Abstract
Description
Technical Field
[0001] This invention relates to the field of steel structure construction technology, and in particular to a steel structure docking device for steel structure processing. Background Technology
[0002] In the butt welding of H-beams, in order to ensure that the molten pool is in a horizontal and symmetrical position during welding, and that the gravity is evenly distributed on both sides of the steel plates, thus avoiding the tendency of the molten pool to flow on one side and making it easier for the liquid metal to spread, a highly efficient ship-shaped welding method is usually used.
[0003] In the existing automated ship-shaped welding process of H-beams, a set of clamps that can maintain a certain tilt angle and a tool that can rotate the H-beam 180 degrees are usually required to make the four corners of the H-beam to be welded enter the ship-shaped position during welding. In this process, after welding two corners on the same plane, it is necessary to wait for another tool to rotate the H-beam before welding the other two corners can be carried out, which reduces the continuity of automation and thus reduces welding efficiency.
[0004] In summary, there is an urgent need for a steel structure docking device for steel structure processing that enables continuous automated ship-shaped welding at all corners during the docking process of steel structures, thereby optimizing docking efficiency. Summary of the Invention
[0005] In view of the problem of discontinuous automated welding of H-beams in existing technologies, a steel structure docking device for steel structure processing is proposed to achieve continuous automated welding of the ship-shaped shape at each corner during the docking process of steel structures, thereby optimizing the docking efficiency.
[0006] To solve the above problems, the technical solution of the present invention is as follows: A steel structure welding device for steel structure processing includes a gantry welding assembly and a workpiece clamping assembly. The workpiece clamping assembly is used to clamp the steel structure, and the gantry welding assembly is used to weld the steel structure. The workpiece clamping assembly includes a rotating shaft and a clamping assembly. The clamping assembly is mounted on the rotating shaft and can rotate 360° around the axis of the rotating shaft. The clamping assembly is used to clamp the steel structure and to make the weld seam on the steel structure parallel to the axial direction of the rotating shaft.
[0007] As a preferred technical solution, the steel structure is an H-beam, which includes a web and two flanges perpendicularly connected to both sides of the web. When the H-beam is clamped by the clamping assembly, the web is perpendicularly pointed to the axis of the rotation shaft.
[0008] As a preferred technical solution, the rotating shaft is provided with two sets of clamping assemblies, which are symmetrically arranged on both sides of the rotating shaft. Correspondingly, the gantry welding assembly is provided with two sets of welding torches.
[0009] As a preferred technical solution, the clamping assembly includes clamping drive members at both ends, and a clamping stop bar is fixedly connected between the two clamping drive members. The clamping drive members control the opening and closing of the upper and lower sets of clamping stop bars to clamp the steel structure, and the clamping stop bar is isolated between the two flange plates of the steel structure.
[0010] As a preferred technical solution, the bottom of the clamping stop is provided with a rotating roller, which can rotate freely around its own axis.
[0011] As a preferred technical solution, a lifting block is movably embedded at the bottom of the clamping stop, and a rotating roller is disposed at the bottom of the lifting block. The lifting block can move within the clamping stop. When the lifting block moves downward, the rotating roller protrudes from the lower surface of the clamping stop, and when the lifting block moves upward, the rotating roller does not protrude from the lower surface of the clamping stop.
[0012] As a preferred technical solution, the clamping stop bar is provided with a drive plate, the drive plate is perpendicular to the lifting block and located above the lifting block, the drive plate is provided with a protrusion, and the drive plate can be translated within the clamping stop bar. When the protrusion is located above the lifting block, the lifting block moves downward relative to the clamping stop bar.
[0013] As a preferred technical solution, the rotating shaft is provided with a fixed disk, which does not rotate with the rotating shaft, and the fixed disk is provided with an irregularly shaped drive track; a drive rod is connected to the drive plate, and a drive guide is provided at the end of the drive rod. The drive guide moves along the irregularly shaped drive track and pulls the drive rod and the drive plate to extend and retract.
[0014] As a preferred technical solution, the drive guide includes a telescopic connecting rod and a guide post. The telescopic connecting rod is telescopic and its two ends are respectively connected to the two drive rods. The guide post is connected in the middle, and the end of the guide post is provided with a guide ring. The guide ring is embedded in the irregular drive track and can roll in the irregular drive track.
