Description

Technical Field

[0001] This invention relates to the field of installation and commissioning technology for ring coolers, and in particular to a method for measuring and positioning the support rollers of a ring cooler. Background Technology

[0002] The multi-functional blower ring cooler (hereinafter referred to as the ring cooler) is one of the most important pieces of equipment in the steel production process. With the increasing size of ring coolers today, they must be assembled and debugged on-site. The quality of the on-site installation directly affects the operating performance and service life of the ring cooler.

[0003] During operation, the annular cooler uses several interconnected rotating frame trolleys that move in a ring to support the hot ore. Blowers evenly distributed around the perimeter of the annular cooler blow cold air through the lower half of the rotating frame trolleys, passing over the hot ore layer for heat exchange. The exhaust gas carries away the heat, thus cooling the hot ore. Therefore, the stable operation of the rotating frame is crucial for the annular cooler.

[0004] The support rollers serve as the foundation for the circumferential motion of the rotary frame trolley. During operation, centrifugal force exerts axial loads on the support rollers, which operate under conditions of dust and fluctuating temperatures, leading to a high failure rate and a tendency for positional and dimensional deviations. Therefore, the positional accuracy of the support rollers directly affects the stability of the rotary frame trolley during operation, ultimately determining its safe and stable operation in actual production. Thus, whether during the initial design installation or subsequent periodic calibration, precise positional measurement of the support rollers is essential.

[0005] like Figure 1As shown, multiple support rollers are mounted on the upper planes of the main beam and intermediate beam of the frame plane beam, respectively, surrounding the central measuring platform. Each main beam or intermediate beam has two support rollers, symmetrically arranged on both sides of the annular center line of the ring cooler (i.e., divided into inner ring support rollers and outer ring support rollers). Several support rollers are combined to form two support rings located on both sides of the annular center line, used to support the rotating body. Traditional measurement methods use a total station electronic distance measuring instrument (hereinafter referred to as total station) set on a central measuring platform to measure and position the inner ring support roller. However, the ring cooler has inner ring columns for installing components such as plane beams and side rollers. These inner ring columns obstruct the view of the inner ring support roller, making it impossible to measure some inner ring support rollers with the total station. At the same time, the inner ring support roller also obstructs the outer ring support roller, making it impossible to directly observe and position the outer ring support roller. The relative installation distance between the inner and outer ring support rollers can only be measured by string or tape measure, which brings great inconvenience to the installation and measurement of the support roller and cannot guarantee the measurement accuracy. Therefore, there is an urgent need to develop an operation method suitable for positioning and measuring the support roller of the ring cooler. Summary of the Invention

[0006] This invention provides a method for measuring and positioning the support rollers of a ring-type cooler, which can solve the technical problems of inconvenient observation, complicated procedures, and low measurement accuracy caused by traditional measurement methods.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] A method for measuring and positioning the installation of a ring-type cooler support roller includes an installation auxiliary device. The installation auxiliary device includes a reference base, a wing plate, a top rod, and a total station. The reference base is placed on the top of the support seat of the inner ring support roller. A center line is provided on the front end face of the reference base. The wing plate is horizontally arranged in a cuboid structure, fixed to the top surface of the reference base, and extends symmetrically with respect to the center line of the reference base. Vertical graduation lines are symmetrically distributed at both ends of the wing plate with respect to the center line of the reference base. The top rod is installed between the inner and outer ring support rollers. The total station is located at the center of the ring-type cooler and is used to measure and calibrate the installation dimensions of the inner ring support roller in conjunction with the wing plate. Right-angle notches are provided at both ends of the top rod, forming a transverse surface and a longitudinal surface. The transverse surfaces of the two right-angle notches are parallel to each other, and the longitudinal surfaces of the two right-angle notches are located in the same plane. Symmetrical horizontal graduation lines are provided in the middle of the top rod, and the top rod is symmetrically distributed with respect to these horizontal graduation lines.

[0009] The specific installation measurement and positioning method includes the following steps:

[0010] Step S1: Establish the measurement reference for the inner ring support roller; place the reference base on the top surface of the support seat in front of the inner ring support roller, and align the center line of the reference base with the vertical bisector of the inner ring support roller; place the back of the wing plate tightly against the front end face of the inner ring support roller, and provide vertical scale lines symmetrically distributed around the center line of the reference base at both ends of the wing plate; place a spirit level on the top surface of the reference base, and adjust the bottom of the reference base using shims until the top surface of the reference base is adjusted to a horizontal position;

