[0013] A pair of rectangular notches penetrating two semicircular grooves are respectively provided on both sides of the steel drum positioning body, and the two flip arms can respectively move through the two rectangular notches on the semicircular grooves; when the belts on the two flip arms pass through the rectangular notches and are parallel to each other, they can contact the side wall of the steel drum on the steel drum rotating disk; the diameter of the sprocket three is smaller than the diameter of the sprocket two, and the chain two mounted on the two does not exceed the side where the belt contacts the steel drum.

[0014] The present invention is further configured as follows: the rotating assembly includes a transmission shaft horizontally rotatably arranged on a conveying frame and located between two rotating shafts four, a worm gear reduction motor two fixedly mounted on the conveying frame and fixed by the transmission shaft through the output end, a pair of bevel gears one respectively fixedly mounted on both ends of the transmission shaft and symmetrical to each other, and a pair of bevel gears two respectively fixed on two rotating shafts four and respectively meshing with the two bevel gears one, and the transmission shaft, the worm gear reduction motor two, the bevel gear one and the bevel gear two are all located below the roller conveyor.

[0015] The present invention is further configured as follows: a plurality of holes are evenly opened on the inner wall of the semicircular groove of the steel drum positioning body, positioning rollers are rotatably arranged in the holes, and the positioning rollers in each of the holes evenly roll and contact the outer wall of the steel drum on the steel drum rotating disk.

[0016] The beneficial effects of the present invention are:

[0017] By adopting the above technical solution, before the last step of the lid closing process in the production of steel drums, the steel drums that need to be inspected for internal quality will first enter a steel drum conveyor line of this system, and then the steel drum conveyor line will convey the steel drums toward the cabinet. At the same time, a steel drum rotating disk on the rotating platform is facing the end of the steel drum conveyor line, waiting for the steel drum to approach;

[0018] When the steel drum is about to reach the end of the rolling conveyor in the steel drum conveying line, the rotating assembly in the steel drum transfer device will immediately drive the two rotating shafts four to rotate synchronously and in opposite directions, so that the flip arms at the top of the two rotating shafts four flip in the direction of passing through the rectangular notch of the steel drum positioning body, and until the belts of the two flip arms completely pass through the two rectangular notches and contact the outer wall of the steel drum in parallel with each other;

[0019] Then, the small motors on the two flip arms will synchronously and reversely drive the sprockets 2 connected to their respective output ends to rotate, so that the sprockets 2 drive the sprockets 3 to rotate through the chain 2. Since the sprockets 3 are fixedly connected to a pulley on which the belt is set, the pulleys on the two flip arms will respectively drive the two belts to synchronously transport the steel drums when the sprockets 3 on the two flip arms rotate synchronously in the opposite direction, so that the steel drums leave the rolling conveyor and are accurately positioned on a steel drum rotating disk on the rotating platform under the positioning of the semicircular arc groove on the steel drum positioning body.

[0020] Then the rotating assembly drives the rotating shaft 4 to rotate in the opposite direction again, so that the flip arm returns to the initial position, and at the same time, the lifting device drives the two steel drum internal detection devices to rise and fall synchronously and in opposite directions, so that the steel drum internal detection device located above the steel drum extends into the interior of the steel drum, and the other steel drum internal detection device is raised to a high position to prepare for subsequent steel drum detection work;

[0021] After that, the servo motor in the rotating device will start to drive the worm meshing transmission worm wheel to rotate, and the rotating shaft 1 connected to the worm wheel will rotate with it, and thereby drive the rotating platform to rotate relative to the cabinet, so that the steel barrel rotating disk loaded with steel barrels on the rotating platform rotates and moves to the beginning of another steel barrel conveyor line; at the same time, since the small gear connected to the rotating shaft 2 at the bottom of the steel barrel rotating disk meshes with the large gear fixed on the top of the cabinet, during the rotation of the above-mentioned rotating platform, the small gear will rotate and mesh around the large gear, and thereby drive the steel barrel rotating disk to rotate relative to the rotating platform, and because the steel barrel internal detection device has previously extended into the inner wall of the steel barrel, during the process of the steel barrel rotating disk driving the steel barrel to rotate relative to the rotating platform, the detection camera and fill light in the above-mentioned steel barrel internal detection device will relatively detect along the inner wall of the steel barrel for one circle, thereby achieving a quick and efficient steel barrel inner wall detection effect;

[0022] Finally, if the computing control device connected to the steel barrel inspection device obtains a good inspection result of the internal quality of the steel barrel, the steel barrel will be rotated by the rotating platform to the beginning of the steel barrel conveyor line that outputs the steel barrel to the steel barrel capping station. At the same time, the steel barrel transfer device on the steel barrel conveyor line will, together with the working steps of the previous steel barrel transfer device, take the steel barrel from the steel barrel rotating disk and send it to the roller conveyor in the steel barrel conveyor line, and then transport the steel barrel to the capping process at the rear.

