[0033] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0034] In related technologies, there is a lack of roll gap inspection instruments for offline repair of MCCR (Mid-thickness Controlled Cooling and Rolling) sector sections. The only option is to rely on traditional inside micrometers for repeated measurements and calibrations. This approach is not only time-consuming and labor-intensive, but also inconvenient in reading measurement data, severely impacting production efficiency and measurement accuracy. Due to the lack of automated and precise inspection methods, workers need to invest significant time and effort in manual operation, which not only increases labor intensity but may also lead to measurement errors due to human factors, thus affecting the quality control of the entire production process.

[0035] Based on the above considerations, this application proposes a continuous casting machine roller opening degree detection device, which has a simple structure and is easy to operate. It can efficiently and accurately measure the gap between rollers, improve production efficiency, and ensure the stability and reliability of product quality.

[0036] The following is for reference. Figures 1-3 This application describes a continuous casting machine roller opening degree detection device according to an embodiment of the present application.

[0037] Please see Figure 1 and Figure 2 The continuous casting machine roller 2 opening degree detection device provided in this application embodiment includes a measuring rod 11, a first measuring head 12, a measuring instrument 15, a lever mechanism and a positioning bracket 18.

[0038] The measuring rod 11 is hollow.

[0039] The measuring rod 11 can be made of a hollow stainless steel tube to ensure its strength and durability while reducing the overall weight. Its internal space is sufficient to accommodate the first measuring head 12, lever mechanism, and other components.

[0040] The first measuring head 12 is installed inside the measuring rod 11 and can move along the measuring rod 11 between an extended position and a retracted position. When the first measuring head 12 is in the extended position, at least a portion of the first measuring head 12 extends beyond the first end of the measuring rod 11.

[0041] The first measuring head 12 can be cylindrical, square, or rhomboid in shape. It is made of a wear-resistant metal material, such as tungsten steel or high-manganese steel. During measurement, the first measuring head 12 frequently contacts and rubs against the surface of the roller 2. By selecting wear-resistant materials to improve its durability and reduce wear, it can maintain good shape and dimensional accuracy even after prolonged use, thereby improving measurement accuracy. One end of the first measuring head 12 can be mounted inside the measuring rod 11 via a sliding pair. During measurement, through external driving force or the action of an internal spring, the first measuring head 12 can move smoothly between the extended and retracted positions along the axis of the measuring rod 11.

[0042] When the first measuring head 12 is in the extended position, the front end of the first measuring head 12 extends beyond the first end of the measuring rod 11 and contacts the surface of the roller 2. When in the retracted position, the first measuring head 12 is completely retracted into the measuring rod 11. This is equivalent to reaching the limit of the first measuring head 12's movement, that is, the length of the measuring rod 11 extended when the first measuring head 12 is in the extended position, which determines the maximum adjustable range of the device.

[0043] The measuring instrument 15 is installed on the side of the measuring rod 11; the lever mechanism is located inside the measuring rod 11, the active end of the lever mechanism is connected to the first measuring head 12, and the driven end of the lever mechanism is connected to the measuring end of the measuring instrument 15.

[0044] The measuring instrument 15 can be a digital display measuring instrument 15, which facilitates the measurement of degrees. Specifically, the measuring instrument 15 can be a high-precision electronic measuring instrument 15, such as a displacement sensor or laser rangefinder, which is fixed to the side of the measuring rod 11 by screws or clips. Its measuring end is connected to the driven end of the lever mechanism through an internal transmission line or wireless transmission module, enabling real-time and accurate acquisition of measurement data. The measuring instrument 15 can also be a mechanically triggered measuring instrument 15, such as a mechanical dial indicator or mechanical micrometer. When a mechanical dial indicator or mechanical micrometer is selected, it is connected to the driven end of the lever mechanism through a precise mechanical structure, converting the displacement transmitted by the lever mechanism into numerical values, thereby intuitively displaying the measurement results.

