Description

Technical Field

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

[0002] Straightness is an important indicator of strip shape quality. The quality of strip straightness directly affects the quality of strip products. During the production process of flattening or cross-cutting the strip, it is usually necessary to measure the strip multiple times to timely understand the strip shape quality under the current production parameters and provide a reference for the adjustment of subsequent production parameters.

[0003] In the related art, the leveling and cross-cutting production lines usually use an aluminum alloy square straight rod in combination with a tapered ruler to measure the plate shape, that is, the aluminum alloy square straight rod is manually placed on the surface of the strip, and the largest gap between the square straight rod and the strip is visually checked to find the point, the tapered ruler is inserted into the gap and the feeler gauge value is read, thereby realizing the measurement of the strip shape defects; however, the measurement method of the above-mentioned measuring tool is complicated, and manual operation is required to perform multi-point measurements on the same section of the strip separately. Its measurement efficiency is low, the measurement accuracy is poor, and the labor intensity is high, which cannot meet the high-efficiency measurement requirements of the leveling and cross-cutting production lines for the strip. Utility Model Content

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

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

[0006] An automatic measuring device for strip shape based on contact ranging includes a gantry, which spans across both ends of the strip conveying roller.

[0007] Cross beams are provided on both sides of the gantry frame in the length direction, and longitudinal beams are provided on both sides of the gantry frame 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] Support beams are respectively provided between the corresponding groups of slides on both sides, and a driving device is provided in the middle of the support beams;

[0010] A second slide rail is provided at the bottom of the support beam so as to be liftable. A slider is provided on the second slide rail so as to be slidable. A displacement sensor is provided on one side of the slider.

[0011] The automatic strip shape measuring device based on contact ranging according to this solution has at least the following technical effects:

[0012] This contact ranging-based automatic strip shape measuring device uses a slide table that slides on a first slide rail and drives a support beam to move along the length direction of the beam. According to the width of the strip, the slide tables at the two ends are moved above the corresponding position of the strip edge. The second slide rail is lowered by a driving device so that the bottom of the second slide rail contacts the surface of the strip. The pull rod displacement sensor is compressed, and the compression amount of the pull rod displacement sensor can be obtained. The slider slides on the second slide rail, driving the pull rod displacement sensor to move along the length direction of the strip, and the compression amount of different positions of the strip can be measured.

[0013] When the strip has a flatness defect, the gap between the bottom of the second slide rail and different positions along the strip length will be different, and the compression amount of the pull rod displacement sensor when it moves along the strip length will also be different. This can measure the pull rod distance at different positions of the strip.

[0014] The device slides on the first slide rail through the slide table, which can adapt to strips of different widths and can efficiently measure the flatness of the strip at different positions. The time for each measurement point does not exceed 2s, which can greatly improve the measurement accuracy and efficiency of the strip flatness. The parameters of the strip flatness can be adjusted according to the measurement results, which is beneficial to improving the quality of the strip flatness and meeting the high-efficiency measurement requirements of the flattening and cross-cutting production lines for strips.

[0015] As a further solution of the present invention: the driving device is a stepping motor, and a rotating shaft is provided at one end of the stepping motor.

[0016] As a further solution of the present invention: it also includes a traction rope, the two ends of the traction rope are respectively connected to the two ends of the second slide rail, and the middle part of the traction rope is wound around the rotating shaft.

[0017] Since the driving device is a stepper motor, a rotating shaft is provided at one end of the stepper motor, and it also includes a traction rope. The two ends of the traction rope are respectively connected to the two ends of the second slide rail, and the middle part of the traction rope is wrapped around the rotating shaft through part of the forward direction and part of the reverse direction, so that the driving device drives the rotating shaft to rotate, and drives the traction ropes at both ends of the second slide rail to rise and fall at the same time, realizing the rise and fall of the second slide rail, thereby driving the pull rod displacement sensor to contact the surface of the strip steel, and through the compression amount of the pull rod displacement sensor, the surface flatness of the strip steel is quickly measured, thereby improving the measurement accuracy and efficiency of the strip steel plate shape.

[0018] As a further solution of the present invention: the middle group of slides is fixed.

[0019] 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.

[0020] As a further solution of the present invention: plugs are respectively provided at both ends of the first slide rails on both sides.

[0021] 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.

[0022] As a further solution of the present invention: a roller is provided at the bottom of the pull rod displacement sensor.

[0023] Since a roller is provided at the bottom of the pull rod displacement sensor, the bottom of the pull rod displacement sensor contacts the surface of the strip through the roller. When the slider slides on the second slide rail and drives the pull rod displacement sensor to move, it can prevent the bottom of the pull rod displacement sensor from rubbing against the surface of the strip and causing damage to the surface of the strip. It can also reduce the sliding resistance of the slider on the second slide rail when the bottom of the pull rod displacement sensor contacts the surface of the strip, thereby improving operational flexibility and measurement efficiency.

[0024] As a further solution of the present invention: an electromagnet is provided at the bottom of the second slide rail.

[0025] Since an electromagnet is provided at the bottom of the second slide rail, when the second slide rail descends to the surface of the strip, the electromagnet is energized, so that the bottom of the second slide rail and the surface of the strip generate an adsorption force, so that during the movement of the pull rod displacement sensor, the second slide rail can be effectively prevented from swinging or shaking, which affects the measurement accuracy. At the same time, the shaking of the second slide rail can be prevented from affecting the compression of the pull rod displacement sensor, thereby ensuring the stability of the second slide rail and improving the measurement accuracy of the flatness of the strip surface.

