Description

Technical Field

[0001] This invention relates to the field of metallurgical equipment installation and manufacturing technology, specifically to a conical roller conveyor alignment tool. Background Technology

[0002] In fields such as metallurgical cold rolling, non-ferrous metal ingot, plate, strip conveying, and high-precision film slitting, variable-diameter conical roller conveyors (also known as "waist drum-shaped roller conveyors") with thicker ends and a thinner middle section are core equipment for solving the problem of "center positioning offset" in material conveying. Through the guiding constraint of the large-diameter sections at both ends of the conical roller conveyor and the supporting cooperation of the thinner diameter section in the middle, it can effectively prevent strips and plates from shifting to the edges during high-speed conveying, while reducing the contact area between the conical roller conveyor and the material to lower the risk of surface scratches. During the installation and maintenance of this type of roller conveyor, it is necessary to calibrate the following: the elevation deviation of the conical surfaces at both ends of the conical roller conveyor relative to the reference surface; the horizontal deviation of the conical roller surfaces at both ends of the conical roller conveyor; the relative horizontal deviation of the conical roller surfaces of each conical roller conveyor; the deviation of the conical roller conveyor relative to the reference center line; and the perpendicularity of the conical roller conveyor axis relative to the center line. If the calibration deviation exceeds 0.1mm, it can easily lead to "snake-like movement" of the material or strip deviation, and in severe cases, it can cause malfunctions such as uneven wear of the non-strip and conical roller conveyors.

[0003] Currently, the industry mainly adopts the following existing technical solutions for the alignment of tapered roller conveyors that are coarse at both ends and fine in the middle:

[0004] Segmented measuring tool method: The operator first uses a precision level with an indium steel ruler to measure the elevation of the highest point (shoulder point) of the tapered roller conveyor at both ends, and judges the elevation deviation and horizontal deviation; the rocker arm method (inner micrometer plus pendulum) is used to measure the perpendicularity of the tapered roller conveyor axis relative to the center line; the tapered roller conveyor is centered with a ruler, and then the center deviation of the tapered roller conveyor is checked with a hanging line and a ruler. Although this method is recommended in the "Code for Construction and Quality Acceptance of Installation Engineering of Nonferrous Metal Processing Machinery" (GB51059-2014) and the "Code for Installation and Acceptance of Rolling Mill Machinery Equipment" (GB50386-2016), it has obvious limitations: The elevation measurement error is large. When directly measuring the elevation of the highest point of the conical roller conveyor surface, there is usually a chamfer at that location, and the chamfering process is not strictly controlled, which will affect the length dimension of the conical surface. The length dimension deviation will directly affect the diameter of the conical roller conveyor at this point. If the diameter at the elevation measurement point is different, even if the measured elevation is the same, it does not mean that the elevation requirement is met. Elevation measurement is difficult. An indium steel ruler must be erected at the highest point of the conical roller conveyor's inclined surface during elevation measurement. Since it is only a point contact, additional measures are needed to ensure that the ruler is vertical and horizontal, and that the measuring point is at the highest point of the conical roller conveyor surface. The center measurement deviation is large. Because the center of the conical roller conveyor (axial direction) must be found during measurement, a steel tape measure is generally used. However, the conical roller conveyor is a conical surface, making centering difficult, which leads to a large measurement deviation. The above measurement errors cannot guarantee that the actual deviation of the tapered roller conveyor is within the technical requirements.

[0005] Photoelectric alignment of roller conveyors: Utilizing a U-shaped symmetrical V-shaped plate spanning the rollers as a positioning base, the device is fixed to the rollers via an adjustable chain and fastening assembly. The position of the laser alarm device is adjusted using a micrometer on the upper end of a swing arm. With the laser contacting the longitudinal centerline of the unit as the reference, the rollers are manually rotated to read the micrometer readings on both sides to calculate the verticality, thus achieving roller conveyor alignment. This technology is documented in invention patent CN111389933A. It solves the problems of low accuracy and high labor and time consumption associated with traditional steel wire + micrometer alignment by combining "mechanical fixing + photoelectric positioning." For the special structure that is thick at both ends and thin in the middle, there are still adaptation defects: the U-shaped and V-shaped plates can only fit a single cross section of the conical roller conveyor and cannot be adapted to the transition arc surface. The positioning is prone to deviation and the contact is unstable. Additional tools are required to measure key parameters such as the symmetry of the diameter at both ends. In addition, the chain needs to be manually adjusted repeatedly to adapt to different roller conveyor specifications and to read the micrometer values. Data processing depends on manual calculation, which accounts for more than 30% of the total alignment time. At the same time, it can only output the deviation of the single parameter of verticality and cannot synchronously link the coordinated deviation relationship of "symmetry at both ends - straightness in the middle - overall parallelism". Multiple disassembly and adjustment are required, which is inefficient. Summary of the Invention

[0006] This invention provides a tapered roller conveyor alignment tool, the purpose of which is to improve the measurement accuracy of tapered roller conveyors while reducing manual operation.

