Description

Technical Field

[0001] The invention relates to the technical field of weld detection, in particular to a weld quality detection device for a municipal bridge steel structure. Background Art

[0002] A bridge is a man-made structure that spans a river, lake, ocean, valley or other obstacle. It connects two banks or two places, making traffic, transportation and communication possible. At present, municipal bridges are usually assembled with steel box girders. The steel box girders can be prefabricated in the factory in advance and then assembled on site. This can greatly shorten the construction period and reduce the impact on urban traffic. After the construction of the bridge is completed, the two adjacent steel box girders need to be welded together. Since the welding quality of the two adjacent steel box girders will affect the safety of the bridge, after the welding is completed, the quality of the weld needs to be tested using an ultrasonic flaw detector.

[0003] At present, when using ultrasonic flaw detectors to inspect welds, workers usually squat on the steel box girder, holding the ultrasonic flaw detector in one hand and moving the ultrasonic probe back and forth around the weld in the other hand. Since the steel box girder is relatively long, the weld after welding is also relatively long. Although this operation is simple, squatting for a long time will increase labor intensity, and the temperature on the bridge is very high in the hot summer. It is difficult for workers to continue to inspect the welds in a high temperature environment, which will affect the inspection efficiency of the welds. Summary of the invention

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figure 1-9In an embodiment of the present invention, a municipal bridge steel structure weld quality inspection device includes a moving mechanism 1, a detection mechanism 2, a labeling mechanism 3, a pressing mechanism 4 and a spraying mechanism 5. The moving mechanism 1 is used to drive the device to move as a whole. Two symmetrical fixed plates 12 are fixedly connected to one side of the bottom surface of the moving mechanism 1. An electric push rod 13 is fixedly connected to one side of the fixed plate 12. A cutter 14 is fixedly connected to the output end of the electric push rod 13. A fixing component for fixing an ultrasonic flaw detector is fixedly connected to one end of the top surface of the moving mechanism 1. A camera is fixedly connected to the inner top surface of the fixing component. The detection mechanism 2 is arranged on the bottom surface of the moving mechanism 1 and is used to inspect the weld between two adjacent steel box girders. The detection mechanism 2 includes two symmetrical rectangular frames 21 that are fixedly penetrated and fixed to the top surface of the moving mechanism 1. A reciprocating screw is rotatably connected between the two short side sides of the inner side of the rectangular frame 21. An L-shaped plate 22 is screwed through the outer wall of the reciprocating screw. The top surface of the L-shaped plate 22 A slide plate 23 is provided to slide through, and a notch 231 is provided at the bottom end of the slide plate 23. A bolt 24 is screwed through the bottom end of one side of the slide plate 23. The labeling mechanism 3 is arranged on the bottom surface of the mobile mechanism 1 and is located on both sides of the detection mechanism 2, and is used to mark unqualified welds. The labeling mechanism 3 includes a rectangular frame 2 31 fixedly connected to one end of the top surface of the mobile mechanism 1, and a stud is rotatably connected between the two short side surfaces inside the rectangular frame 2 31. The outer wall of the stud is screwed through with an L-shaped plate 2 32 that slides through the top surface of the mobile mechanism 1. A connecting frame 33 is fixedly connected to one end of the L-shaped plate 2 32, and an electric push rod 2 34 is fixedly connected to the inner side surface of the connecting frame 33. Two symmetrical support plates 37 are fixedly connected to one end of the bottom surface of the mobile mechanism 1 away from the L-shaped plate 2 32. The pressing mechanism 4 is arranged on the top surface of the mobile mechanism 1, and is used to affix a mark to an unqualified weld. The spraying mechanism 5 is arranged at one end of the top surface of the mobile mechanism 1, and is used to spray the coupling agent on the weld.

