Description

Technical Field

[0001] The invention relates to the technical field of annular cooler support roller installation, and in particular to an annular cooler support roller positioning method. Background Art

[0002] The ring cooler is a device used to cool the finished sintered ore in the sintering process. It is an indispensable and important equipment in the entire sintering process. Its stable operation is the guarantee for the smooth production of the entire production line. The structure of the mainstream ring cooler today includes the following parts: transmission device, rotating part, support roller, side roller, pressure rail, frame, feed hopper, cover, unloading safety device (trolley buffer), bellows, unloading hopper, unloading area cover, double-layer ash unloading valve, unloading chute, etc. The operating principle is that the rotating part is placed on the support rollers evenly distributed around the circle, and the driving device drives the entire equipment to rotate on the support rollers through pin gear transmission. The inner ring side roller ensures that the entire rotating part will not deviate. It can be seen that the accuracy of the installation position, installation elevation and installation angle of the support roller is the basic guarantee for the stable operation of the ring cooler.

[0003] At present, equipment installation teams mostly use long steel tape measures in conjunction with pay-off ropes or distance meters to measure the center position of support rollers when installing support rollers. However, in the actual installation process, the center position of the support roller is often blocked, and some are blocked by equipment racks. The more serious problem is the renovation project. Existing equipment or buildings such as fans and chimneys located in the ring cooler circle often block the position of the support roller over a large area. At this time, installation workers often rely on experience and nearby rack columns as references for measurement, so the measurement results often have large deviations.

[0004] The existing support roller installation process, whether using a theodolite, a distance meter or a total station, requires that there are no obstacles between the center point of the annular cooler and the center point of the support roller position, that is, the measured point. However, in reality, especially in a large number of annular cooler renovation projects, the surrounding environment is complex and there are too many obstacles. As a result, when measuring the support roller position, a considerable part of the support roller position cannot be directly measured, and other estimation methods are used, such as using the nearby frame column as a reference. However, the position deviation of the column itself is large, that is, the column installation accuracy is smaller than the support roller installation accuracy, that is, the reference point position is not accurate enough, and the measurement result often has a very large deviation. Summary of the invention

[0005] In view of this, an embodiment of the present invention provides a method for positioning a support roller of an annular cooler, which is mainly used to solve the problem of large deviation of the support roller installation positioning point in an obstructed position.

[0048] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation method, structure, characteristics and effects of a ring cooler support roller positioning method proposed in accordance with the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0049] On the one hand, if Figure 4As shown, an embodiment of the present invention provides a method for positioning a support roller of an annular cooler, which is used for an annular cooler, wherein the annular cooler includes a plurality of frames, and the frames are used to connect the support rollers. More specifically, any frame includes a column (111) and a radial beam (112). The column (111) connects the bearing surface and the radial beam (112), and the column (111) is used to support the radial beam (112), and the bearing surface can be the ground. The annular cooler has an annular cooler center point O, which is the basic point when the annular cooler is installed, and the point can be an auxiliary marking point on an observation platform made on the ground. The plurality of frames are evenly arranged around the center point O of the annular cooler, and the outer contour of the radial beam (112) is approximately a cuboid, extending in a direction away from the center point O of the annular cooler, or extending in the radial direction of a circle centered on the center point O of the annular cooler. The support roller can include an inner ring support roller and an outer ring support roller, and any frame is connected with an inner ring support roller and an outer ring support roller, and the inner ring support roller is located between the center point O of the annular cooler and the outer ring support roller. The distance between the inner ring support roller and the center point O of the ring cooler is r, and the distance between the outer ring support roller and the center point O of the ring cooler is R. It can be understood that the most ideal installation result is that the inner ring support rollers are evenly distributed on the circumference of the circle with the center point O of the ring cooler as the center and the radius r, and the outer ring support rollers are evenly distributed on the circumference of the circle with the center point O of the ring cooler as the center and the radius R. On the design drawing of the ring cooler, the radius r corresponding to the inner ring support roller, the radius R corresponding to the outer ring support roller, and the unit angle α of adjacent support rollers are known. It is worth noting that the angle here and the first angle and the second angle mentioned below are all the angles between the lines from the center point of the support roller to the center point O of the ring cooler in theory. The present application aims to propose a method for accurately determining the position of each support roller based on known conditions to guide the installation of the support roller. In the following embodiments, for the convenience of explanation, the measurement or marking of the inner ring support roller is taken as an example, and the outer ring support roller has the same principle. In the following text, the position of the support roller refers to the center position of the support roller when it is installed, or it can also be the position of a certain reference point agreed upon on the support roller, that is, when the support roller is installed, the center point of the support roller or the reference point agreed upon by the support roller can be installed corresponding to the marked installation point.

