Description

Technical Field

[0001] The invention relates to the technical field of welding, and in particular to a steel structure welding guide alignment device and method for manufacturing a hull structure. Background Art

[0002] For example, the patent document with publication number CN116511777A, the invention name is a steel structure welding guide alignment device for hull structure manufacturing. The invention can freely adjust the curvature of a plurality of guide frames connected end to end to adapt to the guidance of straight or curved welds. Due to the mutual engagement of the locking teeth and the positioning teeth, the adjacent guide frames can be prevented from bending arbitrarily under the restriction of the rotating shaft, the clamping slider and the positioning assembly to fix the overall curvature of the guide frame, and then it can be adapted to one side of the weld through two fixing components to facilitate the continuous movement of the guiding welding gun.

[0003] For example, the patent document with publication number CN118081158B, the invention name is a petrochemical pipeline welding device with automatic alignment function. The invention describes a petrochemical pipeline welding device with automatic alignment function, which automatically aligns the petrochemical pipeline through the cooperation of a hoist, a positioning alignment structure, a clamp, and a welding structure, thereby reducing the displacement of the petrochemical pipeline during the welding process, resulting in misalignment at the welding interface, affecting the welding quality of the petrochemical pipeline, affecting the use of the petrochemical pipeline, and shielding the petrochemical pipeline weld through the cooperation of a lifting component and a welding guide component to prevent wind and sand or other external factors from affecting the welding effect.

[0004] During the hull welding process, in order to shape the hull, the steel plates need to be precisely butted and welded to the skeleton of the keel tightly. If the gap between the steel plates is too large during welding, it may cause problems such as cold welding or structural installation misalignment. Due to the different angles and shapes of the spliced ​​ship plates, the angle difference between the welded ship plates is large, which further increases the difficulty of alignment.

[0010] Among them, the locking mechanism includes a clamping block, a friction plate is arranged on the top of the inner wall of the clamping block, two first round rods are arranged inside the clamping block, and half-ring blocks are rotatably installed on the outer surfaces of the two first round rods. A support rod for limiting the rotation angle of the half-ring block is arranged on the inner wall of the clamping block and on one side of the first round rod.

[0011] The semi-ring block is semicircular in shape, and a plurality of friction grooves are provided on the outer surface of the semi-ring block, and the first round rod deviates from the center of the semi-ring block.

[0012] Wherein, the alignment assembly includes an alignment mechanism, which includes a center column, and the center column is installed in a center hole by bolts.

[0016] The present invention also provides a method for using a steel structure welding guide alignment device for ship hull structure manufacturing, and the specific method for using the device is as follows:

[0017] S1. When welding the hull, steel plates need to be welded on the skeleton to shape the hull. When welding the steel plates, the welded steel plates need to be aligned tightly to ensure that the welded hull will not be cold welded due to too large a gap or cause other structures to be installed misaligned due to too large a gap. Therefore, when welding, the two casings need to correspond to the two ship boards that need to be welded, and then the vacuum pump inside the casing extracts the gas inside the adsorption plate through the ventilation pipe, and the adsorption plate corresponds to the ship board. When the gas inside the adsorption plate is extracted, it will be firmly adsorbed on the ship board;

[0018] S2. After the adsorption plate is adsorbed on the shipboard, the fine adjustment mechanism or alignment mechanism is selected to correct the angle according to whether the two butted steel plates have an angle deviation. When the two butted steel plates are in the same plane, the take-up mechanism reels in the rope to pull the support frame to move, and the support frame drives the butted steel plates to move through the adsorption plate, so that the two steel plates are butted together;

[0019] S3. When the two butted ship plates have an arc, a fine-tuning mechanism is used to fine-tune the angle of the ship plates. By adjusting the angle of the ship plates, the welding gap between the two ship plates is reduced. When the angle between the two butted ship plates is large, an alignment mechanism is used to control the butt angle between the two ship plates.

[0020] S4. When two butted ship plates need to be clamped at the corners for butt welding, the user can clamp the two locking mechanisms at the corners of the ship plates respectively, and then use the take-up mechanism to reel in the rope to drive the two casings to move relative to each other, and then the casing drives the locking mechanism to move through the outer shell, and the set locking mechanism can clamp ship plates of different thicknesses as needed.

