Description

Technical Field

[0001] This invention belongs to the field of ship jacking technology, specifically relating to a slotted column type ship jacking connection device and a ship. Background Technology

[0002] Due to the limitations imposed by the standard loading draft of 4.3 meters on the Three Gorges Dam locks and the scale of shallows and winding channels in the middle reaches of the Yangtze River, the loading capacity of a single ship cannot exceed 10,000 tons on these sections of the river. This greatly restricts the shipping efficiency of the Three Gorges Reservoir area and the deep-water section downstream of the dam. If two or more ships with a standard loading draft of 4.3 meters are linked together to form a fleet, the transport capacity can reach 10,000 tons in a single trip, and they can pass through the locks smoothly.

[0003] In the prior art, a fleet of multiple ships connected in series typically consists of a tugboat that provides the main thrust and one or more cargo ships with similar draft and deadweight. They are connected in a longitudinal queue, with the bow of the last ship touching the stern of the first ship. The adjacent ships are connected by a jacking connection device, and then the tugboat at the stern provides power to push the entire fleet along the waterway, thereby reducing the overall energy consumption of the fleet.

[0004] In existing technologies, the jacking connection device is usually a cable or a direct rigid connection between adjacent ships. When the fleet moves forward, the following ships only need to push against the preceding ship to push it forward, and the cable is relatively unstressed. However, when the fleet needs to move backward, the following ships need to pull the preceding ship backward via the cable. The cable is difficult to withstand the tension on the heavier preceding ship, or when the fleet turns, the cable on one side of the fleet will also be subjected to a large tension, making it very easy to be damaged. While the rigid connection method can allow adjacent ships to withstand greater tension or thrust, due to the large size and mass of the ships, their momentum is also large, and it is difficult for the connected ships to respond synchronously to changes in their motion. In addition, affected by the wind and waves in the navigation waters, there are many forms of relative motion between the ships in the tandem fleet, and the rigid connection cannot meet the relative motion requirements between adjacent ships.

[0005] Furthermore, existing technologies propose using movable jacking connection devices to connect adjacent vessels, facilitating relative movement between them. For example, patent CN200510024190.1 discloses a jacking vessel articulation device, which uses universal bearings to achieve rotational connection between adjacent vessels in three dimensions, thereby enabling multi-directional relative movement between them. It can also withstand thrust or pull forces between adjacent vessels to a certain extent. However, when the relative speed of adjacent vessels changes, the rate of change of momentum Δ(mv) / Δt increases. Especially when the relative motion state between vessels changes abruptly, the short duration and huge force can easily damage the bearings at the connection point, or even cause an accident.

[0006] Another major problem with tandem fleets is that when one of the vessels capsizes due to a marine accident (such as running aground and taking on water), it may affect or even capsize the adjacent vessels connected to it. Therefore, how to make the connecting device both meet the connection needs of adjacent vessels and allow for rapid disconnection in the event of an accident has become an urgent technical problem to be solved. Summary of the Invention

[0007] In view of the shortcomings of the prior art, the present invention provides a channel-type ship jacking connection device and a ship, so as to solve the problem that the connection device can meet the connection needs of adjacent ships and the requirement that the connection can be quickly disconnected in case of an accident.

[0008] According to embodiments of the present invention, the present invention adopts the following technical solution:

