Description

Technical Field

[0001] The utility model relates to the technical field of strip steel flatness measurement, in particular to an automatic strip steel flatness measurement device based on laser ranging. Background Art

[0002] Straightness is an important indicator of strip flatness quality, and its quality directly affects the quality of the strip products. In the actual production of the metallurgical and machinery manufacturing industries, in many cases it is necessary to measure the straightness of the strip when it is out of tension or at rest. For this flatness measurement scenario, the only way to measure it currently is manually using a level and a wedge ruler. The measurement efficiency and accuracy cannot meet the requirements of efficient and high-quality production.

[0003] In the related technologies, the currently mature strip flatness measuring devices include contact flatness meters and non-contact flatness meters. The contact flatness meter obtains the strip flatness information by detecting internal stress, and has high detection accuracy. However, this device has high requirements on the surface quality of the strip, and the strip must have a certain tension. It is mostly used in cold rolling production lines with better on-site production environments. The non-contact flatness meter obtains the strip flatness information by detecting the relative height difference of the strip, and can only measure the straightness of the moving strip. The two strip flatness measuring devices have poor versatility and applicability, and cannot meet the measurement requirements of the strip surface straightness when it is out of tension or stationary. Utility Model Content

[0004] The purpose of the present utility model is to provide an automatic measuring device for strip flatness based on laser ranging, so as to solve at least one aspect of the problems and defects raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] An automatic measuring device for the flatness of a steel strip based on laser ranging comprises a gantry support, the gantry support spanning across both ends of a steel strip conveying roller,

[0007] Cross beams are provided on both sides of the gantry support in the length direction, and longitudinal beams are provided on both sides of the gantry support in the width direction;

[0008] The crossbeams on both sides are respectively provided with first slide rails, and the first slide rails on both sides are respectively provided with a plurality of sets of slide platforms;

[0009] Second slide rails are respectively arranged between the corresponding groups of slide platforms on both sides, and a slider is arranged on the second slide rail. A laser rangefinder is arranged on one side of the slider.

[0010] The automatic measuring device for strip flatness based on laser ranging according to this solution has at least the following technical effects:

[0011] The automatic measuring device for the flatness of the steel strip based on laser ranging is arranged at both ends of the steel strip conveying roller. First slide rails are respectively arranged on the cross beams on both sides of the gantry support. Several groups of slide platforms are respectively arranged on the first slide rails on both sides. Second slide rails are respectively arranged between the several groups of slide platforms on both sides. Slide blocks are arranged on the second slide rails. A laser rangefinder is arranged on one side of the slide block. The automatic measuring device can measure the flatness of multiple different positions in the width direction and length direction of the steel strip through the laser rangefinder.

[0012] By driving several groups of slides to slide on the first slide rail through the driving device, the second slide rail can be driven to move along the length direction of the gantry bracket, so that the measuring range of the device can be adaptively adjusted according to the different positions and widths of the strip. At the same time, the slider can slide along the length direction of the second slide rail, so that measurement can be performed along the length direction of the strip, thereby improving the versatility and accuracy of measuring the plate shape of strips of different sizes. In addition, the device can meet the measurement requirements of the flatness of the strip when it is out of tension or stationary, effectively improving the reliability and efficiency of the strip shape measurement, and making targeted parameter adjustments to the flatness of the strip to ensure the production quality of the strip.

[0013] A further solution of the utility model is that the light source of the laser rangefinder is perpendicular to the strip conveying roller.

[0014] Since the light source of the laser rangefinder is perpendicular to the strip conveyor roller, the light source of the laser rangefinder can be perpendicular to the strip surface. By sliding the slide in the first slide rail and the slider in the second slide rail, the distance from different positions on the strip surface to the laser rangefinder can be measured, thereby measuring the flatness value of different positions on the strip plate surface. Vertical measurement of the strip flatness can ensure measurement accuracy, avoid measurement errors caused by oblique measurement, and improve measurement stability and reliability.

[0015] A further solution of the utility model is that the middle group of slides is fixed.

[0016] Since the middle group of slides is fixed, the middle group of slides is used as the measurement basis for the flatness of the strip shape. The slides on both sides of the middle slide can be adaptively adjusted according to different measurement positions or width dimensions of the strip, ensuring the consistency and accuracy of the entire measurement process and improving the adaptability and efficiency of strip flatness measurement.

[0017] A further solution of the utility model is that plugs are respectively provided at both ends of the first slide rails on both sides.

[0018] By setting plugs at both ends of the first slide rails on both sides, the slides at both ends of the first slide rail can be effectively prevented from sliding out of the first slide rail, thereby preventing the slide from falling and causing equipment damage or measurement interruption, ensuring the correct operation of the slide on the first slide rail, and effectively improving the operational safety of the device.

[0019] A further solution of the utility model: the measuring range of the laser rangefinder is 0.02m-2m.

[0020] Since the measuring range of the laser rangefinder is 0.02m-2m, it is suitable for measuring the flatness of industrial products such as strip steel within this size range. It achieves high measurement accuracy, can meet the industrial demand for high precision, and effectively improve the production quality of strip steel.

[0021] A further solution of the utility model: the repeatability of the laser rangefinder is ±0.5 mm.

