Specific embodiments

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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.

[0030] Refer to Figure 1 - Figure 9 , the intelligent welding equipment for the grid structure of large-span high-speed railway stations, includes a bracket 1 and a welding equipment main body 2, and further includes:

[0031] A first mounting frame 3, the welding equipment main body 2 is installed on the first mounting frame 3, an adjusting mechanism for the angle of the welding equipment main body 2 is provided on the first mounting frame 3, and an adjusting component for adjusting the distance between the welding equipment main body 2 and the circumferential weld is provided on the first mounting frame 3;

[0032] The annular plate 32 is arranged on the adjusting assembly, and a cleaning assembly for cleaning the circumferential weld is arranged on the annular plate 32;

[0033] During use, the hollow ball and the steel pipe are arranged on the support frame and positioned and clamped. After clamping, one end of the steel pipe abuts against the hollow ball, and the abutting position of the hollow ball and the steel pipe is the circumferential weld to be welded. The main body 2 of the welding device is made to weld around the circumferential weld. The welding trajectory of the main body 2 of the welding device around the circumferential weld is adjusted through the adjusting assembly, so that the diameter of the welding trajectory is adapted to the diameter of the circumferential weld, achieving the purpose of making the welding device adapt to hollow balls and steel pipes of different sizes. Then, the angle of the main body 2 of the welding device is adjusted through the adjusting mechanism on the first mounting frame 3, so that the angle between the main body 2 of the welding device and the circumferential weld is within a suitable angle range. The main body 2 of the welding device is started through the PLC to weld around the circumferential weld. After welding, the cleaning assembly can clean the slag and spatter near the circumferential weld.

[0034] Refer to Figure 1 、 Figure 2 and Figure 3 As shown in, the adjusting assembly includes a lifting column 6 fixedly connected to the first mounting frame 3. A vertical shell 4 is slidably connected to the support 1. The annular plate 32 is fixedly connected to the vertical shell 4 through a connecting plate. A sliding groove 5 is formed in the vertical shell 4. The lifting column 6 is slidably inserted into the sliding groove 5. A first motor 7 is fixedly connected to the vertical shell 4 through an L-shaped plate. A first gear 8 is fixedly connected to the output shaft of the first motor 7. An annular rack 9 meshing with the first gear 8 is fixedly connected to the inner wall of the support 1. When it is necessary to adjust the diameter of the welding trajectory of the main body 2 of the welding device to be adapted to the diameter of the circumferential weld, the lifting column 6 moves downward, and the lifting column 6 gradually leaves the sliding groove 5. The lifting column 6 drives the first mounting frame 3 and the main body 2 of the welding device to move until the main body 2 of the welding device moves to a suitable position. The first motor 7 and the main body 2 of the welding device are started through the PLC. The first motor 7 drives the first gear 8 to rotate, so that the first gear 8 travels on the annular rack 9, thereby driving the vertical shell 4 and the main body 2 of the welding device to rotate on the support 1, enabling the main body 2 of the welding device to weld around the circumferential weld. The lifting column 6 slides in the sliding groove 5 to achieve stepless adjustment of the main body 2 of the welding device.

[0035] Refer to Figure 2 、 Figure 3 and Figure 5, a position detection component for detecting the position of the steel pipe is arranged on the bracket 1. The position detection component includes a vertical plate 10 fixedly connected to the bracket 1, a fixed ring plate 11 fixedly connected to the vertical plate 10, a second motor 12 fixedly connected to the vertical plate 10. The output shaft of the second motor 12 is fixedly connected with a second gear 13. A plurality of U-shaped rods 14 are fixedly connected to the fixed ring plate 11. One end of each of the plurality of U-shaped rods 14 is rotatably connected with a rotating ring plate 15. An arc-shaped rack 16 meshing with the second gear 13 is fixedly connected to the rotating ring plate 15. The other ends of the plurality of U-shaped rods 14 are fixedly connected with a connecting ring plate 17. A plurality of sliding rods 18 surrounding the outer side of the steel pipe are slidably inserted into the connecting ring plate 17. One end of the sliding rod 18 is fixedly connected with a semi-sphere 19. A spring 20 is fixedly connected between the semi-sphere 19 and the connecting ring plate 17. A pressure sensor 21 facing the steel pipe is installed at the other end of the sliding rod 18. A plurality of semi-circular blocks 22 are fixedly connected to the inner wall of the rotating ring plate 15. The semi-sphere 19 is located on the trajectory of the semi-circular block 22 rotating around the center of the rotating ring plate 15; when the external support frame positions and clamps the steel pipe, the second motor 12 is started through the PLC. The second motor 12 drives the second gear 13 to rotate. The second gear 13 drives the rotating ring plate 15 to rotate at one end of the U-shaped rod 14 through the arc-shaped rack 16. The rotating ring plate 15 drives a plurality of semi-circular blocks 22 to rotate. The semi-circular blocks 22 can press the semi-spheres 19 on the trajectory. A plurality of semi-spheres 19 are simultaneously pressed towards the steel pipe. The semi-sphere 19 drives the pressure sensor 21 to move through the sliding rod 18. The spring 20 is compressed, so that a plurality of pressure sensors 21 are simultaneously abutted against the outer wall of the steel pipe, and a plurality of pressure sensors 21 are kept within a certain range. If the value of a certain pressure sensor 21 is not within this range, it means that the position of the steel pipe is deviated and needs to be corrected in time. The position states such as the height and angle of the steel pipe are adjusted through the external support frame until the values of all the pressure sensors 21 are within the specified range, so as to achieve the purpose of correcting the position of the steel pipe. Then, the first motor 7 and the welding equipment main body 2 can be started through the PLC for welding.

