Description

Technical Field

[0001] This application relates to the technical field of submerged arc welding, and in particular to a submerged arc horizontal welding machine for offshore wind turbine monopiles. Background Technology

[0002] Currently, with the development of offshore wind power, the application of large-diameter steel pipe pile foundations is becoming increasingly common. In the manufacturing process of steel pipe piles, steel plates are rolled into cylindrical pipe sections using a plate rolling machine, and then the pipe sections are butt-welded together. However, due to the limited size of the steel plates, they are usually welded using a submerged arc welding machine before being rolled into pipe sections, and then the pipe sections are welded together.

[0003] Reference Figure 1 The submerged arc horizontal welding machine mainly includes a welding mechanism 1, a flux holding mechanism 2, and a flux tank 3. A discharge pipe is connected to the flux tank 3, pouring the flux onto the flux holding mechanism 2. The horizontal welding machine is mounted on the base material to be welded via a track. The welding mechanism 1 moves along the track, and the flux holding mechanism 2 moves synchronously, performing welding operations simultaneously. During the welding process, not all the flux on the flux holding mechanism 2 participates in the reaction. Therefore, a recovery pipe 5 is installed on the flux tank 3. A pump or similar device generates suction to draw the flux from the flux holding mechanism 2 back into the flux tank 3 for recycling.

[0004] During the welding process, flaky slag will remain at the transverse seam after welding. This slag may also be sucked into the flux tank 3 by the recovery pipe 5, which will affect the quality of the subsequent flux and is not conducive to subsequent welding. Summary of the Invention

[0005] To reduce the amount of welding slag adsorbed in the flux tank, this application provides a submerged arc horizontal welding machine for offshore wind power monopiles.

[0006] This application provides a submerged arc welding machine for offshore wind turbine monopiles, employing the following technical solution:

[0007] A submerged arc horizontal welding machine for welding monopiles in offshore wind power includes a welding mechanism, a flux holding mechanism, a flux bin, and a filtering mechanism located below the flux holding mechanism. A recovery pipe connects the filtering mechanism and the flux bin. The filtering mechanism includes a material receiving bin, a filter element disposed within the material receiving bin for receiving materials falling from the flux holding mechanism, and a cleaning element installed on the material receiving bin. A partition is provided inside the material receiving bin, dividing the bin into a first chamber and a second chamber. The recovery pipe is connected to the first chamber. The filter element is located at the opening of the first chamber. The cleaning element is used to sweep materials on the surface of the filter element into the second chamber. The filter element includes a mounting plate connected to the first chamber and a filter plate slidably connected to the mounting plate. Filter grooves are spaced apart on the filter plate. A trigger element is installed on the material receiving bin, which drives the filter plate to slide back and forth on the mounting plate.

[0008] By adopting the above technical solution, during welding, the flux on the flux holding mechanism can fall onto the filter element. The filter plate can reciprocate through the trigger element, so that the flux can fall into the first chamber. The cleaning element scrapes the flaky slag into the second chamber, thereby reducing the situation where slag is sucked into the flux chamber.

[0009] Optionally, the mounting plate has a mounting groove, the filter plate is installed in the mounting groove, the inner wall of the mounting groove has a insertion groove, the end of the filter plate is slidably inserted into the insertion groove, and an elastic element is connected between one end of the filter plate and the insertion groove. A sliding post is provided at the end of the filter plate away from the elastic element, and the sliding post passes through the side wall of the mounting plate and abuts against the trigger element. The trigger element can intermittently drive the sliding post to slide towards the elastic element.

[0010] By adopting the above technical solution, the filter plate is slidably inserted into the insertion slot. When the trigger drives the filter plate to slide, the elastic element is compressed, thereby providing the reset force of the filter plate and realizing the reciprocating motion of the filter plate.

[0011] Optionally, the trigger includes a rotating disk rotatably connected to the material receiving bin, the rotating disk having an abutment groove, the end of the sliding column abutting in the abutment groove, and the depth of the abutment groove gradually decreasing from the middle to both sides.

