Description

Technical Field

[0001] The present application relates to the field of sintering technology, and in particular to a device for detecting the offset and roundness of a rotating frame of a ring cooler. Background Art

[0002] The function of the ring cooler is to effectively cool the sintered hot ore unloaded from the sintering machine. Compared with the belt cooler, the ring cooler has the advantages of less floor space, less investment, and high equipment utilization. The development of the ring cooler produced by the sintering machine system is to install a ring track under the ring cooler, and the ring cooler is supported by multiple support wheels. Its operation is driven by a drive device composed of two motors, a reducer, a friction wheel and a friction plate, and is driven by friction. Due to the different friction coefficients of the support wheels, the position of the ring cooler's rotating frame will shift after the ring cooler has been running for a period of time. When the position of the ring cooler's rotating frame is diverted and shifted significantly, the track on the ring cooler will gnaw the rim of the support wheel. The consequences are that the driving force of the ring cooler becomes larger, causing the current of the driving device to overload, and the life of the support wheel and track is affected.

[0003] The rotating frame of the ring cooler is affected by the radiant heat generated by the high-temperature sintered ore on the trolley. When the track under the ring cooler bites the rim of the supporting wheel, the resistance increases, and the rim and the transmission of the ring cooler will affect the roundness of the rotating frame of the ring cooler.

[0004] The existing technology is unable to measure the position offset of the annular cooler online, especially the change in the roundness of the rotating frame, which is not conducive to the subsequent precise adjustment of the position and roundness of the rotating frame.

[0005] Therefore, we propose a ring cooler rotating frame offset and roundness detection device to solve the above problems. Utility Model Content

[0025] The technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0026] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The present application provides a ring cooler rotary frame offset and roundness detection device, comprising a rotary frame 8 mounted on the ring cooler and a detection mechanism arranged on one side of the rotary frame 8, wherein:

[0027] The detection mechanism includes several digital magnetic license plates 1, three digital distance measuring sensors 2, a bracket 4, a magnetic induction device 5, a high-definition license plate recognition camera 6 and two brackets 2 7. The several digital magnetic license plates 1 are fixedly mounted on the outer wall of the rotating frame 8 and are evenly distributed. The bracket 1 4 and the two brackets 2 7 are equidistantly distributed outside the rotating frame 8 relative to the center of the rotating frame 8. The three digital distance measuring sensors 2 are respectively fixedly mounted on the bracket 1 4 and the two brackets 2 7. The digital distance measuring sensor 2 is used to measure the distance from the digital distance measuring sensor to the outer wall of the rotating frame. The magnetic induction device 5 and the high-definition license plate recognition camera 6 are fixedly mounted on the bracket 1 4. The magnetic induction device 5 and the high-definition license plate recognition camera 6 are electrically connected. The several digital magnetic license plates 1 installed on the outside of the rotating frame 8 pass through and trigger the magnetic induction device 5. The magnetic induction device 5 sends a measurement signal to the three digital distance measuring sensors 2. The digital distance measuring sensors 2 perform distance measurement. The high-definition license plate recognition camera 6 simultaneously shoots several digital magnetic license plates 1 and converts them into numbers.

[0028] In this embodiment, the number of the digital magnetic license plates 1 is not less than 20. It should be additionally explained that a plurality of digital magnetic license plates 1 can be fixed on the outer side wall of the revolving frame 8 by pasting.

[0029] In this embodiment, Figure 2 As shown, the number of digital magnetic license plate 1 attached to the rotating frame 8 is one, and the digital magnetic license plate 1 cooperates with the magnetic induction device 5 to control two digital distance measuring sensors 2 with an angle of 90° to measure the offset of the rotating frame 8 in the vertical direction, as shown in FIG. Figure 3 As shown, there are 19 digital magnetic license plates 1 pasted on the revolving frame 8, and they are evenly distributed on the semicircle outside the revolving frame 8, and the spacing between adjacent digital magnetic license plates 1 is 10°, and the numbering ranges from 0 to 18, totaling 180°.

[0030] In this embodiment, the three digital distance measuring sensors 2 are collinear with the center of the revolving frame 8 , and the angle between two adjacent digital distance measuring sensors 2 is set to 90°.

