Description

Technical Field

[0001] This utility model relates to the field of highway construction technology, specifically to a highway guardrail welding device. Background Technology

[0002] As a core component of road safety protection, the welding quality of highway guardrails directly affects the durability of road facilities and driving safety. Traditional guardrail welding mainly relies on manual labor or semi-automatic equipment, resulting in prominent problems such as low production efficiency, high labor intensity, and significant influence of human factors on weld quality. With the improvement of highway construction standards and the expansion of production capacity demand, automated welding technology has been gradually applied. However, existing equipment is mostly limited to single-station, fixed-post operation, making it difficult to adapt to the processing needs of multi-segment splicing of guardrails, different length specifications, and complex weld positions.

[0003] Although the welding equipment currently on the market can achieve basic automated conveying and positioning, it has the following problems: First, the workpiece clamping system generally lacks the ability to adjust quickly and has poor compatibility with guardrails of different lengths; Second, the welding station is mostly fixed in layout, making it difficult to achieve continuous multi-angle operation of the weld seam through rotation or lateral displacement.

[0006] The fixing mechanism includes: a support base, a support ring disposed in the support base, and a fixing component disposed on the support ring;

[0007] The fixing component is adapted to the guardrail panel and includes: a telescopic structure, a fixing frame connected to the telescopic structure, a roller connected to the fixing frame, and a second motor connected to the roller;

[0008] The bottom of the support base is provided with a first slider structure that is adapted to the first guide rail structure.

[0009] Preferably, the fixing mechanism further includes: a third motor, a transmission gear connected to the third motor, and a gear disk adapted to the transmission gear, wherein the gear disk is connected to the support ring.

[0013] Preferably, the inner side of the welding frame also has a second rack structure, and the welding base also includes a fourth motor and a second gear structure disposed on the fourth motor, wherein the second gear structure is adapted to the second rack structure.

[0014] Preferably, the first guide rail structure is an I-shaped structure, and the first slider structure is adapted to the first guide rail structure.

[0015] By adopting the above technical solution, this utility model mainly has the following technical effects:

[0016] 1. By controlling the lateral displacement of the robotic arm and combining it with the rotational positioning of the support ring, the technical problem of the welding station being unable to achieve continuous multi-angle operation of the weld seam through rotation or lateral displacement is solved. This achieves the technical effect of eliminating human operation error, effectively suppressing welding deformation, and improving the uniformity of weld formation.

[0030] Please see Figures 1-6 This utility model provides a welding device for highway guardrails, which includes: a support mechanism 1, a fixing mechanism 2 disposed on the support mechanism 1, and a welding mechanism 3 adapted to the support mechanism 1 and the fixing mechanism 2.

[0031] In some embodiments, the support mechanism 1 is a part of the guardrail welding device used to fix and support components, which includes: a support frame 11 and a first guide rail structure 12 disposed on the support frame 11; in some embodiments, the support frame 11 is a bracket structure with a certain rigidity and height, which can be used to support the guardrail for welding, and the first guide rail structure 12 is arranged along the length direction of the support frame 11 and is movably connected to the fixing mechanism 2, so that the fixing mechanism 2 can move along the length direction of the support frame 11.

[0032] In some embodiments, the fixing mechanism 2 is a part of the guardrail welding device used to fix and support the guardrail, and includes: a support base 21, a support ring 22 disposed in the support base 21, and a fixing component 23 disposed on the support ring 22. The support base 21 is movably connected to the first guide rail structure 12. Specifically, the bottom of the support base 21 is provided with a first slider structure 211 adapted to the first guide rail structure 12. The movement of the fixing mechanism 2 is realized by the first slider structure 211 sliding on the first guide rail structure 12.

[0033] In some embodiments, the support ring 22 is a hollow structure, and the guardrail can pass through the hollow part of the support ring 22, thereby using the support ring 22 to support the guardrail.

[0034] In some more preferred embodiments, the inner side of the support frame 11 also includes a first rack structure 111, and the support base 21 also includes a first motor 212 and a first gear structure 213 disposed on the first motor 212. The first gear structure 213 is adapted to the first rack structure 111. The first motor 212 drives the first gear structure 213 to rotate, and the first rack structure 111 drives the fixing mechanism 2 to move along the setting direction of the first rack structure 111. By adjusting the spacing between the fixing mechanisms 2, it can accommodate guardrails of different lengths and enhance practicality.