[0009] A slotted column type marine jacking connection device includes an X-axis rotating assembly, a Y-axis rotating assembly, and a Z-axis rotating assembly. The X-axis rotating assembly includes an X-axis mounting base and an X-axis column rotatably connected to the X-axis mounting base, with the rotation axis of the X-axis column along the ship's direction of travel. The Y-axis rotating assembly includes a Y-axis mounting base, a Y-axis mounting groove on the Y-axis mounting base, and a Y-axis column with a clearance fit to the Y-axis mounting groove, with the rotation axis of the Y-axis column along the vertical direction. The Z-axis rotating assembly connects the X-axis rotating assembly and the Y-axis rotating assembly. The Z-axis rotating assembly includes a Z-axis mounting base, a Z-axis mounting groove on the Z-axis mounting base, and a Z-axis column with a clearance fit to the Z-axis mounting groove, with the rotation axis of the Z-axis column along the ship's width direction. The Z-axis mounting base has a Z-axis opening for the Z-axis column to be engaged or disengaged radially from the Z-axis mounting base, and the side wall of the Z-axis column has a Z-axis notch axially for disengaging from the Z-axis mounting base.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. In this design, the rotation of the X-axis column relative to the X-axis mounting base, the rotation of the Y-axis column relative to the Y-axis mounting base, and the rotation of the Z-axis column relative to the Z-axis mounting base enable multi-directional relative movement (including convoy turning, pitching, rolling, etc.) between adjacent vessels. This accommodates various water conditions and is suitable for connecting convoys in inland waterways and coastal areas, as well as for push-propelled navigation. Furthermore, the slotted column connection—with the Y-axis column installed in the Y-axis mounting slot and the Z-axis column installed in the Z-axis mounting slot—provides a larger contact area between the columns compared to bearing connections, allowing for better resistance to thrust or tension and a more reliable connection.

[0012] 2. During normal navigation, the ship is affected by wind and waves, resulting in small-angle pitching and trimming motions at the bow and stern. At this time, the Z-axis column rotates slightly relative to the Z-axis mounting base, and is obstructed by the Z-axis opening, becoming stuck in the Z-axis mounting slot. However, when the ship runs aground and takes on water, the resulting large-angle trim causes the Z-axis column to rotate significantly relative to the Z-axis mounting base. Due to the Z-axis notch, the width of the Z-axis column facing the Z-axis opening can change during rotation. When the width of the Z-axis column facing the Z-axis opening is less than the width of the Z-axis opening, it can disengage through the Z-axis opening.

[0013] In this scheme, when a ship experiences a large angle of trim, and the Z-axis column rotates at a large angle relative to the Z-axis mounting seat, the Z-axis column can automatically detach from the Z-axis mounting seat through the Z-axis opening, thus disconnecting adjacent ships and preventing the entire fleet from being affected. This scheme is suitable for emergency avoidance.

[0014] Furthermore, the length of the Y-direction mounting groove is greater than the axial length of the Y-direction column; the length of the Z-direction mounting groove is greater than the axial length of the Z-direction column.

[0015] Beneficial effects: The Y-axis column can slide relative to the Y-axis mounting base along its axis, and the Z-axis column can slide relative to the Z-axis mounting base along its axis, thus meeting the requirements for vertical heave and lateral translation between adjacent vessels. In particular, when adjacent vessels have different loads and drafts, their heights above the waterline will differ. The sliding of the Y-axis column relative to the Y-axis mounting base along its axis can accommodate connections between vessels at different water levels.

[0016] Furthermore, the Y-axis column includes a column base, a column core rotatably connected to the column base, and a driving component for driving the column core to rotate; the Y-axis mounting base has a Y-axis opening for the column core to be engaged or disengaged from the Y-axis mounting base in its radial direction, and the side wall of the column core has a Y-axis notch for disengaging from the Y-axis mounting base in its axial direction.

[0017] Beneficial Effects: During navigation, when turning or changing course, adjacent vessels rotate relative to each other. The Y-axis column rotates slightly relative to the Y-axis mounting seat, and is obstructed by the Y-axis opening, becoming stuck in the Y-axis mounting groove. When it is necessary to disconnect adjacent vessels under normal circumstances, the column core is driven to rotate via a drive mechanism. When the width of the column core facing the Y-axis opening is less than the width of the opening, the column core can detach from the Y-axis mounting seat, thus disconnecting the adjacent vessels. Similarly, when forming a fleet, after the Y-axis column core is inserted into the Y-axis mounting seat, the drive mechanism rotates the column core, causing the Y-axis column to lock into the Y-axis mounting seat, thus completing the fleet connection. This design makes the connection and disconnection of fleets easy to operate, and by directly utilizing the connection structure of relative motion between adjacent vessels, the overall connection device has a simple structure.

