Description

Technical Field

[0001] This invention relates to the field of marine equipment technology, and more specifically, to a semi-submersible slipway ship transfer device and its usage method. Background Technology

[0002] Currently, the main methods for launching ships are: launching via slipway, direct launching from the dry dock, and launching via airbags. Slipway launching is the primary method used in small and medium-sized shipyards, and safety is paramount for shipyards during launching. In semi-submersible slipways, two ships are sometimes placed one in front of the other, resulting in the latter ship having a longer sliding distance on the slipway and a greater distance from the lock gate. If launched directly from the original position, the ship's sliding speed would be relatively high, causing the ball bearing mechanism to bounce up, resulting in a longer stroke on the water and potentially leading to unpredictable consequences.

Detailed Implementation

[0036] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and by way of embodiments. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0037] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, B exists alone, and A and B exist simultaneously. The term " / and" in this article describes another type of relationship between related objects, indicating that two relationships can exist. For example, A / and B can mean: A exists alone, and A and B exist alone. In addition, the character " / " in this article generally indicates that the related objects before and after it are in an "or" relationship.

[0038] according to Figures 1-6 As shown, a semi-submersible ship-moving device and its method of use include a sliding support, segmented blocking components, and a slow-release component. Both the sliding support and the slow-release component are mounted on the ground, and the slow-release component is connected to the ship to be moved. The segmented blocking components are mounted on the sliding support. The sliding support includes a support platform 1, a ball bearing spacer, and a sliding seat 2. The support platform 1 is mounted on the ground, and both the ball bearing spacer and the sliding seat 2 are mounted on the support platform 1.

[0039] The support platform 1 is rectangular and constructed of reinforced concrete. One end of the support platform 1 is on the shore, and the other end extends below the water surface. A first slide rail 3 is provided on one side of the support platform 1, and a second slide rail 4 is provided on the other side, parallel to the first slide rail 3. Multiple blocking grooves 5 are provided on the support platform 1 between the first slide rail 3 and one side of the support platform 1, and between the second slide rail 4 and the other side of the support platform 1. These blocking grooves 5 are distributed longitudinally along the support platform 1 at predetermined intervals. Alternatively, the spacing between the blocking grooves 5 is one meter. Alternatively, two support platforms 1 are provided, parallel to each other, and the spacing between the two support platforms 1 meets the width requirements of the towed vessel.

[0040] The ball bearing spacer includes a ball bearing spacer plate, a first ball 6, and a ball bearing lubricant (not shown in the figure). Both the ball bearing spacer plate and the ball bearing lubricant are mounted on the support platform 1. The first ball 6 is mounted on the ball bearing spacer plate. The ball bearing spacer plate is rectangular in shape and has ball bearing spacer grooves. These grooves are spherical in shape, and an oil passage groove is formed on the spherical surface of each groove. The oil passage groove communicates with the ball bearing spacer groove, allowing lubricating oil flowing through it to be adsorbed by the first ball 6 and enter the ball bearing spacer groove, thus maintaining lubrication between the first ball 6 and the ball bearing spacer groove. Multiple ball bearing spacer grooves are arranged in a matrix on the ball bearing spacer plate, and each column of grooves is connected by an oil passage hole. Specifically, the oil passage hole communicates with the oil passage groove. The oil passage flow hole is connected to both ends of the ball bearing spacer plate, and the axial line of the oil passage flow hole is parallel to the longitudinal line of the ball bearing spacer plate. Multiple first balls 6 are sequentially fitted into multiple ball bearing spacer grooves, and the first balls 6 are capable of rolling within the ball bearing spacer grooves.

