Description

Technical Field

[0001] This invention belongs to the field of marine engineering technology, and in particular relates to an ultra-large deep-water jacket support structure for shipboard propulsion and its dismantling method. Background Technology

[0002] As water depth increases, the weight of the jacket foundation, which forms the basis of the offshore platform, increases exponentially, posing significant challenges to the loading and transportation of the jacket platform. To prevent large deformations during construction of the ultra-large jacket, short fixed slippers need to be added to the bottom of the launching truss to ensure the jacket legs remain straight. Since there is a distance between the continuous slipper and the fixed slipper, booster jacks can be added between them to enhance the loading and transportation capabilities of the jacket platform.

[0003] The traditional method of adding booster jacks is not applicable to the installation of ultra-large deep-water jacket structures on ships. This is because after the jacket slides, all interference on the slideway needs to be removed immediately to prevent the fixed slip shoe from colliding with the jack reinforcement structure. Therefore, the traditional method of adding booster jacks to remove small jacket structures is not suitable for the installation of ultra-large deep-water jacket structures on ships.

[0004] Therefore, there is an urgent need to design a jacket support structure for shipboard mounting to solve the problems mentioned above. Summary of the Invention

[0005] To address the technical problem mentioned in the background art that the traditional method of adding booster jacks cannot immediately remove all interference on the slideway after the jacket slides, a jacket loading booster support structure is provided to solve the problems of jacket sliding and immediate removal of the booster support structure after sliding.

[0006] To achieve the above objectives, the specific technical solution of the jacket support structure for ship mounting of the present invention is as follows: A jacket support structure for ship loading includes a pad, a first ear plate, and a second ear plate. The first ear plate and the second ear plate are connected to the pad at intervals. The first ear plate and the second ear plate have symmetrical through holes. A fixing pin is inserted into the through holes to connect the first ear plate and the second ear plate to a slide rail. A jack base is provided on the pad. A booster jack is placed between the jack base and the continuous sliding shoe of the jacket. The booster jack is activated to push the continuous sliding shoe so that the jacket slides along the slide rail.

[0007] Furthermore, the first ear plate and the second ear plate are vertically connected to the pad plate, so that the first ear plate, the pad plate and the second ear plate are arranged in a U-shape on the slide.

[0008] Furthermore, a mounting plate is connected to the through hole of the first ear plate and the second ear plate, and a fixing pin is inserted along the mounting plate to fix the first ear plate and the second ear plate to both sides of the slide.

[0009] Furthermore, a T-shaped beam is provided on the pad, with one side of the T-shaped beam abutting against the jack base, and the booster jack abutting against the T-shaped beam along the length of the T-shaped beam.

[0010] Furthermore, triangular plates are connected between the pad and the first ear plate and the second ear plate respectively, so that the first ear plate and the second ear plate are fixedly connected to the pad respectively.

[0011] Furthermore, a handle plate is connected between the triangles, and the side of the handle plate away from the triangles is connected to the pad.

[0012] A method for dismantling a jacket support structure for shipboard propulsion mainly includes the following steps: S1. The first ear plate and the second ear plate are fixedly connected to the slide rail by a fixed pin, so that the pad is located between the continuous slide shoe and the fixed slide shoe; S2. Place the booster jack on the T-beam; S3. Activate the booster jacks to make the jacket structure begin to move slowly forward; S4. After the guide frame slides, immediately cut the first or second ear plate and remove the booster jack. S5. Remove the fixing pin and remove the pad from the slide.

[0013] Furthermore, cutting lines are marked along the length of the first and second ear plates, and the first or second ear plate is cut along the cutting lines.

[0014] The jacket support structure for shipboard mounting of the present invention has the following advantages: The ship-loading booster support structure can be quickly dismantled without interrupting the jacket installation process, significantly increasing the jacket's boosting capacity. The booster support structure is installed at the end of the continuous slipper of the launching truss, allowing for rapid dismantling and safe transfer with minimal welding and cutting work after the jacket slides. This application avoids obstructing the continuous slipper, does not affect the jacket installation time, and offers convenient overall operation and construction, reducing construction risks and project costs.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of the invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0019] The following is a reference to the appendix. Figure 1 To be continued Figure 3 The present invention describes the jacket support structure for ship mounting.

[0020] like Figure 1 and Figure 3 As shown, the jacket support structure for ship loading in this invention includes a pad 1, a first ear plate 2, and a second ear plate 3. The first ear plate 2 and the second ear plate 3 are connected to the pad 1 at intervals. The first ear plate 2 and the second ear plate 3 are symmetrically provided with through holes 10. A fixing pin 4 is inserted into the through hole 10 so that the first ear plate 2 and the second ear plate 3 are connected to the slide rail 5. A jack base 6 is provided on the pad 1. A booster jack 9 is placed between the jack base 6 and the continuous sliding shoe 8 of the jacket 7. The booster jack 9 is activated to push the continuous sliding shoe 8 so that the jacket 7 slides along the slide rail 5.

[0021] Without stopping the loading of the jacket 7 onto the ship, the loading booster support structure can be quickly dismantled, significantly increasing the booster capacity of the jacket 7. The loading booster support structure is installed at the end of the continuous slipper 8 of the launching truss. After the jacket 7 slides, it can be quickly dismantled and safely transferred with minimal welding and cutting work.