[0036] Refer to Figure 3 , Figure 4 and Figure 5, a threaded rod 23 is rotatably connected to the vertical shell 4. A moving plate 24 is threadedly connected to the outer wall of the threaded rod 23. A resisting column 25 is fixedly connected to the moving plate 24. An avoidance hole 26 facing the resisting column 25 is formed in the vertical shell 4. A telescopic plate 27 is fixedly connected to the bottom of the moving plate 24. The bottom end of the telescopic plate 27 is fixedly connected to a telescopic sleeve 28. One end of the telescopic sleeve 28 is fixedly connected to the lifting column 6. The other end of the telescopic sleeve 28 is fixedly connected to a vertical rod 29. The bottom end of the vertical rod 29 is fixedly connected to an insertion rod 30. A jack 31 is formed in one of the semi-spheres 19. The insertion rod 30 is inserted into the jack 31. When the PLC starts the second motor 12 to detect the position of the steel pipe through the pressure sensor 21, the semi-sphere 19 will move towards the steel pipe. One of the semi-spheres 19 drives the vertical rod 29 to move towards the steel pipe through the jack 31 and the insertion rod 30. The vertical rod 29 drives the lifting column 6 to move towards the steel pipe through the telescopic sleeve 28, so that the lifting column 6 gradually slides out of the sliding groove 5, thereby achieving the purpose of adjusting the welding track diameter of the welding equipment main body 2. After the adjustment is completed, rotate the rotating block at one end of the threaded rod 23 to drive the threaded rod 23 to rotate. The threaded rod 23 drives the moving plate 24 to move. The moving plate 24 drives the resisting column 25 to be inserted into the avoidance hole 26 and abut against the side wall of the lifting column 6 to lock the lifting column 6. At the same time, the moving plate 24 can drive the vertical rod 29 and the insertion rod 30 to move through the telescopic plate 27, so that the insertion rod 30 leaves the jack 31, that is, the welding track diameter of the welding equipment main body 2 is adjusted; the rotating block at one end of the threaded rod 23 can be replaced with a driving device, which is also controlled by the PLC.

[0037] Refer to Figure 2 and Figure 6 , the cleaning assembly includes an electric push rod 33 fixedly connected to the circular ring plate 32. The output end of the electric push rod 33 is provided with a cleaning sleeve 34. The cleaning sleeve 34 faces the circumferential weld. During the welding process, the PLC starts the electric push rod 33. The electric push rod 33 drives the cleaning sleeve 34 to move towards the circumferential weld, so that the cleaning sleeve 34 contacts the circumferential weld and its vicinity. The vertical shell 4 rotates on the support 1 and can drive the electric push rod 33 and the cleaning sleeve 34 to rotate around the circumferential weld through the circular ring plate 32, so that the cleaning sleeve 34 can clean the slag and spatter attached to the circumferential weld and its vicinity.

[0038] Refer to Figure 6 and Figure 8, a box body 35 is fixedly connected to the output end of the electric push rod 33. An inner cavity 36 is arranged inside the box body 35. A plurality of fixed sleeves 37 communicating with the inner cavity 36 are fixedly connected to the box body 35. A moving column 38 is slidably inserted into the fixed sleeve 37. A cleaning sleeve 34 is fixedly connected to one end of the plurality of moving columns 38; a liquid is arranged inside the inner cavity 36 and the fixed sleeve 37. Starting the electric push rod 33 can drive the box body 35 and the cleaning sleeve 34 to move towards the circumferential weld, so that one end of the plurality of moving columns 38 abuts against the outer walls of the hollow ball and the steel pipe through the cleaning sleeve 34. Part of the moving columns 38 are first pressed into the fixed sleeves 37, so that the cleaning sleeve 34 deforms to adapt to the circumferential weld.

