Description

Technical Field

[0001] This application relates to the field of shipbuilding, and in particular to a spherical top plate structure for a ship's support. Background Technology

[0002] During the assembly of ship sections, due to the large size of the sections, it is necessary to use supports to ensure the stability of the sections. The structure of the supports generally consists of a support base, a lifting threaded rod top plate, and most of the current supports can only play a supporting role and cannot be adjusted over a wide range of angles. Furthermore, the surface of the ship is not always flat, especially the bottom of the ship, which is prone to tilting.

[0003] To facilitate support for tilted parts of the hull, a connecting ball head is usually fixed on the lifting threaded rod. The connecting ball head is rotatably connected to the top plate. When the top plate supports the hull, if the bottom of the hull tilts, the top plate rotates on the connecting ball head to adapt to the tilted surface of the hull. Different top seats are fixed on the top plate to adapt to the shape of different contact points of the hull.

[0004] However, the connection between the top seat and the top plate of the traditional support is usually fixed with bolts. Although this connection method ensures the stability of the connection to a certain extent, when the top seat needs to be replaced, the operator needs to use tools to remove the bolts one by one, which is a tedious and time-consuming process. Utility Model Content

[0005] The purpose of this application is to address the problem that the connection between the top seat and the top plate of a traditional pier, as mentioned in the background art, is usually fixed with bolts. Although this connection method ensures the stability of the connection to a certain extent, when the top seat needs to be replaced, the operator needs to use tools to disassemble the bolts one by one, which is a cumbersome and time-consuming process. This application provides a spherical top plate structure for a marine pier.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution: A spherical top plate structure for a marine support includes a support base, a nut ring fixed on the support base, a lifting threaded rod threadedly connected to the nut ring, a plurality of rotating handles fixed on the lifting threaded rod, a connecting ball head fixed to one end of the lifting threaded rod, a top plate rotatably connected to the connecting ball head, a top seat provided on the top plate, a quick fixing mechanism provided between the top seat and the top plate, and an auxiliary support mechanism provided between the top plate and the lifting threaded rod.

[0007] By adopting the above technical solution, the top mount is connected to the top plate using a quick-fixing mechanism. When disassembling and installing the top mount, the quick-fixing mechanism is used to disassemble and install the top mount, which makes it convenient and quick to replace the top mount on the top plate and facilitates the use of different top mounts to support the ship's support position.

[0008] Furthermore, the quick-fixing mechanism includes two fixing blocks symmetrically fixed on the top seat. The top plate has an installation groove corresponding to the top seat. The inner wall of the installation groove has two symmetrical fixing grooves one and two symmetrical fixing grooves two. The fixing grooves one and two are connected. The side of the fixing groove two away from the connecting ball head is open. A limiting component is provided in the fixing groove two. The top plate has a snap-fit ​​component, which corresponds to the limiting component.

[0009] By adopting the above technical solution, the fixing block on the top seat enters from the fixing groove one into the fixing groove two, and then slides in the fixing groove two and is restricted by the limiting component, thereby facilitating the fixing and disassembly of the top seat and the top plate, and making it convenient to replace different top seats.

[0010] Furthermore, the limiting component includes a limiting rod slidably connected to the top plate. The limiting rod passes through the top plate and one end extends into the fixing groove 2. The end of the limiting rod extending into the fixing groove 2 is provided with an abutting inclined surface, which faces the fixing groove 1.

[0011] By adopting the above technical solution, when the fixed block slides in the second fixed groove, the fixed block pushes against the inclined surface, allowing the fixed block to pass under the limiting rod. Then the limiting rod restricts the fixed block, thereby making it convenient to restrict the fixed block in the second fixed groove.

[0012] Furthermore, a slidable limiting ring is fitted onto the limiting rod, the limiting ring is fixedly connected to the top plate, a limiting block is fixed to the inner wall of the limiting ring, a limiting groove is formed on the limiting rod, the limiting block is located in the limiting groove and is slidably connected to the limiting rod.

[0013] By adopting the above technical solution, when the limiting rod slides, the limiting block on the limiting ring slides in the limiting groove on the limiting rod, thereby reducing the possibility of the limiting rod rotating when sliding.

[0014] Furthermore, a limiting spring is sleeved on the limiting rod, and both ends of the limiting spring are fixedly connected to the limiting rod and the limiting ring.

