Description

Technical Field

[0001] This invention relates to a dry cargo receiving device for marine replenishment, and more particularly to an integrated retractable dry cargo receiving device and control method. Background Technology

[0002] At-sea replenishment is a crucial guarantee for large ships to navigate the deep blue sea and complete their ocean-going missions. For large ships, a large amount of supplies such as fuel, fresh water, equipment spare parts, food, and medicine are essential for maintaining their ocean-going capabilities. Their onboard replenishment receiving equipment is a vital support device for at-sea replenishment and determines their ability to conduct ocean-going voyages.

[0003] Compared to liquid cargo replenishment, dry cargo replenishment requires cooperation between the sending and receiving ends to complete the task, making dry cargo replenishment receiving equipment a crucial component of maritime replenishment. However, due to space and weight limitations on ships, traditional dry cargo replenishment receiving equipment is clearly insufficient to meet these requirements. Summary of the Invention

[0004] The technical problem to be solved by this invention is:

[0005] 1. Implement a retractable function, allowing the compartment to be stored on the top when not in use, thus optimizing the use of space in the compartment;

[0006] 2. The integrated retractable dry goods replenishment receiving device is driven by a motor directly driving a ball screw, which causes the lifting slider on the screw to move the receiving head up and down to maintain the height difference during the goods transmission process.

[0007] 3. Integrated receiving and unfolding device: The receiving and unfolding functions are integrated into the lifting slider. The lifting slider is not only used during the goods receiving process. After the goods receiving is completed, the motor drives the lead screw to raise and lower the lifting slider to realize the receiving device's receiving and unfolding.

[0008] 4. A pneumatic emergency drive is provided. When the motor is damaged, the pneumatic motor can replace the motor to drive the lead screw and lift the slider to complete the cargo replenishment and loading / unloading functions.

[0009] 5. Further optimize the overall weight of the equipment while ensuring the same receiving capability.

[0010] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: an integrated retractable dry cargo resupply receiving device, including an integrated receiving column, a retractable device, a locking mechanism, and an electrical control system. A locking mechanism is installed on the top of the compartment. One end of the top of the compartment is hinged to the integrated receiving column via a pin at the top. A retractable device is connected between the integrated receiving column and the top of the compartment. The retractable device is used to store the integrated retractable dry cargo resupply receiving device in the top of the compartment when not in operation, and to fix it by the locking mechanism. When the integrated retractable dry cargo resupply receiving device is in operation, the locking mechanism is opened, and the integrated receiving column is controlled to rotate and lower around the pin at the top. After lowering, the integrated receiving column is fixed to the deck base by a pin. After fixing, the steel cable of the retractable device is released, and the motor inside the integrated column drives the ball screw to move the lifting slider along the column guide rail assembly to begin the resupply receiving operation.

[0011] Furthermore, the integrated receiving column includes a column body, a motor, a coupling, a ball screw assembly, a lifting slider, and a guide rail assembly. The lifting slider is connected to the column body via the guide rail assembly and to the motor via the ball screw assembly and coupling. The motor drives the ball screw in the ball screw assembly to move the lifting slider up and down along the column guide rail assembly to perform replenishment and receiving operations. When the motor fails, the pneumatic motor in the emergency drive device replaces the motor to drive the ball screw and move the lifting slider to complete the cargo replenishment and loading / unloading functions.

[0012] Furthermore, the lifting slider consists of a slider body, a lifting nut, a small roller group, a large roller group, and a side roller group. The lifting nut is installed at the center of the slider body and cooperates with the ball screw to realize the lifting of the slider body. The small roller group is located at the front of the slider body, and the large roller group is located at the rear of the slider body to realize the front and rear limit guidance of the slider body. The side roller group is located at the upper and lower ends of the slider body to realize the left and right limit guidance of the slider body.

[0013] Furthermore, the guide rail assembly consists of a guide rail and a guide rail base. The guide rail is fixedly installed in the middle of the inner side of the integrated receiving column through the guide rail base, making the reception of the entire integrated receiving column more uniform.

[0014] Furthermore, the emergency drive device consists of a pneumatic motor, a worm gear, and a worm. The worm gear is installed at the bottom of the lead screw, and the worm is located on the integrated receiving column. It is used to switch the drive mode when the motor fails during the receiving and replenishment process. The pneumatic motor drives the worm, which in turn drives the worm gear and the lead screw to move, so as to realize the transfer of goods and the raising and lowering of the integrated receiving column in emergency situations.

[0015] Furthermore, the retraction and deployment device includes a balancer assembly, a wire rope assembly, a guide pulley assembly, and a cable locking device. One end of the wire rope in the wire rope assembly is connected to the balancer assembly, and the other end is locked and fixed to the cable locking device through several guide pulleys. This is used to drive the retraction and deployment of the integrated receiving column by raising and lowering the lifting slider in the integrated receiving column, thereby completing the retraction and deployment action.