[0012] By adopting the above technical solution, an abutment groove is provided on the rotating disk, and the end of the sliding column can abut in the abutment groove. When the rotating disk rotates, the inner wall of the abutment groove can drive the sliding column to slide. The rotation of the rotating disk can drive the sliding column and the abutment groove to contact intermittently, thereby driving the filter plate to slide back and forth.

[0013] Optionally, the cleaning component includes a rotating rod rotatably connected to the material receiving bin, a power component for driving the rotating rod to rotate, and a cleaning plate connected to the outer wall of the rotating rod. The mounting plate and the filter plate have an arc structure, and when the rotating rod rotates, the cleaning plate can abut against the surface of the filter plate.

[0014] By adopting the above technical solution, when the rotating rod rotates, it drives the cleaning plate to move, which can sweep the welding slag on the surface of the filter plate into the second chamber.

[0015] Optionally, the cleaning plate is provided with bristles on the side away from the rotating rod.

[0016] By adopting the above technical solutions, the cleaning effect can be improved.

[0017] Optionally, the filter plate is further provided with slots spaced apart, the slots being located between two adjacent filter slots. A connecting rod is rotatably connected to the filter plate, the connecting rod passing through all the slots, and an extension strip is installed on the outer wall of the connecting rod, the extension strip extending into the slots. A linkage structure is provided between the connecting rod and the cleaning plate. When the cleaning plate begins to contact the filter plate, the linkage structure can drive the connecting rod to rotate, causing the extension strip to move downwards. A reset member is also installed on the filter plate. When the cleaning plate and the connecting rod disengage, the reset member drives the extension strip to re-enter the slots.

[0018] By adopting the above technical solution, when the extension rod is located in the slot, the welding slag is not easy to fall from the slot into the first cavity. When the cleaning plate moves to the filter plate, the extension bar moves downward and the slot is exposed, so that the flux can also fall downward from the slot, while the welding slag is not easy to fall from the slot, thereby improving the separation effect of flux and welding slag.

[0019] Optionally, the linkage structure includes linkage wheels installed at both ends of the connecting rod and a linkage plate installed on the sweeping plate. The linkage plate has an arc-shaped structure, and when the sweeping plate moves, the linkage wheels can abut against the linkage plate.

[0020] By adopting the above technical solution, when the cleaning plate moves, the linkage wheel abuts against the linkage plate, thereby driving the linkage wheel to rotate, which in turn causes the extension strip to move downward and separate from the groove.

[0021] Optionally, the reset member includes an elastic sheet mounted on the surface of the filter plate, the elastic sheet abutting against the lower surface of the extension strip.

[0022] By adopting the above technical solution, the extension strip can be driven to reset and re-enter the slot under the action of the elastic sheet.

[0023] In summary, this application includes at least one of the following beneficial effects:

[0024] 1. The flux can fall into the filtration mechanism and be filtered through the filter plate. The flux can fall into the first chamber, while the slag can be swept into the second chamber through the cleaning component, thereby separating the flux and slag and improving the purity of the recovered flux.

[0032] The following is in conjunction with the appendix Figure 2-6 This application will be described in further detail.

[0033] This application discloses a submerged arc horizontal welding machine for welding monopiles in offshore wind power, referring to... Figure 2The system includes a welding mechanism 1, a flux holding mechanism 2, and a flux tank 3. The flux holding mechanism 2 is a support belt, and the flux tank 3 is used to fill the flux. The flux is poured onto the flux holding mechanism 2 through a pipe, and then the welding mechanism 1 welds the transverse seam. During the welding process, the support belt of the flux holding mechanism 2 can move, thereby discharging the flux on the surface of the support belt from one end of the support belt. The submerged arc horizontal welding machine also includes a filtering mechanism 4, which is installed below the flux holding mechanism 2. The flux on the flux holding mechanism 2 after welding can fall into the filtering mechanism 4.

