Description

Technical Field

[0001] This utility model relates to the field of steel strip technology, specifically a steel coil radius measuring device. Background Technology

[0002] In current production processes, steel strip production lines are demanding increasingly higher levels of automation and production efficiency. Rapid and stable coiling in the uncoiling area of ​​the strip production line directly impacts its efficient operation; therefore, coil diameter measurement and precise centering during coiling are critical processes.

[0003] To address the issue of inaccurate coil diameter measurement affecting subsequent centering and winding, the current production line solution is to accurately and efficiently measure the outer diameter of the steel coil before winding, ensuring successful centering and winding onto the uncoiler shaft in a single, fast, and efficient manner. Existing technology often measures the coil diameter on the transport trolley or saddle. However, if there are significant differences in coil diameter, the contact point between the coil and the trolley or saddle changes, compromising measurement accuracy and affecting the smooth operation of the winding process. Utility Model Content

[0004] The purpose of this invention is to provide a steel coil radius measuring device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel coil radius measuring device, including a base, and further comprising:

[0006] A support assembly for supporting a steel coil is mounted on a base. The steel coil body is placed on the support assembly. A bracket is mounted on one side of the support assembly. An installation assembly is mounted on the bracket. A laser rangefinder is mounted on the installation assembly.

[0007] Preferably, the support components are provided in two sets and are mirror-mounted on top of the base.

[0008] Preferably, the support assembly includes a roller rotatably mounted on a base, a servo motor is fixedly mounted on the base, and one end of the roller is fixedly connected to the output end of the servo motor.

[0009] Preferably, the mounting assembly includes a mounting housing fixedly mounted on a bracket, with fastening bolts threaded onto the mounting housing, and the laser rangefinder installed inside the mounting housing.

[0010] Preferably, the center of the straight line connecting the lens of the laser rangefinder and the center of the two idler rollers, as well as the center of the steel coil body, are on the same vertical straight line.

[0011] Preferably, a fixing seat is slidably mounted on the bottom of the base, and a groove is formed on the bottom of the base, in which the fixing seat is installed.

[0012] Preferably, limit strips are fixedly installed on both sides of the groove, and limit grooves are formed on both sides of the fixing seat, and the limit strips slide in the limit grooves.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention employs two sets of support components mirror-mounted on top of the base, using rollers to stably support the steel coil body. When the outer ring of the steel coil becomes loose, a servo motor is activated to drive the two rollers rotating in opposite directions, tightly wrapping the outer strip steel. This effectively avoids the problem of irregular shape affecting measurement accuracy due to the loose outer ring of the steel coil, providing a good foundation for precise measurement. The laser rangefinder is mounted on the bracket via mounting components, ensuring that the center of the laser rangefinder lens, the center of the line connecting the centers of the two rollers, and the center of the steel coil body are all on the same vertical line. This precise positioning and installation method guarantees the accuracy and reliability of the laser rangefinder's measurement data, allowing the measurement results to truly reflect the steel coil radius. This device can accurately and efficiently measure the outer diameter of the steel coil before winding, ensuring successful centering and winding onto the uncoiler shaft in one go. This avoids the need for multiple adjustments to the winding position due to inaccurate measurements, shortens winding time, and improves the overall operating efficiency of the production line.

[0020] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0021] Please see Figure 1-4As shown, a steel coil radius measuring device includes a base 1 and a support assembly 2 mounted on the base 1 to support the steel coil. A steel coil body 5 is placed on the support assembly 2 and is stably placed on the base 1 via the support assembly 2. A bracket 3 is mounted on one side of the support assembly 2, and an mounting assembly 6 is mounted on the bracket 3. A laser rangefinder 4 is mounted on the mounting assembly 6 and is mounted on the bracket 3 via the mounting assembly 6.

[0022] It should be noted that this device can accurately and efficiently measure the outer diameter of the steel coil before it is coiled, ensuring that the coil is successfully aligned and loaded onto the uncoiler shaft in one go. This avoids the need for multiple adjustments to the coiling position due to inaccurate measurements, shortens the coiling time, and improves the overall operating efficiency of the production line.