[0037] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for the purpose of explaining the present invention and are not intended to limit the present invention. 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.

[0038] 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 are within the scope of protection of the present invention.

[0039] like Figure 1-4 The embodiment of the utility model shown is an automatic measuring device for strip plate shape based on contact ranging, comprising a gantry 1, which spans across both ends of the strip conveyor rollers, with cross beams 101 provided on both sides along the length direction of the gantry 1, and longitudinal beams 102 provided on both sides along the width direction of the gantry 1; the cross beams 101 on both sides are respectively provided with first slide rails 103, and a number of groups of slides 104 are respectively provided on the first slide rails 103 on both sides; support beams 105 are respectively provided between the corresponding groups of slides 104 on both sides, and a driving device 106 is provided in the middle of the support beam 105; a second slide rail 107 is provided at the bottom of the support beam 105 in a liftable manner, a slider 108 is slidably provided on the second slide rail 107, and a pull rod displacement sensor 109 is provided on one side of the slider 108.

[0040] During use, the slide 104 slides on the first slide rail 103 and drives the support beam 105 to move along the length direction of the crossbeam 101. According to the width of the strip, the slides 104 at the two ends are moved to above the corresponding positions of the strip edge. The second slide rail 107 is lowered by the driving device 106 so that the bottom of the second slide rail 107 contacts the surface of the strip, so that the pull rod displacement sensor 109 is compressed, and the compression amount of the pull rod displacement sensor 109 can be obtained. Moreover, the slider 108 slides on the second slide rail 107, driving the pull rod displacement sensor 109 to move along the length direction of the strip, and the compression amount of different positions of the strip can be measured.

[0041] When the strip has a flatness defect, the gap between different positions in the length direction of the strip and the bottom of the second slide rail 107 is different, and the compression amount of the pull rod displacement sensor 109 when moving along the length direction of the strip is also different, thereby measuring the pull rod distance at different positions of the strip.

[0042] Specifically, the device can adapt to strips of different widths by sliding the slide 104 on the first slide rail 103, and can efficiently measure the flatness of the strip at different positions. The time for each measurement point does not exceed 2s, which can greatly improve the measurement accuracy and efficiency of the strip shape. The parameters of the strip flatness are adjusted according to the measurement results, which is beneficial to improving the quality of the strip shape and meeting the high-efficiency measurement requirements of the flatness and cross-cutting production lines for the strip.

[0043] like Figure 1 and Figure 3 As shown, the driving device 106 is a stepper motor, and a rotating shaft 110 is provided at one end of the stepper motor; it also includes a traction rope 111, the two ends of the traction rope 111 are respectively connected to the two ends of the second slide rail 107, and the middle part of the traction rope 111 is wrapped around the rotating shaft 110.

[0044] Specifically, since the driving device 106 is a stepper motor, a rotating shaft 110 is provided at one end of the stepper motor, and it also includes a traction rope 111. The two ends of the traction rope 111 are respectively connected to the two ends of the second slide rail 107. The middle part of the traction rope 111 is wrapped around the rotating shaft 110 through part of the forward direction and part of the reverse direction, so that the driving device 106 drives the rotating shaft 110 to rotate, and drives the traction ropes 111 at both ends of the second slide rail 107 to rise and fall at the same time, realizing the rise and fall of the second slide rail 107, thereby driving the pull rod displacement sensor 109 to contact the surface of the strip. Through the compression amount of the pull rod displacement sensor 109, the surface flatness of the strip is quickly measured, thereby improving the measurement accuracy and efficiency of the strip plate shape.

[0045] Furthermore, the middle group of slides 104 is fixed.

[0046] 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.

[0047] like Figure 1 and Figure 2 As shown, plugs 112 are respectively provided at both ends of the first slide rails 103 on both sides.

[0048] Specifically, by providing plugs 112 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.

[0049] like Figure 4 As shown, a roller 113 is provided at the bottom of the pull rod displacement sensor 109 .

[0050] Specifically, since a roller 113 is provided at the bottom of the pull rod displacement sensor 109, the bottom of the pull rod displacement sensor 109 contacts the surface of the strip through the roller 113. When the slider 108 slides on the second slide rail 107 and drives the pull rod displacement sensor 109 to move, it can prevent the bottom of the pull rod displacement sensor 109 from rubbing against the surface of the strip and causing damage to the surface of the strip, and can reduce the sliding resistance of the slider 108 on the second slide rail 107 when the bottom of the pull rod displacement sensor 109 contacts the surface of the strip, thereby improving operational flexibility and measurement efficiency.

[0051] In another embodiment of the present invention, an electromagnet is provided at the bottom of the second slide rail 107 .

[0052] Specifically, since an electromagnet is provided at the bottom of the second slide rail 107, when the second slide rail 107 descends to the surface of the strip, the electromagnet is energized, so that the bottom of the second slide rail 107 and the surface of the strip generate an adsorption force, so that during the movement of the pull rod displacement sensor 109, the second slide rail 107 can be effectively prevented from swinging or shaking, which affects the measurement accuracy. At the same time, the shaking of the second slide rail 107 can be prevented from affecting the compression of the pull rod displacement sensor 109, thereby ensuring the stability of the second slide rail 107 and improving the measurement accuracy of the flatness of the strip surface.

[0053] 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. As long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should all fall within the scope of protection of the present utility model.