[0018] Furthermore, a first limiting block is provided on the column core, and a second limiting block is fixed on the column base to limit the rotation angle of the first limiting block.

[0019] Beneficial effects: By rotating the column core relative to the Y-axis mounting seat, the connection or disconnection of the fleet can be achieved. The rotation angle of the column core can be controlled by the setting of the first limit block and the second limit block. Especially when the column core is driven by the manual driving component, the operation difficulty is reduced and the column core can be better controlled so that it can be detached from the Y-axis mounting seat or stuck in the Y-axis mounting seat after rotation.

[0020] Furthermore, the driving component includes a driven gear fixed on the core and a driving gear rotatably connected to the base, with the driving gear and driven gear meshing and driving; the base is equipped with a stop bolt for engaging between adjacent teeth of the driving gear.

[0021] Beneficial effects: The column core is driven to rotate by gear transmission. In order to prevent the driving gear or driven gear from deflecting on its own during navigation, a stop bolt is set to lock the driving gear, so that the column core cannot be driven to rotate relative to the column base without manual intervention.

[0022] Furthermore, a connecting groove is provided on the side wall of the Z-axis column facing away from the Z-axis notch. The opening of the connecting groove is along the radial direction of the Z-axis column. A connecting plate is inserted into the connecting groove. The Z-axis column and the connecting plate are connected by connecting bolts. The axis of the connecting bolts is perpendicular to the direction of the opening of the connecting groove. A reinforcing rib is fixed to one end of the connecting plate that extends out of the Z-axis column.

[0023] Beneficial effects: When the connecting plate is connected to the X-axis or Y-axis rotating assembly, the reinforcing ribs increase the connection strength. The connecting plate also facilitates the rotation of the Z-axis column relative to the Z-axis mounting base, preventing rotational interference when the Z-axis column is directly connected to the X-axis or Y-axis rotating assembly. The connecting bolts further enhance the connection strength between the connecting plate and the Z-axis column, while also increasing the resistance to thrust or tension at the connection point.

[0024] Furthermore, both ends of the X-axis column extend out to the X-axis mounting base. One end of the X-axis column is connected to the Z-axis rotation assembly, and this end is provided with a limiting part for limiting the axial displacement of the X-axis column toward the X-axis mounting base. The other end of the X-axis column is detachably connected to a limiting member for limiting the axial displacement of the X-axis column toward the X-axis mounting base.

[0025] Beneficial effects: Since the rotation axis of the X-axis column is along the direction of the ship's travel, the X-axis column bears the thrust or tension along its axis during the convoy's navigation. Through the setting of the limiting part and the limiting element, the two ends of the X-axis column can be locked with the X-axis mounting seat, so as to better bear the thrust or tension and prevent the X-axis column from detaching from the X-axis mounting seat.

[0026] Furthermore, the limiting component includes a limiting nut threaded onto the X-axis column, and the side wall of the limiting nut is threaded with a limiting bolt for abutting against the X-axis column.

[0027] Beneficial effects: When the X-axis column is subjected to the tension of the stern ship, the limit nut is pulled and stuck on the X-axis mounting seat. The limit nut bears the tension along its axial direction and is easily damaged. Therefore, in this solution, the limit bolts set radially along the limit nut distribute the force and better bear the tension. In addition, the setting of the limit bolts also reduces the possibility of the limit nut rotating and loosening on its own to a certain extent.

[0028] According to embodiments of the present invention, the present invention also employs the following technical solutions:

[0029] The vessel includes a bow and a stern. The stern has a groove, and the bow has a fitting part for inserting into the groove. The opening width of the groove is greater than the width of the fitting part. The bows and sterns of adjacent vessels are connected by a slotted column type vessel jacking connection device. A positioning groove for installing the slotted column type vessel jacking connection device is provided in the middle of the groove.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. The positioning of the groove and the mating part makes it easier to connect and position the ships. On the other hand, the bow of the aft ship is in the wake of the stern of the foreship, which can reduce the navigation resistance of the fleet by utilizing the wake, while improving propulsion efficiency and effectively reducing energy consumption. This is more conducive to the energy-saving, efficient, safe and economical operation of the 10,000-ton fleet.

