Description

Technical Field

[0001] The present invention relates to the technical field of ship engineering, and particularly to a ship liquid cargo conveying device and an installation and use method thereof. Background Art

[0002] The conveyance of liquid cargo (such as fuel oil, fresh water, chemicals, etc.) between ships or between a ship and a dock is a common operation. Such conveyance usually requires connecting the ship and the receiving device through a flexible conveyance pipe.

[0003] In order to span the distance between the ship and the dock and support the weight of the conveyance pipe, one or more cross cables (such as steel cables) are usually erected. The cross cables are used to hang the conveyance pipe and provide support for it.

[0004] However, in a marine environment, a ship is affected by various factors such as wind, waves, and the change in draft caused by loading and unloading cargo, resulting in continuous relative movement relative to the dock, including rolling, pitching, heaving, etc. This relative movement causes the distance and relative position between the ship and the dock to constantly change.

[0005] If the length of the cross cable for supporting the conveyance pipe is fixed or adjusted untimely and inaccurately, this relative movement will cause the cross cable to sometimes bear excessive tension and sometimes become too slack. Excessive tension may damage the cross cable itself, the winch, and the receiving components on the dock, posing a safety hazard. And if the cross cable is too slack, it will cause the conveyance pipe to sag excessively, possibly touch the water surface, become kinked, or collide with other objects and be damaged, which also affects the safety and efficiency of the conveyance operation.

[0052] The following combines the drawings and embodiments to further describe in detail the specific implementation manners of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

Therefore, it cannot be understood as a limitation of the present invention. For those of ordinary skill in the art, the specific meanings of these terms in the present invention can be understood according to specific circumstances.

[0054] In the description of the present invention, the terms "provided with", "set", "connected", "placed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there is an internal connection between two devices, elements or components.

[0055] In addition, terms such as "first", "second", etc. are mainly used to distinguish different devices, components or parts (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, components or parts. Unless otherwise specified, the meaning of "a plurality" is two or more.

[0056] The technical solution of the present invention will be further described below in conjunction with embodiments and drawings.

[0057] As Figure 1-7 shown, the first aspect of the embodiment of the present invention provides a ship liquid cargo conveying device, including:

[0058] A receiving assembly 1, the receiving assembly 1 is used to be installed on a dock 13;

[0059] A winch 2, the winch 2 is used to be installed on a supply ship 12;

[0060] A cross cable 3, the first end of the cross cable 3 is fixedly connected to the winch 2, and the cross cable 3 can be wound onto the winch 2;

[0061] A compensation assembly 4, the compensation assembly 4 can be installed on the supply ship 12, the second end of the cross cable 3 passes through the compensation assembly 4 and is detachably connected to the receiving assembly 1, and the compensation assembly 4 is used to release or accommodate the cross cable 3 to compensate for the relative movement between the supply ship 12 and the dock 13;

[0062] A conveying pipe 5, the conveying pipe 5 is suspended on the cross cable 3 and is used to convey liquid cargo.

[0063] Based on the above technical solution, by providing a compensation assembly 4 on the supply ship 12 that can release or accommodate the cross cable 3, the adverse effect of the relative movement between the ship and the dock 13 on the tension of the cross cable 3 is effectively overcome, and the tension of the cross cable 3 can be maintained within a relatively stable range, which not only avoids safety accidents such as the breakage of the cross cable 3, damage to the winch 2 or the receiving assembly 1 caused by excessive tension, but also prevents the conveying pipe 5 from sagging excessively, touching the water surface or obstacles and being damaged due to too small tension, thereby enhancing the conveying safety and stability.

[0064] Preferably, the compensation assembly 4 includes a first compensation plate 401, a second compensation plate 402 and a compensation driving member 403. The second compensation plate 402 is used to be installed on the supply ship 12. The first compensation plate 401 and the second compensation plate 402 are arranged at intervals in the up-down direction. The compensation driving member 403 is arranged between the first compensation plate 401 and the second compensation plate 402 and is used to drive the first compensation plate 401 to move up and down relative to the second compensation plate 402. A plurality of first compensation guide wheels 404 are rotatably arranged on the first compensation plate 401, and the plurality of first compensation guide wheels 404 are arranged at intervals in the horizontal direction. A plurality of second compensation guide wheels 405 are rotatably arranged on the second compensation plate 402, and the plurality of second compensation guide wheels 405 are arranged at intervals in the horizontal direction. The cross cable 3 reciprocally winds between at least one first compensation guide wheel 404 of the first compensation plate 401 and at least one second compensation guide wheel 405 of the second compensation plate 402.

[0065] Specifically, the compensation driving member 403 is an oil cylinder or a cylinder.

