Description

Technical Field

[0001] The present invention relates to the technical field of ship transportation, and particularly to a loading and unloading system and working method for a ship container terminal. Background Art

[0002] When a ship is engaged in ocean transportation, due to the large waves on the sea, the overall shaking of the ship will occur. If the containers are not fixed firmly, the containers will fall off, and in severe cases, the ship will capsize. The commonly used fixing machines are often manually operated by personnel to fix the containers, which is relatively cumbersome and prone to negligence. It is inconvenient during container loading and unloading. Moreover, when multiple containers are stacked, the upper container requires the operator to be very skilled in using a crane to place it. During the lowering process, a traditional machine vision system is usually used for multiple position corrections to ensure the precise alignment and stacking of the two containers. However, this positioning and correction link is cumbersome and time-consuming, resulting in an extended overall operation cycle. Summary of the Invention

[0003] The purpose of the present invention is to provide a loading and unloading system and working method for a ship container terminal to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A loading and unloading system for a ship container terminal, comprising a spreader, a guiding device, and a plurality of fixing platforms. The plurality of fixing platforms are installed on the deck of the ship. The top surface of the fixing platform is provided with a fixing groove adapted to the container. Fixed seats are arranged at both the left and right ends of the fixing platform. A connecting frame is slidably assembled on the top of the fixed seat. A winding drum and a motor are rotatably arranged in the fixed seat. The motor is in transmission connection with the winding drum to drive the winding drum to rotate. Line wheels are arranged at both ends of the winding drum. A fixing rope is wound around the line wheel. One end of the fixing rope is connected to the connecting frame.

The guiding device includes two sets of guiding mechanisms arranged symmetrically. A fixing component matching the connecting frame is provided at its bottom. Power components are arranged on both sides at the bottom of the guiding mechanism. When the guiding mechanism is docked with the connecting frame, the power component is in transmission connection with the twisting lock to drive the twisting lock to rotate. Support frames and first telescopic cylinders are slidably assembled at both the left and right ends of the spreader. The first telescopic cylinder is used to drive the support frame to displace horizontally. During the descending process, the support frame contacts the guiding mechanism and slides along its guiding channel to complete guiding and positioning. A connecting component adapted to the guiding mechanism is arranged on the support frame, so that when the support frame displaces to the lower limit position, it can be connected to the guiding mechanism.

[0006] Furthermore, electromagnets are embedded on both sides of the end surface of the mounting frame close to the fixing groove, and a power supply is provided on the mounting frame, and the power supply is electrically connected to the electromagnet.

[0007] Furthermore, the power assembly includes an insertion block arranged on both sides of the bottom end of the mounting frame, the insertion block is rotatably connected to a driving wheel, a second motor is arranged on both sides of the mounting frame, the second motor is transmission-connected to the driving wheel on the corresponding side, and sockets matching the insertion block are provided on both sides of the top end of the connecting frame, a driven wheel is rotatably connected in the socket, and the rotating shaft of the driven wheel extends through and is connected to the twist lock on the corresponding side. When the insertion block is inserted into the socket, the driving wheel abuts against the driven wheel, thereby driving the driven wheel to rotate through the driving wheel.

[0008] Furthermore, the fixing assembly includes a first anchor seat arranged in the middle of the bottom end of the mounting frame, a first clamping rod is slidably embedded in both left and right ends of the first anchor seat, a first telescopic cylinder is arranged in the first anchor seat, a first support is arranged at the end of the piston rod of the first telescopic cylinder, both sides of the first support are hingedly connected with a first driving rod, the other end of the first driving rod is hingedly connected to the inner end of the first clamping rod on the corresponding side, so that the first clamping rod is driven to move laterally by the first telescopic rod; a first clamping groove matched with the first anchor seat is provided in the middle of the top end of the connecting frame, and first clamping holes matched with the first clamping rod are provided on the inner walls on both sides of the first clamping groove.

[0009] Further, the connection component includes a second anchoring seat arranged in the middle of the bottom end of the support frame. Both the left and right ends of the second anchoring seat are slidably embedded with second clamping rods. A second telescopic cylinder is arranged in the second anchoring seat. The end of the piston rod of the second telescopic cylinder is provided with a second support. Both sides of the second support are hinged with second driving rods. The other end of the second driving rod is hinged with the inner end of the second clamping rod on the corresponding side, so as to drive the second clamping rod to perform a lateral displacement through the second telescopic rod; a limiting groove is formed in the inner wall of the guiding frame and a sliding rod is arranged in the limiting groove. A moving frame is connected between the two guiding frames, and the moving frame is slidably assembled on the sliding rod. A spring is sleeved on the sliding rod, and the spring is connected between the bottom of the moving frame and the bottom end of the limiting groove. A second clamping groove adapted to the second anchoring seat is formed in the middle of the top end of the moving frame, and second clamping holes adapted to the second clamping rods are formed in both inner walls of the second clamping groove.

