Description

Technical Field

[0001] The invention relates to the technical field of sintering ring coolers, and in particular to a wire drawing measurement method for installing a supporting roller of a sintering ring cooler. Background Art

[0002] The multifunctional blast ring cooler (hereinafter referred to as the ring cooler) is one of the most important equipment in the sintering production process. Today, with the large-scale ring cooler equipment, the ring cooler must be assembled and debugged on site. The quality of its on-site installation is directly related to the operating performance and service life of the ring cooler equipment. During the operation of the ring cooler, a number of rotating frame trolleys connected to form a circular motion are used to support the hot ore. The blowers evenly distributed on the periphery of the ring cooler blow out cold air from the lower half of the rotating frame trolley through the hot material layer to exchange heat, and use the exhaust gas to take away the heat to achieve the cooling of the hot sintered ore. Therefore, the stable operation of the rotating frame is crucial to the ring cooler. The support roller is the basis for supporting the rotating frame trolley to achieve circular motion. At the same time, the support roller is prone to failure in daily operation. The deviation of the ring cooler support roller from the rotating frame trolley track will cause axial load. The failure rate of the support roller under comprehensive operating conditions such as dust and temperature alternation is very high, so the position and geometric dimensions of the support roller will significantly affect whether the rotating frame trolley runs off. Therefore, the installation accuracy of the support roller is directly related to its stability during operation, and further determines whether the slewing frame trolley can operate safely and smoothly in actual production operation. Multiple support rollers are installed on the upper plane of the main beam and the middle beam of the frame plane beam. There are two support rollers on each single main beam or middle beam, which are symmetrically arranged on both sides of the ring center line with the ring center line of the ring cooler. Several support rollers are combined to form two support rings located on both sides of the ring center line for supporting the rotating body. In the ring cooler, there are inner ring columns for installing components such as plane beams and side rollers, and inner ring columns for setting up waste heat recovery wind and smoke ducts. The inner ring columns will block the line of sight of the total station type electronic rangefinder (hereinafter referred to as the total station) installed on the central measuring platform. At the same time, the inner ring support rollers also block the outer ring support rollers. Only indirect measurement can be performed during measurement, which brings great inconvenience to the installation and measurement of the support rollers.

[0003] In the process of implementing the present invention, the applicant discovered that there are at least the following problems in the prior art:

[0004] The sight line of the total station electronic distance meter is blocked by the inner ring column and the inner ring support roller, which makes the installation and positioning of the support roller difficult. Summary of the invention

[0005] The embodiment of the present invention provides a wire drawing measurement method for installing a support roller of a sintering ring cooler, so as to solve the problem that the sight line of a total station type electronic distance meter is blocked by an inner ring column and an inner ring support roller, resulting in difficulty in installing and positioning the support roller.

The measurement is intuitive and convenient, and the installation efficiency is greatly improved.

[0168] Further, there are one or more supporting rollers to be installed between the actual position of the left supporting roller and the actual position of the right supporting roller.

[0169] In some embodiments, Figure 3 As shown, there is only one shielded support roller 7 to be installed between the left support roller 8 and the right support roller 9. Figure 4 As shown, there are multiple shielded support rollers 7 to be installed between the left support roller 8 and the right support roller 9. For each support roller to be installed, a pull wire 10 is set using the method of the embodiment of the present invention for installation. The embodiment of the present invention can support the installation of multiple support rollers to be installed based on the same method steps.

[0170] The above technical solution of the embodiment of the present invention is described in detail below in conjunction with specific application examples. For technical details not introduced during the implementation process, please refer to the relevant description in the previous text.

[0171] like Figure 5 , Figure 6 ,and Figure 7The figure shows the layout of the support rollers of the ring cooler and the position of the inner ring columns; 100 support rollers 11 are respectively installed on the upper planes of the main beam and the middle beam 13 of the frame plane beam 12. There are two support rollers 11 on each single main beam or middle beam 13, which are symmetrically arranged on both sides of the ring center line 14 of the ring cooler. Several support rollers 11 are combined to form two support rings located on both sides of the ring center line 14 for supporting the rotating body. In the ring cooler, there are inner ring columns 15 for installing components such as plane beams and side rollers, and inner ring columns 15 for setting up waste heat recovery wind and smoke ducts. The inner ring columns 15 will block the line of sight of the total station type electronic rangefinder (hereinafter referred to as the total station) set up on the central measuring platform 16. At the same time, the support rollers of the inner ring also block the outer ring support rollers. Only indirect measurement can be performed during measurement, which brings great inconvenience to the installation and measurement of the support rollers. Therefore, it is urgent to improve the installation project of the support rollers.

