Description

Technical Field

[0001] This invention relates to an extended horse board with built-in orthopedic function and its method of use, which belongs to the field of shipbuilding technology. Background Technology

[0002] In the shipbuilding industry, plate splicing is the most basic and common process in hull production. Depending on the thickness, shape, size of the plates and the working conditions (flat splicing, vertical splicing, etc.), operators must choose different working methods and tools.

[0003] In shipbuilding, plate splicing primarily utilizes prefabricated supports (also called positioning supports or saddles) cut from steel plates (selected from plates of the same material as those to be spliced, as welding dissimilar materials can easily lead to intergranular corrosion or hot cracking) for fixed welding. Examples include the "positioning support" disclosed in document CN 202726333 U for welding thick-walled steel cylinders, and the "butt welding method for thick-walled steel cylinders" disclosed in document CN102728985 B. Positioning supports are commonly used tools in welding ship plates or large steel plates, serving as crucial fixtures for temporarily fixing weldments, ensuring assembly accuracy, and controlling welding deformation. During use, the support needs to be welded to the plate being welded, relying on the strong constraint generated by the welded connection to achieve positioning and assembly. Then, the weld is performed, ensuring a smooth weld and ease of construction. After welding, the support needs to be removed, and the ship plate surface must be ground.

[0004] The production of residential areas is an important part of the shipbuilding process. The plate jointing process requires high precision and is complex to control. In particular, the vertical bulkheads generally use thin plates (t ≤ 12mm). When the plate joints are spliced ​​and leveled, a variety of tools such as iron support plates, back beams, hydraulic jacks, and aluminum tie rod hoists are required to work together.

[0005] First, the support plate and back beam are fixed to the two thin plates to be spliced ​​using tack welding. The two plates are then joined together. Because traditional support plates lack straightening capabilities, the joints between the plates are uneven. Even with the back beam, they cannot be leveled automatically. Hydraulic jacks and aluminum lever hoists are needed to straighten the joints. This process requires at least two people working together. To ensure… accuracy This process requires the use of numerous steel plates for connection, followed by assembly and welding. After construction is complete, all steel plates and back beams are removed, and the remaining steel plate remnants are treated, then ground, repaired, and ground again, resulting in damage to the base steel plate. This type of plate splicing operation is cumbersome. The thin plates are extremely prone to heat deformation during the operation, requiring a large amount of corrective and auxiliary work, necessitating multiple people to work together, and is time-consuming. After the back beams are hot-cut, they are heated, and the heated surfaces deform to varying degrees, rendering them unusable and resulting in waste of auxiliary materials. Summary of the Invention

[0006] To address the problems in existing technologies regarding the welding and splicing of thin steel plates, such as cumbersome plate joint leveling operations, the need for thermal cutting to remove a large amount of steel plates after welding, the heat deformation of thin steel plates, damage to the base material, and the inability to reuse auxiliary materials such as steel plates and back beams due to thermal cutting deformation.

[0007] This invention provides an extended steel plate with a built-in straightening function and its method of use. Using this device and method, the steel plate can be straightened while the steel plate is positioned, thus improving production efficiency while ensuring assembly accuracy.

[0008] The technical solution adopted in this invention is: an extended board with a self-correcting function, including a long strip back beam that spans across two thin steel plates to be welded and is perpendicular to the thin steel plates to be welded, and the back beam is orthogonal to the plate seam between the two thin steel plates; One side of the back beam is the working side, which has weld holes; the other side of the back beam is the fixed side. The back beam at the fixed side is fixedly connected to the fixing strip through the connecting block to form a stud slide. The adjusting stud is vertically set in the stud slide. The adjusting stud has a welding end at one end on the working side, which is used for perpendicular welding to the back of the thin steel plate; the other end, which extends out of the stud slide, is the fixing end, and a nut is installed on the fixing end. The adjusting stud moves along the stud slide in the length direction of the back beam to adjust the relative position of the plate seam and the weld hole; the adjusting stud moves the welding end in the width direction of the back beam by rotating the nut to adjust the distance between the back side of the thin steel plate to be welded and the working edge.