[0034] Reference Figure 2 and Figure 3 The filtration mechanism 4 includes a material receiving bin 41, a filter element 42 installed inside the material receiving bin 41, and a cleaning element 43 installed on the material receiving bin 41. The material receiving bin 41 is fixed to the frame of the flux holding mechanism 2 by welding or bolts, and is located below the flux holding mechanism 2. The middle of the opening of the material receiving bin 41 is located below the flux drop point of the welding holding mechanism. During welding, the flux on the flux holding mechanism 2 can fall into the material receiving bin 41.

[0035] Combination Figure 4 A partition 6 is vertically fixed in the material receiving bin 41, dividing the space inside the bin 41 into a first chamber 7 and a second chamber 8. A filter element 42 is installed in the first chamber 7. During welding, the first chamber 7 is located on the side closer to the base material. The filter element 42 separates the flux and slag. The flux can fall into the first chamber 7 through the filter element 42, while the slag is retained on the filter element 42. Then, the cleaning element 43 sweeps the slag on the filter element 42 into the second chamber 8 for collection. A recovery pipe 5 is also installed between the flux bin 3 and the material receiving bin 41. The recovery pipe 5 is connected to the first chamber 7, thereby recovering the flux in the first chamber 7 into the flux bin 3.

[0036] Furthermore, refer to Figure 4 and Figure 5 The filter element 42 includes a mounting plate 421 and a filter plate 422 slidably mounted on the mounting plate 421. Filter grooves 423 are spaced apart on the filter plate 422. The mounting plate 421 has an upward-facing arc-shaped structure, with one side connected to the inner wall of the material receiving bin 41 and the other side connected to the upper end of the partition plate 6. A mounting groove 10 is provided on the mounting plate 421, and the filter plate 422 is installed in the mounting groove 10. The filter plate 422 also has an arc-shaped structure, and its surface is flush with the surface of the mounting plate 421. A trigger 9 is also installed on the material receiving bin 41. The trigger 9 drives the filter plate 422 to reciprocate, causing flux to fall onto the filter plate 422. The reciprocating motion of the filter plate 422 facilitates the flux falling into the first cavity 7.

[0037] In a further embodiment, symmetrical insertion slots 11 are provided on the inner wall of the mounting groove 10. Both ends of the filter plate 422 are inserted into the insertion slots 11. Preferably, both ends of the filter plate 422 have a stepped structure. One end of the filter plate 422 is equipped with an elastic element 12, which is a spring, and multiple springs are provided. The other end of the spring is connected to the inner end face of the insertion slot 11. The end of the filter plate 422 away from the elastic element 12 is connected to a sliding post 13, which slides through the end face of the mounting plate 421. One end of the sliding post 13 can abut against the trigger 9. The trigger 9 drives the sliding post 13 to slide towards the elastic element 12, and the elastic element 12 is compressed.

[0038] Furthermore, the trigger 9 includes a rotating disk 91 rotatably mounted on the material receiving bin 41, and the rotating disk 91 has an abutment groove 14. The inner wall of the abutment groove 14 is inclined, that is, the depth of the abutment groove 14 gradually becomes shallower from the middle to both sides. Under the action of the elastic member 12, the end of the sliding column 13 abuts against the rotating disk 91. When the rotating disk 91 moves to a certain point, the end of the sliding column 13 can abut in the abutment groove 14. As the rotating disk 91 continues to rotate, the sliding column 13 can be compressed. Multiple abutment grooves 14 can be evenly arranged along the circumference of the rotating disk 91. With the cooperation of the rotating disk 91 and the sliding column 13, the filter plate 422 can be driven to reciprocate. The rotating disk 91 is rotatably connected to the material receiving bin 41 by bearings or the like. Preferably, the end face of the mounting plate 421 abuts against the surface of the rotating disk 91. The rotating disk 91 is rotatably connected to the material receiving bin by bearings or the like, and the rotating disk 91 can be driven to rotate by a motor or the like.