[0039] Refer to Figure 6 , a second mounting bracket 39 is fixedly connected to the box body 35 through a fixed column. An electromagnetic ultrasonic flaw detector 40 for detecting the quality of the circumferential weld is installed on the second mounting bracket 39. An adjusting mechanism for adjusting the angle of the electromagnetic ultrasonic flaw detector 40 is arranged on the second mounting bracket 39; before welding, the angle of the electromagnetic ultrasonic flaw detector 40 is adjusted through the adjusting mechanism on the second mounting bracket 39. During the cleaning process of the circumferential weld by the cleaning sleeve 34, the quality of the circumferential weld can be detected by the electromagnetic ultrasonic flaw detector 40.

[0040] Refer to Figure 6 and Figure 7 , a marking component for marking the defective position of the circumferential weld is arranged on the second mounting bracket 39. The marking component includes an L-shaped shell 41 fixedly connected to the second mounting bracket 39 through an L-shaped column. A sliding plate 42 is arranged inside the L-shaped shell 41. A marking pen 43 and an iron block 44 are fixedly connected to the sliding plate 42. An electromagnet 45 is fixedly connected to one end of the L-shaped shell 41. An elastic connecting rope 46 is fixedly connected between the bottom of the sliding plate 42 and the bottom of the L-shaped shell 41. An L-shaped sliding groove 47 is opened inside the L-shaped shell 41. The sliding plate 42 slides in the L-shaped sliding groove 47 through a slider; when the electromagnetic ultrasonic flaw detector 40 detects that there is a defect in a certain circumferential weld, the electromagnetic ultrasonic flaw detector 40 feeds back the information to the PLC, and the electromagnet 45 is turned on through the PLC. After the electromagnet 45 is energized, it generates a magnetic force to attract the iron block 44. The iron block 44 can drive the sliding plate 42 and the marking pen 43 to move along the L-shaped sliding groove 47, that is, move upward first and then move towards the electromagnet 45. The connecting rope 46 is stretched. The marking pen 43 moves upward to contact the outer wall of the steel pipe. The marking pen 43 moves towards the electromagnet 45 to make a mark on the steel pipe, and the marked position is directly opposite to the electromagnetic ultrasonic flaw detector 40, that is, directly opposite to the defective position of the circumferential weld. After the marking is completed, the electromagnet 45 is turned off through the PLC. Under the action of the connecting rope 46, the marking pen 43 and the sliding plate 42 first move away from the electromagnet 45 and then return to one end of the L-shaped shell 41.

[0041] Working principle: When in use, place the hollow ball and the steel pipe on the support frame and position and clamp them. After clamping, one end of the steel pipe abuts against the hollow ball. The abutting position of the hollow ball and the steel pipe is the circumferential weld to be welded. Make the main body 2 of the welding equipment surround the circumferential weld for welding. Adjust the welding track of the main body 2 of the welding equipment surrounding the circumferential weld through the adjusting component, so that the diameter of the welding track is adapted to the diameter of the circumferential weld, achieving the purpose of making the welding equipment adapt to hollow balls and steel pipes of different sizes. Then, adjust the angle of the main body 2 of the welding equipment through the adjusting mechanism on the first mounting frame 3, so that the angle between the main body 2 of the welding equipment and the circumferential weld is within a suitable angle range. Start the main body 2 of the welding equipment through the PLC to make it surround the circumferential weld for welding. After welding, the slag and spatter near the circumferential weld can be cleaned through the cleaning component;

[0042] When it is necessary to adjust the diameter of the welding track of the main body 2 of the welding equipment to be adapted to the diameter of the circumferential weld, make the lifting column 6 move downward. The lifting column 6 gradually leaves the sliding groove 5. The lifting column 6 drives the first mounting frame 3 and the main body 2 of the welding equipment to move until the main body 2 of the welding equipment moves to a suitable position. Start the first motor 7 and the main body 2 of the welding equipment through the PLC. The first motor 7 drives the first gear 8 to rotate, making the first gear 8 walk on the annular rack 9, thereby driving the vertical shell 4 and the main body 2 of the welding equipment to rotate on the support 1, so that the main body 2 of the welding equipment can surround the circumferential weld for welding. The lifting column 6 slides in the sliding groove 5 to achieve stepless adjustment of the main body 2 of the welding equipment;

