[0025] See also Figure 1 , Figure 4 and Figure 5 , a detection system in an embodiment includes a detection device and a flipping device 10, wherein the detection device can detect the axle box 600 in the support cavity 110. The flipping device 10 includes a support member 100, a clamping member 200 and a rotating member 300, wherein the support member 100 is formed with a support cavity 110, wherein the support cavity 110 is used to place the axle box 600; the clamping member 200 is disposed in the support cavity 110, and the clamping member 200 can rotate relative to the support member 100 along a first direction R1, and the clamping member 200 is used to clamp the axle box 600; the rotating member 300 is connected to the support member 100, and the rotating member 300 is used to drive the support member 100 to drive the clamping member 200 to rotate along a second direction R2, and the second direction R2 intersects with the first direction R1.

[0026] Since the axle box is a part that transfers the weight and load of the locomotive body to the wheels, it is an important component for the safe operation of the locomotive. Therefore, in order to ensure the safe operation of the locomotive, it is necessary to perform magnetic particle inspection on the stress-bearing parts of the axle box in accordance with relevant technical regulations and stress requirements of the stress-bearing parts of the axle box. Magnetic particle inspection is the flaw detection process of the axle box. Since the axle box is an irregular part, in the existing axle box flaw detection process, it is necessary to use an overhead crane to repeatedly lift the axle box and flip it to fix it in order to achieve flaw detection in all positions of the axle box. The repeated lifting process is complicated, wastes a lot of time, and is inefficient. At the same time, in the actual operation process, three or more workers are usually required to lift and flaw-detect the axle box, which has high labor costs, and the cost of multi-person collaboration and communication is high, which is inefficient.

[0027] The detection system and its flipping device 10 in this embodiment first fix the clamping member 200 on the axle box 600, and then transport the axle box 600 to the support cavity 110 of the support member 100 by the overhead crane. When the clamping member 200 is installed on the support member 100, the axle box 600 is also fixed in the support cavity 110. The clamping member 200 can rotate along the first direction R1 relative to the support member 100, so that the axle box 600 can be flipped along the first direction R1 in the support cavity 110. The rotating member 300 can drive the support member 100 to rotate along the second direction R2, so that the support member 100 can drive the axle box 600 to rotate along the second direction R2. When it is necessary to detect the part of the axle box 600 that intersects with the plane where the first direction R1 is located, the axle box 600 can be flipped by rotating the clamping member 200, so that different parts of the axle box 600 that intersect with the first direction R1 are aligned with the detection device for detection. When it is necessary to inspect other parts of the axle box 600 in the first direction R1, the support member 100 can be driven by the rotating member 300 to drive the axle box 600 to rotate along the second direction R2, so that different parts of the axle box 600 in the first direction R1 can be aligned with the detection device for detection. The detection personnel can turn the axle box 600 by rotating the clamping member 200 or driving the rotating member 300 to achieve all-round detection of the axle box 600. The operation is simple and convenient, which is conducive to improving the detection efficiency. At the same time, during the detection process, only one hoisting is required to complete the detection of the axle box 600, which greatly shortens the detection time and improves the detection efficiency.

[0028] See also Figure 2 , Figure 3 and Figure 4In one embodiment, the outer surface of the support member 100 is an arc surface, and a meshing rack 120 is arranged on the arc surface, the length direction of the rack 120 is the second direction R2, and the second direction R2 is the arc direction of the arc surface, and the rotating member 300 includes a gear 310 and a rotation source 320, the gear 310 is meshed with the rack 120, and the rotation source 320 is used to drive the gear 310 to rotate. The rack 120 is arranged on the support member 100 with an arc surface, and the gear 310 is driven to rotate by the rotation source 320, so as to drive the support member 100 to rotate along the second direction R2. The gear 310 and the rack 120 can accurately and stably perform transmission cooperation, and the meshing between the gear teeth has a certain anti-slip effect, which can ensure the accuracy and stability of the support member 100 during the rotation process in the second direction R2, thereby ensuring the safety and reliability of the flip device 10.

[0029] In another embodiment, the outer surface of the support member 100 is an arc surface, and a meshing rack 120 is arranged on the arc surface, the length direction of the rack 120 is the second direction R2, and the second direction R2 is the arc direction of the arc surface, the rotating member 300 includes a worm and a rotation source 320, the worm is meshed with the rack 120, and the rotation source 320 is used to drive the worm to rotate. The support member 100 and the rotating member 300 are driven by a worm gear, and the worm gear transmission has continuity and stable transmission, so that the flip device 10 has good structural stability.