[0045] The lever mechanism can be made of high-strength alloy material. Exemplarily, the lever mechanism may include a lever body, a connecting shaft, and a rotating pair. The driving end of the lever mechanism is connected to the first measuring head 12 via a pin, hinge, or ball joint, while the driven end is connected to the measuring end of the measuring instrument 15 via a transmission component, such as a rack and pinion drive, a lead screw and nut drive, or a connecting rod drive. When the first measuring head 12 moves, it drives the driving end of the lever mechanism to move. Through the amplification or reduction effect of the lever, the displacement is accurately transmitted to the driven end and then detected by the measuring instrument 15.

[0046] The positioning bracket 18 is sleeved on the outside of the measuring rod 11. The positioning bracket 18 has two sets of positioning wheels 182 distributed on both sides of the measuring rod 11 on the side facing the second end of the measuring rod 11. The two sets of positioning wheels 182 are used to roll in contact with the surface of the roller 2 so that the measuring rod 11 is perpendicular to the axis of the roller 2.

[0047] The positioning bracket 18 can be made of robust aluminum alloy or cast iron and is installed on the outside of the measuring rod 11 via a sleeve, snap-fit, or threaded connection. On the side of the positioning bracket 18 facing the second end of the measuring rod 11, two sets of positioning wheels 182 are mounted on both sides of the measuring rod 11 via pins, bolts, or welding. The positioning wheels 182 can be made of rubber, nylon, or polyurethane, with a certain degree of surface roughness and elasticity, enabling good rolling contact with the surface of the roller 2. During measurement, the positioning bracket 18 and the positioning wheels 182 together define the orientation of the measuring rod 11. The positioning wheels 182 facilitate the adjustment of the measuring rod 11's position by pushing the bracket, ensuring that the measuring rod 11 is accurately perpendicular to the axis of the roller 2, thereby ensuring measurement accuracy.

[0048] In actual operation, the continuous casting machine roller 2 opening degree detection device is first placed between the two rollers 2 to be tested, and the positioning wheel 182 and the second end of the measuring rod 11 are stably in contact with the surface of one of the rollers 2. Since the positioning bracket 18 and the positioning wheel 182 together define the orientation of the measuring rod 11, the measuring rod 11 can always be perpendicular to the axis of the roller 2 during the process of pushing the two sets of positioning wheels 182 along the surface of the roller 2, avoiding errors caused by angular deviation. The positioning bracket 18 is pushed to move the measuring rod 11 so that its first end is directly opposite the other roller 2, and the first measuring head 12 contacts the surface of the other roller 2. During the process of the first measuring head 12 contacting the surface of the roller 2, the first measuring head 12 is displaced by the reaction force of the roller 2 surface. Since the active end of the lever mechanism is connected to the first measuring head 12, the displacement of the first measuring head 12 drives the active end of the lever mechanism to move. After the amplification or reduction effect of the lever, the driven end of the lever mechanism produces a corresponding displacement. The driven end of the lever mechanism is connected to the measuring end of the measuring instrument 15. The displacement of the driven end is detected by the measuring instrument 15 and converted into measurement data. The operator can obtain the opening information of the continuous casting machine roller 2 by reading the data displayed by the measuring instrument 15. The optimal detection position is when the value of the measurement data is the smallest, which is the current gap size between the two rollers 2.

[0049] According to the continuous casting machine roller 2 opening degree detection device provided in this application embodiment, the measuring rod 11 is hollow, and the measuring head, lever mechanism and other components are installed inside, making the overall structure compact and occupying little space. The first measuring head 12 can move inside the measuring rod 11, which facilitates flexible contact with the roller 2 surface at different positions, thereby adapting to various measurement conditions. The built-in lever mechanism effectively transmits the displacement of the measuring head to the measuring instrument 15, ensuring the accuracy and sensitivity of the measurement. The two sets of positioning wheels 182 on the positioning bracket 18 roll in contact with the roller 2 surface, so that the measuring rod 11 can be stably perpendicular to the roller 2 axis, thereby significantly improving the measurement accuracy. This device is ingeniously designed and easy to operate, and can quickly and accurately detect the opening degree of the continuous casting machine roller 2, which helps to detect problems in a timely manner, ensure the normal operation of the continuous casting machine, and guarantee product quality.