[0022] Since the laser rangefinder has a repeatability accuracy of ±0.5mm, it can ensure the consistency and comparability of each measurement result of the strip flatness, so that multiple measurements performed under the same conditions can provide reliable data, increase the confidence in the measurement results, reduce random errors in the measurement process, and improve the overall accuracy of the data, which has a positive impact on improving production efficiency, quality control and customer satisfaction.

That is, the embodiments described herein are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and illustrated in the drawings herein can be arranged and designed in a variety of different configurations.

[0034] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work shall fall within the scope of protection of the present invention.

[0035] like Figure 1-3The embodiment of the utility model shown is an automatic measuring device for the straightness of a strip steel based on laser ranging, comprising a gantry support 1, the gantry support 1 spanning across both ends of a strip steel conveying roller, cross beams 101 being provided on both sides along the length direction of the gantry support 1, and longitudinal beams 102 being provided on both sides along the width direction of the gantry support 1; first slide rails 103 are provided on the cross beams 101 on both sides, and a number of groups of slides 104 are provided on the first slide rails 103 on both sides respectively; second slide rails 105 are provided between the corresponding groups of slides 104 on both sides, a slider 106 is provided on the second slide rail 105, and a laser rangefinder 107 is provided on one side of the slider 106.

[0036] Specifically, the automatic measuring device for the flatness of the strip steel based on laser ranging is arranged at both ends of the strip steel conveying roller, and first slide rails 103 are respectively arranged on the cross beams 101 on both sides of the gantry support 1, and a plurality of groups of slide platforms 104 are respectively arranged on the first slide rails 103 on both sides, and second slide rails 105 are respectively arranged between the plurality of groups of slide platforms 104 on both sides, and a slider 106 is arranged on the second slide rail 105. A laser rangefinder 107 is arranged on one side of the slider 106, so that the automatic measuring device can measure the flatness of multiple different positions in the width direction and the length direction of the strip steel through the laser rangefinder 107;

[0037] By driving a plurality of groups of slides 104 to slide on the first slide rail 103 through a driving device, the second slide rail 105 can be driven to move along the length direction of the gantry bracket 1, so that the measuring range of the device can be adaptively adjusted according to the different positions and widths of the strip. At the same time, the slider 106 can slide along the length direction of the second slide rail 105, so that measurement can be performed along the length direction of the strip, thereby improving the versatility and accuracy of measuring the plate shape of strips of different sizes; in addition, the device can meet the measurement requirements of the flatness of the strip when it is out of tension or stationary, effectively improving the reliability and efficiency of the strip shape measurement, and making targeted parameter adjustments to the flatness of the strip to ensure the production quality of the strip.

[0038] Furthermore, the light source of the laser rangefinder 107 is perpendicular to the strip conveying roller.

[0039] Specifically, since the light source of the laser rangefinder 107 is perpendicular to the strip conveyor roller, the light source of the laser rangefinder 107 can be perpendicular to the surface of the strip. By sliding the slide 104 in the first slide rail 103 and the slider 106 in the second slide rail 105, the distance from different positions on the strip surface to the laser rangefinder 107 can be measured, thereby measuring the flatness value of different positions on the strip plate surface. Vertically measuring the flatness of the strip can ensure measurement accuracy, avoid measurement errors caused by oblique measurement, and improve the stability and reliability of the measurement.

[0040] Furthermore, the middle group of slides 104 is fixed.

[0041] Specifically, since the middle group of slides 104 is fixed, the middle group of slides 104 is used as the measurement basis for the flatness of the strip shape. The slides on both sides of the middle slide 104 can be adaptively adjusted according to different measurement positions of the strip or the width of the strip, ensuring the consistency and accuracy of the entire measurement process and improving the adaptability and efficiency of the strip flatness measurement.

[0042] like Figure 1 and Figure 2 As shown, plugs 108 are respectively provided at both ends of the first slide rails 103 on both sides.

[0043] Specifically, by providing plugs 108 at both ends of the first slide rails 103 on both sides, the slides 104 at both ends of the first slide rails 103 can be effectively prevented from sliding out of the first slide rails 103, thereby preventing the slides 104 from falling and causing equipment damage or measurement interruption, ensuring that the slides 104 run correctly on the first slide rails 103, and effectively improving the operational safety of the device.

[0044] According to an embodiment of the present invention, the measurement range of the laser rangefinder 107 is 0.02m-2m.

[0045] Specifically, since the measurement range of the laser rangefinder 107 is 0.02m-2m, it is suitable for measuring the flatness of industrial products such as strip steel within this size range, achieving higher measurement accuracy, meeting the industrial demand for high precision, and effectively improving the production quality of strip steel.

[0046] It should also be noted that the repeatability of the laser rangefinder 107 is ±0.5 mm.

[0047] Specifically, since the repeatability of the laser rangefinder 107 is ±0.5 mm, the consistency and comparability of each measurement result of the strip flatness can be ensured, so that multiple measurements under the same conditions can provide reliable data, which increases the confidence in the measurement results, reduces random errors in the measurement process, and improves the overall accuracy of the data, which has a positive impact on improving production efficiency, quality control and customer satisfaction.

[0048] The above content is merely an example and explanation of the structure of the present utility model. Technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner.
