Description

Technical Field

[0001] The present invention relates to the technical field of sound barrier steel structure welding, and in particular to double-station sound barrier steel structure welding equipment and a process. Background Art

[0002] Sound barriers are one of the most effective solutions for addressing noise issues along high-speed railway lines. Their primary function is to reduce the impact of railway noise on the surrounding area. In addition to being subjected to the forces of gravity and random natural crosswind loads, sound barriers are also subject to the repeated effects of pulsating pressure generated by passing trains. At high train speeds, especially high-speed trains reaching speeds of up to 350 km / h, these pulsating pressures can have a significant impact on sound barriers, in some cases even damaging barrier components and endangering traffic safety.

[0003] The current sound barrier steel structure is usually an H-shaped steel structure. During the processing, it is transported to the welding end by a handling robot and then welded by a welding robot. When the weld on one side is completed, it needs to be turned over by a flipping device. However, after turning over, the H-shaped steel structure is difficult to maintain its original position, so the welding robot needs to reposition the weld, which is not only prone to errors but also affects the welding efficiency.

[0020] A double-station sound barrier steel structure welding process, applied to the above-mentioned double-station sound barrier steel structure welding equipment, includes the following steps:

[0021] The sound barrier steel structure is transported to the second U-groove by the transport robot, and the sound barrier steel structure is positioned by the positioning part;

[0022] After positioning is completed, the welding robot performs welding on the weld seam;

[0023] After the welding of one side is completed, the rotating part drives the positioning plate to rotate to turn the sound barrier steel structure 180 degrees and weld the weld on the next side;

[0024] After welding is completed, the component is removed by the handling robot 1 .

[0025] Beneficial effects of the present invention:

[0026] (1) In the present invention, when the first welding station is in the process of welding the sound barrier steel structure, the next set of sound barrier steel structures to be welded can be loaded to the second welding station. Therefore, when the welding of the sound barrier steel structure at the first welding station is completed, the welding robot can directly weld the sound barrier steel structure at the second welding station, saving the loading time. Accordingly, the sound barrier steel structure at the first welding station is unloaded and loaded, further improving the welding efficiency.

[0027] (2) After the sound barrier steel structure in the present invention is positioned on the positioning plate, the weld seam on it is welded by a welding robot. After the welding of the weld seam on this surface is completed, this embodiment drives the positioning plate to rotate by the rotating part to flip the sound barrier steel structure 180 degrees, and then the weld seam on the lower side can be welded. After the sound barrier steel structure is positioned in the first U groove and the second U groove, the present invention does not need to use a crane to turn the sound barrier steel structure over. It can be automatically turned over by the rotating part, which not only improves the turning efficiency, but also after the turning is completed, the sound barrier steel structure is always positioned in the first U groove and the second U groove to avoid the phenomenon that the sound barrier steel structure is misaligned with the initial position when the crane is used to turn it over. When the welding robot welds the other side, it does not need to be positioned again, which can further improve the welding efficiency and ensure the uniformity of the weld seams on the upper and lower sides of the sound barrier steel structure.

[0028] (3) Before welding, the present invention first transports the two side wing plates to the second U groove, and pre-positions the two side wing plates through the first positioning mechanism, and then transports the web plate between the two side wing plates and makes it horizontal, and then drives the two side wing plates toward each other and fits with the web plate through the first positioning mechanism, thereby realizing the re-positioning of the wing plates. After the wing plates are positioned, the height of the web plate between the two side wing plates is adjusted by the second positioning mechanism, so that the contact surface between the web plate and the wing plates is located in the middle position of the wing plates. Before welding the sound barrier steel structure, the present invention does not require manual pre-spot welding. The two groups of wing plates to be welded and one group of web plates can be directly positioned in the second U groove through the positioning mechanism. In the positioning process, it can be ensured that the web plate is located in the center position between the two side wing plates to improve the welding accuracy.