[0039] In a further embodiment, refer to Figure 3 The cleaning component 43 includes a rotating rod 432 rotatably mounted on the material receiving bin 41, a power component 431 for driving the rotating rod 432 to rotate, and a cleaning plate 433 mounted on the outer wall of the rotating rod 432. The cleaning plate 433 has a hollow structure. The rotating rod 432 and the mounting plate 421 are coaxially arranged so that the cleaning plate 433 can abut against the surface of the mounting plate 421 when it moves. Preferably, bristles are evenly installed on the side of the cleaning plate 433 away from the rotating rod 432, which is more conducive to sweeping the welding slag on the surface of the filter plate 422 into the second cavity 8.

[0040] Furthermore, refer to Figure 5 and Figure 6The distance between two adjacent filter grooves 423 on the filter plate 422 is two to three times the width of the filter groove 423. Weld slag is generally in the form of flakes or strips, making it difficult for it to fall from the filter grooves 423 into the first chamber 7 during filtration. The arc-shaped structure of the mounting plate 421 and the filter plate 422 also prevents weld slag from falling from the filter grooves 423. A slot 15 is provided on the filter plate 422, located between two adjacent filter grooves 423. A connecting rod 16 is rotatably connected to the filter plate 422, passing through all the slots 15, and located on the side of the filter plate 422 that first contacts the cleaning plate 433. An extension strip 17 is also installed on the connecting rod 16, located within the slots 15, preventing weld slag from falling from the slots 15. A linkage structure 18 is also installed between the connecting rod 16 and the cleaning plate 433. When the cleaning plate 433 begins to contact the filter plate 422, the linkage structure 18 drives the connecting rod 16 to rotate, thereby causing the extension bar 17 to move downwards. The flux on the filter plate 422 can then fall downwards from the slot 15, while the welding slag remains on the filter plate 422. As the cleaning plate 433 continues to move, it can sweep the welding slag on the filter plate 422 into the second cavity 8. The side wall of the extension bar 17 has an arc-shaped structure, which facilitates the downward falling of the flux on the filter plate 422 when the extension bar 17 moves downwards.

[0041] In a further embodiment, the linkage structure 18 includes a linkage wheel 181 mounted on the end of the connecting rod 16 and a linkage plate 182 mounted on the cleaning plate 433. Preferably, both ends of the connecting rod 16 are fixed with linkage wheels 181, and the filter plate 422 has a cavity corresponding to the position of the linkage wheel 181 to accommodate the linkage wheel 181. The bottom surface of the linkage plate 182 is arc-shaped and rough. When the cleaning plate 433 moves, the linkage wheel 181 can abut against the linkage plate 182, so that the movement of the linkage plate 182 can drive the linkage wheel 181 to rotate, thereby driving the connecting rod 16 to rotate. A reset member 19 is also installed on the filter plate 422. When the linkage plate 182 and the linkage wheel 181 are disengaged, the extension strip 17 can be reset under the action of the reset member 19. Preferably, the reset member 19 is an elastic sheet 191 installed on the bottom surface of the filter plate 422. The elastic sheet 191 abuts against the lower end of the extension strip 17. When the extension strip 17 moves downward, the elastic sheet 191 deforms downward, thereby providing a reset force for the extension strip 17.

[0042] The implementation principle of a submerged arc horizontal welding machine for offshore wind turbine monopile welding according to an embodiment of this application is as follows: During welding, the flux on the flux holding mechanism 2 can fall onto the filter plate 422. The filter plate 422 continuously reciprocates, making it easier for the flux to fall into the first chamber 7. The cleaning plate 433 continuously rotates, which can sweep the welding slag on the surface of the filter plate 422 into the second chamber 8. Furthermore, during the rotation of the cleaning plate 433, the extension strip 17 can move downward, allowing the flux to fall downward from the slot 15, thereby improving the filtration effect of the flux.

[0043] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