[0050] More specifically, the multiple racks include a first rack (110), a second rack (120) and a current rack (130). The first rack (110), the second rack (120) and the current rack (130) have the same structure and all include the aforementioned columns (111) and radial beams (112), which will not be described in detail. Figure 1In the embodiment, except for the first frame (110), the radial beam (112) is omitted in the second frame (120) and the current frame (130). The plurality of support rollers include a first support roller (210), a second support roller (220) and a current support roller (230). The first frame (110) is used to install the first support roller (210), the second frame (120) is used to install the second support roller (220), and the current frame (130) is used to install the current support roller (230). The first support roller (210) and the second support roller (220) are two support rollers adjacent to the current support roller (230) in the circumferential direction, and there is a shielding object (300) such as a fan and a chimney between the current support roller (230) and the center point O of the annular cooler.

[0051] Methods include:

[0052] S1. Determine a first mounting point A of a first supporting roller (210) adjacent to a current supporting roller (230) that is blocked.

[0053] The first mounting point A may be the center point of the first support roller (210). Specifically, the method for determining the first mounting point A may be to use a measuring tool to mark the first mounting point A on the first frame (110) based on the center point O of the annular cooler and the radius r of the support roller. The measuring tool may be at least one of a theodolite, a steel wire, and a ruler, which will not be described in detail below. If a theodolite is used, the theodolite is placed at the center point O of the annular cooler, and a first reference arc is marked on the first frame (110) with the radius r of the support roller as the radius. In specific operations, multiple points at a distance r from the center point O of the annular cooler to the radius of the support roller may be marked on the first frame (110), and then multiple points may be connected to form a first reference arc. Alternatively, a steel ruler may be used to pull a steel ruler with a length of the radius r of the support roller, one end of the steel ruler is fixed to the center point O of the annular cooler, and multiple points are marked on the first frame (110) with the other end of the steel ruler as the reference to form a first reference arc. The center position of the first reference arc is marked as the first mounting point A. The center position refers to the intersection of the first reference arc and the center line of the radial beam (112) in the circumferential direction. The center line of the radial beam (112) can be measured and drawn, or when the radial beam (112) is processed, the center line of the radial beam (112) has a processing mark, or the center point of the first reference arc can be determined using a ruler or the like.

[0054] S2. Determine a second mounting point B of a second supporting roller (220) adjacent to the blocked current supporting roller (230).

[0055] The second mounting point B may be the center point of the second support roller (220). Specifically, the second mounting point B may be marked on the second frame (120) using a measuring tool based on the center point O of the annular cooler, the radius r of the support roller and the first mounting point A. The second mounting point B is determined based on the first mounting point A, so that even if there is an error in the first mounting point A, such as an error in finding the center position of the first reference arc, the second mounting point B may have an error equal to that of the first mounting point A in the circumferential direction on the radius r, thereby improving the accuracy of the spacing of the support rollers and reducing the influence of the circumferential positioning error. In a more specific implementation, the theodolite may be placed at the center point O of the annular cooler, and the second reference arc may be marked on the second frame (120) with the radius r of the support roller as the radius. In specific operation, multiple points at a distance r from the center point O of the annular cooler may be marked on the second frame (120), and then multiple points may be connected to form the second reference arc. Alternatively, a steel ruler may be used, and a steel ruler with a length of radius r of the support roller may be pulled, one end of the steel ruler may be fixed at the center point O of the annular cooler, and multiple points may be marked on the second frame (120) based on the other end of the steel ruler, and a second reference arc may be formed. According to the second reference arc and the first angle between the second support roller (220) and the first support roller (210), the second installation point B may be determined on the second reference arc. Since the first support roller (210) and the second support roller (220) are separated by the current support roller (230), the first angle is twice the unit angle α of the adjacent support rollers, that is, the first angle is 2α. The first angle is the angle between the line connecting the first support roller (210) and the center point O of the annular cooler and the line connecting the second support roller (220) and the center point O of the annular cooler in theory. Using a theodolite, a line 0B' is made at the first angle according to the line 0A connecting the first installation point A and the center point O of the annular cooler, and the intersection of the line 0B' and the second reference arc is the second installation point B.

