[0046] In order to better assist the installation of the side roller of the ring cooler and detect the parameters of the side roller, the application provides a gauge.

[0048] As shown in the drawings, Figures 1-3 In the installation engineering of the ring cooler, the radius of the whole circle of the side roller, the installation levelness of the side roller and the installation elevation of the side roller are the necessary inspection items, and the existing side roller is basically designed as a universal standard interval, the standard size of the wheel body is 300mm in outer diameter and 150mm in thickness, thus the gauge developed and designed for the side roller of this size has a certain universality. The whole circle of the ring cooler is distributed with several side rollers, the outer circle roller surface of the side roller and the side rail of the rotary frame are designed with a certain gap, and the rotary frame is limited in the ring direction.

[0049] In the specific embodiments of the application, the specific size of the gauge proposed for the standard interval size of the side roller is fixed, but gauges of different sizes can be designed for different side rollers.

[0050] Figure 4 The overall structure diagram of the gauge proposed in the application; Figure 5 The three-dimensional view of the arc-shaped structure of the gauge proposed in the application matches the side roller of the ring cooler; Figure 6 The side view of the arc-shaped structure of the gauge proposed in the application matches the side roller of the ring cooler; Figure 7 The top view of the arc-shaped structure of the gauge proposed in the application matches the side roller of the ring cooler.

[0051] As shown in the drawings, Figures 4-6 The gauge proposed in the application comprises an arc-shaped structure 4, a horizontal plate and a vertical plate, wherein the inner circle arc of the arc-shaped structure 4 is adapted to match the outer circle arc of the side roller 1; the horizontal plate is arranged in the horizontal direction and is provided with the vertical plate connected with the horizontal plate and perpendicular to the horizontal plate, and the vertical plate is fixedly connected to the arc-shaped structure 4; the horizontal plate is provided with a first reference surface 5, the horizontal plate is provided below with a supporting plate 8, and the first reference surface 5 is parallel to the bottom surface of the supporting plate 8; the two ends of the vertical plate are provided with a second reference surface 6 and a third reference surface 7, the second reference surface 6 and the third reference surface 7 are symmetrically arranged on the gauge 3, the first reference surface 5 is perpendicular to the second reference surface 6, and the second reference surface 6 is perpendicular to the third reference surface 7. The extension surfaces of the second reference surface 6 and the third reference surface 7 are in the same plane.

[0052] In specific embodiments, the gauge 3 is a left-right symmetrical structure, and the vertical bisector of the gauge 3 is parallel to the axis of the side roller 1.

[0053] In some embodiments, the horizontal distance between the second reference surface 6 and the third reference surface 7 is greater than the width of the inner ring column of the ring cooler. Figure 2 The horizontal distance between the second reference surface 6 and the third reference surface 7 is greater than the width of the inner ring column in the direction of rotation. In actual use, the distance from the second reference surface 6 and the third reference surface 7 to the center of the ring cooler can be measured in an unobstructed manner, bypassing the obstacle of the inner ring column, making the indirect observation of multiple measurement reference conversions into more direct visual observation, making certain undetectable items measurable, and greatly improving detection reliability and efficiency.

[0054] Through the embodiments of the present application, the arc surface of the arc structure 4 of the gauge matches the outer arc of the side roller, that is, the radius of the inner arc of the arc structure 4 is the same as the radius of the outer arc of the side roller 1, and the center of the inner arc of the arc structure 4 coincides with the center of the outer arc of the side roller 1. In this way, the vertical bisector of the gauge is parallel to the axis of the side roller, and then cooperating with the machining means, the horizontal degree of the first reference surface 5 of the gauge and the horizontal degree of the support plate can be guaranteed, and the vertical degree of the second reference surface 6 and the third reference surface 7 can be guaranteed.

[0055] In some embodiments, a magnet is arranged on the arc structure 4, which is suitable for adsorbing the inner arc of the arc structure 4 to the outer arc of the side roller 1. The magnet used in the present embodiment is a neodymium boron iron magnet. Through the limitation of the magnet and the size of the inner arc of the arc structure, it is ensured that the arc structure can be closely attached to the outer arc of the side roller. On this basis, it is ensured that the error is small when measuring other parameters.

[0056] In some embodiments, the horizontal distance from the second reference surface 6 to the center of the inner arc of the arc structure 4 is a first preset value; and the vertical distance from the upper end surface of the arc structure 4 to the bottom surface of the support plate 8 is a second preset value.

[0057] In the present embodiment, the first preset distance is 350mm; and the second preset distance is 125mm.