[0023] If the above equipment detects defects inside the steel barrel, the steel barrel will be rotated by the rotating platform to the beginning of the steel barrel conveyor line that outputs the steel barrel to the steel barrel maintenance station. At the same time, the steel barrel transfer device on the steel barrel conveyor line will, together with the previous working steps of the steel barrel transfer device, take the steel barrel from the steel barrel rotating disk and send it to the roller conveyor in the steel barrel conveyor line, and then transport the steel barrel to the maintenance station at the rear for inspection and rework.

[0024] Among them, when the above-mentioned steel barrel inspection is completed (the inspection result is good) and is about to leave the steel barrel rotating disk, the steel barrel conveyor line that inputs the steel barrel into the steel barrel rotating disk will roll the next steel barrel on the conveyor, and cooperate with the steel barrel picking and delivering device on it to send the steel barrel to another steel barrel rotating disk on the rotating platform. At the same time, the lifting device drives the two steel barrel internal inspection devices to lift and lower in opposite directions again, so that one steel barrel internal inspection device leaves the inspected steel barrel and rises to a high place so that the inspected steel barrel can be taken away, while the other steel barrel internal inspection device is extended into the steel barrel to be inspected, and the above-mentioned steel barrel inspection steps are repeated again (the rotating platform in this step rotates in the opposite direction to prevent the electrical circuits from being entangled), thereby realizing continuous and efficient automatic steel barrel inspection work.

[0035] Semicircular grooves 41 are symmetrically provided on both sides of the steel barrel positioning body 4, the steel barrel rotating disk 5 and the semicircular groove 41 are coaxial, and the outer contour of the steel barrel rotating disk 5 is close to the inner wall of the semicircular groove 41; a steel barrel conveyor line 9 cooperates with the steel barrel picking-up and delivery device 10 thereon to input steel barrels to a steel barrel rotating disk 5 on the rotating platform 2, and the other two steel barrel conveyor lines 9 respectively cooperate with the steel barrel picking-up and delivery device 10 thereon to take out the steel barrels on the other steel barrel rotating disk 5, and transport them to the steel barrel maintenance station and the steel barrel capping station respectively; the steel barrel conveyor line 9 for inputting steel barrels to the steel barrel rotating disk 5 and the steel barrel conveyor line 9 for outputting steel barrels to the steel barrel capping station are symmetrically located on both sides of the cabinet 1; the steel barrel conveyor line 9 includes a conveyor frame 91 and a roller conveyor 92 installed on the conveyor frame 91.

[0036] like Figure 2 As shown, the rotating device 3 includes a rotating shaft 31 fixed to the bottom of the rotating platform 2 and rotatingly passing through the interior of the cabinet 1, a worm wheel 32 fixedly mounted on the rotating shaft 31, a worm 33 rotatably arranged in the cabinet 1 and meshing with the worm wheel 32, and a servo motor 34 whose output end is connected to the worm 33 and drives the worm 33 to rotate. The servo motor 34 is fixed to the outer wall of the cabinet 1, and one end of the worm 33 rotates out of the outer wall of the cabinet 1 and is fixedly connected to the output end of the servo motor 34. By adopting the above rotating device 3, not only can the rotating platform 2 be stably driven to rotate, but also the self-locking function of the worm wheel 32 and the worm 33 can lock the fixed rotating platform 2 before and after the rotating platform 2 rotates, thereby ensuring that the steel barrel rotating disk 5 thereon stably and safely receives or delivers steel barrels.