[0007] The technical solution of the present invention to solve the above-mentioned technical problems is as follows:

[0008] A conical roller conveyor alignment tool is installed on a conical roller conveyor. A center line is provided on the side of the conical roller conveyor. The tool includes an inside micrometer with a suction seat. The suction seat of the inside micrometer is attached to the outer surface of a magnetic angle gauge. Two angle gauges are fixedly mounted on the thick conical surfaces at both ends of the conical roller conveyor by suction. An indium steel ruler is provided on the upper surface of one of the angle gauges. The indium steel ruler is used to measure the elevation deviation of the roller conveyor.

[0009] Furthermore, a level is provided on the upper surface of another inclined gauge.

[0010] Furthermore, the slant gauge has a slant surface that matches the tapered surface of the roller conveyor.

[0011] Furthermore, the outer surface of the inclination gauge is equipped with a magnetic chuck or a vacuum chuck.

[0012] Furthermore, the suction base of the inside micrometer is a magnetic suction base.

[0013] A method for aligning using the aforementioned tapered roller conveyor alignment tool includes the following steps:

[0014] S1. Installation preparation and baseline establishment;

[0015] S11. Centerline Determination and Marking: In the roller conveyor installation area, the centerline is determined and marked using a theodolite or total station, and the tapered roller conveyor is hoisted to the installation position using hoisting equipment.

[0016] S12. Assembly and fitting of the angle gauges: The two angle gauges are fixedly set on the thick section of the conical surface at both ends of the conical roller conveyor. The angle gauges and the conical surface fit tightly together under the action of gravity.

[0017] S13. Deployment of the inside micrometer with suction base: The inside micrometer with suction base is stably attached to the outer side of the angle gauge through the suction base, so that the center height of the inside micrometer is aligned with the center line, and is used to measure the distance between the outer side of the angle gauge and the center line.

[0018] S14. Deployment of Indium Steel Ruler: Place the indium steel rulers sequentially on the upper surface of the inclination gauge to ensure that the indium steel rulers are stable and do not shift.

[0019] S2. Installation and alignment measurement of tapered roller conveyor;

[0020] S21. Initial positioning of the tapered roller conveyor: The tapered roller conveyor is quickly and initially positioned by adsorption and fixation using an inclination gauge.

[0021] S22. Center Deviation Measurement and Adjustment: Read the value of the inside micrometer, obtain the distance between the outer side of the inclined gauge at both ends of the tapered roller conveyor and the center line, calculate the distance difference, and adjust the tapered roller conveyor to control the distance difference to ≤0.2mm;

[0022] S23. Measurement and adjustment of elevation deviation: Use a level to read the scale of the indium steel ruler to obtain the elevation value, and adjust the tapered roller conveyor to control the elevation difference between the two ends to ≤0.2mm;

[0023] S24. Measurement and adjustment of horizontal deviation: Use the precision level on the upper part of the inclined gauge to measure the horizontality of the inclined gauge in the longitudinal and transverse directions of the tapered roller conveyor, obtain the horizontal deviation, and adjust the tapered roller conveyor to control the horizontal deviation in both directions to ≤0.05mm / m;

[0024] S3. Accuracy Verification and Finalization:

[0025] Repeat steps S22, S23, and S24 to perform multiple measurements and record the results. Ensure that the center deviation and elevation deviation are both stable within ≤0.2mm and the levelness deviation is controlled within 0.05mm / m. Use the average value of multiple measurements as the final result.

[0026] The present invention has the following beneficial effects:

[0027] Measurement accuracy has been fundamentally improved. In terms of tool design, the precise fit between the inclination gauge and the tapered roller conveyor eliminates reference surface errors, laying a solid foundation for high precision. The indium steel ruler, due to its extremely low coefficient of thermal expansion, effectively resists the interference of ambient temperature fluctuations on the measurement. Methodologically, centerline and elevation measurements are integrated into a single process, and through strict tolerance control of ≤0.2mm and a verification mechanism that averages measurements over multiple time periods, random errors are systematically eliminated, ensuring the ultimate accuracy and reliability of the alignment results.

