Description

Technical Field

[0001] This utility model belongs to the field of guardrail laser welding technology, and in particular relates to a road guardrail laser welding equipment. Background Technology

[0002] Traffic guardrails are traffic safety facilities installed on the outer side of road shoulders, traffic dividers, and pedestrian curbs. Their functions include preventing vehicles from running off the road and causing rollover accidents. Especially when installed on mountain curves and dangerous sections of road, traffic guardrails can attract the attention of drivers from a distance, increasing their vigilance. They also provide visual guidance to drivers when passing through, helping them to make correct maneuvers. They can prevent head-on collisions with oncoming vehicles, as well as collisions between vehicles traveling in the same direction. They can also prevent vehicles from hitting pedestrians and prevent pedestrians from jaywalking.

[0003] Road guardrails are generally composed of two sets of spaced longitudinal bars and multiple sets of cross bars that connect the longitudinal bars. In order to maintain the strength of the weld points, it is generally necessary to weld the weld points on both the top and bottom of the guardrail. This requires that after the welds on the top of the longitudinal bars and cross bars are completed, the guardrail is flipped so that the unwelded side faces up. The flipping process results in low welding efficiency. Utility Model Content

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please see Figure 1-6 As shown, this utility model is a laser welding equipment for road guardrails, including a welding main chamber 1, a guardrail support platform 2 set on one side of the welding main chamber 1, and a welding support platform 17 installed inside the cavity of the welding main chamber 1. The welding main chamber 1 is designed as a semi-enclosed wall, with its opening connected to the guardrail support platform 2. Guide platforms 3 are set above both the guardrail support platform 2 and the welding support platform 17. A driving structure is set inside the guide platform 3. The driving structure is used to push the guardrail placed above the guardrail support platform 2 into the welding main chamber 1. The connection points of the guardrail are welded inside the welding main chamber 1. After welding is completed, the guardrail is pulled out in the opposite direction by the drive of the guide platform 3.

[0027] The support guide plate 5 is mounted on the welding support platform 17, and four sets of support guide plates 5 are arranged. The upper and lower sets of support guide plates 5 are opposite each other. A crossbeam plate 8 is arranged between the two sets of support guide plates 5, and the crossbeam plate 8 is perpendicular to the support guide plate 5. The two sets of support guide plates 5 are positioned above the guardrail after it is moved to that position, so as not to affect the movement of the guardrail. A limiting crossbeam 6 is fixed on the opposite side of each set of support guide plates 5, and a rack is provided at the bottom of the limiting crossbeam 6. A toothed disc part 13 is provided at the bottom of the limiting crossbeam 6. The toothed disc part 13 is meshed with the rack at the bottom of the limiting crossbeam 6. That is, when the toothed disc part 13 rotates, it can drive the toothed disc part 13 to move along the bottom of the limiting crossbeam 6. A synchronous support roller 12 is sleeved on the surface of the toothed disc part 13. At the same time, the synchronous support roller 12... A support plate 7 is fixedly provided on the side of the 2, so that the bent part of the support plate 7 is attached to the top of the support guide plate 5. The support plate 7 provides support for the synchronous support roller 12, and the cross frame plate 8, which is fixedly connected to the other side of the support plate 7, is suspended between the two sets of support guide plates 5. Each set of cross frame plates 8 is provided with support plates 7 at both ends, so the stability of the cross frame plate 8 can be maintained. A drive motor 9 and a gearbox 10 are installed on the side of the cross frame plate 8, and the two ends of the gearbox 10 are connected to the synchronous support roller 12 through the drive shaft 11. Under the drive connection of the drive motor 9 and the gearbox 10, the drive shaft 11 synchronously drives the gear plate part 13 to rotate, and then the gear plate part 13 rotates synchronously and moves radially below the limiting cross plate 6 to adjust the position of the cross frame plate 8. The other side of the crossbeam plate 8 is reinforced with a cylinder mounting base 14 by bolts, and a drive cylinder 15 is installed on the side of the cylinder mounting base 14. The output end of the drive cylinder 15 is connected to the welding head body 16 through the support plate, so that the welding head of the welding head body 16 faces the connection point of the guardrail crossbeam and the longitudinal bar. The upper two sets of limiting horizontal plates 6 can be connected to two sets of horizontal frame plates 8, and the welding head bodies 16 on one side of the two sets of horizontal frame plates 8 are distributed in a V-shape. Since the connection points of the guardrail horizontal bars and vertical bars are on both sides of the horizontal bars, the V-shaped distribution design of the two sets of welding head bodies 16 allows the welding head of the welding head body 16 to extend into the welding point, and the welding head can be driven by the drive cylinder 15 to approach the welding point for welding. The lower two sets of support guide plates 5 are also connected to two sets of horizontal frame plates 8, and the V-shaped openings of the lower two sets of welding head bodies 16 face upwards, so that the four sets of welding heads can be aligned with the welding point simultaneously. In this way, as the horizontal frame plates 8 move, the upper and lower welding points of the guardrail can be welded quickly without the need to flip the guardrail.

[0028] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