[0037] like Figure 2As shown, the rotating device 2 6 includes a pair of rotating shafts 2 61 respectively fixed to the bottom of the two steel drum rotating disks 5 and rotating through the rotating platform 2, a pair of small gears 62 respectively fixed on the two rotating shafts 2 61 and located below the rotating platform 2, and a large gear 63 fixed to the middle of the top of the cabinet 1 and meshing with the two small gears 62 at the same time. The large gear 63 is located between the bottom of the rotating platform 2 and the top of the cabinet 1, and the rotating shaft 1 31 rotates through the axis of the large gear 63. The two small gears 62 are located on both sides of the large gear 63 and mesh with the large gear 63 while rotating and moving around the large gear 63. By adopting the above-mentioned rotating device 2 6, not only can the rotation of the rotating platform 2 be converted into the rotation of the steel drum rotating disk 5, but also the transmission ratio of the large gear 63 and the small gear 62 can expand the small rotation of the rotating platform 2 into the large rotation of the steel drum rotating disk 5, and then cooperate with the steel drum internal detection device 7 to fully and effectively detect the internal quality of the steel drum.

[0038] like Figure 1 , Figure 3 As shown, the lifting device 8 includes a gate-shaped bracket 81 fixed to the middle of the top of the steel drum positioning body 4, a pair of rotating shafts 82 parallel to each other and rotatably arranged in the middle of the gate-shaped bracket 81, a worm gear reduction motor 83 driving the rotating shaft 82 to rotate, two pairs of sprockets 84 respectively fixedly installed on the two rotating shafts 82, two chains 85 respectively sleeved on the two pairs of sprockets, a pair of lifting rods 86 parallel to each other and fixedly connected to the two chains 85, and a pair of lifting rods 86 parallel to each other and fixedly connected to the two chains 85. A lifting rod 2 87 is connected to two chains 1 85, and lifting rod 1 86 and lifting rod 2 87 are respectively located on both sides of sprocket 1 84, and are respectively close to the top of the gate-shaped bracket 81 and the top of the steel drum positioning body 4, the steel drum internal detection device 7 is fixedly set on the two lifting rods 1 86 or the two lifting rods 2 87, the worm gear reduction motor 1 83 is fixedly installed on the outer wall of the gate-shaped bracket 81, and one end of the rotating shaft 3 82 rotates through the outer wall of the gate-shaped bracket 81 and is fixedly connected to the output end of the worm gear reduction motor 1 83.

[0039] By adopting the above-mentioned lifting device 8, when it is necessary to drive the two steel barrel internal detection devices 7 to lift, first the worm gear reduction motor 83 will drive the rotating shaft 3 82 to rotate, and then the two sprockets 84 on the rotating shaft 3 82 will rotate with it, and in the process of rotation, drive two chains 85 to transport the lifting rod 1 86 and the lifting rod 2 87 up and down respectively. Since the lifting rod 1 86 and the lifting rod 2 87 are respectively located on both sides of the sprocket 1 84, the lifting rod 1 86 and the lifting rod 2 87 will respectively drive the two steel barrel internal detection devices 7 to lift and lower in different directions, thereby achieving the effect that one steel barrel internal detection device 7 descends and extends into the interior of the steel barrel to be inspected, and the other steel barrel internal detection device 7 rises and leaves the interior of the steel barrel after the inspection.

[0040] like Figure 1 , Figure 3 As shown, the steel drum internal detection device 7 includes a connecting rod 71 horizontally fixedly connected to one end of two lifting rods 1 86 or two lifting rods 2 87, a pair of suspension rods 72 vertically fixed to the bottom of the connecting rod 71, a limit end plate 73 fixedly connected to the lower ends of the two suspension rods 72, a lifting slide 74 slidably connected to the two suspension rods 72, an adjustment component 75 for adjusting and controlling the height of the lifting slide 74 relative to the limit end plate 73, a pair of connecting rods 1 76 respectively hingedly connected to the two ends of the lifting slide 74 at one end, and a pair of limit end plates respectively hingedly connected to the limit end plates at one end. There are connecting rods 77 at both ends of 73, two vertically symmetrical detection long plates 78 which are hinged to the other ends of two pairs of connecting rods 1 76 and 77 respectively, a plurality of detection cameras 781 evenly fixed on one side of the detection long plate 78 up and down, and a plurality of fill-in lights 782 evenly fixed on one side of the detection long plate 78 up and down and staggered on each detection camera 781, the detection cameras 781 and the fill-in lights 782 are located on the side of the detection long plate 78 which is away from the suspension rod 72, and the connecting rods 1 76 and 77 are of equal length and symmetrical with each other up and down.

