[0023] Please refer to Figure 2The limiting structure comprises four guide rods 13, two support frames 14, four hinged seats 15, four guide grooves 16, four limiting blocks 17 and four groups of limiting sliding blocks 18; the four guide rods 13 are connected in the four telescopic rods 2 respectively, the two support frames 14 are connected on the outer end faces of the four guide rods 13 respectively, the four hinged seats 15 are installed on the outer wall faces of the two support frames 14 respectively, the four guide grooves 16 are opened on the four hinged seats 15 respectively, the four limiting blocks 17 are installed in the four guide grooves 16 respectively and are connected with the four guide grooves 16 by springs, and the four groups of limiting sliding blocks 18 are installed on the two side faces of the four limiting blocks 17 respectively.
[0024] Please refer to Figure 3 The moving structure comprises four wheel rods 19, four first limiting grooves 20, four second limiting grooves 21, four displacement encoders 22, four sub-wheels 23 and four main wheels 24; the four wheel rods 19 are sleeved on the four hinged seats 15 respectively, the four first limiting grooves 20 are opened in the inner measures of the four wheel rods 19 respectively, the four second limiting grooves 21 are opened on the upper wall faces of the four wheel rods 19 respectively, the four displacement encoders 22 are connected on the outer end faces of the four wheel rods 19 respectively, the four sub-wheels 23 are connected on the outer end faces of the four displacement encoders 22 respectively, and the four main wheels 24 are connected on the outer wall faces of the four sub-wheels 23.
[0025] Please refer to Figure 2 Two power supply modules 25 are installed in the fixed frame 1, and power supply is performed by the two power supply modules 25 during use.
[0026] Please refer to Figure 2 Two auxiliary illuminating lamps 26 are installed on the lower wall face of the switching sleeve 10, and the two auxiliary illuminating lamps 26 can illuminate the welding seam position during use, thereby enhancing the accuracy of the visual inspection instrument 11.
[0027] Please refer to Figure 4 The four first limiting grooves 20 and the four second limiting grooves 21 are opened along the horizontal and vertical directions of the four wheel rods 19 respectively, and when the four second limiting grooves 21 are aligned with the four limiting blocks 17 during use, the four limiting blocks 17 are reset along the four guide grooves 16, are inserted into the four second limiting grooves 21, and limit the four wheel rods 19.
[0028] Please refer to Figure 4 Two connecting frames 27 are connected between the four guide rods 13, and the two connecting frames 27 are rotated towards the fixed frame 1 during use, so that the two connecting frames 27 drive the four wheel rods 19 to rotate around the four hinged seats 15.
[0029] Please refer to Figure 3Two linkage frames 28 are connected between the four limiting blocks 17. In use, the operator moves the two linkage frames 28 towards the two support frames 14, and the two linkage frames 28 drive the four limiting blocks 17 to slide along the four guide grooves 16 through the four sets of limiting sliding blocks 18, until the four limiting blocks 17 are disengaged from the four first limiting grooves 20.
[0030] In this embodiment, two infrared calibrators 12 are started, and the two infrared calibrators 12 emit infrared rays downward. The operator starts the four telescopic levers 2 to drive the fixed frame 1 to move along the four guide rods 13. When the infrared rays are close to the weld, the four telescopic levers 2 are stopped. Then, the two lead screw motors 4 are started to drive the transmission frame 6 to move through the transmission lead screw 5. The transmission frame 6 moves along the two slide rails 8 through the two slide sleeves 7, until the front and rear infrared rays are both irradiated on the weld.
[0031] Specifically, when the steel box girder weld is in a plane, the operator places the fixed frame 1 above the weld. At this time, the four main wheels 24 support the fixed frame 1. Then, the two infrared calibrators 12 are started, and the two infrared calibrators 12 emit infrared rays downward. The operator starts the four telescopic levers 2 to drive the fixed frame 1 to move along the four guide rods 13. When the infrared rays are close to the weld, the four telescopic levers 2 are stopped. Then, the two lead screw motors 4 are started to drive the transmission frame 6 to move through the transmission lead screw 5. The transmission frame 6 moves along the two slide rails 8 through the two slide sleeves 7, until the front and rear infrared rays are both irradiated on the weld. When the two infrared rays intersect the weld, the fixed frame 1 is lifted and adjusted at a certain angle. When the two infrared rays coincide with the weld, it means that the forward direction of the fixed frame 1 is the direction of the weld. Then, the operator turns off the two infrared calibrators 12 and starts the visual inspection instrument 11. When the visual inspection instrument 11 is started, the two auxiliary illuminating lamps 26 and the four displacement encoders 22 are sequentially started. The operator starts the four main wheels 24 to drive the visual inspection instrument 11 to move forward. The displacement distance is recorded by the four displacement encoders 22. When the visual inspection instrument 11 detects that the weld is unqualified, a photo is taken, and the distance from the initial position is recorded by the four displacement encoders, so that the operator can quickly find the unqualified weld position.
[0032] In this embodiment, the operator moves the two linkage frames 28 towards the two support frames 14, and the two linkage frames 28 drive the four limiting blocks 17 to slide along the four guide grooves 16 through the four sets of limiting sliding blocks 18, until the four limiting blocks 17 are disengaged from the four first limiting grooves 20. At this time, the operator can rotate the two connecting frames 27 towards the fixed frame 1, and the two connecting frames 27 drive the four wheel rods 19 to rotate around the four hinged seats 15. When the four second limiting grooves 21 are aligned with the four limiting blocks 17, the operator releases the four limiting blocks 17, and the four limiting blocks 17 are reset along the four guide grooves 16 and inserted into the four second limiting grooves 21 to limit the four wheel rods 19.
[0033] Specifically, when the steel box girder weld is on the two diagonal rib reinforcement, the operator moves the two linkage frames 28 towards the two support frames 14, and the two linkage frames 28 drive the four limiting blocks 17 to slide along the four guide grooves 16 through the four sets of limiting sliding blocks 18, until the four limiting blocks 17 are disengaged from the four first limiting grooves 20. At this time, the operator can rotate the two connecting frames 27 towards the fixed frame 1, and the two connecting frames 27 drive the four wheel rods 19 to rotate around the four hinged seats 15. When the four second limiting grooves 21 are aligned with the four limiting blocks 17, the operator releases the four limiting blocks 17, and the four limiting blocks 17 are reset along the four guide grooves 16 and inserted into the four second limiting grooves 21 to limit the four wheel rods 19. Then the operator places the fixed frame 1 between the two diagonal rib reinforcements. At this time, the four auxiliary wheels 23 support the fixed frame 1, and after adjusting the horizontal position of the visual inspection instrument 11, since the weld is at the root of the reinforcement, if the two infrared rays still cannot irradiate the weld, the adapter sleeve 10 is started to drive the visual inspection instrument 11 to rotate around the adapter frame 9 until the two infrared rays irradiate the weld position, and then the weld is detected.