[0022] Furthermore, such as Figure 3As shown, the first ear plate 2 and the second ear plate 3 are vertically connected to the pad 1 so that the first ear plate 2, the pad 1 and the second ear plate 3 are arranged in a U-shape on the slide rail 5; the through holes 10 of the first ear plate 2 and the second ear plate 3 are connected to the mounting plate 11, and the fixing pin 4 is inserted along the mounting plate 11 so that the first ear plate 2 and the second ear plate 3 are fixedly connected to both sides of the slide rail 5.

[0023] In this embodiment, preferably, the first ear plate 2 and the second ear plate 3 are both vertically welded to the bottom of the pad plate 1. The distance between the first ear plate 2 and the second ear plate 3 is determined by the width of the slide 5, so that the first ear plate 2, the pad plate 1 and the second ear plate 3 are slidably arranged in a U-shape on the slide 5; wherein the slide 5 is a concrete slide.

[0024] Multiple through holes 10 are provided on the first ear plate 2 and the second ear plate 3 respectively. In use, through holes corresponding to the through holes are opened on the slide rail 5, and the fixing pin 4 is inserted into the through hole of the slide rail through the through hole 10, so that the first ear plate 2 and the second ear plate 3 are fixedly set on both sides of the slide rail 5.

[0025] A mounting plate 11 is connected at the through hole 10, so that the end of the fixing pin 4 abuts against the mounting plate 11, thereby fixing the first ear plate 2 and the second ear plate 3.

[0026] Furthermore, such as Figure 2 and Figure 3 As shown, a T-beam 12 is provided on the pad 1. One side of the T-beam 12 abuts against the jack base 6, and the booster jack 9 abuts against the T-beam 12 along the length of the T-beam 12. Triangular plates 13 are respectively connected between the pad 1 and the first ear plate 2 and the second ear plate 3, so that the first ear plate 2 and the second ear plate 3 are respectively fixedly connected to the pad 1. A handle plate 14 is connected between the triangular plates 13, and the side of the handle plate 14 away from the triangular plates 13 is connected to the pad 1.

[0027] In this embodiment, preferably, a T-beam 12 is fixedly connected along the length direction of the pad 1 (i.e., the length direction of the slide 5). One end of the T-beam 12 is tightly abutted against the jack base 6. The jack base 6 is welded to the pad 1. A booster jack 9 is set along the length direction of the T-beam 12, so that one end of the booster jack 9 abuts against the T-beam 12. The output end of the booster jack 9 pushes the continuous slide shoe 8.

[0028] Triangular plates 13 are connected between the pad 1 and the first ear plate 2 and the second ear plate 3, respectively, so that the first ear plate 2 and the second ear plate 3 are fixedly connected to the pad 1. Preferably, a cutting line 15 is marked along the length direction of the first ear plate 2 and the second ear plate 3. The triangular plates 13 are connected above the cutting line 15 of the first ear plate 2 and the second ear plate 3, and the first ear plate 2 or the second ear plate 3 is cut along the cutting line 15, thereby realizing the rapid separation of the ship loading booster support structure from the slide 5. A knife handle plate 14 is connected between the triangular plates 13. The side of the knife handle plate 14 away from the triangular plates 13 is connected to the pad 1, thereby further fixing the pad 1 to the first ear plate 2 and the second ear plate 3.

[0029] As a preferred embodiment, as the weight of the jacket 7 gradually increases, a single assembly booster support structure cannot overcome the static friction between the jacket 7 and the slideway 5. At this time, multiple continuous slippers 8 and support slippers are arranged sequentially and at intervals along the length of the jacket 7, so that multiple assembly booster support structures are arranged between the continuous slippers 8 and the support slippers. That is, multiple booster jacks 9 simultaneously apply booster force to multiple continuous slippers, thereby enhancing the booster capability of the jacket 7.

[0030] This application also provides a method for dismantling a jacket support structure for shipboard propulsion, which mainly includes the following steps: S1. The first ear plate 2 and the second ear plate 3 are fixedly connected to the slide rail 5 by the fixed pin 4, so that the pad plate 1 is located between the continuous slide shoe 8 and the fixed slide shoe. S2. Place the booster jack 9 on the T-beam 12; Among them, the bottom of the launching truss may have multiple continuous slippers 8 and fixed slippers, and multiple booster jacks 9 are set between pairs of slippers to increase the ship loading capacity of the jacket 7. S3. Start the booster jack 9 to make the jacket 7 begin to move slowly forward; After all the preparatory work for loading the ship is completed, select a suitable tide and start the loading jacks and booster jacks 9. At this time, the jacket 7 begins to move slowly forward. S4. After the guide frame 7 slides, immediately cut the first ear plate 2 or the second ear plate 3, and remove the booster jack 9. The principle of complete dismantling should be based on minimizing the amount of welding and cutting work. Cutting should be carried out at the cutting line 15 of the first ear plate 2 or the second ear plate 3 to ensure the integrity of the pad plate 1 as much as possible. S5. Remove the fixing pin 4 and remove the pad 1 from the slide rail 5; During the dismantling process, the loading of the jacket frame 7 into the ship does not stop. Priority is given to dismantling the pad plate 1, jack base 6, and T-beam 12, which are located on the upper part of the slide 5. If the distance between the continuous slide shoe 8 and the fixed slide shoe is short or there is a time limit for dragging, the dismantling of the fixed pin 4, ear plate, and plate 11 can be carried out at the fixed slide shoe through the reinforcement structure after the dismantling work.

[0031] Based on the jacket support structure for ship loading, this invention avoids obstructing the continuous slipper 8 and will not affect the loading time of the jacket 7. The overall operation is convenient and easy to construct, reducing construction risks and project costs.

[0032] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
