The gear 209 is engaged with the arc-shaped rack 202, and the second motor 208 can drive the gear 209 to rotate. During the rotation of the gear 209, the second limit plate 206 can be driven to rotate along the shape of the arc-shaped rack 202 under the action of the arc-shaped rack 202, thereby causing the X-ray machine 3 to rotate around the welding joint to perform a more comprehensive inspection of the welding joint.

[0037] Further, such as Figure 4 As shown, the outer surface of the arc plate 201 is slidably connected to a first limit plate 205, and a number of connecting rods 207 are fixedly connected between the first limit plate 205 and the second limit plate 206.

[0039] Embodiment 2 of the utility model of the ray detection device

[0040] The utility model of the ray detection equipment further, as Figure 1-Figure 2 As shown, the adjustment mechanism includes a support base 104 installed on the driving mechanism, and a mounting groove 106 is opened on the top of the support base 104. A bidirectional screw rod 107 is rotatably connected to the mounting groove 106 through a bearing. The outer surface of the bidirectional screw rod 107 is threadedly connected to two sliding seats 110. The two sliding seats 110 are respectively fixedly mounted on the bottom ends of the two arc-shaped plates 201. During the rotation of the bidirectional screw rod 107, the inspiration sliding seats 110 can be driven to move closer to or away from each other, and then the two arc-shaped racks 202 can be driven to move closer to or away from each other through the two arc-shaped plates 201.

One end of the hand-tightening bolt 105 penetrates into the support seat 104 and contacts the connecting shaft 103. The position of the support seat 104 can be fixed by the hand-tightening bolt 105. After loosening the hand-tightening bolt 105, the support seat 104 can be rotated around the connecting shaft 103 so that the support seat 104 can extend from the side of the support platform 102. This arrangement allows the rotating device 2 to be extended under the welding joint alone, so that when there are debris on the ground under the welding joint that blocks the passage of the AGV trolley 101, corresponding detection can also be carried out.

The radiation sensor is used to detect radiation during the detection process, and the alarm will sound an alarm when the radiation exceeds the standard to remind people around to stay away or stop the detection.

[0046] During use, the electric telescopic rod drives the support platform 102 to descend, and the first motor 109 drives the bidirectional screw rod 107 to rotate through the reducer 108 so that the two sliding seats 110 move away from each other, and then the AGV trolley 101 moves to the bottom of the welding joint, and then the electric telescopic rod drives the support platform 102 to rise, so that the two arc-shaped racks 202 are located on both sides of the welding joint, and the first motor 109 drives the bidirectional screw rod 107 to rotate through the reducer 108 so that the two sliding seats 110 are close, thereby making the two arc-shaped racks 202 contact, and the positioning rod 203 is inserted into the positioning groove 204, and then the second motor 208 drives the gear 209 to rotate. During the rotation of the gear 209, under the action of the arc-shaped rack 202, the second limit plate 206 is driven to rotate along the shape of the arc-shaped rack 202, thereby making the X-ray machine 3 rotate around the welding joint to detect the welding joint.
