DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] Embodiment 1:

The telescopic rod 34 can be a telescopic cylinder, an electric telescopic rod, etc.

[0021] During operation, the cooled and formed copper rod enters along the tube body 11, and after being transported out from the discharge end of the tube body 11, the telescopic rod 34 extends, and the upper pressure wheel body 31 moves downward, so that the copper rod continues to be transported backward under the support between the upper pressure wheel body 31 and the first guide wheel 21. After the copper rod passes through the flaw detector 4 for flaw detection, it is guided by the third guide wheel 23 and transported to the next process; when there is no copper rod to be detected, the telescopic rod 34 is in a retracted state, and the upper pressure wheel body 31 rises; when there is a copper rod to be detected, the telescopic rod 34 is in an extended state, and the upper pressure wheel body 31 is in a descending state, so as to realize the support and transportation of the copper rod, so that the copper rod can basically maintain a relatively stable height when passing through the flaw detector 4 for flaw detection, thereby reducing the detection error caused by the shaking of the copper rod and improving the flaw detection effect.

[0022] Preferably, along the conveying direction of the copper rod, the diameter of the tube body 11 gradually decreases; and the height of the discharge end of the tube body 11 is adapted to the height of the first guide wheel 21 .

[0023] Embodiment 2:

[0024] like Figure 1-Figure 2 As shown, with respect to the above embodiments, this embodiment optimizes the height adjustment structure.

[0025] The heights of the tube body 11, the first guide wheel 21, the third guide wheel 23 and the flaw detector 4 in the copper rod online automatic flaw detection device are all adjustable, so that adaptive adjustment can be made according to the diameter of the copper rod, thereby improving the application scope of the device.

[0026] The limiting tube 1 includes a tube body 11, a first connecting plate 12, a first base 13, a first waist-shaped hole 14 and a first connecting bolt 15. The first waist-shaped hole 14 for cooperating with each other is set on the first base 13 and the first connecting plate 12. The first base 13 and the first connecting plate 12 are fastened together by the first connecting bolt 15, and the height of the tube body 11 can be adjusted by the waist-shaped hole and the connecting bolt.

The first fixing rod 212 is fixedly arranged in the vertical direction, and the second waist-shaped hole 213 is arranged on the first fixing rod 212 in the vertical direction. The position height between the guide wheel body 211 and the first fixing rod 212 is adjusted by the second waist-shaped hole 213 and the connecting bolts.

[0028] The flaw detector 4 includes a flaw detection ring body 41, a third connecting rod 42, and a third fixed rod 43. The third fixed rod 43 is fixedly arranged in the vertical direction. The position height is adjusted between the third connecting rod 42 and the third fixed rod 43 through a third waist-shaped hole 421 and a connecting bolt. The flaw detection ring body 41 is fixedly arranged on the top of the third connecting rod 42.

[0029] Embodiment 3:

[0030] like Figure 1-Figure 2 As shown, for the above embodiments, this embodiment optimizes the automatic detection control.

[0031] In the present copper rod online automatic flaw detection device, a first sensor 61 is provided at the discharge end of the first guide wheel 21, and the first sensor 61 is electrically connected to the signal input end of the PLC controller 5; the telescopic rod 34 is electrically connected to the output control end of the PLC controller 5. The first sensor 61 can be a capacitive position proximity switch, which is used to detect whether there is a copper rod and transmit the signal to the PLC controller 5 for receiving and processing. When the copper rod is detected, the PLC controller 5 controls the telescopic rod 34 to be in an extended state at all times, and when the copper rod is detected, the PLC controller 5 controls the telescopic rod 34 to be in a retracted state, so as to realize automatic control of the support of the upper pressing wheel according to the copper rod.

[0032] Embodiment 4:

[0033] like Figure 1-Figure 2 As shown, for the above embodiments, this embodiment optimizes the detection mark structure.

[0034] In the present copper rod online automatic flaw detection device, a first meter-counting speed meter 71 is arranged at the feeding end of the flaw detector 4, and a spray gun 8 is arranged at the discharging end of the flaw detector 4. The first meter-counting speed meter 71 is electrically connected to the signal input end of the PLC controller 5, and the spray gun 8 is electrically connected to the output control end of the PLC controller 5. The first meter-counting speed meter 71 is used to detect the traveling speed of the copper rod and transmit it to the PLC controller 5 for receiving and processing. When the flaw detector detects that there is damage on the copper rod, the meter-counting speed meter and the PLC controller automatically calculate and determine the location of the damage, and control the spray gun 8 to spray marks at both ends of the damage in real time, which is convenient for the operator to cut the damage at a later stage, thereby improving the efficiency of the flaw detection operation.

[0035] Embodiment 5:

[0036] like Figure 1-Figure 2 As shown, for the above embodiments, this embodiment optimizes the detection mark structure.

[0037] In the present copper rod online automatic flaw detection device, a second meter-counting speed meter 72 is arranged between the discharge end of the flaw detector 4 and the spray gun 8, and the second meter-counting speed meter 72 is electrically connected to the signal input end of the PLC controller 5. After the tail of the copper rod leaves the first confidential speed meter 71, the travel speed of the copper rod cannot be detected. Therefore, the travel speed of the copper rod is detected and fed back by the second meter-counting speed meter 72, which is more accurate, can reduce marking errors, and save production costs.

[0038] And by the first meter-counting speedometer 71 and the second meter-counting speedometer 72 working together, the travel speed of the copper rod can be calibrated and compared in real time to improve the accuracy of measurement; at the same time, when the copper rod collides with the flaw detection ring 41, that is, when the data difference between the two groups of meter-counting speedometers is large, the PLC controller 5 will give an alarm indication, prompting the operating personnel to handle the abnormality in time to avoid a larger safety accident.

[0039] Embodiment 6:

[0040] like Figure 1-Figure 2 As shown, for the above embodiments, this embodiment optimizes the detection mark structure.

[0041] In the present copper rod online automatic flaw detection device, a second sensor 62 is arranged between the feed end of the flaw detector 4 and the first meter-counting speedometer 71, and the second sensor 62 is electrically connected to the signal input end of the PLC controller 5. On the basis of Example 5, when the second sensor 62 does not detect the copper rod, the PLC controller 5 takes the measurement data of the second meter-counting speedometer 72 as the standard; when the second sensor 62 detects the presence of the copper rod, the PLC controller 5 calculates and outputs after calibration with the data of the two sets of meter-counting speedometers; when the second sensor 62 detects the presence of the copper rod, and the detection data of the two sets of meter-counting speedometers are too small (or zero), it is judged that an abnormality occurs in the subsequent work section, and the PLC controller 5 promptly controls the shutdown of the relevant facilities to avoid causing a major safety accident, thereby improving the safety of the use of the present device.