[0009] Furthermore, the edges of the weld holes are blunted.

[0010] Furthermore, multiple connecting blocks are installed between the back beam and the fixing strip at the fixed edge, dividing the stud slide into multiple sections, with at least one set of adjusting studs and nuts installed in each section of the stud slide.

[0011] Furthermore, the width of the stud slide is greater than the diameter of the adjusting stud but less than the diameter of the nut.

[0012] Furthermore, the weld holes are staggered from the connecting blocks.

[0013] The method for welding and splicing thin steel plates using an extended steel plate with built-in straightening function includes the following steps: S1. Clean the butt joint edges of the thin steel plates to be welded; S2. Place the entire device across the middle of the two thin steel plates that are joined together, align the welding holes with the plate seam, and make the back beam perpendicular to the thin steel plate to be welded and orthogonal to the plate seam. Make the working edge with the welding holes contact the thin steel plate. S3. The welding end of the adjusting stud is welded to the thin steel plate to be welded, and the adjusting stud is perpendicular to the thin steel plate to be welded; S4. Tighten the adjusting stud at the fixed end of the back beam using the nut. The welding end will drive the thin steel plate to be welded, which is welded to it, to move closer to the working edge until the working edge is completely pressed onto the thin steel plate to be welded, thus completing the plate seam splicing and leveling. S5. After installing several extended masts with self-correcting function according to the length of the plate joint, perform thin steel plate welding and assembly. S6. After the entire weld is completed and cooled, loosen the bolts, use an arc to cut the weld foot of the adjusting stud, and remove the back beam.

[0014] Furthermore, in step S2, when there are components on the reverse side of the thin steel plate to be welded, the position of the reverse structural component is marked, and the back beam is aligned with the reverse component.

[0015] Furthermore, in step S4, a torque wrench is used to precisely control the clamping force.

[0016] Compared with the prior art, the present invention has the following advantages: (1) Reduce labor intensity: With the help of this device, a single person can complete the assembly of the wall panels in the residential area, avoiding the use of other tools and reducing physical labor; (2) Avoid damage to the steel plate base material: replace the positioning welding, hot cutting of the steel plate and the back beam steel plate with bolt adjustment to reduce or even avoid damage to the steel plate base material and avoid subsequent steel plate repair work. (3) Prevent wall panel deformation: During the operation of using this fixture, the wall panels of the residential area can be connected by spot welding. The steel plate will not be thermally deformed, and the subsequent plate leveling operation can be carried out. (4) Reduce the consumption of auxiliary materials for the hull: The jigs for positioning the auxiliary thin plate splicing are studs, and the main back beam can be reused, which solves the problem of the original auxiliary materials being consumed after a single use and reduces the cost of hull auxiliary materials during the ship construction process.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. 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.

[0023] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0024] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0025] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

It should be understood that spatial relative terms are intended to encompass different orientations in use or operation besides the orientation of the device as described in the figures. For example, if the device in the figures is inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0027] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0028] Based on the operational scenario of thin plate jointing, a special extended support plate with self-correcting function is designed to assist in the positioning of thin plate splicing. It replaces various tools such as iron support plates, back beams, hydraulic jacks, and aluminum tie rod hoists. By using the structural components on the wall panel to bear the force, the joint of the wall panel is corrected by adjusting the bolts.