[0021] In summary, the technical effects and advantages of the present invention are as follows:

[0022] In the present invention, when the angle between the two ship plates is large, the extrusion tube can be rotated on the outer surface of the second round rod, and under the action of the cable winding, the mounting ring is driven to move toward the angle of the ship plates, thereby accurately adjusting the angle of the ship plates to ensure that they are in the correct docking position. By applying appropriate pressure to the ship plates through the extrusion tube, the welding gap can be reduced to avoid the occurrence of cold welding. At the same time, good angle alignment helps to evenly distribute welding stress and prevent the problem of excessive local stress.

[0023] In the present invention, for curved or irregularly shaped shipboards, the friction cylinder and the cylinder continuously contact the surface of the shipboard, and the position of the shipboard is adjusted as the cable is wound, so that precise alignment can be achieved even in complex shapes. By rotating the threaded rod, the support block is pushed downward, and the tripod is rotated inside the connecting block to maintain the relative angle between the shipboards and prevent angle deviation during the alignment process. The design of the friction cylinder and the cylinder allows them to rotate when contacting the shipboard, avoiding excessive extrusion due to static pressure, thereby protecting the shipboard from unnecessary damage or deformation. The tripod is in the shape of the letter "Y", providing a larger contact area for the friction cylinder and the cylinder, ensuring uniform contact of the shipboard over the entire length, and is suitable for shipboards of various shapes and sizes, increasing its application range and versatility.

[0024] In the present invention, the ship plate is clamped between the semi-ring block and the friction plate, and the traction force generated when the cable is wound is used to drive the clamping block to move, so that the semi-ring block rotates closely against the surface of the ship plate and gradually squeezes the ship plate, thereby achieving precise correction and alignment. The progressive pressure between the semi-ring block and the friction plate can effectively prevent the ship plate from being deformed unnecessarily due to excessive squeezing, while ensuring stability during the correction process. The friction grooves on the surface of the semi-ring block increase the friction between it and the ship plate, which helps to better fix the ship plate and ensure that it will not slide or shift during the correction process. As the first round rod moves away from the center of the semi-ring block, the distance between the semi-ring block and the friction plate gradually decreases, and finally the ship plate is tightly fixed between the two, ensuring a good contact surface, which is beneficial to subsequent welding operations. In this way, the corrected ship plates can be more closely docked together, reducing the possibility of cold welding, and evenly distributing welding stress, avoiding the problem of excessive local stress, and improving welding quality.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example 1, Reference Figures 1 to 11 A steel structure welding guide alignment device for ship hull structure manufacturing shown in the figure comprises two housings 1, both housings 1 are provided with a driving motor and an air suction pump, both housings 1 are provided with a wire take-up mechanism 5 for aligning the welded ship plates at the lower end, a mounting mechanism 11 is provided between the two wire take-up mechanisms 5, an alignment component for fine-tuning the ship plate welding angle is provided inside the mounting mechanism 11, both housings 1 are provided with a shell 2 on the outer surface, and both housings 2 are provided with a locking mechanism 3 for clamping and aligning the ship plates on the outer surface;

[0040] A support frame 4 is provided at the bottom of the two casings 1, and a plurality of fixed locking tubes 9 are provided inside the two support frames 4. Adsorption plates 8 are provided at the bottoms of the plurality of fixed locking tubes 9, and ventilation pipes 7 connected to the suction pump inside the casing 1 are provided at the upper ends of the plurality of fixed locking tubes 9.

[0041] It is worth noting that when welding the hull, steel plates need to be welded on the skeleton of the keel to shape the hull. When welding the steel plates, the welded steel plates need to be aligned tightly to ensure that the welded hull will not be poorly welded due to excessive gaps or cause other structures to be installed misaligned due to excessive gaps. Therefore, when welding, the two casings 1 need to correspond to the two ship boards that need to be welded, and then the vacuum pump inside the casing 1 extracts the gas inside the adsorption disk 8 through the ventilation pipe 7, and the adsorption disk 8 corresponds to the ship board. When the gas inside the adsorption disk 8 is extracted, it will be firmly adsorbed on the ship board;

[0042] After the adsorption plate 8 is adsorbed on the shipboard, the fine adjustment mechanism 6 or the alignment mechanism 10 is selected to correct the angle according to whether the two butted steel plates have an angle deviation. When the two butted steel plates are in the same plane, the take-up mechanism 5 reels in the rope to pull the support frame 4 to move, and the support frame 4 drives the butted steel plates to move through the adsorption plate 8, so that the two steel plates are butted together;

[0043] Among them, through the cooperation of the vacuum pump and the adsorption plate 8, it can be ensured that the steel plate is firmly fixed and tightly fitted, eliminating the risk of cold welding due to excessive gaps. The design of the fine-tuning mechanism 6 and the alignment mechanism 10 allows automatic correction of the angular deviation between the steel plates. The take-up mechanism 5 can quickly pull the support frame 4 by winding the rope, so that the two steel plates can be quickly and accurately docked together. When the adsorption plate 8 is adsorbed on the shipboard, it provides a stable support point for welding, maintaining stability during the welding process.