[0010] Further, the structure of the spreader can refer to the existing container spreader. The present invention adds support frames that can be telescoped on both sides to the structure of the existing spreader.

[0011] Further, the fixing rope is a steel wire rope.

[0012] Further, the driving wheel is a gear or a metal friction wheel, and the driven wheel is a gear or a runner coated with a material with a high friction coefficient.

[0013] The present invention also provides a working method for the above-mentioned loading and unloading system, including the following steps: S1. Deploy a fixed platform on the ship deck; S2. During the container loading stage, install the spreader on the quay crane, and fix the guiding mechanisms on the support frames on both sides of the spreader through the connection component respectively; the spreader hoists the container to the designated fixed platform. While the container is lowered to the fixed platform, the mounting frame is fixedly connected with the connecting frame through the fixing component. Then, the connection component releases the connection with the guiding mechanism, and the spreader releases the container and goes to hoist the next container; S3. When the next container is hoisted above the fixed platform, when the spreader descends, the guiding balls on its upper support frame slide down along the progressive guiding groove at the top of the guiding frame, so as to eliminate the horizontal offset of the spreader and achieve positioning. Finally, the two containers are aligned and stacked; S4. After a plurality of containers are stacked in sequence, when stacking the final layer of containers, the spreader is connected with the guiding mechanism through the connection component, and then the spreader drives the guiding mechanism to rise. At the same time, the reel synchronously releases the fixing rope until the connecting frame rises to the top corner fitting of the topmost container. The telescopic cylinder drives the support frame to displace inwards, so that the twist lock is inserted into the corner fitting. The power component drives the twist lock to rotate, so that it enters the vertical locking state and fixes the connecting frame to the container; S5. Disconnect the fixing component from the connecting frame, and the spreader drives the guiding mechanism to move to the next fixing platform.

[0014] Further, it also includes: S6. During the stage of discharging containers from the ship, the twist lock can be unlocked by the staff, or the guiding mechanism can be lifted and transported by the spreader, and the power component thereon is used for unlocking; when the twist lock is unlocked and leaves the corner fitting, the winding drum retrieves the fixing rope, so that the connecting frame retracts into the fixing seat again.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The guiding frame of the guiding mechanism adopts a top-down shrinking guide groove (geometric constraint), combined with the guiding ball at the end of the support frame, gradually corrects the horizontal offset during the lowering process of the spreader, and realizes precise positioning. Compared with the traditional method relying on the vision system or manual calibration, this system only needs to operate the spreader to lower to complete precise positioning, improving the stacking efficiency.

[0016] 2. The design of the connecting frame and the fixing rope of the present invention locks and fixes the connecting frame with the container corner fitting through the spreader during the loading and unloading process, forming a flexible constraint on the top-layer container. When the ship sways, the fixing rope can buffer the impact force to prevent the container from shifting. At the same time, the twist lock provides rigid fixation to ensure stability, eliminating the need for manual fixation, saving time and effort.

[0017] 3. The independent modular design of the guiding mechanism, the connecting frame and the support frame of the present invention, and the use of the clamping rod and the clamping hole to achieve quick connection and separation. The same set of guiding mechanism can be transferred to different fixing platforms through the spreader, reducing the equipment cost. Description of the Drawings

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figures 1 to 10 shown, a loading and unloading system for a ship container terminal includes a spreader 1, a guiding device, and a plurality of fixed platforms 2. The plurality of fixed platforms 2 are installed on the deck of the ship. The top surface of the fixed platform 2 is provided with a fixed groove 3 adapted to the container 31. Fixed seats 4 are arranged at both the left and right ends of the fixed platform 2. A connecting frame 5 is slidably assembled on the top of the fixed seat 4. A reel 6 and a motor are rotatably arranged in the fixed seat 4. The motor is in transmission connection with the reel 6 to drive the reel 6 to rotate. Line wheels are arranged at both ends of the reel 6, and a fixed rope 7 is wound around the line wheels. One end of the fixed rope 7 is connected to the connecting frame 5. Twist locks 8 adapted to the corner fittings of the container 31 are rotatably arranged on both sides of the end face of the connecting frame 5 close to the fixed groove 3; The guiding device includes two sets of guiding mechanisms arranged symmetrically. A fixing component matching the connecting frame 5 is provided at its bottom, and power components are arranged on both sides of the bottom of the guiding mechanism. When the guiding mechanism is docked with the connecting frame 5, the power component is in transmission connection with the twist lock 8 to drive the twist lock 8 to rotate. Support frames 9 and telescopic cylinders are slidably assembled at both the left and right ends of the spreader 1. The telescopic cylinder is used to drive the support frame 9 to displace horizontally. During the descending process, the support frame 9 contacts the guiding mechanism and slides along its guiding channel to complete guiding and positioning. A connecting component adapted to the guiding mechanism is arranged on the support frame 9, so that when the support frame 9 displaces to the lower limit position, it can be connected to the guiding mechanism.