[0035] In some embodiments, the first guide rail structure 12 is an I-shaped structure, and the first slider structure 211 is adapted to the first guide rail structure 12. On the one hand, the first guide rail structure 12 loads the first slider structure 211 to move, and on the other hand, the upper flange structure of the first guide rail structure 12 can be used to limit the fixing mechanism 2 to prevent the fixing mechanism 2 from overturning.

[0036] Furthermore, the fixing component 23 is adapted to the guardrail panel and is used to limit the guardrail panel when it abuts against it. It includes: a telescopic structure 231, a fixing frame 232 connected to the telescopic structure 231, a roller 233 connected to the fixing frame 232, and a second motor 234 connected to the roller 233. The output end of the telescopic structure 231 is connected to the fixing frame 232. The telescopic structure 231 can be any of an electric telescopic rod or a telescopic cylinder. Through the extension and retraction of the telescopic structure 231, the roller 233 abuts against the guardrail panel and is then limited in position.

[0037] In some embodiments, the roller 233 is rotatably connected to the fixed frame 232, and the second motor 234 is driven by the roller 233. For example, the second motor 234 can be connected to the roller 233 through a belt pulley transmission structure or through a chain and sprocket structure. The above design allows the fixed component 23 located above the guardrail to separate from the guardrail and lose its limiting function. Then, the roller 233 can be driven to rotate by the second motor 234, and the guardrail can be transported in a predetermined direction by the roller 233.

[0038] In some more preferred embodiments, the support base 21 is rotatably connected to the support ring 22. The above design allows the fixing component 23 to limit the position of the guardrail after it comes into contact with the guardrail, and then the angle of the guardrail is finely adjusted by rotating the transmission support ring 22. This solves the technical problem that traditional welding requires multiple disassemblies and adjustments of the workpiece posture when there are straight sections, curved sections and inclined sections of highway guardrails, and the weld is always in the best flat welding position.

[0039] Furthermore, the fixing mechanism 2 also includes: a third motor 24, a transmission gear 25 connected to the third motor 24, and a gear disk 26 adapted to the transmission gear 25, wherein the gear disk 26 is connected to the support ring 22, so that the rotation of the third motor 24 drives the rotation of the gear disk 26 through the transmission gear 25, thereby realizing the function of rotating the support ring 22.

[0040] In some embodiments, the welding mechanism 3 is a part of the guardrail welding device used for welding guardrail panels, comprising: a welding frame 31, a welding base 32 disposed on the welding frame 31, a robotic arm 33 disposed on the welding base 32, and a welding head 34 connected to the robotic arm 33, wherein the robotic arm 33 is used to adjust the position of the welding head 34. In some embodiments, the robotic arm 33 may be a four-axis or six-axis articulated robotic arm, which fixes the welding head 34 and adjusts the welding point of the welding head 34 by connecting flange and welding torch holder. In some embodiments, the welding head 34 can locally heat the base material by means of electric arc or other means, so that the materials of the workpiece to be welded achieve atomic-level bonding and form a permanent connection.

[0041] In some more preferred embodiments, the welding base 32 is movably connected to the welding frame 31. Specifically, the welding frame 31 is provided with a second guide rail structure 311, and the bottom of the welding base 32 is provided with a second slider structure 321 adapted to the second guide rail structure 311. The movement of the welding base 32 is realized by the second slider structure 321 sliding on the second guide rail structure 311.

[0042] In some more preferred embodiments, the inner side of the welding frame 31 also includes a second rack structure 312, and the welding base 32 further includes a fourth motor 322 and a second gear structure 323 disposed on the fourth motor 322. The second gear structure 323 is adapted to the second rack structure 312. The fourth motor 322 drives the second gear structure 323 to rotate, and the second rack structure 312 drives the welding base 32 to move along the setting direction of the second rack structure 312. By adjusting the position of the welding base 32 on the welding frame 31, the weld point of the welding head 34 can be adjusted.

[0043] Finally, it should be noted that the embodiments disclosed in this utility model are merely preferred embodiments of this utility model and are only used to illustrate the technical solutions of this utility model, not to limit it. Although this utility model 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 of the technical features.