[0029] (4) In the present invention, since the center of gravity axis of the web is coaxial with the central axis of the positioning plate, when the rotating part drives the positioning plate to rotate, the center of gravity axis of the web and the central axis of the positioning plate can also always remain coaxial. When the web rotates 180 degrees, its position coincides with the initial position. As a result, after the weld seam on one side of the sound barrier steel structure is welded, as it rotates 180 degrees, the positions of the weld seams on the two side surfaces are replaced, and the weld position will not change. Therefore, there is no need for the welding robot to re-identify and locate the weld seam, and welding can be carried out directly, thereby improving welding efficiency and stability.

DETAILED DESCRIPTION

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making any creative efforts shall fall within the scope of protection of the present invention.

[0042] Example 1

[0043] See also Figure 1-Figure 3 As shown, the present invention is a double-station sound barrier steel structure welding device, comprising a handling robot 1, with a first welding station 2 and a second welding station 201 for welding the sound barrier steel structure 4 symmetrically arranged on both sides of the handling robot 1;

[0044] In this embodiment, the transport robot 1 may be a DEPRAGDPS series robot, and this embodiment does not limit its specific model;

[0045] Among them, welding robots 104 are respectively arranged on one side of the first welding station 2 and the second welding station 201;

[0046] Specifically, the welding robot 104 of this embodiment can adopt the HANMOR AI intelligent welding robot or the Saibang intelligent DCVR-B921 steel structure H-beam welding robot. This embodiment does not limit its specific model as long as it can meet actual welding needs.

[0047] It should be noted that, in this embodiment, two groups of welding stations are set up. First, the workpiece to be welded is transported to the welding station by the transport robot 1, and the workpiece is welded by the welding robot 104 on one side of the welding station. By setting up two groups of welding stations, while one group of welding stations is welding, the other group of welding stations can be loaded and unloaded by the transport robot 1, thereby improving the welding efficiency. For example: when the first welding station 2 is welding the sound barrier steel structure 4, the next group of sound barrier steel structures 4 to be welded can be loaded and unloaded to the second welding station 201. Therefore, when the sound barrier steel structure 4 of the first welding station 2 is welded, the welding robot 104 can directly weld the sound barrier steel structure 4 of the second welding station 201, saving the loading time. Accordingly, the sound barrier steel structure 4 of the first welding station 2 is unloaded and loaded, further improving the welding efficiency.

[0048] In this embodiment, the first welding station 2 and the second welding station 201 both include two sets of positioning modules 3 for positioning the sound barrier steel structure 4; specifically, before welding, the sound barrier steel structure 4 is positioned by the two sets of positioning modules 3 to improve the stability of the subsequent welding process.

[0049] See also Figure 2 The positioning module 3 includes a positioning seat 301, a positioning ring 302 is fixedly arranged in the positioning seat 301, a first U-groove 304 for positioning the sound barrier steel structure 4 is provided on the positioning ring 302, a positioning plate 303 is rotatably arranged in the positioning ring 302, and a second U-groove 305 for positioning the sound barrier steel structure 4 is provided on the positioning plate 303, and the size of the first U-groove 304 and the second U-groove 305 are equal; specifically, in this embodiment, the groove width of the first U-groove 304 and the second U-groove 305 is greater than the width of the sound barrier steel structure 4, so as to facilitate the loading and unloading of the sound barrier steel structure 4.

[0050] The positioning plate 303 is provided with a positioning portion for positioning the sound barrier steel structure 4 in the second U-groove 305. Specifically, after the sound barrier steel structure 4 is transported to the second U-groove 305 by the transport robot 1, the sound barrier steel structure 4 is positioned by the positioning portion.