[0172] The embodiment of the present invention mainly solves the problem that when using a total station to measure and install the support rollers of the ring cooler, a single support roller is blocked by the inner ring column, or multiple continuous support rollers are blocked by the inner ring column and cannot be measured. The embodiment of the present invention provides a method for quickly and conveniently measuring the installation position during the installation of the support rollers of the ring cooler, and uses the support rollers that have completed the installation measurement to assist in the installation of the blocked support rollers. The embodiment of the present invention is simple and easy to operate, and can be measured during on-site construction, which improves the measurement efficiency. There is no need to measure the angle, only the length of the line segment needs to be measured, which effectively improves the speed and ease of support roller installation measurement and can meet the needs of on-site use.

[0173] In the actual installation process of the ring cooler support roller, the actual installation position of the support roller deviates from the theoretical design installation position due to factors such as measurement accuracy and installation process. The embodiment of the present invention can calculate the position data of the blocked support roller and the length of each section of the wire in the installation technical step of the wire measurement method according to the actual position of the unblocked support rollers on the left and right sides of the inner ring column through the calculation formula provided by the embodiment of the present invention, and adjust the support roller to be installed blocked by the inner ring column to the designed installation position.

[0174] According to the distance between the center point of the ring cooler and the leftmost end of the front side surface of the support roller at the actual position measurable on the left, the distance between the center point of the ring cooler and the rightmost end of the front side surface of the support roller at the actual position measurable on the right, the distance between the leftmost end of the front side surface of the support roller at the actual position measurable on the left and the rightmost end of the front side surface of the support roller at the actual position measurable on the right, the axial deviation and radial deviation of the actual installation position of the support roller measurable on the left, and the axial deviation and radial deviation of the actual installation position of the support roller measurable on the right, the length of each section of the wire drawing in the installation technical step of the wire drawing measurement method is calculated by the calculation formula provided in the embodiment of the present invention, and the support roller to be installed blocked by the inner ring column is adjusted to the designed installation position.

[0175] The specific method is as follows:

[0176] Step S1: Use a total station mounted on the central measuring platform of the annular cooler to measure the unobstructed measurable support rollers on the left and right sides of the support rollers blocked by the inner ring columns, measure the axial deviation and radial deviation of their installation, and establish a coordinate system at the designed installation position of the support rollers to be installed and perform a series of calculations.

[0177] Preferably, if Figure 2 As shown, let the center point of the ring cooler be O (the origin of the coordinate system; establish a coordinate system, the line connecting the center point B of the front side of the roller body at the (designed) theoretical installation position of the support roller to be installed and point O (the origin of the coordinate system) is the Y axis, and the horizontal line passing through the center point B of the front side of the roller body at the design theoretical installation position of the support roller to be installed and parallel to the front side of the roller body at the design theoretical installation position of the support roller to be installed is the X axis; the inherent dimensions of the support roller include: wheel width W (equivalent to the outer diameter) and wheel thickness M; the theoretical position of the roller body center point of the left support roller is A, and the theoretical position of the roller body center point of the right support roller is C. ∠AOB=a, ∠COB=β; wherein, the values ​​of ∠AOB and ∠COB can be obtained from the design drawing of the annular cooler.

[0178] According to the actual measurement data, the axial deviation of the left support roller is Ah, and the radial deviation is At; the axial deviation of the right support roller is Ch, and the radial deviation is Ct;

[0179] According to the actual deviations of the left support roller and the right support roller, the actual position of the center point of the roller body of the left support roller is set to A', and the actual position of the center point of the roller body of the right support roller is set to C'; the inherent dimensions of the support rollers include the wheel width W and the wheel thickness M; the leftmost end of the front side of the actual position roller body of the left support roller is A'j, and the rightmost end of the front side of the actual position roller body of the right support roller is C'q; the deviation between the theoretical position of the roller body center point of the left support roller A and the actual position A' in the X-axis direction is recorded as the X-axis deviation of the left support roller Ak, and the deviation between the theoretical position of the roller body center point of the left support roller A and the actual position A' in the Y-axis direction is recorded as the Y-axis deviation of the left support roller Ae; the deviation between the theoretical position of the roller body center point of the right support roller C and the actual position C' in the X-axis direction is recorded as the X-axis deviation of the right support roller Ck, and the deviation between the theoretical position of the roller body center point of the right support roller C and the actual position C' in the Y-axis direction is recorded as the Y-axis deviation of the right support roller Ce;

[0180] The positive direction of the X-axis points to the right, and the positive direction of the Y-axis points upward; the X-axis deviation is negative to the left and positive to the right; the Y-axis deviation is positive upward and negative downward.

[0181] like Figure 8 and Fig. 9 , calculated based on the trigonometric relationship:

[0182] Ak=At·cosa-Ah·sina (16)

[0183] Ae=At·sina+Ah·cosa (17)

[0184] Ck=Ct·cosβ+Ch·sinβ (18)

[0185] Ce=Ch·cosβ-Ct·sinβ (19)

[0186] According to the trigonometric relationship, we can calculate:

[0187]

[0188] We get formula (7).