[0066] The cross cable 3 reciprocally winds multiple times between the plurality of first compensation guide wheels 404 of the first compensation plate 401 and the plurality of second compensation guide wheels 405 of the second compensation plate 402. When the compensation driving member 403 drives the first compensation plate 401 to generate a displacement ΔL relative to the second compensation plate 402, the compensation amount of the cross cable 3 is approximately N*ΔL, where N is the number of winding segments of the cross cable 3 between the first compensation plate 401 and the second compensation plate 402. The compensation driving member 403 only needs to generate a small stroke to greatly adjust the effective length of the cross cable 3 between the dock 13 and the supply ship 12. At the same time, the multi-segment load-bearing structure of the compensation assembly 4 can be borne by the plurality of first compensation guide wheels 404 and the plurality of second compensation guide wheels 405 to smoothly absorb and buffer the sudden change of the tension of the cross cable 3.

[0067] More preferably, when observed in the up-down direction, the plurality of first compensation guide wheels 404 and the plurality of second compensation guide wheels 405 are arranged staggered with each other in the horizontal direction.

[0068] The plurality of first compensation guide wheels 404 and the plurality of second compensation guide wheels 405 are arranged staggered with each other in the horizontal direction, so that the cross cable 3 extends in the up-down direction between the first compensation plate 401 and the second compensation plate 402. The tension loads exerted by the cross cable 3 on the first compensation guide wheels 404 and the second compensation guide wheels 405 are almost completely in the up-down direction (ignoring friction and dynamic effects), that is, the loads of the cross cable 3 borne by the first compensation guide wheels 404 and the second compensation guide wheels 405 are mainly radial loads, which simplifies the force-bearing mode of the bearings of the first compensation guide wheels 404 and the second compensation guide wheels 405 and prolongs the service life of the first compensation guide wheels 404 and the second compensation guide wheels 405.

[0069] More preferably, the ship liquid cargo conveying device further includes a sensing assembly 6, which is located on the side of the compensation assembly 4 away from the winch 2. The sensing assembly 6 includes at least one sensing unit 601. The sensing unit 601 includes a sensing support 6011, a sensing guide wheel 6012 and a force sensor. The sensing guide wheel 6012 is rotatably arranged on the sensing support 6011, the cross cable 3 is wound around the sensing guide wheel 6012, and the force sensor is installed on the sensing support 6011 for measuring the force exerted on the sensing support 6011 by the cross cable 3 through the sensing guide wheel 6012. The sensing support 6011 is used for fixedly installing on the supply ship 12, and the force sensor is electrically connected to the compensation driving member 403 and the winch 2.

[0070] Specifically, it further includes a control assembly, and the control assembly is electrically connected to the force sensor, the compensation driving member 403 and the winch 2.

[0071] The force sensor measures the force exerted by the cross cable 3 on the sensing guide wheel 6012, so as to obtain the actual tension magnitude of the cross cable 3 between the dock 13 and the supply ship 12. The force sensor feeds back the measured tension signal to the compensation driving member 403 and the winch 2 through electrical connection, compares the actual tension with the preset target tension. If a deviation is detected between the two, the control assembly can adjust the compensation driving member 403 according to the deviation magnitude, or operate the winch 2 to wind or unwind the cross cable 3 when the stroke of the compensation driving member 403 reaches the limit or a large adjustment is required, which can accurately and quickly respond to the relative movement and external interference between the supply ship 12 and the dock 13, and stabilize the tension of the cross cable 3 within an ideal range, greatly improving the accuracy of tension compensation and the dynamic response ability of the system.

[0072] More preferably, the ship liquid cargo conveying device further includes a gantry 7 and a position driving member. The gantry 7 is used for installing on the supply ship 12. A slide rail extending in the vertical direction is provided on the gantry 7. A slider 8 is slidably arranged on the slide rail. The power output end of the position driving member is connected to the slider 8 for driving the slider 8 to slide. The sensing assembly 6 includes two sensing units 601 spaced apart in the vertical direction. The upper sensing unit 601 is installed on the slider 8, and the lower sensing unit 601 is used for fixedly installing on the supply ship 12.

[0073] Specifically, the position driving member includes a driving motor and a lead screw. The lead screw is rotatably arranged in the slide rail and extends in the vertical direction. The power output end of the driving motor is connected to the lead screw for driving the lead screw to rotate. A threaded hole is provided on the slider 8, and the slider 8 is engaged with the lead screw through the threaded hole.