[0022] In this embodiment, the guiding mechanism includes two symmetrically arranged guiding frames 10 and a mounting frame 11. The two guiding frames 10 are fixedly installed on both sides of the top of the mounting frame 11, and a guiding frame 12 is arranged on the top of the guiding frame 10. The structure thereof is in a progressively contracted form from top to bottom, and the guiding path of the guiding frame 10 and the guiding groove of the guiding frame 12 form a continuous guiding channel. Both ends of the supporting frame 9 are provided with guiding balls 13. During the descending process, the guiding balls 13 gradually adjust the motion trajectory through the guiding groove of the guiding frame 12, and are finally accurately guided into the guiding path of the guiding frame 10, thereby driving the synchronous guidance of the container 31 hoisted on the sling 1. Through the retractable guide groove on the top of the guide frame 10 and the continuous channel design of the guide frame 12, the guide ball 13 at the end of the support frame 9 of the spreader 1 gradually adjusts the horizontal offset under geometric constraints during the falling process, achieving millimeter-level positioning accuracy. Without the need for a visual system, the staff only needs to operate the spreader 1 to descend to automatically adjust the position of the container 31, and the subsequent layers of containers 31 are automatically calibrated and stacked through the guiding mechanism.

[0023] In this embodiment, electromagnets 14 are embedded on both sides of the end surface of the mounting frame 11 close to the fixing groove 3, and a power supply is provided on the mounting frame 11, and the power supply is electrically connected to the electromagnet 14; when the height of the stacked containers 31 exceeds the length of the guide frame 10, after the sling 1 completes the stacking of the containers 31 of this layer, the support frame 9 and the mounting frame 11 are connected through the connecting assembly, and then the sling 1 rises vertically, thereby driving the mounting frame 11 to rise vertically to the top container 31, and then the support frame 9 moves inward under the action of the telescopic cylinder, so that the electromagnet 14 on the mounting frame 11 fits the surface of the container 31, and then the electromagnet 14 is energized so that it is magnetically adsorbed and fixed on the container 31. At this time, the guide frame 10 on the mounting frame 11 continues to extend out of the top container 31 due to the position adjustment, and can continue to guide the subsequent lifting.

[0024] In this embodiment, the power assembly includes an insertion block 15 arranged on both sides of the bottom end of the mounting frame 11, and a driving wheel 16 is rotatably connected to the insertion block 15. A second motor 17 is arranged on both sides of the mounting frame 11, and the second motor 17 is transmission-connected to the driving wheel 16 on the corresponding side. Sockets 18 adapted to the insertion block 15 are provided on both sides of the top of the connecting frame 5, and a driven wheel 19 is rotatably connected in the socket 18, and the rotating shaft of the driven wheel 19 extends through and is connected to the twist lock 8 on the corresponding side. When the insertion block 15 is inserted into the socket 18, the driving wheel 16 abuts against the driven wheel 19, thereby driving the driven wheel 19 to rotate through the driving wheel 16.

[0025] In this embodiment, the fixing component includes a first anchoring seat 20 arranged in the middle of the bottom end of the mounting frame 11. The left and right ends of the first anchoring seat 20 are both slidably embedded with first clamping rods 21. A first telescopic cylinder 22 is arranged in the first anchoring seat 20. The end of the piston rod of the first telescopic cylinder 22 is provided with a first support 23. Both sides of the first support 23 are hingedly connected with first driving rods 24. The other end of the first driving rod 24 is hingedly connected with the inner end of the first clamping rod 21 on the corresponding side, so as to drive the first clamping rod 21 to perform a lateral displacement through the first telescopic rod; a first clamping groove 25 adapted to the first anchoring seat 20 is opened in the middle of the top end of the connecting frame 5. First clamping holes 26 adapted to the first clamping rods 21 are opened on both inner walls of the first clamping groove 25; When the mounting frame 11 and the connecting frame 5 are docked, the first anchoring seat 20 will be inserted into the first clamping groove 25. If it is necessary to fixedly connect the two, the piston rod of the first telescopic cylinder 22 is controlled to extend, so as to push the first clamping rods 21 on both sides to extend through the first driving rods 24 and extend into the first clamping holes 26, thereby completing the clamping; on the contrary, when disconnecting the connection, the piston rod of the first telescopic cylinder 22 is retracted, and the first clamping rods 21 can be driven to leave the first clamping holes 26.