[0051] Among them, a rotating part is provided on the positioning seat 301, and the rotating part is used to drive the positioning plate 303 to rotate; specifically, after the sound barrier steel structure 4 is positioned on the positioning plate 303, the welding robot 104 is used to weld the welds on it. After the welding of the welds on this surface is completed, this embodiment drives the positioning plate 303 to rotate by the rotating part to flip the sound barrier steel structure 4 180 degrees, and then the welds on the next side can be welded. After the sound barrier steel structure 4 is positioned in the first U-groove 304 and the second U-groove 305 in this embodiment, there is no need to use a crane equipment to turn the sound barrier steel structure 4 over. It can be automatically turned over by the rotating part, which not only improves the turning efficiency, but also after the turning is completed, the sound barrier steel structure 4 is always positioned in the first U-groove 304 and the second U-groove 305 to avoid the phenomenon that the sound barrier steel structure 4 is misaligned with the initial position when the crane is used to turn it over. When the welding robot 104 welds the other side, there is no need to re-position it, which can further improve the welding efficiency and ensure the uniformity of the welds on the upper and lower sides of the sound barrier steel structure 4.

[0052] Example 2

[0053] Based on Example 1, please refer to Figure 1 The sound barrier steel structure 4 includes two groups of parallel and symmetrical wing plates 402, the wing plates 402 are vertically arranged, and a web 401 is provided between the two groups of wing plates 402. The web 401 is horizontally arranged, and two welds are formed on the upper and lower sides of the contact surface between the two ends of the web 401 and the wing plates 402 respectively; it can be explained that the contact surface between the web 401 and the wing plates 402 of this embodiment is located in the middle position of the wing plates 402 to ensure the uniformity of the strength of the sound barrier steel structure 4 after forming. Accordingly, the welding robot 104 of this embodiment needs to weld both welds on the upper and lower sides during welding to further improve the strength of the connection between the web 401 and the wing plates 402.

[0054] In order to further improve the welding efficiency, in this embodiment, the positioning portion includes a first positioning mechanism arranged on one side of the second U-groove 305 for positioning the two side wing plates 402, and also includes a second positioning mechanism for positioning the web 401. Specifically, in this embodiment, before welding, the two side wing plates 402 are first transported to the second U-groove 305, and the two side wing plates 402 are pre-positioned by the first positioning mechanism. Then, the web 401 is transported between the two side wing plates 402 and in a horizontal state. Then, the two side wing plates 402 are driven toward each other by the first positioning mechanism and fit into the web 401, thereby achieving Now the wing plate 402 is positioned again. After the wing plate 402 is positioned, the height of the web 401 between the two side wing plates 402 is adjusted by the second positioning mechanism so that the contact surface between the web 401 and the wing plate 402 is located in the middle position of the wing plate 402. In this embodiment, before welding the sound barrier steel structure 4, there is no need to use manual pre-spot welding. The two groups of wing plates 402 to be welded and one group of web plates 401 can be directly positioned in the second U-groove 305 through the positioning mechanism. In the positioning process, it can be ensured that the web 401 is located in the center position between the two side wing plates 402 to improve the welding accuracy.

[0055] See also Figure 4-Figure 6 The first positioning mechanism includes a U-shaped frame symmetrically arranged on one side of the second U-groove 305, and the U-shaped frame includes a vertical plate 605. The two ends of the vertical plate 605 are symmetrically fixed with a top plate 606 and a bottom plate 607, wherein the positioning plate 303 is symmetrically fixed with supports 312, and a first screw 602 is rotatably arranged between the two sets of supports 312. The threads on both sides of the first screw 602 rotate in opposite directions. A first motor 604 is fixed on one side of the support 312, and the driving end of the first motor 604 is fixed to the first screw 602. A first nut 603 is symmetrically spirally sleeved on the first screw 602, and the first nut 603 is fixed to the bottom end of the vertical plate 605;

[0056] It should also be noted that when positioning the wing panels 402, first, the two sets of wing panels 402 are clamped into the U-shaped frame by using a lifting device, and the upper and lower sides of the wing panels 402 are respectively in contact with the top plate 606 and the bottom plate 607. When the web 401 is moved between the wing panels 402 on both sides, the first motor 604 is started to drive the first screw 602 to rotate, and the first nuts 603 on both sides respectively drive the U-shaped frames toward each other, thereby synchronously driving the wing panels 402 to move toward the web 401 until one side of the wing panel 402 is in contact with the web 401 and the other side is in contact with the vertical plate 605.