[0032] 2. The positioning groove makes it easier to install and position the slot-type ship jacking connection device.

[0033] Furthermore, flexible limiting posts are fixed on both sides of the groove to limit the relative swing range of the bow and stern of adjacent vessels.

[0034] Beneficial effects: When adjacent vessels turn and change lanes, and the relative motion is large, the side wall of the mating part of the aft vessel is prone to colliding with the inner wall of the groove. The flexible limiting post reduces collision damage. At the same time, the flexible limiting post also limits the rotation range of adjacent vessels when changing lanes relative to each other, preventing the Y-axis post from detaching from the Y-axis mounting base during turning.

[0051] The present invention will be further described in detail below with reference to the accompanying drawings, and specific embodiments are given.

[0052] Example 1

[0053] like Figure 1 , Figure 2 As shown, the slotted column type ship jacking connection device includes an X-axis rotating assembly, a Y-axis rotating assembly, and a Z-axis rotating assembly. In this embodiment, taking the connection of two ships as an example, the X-axis rotating assembly is installed on barge 1 (i.e., the forward ship), and the Y-axis rotating assembly is installed on jacking boat 2 (i.e., the aft ship) as an example for description. Figure 1 Taking the direction shown as an example, the fleet is sailing from left to right.

[0054] Combination Figure 3 , Figure 4 As shown, the X-axis rotating assembly includes an X-axis mounting base 3 and an X-axis column 4 rotatably connected to the X-axis mounting base 3. The rotation axis of the X-axis column 4 is along the ship's direction of travel (i.e., the ship's length direction). During installation, the X-axis mounting base 3 is fixed to the stern of the barge 1 using conventional connection methods (detachable connection or direct welding). In the actual design process, the X-axis mounting base 3 has an installation space, and the X-axis column 4 only contacts both ends of the X-axis mounting base 3 to reduce friction during rotation of the X-axis column 4 relative to the X-axis mounting base 3.

[0055] The Y-axis rotation assembly includes a Y-axis mounting base 16, a Y-axis mounting groove 17 formed on the Y-axis mounting base 16, and a Y-axis column that is clearance-fitted with the Y-axis mounting groove 17. The rotation axis of the Y-axis column is along the vertical direction (i.e., the height direction of the ship). In specific installation, the Y-axis mounting base 16 is fixed to the bow post of the tugboat 2 according to the conventional connection method in the prior art (detachable connection or direct welding).

[0056] Combination Figure 5 , Figure 6 As shown, the Z-axis rotation assembly is used to connect the X-axis rotation assembly and the Y-axis rotation assembly. The Z-axis rotation assembly includes a Z-axis mounting base 8, a Z-axis mounting groove 9 formed on the Z-axis mounting base 8, and a Z-axis column 10 that is clearance-fitted with the Z-axis mounting groove 9. The axis of the Z-axis column 10 is along the width direction of the ship. In this embodiment, the Z-axis mounting base 8 and the X-axis column 4 are fixedly connected, and the Z-axis column 10 and the Y-axis column are fixedly connected. Specifically, to avoid interference from the Y-axis column on the rotation of the Z-axis column 10 relative to the Z-axis mounting base 8, a connecting groove is formed on the Z-axis column 10. The opening of the connecting groove is radially along the Z-axis column 10. A connecting plate 14 is inserted into the connecting groove. The Z-axis column 10 and the connecting plate 14 are connected by connecting bolts 12. The axis of the connecting bolts 12 is perpendicular to the direction of the opening of the connecting groove. After the Z-axis column 10 and the connecting plate 14 are bolted together, the opening of the connecting groove and the connecting plate 14 are welded together to improve the connection strength between the Z-axis column 10 and the connecting plate 14. In actual design, multiple connecting bolts 12 can be set along the axial direction of the Z-axis column 10, or they can be replaced by pins. A reinforcing rib plate 15 is fixed to one end of the connecting plate 14 that extends out of the Z-axis column 10. Both the connecting plate 14 and the reinforcing rib plate 15 are directly welded to the Y-axis column to enhance the connection strength with the Y-axis column.