[0026] In this embodiment, the connecting component includes a second anchoring seat 27 arranged in the middle of the bottom end of the support frame 9. The left and right ends of the second anchoring seat 27 are both slidably embedded with second clamping rods 32. A second telescopic cylinder is arranged in the second anchoring seat 27. The end of the piston rod of the second telescopic cylinder is provided with a second support. Both sides of the second support are hingedly connected with second driving rods. The other end of the second driving rod is hingedly connected with the inner end of the second clamping rod 32 on the corresponding side, so as to drive the second clamping rod 32 to perform a lateral displacement through the second telescopic rod; a limiting groove 28 is opened on the inner wall of the guiding frame 10. And a sliding rod is arranged in the limiting groove 28. A moving frame 29 is connected between the two guiding frames 10. And the moving frame 29 is slidably assembled on the sliding rod. A spring is sleeved on the sliding rod. The spring is connected between the bottom of the moving frame 29 and the bottom end of the limiting groove 28. A second clamping groove 30 adapted to the second anchoring seat 27 is opened in the middle of the top end of the moving frame 29. Second clamping holes 31 adapted to the second clamping rods 32 are opened on both inner walls of the second clamping groove 30; Since the length of the guiding frame 10 is greater than the height of the container 31, when the spreader 1 stacks the containers 31, the support frame 9 will contact the moving frame 29. At this time, the liftable design of the moving frame 29 will not affect the lifting work of the spreader 1. And under the resilience of the spring, when the spreader 1 leaves the guiding frame 10, the moving frame 29 will automatically reset to the top of the limiting groove 28. When the spreader 1 needs to be connected to the guiding mechanism, the support frame 9 and the moving frame 29 are connected into one body through the first clamping rod 21. At this time, the guiding mechanism can be driven to move by the movement of the spreader 1.

[0027] This embodiment also discloses a working method of the above loading and unloading system, including the following steps: S1. Deploy the fixed platform 2 on the ship deck; S2. During the stage of loading the container 31 onto the ship, install the spreader 1 on the quay crane, and fix the guiding mechanism to the supporting frames 9 on both sides of the spreader 1 through the connecting components; the spreader 1 hoists the container 31 to the designated fixed platform 2. When the container 31 is lowered to the fixed platform 2, the mounting frame 11 is fixedly connected to the connecting frame 5 through the fixing components. Then, the connecting components are disconnected from the guiding mechanism, and the spreader 1 releases the container 31 and goes to hoist the next container 31; S3. When the next container 31 is hoisted above the fixed platform 2, as the spreader 1 descends, the guiding balls 13 on its upper supporting frame 9 slide down along the progressive guide groove at the top of the guiding frame 10, thereby eliminating the horizontal offset of the spreader 1 and achieving positioning. Finally, the two containers 31 are aligned and stacked; S4. After multiple containers 31 are stacked in sequence, when stacking the final layer of the container 31, the spreader 1 is connected to the guiding mechanism through the connecting components, and then the spreader 1 drives the guiding mechanism to rise. At the same time, the winding drum 6 synchronously releases the fixing rope 7 until the connecting frame 5 rises to the top corner fitting of the topmost container 31. The telescopic cylinder drives the supporting frame 9 to displace inward, so that the twist lock 8 is inserted into the corner fitting. The power component drives the twist lock 8 to rotate, making it enter the vertical locking state, and fixing the connecting frame 5 to the container 31. The twist lock corner fitting mechanism in the prior art can be used to connect between the containers 31, and then the motor is used to tighten the fixing rope 7 to fix and restrain the topmost container 31, thereby preventing the container 31 from shaking caused by the ship's sway; S5. Disconnect the fixing components from the connecting frame 5, and the spreader 1 drives the guiding mechanism to move to the next fixed platform 2; S6. During the stage of unloading the container 31 from the ship, the staff can unlock the twist lock 8, or the spreader 1 hoists the guiding mechanism and uses the power component thereon to unlock it; when the twist lock 8 is unlocked and leaves the corner fitting, the winding drum 6 retracts the fixing rope 7, so that the connecting frame 5 retracts back into the fixed seat 4 again.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