[0015] By adopting the above technical solution, the limiting rod is supported by the limiting spring, which makes it easy to stably insert the limiting rod into the second fixed groove.

[0016] Furthermore, the locking assembly includes a sliding rail disposed on one side of the limiting rod, the sliding rail being fixedly connected to the top plate, a locking block being slidably connected on the sliding rail, and a locking groove corresponding to the locking block being formed on the limiting rod.

[0017] By adopting the above technical solution, the snap-fit ​​block is inserted into the snap-fit ​​groove on the limiting rod, which can conveniently limit the pulled-up limiting rod, and thus facilitate the removal of the fixing block from the fixing groove two.

[0018] Furthermore, the auxiliary support mechanism includes a connecting seat rotatably connected to the lifting threaded rod, and a plurality of rotating blocks are rotatably connected between the connecting seat and the top plate. A telescopic component is provided between the connecting seat and the rotating blocks of the top plate.

[0019] By adopting the above technical solution, the top plate is supported by the telescopic assembly between the rotating block on the connecting seat and the rotating block on the top plate. This allows the top plate to be supported by sliding rod one and sliding rod two, further improving the stability of the top plate. Furthermore, the telescopic assembly includes a sliding rod 1 disposed between the connecting seat and the top plate. The sliding rod 1 is fixedly connected to the rotating block on the connecting seat. A sliding rod 2 is slidably connected to the sliding rod 1. The end of the sliding rod 2 away from the sliding rod 1 is fixedly connected to the rotating block on the top plate. A fixing bolt is threadedly connected to the end of the sliding rod 2 near the sliding rod 1. The fixing bolt passes through the sliding rod 2 and abuts against the sliding rod 1.

[0020] By adopting the above technical solution, after the top plate is adjusted, the fixing bolt is rotated so that it contacts the sliding rod one, thereby making it easy to fix the sliding rod one and the sliding rod two, and using the sliding rod one and the sliding rod two to provide auxiliary support for the top plate.

[0021] In summary, this application includes at least one of the following beneficial effects; 1. In this application, when the top seat on the top plate needs to be replaced, the limiting rod is pulled, allowing it to slide on the limiting ring. After the locking groove on the limiting rod aligns with the locking block on the sliding rail, the locking block slides on the sliding rail, inserting into the locking groove to limit the limiting rod and disengage it from the second fixing groove. Then, the top seat is rotated, causing the top seat to drive the fixing block to slide in the second fixing groove. After the fixing block moves to the position where the first fixing groove and the second fixing groove are connected, the top seat drives the fixing block to move away from the top plate, disengaging the top seat and the fixing block from the top plate. Then, the locking block... The limit rod is reset under the push of the limit spring. Then, the new top seat is taken out, and the fixing block on the top seat is aligned with the fixing groove one on the top plate. The fixing block moves from the fixing groove one into the fixing groove two. Then, the top seat is rotated, causing the top seat to move the fixing block in the fixing groove two. The fixing block abuts against the abutting inclined surface on the limit rod. Under the push of the fixing block, the limit rod rises from the fixing groove two. Then, the fixing block passes through the limit rod, and the limit rod is reset under the push of the limit spring. The replacement of the new top seat is completed, which achieves the purpose of convenient fixing and disassembly of the top seat and the top plate, and convenient replacement of different top seats.

[0022] 2. In this application, when the top plate rotates and tilts on the connecting ball head, the top plate drives the rotating block, which in turn drives the sliding rod two, allowing the sliding rod two to slide on the sliding rod one. The rotating block on the connecting seat supports the sliding rod one, and the sliding rod one supports the sliding rod two. After the top plate is adjusted, the fixing bolt is rotated, causing it to move on the sliding rod two and contact the sliding rod one, thus fixing the sliding rod one and the sliding rod two. By using the sliding rod one and the sliding rod two to provide auxiliary support for the top plate, the stability of the top plate is further improved. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1 —5 provides further details regarding this application.

[0026] This application discloses a spherical top plate structure for a marine support pier.