[0029] The extended support plate with built-in orthopedic function includes a long strip-shaped back beam that spans across the two thin steel plates to be welded together, is perpendicular to the thin steel plates to be welded, and is orthogonal to the plate seam. The working edge of the back beam is close to the thin steel plate and has the same shape as the thin steel plate, with weld holes opened; The fixed edge of the back beam is away from the thin steel plate, and a fixing strip is installed by fixing blocks that are staggered from the welding holes. A stud slide is formed between the fixing strip and the back beam. The welding end of the adjusting stud passes through the stud slide, and the fixed end protrudes outside the fixed edge. A nut is fitted on it. The adjusting stud can slide inside the stud slide. The material of the adjusting stud is compatible with the thin steel plate to be welded. The fixed edge of the fixing strip has the same outline as the fixed edge.

[0030] Furthermore, the edges of the weld holes are blunted.

[0031] And a method for welding and splicing thin steel plates using the extended steel plate with built-in orthopedic function as described in claim 1: S1. Clean the butt joint edges of the thin steel plates to be welded; S2. Place the entire device across the middle of the two thin steel plates that are joined together, align the welding hole with the plate seam, and make the back beam perpendicular to the thin steel plate to be welded and orthogonal to the plate seam. The long side of the side with the welding hole should be in contact with the thin steel plate. S3. The welding end of the adjusting stud is welded to the thin steel plate to be welded. The adjusting stud is perpendicular to the thin steel plate to be welded and is welded only on the side away from the back beam to avoid interference between the back beam and the weld foot. S4. Tighten the adjusting stud at the fixed end of the back beam with the nut, press the fixed edge with the nut, press the working edge with the thin steel plate to be welded, and make the working edge of the back beam fully contact the steel plate to complete the splicing and leveling of the plate seam. S5. After installing several extended masts with self-correcting function according to the length of the plate joint, perform thin steel plate welding and assembly. S6. After the entire weld is completed and cooled, loosen the bolts, use an arc to cut the weld foot of the adjusting stud, and remove the back beam.

[0032] Furthermore, in S2, when there are components on the reverse side of the thin steel plate to be welded, mark the position of the reverse structural component and align the back beam with the reverse component.

[0033] Furthermore, S4, use a torque wrench to precisely control the clamping force.

[0034] This extended support board with built-in orthopedic function mainly includes the following parts: Back Beam 1: The main load-bearing and straightening reference component for auxiliary thin plate splicing and positioning.

[0035] It is long and narrow, with a welding hole 7 on one long side. The size and shape of the welding hole 7 are processed according to the needs of on-site construction to ensure that the welding is unobstructed; the edge of the hole is blunted to prevent scratching the thin steel plate 8.

[0036] The size is typically not less than that of a semicircle with a radius of 25 mm.

[0037] Preferably, when the back plate is rectangular, its dimensions are 1000 mm in length and 150 mm in width; the material does not necessarily have to be compatible with the thin steel plate 8 to be welded. When lightweight requirements are needed (such as ship superstructures and container skins), aluminum alloy can be selected to save manpower; when high strength requirements are needed (such as tank wall panels and steel structure roof panels), carbon steel can be selected.

[0038] When using it, first clean the butt joint edge of the thin plate to be welded (remove rust and oil stains to expose the metal luster). The back beam 1 spans between the two thin steel plates 8 to be welded. The back beam 1 is perpendicular to the thin steel plate 8 to be welded and orthogonal to the plate seam 9. The long side with the weld hole 7 is in complete contact with the thin steel plate 8 and serves as the working side 11.

[0039] Preferably, when there are components on the reverse side of the thin steel plate 8 to be welded, the position of the reverse structural component is marked, and the back beam 1 is aligned with the reverse component. This makes full use of the reverse component structure to form a positive and negative alignment structure, which is more conducive to straightening the plate joint and preventing deformation.

[0040] The shape of the working edge 11 is processed according to the needs of the thin steel plate 8 to be welded. For the same thickness butt joint, a flat working edge 11 is used, and for the unequal thickness butt joint, a stepped working edge 11 can be used. For example, when splicing different thicknesses, there is a height difference on both sides of the plate seam 9, so the extension length of the working edge 11 on both sides of the plate seam 9 can be adjusted.

