Description

Technical Field

[0001] This invention relates to the field of positioning fixture technology, and in particular to a splicing positioning fixture for offshore pile legs. Background Technology

[0002] Based on the current needs for offshore wind power installation and maintenance, there is a need for self-elevating and self-propelled offshore wind power installation and maintenance platforms, especially in deep-sea areas. However, this type of vessel has very high technical and quality requirements for the legs, pile frames, and pile shoes. Currently, most of the legs are over 100 meters high. Due to the lifting capacity of local shipyards and the limitations of the ship's passage height through bridges, the legs need to be floated at the dock and spliced ​​using a ship crane.

[0003] However, it is worth considering that when welding and assembling two adjacent pile legs, the swaying of the water surface can affect the splicing accuracy and quality of the pile legs, making it inconvenient for actual operation.

[0004] Therefore, in order to solve the above problems, a more suitable facility that meets the needs of users is needed. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide a splicing and positioning fixture for offshore pile legs, so as to solve the problem that the splicing accuracy and quality of pile legs are affected by the swaying of the water surface.

[0006] To achieve the above objectives, the present invention provides a splicing and positioning fixture for offshore pile legs, comprising two first arc-shaped plates and two second arc-shaped plates. The two first arc-shaped plates and the two second arc-shaped plates are fixedly connected to each other by mounting components. A first support seat is fixedly connected to the outer wall of each of the two first arc-shaped plates, and a second support seat is threadedly connected to the outer wall of each of the two second arc-shaped plates. A guide groove is provided on the side of the first support seat and the second support seat that are close to each other. A first guide strip is slidably disposed in the guide groove on the first support seat, and a second guide strip is slidably disposed in the guide groove on the second support seat. The second guide bar is equipped with a plug-in fixing structure that is compatible with the first guide bar. The second support base is equipped with a stop limiting component that limits the position of the second guide bar and the second arc plate respectively. Limiting grooves are opened on the inner walls of the first arc plate and the second arc plate, and limiting plates for fixed connection with the pile leg are provided in the limiting grooves.

[0007] Optionally, the plug-in fixing structure includes at least one limiting sleeve fixedly installed on the second guide strip, and the first guide strip has at least one plug rod on the side facing the second guide strip, and the number of plug rods and limiting sleeves is the same. The limiting sleeve is equipped with a fixing unit that cooperates with the plug rod, and the first guide strip is equipped with a synchronous sliding structure for driving the plug rod to move vertically.

[0008] Optionally, the synchronous sliding structure includes a fixed sleeve sleeved on the outside of the insertion rod, the fixed sleeve being fixedly connected to the first guide strip, the first guide strip having a first movable frame on the side facing the second guide strip, the fixed sleeve passing through the first movable frame, and at least one rectangular hole being opened on the inner wall of the fixed sleeve, a connecting block being provided in the rectangular hole, the connecting block being fixedly connected to the insertion rod, and the connecting block being fixedly connected to the first movable frame.

[0009] Optionally, one of the first movable frames has a first plug fixedly connected to both ends, and the other first movable frame has a first slot opened at both ends, with the first plug located in the corresponding first slot.

[0010] Optionally, the fixing unit includes at least one first support portion fixedly installed on the limiting sleeve, a locking post passing through the first support portion, an elastic element for applying tension to the locking post installed on the first support portion, a positioning plate passing through the limiting sleeve, a positioning hole opened on the insertion rod, the bottom end of the insertion rod being located in the corresponding limiting sleeve, and the positioning plate passing through the corresponding positioning hole, and the end of the locking post passing through the positioning plate.

[0011] Optionally, the elastic element includes a fixed plate fixedly installed at the end of the locking post away from the positioning plate, and a tension spring is sleeved on the outside of the locking post, with the two ends of the tension spring fixedly connected to the first support part and the fixed plate, respectively.

[0012] Optionally, the mounting component includes mounting plates that are fixedly mounted on both ends of one of the first arc-shaped plates and one of the second arc-shaped plates, respectively. The other first arc-shaped plate and the other second arc-shaped plate are respectively provided with mounting grooves at both ends. The mounting plates are located in the corresponding mounting grooves, and the mounting plates are connected to the corresponding first arc-shaped plate or second arc-shaped plate by bolts.