[0011] Step S2: Adjust the axial and radial positions of the inner ring support roller; use a total station to measure the actual values ​​of the distances K between the center of the ring cooler and the two vertical scale lines of the wing plate, obtaining left K and right K. Adjust and calibrate the axial installation position of the inner ring support roller according to the deviation of left K and right K; the lateral distance between the vertical scale lines on the left and right sides of the wing plate is w, where the distance from one vertical scale line to the perpendicular bisector of the inner ring support roller is w / 2, and the thickness of the wing plate is d. Based on the geometric relationship of triangles, calculate the actual distance K1 between the front wall of the inner ring support roller and the center point of the ring cooler, i.e. Then, based on the difference between the sum of K1 and d and the design dimension value R1, the vertical offset e from the center of the annular cooler to the central axis of the inner ring support roller is calculated, i.e. Adjust and calibrate the radial installation position of the inner ring support roller so that the vertical offset e is about 0. When adjusting the vertical offset e, make sure that the deviation of the left K and the right K is within the qualified range. Once the vertical offset e and the deviations of the left K and the right K meet the requirements, the position of the inner ring support roller can be fixed.

[0012] Step S3: Install the push rods; set two push rods, with the distance between the two transverse surfaces on each push rod set to N; adjust the outer ring support roller so that the two push rods can just fit between the rear wall of the inner ring support roller body and the front wall of the outer ring support roller body; the two push rods are parallel to each other and are on the same horizontal plane as the central axis from the inner ring support roller to the outer ring support roller, so that the two transverse surfaces of the push rods are respectively in contact with the rear wall of the inner ring support roller body and the front wall of the outer ring support roller body, and at the same time, the longitudinal surfaces of the two push rods are respectively in contact with the rims of the inner ring support roller body and the outer ring support roller body;

[0013] Step S4: Measure the axial and radial offsets of the outer ring support roller; use a feeler gauge to measure the gap n when the transverse surface in the right-angle notch is in contact with the side wall of the corresponding roller body, and the gap m when the longitudinal surface in the right-angle notch is in contact with the rim of the corresponding roller body, and determine the axial and radial positions of the outer ring support roller based on the gap measurements.

[0014] Step S5: Adjust the axial and radial positions of the outer ring support roller; adjust the axial and radial positions of the outer ring support roller so that the gaps n and m between the transverse and longitudinal surfaces on the two push rods and the corresponding roller body contact surfaces meet the process requirements, so that the central axis of the outer ring support roller body is aligned with the central axis of the inner ring support roller body, and the longitudinal distance between the rear side wall of the inner ring support roller body and the front side wall of the outer ring support roller body is N, thereby completing the adjustment and calibration of the axial and radial installation positions of the outer ring support roller.

[0015] Step S6: Obtain the positioning reference of the rotary frame trolley; the rotary frame trolley is set on the inner ring support roller and the outer ring support roller, and the distance between the center of the ring cooler and the center line of the rotary frame trolley is set as R0, which is located at the center of the central axis of the inner ring support roller and the outer ring support roller; obtain the R0 reference point according to the position of the inner ring support roller and the outer ring support roller to the center of the ring cooler to facilitate the subsequent installation and positioning of the rotary frame trolley.

[0016] Step S7: According to steps 1 to 6, measure and position all inner ring support rollers from the center of the ring cooler, and accurately adjust the position of the corresponding outer ring support rollers according to the inner ring support rollers.

[0017] Further, in step S1, a laser level is used to align the vertical bisector of the center hole of the inner ring support roller, and the center line of the reference base is aligned with the vertical bisector of the inner ring support roller.

[0018] Furthermore, in step S2, a prism is required for the total station setup. The prism is set on the mounting platform on the front side of the inner ring support roller, maintaining the same height as the wing plate. The heights of the total station and the prism are input into the computer that comes with the total station, and the slope distance is automatically converted into the horizontal distance. The left K and right K measurements can only be performed after the total station is set up and debugged.

[0019] Furthermore, in step S2, after each adjustment of the inner ring support roller position, the center line of the reference base must be realigned with the vertical bisector of the inner ring support roller, the top surface of the reference base is adjusted to be horizontal, the back of the wing plate is pressed tightly against the front end face of the inner ring support roller, and then the left K and right K are measured until the vertical offset e and the deviations of the left K and right K meet the requirements.