[0041] By adopting the above-mentioned steel barrel internal detection device 7, when the steel barrel internal detection device 7 descends and extends into the steel barrel, the two detection long plates 78 will be parallel to the inner wall of the steel barrel, and the detection camera 781 and the fill light 782 on one side of the detection long plate 78 will be turned on at the same time, which can not only cooperate with the rotation of the steel barrel rotating disk 5 to realize rapid detection of the inner wall of the steel barrel, but also the detection cameras 781 evenly distributed on one side of the detection long plate 78 can fully scan various positions of the inner wall of the steel barrel, so as to obtain accurate detection results. Among them, when the adjustment component 75 is used to control the distance between the lifting slide 74 and the limiting end plate 73, since the detection long plate 78 lifts the lifting slide 74 and the limiting end plate 73 respectively, they are hingedly connected to the connecting rod 1 76 and the connecting rod 2 77, and the connecting rod 1 76 and the connecting rod 2 77 are symmetrical with each other up and down. Therefore, in the process of the lifting slide 74 moving away from and approaching the limiting end plate 73, the connecting rod 1 76 and the connecting rod 2 77 will flip relative to each other, and push or pull the detection long plate 78 away from or close to the inner wall of the steel barrel, thereby adjusting the distance between the detection long plate 78 and the inner wall of the steel barrel to adapt to the detection work inside steel barrels with different inner diameters.

[0042] like Figure 3 , Figure 4As shown, the adjustment assembly 75 includes a square groove 751 opened on the top of the lifting slide 74, a pair of right-angled trapezoidal sliders 752 that are symmetrical to each other and slide horizontally in the square groove 751, an isosceles trapezoidal slider 753 that slides vertically in the square groove 751 and is inverted between the two right-angled trapezoidal sliders 752, a square end cover 754 fixedly covered on the square groove 751, a locking screw 755 that vertically passes through the square end cover 754 and has its lower end pressed on the top of the isosceles trapezoidal slider 753, and a screw threaded connection 754 that is fixed to the top of the square end cover 754. The locking nut 756 is connected to the locking screw 755, and the two suspension rods 72 slide through the square groove 751 and the square end cover 754. The isosceles trapezoidal slider 753 and the two right-angled trapezoidal sliders 752 are located between the two suspension rods 72, and the slopes of the two right-angled trapezoidal sliders 752 are respectively in parallel with the slopes on both sides of the isosceles trapezoidal slider 753. The right-angled trapezoidal slider 752 is provided with an arc notch 752a on the side facing away from the isosceles trapezoidal slider 753 that can closely contact the surface of the suspension rod 72. The head of the locking nut 756 is fixedly connected to a flat knob 755a.

[0043] When the distance between the lifting slide plate 74 and the limit end needs to be adjusted by adopting the above-mentioned adjustment component 75, the straight-shaped knob 755a is first manually turned to screw out the locking screw 755 threadedly connected to the locking nut 756 on the square cover upward; since the isosceles trapezoidal slider 753 is pressed down by the lower end of the locking screw 755, and the slopes of the two right-angled trapezoidal sliders 752 are respectively in parallel with the slopes on both sides of the isosceles trapezoidal slider 753, during the process of the locking nut 756 withdrawing upward from the square groove 751, the isosceles trapezoidal slider 753 will gradually loosen the two right-angled trapezoidal sliders 752 and contact them closely with the two suspension rods 72 The pressure is reduced, and the static friction between the right-angled trapezoidal slider 752 and the suspension rod 72 is reduced in this way. At this time, the staff can easily manually lift the lifting slide 74 to adjust the distance between the lifting slide 74 and the limit end plate 73; finally, after the lifting slide 74 reaches the appropriate height, the straight-shaped knob 755a is reversed again to screw the locking screw 755 into the square groove 751, and the isosceles trapezoidal slider 753 is pressed down, and the two right-angled trapezoidal sliders 752 will be in close contact with the suspension rod 72 again under the pressure of the isosceles trapezoidal slider 753, that is, the sliding of the lifting slide 74 on the suspension rod 72 is locked again. Among them, the arc notch 752a can increase the contact surface between the right-angled trapezoidal slider 752 and the suspension rod 72, thereby improving the friction between the right-angled trapezoidal slider 752 and the suspension rod 72 to a certain extent.