[0013] Optionally, the first guide bar and the second guide bar are respectively rotatably connected to the side of the guide bar that is close to each other, and the ball is in contact with the inner wall of the guide groove.

[0014] Optionally, the stop and limit assembly includes a support block fixedly installed on the side of the second support base away from the second arc-shaped plate, a second movable frame slidably sleeved on the outside of the support block, a support plate fixedly installed on the second guide strip, a first stop groove opened on the support plate, a first stop block adapted to the first stop groove fixedly installed on the second movable frame, a fixed seat provided on the side of the second arc-shaped plate away from the first arc-shaped plate, a plurality of connecting columns fixedly installed on the fixed seat, and the connecting columns are fixedly connected to the second arc-shaped plate, a plurality of second stop grooves opened on the fixed seat, a second stop block adapted to the second stop groove fixedly installed on the second movable frame, and a position locking unit adapted to the support block installed on the second movable frame.

[0015] Optionally, the position locking unit includes a second support portion fixedly installed on the second movable frame, a second insert block passing through the second support portion, two second slots being opened on the support block, the end of the second insert block being located in one of the second slots, a fixing frame being fixedly installed on the second movable frame, the second insert block and the fixing frame being connected by a compression spring, and a handle being fixedly installed on the second insert block.

[0016] When the first stop block is located in the first stop groove and the second stop block is not located in a corresponding second stop groove, the first stop block limits the position of the first stop groove and the support plate, thereby fixing the second guide bar relative to the second movable frame and the second support base, preventing the second guide bar from sliding in the guide groove. Since the second stop block is not located in a corresponding second stop groove, the second support base and the second movable frame can rotate relative to the second arc plate. When it is necessary for the second support base to be fixed relative to the second arc plate and the second guide bar to slide relative to the guide groove, the operator drives the second insert block to move by means of the handle. The compression spring is in a compressed state, causing the end of the second insert block to disengage from a corresponding second slot. The operator then drives the second movable frame relative to the support block and the second support plate. The support moves horizontally so that the second stop block is inserted into a corresponding second stop groove, and the first stop block slides out of the first stop groove, so that the second support and the second movable frame are fixed relative to the fixed seat and the second arc plate, and the support plate and the second guide bar can rotate relative to the second support. At this time, the end of the second insert moves to one side of the other second slot. The operator releases the handle, and the compressed spring drives the second insert to move so that the end of the second insert is inserted into the corresponding second slot, so that the second movable frame is fixed relative to the support block and the second support. When the second guide bar and the first guide bar slide in the corresponding guide grooves, the ball rolls on the inner wall of the guide groove. Through the design of the ball, the resistance encountered by the second guide bar and the first guide bar when sliding is reduced.