[0020] Further, in step S3, a laser level is installed on the plane beam between the inner ring support roller and the outer ring support roller. The laser level emits two horizontal laser lines, one in front and one behind, which pass through the center holes of the inner ring support roller and the outer ring support roller, respectively, so that the laser level projects horizontal laser lines on the opposite surfaces of the inner ring support roller and the outer ring support roller. Marks are set on the left and right rims of the rear side wall of the inner ring support roller and the left and right rims of the front side wall of the outer ring support roller according to the horizontal laser lines. One of the push rods is placed at the left rim mark of the support roller, and the other push rod is placed at the right rim mark of the two rollers, so that the two transverse surfaces of the push rods are in contact with the rear side wall of the inner ring support roller and the front side wall of the outer ring support roller, respectively. At the same time, the longitudinal surfaces of the two push rods are in contact with the rims of the inner ring support roller and the outer ring support roller, respectively, so that the two push rods are parallel to each other and kept on the same horizontal plane as the center hole.

[0021] Further, in step S6, the laser level is adjusted so that the longitudinal horizontal laser line projected by the laser level is simultaneously aligned with the central axis of the inner ring support roller and the central axis of the outer ring support roller, and the transverse horizontal laser line projected by the laser level is simultaneously aligned with the symmetrical horizontal markings of the two top rods. Finally, the longitudinal and transverse horizontal laser lines projected by the laser level intersect and fall on the plane beam between the inner and outer ring support rollers to form a cross line. The intersection of the cross line is the location of R0 on the plane beam used to install the support roller, thereby obtaining the beam surface R0 reference point on the plane beam.

[0022] The beneficial effects of this invention are:

[0023] 1) The measurement and positioning method of this invention adopts a symmetrical wing plate structure. A new measurement benchmark for the inner ring support roller is established through the base and wing plate. This solves the technical problems of inconvenient observation, complicated procedures, and low measurement accuracy caused by the obstruction of the line of sight of the inner ring column in the traditional installation scheme. The total station set in the center of the ring cooler can avoid the obstruction of the line of sight of the inner ring column and directly observe the symmetrical vertical engraving line of the wing plate. This can transform the indirect observation of the traditional measurement method into direct visual observation, and make some items that cannot be detected directly measurable. With this invention, a circumferential measurement can be performed directly from the central measuring platform, measuring all inner ring support rollers at once, and accurately adjusting the outer ring support rollers according to the inner ring support rollers. The detection is intuitive and convenient, the detection efficiency is greatly improved, and higher reliability and accuracy can be guaranteed.

[0024] 2) The installation position accuracy of the support roller is a necessary inspection item during the installation of the ring cooler. However, the existing support rollers are basically designed as universal standard parts, consisting of a support seat and a roller body. This invention constructs a simple geometric relationship using a total station and a wing plate, and then guides the adjustment of the support roller by comparing the theoretical and measured values ​​of relevant dimensions. It is convenient to operate, simple to calculate, not limited by the size of the roller body, and has wide applicability.

[0025] 3) The push rods used in this invention have right-angle notches at both ends to ensure stable fit with the rim of the support roller and to ensure that the two push rods of the same length are parallel to the axis of the support roller, thereby ensuring the relative installation position dimensions between the outer ring support roller and the inner ring support roller; when the push rods are installed according to the technical requirements, they can accurately reflect the installation position of the outer ring support roller and guide the adjustment direction of the corresponding outer ring support roller.

[0037] Reference Figures 1 to 5 As shown, a method for measuring and positioning the support roller of a ring-type cooler includes an installation auxiliary device. The installation auxiliary device includes a reference base 1, a wing plate 2, a top rod 3, and a total station 4. The reference base 1 is placed on the top of the support seat 6 of the inner ring support roller 5. A center line 11 is provided on the front end face of the reference base 1. The wing plate 2 is horizontally arranged in a cuboid structure, fixed to the top surface of the reference base 1, and extends symmetrically about the center line 11 of the reference base 1. Vertical graduation lines 21 are symmetrically distributed at both ends of the wing plate 2 along the center line 11 of the reference base 1. The top rod 3... The inner ring support roller 5 and the outer ring support roller 7 are installed between them; the total station 4 is set at the center of the ring cooler, and the total station 4 is used to measure and calibrate the installation dimensions of the inner ring support roller 5 in conjunction with the wing plate 2; the top rod 3 has right-angle notches 31 at both ends, the right-angle notches 31 form a transverse surface 311 and a longitudinal surface 322, the transverse surfaces 311 of the two right-angle notches 31 are parallel to each other, and the longitudinal surfaces 312 of the two right-angle notches 31 are located in the same plane; the top rod 3 has symmetrical horizontal engraving lines 32 in the middle, and the top rod 3 is symmetrically distributed with respect to the symmetrical horizontal engraving lines 32.