[0050] Please see Figure 1 and Figure 2 According to some embodiments of this application, the measuring rod 11 may include a main rod body 111 and an adjustable rod 112. The main rod body 111 is hollow, and a first measuring head 12 and a lever mechanism are disposed inside the main rod body 111. When the first measuring head 12 is in the extended position, at least a portion of the first measuring head 12 can move to the outside of the first end of the main rod body 111. The measuring instrument 15 is mounted on the side of the main rod body 111. One end of the adjustable rod 112 is detachably connected to the second end of the main rod body 111, and the other end is provided with a second measuring head 13 corresponding to the first measuring head 12.

[0051] The main rod 111 is hollow, and the first measuring head 12 and the lever mechanism are installed inside the main rod 111 in a reasonable layout to ensure smooth movement of the measuring head and effective transmission of the lever mechanism. When the first measuring head 12 is in the extended position, at least part of it can move to the outside of the first end of the main rod 111 and contact the surface to be measured. The measuring instrument 15 is mounted on the side of the main rod 111 by a stable mounting structure, such as a welded bracket or screw fastener, for convenient measurement and data reading.

[0052] One end of the adjustable rod 112 is connected to the second end of the main rod 111 via a threaded connection, snap-fit ​​connection, or other detachable connection method. The other end of the adjustable rod 112 is equipped with a second measuring head 13, which abuts against another roller 2. The shape and material of the second measuring head 13 may be the same as or different from the first measuring head 12, depending on the actual measurement requirements. The adjustable rod 112 can be made of lightweight, high-strength materials such as aluminum alloy or titanium alloy to reduce overall weight while maintaining strength.

[0053] The first measuring head 12 and the second measuring head 13 can be set correspondingly in the axial direction of the measuring rod 11 to ensure detection accuracy.

[0054] By dividing the measuring rod 11 into two parts, the main rod body 111 and the adjustable rod 112, if either part of the main rod body 111 or the adjustable rod 112 is damaged or malfunctions, the corresponding part can be replaced individually without replacing the entire measuring rod 11, thus reducing maintenance costs. The main rod body 111 and the adjustable rod 112 can be mass-produced and quality-controlled separately, and then assembled according to order requirements, improving production efficiency and product quality stability. The split design also allows the main rod body 111 and adjustable rods 112 of different lengths to be stored separately during transportation and storage, occupying less space and facilitating management and transportation.

[0055] Please see Figure 1 and Figure 2 According to some embodiments of this application, multiple adjustable rods 112 may be provided, and the lengths of the multiple adjustable rods 112 are different. The main rod body 111 can be detachably connected to any one of the multiple adjustable rods 112.

[0056] The length differences of the multiple adjustable rods 112 are designed according to the common dimensions of continuous casting machine rollers 2 and measurement scenarios. The main rod body 111 is detachably connected to any one of the multiple adjustable rods 112. The connection method can be threaded connection, bayonet connection, or pin connection, etc. Threaded connection has the advantages of stable connection and strong adjustability; bayonet connection is simple and quick to operate; pin connection has a simple structure and high reliability.

[0057] The design of this adjustable rod 112 with its diverse lengths and its detachable connection to the main rod 111 greatly improves the versatility and adaptability of the continuous casting machine roller 2 opening degree detection device, enabling it to meet various measurement needs and improve the efficiency and accuracy of the detection work.

[0058] The number and size of the adjustable rods 112 are not limited. For example, taking a roller 2 diameter in the range of 80mm-180mm and a roller gap size generally in the range of 90mm-160mm, the length of the adjustable rods 112 can be 50mm, 70mm, 90mm, 100mm, or 120mm, etc., designed to match the length of the main rod body 111. In actual measurement, the adjustable rods 112 of the corresponding size are selected according to the size of the roller gap, so that after the main rod body 111 is connected to the adjustable rods 112, the first measuring head 12 and the second measuring head 13 can respectively abut against the two rollers 2 on both sides of the roller gap.