[0017] The beneficial effects of this invention are as follows: By driving the second support base and the second guide strip to rotate synchronously, the second support base moves relative to the second arc-shaped plate. The second support base, through the first support base and the first arc-shaped plate, drives the ends of the two pile legs to be tightly pressed together. Then, the position of the second arc-shaped plate is limited by the stop and limit component, fixing the second arc-shaped plate relative to the second support base and preventing the second support base from rotating and wobbling relative to the second arc-shaped plate due to non-human factors. Furthermore, the stop and limit component no longer limits the position of the second guide strip, allowing it to slide within the guide groove. During the welding process, the two pile legs... Without any shaking, workers can weld at the connection between the two pile legs using welding equipment. When the plug-in fixing structure obscures part of the connection between the two pile legs, the second guide strip can slide in the guide groove. Workers can drive the second guide strip to slide in the guide groove, and the second guide strip drives the first guide strip to slide in the guide groove located on the first support seat through the plug-in fixing structure. This changes the position of the plug-in fixing structure, ensuring that welding can be performed at different positions on the connection between the two pile legs. During the welding process, there will be no shaking between the two pile legs, improving the accuracy and quality of the pile leg splicing. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0022] This embodiment proposes a splicing and positioning fixture for offshore pile legs, such as... Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, it includes two first arc-shaped plates 1 and two second arc-shaped plates 2. The two first arc-shaped plates 1 and the two second arc-shaped plates 2 are fixedly connected to each other by mounting parts. A first support seat 3 is fixedly connected to the outer wall of each of the two first arc-shaped plates 1, and a second support seat 4 is threadedly connected to the outer wall of each of the two second arc-shaped plates 2. A guide groove 5 is provided on the side of the first support seat 3 and the second support seat 4 that are close to each other. A first guide strip 6 is slidably provided in the guide groove 5 on the first support seat 3, and a second guide strip 8 is slidably provided in the guide groove 5 on the second support seat 4. The second guide bar 8 is equipped with a plug-in fixing structure adapted to the first guide bar 6. The second support base 4 is equipped with a stop limiting component that limits the position of the second guide bar 8 and the second arc plate 2 respectively. Limiting grooves 16 are opened on the inner walls of the first arc plate 1 and the second arc plate 2. Limiting plates 17 for fixed connection with the pile legs 43 are provided in the limiting grooves 16. By driving the second support base 4 and the second guide bar 8 to rotate synchronously, the second support base 4 moves relative to the second arc plate 2. The second support base 4 can drive the ends of the two pile legs 43 to stick together through the first support base 3 and the first arc plate 1. Then, the position of the second arc plate 2 is limited by the stop limiting component, so that the second arc plate 2 is fixed relative to the second support base 4, avoiding the second support base 4 from rotating and shaking relative to the second arc plate 2 due to non-human factors, and the stop limiting component is used to limit the position of the second arc plate 2. The component no longer limits the position of the second guide bar 8, allowing it to slide within the guide groove 5. During welding, there is no wobbling between the two pile legs 43, and the worker can weld at the connection between the two pile legs 43 using welding equipment. When the plug-in fixing structure obscures part of the connection between the two pile legs 43, since the second guide bar 8 can slide within the guide groove 5, the worker can drive the second guide bar 8 to slide within the guide groove 5. The second guide bar 8, through the plug-in fixing structure, drives the first guide bar 6 to slide within the guide groove 5 located on the first support seat 3, thereby changing the position of the plug-in fixing structure. This ensures that welding can be performed at different positions on the connection between the two pile legs 43. During welding, there is no wobbling between the two pile legs 43, improving the accuracy and quality of the pile leg 43 splicing.