[0056] It is worth noting that, if there is no current support roller (230), or when determining the position of the third support roller (240) adjacent to the first support roller (210), the aforementioned method can also be used. For example, for the third support roller (240) adjacent to the first support roller (210), a reference arc is drawn on the third frame (140) corresponding to the third support roller (240), and the third mounting point D is found on the reference arc. The line 0D connecting the third mounting point D and the center point O of the annular cooler is separated from the line 0A connecting the first mounting point A and the center point O of the annular cooler by a unit angle α of the adjacent support roller. By analogy, all mounting points of the support rollers can be measured.

[0057] S3. Determine the current installation point C of the current support roller (230) according to the first installation point A and the second installation point B.

[0058] The current installation point C may be the center point of the current support roller (230). Specifically, step S3 further includes: S3.1 calculating a first spacing L between adjacent support rollers. The first spacing L is determined according to a second angle between adjacent support rollers and a radius of the support rollers. The second angle is a unit angle α between adjacent support rollers, and the radius of the support roller is r, then L=2×r×sin(α / 2).

[0059] S3.2 Use a measuring tool to mark a third reference arc on the current rack (130) based on the first mounting point A and the first spacing L. If a theodolite is used, place the theodolite at the first mounting point A, and mark the third reference arc on the current rack (130) with the first spacing L as the radius. In specific operations, multiple points at a distance of the first spacing L from the first mounting point A can be marked on the current rack (130), and then multiple points can be connected to form the third reference arc. Alternatively, a steel ruler can be used, with a steel ruler of the length of the first spacing L, one end of the steel ruler fixed to the first mounting point A, and multiple points can be marked on the current rack (130) with the other end of the steel ruler as the reference to form the third reference arc.

[0060] S3.3 Using a measuring tool, mark a fourth reference arc on the current rack (130) based on the second mounting point B and the first spacing L. The method is similar to that of the third reference arc and will not be described in detail here.

[0061] S3.4 The intersection of the third reference arc and the fourth reference arc is taken as the current installation point C. The third reference arc and the fourth reference arc are arcs with the first installation point A and the second installation point B as the center and the first spacing L as the radius. The third reference arc and the fourth reference arc will have an intersection on the current frame (130), which is the current installation point C. For all the blocked support rollers, the above-mentioned method can be used in turn to measure the installation points.

[0062] A method for positioning the support roller of a ring cooler proposed in an embodiment of the present invention mainly determines the installation positions of two support rollers adjacent to the current support roller being blocked, namely, the first support roller and the second support roller, and determines the position of the current support roller based on the installation position of the first support roller and the installation position of the second support roller, thereby avoiding the problem of using on-site fixed objects as reference points when measuring the position of the support roller in the prior art, and the position deviation of the fixed objects leading to large deviation of the support roller position. This application uses the measured position of the support roller as a reference to ensure that the position of the blocked support roller is accurately marked, the support roller is accurately installed, and the ring cooler is smoothly operated. At the same time, the marking process can be achieved using only conventional measuring tools, which is low-cost and easy to operate.