[0044] When the two butted ship plates have an arc, the fine-tuning mechanism 6 is used to fine-tune the angle of the ship plates, and the welding gap between the two ship plates is reduced by adjusting the angle of the ship plates. When the angle between the two butted ship plates is large, the alignment mechanism 10 is used to control the butt angle between the two ship plates.

[0045] Among them, by accurately adjusting the relative angle between the arc-shaped ship plates through the fine-tuning mechanism 6, the welding gap can be effectively reduced, ensuring that the welding points are closer, which is helpful to improve the welding strength and reduce the occurrence of cold welds. For the docking of ship plates with larger angles, the use of the alignment mechanism 10 can ensure that the two ship plates are docked at the correct angle, avoiding structural installation misalignment or stress concentration problems caused by angle deviation. The design of the fine-tuning mechanism 6 and the alignment mechanism 10 makes the angle adjustment process faster and more accurate.

[0046] When two butted ship plates need to be clamped at the corners for butt welding, the user can respectively clamp the two locking mechanisms 3 at the corners of the ship plates, and then use the take-up mechanism 5 to wind up the rope to drive the two casings 1 to move relative to each other, and then the casing 1 drives the locking mechanism 3 to move through the outer shell 2, and the set locking mechanism 3 can clamp ship plates of different thicknesses according to needs.

[0047] Among them, the locking mechanism 3 can be firmly fixed on the corners of the shipboard to ensure that the edges of the two shipboards are precisely aligned. The locking mechanism 3 can adjust the clamping force as needed to adapt to shipboards of different thicknesses and can be used for a variety of different welding tasks. Through the strong clamping of the locking mechanism 3, a stable foundation can be provided for the welding process, reducing the movement of the shipboard caused by external vibration or other factors.

[0048] Embodiment 2: Based on the wire-receiving mechanism 5 and the alignment assembly provided in Embodiment 1, this embodiment provides a further technical solution for the wire-receiving mechanism 5 and the alignment mechanism 10.

[0049] The wire-winding mechanism 5 includes a mounting shell 51, a wire drum 52 is arranged inside the mounting shell 51, and the wire drum 52 is fixedly mounted on the output shaft surface of the driving motor inside the casing 1. A through hole 55 is opened on one side of the mounting shell 51, and a locking clamp 53 is fixedly installed on one side of the mounting shell 51. A cable 54 is wound around the outer surface of the wire drum 52, and one end of the cable 54 passes through the through hole 55 and is fixedly connected to the locking clamp 53.

[0050] It is worth mentioning that when the gap between two ship plates that need to be welded is large, the driving motor inside the casing 1 drives the wire drum 52 to rotate, and the wire drum 52 reels the cable 54, and the two wire drums 52 are set to reel in the cable 54 at the same time. The traction force provided by the reeling of the cable 54 drives the ship plates to move, so that the two ship plates are aligned together to reduce the welding gap.

[0051] The mounting mechanism 11 includes a mounting ring 111 . Two wire holes are formed inside the mounting ring 111 , and the cables 54 pass through the wire holes. A center hole 112 is formed in the middle of the upper end of the mounting ring 111 .

[0052] The alignment assembly includes an alignment mechanism 10, which includes a center column 101. The center column 101 is installed in a center hole 112 by bolts. A gusset 102 is provided at the lower end of the center column 101. Second round rods 105 are provided on both sides of the gusset 102. The outer surfaces of the two second round rods 105 are provided with extruded tubes 103 that abut against the ship plate to correct the welding angle.