[0023] In some optional specific embodiments, such as Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the insertion and fixing structure includes at least one limiting sleeve 9 fixedly installed on the second guide bar 8. The first guide bar 6 has at least one insertion rod 7 on the side facing the second guide bar 8, and the number of insertion rods 7 and limiting sleeves 9 are the same. The limiting sleeve 9 is equipped with a fixing unit that cooperates with the insertion rod 7. The first guide bar 6 is equipped with a synchronous sliding structure for driving the insertion rod 7 to move vertically. The synchronous sliding structure includes a fixing sleeve 10 sleeved on the outside of the insertion rod 7, and the fixing sleeve 10 is fixedly connected to the first guide bar 6. The first guide bar 6 faces the second guide bar 8. A first movable frame 11 is provided on one side of the strip 8. A fixed sleeve 10 passes through the first movable frame 11. At least one rectangular hole 12 is provided on the inner wall of the fixed sleeve 10. A connecting block 13 is provided in the rectangular hole 12. The connecting block 13 is fixedly connected to the insertion rod 7, and the connecting block 13 is fixedly connected to the first movable frame 11. One end of one of the first movable frames 11 is fixedly connected to a first insertion block 14, and the other end of the first movable frame 11 is provided with a first slot 15, and the first insertion block 14 is located in the corresponding first slot 15. The fixed unit package The device includes at least one first support portion 21 fixedly mounted on the limiting sleeve 9. A locking pin 24 passes through the first support portion 21. An elastic element for applying tension to the locking pin 24 is installed on the first support portion 21. A positioning plate 23 passes through the limiting sleeve 9. A positioning hole 22 is provided on the insertion rod 7. The bottom end of the insertion rod 7 is located inside the corresponding limiting sleeve 9, and the positioning plate 23 passes through the corresponding positioning hole 22. The end of the locking pin 24 passes through the positioning plate 23. The elastic element includes a fixing disc 25 fixedly mounted on the end of the locking pin 24 away from the positioning plate 23. A tension spring 26 is sleeved on the outside of the locking column 24. The two ends of the tension spring 26 are fixedly connected to the first support part 21 and the fixing plate 25 respectively. The mounting part includes a mounting plate 18 that is fixedly installed at both ends of one of the first arc plate 1 and one of the second arc plate 2 respectively. The two ends of the other first arc plate 1 and the other second arc plate 2 are respectively provided with mounting grooves 19. The mounting plate 18 is located in the corresponding mounting groove 19, and the mounting plate 18 is connected to the corresponding first arc plate 1 or second arc plate 2 by bolts 20. The operator drives the two first arc-shaped plates 1 toward the end of the pile leg 43, so that the limiting plate 17 is inserted into the corresponding limiting groove 16, and the mounting plate 18 on the first arc-shaped plate 1 is inserted into the mounting groove 19 on the other first arc-shaped plate 1. The operator fixes the mounting plate 18 with bolts 20, so that the mounting plate 18 is fixed in the mounting groove 19, thus fixing the two first arc-shaped plates 1 to the end of the pile leg 43. Similarly, the two second arc-shaped plates 2 are fixed to the other end of the pile leg 43. When the two first arc-shaped plates 1 are fixedly connected together, the first insert 14 on the first movable frame 11 is inserted into the first slot 15 on the other first movable frame 11, thus fixing the two first movable frames 11 together. When it is necessary to fix the first guide bar 6 and the second guide bar 8 together, the operator drives the two... The first movable frame 11 moves synchronously. The first movable frame 11 drives the insertion rod 7 to move through the connecting block 13, so that the end of the insertion rod 7 is inserted into the limiting sleeve 9, and the side of the connecting block 13 facing the limiting sleeve 9 contacts the inner wall of the rectangular hole 12. The operator drives the fixed plate 25 and the locking post 24 to move. The tension spring 26 is in a stretched state to prevent the end of the locking post 24 from obstructing the positioning plate 23 from passing through the limiting sleeve 9. The operator drives the positioning plate 23 to pass through the limiting sleeve 9, and the positioning plate 23 passes through the positioning hole 22 on the insertion rod 7. The operator releases the fixed plate 25, and the tension spring 26 drives the fixed plate 25 and the locking post 24 to move, so that the end of the locking post 24 passes through the positioning plate 23, so that the positioning plate 23 is fixed relative to the limiting sleeve 9, thereby fixing the insertion rod 7 relative to the limiting sleeve 9, and thus fixing the first guide strip 6 relative to the second guide strip 8.