[0057] In this embodiment, please refer to Figure 4-Figure 7The second positioning mechanism includes an upper splint 6 and a lower splint 601 arranged on one side of the second U-groove 305. The upper splint 6 and the lower splint 601 are symmetrically arranged with the horizontal plane where the axis of the positioning plate 303 is located as the symmetrical plane. The second positioning mechanism also includes a mounting plate 502. A second screw 609 is rotatably arranged on the mounting plate 502. The two sides of the second screw 609 have opposite rotation directions. The second nut 610 is symmetrically spirally sleeved on the second screw 609. A second motor 608 is fixedly arranged on the mounting plate 502. The driving end of the second motor 608 is fixed to the second screw 609. A set of second nuts 610 is fixed to the upper splint 6, and the other end of the second nut 610 is fixed to the lower splint 601. ; It can be explained that, after the positioning of the two side wing plates 402 of this embodiment is completed, the end of the adjustable web 401 is located between the upper clamping plate 6 and the lower clamping plate 601, and the second motor 608 is started to drive the second screw 609 to rotate, so as to drive the second nuts 610 on both sides to move closer together, and then drive the upper clamping plate 6 and the lower clamping plate 601 to move closer to each other, driving the web 401 to rise or fall in the two side wing plates 402. When the web 401 is in contact with the upper clamping plate 6 and the lower clamping plate 601, it means that the web 401 moves to the middle position of the wing plates 402. In this embodiment, there is no need to use measurement to perform positioning when adjusting the position of the web 401, so the positioning accuracy of the web 401 can be guaranteed.

[0058] At the same time, since the center of gravity axis of the web 401 is coaxial with the central axis of the positioning plate 303, when the rotating part drives the positioning plate 303 to rotate, the center of gravity axis of the web 401 and the central axis of the positioning plate 303 can also always remain coaxial. When the web 401 rotates 180 degrees, its position coincides with the initial position, so that after the weld on one side of the sound barrier steel structure 4 is welded, as it rotates 180 degrees, the positions of the welds on both sides are replaced, and the weld position will not change. Therefore, there is no need for the welding robot 104 to re-identify and locate the weld, and welding can be carried out directly, thereby improving welding efficiency and stability.

[0059] In order to adjust the relative positions of the upper and lower clamping plates 601 and the web 401, in this embodiment, reference may be made to Figure 4-Figure 7 An L-shaped bracket 5 is fixedly arranged on the side where the positioning plates 303 on both sides are away from each other, and a driving cylinder 501 is fixedly arranged on the L-shaped bracket, and the driving end of the driving cylinder 501 is fixed to the mounting plate 502; it can be explained that when the web 401 needs to be positioned, the mounting plates 502 on both sides are driven close to each other by the driving cylinder 501, so that the ends of the web 401 can be embedded between the upper splint 6 and the lower splint 601. When one side of the sound barrier steel structure 4 is welded, the driving cylinders 501 on both sides drive the mounting plates 502 away from each other to avoid interference with the rotation of the sound barrier steel structure 4 by the upper splint 6 and the lower splint 601.