[0015] The beneficial effects of this invention are: 1. In one rotation cycle of the rotating shaft of the steel structure docking device for structural processing described in this invention, the four welds of the steel structure appear in corresponding boat-shaped positions at the upper left, upper right, lower right, and lower left corners of the circular trajectory, respectively. Therefore, when the weld rotates to the corresponding position, the welding torch moves to the top of the corresponding weld and moves from one end of the steel structure to the other end for welding. After the first weld is completed, the rotating shaft continues to rotate, and the welding torch moves to the top of another exposed weld to weld that weld. The difference is that in the prior art, when welding the third weld, it is necessary to use a flipping mechanism to flip the steel structure and re-clamp it before welding the other two welds. In this invention, the third weld can be made to enter the boat-shaped position simply by the rotating shaft continuing to rotate in the same direction at the corresponding angle, saving the time of flipping and re-clamping, thereby improving the docking efficiency.
[0016] 2. The clamping assembly of the steel structure butt welding device for steel structure processing of the present invention clamps the web of the H-shaped steel structure through a clamping stop bar and isolates the flange plates on both sides. A lifting plate is provided inside the clamping stop bar, and a rotating roller is provided at the bottom of the lifting plate. When the steel structure is clamped using the rotating roller, the steel structure can move relative to the clamping stop bar. A fixed disk is coaxially provided on the rotating shaft, and a shaped drive track is provided on the fixed disk. A drive rod that moves along the shaped drive track is provided on the shaped drive track. One end of the drive rod is connected to the drive plate inside the clamping stop bar. When the drive rod is at different positions on the shaped drive track, it generates periodic pressure on the lifting block inside the clamping stop bar, so that the fixation between the clamping stop bar and the web plate is in a state of rigid fixation and movable fixation. The system allows for switching between two states. During operation, when the steel structure initially forms an angle with the horizontal plane, the clamping stop and the web plate are rigidly fixed, preventing relative movement. The steel structure stores its gravitational potential energy. As the steel structure rotates to a position before entering the next hull shape, the drive rod, under the change of its shaped drive track, transforms the rigid fixation between the clamping stop and the web plate into a movable fixation. At this moment, the stored gravitational potential energy is released instantaneously. The flange plate, originally far from the clamping stop, rapidly moves towards it, generating significant collision kinetic energy. This causes the bottom of the clamping stop to compress and collide with the weld slag on the weld seam that has already been welded, thus removing the weld slag.
[0017] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation
[0019] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] To better understand the steel structure docking device for steel structure processing provided in this embodiment, a brief introduction to the existing automated ship-shaped welding steel structure docking device is given below. The existing automated ship-shaped welding steel structure docking process includes: Automated assembly line: On this production line, three steel plates are automatically spliced together to form an H-beam, and then initially fixed by spot welding.
[0021] Automated welding production line: On this production line, the assembled H-beams need to be transferred to the ship-shaped welding platform first. The H-beams clamped on the welding platform can rotate left and right with the welding platform. By rotating, the H-beams are brought into a 45° ship-shaped position. The welding torch is set up directly above the welding platform via a gantry frame. During welding, the welding torch is aimed at the angle to be welded on the H-beams. The H-beams are welded by moving the gantry frame. After one weld is completed, the welding platform rotates in the other direction, and the welding torch moves to the other side of the weld for welding. After welding is completed, a special flipping mechanism is needed to flip the H-beams 180 degrees before the welding platform can rotate again to perform ship-shaped welding on the other side of the weld angle.
[0022] To address the problem in the prior art where, during welding of the same H-beam, another flipping tool is needed to flip the H-beam before welding the next side, the present invention provides a steel structure welding device for steel structure processing: The steel structure docking device for steel structure processing includes a gantry welding assembly and a workpiece clamping assembly. The gantry welding assembly includes a moving guide rail 1, a gantry frame 2, a welding torch 3, and a corresponding control mechanism. In this embodiment, two sets of moving guide rails 1 are symmetrically arranged on both sides of the workpiece clamping assembly. The gantry frame 2 spans the workpiece clamping assembly and is mounted on the moving guide rail 1, and can move along the moving guide rail 1. The welding torch 3 is mounted on the crossbeam of the gantry frame 2. Preferably, the welding torch 3 can move left and right on the crossbeam and can move up and down. It should be understood that the gantry welding assembly is prior art.
