AI Technical Summary
Existing metal sheet flaw detectors require prior knowledge of the width of the steel sheet to be inspected, and the measuring grating is easily contaminated, leading to false detections, which increases costs and maintenance difficulty.
Design a width measuring mechanism for steel plate flaw detection. By setting a detection blank area on the sensor integrated beam, the detection is limited to the range of the minimum width steel plate. A visible light sensor and a signal relay switch box are used. The sensor is 50cm above the roller conveyor to avoid false detection and reduce sensor installation and maintenance costs.
This enables accurate measurement without prior knowledge of the steel plate width, reducing sensor installation and maintenance costs and improving sensor stability and contamination resistance.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel plate measurement technology, and in particular to a width measuring mechanism for steel plate flaw detection. Background Technology
[0002] Currently, in order to ensure that the coverage size of the detection probe matches the width of the steel plate, the width of the steel plate to be inspected needs to be known in advance to avoid the working probe falling too little or too much, thus failing to meet the actual inspection requirements.
[0003] Most existing flaw detectors typically have a through-beam measuring grating installed before the flaw detector entrance to detect the width of the steel plate. However, the cost of using the measuring grating is relatively high, and part of the through-beam grating is located below the roller conveyor, which is easily covered by sewage, sludge, dust, etc., causing false detections.
[0004] Based on this, this utility model proposes a width measuring mechanism for steel plate flaw detection. Utility Model Content
[0005] To address the aforementioned technical issues, this utility model provides a width measuring mechanism for steel plate flaw detection. By setting a detection blank area, it limits the detection to the range of the minimum width steel plate, saving the need for sensors in the detection blank area and reducing the installation and maintenance costs of sensors when measuring the width of steel plate flaw detection.
[0006] The width measuring mechanism for steel plate flaw detection in this solution includes a steel plate conveying roller and a sensor integrated beam disposed above it. The sensor integrated beam is perpendicular to the conveying direction of the steel plate conveying roller and includes a detection blank area and a detection area. Multiple sensors are arranged along the length of the detection area on the sensor integrated beam. The detection blank area is located between the steel plate conveying edge line and the minimum steel plate width edge line. The steel plate conveying edge line is flush with one side edge line of the steel plate conveying roller's width during steel plate conveying in the vertical direction, and the minimum steel plate width edge line is flush with the other side edge line of the steel plate conveying roller's width during steel plate conveying in the vertical direction.
[0007] The further defined technical solution of this utility model is:
[0008] Furthermore, it also includes cable trays connected to the sensor integration beam, with the sensors arranged at equal intervals within the cable trays.
[0009] Furthermore, it also includes a sensor signal relay switch box connected to one end of the sensor integration beam, and the sensor is connected to the sensor signal relay switch box via a cable.
[0010] Furthermore, the sensor includes a visible light sensor.
[0011] Furthermore, the sensor integrated beam has columns connected to both ends.
[0012] Furthermore, the height of the sensor is at least 50cm higher than the conveying surface of the steel plate conveying roller.
[0013] The beneficial effects of this utility model are: the width measuring mechanism for steel plate flaw detection of this utility model limits the detection blank area to the range of the minimum width steel plate by setting the detection blank area, which saves the sensor for the detection blank area and reduces the installation and maintenance cost of the sensor when measuring the width of steel plate flaw detection; in addition, the upper-mounted sensor arrangement of this mechanism is more stable and is not easily contaminated by water stains or other contaminants, which may cause false detection.

[0018] The width measuring mechanism for steel plate flaw detection provided in this embodiment is as follows: Figure 1 , Figure 2 As shown, this system is applied at the inlet 7 of the flaw detector and specifically includes a steel plate conveying roller conveyor 6 and a sensor integrated beam 1 mounted above it. The sensor integrated beam 1 is perpendicular to the conveying direction of the steel plate conveying roller conveyor 6, with vertical columns connected to both ends. The sensor integrated beam 1 includes a detection blank area 5 and a detection area. Multiple sensors 4 are evenly distributed along the length of the detection area of the sensor integrated beam 1, while the detection blank area 5 is located between the steel plate conveying edge line 8 and the minimum steel plate width edge line 9. Specifically, the steel plate conveying edge line 8 is flush with one side edge line of the steel plate conveying roller conveyor 6 in the vertical direction along the steel plate width direction, and the minimum steel plate width edge line 9 is flush with the other side edge line of the steel plate conveying roller conveyor 6 in the vertical direction along the steel plate width direction. A cable trough 3 is installed on the sensor integrated beam 1, and the sensors 4 can be evenly arranged and installed in the cable trough 3.
[0019] In this embodiment, sensor 4 is specifically a visible light sensor. A sensor signal relay switch box 2 is installed at one end of the sensor integrated beam 1, and each sensor 4 is connected to the sensor signal relay switch box 2 through the cable in the cable groove 3.
[0020] like Figure 3 As shown, the height of sensor 4 is at least 50cm higher than the conveying surface of steel plate conveying roller 6, so that the steel plates on steel plate conveying roller 6 are not affected during conveying.
[0021] Specifically, see Figure 2 The sensor integrated beam 1 of the width measuring mechanism for steel plate flaw detection in this application is divided into steel plate conveying edge line 8, minimum steel plate width edge 9, and maximum steel plate width edge 10, combined with... Figure 1 It can be seen that the steel plate conveying edge line 8 is flush with the width edge line on one side of the steel plate, the minimum steel plate width edge 9 is flush with the width edge line on the other side of the minimum steel plate, and the maximum steel plate width edge 10 is flush with the width edge line on the other side of the maximum steel plate. That is, the steel plate conveying edge line 8 is fixed, and the position of the width edge on the other side of the steel plate varies according to the width specification of the steel plate. In this application, the detection blank area 5 is limited to the range of the minimum width steel plate. The width of the steel plate can be determined by the distance from the steel plate conveying edge line 8 to the farthest sensor 4 that can detect the steel plate. Therefore, the sensor 4 in the detection blank area 5 does not need to be installed, saving a lot of installation and maintenance costs.
[0022] In addition to the above embodiments, this utility model may have other implementation methods; all technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
