 are properly aligned with the corner fittings 21 at the top of the lower container 2. At this time, the twist locks 22 on the corner fittings 21 at the top of the lower container 2 are properly inserted into the corner fittings 21 at the bottom of the upper container 2.
[0076] Next, the twist lock 10 is released from the corner piece 21 on the top of the upper container 2 by the drive mechanism, and the gantry 1 is moved up a certain distance to move the side plate 11 to the designated position A. At this time, the installation of the twist lock 22 on the upper corner piece 21 of the upper container 2 can begin.
[0077] When installing the twist lock 22, it is necessary to ensure that the upper bracket 14 and the lower bracket 15 are located at the height of the first guide column 13. At this time, the winch 12 controls the movable plate 3 to move downward so that the guide block 34 and the rotating column 4 move downward synchronously. When the guide block 34 contacts the lower guide ball 151 on the lower bracket 15, as the movable plate 3 moves downward, the guide block 34 can be pushed to move laterally synchronously through the matching setting between the ramp at the bottom of the guide block 34 and the lower guide ball 151.
[0078] At this time, the guide block 34 moves away from the corner piece 21. During the outward movement of the guide block 34, it can drive the guide plate 33 and the rack 31 to move synchronously. In this way, the movement of the rack 31 can drive the gear 41 to rotate, thereby driving the rotating column 4 to rotate. At this time, the arc plate 44 and the locking push block 421 on the rotating column 4 both rotate towards the corner piece 21, and the torsion lock 22 mounted on the arc plate 44 moves to the top of the corner piece 21.
[0079] The user then continues to control the movable plate 3 to move downwards via the winch 12, thereby moving the bottom of the twist lock 22 into the corner piece 21. As the movable plate 3 moves downwards, the locking plate 45 moves to one side of the sub-magnetic plate 152, and at this time, the female magnetic plate 452 on the locking plate 45 and the sub-magnetic plate 152 are aligned. At this time, the female magnetic plate 452 can be attracted by the sub-magnetic plate 152 by magnetic force, and the female magnetic plate 452 can overcome the elastic force of the spring 433 and move towards the sub-magnetic plate 152, thereby driving the locking plate 45, the upper locking piece 451, and the lower locking piece 454 to move synchronously. At this time, the upper locking piece 451 is no longer locked in the upper locking cavity 461, and the lower locking piece 454 is no longer locked in the lower locking cavity 464. The locking pin 46 can then fall automatically by gravity, thereby releasing the alignment between the locking pin 46 and the locking cavity 231, thus realizing the installation of the twist lock 22 on the top of the upper container 2.
[0080] Since the locking push block 421 is facing the twist lock 22 at the bottom of the upper container 2, it is only necessary to continue to control the movable plate 3 to move down through the winch 12, and cooperate with the drive mechanism to drive the hanger 1 to move down, so as to move the locking push block 421 down a greater distance until the locking push block 421 contacts the push rod 23 on the twist lock 22 at the bottom of the upper container 2. In this way, the push rod 23 can be pushed towards the locking end by the inclined surface at the bottom of the locking push block 421, thereby locking the twist lock 22 at the bottom of the upper container 2. At this time, the containers 2 can be stacked and installed. During the installation of containers 2, new twist locks 22 can be installed on top of the container 2 to facilitate the installation of subsequent containers 2.
[0081] After installation, the hoist 12 controls the movable plate 3 to move upward, causing the guide block 34 and the rotating column 4 to move upward synchronously. When the guide block 34 contacts the upper guide ball 141 on the upper bracket 14, it can drive the guide block 34 and the rack 31 to reset via the inclined plane. Thus, the movement of the rack 31 drives the gear 41 to rotate in the opposite direction, thereby driving the rotating column 4 to reset, and driving the top seat 43 to rotate and reset above the movable plate 3.
[0082] Furthermore, when unloading container 2, the gantry crane 1 is simply moved to the designated position A above container 2 on the cargo ship via the drive mechanism, and positioned using a laser sensor. During the unloading process, the upper support 14 and lower support 15 on the first guide column 13 are moved to their lowest positions via the electric slide rail 131.