[0041] The ball bearing lubrication system includes an upper lubrication reservoir, a lower lubrication reservoir, and a lubricating oil pump, all of which are mounted on the support platform 1. The upper lubrication reservoir is located at one end of the support platform 1 and is connected to one end of each of the multiple oil passage openings via flow valves. This allows lubricating oil in the upper lubrication reservoir to flow through the flow valves into one end of the oil passage openings under gravity. A small portion of the lubricating oil then rolls and adheres to the ball bearing grooves through the oil passage openings, the oil passage grooves, and the first ball bearing 6. The remaining lubricating oil flows through the other end of the oil passage openings into the lower lubrication reservoir. The lower lubrication reservoir is located at the other end of the support platform 1 and is connected to the other end of each of the multiple oil passage openings. The lubricating oil pump inlet is connected to the lower lubrication reservoir, and the lubricating oil pump outlet is connected to the upper lubrication reservoir, thereby pumping the lubricating oil from the lower lubrication reservoir into the upper lubrication reservoir. Two sets of ball bearing spacers are provided, each set corresponding to one of the two support platforms 1.

[0042] The sliding seat 2 is rectangular in shape. The sliding wheels on the sliding seat 2 are respectively fastened to the first slide rail 3 and the second slide rail 4 on the two support platforms 1, thereby allowing the vessel fixed on the sliding seat 2 to move into the water along the first slide rail 3 and the second slide rail 4. The sliding seat 2 is equipped with a buffer component, which includes a buffer plate 7 and a buffer fastening groove 8. The buffer plate 7 is rectangular in shape and is fixedly mounted on one side of the sliding seat. The length of the buffer plate 7 is not less than the width of the support platform 1. Alternatively, the buffer plate 7 can be a wooden board or a hard rubber board. The buffer fastening groove 8 is rectangular in shape. A second ball bearing is embedded in the inner side of the bottom of the buffer fastening groove 8, which reduces the friction between the buffer fastening groove 8 and the telescopic blocking block 10. The outer side of the bottom of the buffer fastening groove 8 is fixedly mounted on one end of the buffer plate 7, and the buffer fastening groove 8 is symmetrical to the blocking groove 5, so that the buffer fastening groove 8 abuts against the telescopic blocking block 10. Two buffer fastening slots 8 are provided, each located at one end of the buffer plate 7, and each corresponding to one of the two columns of blocking slots 5. Two buffer components are provided, each corresponding to one of the two support platforms 1.

[0043] The segmented blocking component includes a telescopic blocking component, a blocking power component, and a blocking lubrication component, all of which are mounted on the support platform 1. The telescopic blocking component includes a telescopic blocking seat 9, a telescopic blocking block 10, and a relay telescopic component. The telescopic blocking seat 9 is mounted on the support platform 1, and the telescopic blocking block 10 and the relay telescopic component are both mounted on the telescopic blocking seat 9. The telescopic blocking seat 9 is rectangular, and the telescopic blocking block 10 has the same dimensions as the blocking groove 5. A telescopic blocking groove 23, shaped like an I-beam, is provided on the top surface of the telescopic blocking seat 9. Alternatively, a sealing strip is provided at the opening of the telescopic blocking groove 23 to increase the sealing between the telescopic blocking groove 23 and the telescopic blocking block 10, preventing lubricating oil from spraying out of the opening of the telescopic blocking groove 23.

[0044] The telescopic blocking block 10 is an I-beam, and its length is less than the depth of the telescopic blocking groove 23. One end of the telescopic blocking block 10 is inserted into the telescopic blocking groove 23, allowing it to move up and down within the groove. The relay telescopic component includes a blocking relay gear 11 and a blocking relay tube 12. The blocking relay gear 11 is mounted on the telescopic blocking seat 9, and the blocking relay tube 12 is mounted on the blocking relay gear 11. The blocking relay gear 11 is embedded in the relay cavity within the telescopic blocking seat 9, and it meshes with the teeth on the telescopic blocking block 10. Specifically, the relay cavity communicates with the telescopic blocking groove 23. One end of the blocking relay tube 12 is fixedly mounted on the blocking relay gear 11, and its axis coincides with the axis of the blocking relay gear 11. The other end of the blocking relay tube 12 passes through the telescopic blocking seat 9, allowing it to rotate on the seat. The telescopic blocking members are correspondingly embedded in the blocking grooves 5.