[0059] Please see Figure 1 and Figure 2According to some embodiments of this application, the continuous casting machine roller 2 opening degree detection device further includes a sleeve 14 and an elastic element. The sleeve 14 is sleeved on the outside of the main rod 111 and slides along the main rod 111 between a first position and a second position. When the sleeve 14 is in the first position, it extends at least partially beyond the first end of the main rod 111. When the sleeve 14 is in the second position, the end face of the sleeve 14 is flush with the first end of the main rod 111. The elastic element is connected between the sleeve 14 and the measuring rod 11, and the elastic element applies an elastic force to the sleeve 14 toward the first position.

[0060] The sleeve 14 is made of a high-strength and wear-resistant metal material, such as stainless steel, and its surface is smoothed to reduce friction. The inner diameter of the sleeve 14 is slightly larger than the outer diameter of the main rod 111, ensuring smooth sliding on the main rod 111. On the one hand, the sleeve 14 provides good protection for the internal measuring rod 11 and the first measuring head 12, effectively resisting external impacts and collisions. Furthermore, the sleeve 14 also prevents dust and other impurities from entering the measuring rod 11, thereby improving the accuracy and durability of the entire device. On the other hand, due to the large end face area of ​​the sleeve 14, its surface can make contact with the surface of the roller 2 when in contact with it. Compared to the single-point contact of the first measuring head 12, this large-area contact assists in improving contact stability, significantly enhancing the stability of the device during the detection process.

[0061] The distance by which the sleeve 14 extends beyond the first end of the main rod 111 is not greater than the distance by which the first measuring head 12 extends beyond the first end of the main rod 111, so as to reduce the influence of the sleeve 14 on the first measuring head 12.

[0062] The elastic element can be a spring, with one end of the spring fixedly connected to the sleeve 14 and the other end fixedly connected to the main rod 111. The elastic element provides appropriate elastic force, so that the sleeve 14 is stable in the first position when no external force is applied, and when a larger external force is applied, the sleeve 14 can compress the spring and slide to the second position.

[0063] In actual operation, when the detection device contacts the roller 2, the sleeve 14 is compressed and slides to the second position upon contact with the roller 2, and the elastic element absorbs energy under compression. When the impact force disappears, the restoring force of the elastic element pushes the sleeve 14 back to the first position. This design of the sleeve 14 and the elastic element effectively improves the durability, stability, and reliability of the detection device, enabling it to adapt to complex and ever-changing measurement environments.

[0064] According to some embodiments of this application, the side wall of the sleeve 14 may be provided with a clearance groove for the measuring end of the measuring instrument 15 to pass through.

[0065] The shape and size of the clearance groove are designed according to the shape and size of the measuring end of the measuring instrument 15. For example, if the measuring end of the measuring instrument 15 is cylindrical, the clearance groove can be a long strip groove with a width slightly larger than the diameter of the measuring end.

[0066] The edges of the clearance groove are polished to ensure a smooth, burr-free surface, preventing scratches and damage to the measuring end of the measuring instrument 15. In practical applications, the measuring end of the measuring instrument 15 can accurately connect and transmit data to relevant internal components through this clearance groove, without being affected by the sliding of the sleeve 14. This allows the measuring instrument 15 to operate normally, while the sleeve 14 protects the measuring rod 11 without hindering the measuring function of the measuring instrument 15.

[0067] Please see Figure 1 According to some embodiments of this application, the positioning bracket 18 is provided with a positioning hole, which is sleeved on the outside of the measuring rod 11 and slides in cooperation with the measuring rod 11.

[0068] The shape of the positioning hole matches the shape of the measuring rod 11, and the positioning hole and the measuring rod 11 are in clearance fit with a small clearance, so as to ensure the positional accuracy of the measuring rod 11 when the positioning bracket 18 slides along the measuring rod 11. Specifically, the positioning hole is sleeved on the outside of the adjustable rod 112.