[0027] Reference Figure 1 , Figure 2 and Figure 3 A spherical top plate structure for a marine support includes a support base 1, a nut ring 2 fixed on the support base 1, a lifting threaded rod 3 threadedly connected to the nut ring 2, several rotating handles 4 fixed on the lifting threaded rod 3, a connecting ball head 5 fixed to one end of the lifting threaded rod 3, a top plate 6 rotatably connected to the connecting ball head 5, a top seat 9 provided on the top plate 6, a quick fixing mechanism 7 provided between the top seat 9 and the top plate 6, and an auxiliary support mechanism 8 provided between the top plate 6 and the lifting threaded rod 3.

[0028] When using this marine support, different top mounts 9 are selected according to the location where the ship needs support. The top mount 9 is then fixed to the top plate 6 using the quick-fixing mechanism 7. Then, the lifting threaded rod 3 is driven by rotating the handle 4, allowing it to move on the nut ring 2. The lifting threaded rod 3 drives the connecting ball head 5, which in turn drives the top plate 6. The top plate 6 then causes the top mount 9 to contact the ship's support location. When the top plate 6 is in contact with the ship's support location, it is adjusted according to the offset angle of the support location, supported by the connecting ball head 5, so that the top mount 9 on the top plate 6 is fully in contact with the ship's support location. Then, the auxiliary support mechanism 8 is used to support and limit the top plate 6. By connecting the top mount 9 to the top plate 6 using the quick-fixing mechanism 7, the top mount 9 can be easily and quickly replaced on the top plate 6, allowing for the use of different top mounts 9 to contact the ship's support location.

[0029] Reference Figure 2 , Figure 3 and Figure 5The quick-fixing mechanism 7 includes two fixing blocks 71 symmetrically fixed on the top seat 9. The top plate 6 has an installation groove corresponding to the top seat 9. The inner wall of the installation groove has two symmetrical fixing grooves 72 and two symmetrical fixing grooves 73. Fixing grooves 72 and 73 are connected. The side of fixing groove 73 away from the connecting ball head 5 is open. A limiting component 74 is provided in fixing groove 73. The top plate 6 is provided with a snap-fit ​​component 75, which corresponds to the limiting component 74.

[0030] In addition, the limiting component 74 includes a limiting rod 741 that is slidably connected to the top plate 6. The limiting rod 741 passes through the top plate 6 and one end extends into the second fixing groove 73. The end of the limiting rod 741 that extends into the second fixing groove 73 is provided with an abutting slope 742, which faces the first fixing groove 72.

[0031] Furthermore, a sliding connection limit ring 745 is fitted on the limit rod 741, the limit ring 745 is fixedly connected to the top plate 6, a limit block 746 is fixedly fixed on the inner wall of the limit ring 745, a limit groove 744 is opened on the limit rod 741, the limit block 746 is located in the limit groove 744 and is slidably connected to the limit rod 741.

[0032] Furthermore, a limiting spring 743 is fitted on the limiting rod 741, and both ends of the limiting spring 743 are fixedly connected to the limiting rod 741 and the limiting ring 745.

[0033] Furthermore, the snap-fit ​​assembly 75 includes a sliding rail 753 disposed on one side of the limiting rod 741. The sliding rail 753 is fixedly connected to the top plate 6. A snap-fit ​​block 751 is slidably connected on the sliding rail 753. A snap-fit ​​groove 752 corresponding to the snap-fit ​​block 751 is provided on the limiting rod 741.

[0034] When it is necessary to replace the top seat 9 on the top plate 6, first pull the limiting rod 741, allowing it to slide on the limiting ring 745. After the locking groove 752 on the limiting rod 741 aligns with the locking block 751 on the sliding rail 753, let the locking block 751 slide on the sliding rail 753, allowing it to insert into the locking groove 752, thus limiting the limiting rod 741 and disengaging it from the second fixing groove 73. Then, rotate the top seat 9, causing it to drive the fixing block 71 to slide in the second fixing groove 73. After the fixing block 71 moves to the position where the first fixing groove 72 and the second fixing groove 73 connect, let the top seat 9 drive the fixing block 71 to move away from the top plate 6, disengaging it from the top plate 6. Then, let the locking block 751 reset, and the limiting rod 741 reset under the push of the limiting spring 743. Take out the new top seat 9, align the fixing block 71 on the top seat 9 with the fixing groove 72 on the top plate 6, and let the fixing block 71 move from the fixing groove 72 into the fixing groove 73. Then rotate the top seat 9, so that the top seat 9 drives the fixing block 71 to slide in the fixing groove 73. The fixing block 71 abuts against the abutting inclined surface 742 on the limiting rod 741. Under the push of the fixing block 71, the limiting rod 741 rises from the fixing groove 73. Then the fixing block 71 passes through the limiting rod 741. Then the limiting rod 741 is reset under the push of the limiting spring 743, completing the replacement of the new top seat 9. By fixing the fixing block 71 on the top seat 9, the fixing block 71 can move in the fixing groove 72 and the fixing groove 73 on the top plate 6, and then the limiting rod 741 is used for limiting, so that the fixing and disassembly of the top seat 9 and the top plate 6 can be conveniently fixed, and different top seats 9 can be easily replaced.