[0041] Fixing strip 2: Located on the long side opposite the working side 11 (referred to as fixing side 12), it is fixed to the back beam 1 by connecting block 3. A stud slide 4 is formed between the back beam 1 and the fixing strip 2. The thickness of the connecting block 3 is the same as that of the stud used, ensuring that the stud can slide in the stud slide 4 without being excessively loose (the stud slides smoothly without radial wobble). The shape of the fixing strip 2 on the side of fixing side 12 coincides with the shape of the side of fixing side 12 of the back beam 1. The number of fixing blocks is determined according to the length of the mounting plate and the required number of bolts, and they are staggered from the through-weld holes 7.

[0042] Adjusting stud 5: The material of adjusting stud 5 must be compatible with the thin steel plate 8 to be welded to avoid intergranular corrosion or hot cracking caused by welding dissimilar materials. Adjusting stud 5 passes through stud slide 4 and can slide within stud slide 4.

[0043] In use, the welding end 13 of the adjusting stud 5 is welded to the thin steel plate 8 to be welded. The adjusting stud 5 is perpendicular to the thin steel plate 8 to be welded, and welding is only performed on the side away from the back beam 1. Single-sided welding makes disassembly easier, reduces heat input, and avoids interference between the welding foot 10 and the back beam 1.

[0044] Adjusting stud 5 extends from the fixed end 14 of the back beam 1 and tightens it with nut 6. Nut 6 presses against the fixed edge 12, pressing the working edge 11 against the thin steel plate 8 to be welded. The working edge 11 of the back beam 1 is in complete contact with the steel plate, making the shape of the two butt-jointed steel plates the same as that of the working edge 11, thus completing the splicing and leveling of the plate seam 9. Furthermore, it provides strong support during the welding process of the plate seam 9, ensuring the flatness of the weld.

[0045] Preferably, using a torque wrench allows for precise control of the tightening force, avoiding situations such as "over-tightening and damaging the thin plate" or "over-loosening and positioning failure" that may occur when manually tightening the nut 6, thus ensuring the straightening accuracy.

[0046] The welding position of the adjusting stud 5 should preferably be aligned with the part of the internal structural component. This can better generate strong restraint to complete the splicing and leveling of the plate seam 9, and can effectively prevent the thin steel plate 8 from deforming during assembly and welding.

[0047] Based on the length of the seam 9, install several extended support plates with built-in straightening function to complete the welding and assembly of the thin steel plate 8. After the entire weld is completed, loosen the bolts, cut the weld leg 10, remove the extended support plate with built-in straightening function, and reuse it.

[0048] Preferably, removing the weld after it has cooled down can avoid the thin plate springback deformation caused by disassembly.

[0049] When cutting weld joints, the arc should be struck on the adjusting stud 5 to avoid creating pitting on the thin steel plate 8 of the hull. Since only one side is welded when the adjusting stud 5 is initially welded to the thin steel plate 8, the cutting operation is short and generates little heat. Furthermore, most weld joints are located on the back of the thin steel plate 8 where there are components or structural parts, thus the thin steel plate 8 is less prone to deformation. The main back beam 1 has been removed, and the process of cutting the weld leg 10 will not affect the main back beam 1. The main back beam 1 can be reused; the consumed auxiliary material has changed from the support plate to the stud. The stud has a certain length allowance and can therefore also be reused.

[0050] This extended support plate with built-in straightening function can fix the butt-jointed thin steel plates 8, determine the relative positions of the butt-jointed steel plates, and ensure that the plate seams 9 are aligned and flat. During the welding and assembly process of the steel plate butt joints, it can provide strong support and ensure the flatness of the weld position. It can be operated by one person. Large auxiliary materials (back beam 1) can be reused with zero loss, with only a small amount of adjustment studs 5 being wasted. However, since the studs have a margin of length, they can also be reused, improving efficiency and saving labor and material costs.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