[0038] Specifically, first, place the probe of the ultrasonic flaw detector in one of the gaps 231 and fix it with the bolt 24, then place the ultrasonic flaw detector in the fixing assembly and fix it, then select two unused rolls of colored tape, one of which is clamped between the two support plates 37, and the other is clamped on the inner top of the connecting frame 33, and select a reel to be clamped on the inner bottom of the connecting frame 33, and wrap one end of the tape at the connecting frame 33 around the outer wall of the reel (the adhesive surface of the pulled tape faces the support plate 37), pull the tape at the support plate 37 apart and bond it to the tape at the connecting frame 33 (such as Figure 5As shown in the figure (the adhesive surface of the opened tape faces the weld), the staff can then place the device at the weld, with the probe of the ultrasonic flaw detector located on one side of the weld, and pour coupling agent into the interior of the spraying mechanism 5. At this time, the staff can control the movement of the moving mechanism 1 by using the remote control, and at the same time control the rotation of the two reciprocating screws by the remote control, and start the spraying mechanism 5 to spray the coupling agent inside it on the weld (this is the prior art, so no further description is given). The rotating reciprocating screw can make the L-shaped plate 22 at the corresponding position drive the probe to reciprocate on the side of the weld through the slide 23, so that the weld can be detected. At the same time, it can be seen through the camera that the ultrasonic The camera is connected to a mobile phone or computer (this technology is prior art and will not be elaborated on here). When the camera shows that the weld quality is unqualified on the display screen of the ultrasonic flaw detector, the cutter 14 at the corresponding position can be moved by starting the electric push rod 13 near the connecting frame 33. Since the part of the tape at the support plate 37 is in a straight state (because one end of the tape at the support plate 37 is bonded to the tape at the connecting frame 33), when the moving cutter 14 contacts the stretched tape, the cutter 14 cuts the stretched tape under the action of the electric push rod 13 at the corresponding position, and at the same time starts the pressing mechanism 4 to cut. The tape is pressed toward the weld, and the pressing mechanism 4 is reciprocated to stick the tape to the weld until a qualified condition appears on the display screen of the ultrasonic flaw detector. At this time, another electric push rod 13 is started to cut the pulled tape, and the tape with both ends cut is completely pasted to the weld through the pressing mechanism 4 (this situation is suitable for use in longer unqualified welds). Alternatively, when the ultrasonic flaw detector detects that the unqualified weld is relatively short, the pulled tape is first sucked by the pressing mechanism 4, and then the two electric push rods 13 are started at the same time to cut both ends of the pulled tape at the same time. At this time, the cut tape is adsorbed on the pressing mechanism 4, and then the cut tape is pasted by the pressing mechanism 4. The adhesive tape at the connecting frame 33 is then pulled apart and the adhesive tape at the connecting frame 33 is then pulled apart and the adhesive tape at the supporting plate 37 is then pulled apart and the adhesive tape at the supporting plate 37 is then pulled apart and the adhesive tape at the connecting frame 33 is then pulled apart and the adhesive tape at the supporting plate 37 is then pulled apart and the adhesive tape at the supporting plate 37 is then pulled apart and the adhesive tape at the connecting frame 33 is then pulled apart and the adhesive tape at the supporting plate 37 is then pulled apart and the adhesive tape at the supporting plate 37 is pulled apart and the adhesive tape at the supporting plate 37 is then pulled apart and the adhesive tape at the connecting frame 33 is then pulled apart and the adhesive tape at the supporting plate 37 is ... Figure 5As shown), when it is necessary to inspect the welds below the steel box girder, the mobile mechanism 1 can be made into a structure similar to a wall-climbing robot so that the device can move on the bottom surface of the bridge. The device installs colored tape at the connecting frame 33 and the two support plates 37, and then the tape can be pasted on the unqualified welds through the cooperation of the two cutters 14 and the pressing mechanism 4, so that the staff can uniformly handle the unqualified welds in the later stage. The staff does not need to manually inspect the welds, which can reduce the labor intensity of the staff and thus improve the inspection efficiency of the welds. Moreover, through the remote control and the coordinated use of the camera, the staff does not need to inspect the welds outdoors, which can avoid the staff from working in hot weather, thereby preventing the staff from getting heatstroke when inspecting the welds outdoors.