[0044] like Figure 5 , Figure 6As shown, the steel barrel transfer device 10 includes a pair of rotating shafts 101 vertically rotatably arranged on both sides of the conveyor frame 91, a rotating assembly 102 driving the two rotating shafts 101 to rotate synchronously and in opposite directions, a pair of flip arms 103 each having one end fixedly connected to the top of the two rotating shafts 101, two pairs of pulleys 104 rotatably arranged on one side of the two flip arms 103, two belts 105 respectively sleeved on the two pairs of pulleys 104, a small motor 106 fixedly installed on the other side of the flip arm 103, a sprocket 107 fixedly installed on the output end of the small motor 106, and a pulley 103 fixedly installed on the output end of the pulley 103. 4 ends, and the chain 2 109 sleeved on the sprocket 1 84 and the sprocket 3 108; a pair of rectangular notches 42 penetrating the two semi-circular arc grooves 41 are respectively provided on both sides of the steel barrel positioning body 4, and the two flip arms 103 can respectively move through the two rectangular notches 42 on the semi-circular arc grooves 41; when the belts 105 on the two flip arms 103 pass through the rectangular notches 42 and are parallel to each other, they can contact the side wall of the steel barrel on the steel barrel rotating disk 5; the diameter of the sprocket 3 108 is smaller than the diameter of the sprocket 2 107, and the chain 2 109 sleeved on the two does not exceed the side of the belt 105 contacting the steel barrel. By adopting the above steel barrel conveying device 10, not only can the effect of conveying the steel barrel in and out of the steel barrel rotating disk 5 be effectively achieved, but also the position of the steel barrel can be positioned on the roller conveyor 92 to ensure that the steel barrel accurately falls on the steel barrel rotating disk 5 on the rotating platform 2.

[0045] like Figure 6 As shown, the rotating assembly 102 includes a transmission shaft 102a which is horizontally rotatably arranged on the conveying frame 91 and located between the two rotating shafts 4 101, a worm gear reduction motor 2 102b which is fixedly mounted on the conveying frame 91 and fixed by the transmission shaft 102a through the output end, a pair of bevel gears 1 102c which are respectively fixedly mounted on both ends of the transmission shaft 102a and are symmetrical to each other, and a pair of bevel gears 2 102d which are respectively fixed on the two rotating shafts 4 101 and respectively mesh with the two bevel gears 1 102c. The transmission shaft 102a, the worm gear reduction motor 2 102b, the bevel gear 1 102c and the bevel gear 2 102d are all located below the roller conveyor 92. When it is necessary to drive the two transmission shafts 102a to rotate, first the worm gear reduction motor 102b will drive the transmission shaft 102a to rotate, and then the two bevel gears 102c on the transmission shaft 102a will respectively mesh with and transmit the two bevel gears 102d. Since the two bevel gears 102c are symmetrically installed on the transmission shaft 102a, the two bevel gears 102c will respectively drive the two rotating shafts 101 to rotate in opposite directions under the meshing transmission of the two bevel gears 102c, thereby achieving the effect of controlling the relative flipping of the two flip arms 103.

[0046] like Figure 2As shown, the steel drum positioning body 4 is evenly provided with a plurality of holes 43 on the inner wall of the semicircular groove 41, and positioning rollers 44 are rotatably arranged in the holes 43, and the positioning rollers 44 in each hole 43 evenly roll and contact the outer wall of the steel drum on the steel drum rotating disk 5. By adopting the above holes 43 and positioning rollers 44, not only can the position of the steel drum on the steel drum rotating disk 5 be positioned, but also the friction between the inner wall of the semicircular groove 41 and the steel drum can be prevented, so as to ensure the safe rotation of the steel drum.

[0047] The working principle of this embodiment:

[0048] Before the last step of the steel barrel production process, the steel barrel that needs to be inspected for internal quality will first enter a steel barrel conveyor line 9 of this system, and then the steel barrel conveyor line 9 will convey the steel barrel toward the cabinet 1. At the same time, a steel barrel rotating disk 5 on the rotating platform 2 is facing the end of the steel barrel conveyor line 9, waiting for the steel barrel to approach;

[0049] When the steel drum is about to reach the end of the rolling conveyor in the steel drum conveying line 9, the rotating assembly 102 in the steel drum conveying device 10 will immediately drive the two rotating shafts 4 101 to rotate synchronously and in opposite directions, so that the flipping arms 103 on the top of the two rotating shafts 4 101 flip in the direction of passing through the rectangular notch 42 of the steel drum positioning body 4, respectively, until the belts 105 of the two flipping arms 103 completely pass through the two rectangular notches 42 and contact the outer wall of the steel drum in parallel with each other;

[0050] Then, the small motors 106 on the two flip arms 103 will synchronously and reversely drive the sprocket 2 107 connected to their respective output ends to rotate, so that the sprocket 2 107 drives the sprocket 3 108 to rotate through the chain 2 109. Since the sprocket 3 108 is fixedly connected to a pulley 104 on which the belt 105 is sleeved, the pulleys 104 on the two flip arms 103 will respectively drive the two belts 105 to synchronously transport the steel barrel when the sprocket 3 108 on the two flip arms 103 rotate synchronously and reversely, so that the steel barrel leaves the rolling conveyor and is accurately positioned on a steel barrel rotating disk 5 on the rotating platform 2 under the positioning of the semicircular arc groove 41 on the steel barrel positioning body 4.