[0016] Furthermore, the guide pulley assembly consists of two sets of guide pulleys, each set comprising guide pulley one, guide pulley two, guide pulley three, guide pulley four, and guide pulley five. Guide pulley one and guide pulley two are fixed to the top of the compartment, guide pulley three and guide pulley four are fixed to the sides and rear of the integrated receiving column, and guide pulley five is fixed to the back of the lifting slider and moves up and down with the lifting slider.

[0017] Furthermore, the cable locking device is fixed to the back of the integrated receiving column via a connector. By fixing the end of the steel wire rope assembly, the entire integrated receiving column can be stored and lowered by the rise and fall of the lifting slider.

[0018] Furthermore, the electrical control system includes a filter distribution cabinet, a frequency converter control cabinet, a braking resistor cabinet, a column junction box, and a remote control operation box. The filter distribution cabinet provides power to the frequency converter control system and performs filtering. The frequency converter control cabinet provides main circuit power distribution control and controls the start and stop of the motor ramp according to the input control signal. It also adjusts the motor speed according to the operation, thereby controlling the lifting speed of goods. The column junction box is used to issue operation commands when operating at the machine. The remote control operation box is used to issue commands remotely to control the start and stop of the motor, and to perform cargo lifting, cable winding and unwinding, column retraction and lowering.

[0019] An operation control method for an integrated dry goods supply receiving device includes control methods for the collection operation and the release operation, wherein:

[0020] Control method for the storage operation: First, pull out the pin, pass the wire rope through the guide pulley on the slider and lock it through the cable locking device. Raise the slider to tighten the wire rope and maintain tension. Then, continue to raise the slider to store the integrated receiving column in place. After that, insert the locking pin through the locking mechanism to lock the integrated receiving column to the top of the cabin.

[0021] Control method for the lowering operation: First, pull out the locking pin through the locking mechanism, lower the lifting slider to lower the integrated receiving column. When the integrated receiving column is aligned with the pin hole on the deck by gravity, stop the lowering and raising. At this time, the steel wire rope should have a certain deflection and be in a stress-free state. Then, open the cable locking device to disconnect the steel wire rope from the lifting slider. Finally, insert the pin into the fixed pin hole and start the resupply operation.

[0022] The beneficial effects of this invention are:

[0023] 1. Integrated receiving and unfolding device: The receiving and unfolding functions are integrated into the lifting slider. The lifting slider is not only used during the goods receiving process. After the goods receiving is completed, the motor drives the lead screw to raise and lower the lifting slider to realize the receiving device's receiving and unfolding.

[0024] 2. A pneumatic emergency drive is provided. When the motor fails, the pneumatic motor can replace the motor to drive the lead screw and lift the slider to complete the cargo replenishment and loading / unloading functions.

[0025] 3. Optimize the structural design to reduce equipment weight.

[0026] By arranging large and small rollers and side rollers, the guide and limit of the lifting slider are concentrated on a single guide rail, achieving an integrated design of the slider, reducing the number of guide rails, and reducing the overall weight. Attached Figure Description

Detailed Implementation

[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0037] like Figure 1 As shown in Figure 2, the integrated dry cargo resupply receiving device of the present invention consists of two main parts: a mechanical part and an electrical control system. The mechanical part mainly consists of an integrated receiving column 12, a resupply / retrieval device 11, a locking mechanism 21, a long chain ring receiving head 22, a deck fixing base 13, a cableway traction winch 23, and an emergency drive device 36. The electrical control system includes a filter distribution cabinet, a frequency converter control cabinet, a braking resistor cabinet, a column junction box, and a remote control operation box.

[0038] The top of the compartment is equipped with a locking mechanism 21. One end of the top of the compartment is hinged to an integrated receiving column 12 via a pin at the top. A retraction device 11 connects the integrated receiving column 12 to the top of the compartment. The integrated receiving column 12 is equipped with a long chain ring receiving head 22. A cableway traction winch 23 is installed on the deck fixed base 13. An emergency drive device 36 is also installed on the integrated receiving column 12.

[0039] When not in operation, the integrated retractable dry cargo resupply receiving device is stored on the top of the compartment and secured by locking mechanism 21. During operation, locking mechanism 21 is opened, and the retractable device 11 controls the integrated receiving column 12 to rotate and lower around the pin at the top. After lowering, the integrated receiving column 12 is secured to the deck mounting base 13 by a pin. Once secured, the wire rope of the retractable device 11 is released, and the ball screw driven by the motor inside the integrated column moves the lifting slider along the column guide rail assembly to begin the resupply receiving operation.

[0040] The integrated receiving column 12 mainly consists of a column body 32, a motor 38, a coupling 37, a ball screw assembly 34, a lifting slider 35, a guide rail assembly 33, an emergency drive device 36, and a limit switch 31, etc. Figure 3As shown, the device uses a motor 38 to drive the ball screw in the ball screw assembly 34, which in turn drives the lifting slider 35 to move up and down along the column guide rail assembly 33 to begin the replenishment and receiving operation. When the motor 38 fails, the pneumatic motor in the emergency drive device 36 can replace the motor 38 to drive the ball screw and lift the slider 35 to complete the cargo replenishment and receiving functions.