[0043] After the external support frame positions and clamps the steel pipe, start the second motor 12 through the PLC. The second motor 12 drives the second gear 13 to rotate. The second gear 13 drives the rotating ring plate 15 to rotate at one end of the U-shaped rod 14 through the arc-shaped rack 16. The rotating ring plate 15 drives a plurality of semi-circular blocks 22 to rotate. The semi-circular blocks 22 can press the semi-spherical balls 19 on the track. A plurality of semi-spherical balls 19 are simultaneously pressed towards the steel pipe. The semi-spherical balls 19 drive the pressure sensors 21 to move through the sliding rods 18, and the springs 20 are compressed, so that a plurality of pressure sensors 21 simultaneously abut against the outer wall of the steel pipe, keeping a plurality of pressure sensors 21 within a certain range. If the value of a certain pressure sensor 21 is not within this range, it means that the position of the steel pipe has shifted and needs to be corrected in time. Adjust the position states such as the height and angle of the steel pipe through the external support frame until the values of all pressure sensors 21 are within the specified range, thereby achieving the purpose of correcting the position of the steel pipe. Then, the first motor 7 and the main body 2 of the welding equipment can be started through the PLC for welding;

[0044] When the PLC starts the second motor 12 to detect the position of the steel pipe through the pressure sensor 21, the semi-sphere 19 will move towards the steel pipe. One of the semi-spheres 19 drives the vertical rod 29 to move towards the steel pipe through the jack 31 and the insertion rod 30. The vertical rod 29 drives the lifting column 6 to move towards the steel pipe through the telescopic sleeve 28, so that the lifting column 6 gradually slides out of the sliding groove 5, thereby achieving the purpose of adjusting the welding trajectory diameter of the welding equipment main body 2. After the adjustment is completed, the rotating block at one end of the threaded rod 23 is rotated to drive the threaded rod 23 to rotate. The threaded rod 23 drives the moving plate 24 to move. The moving plate 24 drives the abutting column 25 to be inserted into the avoidance hole 26 and abut against the side wall of the lifting column 6 to lock the lifting column 6. At the same time, the moving plate 24 can drive the vertical rod 29 and the insertion rod 30 to move through the telescopic plate 27, so that the insertion rod 30 leaves the jack 31, that is, the welding trajectory diameter of the welding equipment main body 2 is adjusted; the rotating block at one end of the threaded rod 23 can be replaced with a driving device, which is also controlled by the PLC;

[0045] During the welding process, the electric push rod 33 is started through the PLC. The electric push rod 33 drives the cleaning sleeve 34 to move towards the circumferential weld, so that the cleaning sleeve 34 contacts the circumferential weld and its vicinity. The vertical shell 4 rotates on the bracket 1 and can drive the electric push rod 33 and the cleaning sleeve 34 to rotate around the circumferential weld through the circular ring plate 32, so that the cleaning sleeve 34 can clean the slag and spatter attached to the circumferential weld and its vicinity;

[0046] There is liquid in the inner cavity 36 and the fixed sleeve 37. Starting the electric push rod 33 can drive the box body 35 and the cleaning sleeve 34 to move towards the circumferential weld, so that one end of the plurality of moving columns 38 abuts against the outer walls of the hollow ball and the steel pipe through the cleaning sleeve 34. Part of the moving columns 38 are first pressed into the fixed sleeve 37, so that the cleaning sleeve 34 deforms to fit the circumferential weld;

[0047] Before welding, the angle of the electromagnetic ultrasonic flaw detector 40 is adjusted through the adjusting mechanism on the second mounting bracket 39. During the cleaning process of the circumferential weld by the cleaning sleeve 34, the quality of the circumferential weld can be detected by the electromagnetic ultrasonic flaw detector 40;

[0048] When the electromagnetic ultrasonic flaw detector 40 detects a defect in a certain circumferential weld, the electromagnetic ultrasonic flaw detector 40 feeds back the information to the PLC. The PLC then activates the electromagnet 45. After the electromagnet 45 is energized, it generates a magnetic force that can attract the iron block 44. The iron block 44 can drive the sliding plate 42 and the marker pen 43 to move along the L-shaped chute 47, that is, first move upward and then move towards the electromagnet 45. The connecting rope 46 is stretched. When the marker pen 43 moves upward, it can contact the outer wall of the steel pipe. When the marker pen 43 moves towards the electromagnet 45, it can make a mark on the steel pipe, and the marked position is directly opposite the electromagnetic ultrasonic flaw detector 40, that is, directly opposite the defective position of the circumferential weld. After the marking is completed, the PLC turns off the electromagnet 45.