[0030] In other embodiments, the support member 100 and the rotating member 300 may be transmitted in other ways, as long as the support member 100 can be rotated in the second direction R2. Specifically, the rotation source 320 is a motor. It can also be other equipment that can drive the gear 310 or the worm to rotate.

[0031] See also Figure 1 , Figure 2 and Figure 4 In one embodiment, the flipping device 10 of the detection system further includes a base 400, wherein a receiving cavity 410 is formed in the base 400, and a limited space is formed on the inner wall of the receiving cavity 410, wherein the support member 100 is in contact with the inner wall of the limited space, and the support member 100 can rotate along the second direction R2 in the limited space. The base 400 can make the support member 100 more stable. Since the support member 100 is in contact with the inner wall of the limited space, the inner wall of the limited space can provide a certain limited support to the support member 100 when the support member 100 rotates, thereby ensuring the stability of the rotation of the support member 100 in the second direction R2, and improving the operational stability and safety of the flipping device 10.

[0032] See also Figure 1 and Figure 4 In one embodiment, the flipping device 10 of the detection system further includes a first limiting column 430 and a second limiting column 420, the support member 100 is a circular arc plate structure, the inner arc surface of the circular arc plate-shaped support member 100 forms the support cavity 110, the first limiting column 430 abuts against the inner arc surface of the support member 100, the second limiting column 420 abuts against the outer arc surface of the support member 100, and the limiting space is formed between the first limiting column 430 and the second limiting column 420. The support member 100 of the circular arc plate structure has the first limiting column 430 and the second limiting column 420 abutted on the inner and outer arc surfaces respectively. The first limiting column 430 and the second limiting column 420 can provide a certain support for the support member 100, so that the support member 100 can stably run in the second direction R2.

[0033] Furthermore, if Figure 1 and Figure 5 As shown, there are a plurality of first limiting posts 430 and a plurality of second limiting posts 420, and the plurality of first limiting posts 430 can be rotatably abutted against the inner arc surface of the support member 100, and the plurality of second limiting posts 420 can be rotatably abutted against the outer arc surface of the support member 100, and the plurality of first limiting posts 430 are arranged at intervals along the second direction R2, and the plurality of second limiting posts 420 are arranged at intervals along the second direction R2, and the limiting space is formed between the plurality of first limiting posts 430 and the plurality of second limiting posts 420. The plurality of first limiting posts 430 and the second limiting posts 420 can make the supporting force on the support member 100 more stable, reduce the rotation pressure of the rotating member 300 from the support member 100, and ensure the operation stability and structural reliability of the flip device 10. The first limiting column 430 and the second limiting column 420 can be rotatably abutted against the inner and outer arc surfaces of the support member 100, which can reduce the rotational friction between the support member 100 and the first limiting column 430 and the second limiting column 420, so that the support member 100 can rotate more smoothly in the second direction R2. At the same time, multiple first limiting columns 430 and second limiting columns 420 can provide support for the support member 100, ensuring that the inspection worker can also perform flip inspection on the axle box 600 when alone, thereby improving the inspection efficiency and the convenience of using the flipping device 10.

[0034] In one embodiment, the outer surface of the first limiting column 430 can fit the inner arc surface of the support member 100. The curvature of the outer surface of the first limiting column 430 is equal to the curvature of the inner arc surface of the support member 100. The first limiting column 430 can fit the support member 100 more closely, making the operation of the support member 100 more stable and reliable. Figure 1 and Figure 3 In one embodiment, a placement opening is provided on the support member 100 of the arc plate structure, and the length of the placement opening is greater than the maximum length of the axle box 600. Specifically, the central angle of the support member 100 of the arc plate structure ranges from 270° to 300°. The placement opening facilitates the lifting of the axle box 600 into the support cavity 110, and then only one lifting worker and one inspection worker are required to complete the lifting and flipping of the axle box 600, thereby improving the convenience of use of the flipping device 10.

[0036] Furthermore, a ball bearing is arranged in the limiting groove, and the number of the ball bearings is multiple, and the multiple ball bearings respectively contact the inner arc surface and the outer arc surface of the support member 100. The ball bearings can reduce the rotational friction between the support member 100 and the inner wall of the limiting groove, and make the rotation of the support member 100 smoother while ensuring the stable rotation of the support member 100.

[0037] In one embodiment, the base 400 is further provided with a collecting slot, which is located on the bottom wall of the accommodating cavity 410, and is used to collect the detection magnetic powder.