[0038] The specific installation measurement and positioning method includes the following steps:

[0039] Step S1: Establish the measurement reference for the inner ring support roller; place the reference base 1 on the top surface of the support seat 6 on the front side of the inner ring support roller 5, and align the center line of the reference base 1 with the vertical bisector of the inner ring support roller 5; regarding the vertical bisector of the inner ring support roller 5, a laser level can be used to project a vertical laser beam at the central shaft hole of the inner ring support roller 5. The projection of this laser beam onto the front side of the inner ring support roller 7 is the vertical bisector. Align the center line of the reference base 1 with the vertical bisector of the inner ring support roller 7; and press the back of the wing plate 2 against the front end face of the inner ring support roller 7. The two ends of the wing plate 2 are provided with vertical scale lines 21 symmetrically distributed with respect to the center line 11 of the reference base 1; place a spirit level on the top surface of the reference base 1, and adjust the bottom of the reference base 1 with shims until the top surface of the reference base 1 is adjusted to a horizontal position.

[0040] Step S2: Adjust the axial and radial positions of the inner ring support roller 7; a prism is required for the setup of the total station 4. The prism is mounted on the mounting platform on the front side of the inner ring support roller, maintaining the same height as the wing plate 2; the prism is mounted on the mounting platform, the platform elevation is known, the prism mounting rod is telescopic and has a height scale similar to a leveling rod. By adding the elevation of the mounting platform to the scale of the prism mounting rod, the height of the prism relative to the horizontal reference plane of the ring cooler can be determined. The total station 4 is mounted on the central observation platform, which also has a known elevation, so the elevations of both the total station 4 and the prism can be determined; the total station 4's computer contains... By inputting the heights of the total station 4 and the prism, the slant distance can be automatically converted into the horizontal distance. The actual distances K between the center of the annular cooler and the two vertical scale lines 21 of the wing plate 2 are measured using the total station 4, yielding left K and right K. The axial installation position of the inner ring support roller 5 is adjusted and calibrated based on the deviations between left and right K. The lateral distance between the vertical scale lines on the left and right sides of the wing plate 3 is w, where the distance from one vertical scale line 21 to the perpendicular bisector of the inner ring support roller 5 is w / 2. The thickness of the wing plate 2 is d. Based on triangular geometry, the actual distance K1 between the front wall of the inner ring support roller 5 and the center point of the annular cooler is calculated. Then, based on the difference between the sum of K1 and d and the design dimension value R1, the vertical offset e from the center of the annular cooler to the central axis of the inner ring support roller 5 is calculated, i.e. The radial installation position of the inner ring support roller is adjusted and calibrated so that the vertical offset e is approximately 0. When adjusting the vertical offset e, care is taken to ensure that the deviations of the left K and right K are within the acceptable range. The position of the inner ring support roller 5 can be fixed once the vertical offset e and the deviations of the left K and right K meet the requirements. It should be noted that the position adjustment of the support roller is usually done by tapping to adjust the offset direction. The tapping point is determined according to the size of the left K, right K and e, and the position of the support roller is adjusted accordingly. Therefore, after each adjustment of the position of the inner ring support roller 5, the center line 11 of the reference base 2 must be realigned with the vertical bisector of the inner ring support roller 5, the top surface of the reference base 1 is adjusted to be horizontal, the back of the wing plate 2 is pressed tightly against the front end face of the inner ring support roller 5, the measurement reference is determined, and then the left K and right K are measured until the vertical offset e and the deviations of the left K and right K meet the requirements.

[0041] Step S3: Install the top rods 3; set two top rods 3, with the distance between the two transverse surfaces on each top rod 3 set to N; adjust the outer ring support roller 7 so that the two top rods 3 can just fit between the rear side wall of the inner ring support roller 5 and the front side wall of the outer ring support roller 7; the two top rods 3 are parallel to each other. To ensure that the two top rods 3 and the central axis from the inner ring support roller 5 to the outer ring support roller 7 are on the same horizontal plane, a laser level can be set on the plane beam between the inner ring support roller 5 and the outer ring support roller 7. The two horizontal laser lines emitted by the laser level pass through the central holes of the inner ring support roller 5 and the outer ring support roller 7 respectively, so that the laser level is aligned with the relative horizontal plane of the inner ring support roller 5 and the outer ring support roller 7. A horizontal laser line is projected onto the surface. Marks are set on the left and right rims of the rear side wall of the inner ring support roller 5 and the left and right rims of the front side wall of the outer ring support roller 7 according to the horizontal laser line. One of the push rods 3 is placed at the left rim mark of the two rollers, and the other push rod 3 is placed at the right rim mark of the two rollers. The two transverse surfaces 311 of the push rod 3 are respectively attached to the rear side wall of the inner ring support roller 5 and the front side wall of the outer ring support roller 7. At the same time, the longitudinal surfaces 312 of the two push rods 3 are respectively attached to the rims of the inner ring support roller 5 and the outer ring support roller 7, so that the two push rods 3 are parallel to each other and kept on the same horizontal plane as the center hole.