[0057] by Figure 2 Taking the state shown as an example, the rotation axes of the X-axis column 4, Y-axis column, and Z-axis column 10 are mutually perpendicular, forming a spatial rectangular coordinate system. This allows the X-axis column 4 to rotate relative to the X-axis mounting base 3 (e.g., ...). Figure 4 (as shown in the diagram), the Y-axis column rotates relative to the Y-axis mounting base 16 (e.g., Figure 15 (as shown in the diagram), the Z-axis column 10 rotates relative to the Z-axis mounting base 8 (e.g., Figure 6 (As shown in the figure) to enable multi-directional relative movement between two adjacent ships in space, meeting various navigation conditions in different waters.

[0058] During a voyage, if one vessel in the fleet runs aground and takes on water, it may experience a large-angle trim or even capsize. Connected vessels are also likely to be affected, potentially leading to a maritime accident for the entire fleet. To address this issue, the Z-axis mounting base 8 has a Z-axis opening 13 for the Z-axis column 10 to engage or disengage radially from the mounting base 8. The Z-axis opening 13 communicates with the Z-axis mounting groove 9. The side wall of the Z-axis column 10 has a Z-axis notch 11 along its axial direction. The Z-axis notch 11 and the connecting groove are located on opposite sides of the Z-axis column 10. Specifically, as shown... Figure 5 Taking the example shown, the width of the Z-direction opening 13 is less than the diameter of the Z-direction column 10 (the maximum width of the Z-direction column 10). The Z-direction notch 11 is formed by directly cutting along the axial direction of the Z-direction column 10, and the cutting surface does not pass through the axis of the Z-direction column 10. The vertical distance from the middle of the Z-direction notch 11 to the side wall of the Z-direction column 10 is the minimum width of the Z-direction column 10. The width of the Z-direction opening 13 is greater than the minimum width of the Z-direction column 10 so that the Z-direction column 10 can be separated from the Z-direction opening 13. In the actual design process, the width of the Z-direction notch 11 can be directly equal to the width of the Z-direction opening 13.

[0059] by Figure 5 Taking the indicated direction as an example, during normal navigation, the Z-direction opening 13 faces left, the Z-direction notch 11 faces right, and the Z-direction column 10 rotates slightly within the Z-direction mounting seat 8. Due to the restriction of the Z-direction opening 13, it cannot detach from the Z-direction mounting seat 8. When the ship experiences a large angle of trim, such as... Figure 6 As shown, the bow of barge 1 is tilted downward at a large angle, the Z-axis column 10 rotates at a large angle relative to the Z-axis mounting seat 8, the Z-axis notch 11 rotates to the Z-axis opening 13, the Z-axis opening 13 no longer blocks the Z-axis column 10, the Z-axis column 10 disengages from the Z-axis mounting seat 8, and the connection between the pusher 2 and barge 1 is released. Even if barge 1 capsizes, it will not affect the pusher 2.

[0060] Based on Example 1, preferably, such as Figure 2 As shown, the length of the Y-direction mounting groove 17 is greater than the axial length of the Y-direction column. In actual design, the Y-direction mounting seat 16 can be designed to be longer, and correspondingly, the Y-direction mounting groove 17 is also designed to be longer to meet the installation position requirements of the Y-direction column within the Y-direction mounting seat 16 when adjacent vessels have different heights on the water surface due to different drafts. Additionally, as... Figure 6 As shown, the bow of barge 1 is tilted downward at a large angle. When the Z-axis column 10 rotates at a large angle relative to the Z-axis mounting seat 8, the Y-axis column is subjected to force and will also slide downward significantly within the Y-axis mounting groove 17.