[0063] The above implementation method can be used for the measurement of new construction projects, but in more renovation projects, there will be a gap between the observation point and the measured point. Figure 2The upper column (400) is installed after the support roller is installed in the new construction project. Therefore, the new construction project is not involved. The upper column (400) will affect the measurement and drawing of the first reference arc and the second reference arc. To solve the above problem, the following method can be used:

[0064] The frame includes a support body and an extension plate (113), the support body includes the aforementioned column (111) and a radial beam (112), the extension plate (113) is connected to the radial beam (112), the extension plate (113) is used to connect the support roller, and the extension range of the extension plate (113) at least in the circumferential direction around the center point O of the annular cooler is greater than that of the radial beam (112), that is, the width of the extension plate (113) exceeds the two sides of the radial beam (112), and the two sides of the width of the extension plate (113) can be observed at the center point O of the annular cooler. The annular cooler also includes an auxiliary plate (500), the auxiliary plate (500) includes an arc edge with a radius equal to the radius r of the support roller, if the auxiliary plate (500) is an arc plate, the outer side surface of the auxiliary plate (500) is an arc surface of the radius r of the support roller.

[0065] The aforementioned step S1, determining the first mounting point A of the first support roller (210) adjacent to the blocked current support roller (230) comprises: Figure 3 As shown, S1.1, using a measuring tool, based on the center point O of the annular cooler and the radius r of the support roller, mark a first reference point M on the first side edge of the circumference of the extension plate (113) corresponding to the first support roller (210), and mark a second reference point N on the second side edge of the circumference of the extension plate (113) corresponding to the first support roller (210). For example, the first reference point M and the second reference point N within the visible range of the extension plate (113) can be measured using a theodolite.

[0066] S1.2, use the arc edge of the auxiliary plate (500) to correspond to the first reference point M and the second reference point N. Figure 3 As shown, the arc edge is pressed onto the first reference point M and the second reference point N.

[0067] S1.3. Based on the arc edge, a fifth reference arc line is marked on the extension plate (113) corresponding to the first support roller (210). Specifically, a line is drawn on the extension plate (113) along the arc edge.

[0068] S1.4. Mark the center point of the fifth reference arc as the first installation point A.

[0069] Corresponding to step S2, determining the second mounting point B of the second supporting roller (220) adjacent to the blocked current supporting roller (230) includes:

[0070] S2.1 Use a measuring tool to mark a third reference point on the first side edge of the circumference of the extension plate (113) corresponding to the second support roller (220) based on the center point O of the annular cooler and the radius r of the support roller, and mark a fourth reference point on the second side edge of the circumference of the extension plate (113) corresponding to the second support roller (220).

[0071] S2.2 using the arc edge of the auxiliary plate (500) to correspond to the third reference point and the fourth reference point;

[0072] S2.3 marking a sixth reference arc line on the extension plate (113) corresponding to the second frame (120) based on the arc edge;

[0073] S2.4 calculates a second distance between the first support roller (210) and the second support roller (220).

[0074] S2.5 Using a measuring tool, based on the first mounting point A and the second spacing, mark a seventh reference arc on the extension plate (113) corresponding to the second rack (120).

[0075] S2.6 The intersection of the sixth reference arc and the seventh reference arc is used as the second installation point B.

[0076] Due to observation limitations, it is not possible to determine the second mounting point B on the second reference arc by observing the first angle between the second support roller (220) and the first support roller (210) as in the aforementioned embodiment. Therefore, the second mounting point B is found by drawing an arc with the first mounting point A as the center. The second spacing = 2×r×sinα. This solves the problem of the radial beam (112) being blocked and the arc not being directly drawn on the radial beam (112). The first mounting point A and the second mounting point B are determined. After that, the current mounting point C can be determined based on the first mounting point A and the second mounting point B according to the aforementioned embodiment.

[0077] In one implementation, the method further includes: S4, verifying whether the distance between the current installation point and the first installation point A and the second installation point B is the first distance L.

[0078] After determining the current installation point C, the position of the current installation point C may be deviated due to errors in the process of drawing the third reference arc and the fourth reference arc. The position of the current installation point C can be verified, that is, directly using a measuring tool to measure whether the distance between the first installation point A and the current installation point C, and the distance between the second installation point B and the current installation point C are the first spacing L. If so, confirm that the current installation point C is valid. Otherwise, repeat step S3 to re-measure the current installation point C.

[0079] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