[0189] Step S2: Use a total station mounted on the central measuring platform of the annular cooler to measure the distance between the center point of the annular cooler and the leftmost end of the front side surface of the roller body of the actual position of the left support roller, and the distance between the center point of the annular cooler and the rightmost end of the front side surface of the roller body of the actual position of the right support roller. Pull a line between the leftmost end of the front side surface of the roller body of the actual position of the left support roller and the rightmost end of the front side surface of the roller body of the actual position of the right support roller and measure its length. Then, through a series of calculations, the length of the line between the leftmost end of the front side surface of the roller body of the support roller to be installed and the leftmost end of the front side surface of the roller body of the actual position of the left support roller, and the length of the line between the rightmost end of the front side surface of the roller body of the support roller to be installed and the rightmost end of the front side surface of the roller body of the actual position of the right support roller are obtained, and the position of the support roller to be installed is adjusted according to the calculated data.

[0190] Preferably, the distance L between the center point O of the ring cooler and the rightmost end C′q of the front side of the right support roller is OC，q , which can be measured by the total station installed on the measuring platform at the center of the ring cooler.

[0191] like Figure 2 As shown, let ∠C′OC′q be θ, and according to the trigonometric function relationship, we get formula (8);

[0192] Assume ∠BOC′ is β′, and the following formula is obtained based on the trigonometric function relationship:

[0193]

[0194] Taking the arc cosine of formula (21), we get formula (9);

[0195] Where: OC is the radius R of the theoretical position of the support roller; From the design diagram, we know that ∠COB = β; From formula (7), we know that L OC′ ; From formula (18) and formula (19), or through actual measurement, it can be known that the X-axis deviation of the right support roller is Ck and the Y-axis deviation is Ce.

[0196] Based on formula (8) and formula (9), we can get formula (10);

[0197] Similarly, let ∠A′jOA′ be ∠A′OB is a′, and formulas (2), (3), (4) and (5) can be obtained; where L is the distance between the center point O of the annular cooler and the leftmost end A′j of the front side of the roller body at the actual position of the left support roller. OA′j , which can be measured by the total station installed on the measuring platform at the center of the ring cooler.

[0198] A line L is drawn between the leftmost end A′j of the front side of the roller body at the actual position of the left support roller and the rightmost end C′q of the front side of the roller body at the actual position of the right support roller. A′jC′qAnd measure the length of the wire. According to the triangle cosine theorem, we can get formula (1);

[0199] According to the trigonometric relationship, we can calculate:

[0200] Where ∠OB′A′j=π-∠OA′jC′q-∠A′jOB (22)

[0201] like Figure 2 , as shown, according to the sine theorem:

[0202]

[0203] Right now:

[0204] According to formula (22) and formula (24), we get formula (6);

[0205] Similarly, we can know:

[0206] According to formula (25), formula (11) can be obtained;

[0208] According to formula (23) the sine theorem we get:

[0209]

[0210] Known get:

[0211] BB′=OB-OB′ (27)

[0212] According to formula (23), formula (26) and formula (27), formula (12) is obtained;

Since the drawing line may not be parallel to the front side surface of the roller body at the design theoretical installation position of the support roller to be installed, the distances between the left end, center point and right end of the front side surface of the roller body of the support roller to be installed and the drawing line are different, and the distances need to be calculated separately, and the position of the support roller to be installed along the positive direction of the Y axis is adjusted according to the calculated distance.

[0214] Preferably, the pull line L A′jC′q The projection extension line of intersects the straight line in the X-axis direction passing through point B at point N. Let the endpoint of the front side surface of the roller body at the design theoretical installation position of the support roller to be installed close to N be Bt, and the endpoint of the front side surface of the roller body at the design theoretical installation position of the support roller to be installed away from N be By.

[0217]

[0218] According to the similar triangle theorem:

[0219]

[0220] Therefore, let the center point B of the front side of the roller body and the pull line L at the design theoretical installation position of the support roller to be installed. A′jC′q The distance between the end point Bt on the front side of the roller body near the N side of the design theoretical installation position of the support roller to be installed and the tension line L is BB′. A′jC′q The distance between the end point By on the side away from N and the tension line L is BtB′t, and the distance between the end point By on the side away from N and the front side of the roller body at the design theoretical installation position of the support roller to be installed is BtB′t. A′jC′q The distance is ByB′y, and the support roller to be installed is adjusted along the positive direction of the Y axis.

[0221] According to formula (30), we can get:

[0222]

[0223] and formula (32):

[0224]

[0225] According to formula (32), we get formula (14);