[0028] Secondly, in terms of tools, both the angle gauge and the inside micrometer are fixed by suction, enabling quick installation and stable locking of the tools. This completely frees the operator's hands and avoids fatigue and shaking errors caused by manual support in traditional methods. In terms of methodology, the alignment process is broken down into clear, standardized steps, and a spirit level is introduced for coarse adjustments. This makes the entire operation smooth and orderly, significantly shortening the time for adjustments and repeated verifications, and multiplying work efficiency.

[0029] The rigid measuring system formed by tool adsorption effectively resists external interference throughout the alignment process, ensuring the stability and repeatability of readings. Meanwhile, the combination of an indium steel ruler and a magnetic chuck gives this solution excellent adaptability, enabling it to handle alignment tasks for conical roller conveyors of different specifications and materials with ease.

[0033] Figures 1 to 3 The reference numerals in the attached figures are respectively: center line 1, inside micrometer 2, bevel gauge 3, indium steel ruler 4, tapered roller conveyor 5, and level 6. Detailed Implementation

[0034] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0035] Please refer to Figure 1-3 This embodiment describes in detail a tapered roller conveyor alignment tool. Its core concept is to integrate the measurement functions of multiple measurement benchmarks (center line, elevation) through an integrated tool set, and to achieve rapid and stable installation with the tapered roller conveyor 5 by using an adsorption fixing method. This significantly improves the accuracy and efficiency of alignment measurement while reducing manual support and repeated disassembly and assembly operations.

[0036] The tool is installed on the tapered roller conveyor 5. A center line 1 is provided on the side of the tapered roller conveyor 5. It includes an inner micrometer 2 with a suction seat. The suction seat of the inner micrometer 2 is attached to the outer side of the inclined gauge 3. The inner micrometer 2 is used to measure the center deviation of the roller conveyor. An adsorption device is provided on the bottom surface of the inclined gauge 3. The two inclined gauges 3 are fixed on the thick section conical surface at both ends of the tapered roller conveyor 5 by adsorption. An indium steel ruler 4 is provided on the upper surface of one of the inclined gauges 3 (the indium steel ruler 4 is placed on the two inclined gauges 3 in sequence). The indium steel ruler 4 is used to measure the elevation deviation of the roller conveyor.

[0037] Centerline 1 serves as the core reference line for the entire center measurement process, used to determine the theoretical center position of the roller conveyor installation. Its deviation control directly affects the stability of the material conveyed by the roller conveyor. The inclination gauge 3 is a key component that directly connects this tool to the tapered roller conveyor 5 and establishes the measurement reference. It is manufactured using high-precision CNC machining, with strict control over form and position tolerances such as flatness and perpendicularity (e.g., flatness ≤ 0.03mm, roughness Ra 1.6μm). It is used to fit the end of the roller conveyor, establishing a measurement reference surface. It is compatible with the conical surfaces of the thicker sections at both ends of the tapered roller conveyor, providing fundamental support for elevation and center measurements. The inside micrometer 2 is itself a high-precision length measuring tool. Its feature is a suction seat that stably adheres to the outer side of the inclination gauge. Utilizing the high-precision measurement characteristics of the micrometer (accuracy up to 0.01mm), the distance between the outer side of the inclination gauge and centerline 1 is measured, achieving precise detection of the roller conveyor center deviation and providing accurate data support for center deviation adjustment. By attaching the inside micrometer 2 to the inclined gauge 3, the axial direction of its measuring rod is naturally determined.

[0038] During deployment, by adjusting the adsorption position of the inside micrometer 2 on the outer side of the bevel gauge 3, its measuring direction can be precisely aligned with the pre-set center line 1. In this way, the reading of the inside micrometer 2 directly reflects the vertical distance from the outer side of the bevel gauge 3 (i.e., the representative surface at this end of the tapered roller conveyor 5) to the center line 1. Since the bevel gauge 3 is stably attached to the tapered roller conveyor 5 through adsorption, and the inside micrometer 2 is stably attached to the bevel gauge 3, the entire measuring system forms a rigid whole, effectively avoiding relative displacement and reading fluctuations during the measurement process.

[0039] In order to achieve quick installation and stable fixation of the inclination gauge 3 on the tapered roller conveyor 5, avoid errors caused by tool displacement during measurement, and reduce manual pressing and support operations, a stop (stop) is provided on the outside of the inclination gauge. When placed on the tapered roller conveyor, it fits tightly with the tapered roller conveyor by gravity on the inclined surface.