[0053] It is worth mentioning that when the angle between the two butted ship plates is large, the center column 101 is inserted into the center hole 112, and then as the cable 54 is wound, the angle plate 102 is driven to move through the mounting ring 111, and the angle plate 102 drives the mounting block 104 to resist the demolished ship plate. When the angle between the ship plate welding is large, the set extrusion tube 103 resists the ship plate and drives the mounting ring 111 to move toward the angle of the ship plate as the cable 54 is wound, and the set extrusion tube 103 rotates on the outer surface of the second round rod 105, and the extrusion tube 103 rotates on the outer surface of the ship plate to extrude the ship plate to be welded, so that the two ship plates to be welded can be angle-aligned and welded.

[0054] Among them, when the angle between the two ship boards is large, the extrusion tube 103 can be rotated on the outer surface of the second round rod 105, and under the action of the cable 54 being wound, the mounting ring 111 is driven to move toward the angle of the ship boards, thereby accurately adjusting the angle of the ship boards to ensure that they are in the correct docking position.

[0055] By applying appropriate pressure to the ship plate through the extrusion tube 103, the welding gap can be reduced and the occurrence of cold welding can be avoided. At the same time, good angle alignment helps to evenly distribute the welding stress and prevent the problem of excessive local stress.

[0056] The angle plate 102 is in the shape of a letter “V”, and a mounting block 104 is disposed on the inner wall of the angle plate 102 , and a wire groove 106 is formed on the inner wall of the mounting block 104 .

[0057] The mounting block 104 is used to abut against and polish the shipboard, and the interior of the wire groove 106 is used to place the polishing rod.

[0058] Embodiment 3: Based on the alignment assembly provided in Embodiment 1, this embodiment provides a further technical solution for the fine-tuning mechanism 6.

[0059] The alignment assembly includes a fine-tuning mechanism 6, which includes a support plate 61. Two threaded holes are symmetrically provided at the upper end of the support plate 61, and threaded rods 64 that penetrate the support plate 61 are provided inside the two threaded holes. A screw is provided at the upper end of the support plate 61, and the screw is located inside the center hole 112. Two connecting blocks 63 are symmetrically provided at the bottom of the support plate 61, and tripods 62 are rotatably installed inside the two connecting blocks 63. Two cylinders 65 are symmetrically rotatably installed at one end of the two tripods 62, and friction cylinders 66 are rotatably installed on the inner walls of the two tripods 62.

[0060] It is worth mentioning that when the two welded ship boards are arc-shaped or irregular in shape, in order to prevent the shrinking cable 54 from shrinking close to the ship board and to prevent the angles from being different during the alignment of the two ship boards, the support plate 61 is installed inside the mounting ring 111 through a screw, and then the user rotates the threaded rod 64. As the threaded rod 64 rotates, the connecting column 67 is pushed downward, and the connecting column 67 pushes the support block 69 downward. In order to ensure that the support block 69 moves downward, the support block 69 is arranged to rotate and be able to slide inside the mounting groove 68, thereby ensuring that when the threaded rod 64 is selected, the tripod 62 is pushed to rotate inside the connecting block 63 through the support block 69.

[0061] The tripod 62 is in the shape of the letter “Y”, and a mounting groove 68 is provided at the upper end of the tripod 62 . A support block 69 is provided inside the mounting groove 68 . A connecting column 67 is provided at the upper end of the support block 69 , and the connecting column 67 is rotatably installed on the lower end of the threaded rod 64 .

[0062] Among them, when the tripod 62 rotates, it will drive the friction cylinder 66 and the cylinder 65 to move, and the friction cylinder 66 and the cylinder 65 will contact the shipboard as the tripod 62 moves. Because the shipboard to be welded is arc-shaped, when the friction cylinder 66 contacts the shipboard, the cable 54 will be wound up and the friction cylinder 66 and the cylinder 65 will continue to contact the shipboard. The friction cylinder 66 and the cylinder 65 will also rotate to prevent excessive squeezing of the shipboard and cause angle differences in docking. The tripod 62 is set in the shape of the letter "Y", which can provide a larger contact area for the friction cylinder 66 and the cylinder 65, ensuring that the welded shipboard can be accurately aligned.

[0063] Among them, for curved or irregularly shaped shipboards, the friction cylinder 66 and the cylinder 65 continuously resist the surface of the shipboard, and the position of the shipboard is adjusted as the cable 54 is reeled in, so that precise alignment can be achieved even in complex shapes. By rotating the threaded rod 64, the support block 69 is pushed downward, and then the tripod 62 is rotated inside the connecting block 63 to maintain the relative angle between the shipboards and prevent angular deviation during the alignment process.