[0024] In some optional specific embodiments, such as Figure 5 , Figure 6 and Figure 8As shown, the first guide bar 6 and the second guide bar 8 are respectively rotatably connected to the side of their proximity, and the ball bearings 27 are in contact with the inner wall of the guide groove 5. The stop and limit assembly includes a support block 28 fixedly installed on the side of the second support base 4 away from the second arc plate 2. A second movable frame 29 is slidably sleeved on the outside of the support block 28. A support plate 30 is fixedly installed on the second guide bar 8. A first stop groove 32 is opened on the support plate 30. A first stop block 31 that matches the first stop groove 32 is fixedly installed on the second movable frame 29. A fixed seat 33 is provided on the side of the second arc plate 2 away from the first arc plate 1. A plurality of connecting posts 34 are fixedly installed on the fixed seat 33, and the connecting posts 34 and the second arc plate 1 are connected to the second arc plate 2. 2. Fixed connection: The fixed base 33 is provided with several second stop grooves 35. The second movable frame 29 is fixedly installed with a second stop block 36 that is adapted to the second stop groove 35. The second movable frame 29 is installed with a position locking unit that is adapted to the support block 28. The position locking unit includes a second support part 37 fixedly installed on the second movable frame 29. A second insert 38 passes through the second support part 37. The support block 28 is provided with two second slots 39. The end of the second insert 38 is located in one of the second slots 39. The second movable frame 29 is fixedly installed with a fixed frame 40. The second insert 38 and the fixed frame 40 are connected by a compression spring 41. The second insert 38 is fixedly installed with a handle 42. When the first stop block 31 is located within the first stop groove 32 and the second stop block 36 is not located within a corresponding second stop groove 35, the first stop block 31 limits the position of the first stop groove 32 and the support plate 30, thereby fixing the second guide bar 8 relative to the second movable frame 29 and the second support base 4, preventing the second guide bar 8 from sliding within the guide groove 5. Since the second stop block 36 is not located within a corresponding second stop groove 35, the second support base 4 and the second movable frame 29 can rotate relative to the second arc plate 2. When it is necessary for the second support base 4 to be fixed relative to the second arc plate 2 and the second guide bar 8 to slide relative to the guide groove 5, the operator drives the second insert block 38 to move via the handle 42. The compression spring 41 is in a compressed state, causing the end of the second insert block 38 to disengage from a corresponding second slot 39. The operator then drives the second movable frame 29 relative to the support block 28 and the second support base 29. The seat 4 moves horizontally so that the second stop block 36 is inserted into a corresponding second stop groove 35, and the first stop block 31 slides out from the first stop groove 32, so that the second support seat 4 and the second movable frame 29 are fixed relative to the fixed seat 33 and the second arc plate 2, and the support plate 30 and the second guide bar 8 can rotate relative to the second support seat 4. At this time, the end of the second insert 38 moves to one side of the other second slot 39. The operator releases the handle 42, and the compression spring 41 drives the second insert 38 to move so that the end of the second insert 38 is inserted into the corresponding second slot 39, so that the second movable frame 29 is fixed relative to the support block 28 and the second support seat 4. When the second guide bar 8 and the first guide bar 6 slide in the corresponding guide groove 5, the ball 27 rolls on the inner wall of the guide groove 5. Through the design of the ball 27, the resistance encountered by the second guide bar 8 and the first guide bar 6 when sliding is reduced.