[0058] As Figures 1-3As shown, in some embodiments, a connecting block is arranged between the vertical plate and the arc-shaped structure 4, the vertical plate and the connecting block of the gauge 3 form a T-shaped structure, the second reference surface 6 and the third reference surface 7 are located at two symmetrical end portions of the T-shaped structure, and the arc-shaped structure 4 is located at an outwardly protruding end portion of the T-shaped structure. A connecting plate is arranged between the horizontal plate of the gauge 3 and the support plate 8, and a rib plate is arranged between the horizontal plate and the support plate 8, and a rib plate is arranged between the arc-shaped structure 4 and the connecting plate.

[0059] The gauge provided by the present application has a simple appearance, an overall aesthetic appearance and convenient use. Specific embodiment 2

[0061] The present application also provides a method for using the gauge, and the method comprises:

[0062] The inner arc of the arc-shaped structure 4 of the gauge 3 is attached to the outer arc of the side roller 1;

[0063] The support plate 8 of the gauge 3 is placed on the support roller 2 of the ring cooler;

[0064] The distances from the second reference surface 6 and the third reference surface 7 to the total station are measured by using the total station, and the positioning distribution of the side roller 1 center to the ring cooler center is obtained by combining the size of the gauge 3; wherein the total station is placed at the center of the ring cooler;

[0065] A digital inclinometer is placed on the first reference surface of the gauge 3, the inclination of the first reference surface is read by the digital inclinometer, and the levelness of the side roller 1 is obtained.

[0066] In some embodiments, the method further comprises measuring the distance from the upper end surface of the arc-shaped structure 4 of the gauge 3 to the upper end surface of the side roller 1 by using a protractor, and obtaining the actual elevation positioning error of the side roller 1 by combining the size of the gauge 3 and the design elevation h of the highest point of the side roller 1 relative to the support roller 2.

[0067] In the specific implementation process, as Figure 7 The arc-shaped structure of the gauge provided by the present application matches the side roller of the ring cooler. First, the gauge 3 is placed in the state as shown in Figure 7 The inner arc of the arc-shaped structure matches the outer arc of the side roller; and the support plate of the gauge is placed on the support roller of the ring cooler.

[0068] As shown in Figure 7As shown, the distance between the second reference surface and the third reference surface is 460 mm, and the distance from the second reference surface to the center of the side roller is 350 mm. By using the Pythagorean theorem, the theoretical value of the hypotenuse L can be calculated by combining the theoretical value of the side roller diameter R1 with the above two sizes. The total station is placed at the center of the ring cooler, and the distances from the second reference surface 6 and the third reference surface 7 to the total station are measured using the total station: Lleft and Lright. By comparing (Lleft+Lright) / 2 with the theoretical value of L, the positioning of the side roller 1 axis to the center of the ring cooler is estimated, and then the distance from the side roller to the center of the ring cooler is adjusted according to the actual comparison size.

[0069] When detecting the installation levelness of the side roller, the digital inclinometer is placed on the first reference surface of the gauge, and the inclination of the first reference surface is read by the digital inclinometer. Due to the matching of the arc-shaped structure and the side roller, the symmetrical arrangement of the gauge and the characteristics of machining ensure the size of the key geometric elements to be measured, i.e. the horizontal inclination parameter θ of the side roller 1 can be indirectly obtained from the inclination of the first reference surface.

[0070] As an alternative embodiment, when detecting the installation levelness of the side roller, a level can also be used. The level is placed on the first reference surface of the gauge.

[0071] Figure 6 A side view of an arc-shaped structure of a gauge matching the side roller of a ring cooler is provided for the present application. As shown Figure 6 When detecting the installation elevation of the side roller, the distance y from the top of the arc-shaped structure of the gauge to the top surface of the side roller is measured using a protractor, and the vertical theoretical design distance h from the center position of the side roller to the top of the supporting roller is combined with the distance 125 mm from the top of the arc-shaped structure of the gauge to the bottom of the support plate of the gauge. By using the calculation formula htheoretical+150 / 2=125+ytheoretical, the theoretical value of y is obtained, and then compared with the actual value of y to know the actual installation deviation of the side roller, and then the up and down installation position of the side roller is adjusted. Similarly, by using the inherent size 170 mm of the gauge and the calculation of the design value x, the transverse positioning of the supporting roller and the side roller can be estimated, and then the transverse distance between the side roller and the supporting roller is adjusted.

[0072] In addition to the above advantages, the present gauge also has the following advantages: compact and lightweight (weight less than 8 kg), extremely convenient and efficient operation, short time consumption for measuring each parameter, greatly improving the efficiency of traditional measurement methods, suitable for construction sites with tight schedules, and measurement work can be carried out simultaneously with construction, without affecting the construction progress of the ring cooler site.