[0064] The design of friction cylinder 66 and cylinder 65 allows them to rotate when contacting the ship board, avoiding excessive extrusion due to static pressure, thereby protecting the ship board from unnecessary damage or deformation. The tripod 62 is in the shape of the letter "Y", providing a larger contact area for friction cylinder 66 and cylinder 65, ensuring uniform contact with the ship board over the entire length, and is suitable for ship boards of various shapes and sizes, increasing its application range and versatility.

[0065] Embodiment 4: Based on the locking mechanism 3 provided in Embodiment 1, this embodiment provides a further technical solution of the locking mechanism 3.

[0066] The locking mechanism 3 includes a clamping block 31, a friction plate 32 is provided on the top of the inner wall of the clamping block 31, two first round rods 34 are provided inside the clamping block 31, and half-ring blocks 35 are rotatably installed on the outer surfaces of the two first round rods 34. A support rod 33 for limiting the rotation angle of the half-ring blocks 35 is provided on the inner wall of the clamping block 31 and on one side of the first round rod 34.

[0067] The semi-ring block 35 is semicircular in shape, and a plurality of friction grooves 36 are formed on the outer surface of the semi-ring block 35 . The first round rod 34 is offset from the center of the semi-ring block 35 .

[0068] It is worth noting that when docking the shipboard, because the shipboard is made of steel plates and is easy to deform, when the edges and corners of the shipboard need to be bent and aligned, the clamp block 31 is clamped on the shipboard so that the shipboard is located between the semi-ring block 35 and the friction plate 32. When the cable 54 is wound, the movement of the casing 1 will drive the outer shell 2 and the clamp block 31 to move, and when the clamp block 31 drives the first round rod 34 to move, the friction groove 36 is provided on the surface of the semi-ring block 35 to increase the surface friction of the semi-ring block 35, and the first round rod 34 is arranged on the principle of The center of the semi-ring block 35 makes the distance between the semi-ring block 35 and the friction plate 32 gradually decrease as the semi-ring block 35 rotates, so the semi-ring block 35 rotates close to the surface of the ship plate, and as the semi-ring block 35 rotates, it will squeeze the ship plate close to the lower part of the friction plate 32, so that the ship plate is stuck between the semi-ring block 35 and the friction plate 32. When the ship plate is completely fixed between the semi-ring block 35 and the friction plate 32, the cable 54 continues to be wound up, which will pull the ship plate to deform or move, so that the two steel plates to be welded are corrected and aligned.

[0069] The shipboard is clamped between the semi-ring block 35 and the friction plate 32, and the traction force generated when the cable 54 is wound is used to drive the clamping block 31 to move, so that the semi-ring block 35 rotates closely against the surface of the shipboard and gradually squeezes the shipboard, thereby achieving precise correction and alignment.

[0070] The progressive pressure between the half ring block 35 and the friction plate 32 can effectively prevent the shipboard from being deformed unnecessarily due to excessive extrusion, while ensuring stability during the correction process.

[0071] The friction groove 36 opened on the surface of the semi-ring block 35 increases the friction between it and the ship plate, which helps to better fix the ship plate and ensure that it will not slide or shift during the correction process. As the first round rod 34 moves away from the center of the semi-ring block 35, the distance between the semi-ring block 35 and the friction plate 32 gradually decreases, and finally the ship plate is tightly fixed between the two, ensuring a good contact surface, which is beneficial to subsequent welding operations.

[0072] In this way, the corrected ship plates can be butted together more closely, reducing the possibility of cold welds, and evenly distributing welding stress, avoiding the problem of excessive local stress and improving welding quality.

[0073] The present invention also provides a method for using a steel structure welding guide alignment device for ship hull structure manufacturing, and the specific method of use is as follows:

[0074] S1. When welding the hull, steel plates need to be welded on the skeleton of the keel to shape the hull. When welding the steel plates, the welded steel plates need to be aligned tightly to ensure that the welded hull will not be poorly welded due to excessive gaps or cause other structures to be installed misaligned due to excessive gaps. Therefore, when welding, the two housings 1 need to correspond to the two ship boards that need to be welded, and then the vacuum pump inside the housing 1 extracts the gas inside the adsorption disk 8 through the ventilation pipe 7, and the adsorption disk 8 corresponds to the ship board. When the gas inside the adsorption disk 8 is extracted, it will be firmly adsorbed on the ship board;