[0051] Then the rotating assembly 102 drives the rotating shaft 101 to rotate in the opposite direction again, so that the flip arm 103 returns to the initial position, and at the same time the lifting device 8 drives the two steel drum internal detection devices 7 to rise and fall synchronously and in opposite directions, so that the steel drum internal detection device 7 located above the steel drum extends into the interior of the steel drum, and the other steel drum internal detection device 7 is raised to a high position to prepare for subsequent steel drum detection work;

[0052] After that, the servo motor 34 in the rotating device will start to drive the worm 33 to mesh with the worm wheel 32 to rotate, and the rotating shaft 1 31 connected to the worm wheel 32 will rotate with it, and thereby drive the rotating platform 2 to rotate relative to the cabinet 1, so that the steel barrel rotating disk 5 loaded with steel barrels on the rotating platform 2 rotates and moves to the beginning of another steel barrel conveyor line 9; at the same time, since the small gear 62 connected to the rotating shaft 2 61 at the bottom of the steel barrel rotating disk 5 meshes with the large gear 63 fixed on the top of the cabinet 1, during the rotation of the above-mentioned rotating platform 2, the small gear 62 will rotate and mesh around the large gear 63, and thereby drive the steel barrel rotating disk 5 to rotate relative to the rotating platform 2, and because the steel barrel internal detection device 7 has previously extended into the inner wall of the steel barrel, during the steel barrel rotating disk 5 drives the steel barrel to rotate relative to the rotating platform 2, the detection camera 781 and the fill light 782 in the above-mentioned steel barrel internal detection device 7 will relatively detect along the inner wall of the steel barrel for one circle, thereby achieving a quick and efficient steel barrel inner wall detection effect;

[0053] Finally, the computing control device connected to the steel barrel inspection device, if the inspection result of the internal quality of the steel barrel is good, the steel barrel will be rotated by the rotating platform 2 to the beginning of the steel barrel conveyor line 9 that outputs the steel barrel to the steel barrel capping station. At the same time, the steel barrel pick-up and delivery device 10 on the steel barrel conveyor line 9 will, together with the previous working steps of the steel barrel pick-up and delivery device 10, take the steel barrel from the steel barrel rotating disk 5 and send it to the roller conveyor 92 in the steel barrel conveyor line 9, and then transport the steel barrel to the capping process at the rear.

[0054] If the above-mentioned equipment obtains the detection result that there are defects inside the steel barrel, the steel barrel will be rotated by the rotating platform 2 to the beginning of the steel barrel conveyor line 9 that outputs the steel barrel to the steel barrel maintenance station. At the same time, the steel barrel picking-up and delivery device 10 on the steel barrel conveyor line 9 will, together with the previous working steps of the steel barrel picking-up and delivery device 10, pick up the steel barrel from the steel barrel rotating disk 5, and send it to the roller conveyor 92 in the steel barrel conveyor line 9, and then transport the steel barrel to the rear maintenance station for inspection and rework.

[0055] Among them, when the above-mentioned steel barrel inspection is completed (the inspection result is good) and is about to leave the steel barrel rotating disk 5, the steel barrel is input to the steel barrel conveyor line 9 on the steel barrel rotating disk 5, and the next steel barrel on the rolling conveyor will be cooperated with the steel barrel picking and delivering device 10 thereon to send the steel barrel to another steel barrel rotating disk 5 on the rotating platform 2. At the same time, the lifting device 8 drives the two steel barrel internal inspection devices 7 to lift and lower in opposite directions again, so that one steel barrel internal inspection device 7 leaves the inspected steel barrel and rises to a high place so that the inspected steel barrel can be taken away, while the other steel barrel internal inspection device 7 is extended into the steel barrel to be inspected, and the above-mentioned steel barrel inspection steps are repeated again (the rotating platform 2 in this step rotates in the opposite direction to prevent the electrical circuits from being entangled), thereby realizing continuous and efficient automatic steel barrel inspection work.