[0040] In the two inclination gauges 3, their upper surfaces are selected as the reference plane for elevation measurement. An indium steel ruler 4 is mounted on the upper surface of the inclination gauge 3. The indium steel ruler 4 is a precision ruler made of indium steel alloy, characterized by its extremely low coefficient of thermal expansion, minimal impact from changes in ambient temperature, and, when used with equipment such as a level, ensures the stability of elevation readings during long-term measurements.

[0041] Furthermore, a level 6 is provided on the upper surface of the inclined gauge 3. Optionally, a level 6 is provided on the upper surface of the inclined gauge 3. This level 6 is used to measure the levelness of the inclined gauge 3 in the longitudinal (axial) and transverse directions of the roller body, obtaining the levelness deviation. Large level deviations can be quickly eliminated, laying a good foundation for subsequent precision adjustments (center, elevation), and improving overall adjustment efficiency.

[0042] Furthermore, the slant gauge 3 has a slant surface that matches the conical surface of the tapered roller conveyor 5. Each slant gauge 3 is designed with a slant surface that precisely matches the coarse section of the tapered roller conveyor 5. The cone angle of this slant surface matches the cone angle of the corresponding end of the tapered roller conveyor 5, ensuring that when the slant gauge 3 is placed on the conical surface, the slant gauge contacts both rollers simultaneously, rather than unreliable point or line contact. This design eliminates measurement errors introduced by mismatched reference surfaces, providing a stable and reliable mounting platform for all subsequent precision measurements.

[0043] The outer surface of the inclination gauge 3 is preferably a magnetic chuck. Specifically, when using a magnetic chuck, it is suitable for a tapered roller conveyor 5 made of ferromagnetic material, and the inclination gauge 3 is firmly adsorbed onto the surface of the roller conveyor by a strong magnetic force.

[0044] Furthermore, the suction base of the inside micrometer 2 is a magnetic suction base. The inside micrometer 2 with the suction base is the core measuring instrument used to measure center deviation. This magnetic suction base can be firmly attached to the outer metal surface of the angle gauge 3.

[0045] The present invention also provides an alignment method using the above-mentioned tools, which makes full use of the characteristics of the tools to achieve efficient and high-precision alignment.

[0046] S1. Installation Preparation and Baseline Establishment

[0047] S11. Centerline Determination and Marking: In the roller conveyor installation area, firstly, using high-precision measuring instruments such as a theodolite or total station, accurately determine the theoretical centerline of the roller conveyor system according to the equipment installation drawings. Then, using ink lines, laser marking instruments, or other permanent or temporary marking methods, clearly mark this centerline 1 on the foundation. This centerline 1 will serve as the reference for the entire alignment process.

[0048] S12. Assembly and Adaptation of Inclined Gauges: Before or during the initial adjustment phase after the conical roller conveyor 5 is hoisted into place, the inclined gauges 3 are installed. Place the two inclined gauges 3 on the thicker conical surfaces at both ends of the conical roller conveyor 5. During placement, ensure that the inclined surface of the inclined gauge 3 is completely in contact with the conical surface of the roller conveyor. Then (e.g., by turning on the magnetic switch or starting the vacuum pump), firmly attach it to the conical roller conveyor 5. This step replaces manual support with adsorption fixation, establishing a stable and reliable reference platform for subsequent measurements. During operation, it should be checked and confirmed that the inclined gauges 3 are not loose or wobble.

[0049] S13. Deployment of the inside micrometer with suction mount: Attach the inside micrometer 2 with suction mount to the outer surfaces of the two bevel gauges 3. During attachment, the position and angle of the inside micrometer 2 need to be finely adjusted so that the extension and retraction direction of its measuring rod is strictly perpendicular to the center line 1, i.e., ensure that its center height is aligned with the center line 1. Initial alignment can be achieved by visually inspecting with a string or using a small right-angle ruler or other auxiliary tools. After adjustment, tighten the suction mount of the inside micrometer 2 to ensure that it does not shift during measurement. At this point, the two inside micrometers 2 are used to measure the distances L1 and L2 from the outer surfaces of the two bevel gauges 3 to the center line 1, respectively.

[0050] S14. Indium Steel Ruler Deployment: Place the indium steel ruler 4 on the upper surface of the pre-designated bevel gauge 3. During placement, ensure that the bottom surface of the indium steel ruler 4 is clean and in full contact with the upper surface of the bevel gauge 3.