[0031] In this embodiment, the three digital distance measuring sensors 2, the magnetic induction device 5 and the high-definition license plate recognition camera 6 are located on the same horizontal plane.

[0032] In this embodiment, the magnetic induction device 5 is a magnetic induction switch or a proximity switch.

[0033] In this embodiment, the detection mechanism also includes a digital processor 3, which is fixedly mounted on a bracket 4. The three digital distance sensors 2 are electrically connected to the digital processor 3 for receiving and storing the distance information sent by each digital distance sensor 2 and performing calculations.

[0034] In this embodiment, the digital processor 3 is a single chip microcomputer, which has the function of converting pictures into text. The single chip microcomputer can determine the offset distance and orientation of the rotating frame 8 and the change in the roundness of the rotating frame 8 through calculation and comparison. When several digital magnetic license plates 1 trigger the magnetic induction device 5 respectively, the two digital distance measuring sensors 2 corresponding to the center of the rotating frame 8 measure the distance accordingly. The change in this measured value is the change in the diameter of the rotating frame 8, that is, the change in the roundness of the rotating frame 8.

[0035] The digital processor 3 is equipped with a data display unit, which is used to display the design center and offset position of the revolving frame 8, and can intuitively reflect the change of roundness. The data display unit can be used to display the displacement of the revolving frame 8 in the vertical direction and the distance from the center position (such as Figure 4 The maximum and minimum diameters of the ellipse and their relative positions can also be displayed.

[0036] The working principle of the ring cooler rotary frame offset and roundness detection device provided by the present application is described in detail below through specific embodiments:

[0037] Measurement of the offset of the rotating frame 8: A digital magnetic license plate 1 with a number 20 is pasted on the rotating frame 8 of the ring cooler. When the digital magnetic license plate 1 with a number 20 passes by and triggers the magnetic induction device 5, the signal of the magnetic induction device 5 is transmitted to the high-definition license plate recognition camera 6. The high-definition license plate recognition camera 6 transmits the image to the digital processor 3, allowing the two mutually perpendicular digital distance measuring sensors 2 to measure and record data at the same time; in this way, a set of data is measured every time the ring cooler rotates one circle.

[0038] The measured data is transmitted to the digital processor 3 through the data line for processing. Figure 4 , according to the detection and processing requirements, the deviation of the rotating frame in the corresponding direction and the change of the rotating frame offset are calculated respectively.

[0039] Displacements in the vertical direction are recorded as X and Y, respectively, and deviations in the opposite direction are negative;

[0040] The distance of the revolving frame offset is

[0041] The angle of the slewing frame offset is According to the positive and negative values ​​of X and Y, the angle limits can be determined (X positive Y positive first phase limit, X negative Y positive second phase limit, X negative Y negative third phase limit, X positive Y negative fourth phase limit);

[0042] Define the installation center point as 0,0; the straight line connecting X, Y to 0,0 is the position diagram of the deviated rotation frame center;

[0043] Measurement of the roundness of the rotating frame: stick the digital magnetic plates 1 numbered 0-19 on the outside of the rotating frame 8 of the ring cooler at intervals of 10°;

[0044] The ring cooler revolving frame 8 rotates, and the digital magnetic license plates 1 numbered 0-19 trigger the magnetic induction device 5 respectively. The signal of the magnetic induction device 5 is transmitted to the high-definition license plate recognition camera 6. The high-definition license plate recognition camera 6 takes a picture of the digital magnetic license plate 1 and transmits it to the digital processor 3. The digital processor 3 converts the picture into digital. The digital processor 3 allows the two opposite digital distance sensors 2 to measure and record data at the same time; in this way, the ring cooler measures a set of data every half turn;

[0045] In this way, while detecting the deviation of the ring cooler trolley, the change in the diameter of the rotating frame 8 can be detected; the 19 digital magnetic plates 1 are arranged at intervals of 10°, spanning half the circumference of the rotating frame 8, and can measure the maximum radius and minimum radius of the roundness change of the rotating frame 8, and accurately record the position of the change.