[0074] By driving the slider 8 to move up and down through the position driving member, the height of the sensing unit 601 located on the upper side can be adjusted, enabling the ship liquid cargo conveying device to flexibly adapt to the situation where there is a large height difference between the receiving positions of the supply ship 12 and the dock 13. Before the start of the conveying operation, the outgoing height of the cross cable 3 is adjusted to ensure that the cross cable 3 and the suspended conveying pipe 5 have a relatively reasonable geometric shape, avoiding problems such as improper tension or poor shape of the conveying pipe 5 caused by too large or too small height differences. At the same time, it can make the conveying pipe 5 have a certain inclination from the supply ship 12 to the dock 13, using gravity to assist the flow of liquid cargo, reducing the flow resistance, which helps to reduce the pumping energy consumption of the pumping system of the supply ship 12 and improve the conveying efficiency.

[0075] The two sensing units 601 form an information source redundancy. If one of them fails, the system can still rely on the data of the other sensing unit 601 to continue operating, improving the reliability and fault tolerance of the sensing component 6.

[0076] Preferably, the ship liquid cargo conveying device further includes a plurality of first pulleys 9 and a supporting portion 10 movably arranged on the first pulleys 9. The first pulleys 9 are movably arranged on the cross cable 3. The supporting portion 10 is an arc-shaped hollow tube body, and the conveying pipe 5 passes through the supporting portion 10.

[0077] Specifically, the cross-section of the supporting portion 10 is a rectangular cross-section, allowing the conveying pipe 5 to swing laterally within the supporting portion 10, and the first pulley 9 can slide by the pulling of the cable.

[0078] The plurality of first pulleys 9 are slidably distributed along the cross cable 3, which can disperse the weight of the conveying pipe 5 and the liquid cargo to multiple support points, rather than relying only on the two ends for suspension, significantly reducing the sag amount of the conveying pipe 5 between the two support points. The arc-shaped supporting portion 10 provides a supporting surface that conforms to its shape for the conveying pipe 5, avoiding the risk of wear of the conveying pipe 5 caused by local stress concentration, protecting the structure of the conveying pipe 5, helping to extend its service life, and preventing an increase in flow resistance or damage to the pipe wall caused by excessive bending; designing the internal cross-section of the supporting portion 10 as a rectangle, in actual operation, the conveying pipe 5 will be affected by factors such as wind force, ship sway caused by waves, liquid flow in the pipe, and even its own slight torsion, resulting in lateral swing. The rectangular cross-section provides an additional gap on both sides of the conveying pipe 5, enabling the conveying pipe 5 to move freely within this gap without rigid contact or severe friction with the side wall of the supporting portion 10. It avoids stress concentration and pipe wall wear caused by excessive restraint, and allows the conveying pipe 5 to better adapt to the dynamic environment, reducing the damage risk and improving the flexibility and reliability of the conveying operation.

[0079] More preferably, the ship liquid cargo conveying device further includes at least one second pulley 11. The receiving assembly 1 includes a base 101, a span wire fixing part 102 and a liquid cargo receiving pipe 103. The base 101 is used to be installed on the dock 13. The span wire fixing part 102 is movably arranged on the base 101. The second end of the span wire 3 is detachably installed on the span wire fixing part 102. The liquid cargo receiving pipe 103 is arranged on the span wire fixing part 102. The end of the conveying pipe 5 is provided with a conveying joint 501. The second pulley 11 is movably arranged on the span wire 3. The second pulley 11 is connected to the conveying joint 501. The conveying joint 501 is detachably installed with the liquid cargo receiving pipe 103.

[0080] Specifically, the span wire fixing part 102 is a hook for hooking the second end of the span wire 3.

[0081] The second pulley 11 is used to support and guide the conveying joint 501 of the conveying pipe 5. When laying out the conveying pipe 5, the second pulley 11 moves along the span wire 3, precisely guiding the conveying joint 501 to the liquid cargo receiving pipe 103 at the dock 13, simplifying the process of aligning and connecting the possibly heavy and difficult-to-maneuver conveying joint 501 to the liquid cargo receiving pipe 103, improving the accuracy, convenience and safety of the docking operation. The operator does not need to bear the full weight of the end of the conveying pipe 5 or make large-scale position adjustments.