[0025] Working principle: Before splicing the pile legs 43, the workers weld two limiting plates 17 to both ends of the pile legs 43, with adjacent limiting plates 17 located on both sides of the pile legs 43. The workers place two first arc-shaped plates 1 at one end of the pile legs 43 and two second arc-shaped plates 2 at the other end of the pile legs 43. The workers then drive the first arc-shaped plates 1 and the second arc-shaped plates 2 to move, so that the limiting plates 17 are inserted into the corresponding limiting grooves 16. The two first arc-shaped plates 1 are fixed together by the mounting brackets, and then the two second arc-shaped plates 2 are fixed together by the mounting brackets. The two pile legs 43, after being installed with the splicing positioning fixture, are then lifted by a ship crane. Leg 43 is lifted to a preset position, and the second guide bar 8 and the corresponding first guide bar 6 are fixed together by a plug-in fixing structure. A stop and limit component limits the position of the second guide bar 8, fixing it relative to the second support base 4. However, the stop and limit component does not limit the position of the second support base 4, allowing it to rotate relative to the second arc-shaped plate 2. The operator drives the second support base 4 and the second guide bar 8 to rotate synchronously. The second guide bar 8 drives the first guide bar 6 to slide within the two guide grooves 5 via the plug-in fixing structure. Since the connection between the second support base 4 and the second arc-shaped plate 2 is a threaded connection... As the second support base 4 rotates, it moves relative to the second arc-shaped plate 2. The second support base 4, through the first support base 3 and the first arc-shaped plate 1, drives the ends of the two pile legs 43 to press tightly together. Then, the stop and limit assembly limits the position of the second arc-shaped plate 2, fixing it relative to the second support base 4 and preventing rotational wobbling of the second support base 4 relative to the second arc-shaped plate 2 due to non-human factors. Furthermore, the stop and limit assembly no longer limits the position of the second guide strip 8, allowing it to slide within the guide groove 5. During welding, there will be no wobbling between the two pile legs 43, ensuring the safety of workers. The operator can then weld at the connection between the two pile legs 43 using welding equipment. When the plug-in fixing structure obscures part of the connection between the two pile legs 43, the second guide bar 8 can slide in the guide groove 5. The operator drives the second guide bar 8 to slide in the guide groove 5, and the second guide bar 8 drives the first guide bar 6 to slide in the guide groove 5 located on the first support seat 3 through the plug-in fixing structure. This changes the position of the plug-in fixing structure, ensuring that welding can be performed at different positions on the connection between the two pile legs 43. During the welding process, the two pile legs 43 will not wobble, improving the accuracy and quality of the pile leg 43 splicing. The operator drives the two first arc-shaped plates 1 toward the end of the pile leg 43, so that the limiting plate 17 is inserted into the corresponding limiting groove 16, and the mounting plate 18 on the first arc-shaped plate 1 is inserted into the mounting groove 19 on the other first arc-shaped plate 1. The operator fixes the mounting plate 18 with bolts 20, so that the mounting plate 18 is fixed in the mounting groove 19, thus fixing the two first arc-shaped plates 1 to the end of the pile leg 43. Similarly, the two second arc-shaped plates 2 are fixed to the other end of the pile leg 43. When the two first arc-shaped plates 1 are fixedly connected together, the first insert 14 on the first movable frame 11 is inserted into the first slot 15 on the other first movable frame 11, thus fixing the two first movable frames 11 together. When it is necessary to fix the first guide bar 6 and the second guide bar 8 together, the operator drives the two... The first movable frame 11 moves synchronously. The first movable frame 11 drives the insertion rod 7 to move through the connecting block 13, so that the end of the insertion rod 7 is inserted into the limiting sleeve 9, and the side of the connecting block 13 facing the limiting sleeve 9 contacts the inner wall of the rectangular hole 12. The operator drives the fixed plate 25 and the locking column 24 to move. The tension spring 26 is in a stretched state to prevent the end of the locking column 24 from obstructing the positioning plate 23 from passing through the limiting sleeve 9. The operator drives the positioning plate 23 to pass through the limiting sleeve 9, and the positioning plate 23 passes through the positioning hole 22 on the insertion rod 7. The operator releases the fixed plate 25, and the tension spring 26 drives the fixed plate 25 and the locking column 24 to move, so that the end of the locking column 24 passes through the positioning plate 23, so that the positioning plate 23 is fixed relative to the limiting sleeve 9, thereby fixing the insertion rod 7 relative to the limiting sleeve 9, and thus fixing the first guide bar 6 relative to the second guide bar 8. When the first stop block 31 is located within the first stop groove 32 and the second stop block 36 is not located within a corresponding second stop groove 35, the first stop block 31 limits the position of the first stop groove 32 and the support plate 30, thereby fixing the second guide bar 8 relative to the second movable frame 29 and the second support base 4, preventing the second guide bar 8 from sliding within the guide groove 5. Since the second stop block 36 is not located within a corresponding second stop groove 35, the second support base 4 and the second movable frame 29 can rotate relative to the second arc plate 2. When it is necessary for the second support base 4 to be fixed relative to the second arc plate 2 and the second guide bar 8 to slide relative to the guide groove 5, the operator drives the second insert block 38 to move via the handle 42. The compression spring 41 is in a compressed state, causing the end of the second insert block 38 to disengage from a corresponding second slot 39. The operator then drives the second movable frame 29 relative to the support block 28 and the second support base 29. The seat 4 moves horizontally so that the second stop block 36 is inserted into a corresponding second stop groove 35, and the first stop block 31 slides out from the first stop groove 32, so that the second support seat 4 and the second movable frame 29 are fixed relative to the fixed seat 33 and the second arc plate 2, and the support plate 30 and the second guide bar 8 can rotate relative to the second support seat 4. At this time, the end of the second insert 38 moves to one side of the other second slot 39. The operator releases the handle 42, and the compression spring 41 drives the second insert 38 to move so that the end of the second insert 38 is inserted into the corresponding second slot 39, so that the second movable frame 29 is fixed relative to the support block 28 and the second support seat 4. When the second guide bar 8 and the first guide bar 6 slide in the corresponding guide groove 5, the ball 27 rolls on the inner wall of the guide groove 5. Through the design of the ball 27, the resistance encountered by the second guide bar 8 and the first guide bar 6 when sliding is reduced.