[0061] like Figure 7As shown, the length of the Z-axis mounting groove 9 is greater than the axial length of the Z-axis column 10, so that the Z-axis column 10 can move horizontally within the Z-axis mounting seat 8, further meeting the relative motion requirements between ships. In the actual design process, the Z-axis mounting seat 8 has an opening on its side and is bolted to a baffle 25. The side of the baffle 25 facing the Z-axis mounting groove 9 is fixed with a shock-absorbing pad (rubber pad) of the prior art. When installing the Z-axis column 10, it is inserted into the Z-axis mounting groove 9 from the side opening of the Z-axis mounting seat 8, and then the opening on the side of the Z-axis mounting seat 8 is closed by the baffle 25, which facilitates the assembly of the Z-axis column 10 and the Z-axis mounting seat 8.

[0062] Based on Example 1, preferably, such as Figure 3 As shown, both ends of the X-axis column 4 extend out of the X-axis mounting base 3. One end of the X-axis column 4 is connected to the Z-axis rotation assembly, and this end is provided with a limiting part 7 to restrict the axial displacement of the X-axis column 4 toward the X-axis mounting base 3. The other end of the X-axis column 4 is detachably connected to a limiting member for restricting the axial displacement of the X-axis column 4 toward the X-axis mounting base 3. Specifically, taking... Figure 3 Taking the direction as an example, the left end of the X-axis column 4 is fixedly welded to the Z-axis mounting seat 8, and the right end of the X-axis column 4 is inserted into the X-axis mounting seat 3 and extends out to the right side of the X-axis mounting seat 3. The limiting component includes a limiting nut 5 threadedly connected to the X-axis column 4. The side wall of the limiting nut 5 is threadedly connected with a limiting bolt 6 for abutting against the side wall of the X-axis column 4. By setting the limiting bolt 6, the force of the limiting nut 5 is shared.

[0063] Example 2

[0064] To facilitate the connection or disconnection of the fleet, in this embodiment, such as Figure 2 , Figure 9 , Figure 10 As shown, the Y-axis column includes a column base 19, a column core 18 rotatably connected to the column base 19, and a driving component for driving the column core 18 to rotate. The column base 19 is welded and fixed to the connecting plate 14 and the reinforcing rib plate 15. The driving component includes a driven gear 22 fixed to the column core 18 and a driving gear 21 rotatably connected to the column base 19. The driving gear 21 and the driven gear 22 mesh for transmission. In actual use, considering the installation position and space, one or more connecting gears 32 can mesh between the driving gear 21 and the driven gear 22. The driving gear 21 can be driven by a conventional motor in the prior art, or a handwheel 33 can be installed for manual operation.

[0065] The column base 19 is equipped with a stop bolt 20 for engaging between adjacent teeth of the drive gear 21. Specifically, a nut is fixed on the column base 19, and the stop bolt 20 is threaded onto the nut. By rotating the stop bolt 20, the end of the stop bolt 20 can be engaged between adjacent teeth of the drive gear 21 or disengaged from the drive gear 21.

[0066] The Y-axis mounting base 16 has a Y-axis opening 31 for the core 18 to be engaged or disengaged radially from the Y-axis mounting base 16, and the side wall of the core 18 has a Y-axis notch 30 axially. Specifically, Figure 10 As shown in the example, both sides of the core 18 are provided with Y-direction notches 30. The Y-direction notches 30 are formed by directly cutting along the axial direction of the core 18, and the cutting surface does not pass through the axis of the core 18. The distance between the two cutting surfaces is equal to or less than the width of the Y-direction opening 31. The width of the Y-direction opening 31 is less than the diameter of the core 18 (i.e., the maximum width of the core 18). When the Y-direction notch 30 is directly opposite the Y-direction opening 31, the core 18 is stuck in the Y-direction mounting seat 16 (e.g., Figure 10 (As shown in the diagram), after rotating the column core 18 90 degrees, the Y-direction column and the Y-direction mounting base 16 can be disengaged (as shown in the diagram). Figure 12 (as shown in the diagram) facilitates the assembly of the Y-axis column and Y-axis mounting base 16. During normal navigation and turning, the column core 18 rotates relative to the Y-axis mounting base 16 without exceeding the limiting range of the Y-axis opening 31 (e.g., Figure 15 (The state shown).