[0035] Reference Figure 1 and Figure 4 The auxiliary support mechanism 8 includes a connecting seat 81 rotatably connected to the lifting threaded rod 3. Several rotating blocks 82 are rotatably connected between the connecting seat 81 and the top plate 6. A telescopic component 83 is provided between the connecting seat 81 and the rotating blocks 82 of the top plate 6.

[0036] In addition, the telescopic assembly 83 includes a sliding rod 831 disposed between the connecting seat 81 and the top plate 6. The sliding rod 831 is fixedly connected to the rotating block 82 on the connecting seat 81. A sliding rod 832 is slidably connected to the sliding rod 831. The end of the sliding rod 832 away from the sliding rod 831 is fixedly connected to the rotating block 82 on the top plate 6. A fixing bolt 833 is threadedly connected to the end of the sliding rod 832 near the sliding rod 831. The fixing bolt 833 passes through the sliding rod 832 and abuts against the sliding rod 831.

[0037] When the top plate 6 is rotated and tilted on the connecting ball joint 5, the top plate 6 drives the rotating block 82, which in turn drives the sliding rod 832, causing the sliding rod 832 to slide on the sliding rod 831. The rotating block 82 on the connecting seat 81 supports the sliding rod 831, and the sliding rod 831 supports the sliding rod 832. After the top plate 6 is adjusted, the fixing bolt 833 is rotated, causing the fixing bolt 833 to move on the sliding rod 832, so that the fixing bolt 833 abuts against the sliding rod 832. The movable rod 831 fixes the sliding rod 831 and the sliding rod 832, and uses the sliding rod 831 and the sliding rod 832 to provide auxiliary support for the top plate 6. When the top plate 6 is adjusted, the top plate 6 drives the sliding rod 832 to move on the sliding rod 831. After the adjustment is completed, the sliding rod 831 and the sliding rod 832 are fixed, so that the top plate 6 can be supported by the sliding rod 831 and the sliding rod 832, thereby further improving the stability of the top plate 6.

[0038] Working principle: When using this marine support, select a different top seat 9 according to the location and shape of the ship that needs support. Then, take out the new top seat 9 and align the fixing block 71 on the top seat 9 with the fixing groove 72 on the top plate 6. Let the fixing block 71 move from the fixing groove 72 into the fixing groove 73. Then, rotate the top seat 9, causing the top seat 9 to move the fixing block 71 in the fixing groove 73. The fixing block 71 abuts against the abutting inclined surface 742 on the limiting rod 741. Under the push of the fixing block 71, the limiting rod 741 rises from the fixing groove 73. Then, the fixing block 71 passes through the limiting rod 741. Then, the limiting rod 741 is reset under the push of the limiting spring 743, completing the replacement of the new top seat 9. Then, use the rotating handle 4... The lifting threaded rod 3 is moved on the nut ring 2, which in turn drives the connecting ball head 5. The connecting ball head 5 drives the top plate 6, which in turn drives the top seat 9 to abut against the support position of the ship. When the top plate 6 abuts against the support position of the ship, it is adjusted according to the offset angle of the support position, supported by the connecting ball head 5, so that the top seat 9 on the top plate 6 is fully abutted against the support position of the ship. Finally, the fixing bolt 833 is rotated, which moves on the sliding rod 2 832, so that the fixing bolt 833 abuts against the sliding rod 1 831, fixing the sliding rod 1 831 and the sliding rod 2 832. The sliding rod 1 831 and the sliding rod 2 832 are used to provide auxiliary support for the top plate 6.