[0082] The second aspect of the present invention provides an installation and use method for installing the ship liquid cargo conveying device onto the dock 13 and the supply ship 12 and performing liquid cargo replenishment operations, including the following steps:

[0083] S1. Install the winch 2, the compensation assembly 4, the sensing assembly 6, and the gantry 7 at the predetermined positions of the supply ship 12, install the receiving assembly 1 at the predetermined position of the dock 13, connect the first end of the span wire 3 to the winch 2, and wind the span wire 3 around the compensation assembly 4 and the sensing assembly 6;

[0084] S2. Transmit the second end of the span wire 3 from the supply ship 12 to the dock 13 and install it on the span wire fixing part 102;

[0085] S3. Operate the winch 2 to reel in the span wire 3, and establish and maintain the preset working tension of the span wire 3 through the compensation assembly 4 and the sensing assembly 6;

[0086] S4. Release the second pulley 11 and the first pulley 9 in sequence, lay out the conveying pipe 5 along the span wire 3 to the dock 13, and dock and connect the conveying joint 501 with the liquid cargo receiving pipe 103. After docking, perform liquid cargo transportation;

[0087] S5. During the transportation process, automatically adjust the effective length of the span wire 3 through the compensation assembly 4 and the sensing assembly 6 to compensate for the relative movement between the supply ship 12 and the dock 13;

[0088] After the conveying is completed, remove the conveying joint 501 from the liquid cargo receiving pipe 103, and recover the cross cable 3 through the winch 2.

[0089] In a specific embodiment, in S2, connect the middle part of the cross cable 3 to the middle part of the lead rope 14. The operator on the supply ship 12 uses a rope shooting gun to shoot one end of the lead rope 14 to the dock 13. The operator on the dock 13 and the operator on the supply ship 12 tighten the lead rope 14 at the same time. At this time, the operator on the dock 13 slowly pulls the lead rope 14, and at the same time, the operator on the supply ship 12 slowly releases the lead rope 14 until the second end of the cross cable 3 is connected to the cross cable fixing part 102.

[0090] Connect the second end of the cross cable 3 to the middle part of the lead rope 14, and the operators located on the supply ship 12 and the dock 13 tighten the lead rope 14 at the same time. The lead rope 14 itself is taut between the supply ship 12 and the dock 13. The operator on the dock 13 pulls one end of the lead rope 14, and the operator on the supply ship 12 correspondingly releases the other end of the lead rope 14, so that the second end of the cross cable 3 can be stably and controllably towed across the sea surface along a relatively stable path of the lead rope 14, and it is not easy to sag excessively, touch the water or swing greatly.

[0091] More preferably,

[0092] In S4, before the conveying joint 501 is docked with the liquid cargo receiving pipe 103, block the conveying joint 501 for a sealing test.

[0093] Specifically, a flange is provided on the conveying joint 501. Before the conveying joint 501 is docked with the liquid cargo receiving pipe 103, use a sealing cover to dock and seal with the flange. At this time, input a test medium, such as water or inert gas, etc., into the conveying pipe 5 through the pumping system of the supply ship 12 until the conveying pipe 5 is filled, keep the pressure of the conveying pipe 5, and observe whether there is any leakage at the entire length of the conveying pipe 5, the connection of the conveying joint 501 and the sealing cover. If there is no obvious leakage, observe whether the value on the hydraulic sensor or pneumatic sensor that monitors the pressure in the conveying pipe 5 in the pumping system drops. If there is an obvious drop, replace the conveying pipe 5 in time and conduct the sealing test again.

[0094] More preferably,

[0095] In S5, if the force sensor monitors that the tension of the cross cable 3 exceeds the preset range or the compensation driving part 403 reaches the stroke limit, automatically control the winch 2 to wind up or release the cross cable 3.

[0096] The compensation assembly 4 is mainly used to quickly respond to and compensate for relatively fast relative movements within a certain range. However, when the relative movement amplitude between the ship and the shore is too large (exceeding the stroke limit of the compensation drive 403) or the accumulated displacement causes the tension to continuously deviate from the normal range, the compensation assembly 4 alone can no longer effectively adjust. At this time, the winch 2 is called to directly take in and release the overall length of the cross cable 3 for a larger range of adjustment, adding a secondary compensation mechanism, greatly expanding its safe movement range, effectively preventing the phenomenon of the cross cable 3 being broken due to excessive tension caused by the compensation assembly 4 reaching the limit, and ensuring the safety of the conveying operation and the reliability of the system.

[0097] In summary, the embodiment of the present invention provides a ship liquid cargo conveying device and its installation and use method. By setting a compensation assembly 4 on the supply ship 12 that can release or receive the cross cable 3, it effectively overcomes the adverse effects of the relative movement between the ship and the dock 13 on the tension of the cross cable 3, and can maintain the tension of the cross cable 3 within a relatively stable range. It not only avoids safety accidents such as the breakage of the cross cable 3, the damage of the winch 2 or the receiving assembly 1 that may be caused by excessive tension, but also prevents the conveying pipe 5 from sagging excessively, touching the water surface or obstacles and being damaged due to too small tension, thereby enhancing the safety and stability of the conveying.

[0098] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