[0045] The blocking power component includes a blocking motor and a blocking relay rod. The blocking motor is detachably mounted on the side of the support platform 1. One end of the blocking relay rod is fixedly connected to the rotating shaft of the blocking motor, and the other end of the blocking relay rod passes through a pre-reserved relay through hole 13 on the support platform 1 and is inserted into the other end of the blocking relay tube 12. A slider on the side wall of the blocking relay rod engages with a groove on the inner wall of the blocking relay tube 12. When the blocking motor drives the blocking relay rod to rotate, the slider and the groove drive the blocking relay tube 12 to rotate. The rotating blocking relay tube 12, through the blocking relay gear 11, drives the telescopic blocking block 10 to move up and down within the telescopic blocking groove 23.

[0046] The blocking lubrication component includes a blocking lubrication oil tank and a lubrication relay pipe. The blocking lubrication oil tank is detachably installed on the side of the support platform 1. One end of the lubrication relay pipe is connected to the bottom of the blocking lubrication oil tank, and the other end of the lubrication relay pipe passes through a first lubrication relay through hole 14 reserved on the side of the support platform 1 and is connected to a second lubrication relay through hole 15 reserved on the telescopic blocking seat 9, so that the blocking lubrication oil tank communicates with the bottom end of the telescopic blocking groove 23 through the lubrication relay pipe and the second lubrication relay through hole 15. When the telescopic blocking block 10 moves into the telescopic blocking groove 23, it squeezes lubricating oil to flow into the blocking lubrication oil tank. When the telescopic blocking block 10 moves out of the telescopic blocking groove 23, it draws lubricating oil from the blocking lubrication oil tank into the telescopic blocking groove 23, providing lubrication for the telescopic blocking block 10 and the telescopic blocking groove 23.

[0047] Multiple sets of segmented blocking components are provided. According to the tonnage of the ship being moved, the multiple sets of segmented blocking components are installed into the blocking grooves at predetermined intervals to prevent the sliding seat 2 from moving downward.

[0048] The slow release mechanism includes a release fixing component and a pulley retraction component. The release fixing component is located on the ground, and the pulley retraction component is connected to the release fixing component. The release fixing component includes a release fixing seat 16 and a steering wheel 17. The release fixing seat 16 is firmly buried in the ground to resist the pulling force of the ship sliding downhill, and the steering wheel 17 is located at the top of the release fixing seat 16. The pulley retraction component includes a pulley block, a steel cable 18, a steel wire rope 19, and a winch 20. The movable pulley block 22 of the pulley block is fixedly connected to the top of the release fixing seat 16 via the steel cable 18. The movable pulley block 22 of the pulley block is connected to two eye plates of the ship to be moved via steel cables. The eye plates are welded to the bottom of the ship to be moved, and the two eye plates are symmetrically distributed. One end of the steel wire rope 19 is wrapped around the movable pulley block 22 and the stationary pulley block 21 and then fixedly connected to the stationary pulley block 21. The other end of the steel wire rope 19 is wound and connected to the winch 20.

[0049] The specific steps for using the semi-submersible slipway ship transfer device are as follows:

[0050] 1) Based on the tonnage of the vessel to be moved, determine the spacing of the segmented blocking components along the longitudinal direction of the support platform 1;

[0051] 2) Insert multiple telescopic blocking components into the blocking grooves with corresponding spacing, and assemble the blocking power component and the blocking lubrication component accordingly, while raising the telescopic blocking block 10 to its highest position;

[0052] 3) The movable pulley block 22 is connected to the two eye plates of the vessel to be moved by steel cables. The winch 20 slowly moves the vessel to be moved, which is fixed on the sliding seat 2, downward along the first slide rail 3 and the second slide rail 4 through the steel wire rope 19 and the pulley block.

[0053] 4) Stop releasing the rope when the sliding seat 2 slides down to the nearest first telescopic blocking block 10;

[0054] 5) Start the blocking motor to retract the telescopic blocking block 10 into the telescopic blocking groove 23;

[0055] 6) When the winding machine starts releasing the rope and the sliding seat 2 slides down to the nearest second telescopic blocking block 10, stop releasing the rope;