[0042] Step S4: Measure the axial and radial offsets of the outer ring support roller 7; use a feeler gauge to measure the gap n when the transverse surface 311 in the right angle notch 31 of the top rod 3 is in contact with the side wall of the corresponding roller body, and the gap m when the longitudinal surface 312 in the right angle notch is in contact with the rim of the corresponding roller body, and determine the axial and radial positions of the outer ring support roller 7 based on the gap measurements.

[0043] Step S5: Adjust the axial and radial positions of the outer ring support roller 7; adjust the axial and radial positions of the outer ring support roller so that the gaps n and m between the transverse surface 311 and the longitudinal surface 312 on the two push rods and the corresponding roller body contact surfaces meet the process requirements, so that the central axis of the outer ring support roller 7 is aligned with the central axis of the inner ring support roller 5, and the longitudinal distance between the rear side wall of the inner ring support roller 5 and the front side wall of the outer ring support roller 7 is N, thereby completing the adjustment and calibration of the axial and radial installation positions of the outer ring support roller 7;

[0044] Step S6: Obtain the positioning reference of the rotary frame trolley; the rotary frame trolley is set on the inner ring support roller 5 and the outer ring support roller 7, and the distance between the center of the ring cooler and the center line of the rotary frame trolley is set as R0, which is located at the center of the central axis of the inner ring support roller 5 and the outer ring support roller 7; obtain the R0 reference point according to the position of the inner ring support roller 5 and the outer ring support roller 7 to the center of the ring cooler, so as to facilitate the subsequent installation and positioning of the rotary frame trolley. Specifically, the laser level is adjusted so that the longitudinal horizontal laser line projected by the laser level is simultaneously aligned with the central axis of the inner ring support roller 5 and the central axis of the outer ring support roller 7, and the transverse horizontal laser line projected by the laser level is simultaneously aligned with the symmetrical transverse engraving line 32 of the two top rods 3. Finally, the longitudinal and transverse horizontal laser lines projected by the laser level intersect and fall on the plane beam between the inner ring support roller 5 and the outer ring support roller 7 to form a cross line. The intersection of the cross line is the location of R0 on the plane beam used to install the support rollers, thereby obtaining the beam surface R0 reference point on the plane beam.

[0045] Step S7: According to steps 1 to 6, measure and position all inner ring support rollers 5 from the center of the ring cooler, and accurately adjust the position of the corresponding outer ring support rollers 7 according to the inner ring support rollers 5.

[0046] The measurement and positioning method of this invention adopts a symmetrical wing plate structure. A new measurement benchmark for the inner ring support roller 5 is established through the reference base 1 and the wing plate 2. This solves the technical problems of inconvenient observation, complicated procedures, and low measurement accuracy caused by the obstruction of the line of sight of the inner ring column in the traditional installation scheme. The total station set up in the center of the ring cooler can avoid the obstruction of the line of sight of the inner ring column and directly observe the symmetrical vertical engraving line 21 of the wing plate. It can transform the indirect observation of the traditional measurement method into direct visual observation, and make some items that cannot be detected directly measurable. With this invention, a circumferential measurement can be performed directly from the central measuring platform, measuring all the inner ring support rollers 5 at once, and accurately adjusting the outer ring support roller 7 according to the inner ring support rollers 5. The detection is intuitive and convenient, the detection efficiency is greatly improved, and higher reliability and accuracy can be guaranteed.

5. The method for measuring and positioning the support roller of a ring-type cooler according to claim 1, characterized in that, In step S3, a laser level is installed on the planar beam between the inner and outer ring support rollers. Two horizontal laser lines emitted by the laser level pass through the center holes of the inner and outer ring support rollers, respectively, so that the laser level projects horizontal laser lines on the opposite surfaces of the inner and outer ring support rollers. Marks are set on the left and right rims of the rear side wall of the inner ring support roller and the left and right rims of the front side wall of the outer ring support roller according to the horizontal laser lines. One of the push rods is placed at the left rim mark of the support roller, and the other push rod is placed at the right rim mark of the two rollers, so that the two transverse surfaces of the push rods are in contact with the rear side wall of the inner ring support roller and the front side wall of the outer ring support roller, respectively. At the same time, the longitudinal surfaces of the two push rods are in contact with the rims of the inner and outer ring support rollers, respectively, so that the two push rods are parallel to each other and kept on the same horizontal plane as the center hole.
