Technical Field

[0002] In the steel coil production process, precise measurement of its dimensions is required. Currently, steel coil dimensions are measured manually and by instruments. Manual measurement involves workers visually measuring the diameter and width of the steel coil with a long ruler, which is inefficient and inaccurate. Instrument measurement involves placing infrared rangefinders on both sides of the steel coil's path. However, due to the harsh working environment, including high temperatures, dust, and water mist, the infrared rangefinders are often left stationary in these conditions, resulting in a high failure rate and impacting production progress and efficiency. Therefore, a measuring device is needed that can assist workers in efficiently measuring the width and diameter of steel coils. Utility Model Content

[0011] See Figure 1 and Figure 2 This utility model includes a measuring part, a docking part 1, and a display screen 2; there are two measuring parts, which are connected by the docking part 1; the two measuring parts cooperate to clamp the steel coil from both sides, thereby measuring the diameter and width of the steel coil; the display screen 2 is set on the docking part 1, and the signal input terminal of the display screen 2 is connected to the signal output terminal of the CPU; the display screen can display the real-time distance between the two pressure plates 3, and the diameter and width data of the steel coil can be obtained by clamping the steel coil in the diameter direction and width direction by the two pressure plates 3.
[0012] The measuring part includes a telescopic mechanism, a pull rope displacement sensor 11, and an alignment mechanism; one end of the telescopic mechanism is connected to the docking part 1, and the other end of the telescopic mechanism is connected to the alignment mechanism; the pull rope displacement sensor 11 is mounted on the telescopic mechanism, and the signal output terminal of the pull rope displacement sensor 11 is connected to the signal input terminal of the CPU.
[0013] The alignment mechanism includes a pressure plate 3, a sliding plate 4, a limiting plate 5, and a first connecting block 6. The pressure plate 3 has a first connecting block 6 at its center at one end. A square notch is provided at the end of the pressure plate 3 away from the first connecting block 6. The length direction of the square notch is parallel to the length direction of the pressure plate 3, and guide strips are provided along the length direction of the inner wall of the notch. Sliding grooves are provided at both ends of the sliding plate 4, and the sliding plate 4 slides between the guide strips on both sides of the inner wall of the notch via these grooves. The sliding plate 4 can slide between the two guide strips within the notch, allowing it to extend out of or detach from the notch. The thickness of the sliding plate 4 is the same as the thickness of the pressure plate 3, ensuring that the two end faces of the sliding plate 4 are aligned with the two end faces of the pressure plate 3. The limiting plate 5 is located on the end face of the pressure plate 3 near another measuring part, and the length direction of the limiting plate 5 is perpendicular to the length direction line of the pressure plate 3.
[0014] The telescopic mechanism includes a long rod 7, a sliding rod 8, a second connecting block 9, and a spring 10. The long rod 7 has a guide hole at its end, and the sliding rod 8 is inserted into the guide hole of the long rod 7. The sliding rod 8 can slide under the guidance of the guide hole of the long rod 7, thereby adjusting the length of the assembly of the sliding rod 8 and the long rod 7, ensuring that the pressure plate 3 at the end of the sliding rod 8 can smoothly press against the corresponding position of the steel coil. The end of the sliding rod 8 is connected to the pressure plate 3. The second connecting block 9 is disposed on the side wall of the long rod 7, and a spring 10 is connected between the first connecting block 6 and the second connecting block 9. The spring 10 provides force to the sliding rod 8, ensuring that the pressure plates 3 on both sides can reliably press against the side wall of the steel coil. The pull rope displacement sensor 11 is disposed on the side wall of the long rod 7 near the pressure plate 3, and the end of its pull rope is connected to the side wall of the pressure plate 3. The pull-string displacement sensor 11 can detect the distance between itself and the pressure plate 3. Since the distance between the pull-string displacement sensor 11 and the end of the long rod 7 is fixed and known, the distance detected by the pull-string displacement sensor 11 plus the distance between the pull-string displacement sensor 11 and the end of the long rod 7 is the distance between the end of the long rod 7 and the pressure plate 3. The sum of the distances between the ends of the long rod 7 and the pressure plate 3 of the two measuring parts is the distance between the two pressure plates 3. This distance is the real-time data displayed on the screen. When the two pressure plates 3 clamp the two outermost ends of the steel coil in the diameter direction, the data displayed on the screen is the diameter of the steel coil. When the two pressure plates 3 clamp the steel coil in the width direction, the data displayed on the screen is the width of the steel coil.