[0023] To integrate the tilting clamping and flipping processes in existing steel structure welding devices and improve welding efficiency, please refer to the appendix. Figure 1 , Figure 1This is a three-dimensional schematic diagram of the steel structure docking device for steel structure processing according to the present invention. In the present invention, the workpiece clamping assembly includes a rotating shaft 4 and a clamping assembly 5. The rotating shaft 4 is used to drive the clamping assembly 5 to rotate 360°. Specifically, the two ends of the rotating shaft 4 are supported by support seats 41. One end of the rotating shaft 4 is engaged with the drive assembly 42 through a transmission method such as gears. The drive assembly 42 can be a drive mechanism such as a motor that drives the rotating shaft 4 to rotate around its own axis. The clamping assembly 5 for clamping the steel structure 6 is provided on the rotating shaft 4. The steel structure 6 clamped on the clamping assembly 5 is parallel to the axis of the rotating shaft 4. Specifically, the clamping assembly 5 is composed of a plurality of jaws arranged along the axial direction of the rotating shaft 4.
[0024] During the welding process of the steel structure butt welding device for structural processing described in this invention, the assembled steel structure 6, i.e., the H-beam, is transferred to the clamping assembly 5. To ensure that the weld seam of the H-beam is fully exposed below the welding torch 3, please refer to the appendix. Figure 2 , Figure 2 The diagram shows the various ship-shaped welding positions of the steel structure docking device for steel structure processing according to the present invention. In this embodiment, the jaws on the clamping assembly 5 are clamped on the flange plate 61 of the H-beam, and its web plate 62 is perpendicular to the axis of the rotating shaft 4, so that the four welds can smoothly enter the ship-shaped position in sequence during the rotation of the rotating shaft 4. Specifically, during one rotation cycle of the rotating shaft 4, the four welds of the steel structure 6 appear in corresponding boat-shaped positions at the upper left, upper right, lower right, and lower left corners of the circular trajectory. When the welds rotate to the corresponding positions, the welding torch 3 moves to directly above the corresponding weld and moves from one end of the steel structure 6 to the other for welding. After the first weld is completed, the rotating shaft 4 continues to rotate, and the welding torch 3 moves to directly above another exposed weld to weld that weld. The difference is that in the prior art, when welding the third weld, it is necessary to use a flipping mechanism to flip the steel structure 6 and re-clamp it before welding the other two welds. However, in this invention, the third weld can be made to enter the boat-shaped position simply by the rotating shaft 4 continuing to rotate in the same direction at the corresponding angle, saving the time of flipping and re-clamping, thereby improving the docking efficiency.
[0025] To further improve the efficiency of the steel structure connection, please refer to the appendix. Figure 3 , Figure 3This is a three-dimensional schematic diagram of a steel structure docking device for processing steel structures with two processing stations. In some preferred embodiments, the rotating shaft 4 is provided with two sets of clamping assemblies 5, which are symmetrically arranged on both sides of the rotating shaft 4, i.e., centrally symmetrical with respect to the central axis of the rotating shaft 4. During use, the rotating shaft 4 simultaneously clamps and fixes two sets of steel structures 6 through the two sets of clamping assemblies 5. Correspondingly, the gantry welding assembly is provided with two sets of welding torches 3. During use, the two welding torches 3 can simultaneously weld two steel structures 6 located diagonally. Specifically, when one weld of one steel structure 6... When the steel structure is positioned in the upper left boat-shaped position, the welding torch 3 located on the left side of the crossbeam of the gantry 2 welds it. At the same time, one of the welds of the other steel structure 6 is located in the lower right boat-shaped position, and the welding torch 3 located on the right side of the crossbeam of the gantry 2 welds it simultaneously. After welding is completed, when moving to the next welding position, taking clockwise rotation as an example, the first steel structure 6 moves to the upper right corner and is welded by the welding torch 3 on the right, while the other moves to the lower left corner and is welded by the welding torch 3 on the left. In this embodiment, the docking work of two steel structures 6 is completed simultaneously within one rotation cycle of the rotating shaft 4, which multiplies the production efficiency.