[0067] In the actual design process, the Y-direction mounting seat 16 and the Z-direction mounting seat 8 are both made of seamless steel pipes. The Y-direction opening 31 and the Z-direction opening 13 are formed by cutting the side wall of the seamless steel pipes, so that the cross-section of the Y-direction mounting groove 17 and the Z-direction mounting groove 9 along their radial direction is C-shaped.

[0068] The column core 18 is provided with a first limiting block 23. Specifically, the first limiting block 23 and the column core 18 are fixedly connected by conventional methods in the prior art or are directly integrally formed. The column base 19 is fixed with a second limiting block 24 for limiting the rotation angle of the first limiting block 23. Specifically, as shown in the figure... Figure 11 As shown, the first limiting block 23 is semi-circular, and the second limiting block 24 includes two right-angled sides, with the intersection of the two right-angled sides located at the center of the first limiting block 23. The straight side of the first limiting block 23 and the right-angled side of the second limiting block 24 are in contact. The core 18 is secured within the Y-direction mounting base 16. Figure 10 In the state shown, the engagement state of the first limiting block 23 and the second limiting block 24 is as follows: Figure 11 As shown. When the core 18 rotates 90 degrees, as... Figure 12 In the indicated state, the first limiting block 23 also rotates 90 degrees with the core 18. The engagement state of the first limiting block 23 and the second limiting block 24 is as follows: Figure 13 As shown. By setting the first limiting block 23 and the second limiting block 24, the rotation angle range of the control column core 18 can only be 90 degrees. Especially when the column core 18 is driven by the manual operation of the drive component, the operation difficulty is reduced and the column core 18 can be better controlled to detach from the Y-direction mounting seat 16 or be stuck in the Y-direction mounting seat 16 after rotation.

[0069] In the actual assembly process, the X-direction mounting seat 3 is welded and fixed to the stern of barge 1, the Y-direction mounting seat 16 is welded and fixed to the bow post of pushboat 2, the Z-direction post 10 is welded to the post seat 19 via the connecting plate 14, and the Z-direction mounting seat 8 and X-direction post 4 are welded and fixed. Then, the Z-direction post 10 and Z-direction mounting seat 8 are assembled, and the X-direction post 4 and X-direction mounting seat 3 are assembled. When the two boats are not connected, the X-direction rotating component, the Z-direction rotating component, and the Y-direction post are all located at the stern of barge 1, and only the Y-direction mounting seat 16 is located at the bow of pushboat 2. Then, the two boats are brought close to each other, and the post core 18 of the Y-direction post and the Y-direction mounting seat 16 are assembled and connected to complete the connection between the two boats.

[0070] Example 3

[0071] like Figure 8 , Figure 9 As shown, the vessel includes a bow and a stern. The stern has a groove 26, and the bow has a fitting part 28 for inserting into the groove 26. The opening width of the groove 26 is greater than the width of the fitting part 28, so that the bow of the pusher 2 can swing relative to the stern of the barge 1. The bows and sterns of adjacent vessels are connected by a slotted column type vessel jacking connection device as described in Embodiment 1 or Embodiment 2. The groove 26 has a positioning groove 29 in the middle for installing the slotted column type vessel jacking connection device.

[0072] Both sides of the groove 26 are fixed with flexible limiting posts 27 for limiting the relative swing range of the bow and stern of adjacent vessels. The flexible limiting posts 27 are made of rubber posts from the prior art. Figure 14 As shown, during the turning process of the fleet, the two adjacent ships swing relative to each other around the rotation axis of the column core 18. By setting the width of the groove 26 and the width of the positioning groove 29, the maximum range of relative swing between the two ships can be limited. In order to prevent the bow of the pusher 2 from hitting the side wall of the stern groove 26 of the barge 1, a flexible limiting column 27 is set for buffering.