[0069] In practical use, since the positioning bracket 18 is not fixedly connected to the measuring rod 11 and can slide freely, the operator can flexibly slide the positioning bracket 18 to adjust its position when facing continuous casting machine rollers 2 of different sizes and shapes. For example, for rollers 2 with larger diameters, the positioning bracket 18 is slid towards the first measuring head 12 so that the positioning wheel 182 and the second measuring head 13 can more accurately contact the surface of the roller 2; for rollers 2 with smaller diameters, the positioning bracket 18 is slid appropriately towards the second measuring head 13 to ensure the stability and accuracy of the measurement.

[0070] During the measurement process, if the contact between the positioning wheel 182 or the second measuring head 13 and the roller 2 is found to be insufficient or there is a deviation, there is no need to stop the measurement or perform complex adjustments. Simply sliding the positioning bracket 18 will correct the issue promptly, thus ensuring the continuity and reliability of the measurement data. This readily adjustable feature allows the detection device to adapt to various complex measurement environments and working conditions. Even in situations with limited space or unfavorable measurement angles, the optimal measurement position can be found by flexibly adjusting the positioning bracket 18, ensuring the accuracy and validity of the measurement results.

[0071] Please see Figure 1 According to some embodiments of this application, two sets of positioning wheels 182 are symmetrically distributed on both sides of the measuring rod 11, and the axis of the positioning wheels 182 is adapted to be parallel to the axis of the roller 2.

[0072] The positioning bracket 18 may include support legs 181 extending laterally at an angle, with two sets of positioning wheels 182 respectively mounted on the two support legs 181. The symmetrical arrangement of the two sets of positioning wheels 182 allows the measuring rod 11 to move more smoothly along the surface of the roller 2 during measurement, effectively reducing swaying and deviation. Furthermore, the axes of the positioning wheels 182 are designed to be parallel to the axis of the roller 2. In actual measurement, this parallel arrangement ensures full and uniform contact between the positioning wheels 182 and the surface of the roller 2, making the movement of the detection device along the roller 2 smoother and greatly improving the accuracy and stability of the measurement.

[0073] The diameter of the positioning wheel 182 depends on the actual measurement requirements, and is generally in the range of 2 cm to 5 cm.

[0074] When using this detection device for measurement work, thanks to the symmetrical distribution of the positioning wheels 182 and the design of the parallel axis, operators can operate more easily and accurately, significantly reducing measurement errors and effectively improving work efficiency.

[0075] Please see Figure 3 According to some embodiments of this application, each group of positioning wheels 182 includes at least two positioning wheels 182, and multiple positioning wheels 182 in the same group are coaxially connected.

[0076] A support shaft can be connected to the support leg 181, and multiple positioning wheels 182 in the same group can be coaxially connected through the support shaft. The support shaft can be made of stainless steel to ensure its strength and corrosion resistance. The support shaft and the positioning wheels 182 can be fixed together by interference fit, key connection or welding to ensure the stability of the connection and enable multiple positioning wheels 182 to rotate synchronously.

[0077] In one example, each set of positioning wheels 182 includes two positioning wheels 182, which are distributed on both sides of the support leg 181.

[0078] In practical applications, each group contains multiple coaxially connected positioning wheels 182, which increases the contact area with the object being measured and improves the stability and accuracy of the detection device during movement. Multiple positioning wheels 182 can share the pressure, reducing the impact on a single positioning wheel 182 and thus lowering measurement errors.

[0079] Please see Figure 1 and Figure 2According to some embodiments of this application, the continuous casting machine roller 2 opening degree detection device may further include an extension rod 16, which is connected to the side of the measuring rod 11 and is set at an angle to the measuring rod 11. The measuring instrument 15 is installed at the end of the extension rod 16 away from the measuring rod 11. The extension rod 16 is provided with a through hole, and the measuring end of the measuring instrument 15 is connected to the driven end of the lever mechanism through the through hole.