[0026] During the butt welding process of steel structure 6, weld slag and other residues are generated. As the rotating shaft 4 rotates, these residues are transferred along with the inclined web 62 to adjacent weld seams, causing welding defects. This is especially problematic in submerged arc welding, where not only weld slag but also flux residues remain. In existing technology, manual cleaning is required before proceeding to the next weld. To address these issues and prevent residues from the previous weld from affecting the next weld, please refer to the appendix. Figure 4 Appendix Figure 5 , Figure 4 This is a perspective view of the steel structure docking device for processing the steel structure, which includes another clamping assembly. Figure 5 for Figure 4A partially enlarged schematic diagram of section A shows that, in this embodiment, the clamping assembly 5 consists of clamping drive members 51 at both ends and clamping stop bars 52 connecting the two clamping drive members 51. The clamping stop bars 52 have two sections, upper and lower, which are driven to open and close by the clamping drive members 51 on both sides. During use, the upper and lower clamping stop bars 52 clamp and fix the web plate 62 of the H-beam. The clamping stop bars 52 are isolated between the two flange plates 61. After the weld between one flange plate 61 and the web plate 62 is completed, when moving to the next ship position, such as from the upper left corner to the upper right corner, although the residue in the weld is still moving towards the adjacent weld, it is blocked by the clamping stop bars 52 in the middle of the web plate 62, thereby preventing the residue from entering the weld to be welded. This solves the problem of mutual interference of weld slag without affecting the welding efficiency.
[0027] In the steel structure docking device for steel structure processing described in this invention, a preferred embodiment is also provided, please refer to the appendix. Figure 6 Appendix Figure 7 , Figure 6 This is a schematic diagram showing the changing states of the steel structure docking device used for processing the steel structure, which includes a rotating roller. Figure 7 for Figure 6 A magnified view of part of D. Figure 6 The dashed line indicates the position of the steel structure 5 before sliding. Specifically, the bottom of the clamping stop 52 is provided with a rotating roller 53, which can rotate freely around its own axis. During clamping, the rotating rollers 53 on the upper and lower clamping stops 52 contact the upper and lower surfaces of the web 62 respectively, providing a clamping force perpendicular to the web 62. Due to its own rolling characteristics, during the rotation of the rotating shaft 4, the web 62 and the clamping stop 52 can slide relative to each other due to the weight of the steel structure 6. Specifically, during its use, if the steel structure 6 is located in the upper left corner, sliding the steel structure 6 to the lower right will not affect the angle of the corresponding weld entering the corresponding boat-shaped position. Since the clamping stop 52 has been moved to the other side away from the weld at this time, it provides sufficient space for welding compared to when it is clamped in the middle position of the web 62. The same applies to other positions such as below, which will not be elaborated here.
[0028] The steel structure butt welding device for steel structure processing described in this invention not only simplifies the automated welding process of steel structure 6, but also actively cleans weld slag and other residues after welding; please refer to the appendix. Figure 8 Appendix Figure 9 Appendix Figure 10 , Figure 8 This is a schematic diagram of a steel structure docking device for steel structure processing, which allows for timely switching between movable and fixed clamping. Figure 9 for Figure 8A magnified view of part B in the diagram. Figure 10 for Figure 9 The enlarged schematic diagram of part C and the schematic diagram before and after the state switch are shown. Specifically, a lifting groove 521 perpendicular to its lower surface is provided in the clamping stop bar 52, and a translation groove 522 is provided above the lifting groove 521. A lifting block 54 that can move up and down along the lifting groove 521 is provided in the lifting groove 521. Limiting blocks are provided on both sides of the lifting block 54, which cooperate with the limiting groove on the side wall of the lifting groove 521 to prevent the lifting block 54 from completely disengaging from the clamping stop bar 52. A driving plate 55 is provided in the translation groove 522 above the lifting block 54. The driving plate 55 can move horizontally in the translation groove 522. A protrusion 551 is provided below the driving plate 55. Slopes are provided on both sides of the top of the lifting block 54 to facilitate the protrusion 551 to enter the top of the lifting block 54. To achieve timely driving of the lifting block 