[0060] As a further solution of this embodiment, please refer to Figure 7-Figure 9 , after the sound barrier steel structure 4 is flipped 180 degrees, in order to avoid the positioning plate 303 interfering with the welding of the welding robot 104, this embodiment requires the rotating part to drive the positioning plate 303 to reset to the initial position, so that the welding robot 104 can weld smoothly along the second U-groove 305, and the L-shaped bracket 5 is also provided with a support plate 7, which is connected to the lifting mechanism arranged on the L-shaped bracket 5; it can be explained that in the initial state, the upper surface of the support plate 7 is flush with the upper surface of the bottom plate 607, so when hoisting the wing plate 402, the wing plate 402 can be first supported by the support plate 7 to ensure the stability of the hoisting, and then the wing plate 402 can be slid into the U-shaped frame;

[0061] Correspondingly, after one side of the sound barrier steel structure 4 is welded, in order to avoid interference with its rotation caused by the presence of the support plate 7, the support plate 7 can be driven down a certain distance by the lifting mechanism to ensure the stable rotation of the sound barrier steel structure 4; when the sound barrier steel structure 4 rotates 180 degrees, the support plate 7 can be driven up by the lifting mechanism to support the sound barrier steel structure 4 again, and then, the U-shaped frames on both sides are separated from the sound barrier steel structure 4, so that the rotating part can drive the positioning plate 303 to rotate and reset to avoid interference.

[0062] In addition, after the sound barrier steel structure 4 is positioned in the second U-groove 305, there is a certain distance between the sound barrier steel structure 4 and each groove wall of the second U-groove 305 to avoid interference between the positioning plate 303 and the sound barrier steel structure 4 when rotating.

[0063] See also Figure 7-Figure 9The lifting mechanism includes a positioning plate 505 fixed on the L-shaped bracket 5, and a third screw 705 is rotatably arranged on the positioning plate 505. The threads on both sides of the third screw 705 rotate in opposite directions, and a third nut 703 is symmetrically spirally sleeved on the third screw 705. The lifting rod 702 is rotatably arranged on the third nut 703, and the other end of the lifting rod 702 is rotatably connected to the support plate 7. Among them, the two ends of the third screw 705 are respectively fixed with the first gear 701, and the driving frames 503 are respectively fixed on both sides of the bottom of the mounting plate 502. The driving frame 503 is fixed on one side of the positioning plate 303 for engaging with the first gear 701. It can be explained that when the mounting plate 502 is in the initial position, the rack 504 is located on the first gear 701 and is close to The rack 504 is engaged with the first gear 701 and drives the third screw 705 to rotate. The third nut 703 can drive the support plate 7 to descend to a certain height through the lifting rod 702. This embodiment does not require the use of other servo motors to drive the third screw 705 to rotate, which not only saves costs but also improves the stability of its movement.

[0064] It should be noted that the screw and nut transmission mechanisms of this embodiment are all existing technologies, and this embodiment does not limit their specific structures and signals.

[0065] In this embodiment, a guide rod 704 is fixedly arranged on one side of the support plate 7, and the other end of the guide rod 704 is slidably plugged into the positioning plate 505, further improving the stability of the support plate 7 when lifting and lowering.

[0066] Also, see Figure 2 、 Figure 4-Figure 6 , several groups of rollers 307 are rotatably arranged on the outer surface of the positioning plate 303, and the rollers 307 roll and abut against the inner surface of the positioning ring 302, wherein the rotating part includes a gear ring 306 fixed on the positioning plate 303, and at least one group of third motors 311 is fixedly arranged on the outer side of the positioning seat 301, and the driving end of the third motor 311 is fixedly provided with a second gear 308 engaged with the gear ring 306; specifically, in this embodiment, the second gear 308 can be driven to rotate by the third motor 311, and the second gear 308 can drive the positioning plate 303 to rotate by engaging with the gear ring 306, so as to realize the angle adjustment of the sound barrier steel structure 4.

[0067] Specifically, an annular track 309 is further provided on one side of the inner edge of the positioning ring 302, and an annular seat 310 is correspondingly fixed on the positioning plate 303 and is slidably connected to the annular track 309; specifically, this embodiment further improves the stability of the rotation of the positioning plate 303 in the positioning ring 302 by providing a roller 307, an annular track 309 and an annular seat 310.