[0041] like Figure 4 As shown in Figure 5, the lifting slider 35 consists of a slider body 42, a lifting nut 43, a small roller assembly 55, a large roller assembly 51, and a side roller assembly 41. The lifting nut 43 is installed at the center of the slider body 42 and cooperates with the lead screw to achieve the lifting and lowering of the slider body 42. The small roller assembly 55 is located at the front of the slider body 42, and the large roller assembly 51 is located at the rear of the slider body 42, providing front-to-back limiting and guiding for the slider body 42. The side roller assembly 41 is located at the upper and lower ends of the slider body 42, providing left-to-right limiting and guiding for the slider body 42.

[0042] By arranging large and small rollers and side rollers, the guide and limit of the lifting slider are concentrated on a single guide rail, achieving an integrated design of the slider, reducing the number of guide rails, and reducing the overall weight.

[0043] The guide rail assembly 33 consists of a guide rail 53 and a guide rail base 54. The guide rail 53 and the guide rail base 54 are the main load-bearing components, and they are fixedly installed in the middle of the inner side of the integrated receiving column 12, so that the entire integrated receiving column receives more evenly.

[0044] like Figure 6 As shown, the emergency drive device 36 consists of a pneumatic motor 64, a worm gear 62, and a worm 63. The worm gear 62 is mounted on the bottom of the lead screw 61, and the worm 63 is located on the integrated receiving column 12. When the motor 38 fails during the receiving and replenishment process, the drive mode will be switched immediately. The pneumatic motor 64 drives the worm, which in turn drives the worm gear 62 and the lead screw 61 to move, thereby realizing the transfer of goods and the raising and lowering of the integrated receiving column in emergency situations.

[0045] like Figure 7 As shown, the retraction / deployment device 11 mainly consists of a balancer assembly 72, a wire rope assembly 71, a guide pulley assembly, and a cable locking device 78. One end of the wire rope is connected to the balancer assembly 72, and the other end passes through several guide pulleys, with guide pulley 5 75 located on the slider. Finally, it is locked and fixed by the cable locking device 78. The retraction / deployment action is completed by using the lifting slider in the integrated receiving column to drive the integrated receiving column to retract or deploy.

[0046] The storage operation is as follows: After checking the equipment, pull out the pin, pass the wire rope through the guide pulley on the slider and lock it through the cable locking device. Raise the slider to tighten the wire rope and maintain tension, and check for any problems. Continue to raise the slider until the integrated receiving column is stored in place. Then, insert the locking pin through the locking mechanism to lock the integrated receiving column to the top of the cabin.

[0047] The lowering operation is as follows: After checking the equipment, pull out the locking pin through the locking mechanism. Lower the lifting slider to lower the integrated receiving column. Stop lowering when the integrated receiving column aligns with the pin hole on the deck under gravity. At this point, ensure the wire rope has a certain degree of deflection and is not under stress. Open the cable locking device to disconnect the wire rope from the lifting slider. Insert the pin into the fixed pin hole to begin the resupply operation.

[0048] The balancer assembly 72 can flexibly adjust the small-range length error of the wire ropes on both sides through two sets of wire rope assemblies, and can smoothly raise and lower the integrated receiving column even if there is a length error.

[0049] The guide pulley assembly consists of two sets of guide pulleys. Each set comprises guide pulley 1 (73), guide pulley 2 (74), guide pulley 3 (76), guide pulley 4 (77), and guide pulley 5 (75). Guide pulley 1 (73) and guide pulley 2 (74) are fixed to the top of the compartment. Guide pulley 3 (76) and guide pulley 4 (77) are fixed to the sides and rear of the integrated receiving column 12. Guide pulley 5 (75) is fixed to the back of the lifting slider 35 and moves up and down with the lifting slider 35.

[0050] The cable locking device 78 is fixed to the back of the integrated receiving column 12 via a connector. By fixing the end of the wire rope assembly 71, the integrated receiving column 12 can be retracted and lowered as a whole by raising and lowering the lifting slider 35.

[0051] like Figure 8 As shown, the electrical control system includes a filter distribution cabinet, a frequency converter control cabinet, a braking resistor cabinet, a column junction box, and a remote control operation box. The filter distribution cabinet provides power to the frequency converter control system and performs filtering. The frequency converter control cabinet provides main circuit power distribution control and can control the ramp start and stop of the motor according to the input control signal. It can also adjust the motor speed according to the operation, thereby controlling the lifting speed of goods. The column junction box is used to issue operation commands when operating at the machine. The remote control operation box is used to issue commands remotely to control the start and stop of the motor, and to perform tasks such as lifting and lowering goods, retracting and extending cables, and retracting and lowering the column.