[0083] Then, the winch 12 controls the movable plate 3 to move downwards, causing the guide block 34 to move downwards synchronously. When the guide block 34 contacts the lower guide ball 151 on the lower bracket 15, it pushes the guide block 34 outwards again. This movement of the guide block 34 causes the guide plate 33 and rack 31 to move synchronously, which in turn causes the rack 31 to rotate. This causes the rotating column 4, locking push block 421, and top seat 43 to rotate towards the corner piece 21.
[0084] Then, the winch 12 continues to control the movable plate 3 to move downward, so as to move the arc plate 44 on the top seat 43 to below the push rod 23 of the twist lock 22, and make the locking pin 46 on the arc plate 44 and the locking cavity 231 on the push rod 23 fit and align. At this time, the movement of the movable plate 3 is completed.
[0085] As the movable plate 3 moves, the female magnetic block 465 gradually approaches the female magnetic block 154. At this time, the repulsive magnetic force between the female magnetic block 154 and the female magnetic block 465 can push the female magnetic block 465 upward, thereby moving the entire locking pin 46 upward. It is worth noting that the magnetic properties of the female magnetic block 154 and the female magnetic block 465 are relatively large, giving them sufficient magnetic force to push the locking pin 46.
[0086] When the locking pin 46 moves upward, it can be inserted into the locking cavity 231 on the push rod 23. Furthermore, as the locking pin 46 moves upward, it can drive the female wedge block 463 to move upward synchronously. This allows the locking plate 45 to be pushed outward through the fitting arrangement between the female wedge block 463 and the female wedge block 453, at which point the spring 433 is compressed.
[0087] As the locking pin 46 continues to move, after the female wedge block 463 passes through the through cavity 455 in the lower locking member 454, the upper locking member 451 and the upper locking cavity 461 are aligned, and the lower locking member 454 and the lower locking cavity 464 are also aligned. At this time, the female wedge block 463 can no longer push the female wedge block 453 and the lower locking member 454 outward, so the locking plate 45 can automatically reset by the elastic force of the spring 433, so that the upper locking member 451 and the lower locking member 454 are properly inserted into the upper locking cavity 461 and the lower locking cavity 464. In this way, the locking pin 46 and the push rod 23 can be locked, so that the torsion lock 22 can move synchronously with the locking pin 46 and the arc plate 44 in the future.
[0088] Next, the winch 12 controls the movable plate 3 to move upward, causing the guide block 34 and the rotating column 4 to move upward synchronously. When the guide block 34 contacts the upper guide ball 141 on the upper support 14, it can drive the guide block 34 and the rack 31 to reset via the inclined plane. Thus, the movement of the rack 31 drives the gear 41 to rotate in the opposite direction, thereby driving the rotating column 4 to reset, which in turn drives the top seat 43, the arc plate 44, and the torsion lock 22 to rotate and reset above the movable plate 3, thereby achieving the disassembly of the torsion lock 22 on the upper layer of the upper container 2.
[0089] At this point, the entire jack 1 is lowered by the drive mechanism so that the twist lock 10 on the jack 1 comes into contact with the corner piece 21 on the top of the upper container 2. Since the twist locks 22 on the corner piece 21 are removed at this time, the twist lock 10 can be directly inserted into the corner piece 21 and locked.
[0090] Since the rotating column 4 also resets synchronously after the movable plate 3 moves upward and resets, the reset push block 422 on the base 42 is now facing the container 2 again. Therefore, during the downward movement of the hanger 1, the bottom of the reset push block 422 contacts the push rod 23 on the torsion lock 22 at the bottom of the upper container 2. Thus, the push rod 23 can be pushed towards the reset loose end by the inclined surface at the bottom of the reset push block 422, thereby releasing the torsion lock 22 at the bottom of the upper container 2.
[0091] Finally, the crane 1 is controlled by the drive mechanism to move the container 2 to the dock. After the container 2 is lowered, the dock workers can remove the torsion lock 22 on the locking post 46.