[0080] The extension rod 16 can be made of high-strength aluminum alloy to reduce weight while ensuring strength. One end of it can be connected to the side of the measuring rod 11 by welding, screw fastening or clipping, and set at a certain angle with the measuring rod 11. The size of the angle depends on the convenience of actual operation and the optimal observation angle of the measuring instrument 15, and can be between 30 degrees and 90 degrees.

[0081] The measuring instrument 15 is mounted on the end of the extension rod 16 away from the measuring rod 11. The extension rod 16 has a through hole extending axially, through which the measuring end of the measuring instrument 15 can be connected to the driven end of the lever mechanism inside the measuring rod 11. The diameter of the through hole is slightly larger than the diameter of the measuring end of the measuring instrument 15 to ensure that the measuring end can pass smoothly without excessive wobbling.

[0082] In one example, when the extension rod 16 is long, a trigger rod can be provided in the through hole of the extension rod 16. One end of the trigger rod is connected to the driven end of the lever mechanism, and the other end is connected to the measuring end of the measuring instrument 15, so that the action of the lever mechanism is transmitted to the measuring instrument 15 through the trigger rod.

[0083] In practical use, the extension rod 16 allows the measuring instrument 15 to be placed in a position that is more convenient for the operator to observe and operate. For example, when the measurement space is relatively narrow or the measurement angle is relatively special, extending the measuring instrument 15 with the extension rod 16 allows the operator to read the measurement data more clearly, while also preventing the measuring instrument 15 from being interfered with or bumped by the surrounding environment, thus ensuring the accuracy and stability of the measurement.

[0084] Please see Figure 1 and Figure 2 According to some embodiments of this application, a hand handle 17 may be fitted over the extension rod 16.

[0085] The handle 17 can be a plastic sleeve 14. By attaching the handle 17 to the extension rod 16, it is convenient to grasp the handle 17 when using the detection device, and the hand temperature is prevented from being transferred to the inside of the extension rod, which would affect the detection accuracy. This makes the operation convenient and ensures the accuracy of the detection.

[0086] The operating procedure of the continuous casting machine roller 2 opening degree detection device provided in the embodiments of this application is as follows:

[0087] Before using the instrument for measurement, the appropriate adjustable rod 112 must first be selected according to the specific numerical range of the opening degree of the roller 2 to be measured. The adjustable rod 112 is precisely fixed to the main rod body 111 to ensure the accuracy of the measurement. Next, the lever mechanism, measuring instrument 15, and positioning bracket 18 are assembled in the correct order, ensuring that each part is tightly connected to guarantee the overall stability and measurement accuracy of the instrument.

[0088] After assembly, the measuring instrument 15 is first calibrated numerically. A standard template with known values ​​or an outside micrometer with the corresponding range can be used for calibration.

[0089] During the measurement of the opening, the operator needs to hold the positioning bracket 18 and use it in conjunction with the lever mechanism to accurately measure the distance between the upper and lower rollers on the outer side of the sector segment. To ensure the accuracy of the measurement results, the positioning bracket 18 must be kept perpendicular to the axis of the roller 2 being measured, so that the measuring rod 11 is perpendicular to the axis of the roller 2 being measured. This can avoid errors caused by angular deviations.

[0090] When the positioning bracket 18 contacts the roller 2 being tested, it is necessary to ensure that the four positioning wheels 182 on the positioning bracket 18 are in complete contact and evenly distributed on the roller surface of the roller 2 being tested. The operator needs to move back and forth in the radial direction of the roller 2 and carefully observe the display of the measuring instrument 15 until the value reaches the minimum value. At this point, it indicates that the detection position has been adjusted to the optimal state, and the detection process is complete. This series of operational steps is to ensure the accuracy and reliability of the measurement data, thereby providing a solid foundation for subsequent data analysis and decision-making.

[0091] This testing device can measure the diameter of roller 2 from 80mm to 180mm; it can measure the roller gap size from 90mm to 160mm; the measurement is accurate, and the measurement accuracy of the measuring instrument 15 can reach 0.01mm or higher; it has a simple structure, low cost, and is easy to use, meeting the practical engineering needs of small fan-shaped sections with an opening of 90mm-160mm.
