Description

Technical Field

[0001] This invention relates to the field of steel production technology, and in particular to a metal detection device. Background Technology

[0002] Metal detectors are crucial inspection devices on long steel product production lines. Their signals are widely used in long product production, such as for position detection, length calculation, pinch roll movement, and rolling mill control. In the harsh environment of steel production, metal detectors are prone to malfunction and cannot perform normal inspections. Furthermore, unstable metal detector signals are a significant cause of production failures in long product manufacturing. A malfunctioning metal detector can halt normal production on the long product line, severely impacting production efficiency. Summary of the Invention

[0003] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a metal detection device to solve the problem that the failure of the metal detector in the prior art causes the long product production line to be unable to operate normally.

[0027] Please see Figure 1This embodiment provides a metal detection device, including a bracket 1, a first detection mechanism, and a second detection mechanism. The first detection mechanism includes a first support plate 21 and a first metal detector 22. The first support plate 21 is horizontally disposed on the side of the bracket 1, and the first metal detector 22 is disposed on the top right end of the first support plate 21. The second detection mechanism includes a second support plate 31 and a second metal detector 32. The second support plate 31 is horizontally disposed on the side of the bracket 1 and is located below the first support plate 21. The second metal detector 32 is disposed on the top right end of the second support plate 31. The bracket 1 increases the height of the first metal detector 22 and the second metal detector 32, reducing the environmental damage to the first metal detector 22 and the second metal detector 32 caused by direct placement on the steel production line. By using two metal detectors, the first metal detector 22 and the second metal detector 32, if one metal detector malfunctions, the other can still operate normally, avoiding any impact on the production of the steel production line.

[0028] In one implementation, such as Figure 1 As shown, the probes of the first metal detector 22 and the second metal detector 32 can both be adjusted in pitch and are secured by their respective pitch bolts.

[0029] In one implementation, such as Figure 1 As shown, a first reinforcing plate 23 is provided on the bracket 1. The two ends of the first reinforcing plate 23 are connected to the right side of the bracket 1 and the bottom of the first support plate 21, respectively. The right side of the bracket 1, the first reinforcing plate 23 and the bottom of the first support plate 21 form a triangular reinforcing structure, which can increase the stability of the first support plate 21.

[0030] In one implementation, such as Figure 1 As shown, a second reinforcing plate 33 is provided on the bracket 1. The two ends of the second reinforcing plate 33 are connected to the right side of the bracket 1 and the bottom of the second support plate 31, respectively. The right side of the bracket 1, the second reinforcing plate 33 and the bottom of the second support plate 31 form a triangular reinforcing structure, which can increase the stability of the second support plate 31.

[0031] In one implementation, such as Figure 1 As shown, a first mounting hole penetrating its thickness direction is provided on the top surface of the first support plate 21. The first metal detector 22 is mounted on the first support plate 21 through the first mounting hole, thereby increasing the fixing strength of the first metal detector 22 on the first support plate 21.

[0032] In one implementation, such as Figure 1As shown, a second mounting hole penetrating its thickness direction is provided on the top surface of the second support plate 31. The second metal detector 32 is mounted on the second support plate 31 through the second mounting hole, thereby increasing the fixing strength of the second metal detector 32 on the second support plate 31.

[0033] In one implementation, such as Figure 2 and Figure 3 As shown, the metal detection device also includes a calibration baffle 4, which is positioned opposite to the support 1, and the height of the calibration baffle 4 is greater than the height of the support 1. A rectangular calibration frame 41 is provided on the side of the calibration baffle 4 opposite to the support 1, that is, on the left side of the calibration baffle 4. The calibration frame 41 is used to calibrate the first metal detector 22 and the second metal detector 32.

[0034] In one embodiment, a first adjustment hole in the shape of an elongated strip is provided on the first support plate 21 along the left-right direction, and the first adjustment hole extends through the thickness direction of the first support plate 21. The bottom of the first metal detector 22 is slidably disposed in the first adjustment hole, so that the first metal detector 22 can slide left and right in the horizontal direction through the first adjustment hole, thereby allowing the first metal detector 22 to move closer to and further away from the calibration baffle 4 for horizontal calibration of the first metal detector 22.

[0035] In one embodiment, a long strip-shaped second adjustment hole is provided on the second support plate 31 along the left-right direction, and the second adjustment hole extends through the thickness direction of the second support plate 31. The bottom of the second metal detector 32 is slidably disposed in the second adjustment hole, so that the second metal detector 32 can slide left and right in the horizontal direction through the second adjustment hole, thereby allowing the second metal detector 32 to move closer to and further away from the calibration baffle 4 for horizontal calibration of the second metal detector 32.

[0036] In one implementation, such as Figure 4 As shown, the first metal detector 22 is provided with a first locking member 24, which is slidably disposed in the first adjustment hole in the horizontal direction. The first locking member 24 has a connecting end and a locking end. The top end is the connecting end, which is movably disposed at the bottom of the first metal detector 22 in the vertical direction. The bottom end is the locking end, which is disposed at the bottom of the first support plate 21. The first metal detector 22 can be locked by the first locking member 24. The first locking member 24 includes a bolt, and the top end of the first locking member 24 is threadedly connected to the first metal detector 22. When the first metal detector 22 needs to move horizontally, the first locking member 24 is loosened downwards; when the first metal detector 22 needs to be fixed, the first locking member 24 is tightened upwards.

[0037] In one embodiment, the second metal detector 32 is provided with a second locking member, which is slidably disposed within a second adjustment hole in a horizontal direction. The second locking member has a connecting end and a locking end. The top end is the connecting end, which is movably disposed at the bottom of the second metal detector 32 in a vertical direction. The bottom end is the locking end, which is disposed at the bottom of the second support plate 31. The second locking member can lock the second metal detector 32. The second locking member includes a bolt, and the top end of the second locking member is threadedly connected to the second metal detector 32. When the second metal detector 32 needs to move horizontally, the second locking member is loosened downwards; when the second metal detector 32 needs to be fixed, the second locking member is tightened upwards.

[0038] In one implementation, such as Figure 1 As shown, the bottom of bracket 1 is a trapezoid that is narrower at the top and wider at the bottom to improve the stability of bracket 1.

[0039] In one embodiment, a calibration method is also provided, comprising:

[0040] Turn on the first metal detector 31 and the second metal detector 32 and emit red light;

[0041] Adjust the distances between the first metal detector 31 and the second metal detector 32 and the calibration baffle 4 respectively, so that the red light emitted by the first metal detector 31 and the second metal detector 32 coincides with the calibration frame 41, and lock the first locking member 24 and the second locking member.

[0042] Place the test object above the calibration frame 41, and adjust the pitch screws of the first metal detector 31 and the second metal detector 32 respectively until the first metal detector 31 and the second metal detector 32 detect the signal of the test object.

[0043] Place the test object below the calibration frame 41, and adjust the pitch bolts of the first metal detector 31 and the second metal detector 32 respectively until the first metal detector 31 and the second metal detector 32 detect the signal of the test object. Finally, tighten the pitch bolts.

[0044] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention.