[0015] The connecting component 1 includes a first clamping plate and a second clamping plate; both ends of the first clamping plate and the second clamping plate are provided with through holes; the end of the long rod 7 away from the slide rod 8 is provided with a hole; the ends of the two long rods 7 away from the slide rod 8 are in contact with each other, and the two clamping plates clamp the contact parts of the two long rods 7. The through holes on the same side of the first clamping plate and the second clamping plate correspond to the holes of the long rods 7, and the bolt passes through the through hole of the first clamping plate, the hole of the long rod 7 and the through hole of the second clamping plate at the same time. The other end of the bolt is fixed by a nut; the display screen 2 is set on the first clamping plate; the cooperation of the first clamping plate and the second clamping plate enables the ends of the long rods 7 of the two measuring parts to be connected together to form a straight long rod.
[0016] The CPU module in this invention is model 87C196KC.
[0017] Operating principle: When the steel coil is in an upright position, that is, when the centerline of the steel coil is horizontal; the measurement steps are as follows; When measuring the diameter of a steel coil, manually pull the sliding rods 8 on both sides until the pressure plates 3 on both sides can clamp at the two ends of the steel coil in the diameter direction. Push the device forward so that both limiting plates press against the flat sidewall of the steel coil. The flat sidewall is the outer wall of the non-circular surface. Then move the device up and down slightly while observing the data on the display screen. Find the maximum value of the data, which is the diameter of the steel coil. When it is necessary to measure the width of the steel coil, manually pull the sliding rods 8 on both sides until the pressure plates 3 on both sides can clamp on both sides in the width direction of the steel coil. Then push the device forward so that both limiting plates press against the circumferential sidewall of the steel coil. The data on the display screen at this time is the width of the steel coil. When the steel coil is lying flat, that is, when the centerline of the steel coil is perpendicular, the measurement steps are as follows; The method for measuring the diameter is the same as the method described above. The steps for measuring the width of a steel coil lying flat are as follows: Remove the slide plate 4 from the first pressure plate 3. Press the removed pressure plate 3 onto the ground, ensuring it contacts the circumference of the steel coil. Press down on the first pressure plate 3 to prevent further movement. Then, pull the second pressure plate 3 upwards. When the second pressure plate 3 exceeds the height of the top of the steel coil, pull out the slide plate 4 of the second pressure plate 3, extending it halfway. Place the slide plate 4 removed from the first pressure plate 3 directly under the slide plate 4 of the second pressure plate 3, so that it presses against the top of the flattened steel coil. At this point, the display screen shows the width of the flattened steel coil. The extra slide plate 4 is used because the display shows the minimum distance between the two pressure plates 3, while the first... If the first pressure plate is pressed against the ground, and the second pressure plate is directly pressed against the other end of the steel coil, and the data on the display screen is less than the actual data by the thickness of one pressure plate, while the thickness of the sliding plate 4 is the same as the thickness of the pressure plate 3, then removing the sliding plate 4 of the first pressure plate 3 and placing it under the second pressure plate makes up for the difference. At this time, the data on the display screen is the actual width of the steel coil. Secondly, the reason for pulling out half of the sliding plate of the second pressure plate is that when the first pressure plate is on the ground, it can only contact the circumference of the steel coil, so the second pressure plate can only contact the circumference of the steel coil and cannot press against the flat side wall of the steel coil. Therefore, pulling out the sliding plate allows it to cross the circumference of the steel coil and press against the flat side wall of the steel coil.