[0051] S2. Installation and Alignment Measurement of Conical Roller Conveyor

[0052] S21. Preliminary Positioning of the Conical Roller Conveyor: Using hoisting equipment (such as overhead cranes or gantry cranes), the conical roller conveyor 5, with the alignment tools already installed, is hoisted to the installation position and roughly aligned with the installation reference. Since the inclination gauges 3 are fixed by adsorption, they can maintain their relative position with the roller conveyor during hoisting and preliminary positioning, achieving rapid preliminary positioning of the tools and eliminating the need to install the tools after hoisting.

[0053] S22. Measurement and adjustment of center deviation:

[0054] Measurement: Read the value of the inside micrometer 2 installed on the inclination gauge 3 to accurately obtain the spacing L1.

[0055] Calculation and Judgment: Calculate the difference between the measured distance L1 and the theoretical center deviation L, ΔL = L1 - L. Theoretically, when the distance between the centerline of the tapered roller conveyor 5 and the base centerline 1 is the same as the theoretical center distance, ΔL should be zero or within a very small allowable range.

[0056] Adjustment: If ΔL is greater than the allowable deviation (e.g., ≤0.2mm), it indicates that the tapered roller conveyor 5 has a center deviation. In this case, it is necessary to slightly move one or both ends of the tapered roller conveyor 5 by fine-tuning the roller conveyor base or support mechanism, observing the change in the reading of the inside micrometer 2 during the adjustment process until ΔL meets the accuracy requirement of ≤0.2mm. Since the measuring tool is fixedly installed on the roller conveyor, the reading change can be observed in real time during the adjustment process, achieving dynamic adjustment and high efficiency.

[0057] S23. Measurement and adjustment of elevation deviation:

[0058] Measurement: Using a high-precision level, aim at the indium steel ruler 4 placed on the inclination gauge 3 and take the reading to obtain the elevation values ​​H1 and H2 at both ends. Look up the theoretical elevation H (or set the indium steel ruler 4 on the other end of the inclination gauge 3 and obtain the elevation value) H2.

[0059] Calculation and Judgment: Calculate the difference in elevation ΔH = |H1 / H2- H|.

[0060] Adjustment: If ΔH is greater than the allowable deviation value (e.g., ≤0.2mm), it indicates that there is an elevation deviation (tilt) in the tapered roller conveyor 5. Raise or lower one end of the roller conveyor by adjusting the elevation adjusting bolts or shims on the roller conveyor base or support mechanism, while observing the change in the level reading on the indium steel ruler 4, until ΔH meets the accuracy requirement of ≤0.2mm.

[0061] S24. Horizontal Deviation Measurement and Adjustment: Use the precision level 6 on the upper part of the inclined gauge 3 to measure the horizontality of the inclined gauge 3 in the longitudinal (axial) and transverse directions of the roller body, obtain the horizontal deviation, and control the horizontal deviation in both directions to ≤0.05mm / m by adjusting the tapered roller conveyor 5. This step can quickly eliminate large horizontal deviations, lay a good foundation for subsequent precision adjustments (center, elevation), and improve the overall adjustment efficiency.

[0062] S3, Accuracy Verification and Finalization

[0063] Comprehensive Accuracy Verification: After initial adjustment to the target accuracy, verification is required to ensure the reliability and stability of the measurement results. Repeat steps S22 (center deviation measurement), S23 (elevation deviation measurement), and S24 at least 2-3 times. Record the data after each measurement.

[0064] Data stability assessment: Observe the data from multiple measurements to ensure that the center deviation ΔL and elevation deviation ΔH can be stably controlled within the range of ≤0.2mm and the levelness deviation is controlled within the range of 0.05mm / m. The average value of multiple measurements is used as the final result.

[0065] Multiple measurements: To eliminate the influence of random factors, multiple measurements can be performed, and the average of the results can be used as the basis for the final calibration result.

[0066] Final Steps: After confirming that all deviations meet the design requirements, tighten all base bolts to complete the final fixing of the tapered roller conveyor 5. After fixing, a final verification measurement can be performed again. Finally, remove the alignment tools (turn off the adsorption device and remove the inside micrometer 2, indium steel ruler 4, spirit level 6, and inclination gauge 3).

[0067] By combining the above tools and methods, this invention breaks down the complex work of aligning tapered roller conveyors into standardized and streamlined steps, and ensures the stability and accuracy of each measurement step through specialized tools. Ultimately, this significantly improves alignment accuracy and efficiency while greatly reducing manual operation and subjective judgment.

[0068] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