54, drive rods 552 are connected to both sides of the drive plate 55. The drive rods 552 extend to the vicinity of the rotation axis 4 at an angle perpendicular to the rotation axis 4. The drive rods 552 on the upper and lower drive plates 55 are also symmetrically arranged vertically, and their ends are connected by a combined telescopic connecting rod 71 on the drive guide 7. The combined telescopic connecting rod 71 is vertically connected to the drive rods 552 at both ends. When the clamping stop 52 opens and closes vertically, the combined telescopic connecting rod 71 extends and retracts accordingly, thus not affecting the guide post 72 connected to the middle of the combined telescopic connecting rod 71. (See attached diagram for details.) Figure 11 , Figure 12 , Figure 11 This is a partial schematic diagram of a steel structure docking device for steel structure processing, which allows for timely switching between movable and fixed clamping. Figure 12This is a partial cross-sectional view of the fixed disc described in this invention. In this embodiment, a fixed disc 8 is provided on the support base 41 used to support the rotating shaft 4. The fixed disc 8 is provided with a non-circular drive track 81, which is composed of two arc tracks of different diameters, one large and one small, smoothly intersecting and connecting. A guide ring 73 is provided on the guide post 72, and the guide ring 73 is embedded in the non-circular drive track 81. When the rotating shaft 4 rotates, the guide ring 73 also moves around the rotating shaft 4 along the non-circular drive track 81. Preferably, in the non-circular drive track 81, whenever it is located at the upper left corner, upper right corner, ... When the lower left and lower right corners are in such areas, the diameter of the track becomes smaller. When the drive guide 7 moves from the large track to the small track, it pulls the drive rod 552 to move toward the axis of the rotating shaft 4, thereby pulling the drive plate 55 to move in the translation groove 522. During the movement, the protrusion 551 below the drive plate 55 gradually enters the top of the lifting block 54, causing the lifting block 54 to be pressed and move along the lifting groove 521 toward the web plate 62. Finally, the rotating roller 53 below the lifting block 54 contacts the web plate 62, and the lower surface of the clamping stop 52 disengages from the web plate 62, so that the steel structure 6 can move relative to the clamping stop 52 again.
[0029] It should be noted that: the clamping stop 52 of the steel structure docking device for steel structure processing of the present invention is provided with a lifting plate, and the bottom of the lifting plate is provided with a rotating roller 53. When the steel structure 6 is clamped by the rotating roller 53, the steel structure 6 can move relative to the clamping stop 52. Furthermore, a fixed disk 8 is provided coaxially with the rotating shaft 4. The fixed disk 8 is provided with a special-shaped drive track 81. The special-shaped drive track 81 is provided with a drive rod 552 that moves along it. One end of the drive rod 552 is connected to the drive plate 55 inside the clamping stop 52. When the drive rod 552 is in different positions on the special-shaped drive track 81, it generates periodic pressure on the lifting block 54 inside the clamping stop 52, so that the fixation between the clamping stop 52 and the web plate 62 is in a state of switching between rigid fixation and movable fixation. Its advantage is that when the steel structure 6 initially forms an angle with the horizontal plane... At this time, since the clamping stop 52 and the web plate 62 are in a rigid fixed state, they cannot move relative to each other. The gravitational potential energy of the steel structure 6 is stored. When the steel structure 6 rotates to a certain position before entering the next hull position, the drive rod 552 simultaneously changes the rigid fixedness between the clamping stop 52 and the web plate 62 under the change of the trajectory of the irregular drive track 81. At this time, the gravitational potential energy stored in the steel structure 6 itself is released instantly. At this time, the flange plate 61, which was originally far away from the clamping stop 52, quickly moves towards the clamping stop 52, thereby generating a large collision kinetic energy. This causes the bottom of the clamping stop 52 to squeeze and collide with the weld slag of the weld that has been welded on this side, thereby completing the removal of the weld slag. Preferably, in some embodiments, a protruding mechanism with a tapered cross section can be provided on the base side wall of the clamping stop 52, so that it has a better removal effect when impacted.
[0030] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and additions without departing from the principle of the present invention, and these improvements and additions should also be considered within the scope of protection of the present invention.