[0092] Furthermore, when the movable plate 3 is in the upper position, the guide block 34 is pushed by the upper guide ball 141 and moves closer to the middle of the hanger 1, thereby driving the rack 31 to move synchronously, which in turn drives the gear 41 and the rotating column 4 to rotate. Therefore, when the movable plate 3 is in the upper position, the top seat 43 and the arc plate 44 on the rotating column 4 are both located above the movable plate 3. At this time, the reset push block 422 faces the middle of the hanger 1, and the push rod 23 can be pushed by the reset push block 422.
[0093] When the movable plate 3 is at the bottom, the guide block 34 is pushed away from the hanger 1 by the lower guide ball 151, so as to drive the rack 31 to move synchronously, thereby driving the gear 41 and the rotating column 4 to rotate. Therefore, when the movable plate 3 is at the bottom, the top seat 43 and the arc plate 44 on the rotating column 4 are facing the middle of the hanger 1, while the reset push block 422 is no longer facing the hanger 1.
[0094] Furthermore, since the arc plate 44 needs to be moved to its bottom before the twist lock 22 can be disassembled, the required rotation height of the arc plate 44 varies during the installation or disassembly of the twist lock 22. Therefore, by controlling the movement of the upper bracket 14 and the lower bracket 15 via the electric slide rail 131, it can be ensured that the arc plate 44 can rotate at the specified height during the installation or disassembly of the twist lock 22.
[0095] Furthermore, since both the sub-magnetic plate 152 and the sub-magnetic block 154 are fixedly mounted on the lower bracket 15, they can move synchronously with the lower bracket 15. When the torsion lock 22 is installed on the corner piece 21, the lower bracket 15 is positioned above. At this time, the sub-magnetic plate 152 can generate magnetic force with the mother magnetic plate 452 to drive the locking plate 45 to move. However, at this time, the sub-magnetic block 154 cannot generate magnetic force because the distance between it and the mother magnetic block 465 is too far.
[0096] When the torsion lock 22 is removed from the corner piece 21, the lower bracket 15 moves downward. At this time, the sub-magnetic block 154 can generate a repulsive magnetic force with the female magnetic block 465, thereby driving the locking pin 46 to move upward. Meanwhile, the sub-magnetic plate 152 cannot generate a magnetic force due to misalignment with the female magnetic plate 452.
[0097] Furthermore, when dockworkers need to install the twist lock 22 onto the locking pin 46, they simply lift the locking pin 46 halfway up and place the push rod 23 on the twist lock 22 onto the locking pin 46. Then, by continuing to lift the locking pin 46 upwards, the upper locking piece 451 and the lower locking piece 454 on the locking plate 45 will automatically engage with the locking pin 46, thus installing the twist lock 22 onto the locking pin 46.
[0098] When removing the twist lock 22 on the locking pin 46, simply pull the retaining plate 45 outwards, and the locking pin 46 will automatically fall down, thus enabling the installation of the twist lock 22.
[0099] This allows dockworkers to install or remove the twist lock 22 on the locking pin 46 from the ground, eliminating the need to operate the twist lock 22 on the container 2 from a height. Furthermore, this method only requires installation of the twist lock 22, eliminating the need for locking and unlocking operations, thus improving efficiency. The twist lock 22 used in this invention is a slight modification of the existing manual twist lock, featuring only a locking cavity 231, making it less expensive than a semi-automatic twist lock while retaining the structural stability of a manual twist lock.
[0100] Furthermore, the designated position A proposed in this invention varies depending on the height of the container 2 and the height of the corner piece 21 in actual situations, and needs to be calculated according to the actual situation. It is only necessary to ensure that the installation and disassembly of the twist lock 22 can be realized under the designated position A in this embodiment. Moreover, the designated position A proposed in this invention is based on the container 2.
[0101] In this invention, the container 2 can be moved by the hanger 1. Through the adaptation between the movable plate 3 and the rotating column 4, the torsion lock 22 can be automatically installed on the top of the container 2 and locked on the torsion lock 22 at the bottom of the container 2 during the loading and stacking process. During the unloading process of the container 2, the torsion lock 22 on the top of the container 2 can be automatically removed and the torsion lock 22 at the bottom of the container 2 can be loosened to release the locking of the container 2. This method of operating the container 2 is fast, convenient and low cost.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