[0023] The support assembly 2 has two sets and is mirror-mounted on the top of the base 1. The support assembly 2 includes a roller 21 rotatably mounted on the base 1. A servo motor 22 is fixedly mounted on the base 1. One end of the roller 21 is fixedly connected to the output end of the servo motor 22. The servo motor 22 can drive the roller 21 to rotate on the base 1. The two rollers 21 rotate in opposite directions. When the outer ring of the steel coil body 5 is loose, the servo motor 22 can be started to drive the roller 21 to rotate, so as to tightly wrap the outer ring of the strip steel and ensure the accuracy of the outer diameter measurement.

[0024] Mounting assembly 6 includes a mounting housing 61 fixedly mounted on bracket 3. Fastening bolts 62 are threaded onto the mounting housing 61. A laser rangefinder 4 is mounted inside the mounting housing 61. The center of the line connecting the lens of the laser rangefinder 4 and the centers of the two idler rollers 21, as well as the center of the steel coil body 5, are on the same vertical line. The mounting housing 61 has a receiving groove to accommodate the laser rangefinder 4. After placing the laser rangefinder 4 into the mounting housing 61, tightening the fastening bolts 62 secures the laser rangefinder 4 inside the mounting housing 61. The laser head of the laser rangefinder 4 is vertically downwards. Figure 4 As shown, the distance between the laser rangefinder 4 and the top of the steel coil body 5 is H1, the distance between the laser rangefinder 4 and the top of the base 1 is H2, the distance between the centers of the two idler rollers 21 is C, the radius of the steel coil body 5 is R, the radius of the idler rollers 21 is r, and the center point of the steel coil body, the center point of the idler rollers 21, and the midpoint of the line connecting the two idler rollers 21 form a right triangle. According to the Pythagorean theorem, we can derive the formula: (R+r) 2 =H 2 +(C / 2) 2 As shown in the diagram, H = H2 - H1. The radius of the steel coil can then be calculated. -r.

[0025] A fixed seat 7 is slidably installed on the bottom of the base 1. A groove 8 is opened on the bottom of the base 1, and the fixed seat 7 is installed in the groove 8. Limiting strips 9 are fixedly installed on both sides of the groove 8. Limiting grooves 10 are opened on both sides of the fixed seat 7, and the limiting strips 9 slide in the limiting grooves 10. The base 1 can move freely on the fixed seat 7. After the distance measurement is completed, the steel coil can be moved to the designated position to facilitate subsequent processing by the uncoiler. When the base 1 moves, it drives the limiting strips 9 to slide in the limiting grooves 10, which can improve the stability of the base 1, thereby improving the stability of the steel coil body 5 when it moves.

[0026] Working principle: The steel coil body 5 is placed on the support components 2, which are mirror images mounted on the top of the base 1. The rollers 21 of the support components 2 support the steel coil body 5, making it stable on the base 1. When the outer ring of the steel coil body 5 becomes loose, the servo motor 22, which is fixedly connected to one end of the roller 21 on the base 1, is started to drive the roller 21 to rotate. The two rollers 21 rotate in opposite directions, tightly wrapping the outer ring of the strip steel to ensure the accuracy of the outer diameter measurement. The laser rangefinder 4 is mounted on the bracket 3 through the mounting component 6. During installation, it is ensured that the center of the straight line connecting the lens of the laser rangefinder 4 and the center of the two rollers 21, as well as the center of the steel coil body 5, are on the same vertical straight line. After placing the laser rangefinder 4 into the receiving slot of the mounting housing 61, tighten the fastening bolts 62 to fix it in place, with the laser head of the laser rangefinder 4 pointing vertically downwards. Measure the distance H1 between the measuring head of the laser rangefinder 4 and the top of the steel coil body 5, and the distance H2 between the laser rangefinder 4 and the top of the base 1. Given that the distance between the centers of the two idler rollers 21 is C, the radius of the steel coil body 5 is R, and the radius of the idler rollers 21 is r, and based on the fact that the center point of the steel coil body, the center point of the idler rollers 21, and the midpoint of the line connecting the two idler rollers 21 form a right triangle, the formula can be derived using the Pythagorean theorem: (R + r) 2 =H 2 +(C / 2) 2 The formula is used to calculate the radius R of the steel coil, where H = H2 - H1.
