Description

Technical Field

[0001] This application relates to the field of industrial measurement, and particularly to a general auxiliary tool for measuring the horizontal level of a roll system. Background Art

[0002] With the increasing market competition in the steel industry, people's awareness of product quality has been continuously enhanced, and the accuracy requirements for equipment have also been continuously improved. The roll system is an indispensable equipment in each production line of hot rolling, cold rolling, and silicon steel. The roll system plays a role in transporting slab and steel strip in steel rolling, and also plays roles such as steering, strip tensioning, and controlling strip shape. If the accuracy of the roll system during installation does not meet the standard, or the original installation accuracy is lost due to wear, corrosion, etc. during long-term use, quality problems such as strip deviation, sickle bend, and coiling edge overflow will occur. Therefore, we need to regularly measure the roll system.

[0003] The development of industrial measurement technology has brought great convenience to the measurement of the spatial position accuracy of on-site equipment, and it is also the most effective means for measuring the accuracy of on-site equipment. For example, for batch detection of roll systems such as hot rolling laminar roller tables and descaling roller tables, a level is mostly used in combination with a scale for measurement. However, this method has the following problems: First, the accuracy of the level is relatively low; second, when the scale is placed, it has a line contact with the roll surface, and it is necessary to continuously adjust the scale manually to find the highest point of the roll system, which is difficult to hold steadily and has a large human error; third, when measuring, it is necessary to read the barcode on the scale, which has high requirements for light and slow reading speed each time; fourth, when using a level for measurement, it is necessary to manually copy and record the read data, and human errors such as recording errors are likely to occur. Therefore, in this high-quality requirement environment, in order to improve accuracy and efficiency during on-site measurement, high-precision instruments such as total stations are required for detection. The instrument accuracy of the total station is higher than that of the level, and at the same time, it is measured in combination with professional software and a reflector ball, and the overall measurement accuracy far exceeds the measurement accuracy of the level in combination with the scale. However, the special roll system measurement tool saddle of the total station is not as long as the scale, and during measurement, it is blocked by on-site equipment. Due to the different heights of the roll system layout or measurement positions, multiple station transfers are required for measurement, which will reduce the measurement accuracy and efficiency. At the same time, the saddle cannot compare the levelness of the roll system between rollers with different diameters. Summary of the Invention

[0004] One of the purposes of this application is to provide a general auxiliary tool for measuring the horizontal level of a roll system, aiming to improve the problem of inaccurate measurement of the existing roll system.

[0005] The technical solution of this application is as follows:

[0006] A general auxiliary tool for measuring the horizontal level of a roll system, comprising:

[0007] A measuring ruler, on which a plurality of horizontal card slots are arranged at intervals in the height direction, and a V-shaped groove is opened at the bottom of the measuring ruler, and the opening of the V-shaped groove faces away from the top of the measuring ruler;

[0008] A first horizontal bubble, the first horizontal bubble is installed on the top of the measuring ruler and is arranged along the length direction of the measuring ruler;

[0009] A placing table, the placing table is installed on the measuring ruler along a direction perpendicular to the height direction of the measuring ruler, one end is horizontally clamped in the horizontal card slot, the other end extends out of the outside of the measuring ruler, and a second horizontal bubble and a reflecting ball are installed at intervals in sequence, and the second horizontal bubble is located between the measuring ruler and the reflecting ball.

[0010] As a technical solution of the present application, an installation through hole is opened at one end of the placing table, and the placing table is sleeved in the horizontal card slot of the measuring ruler through the installation through hole.

[0011] As a technical solution of the present application, bolts are installed on both adjacent sides of the placing table, one end of the bolt penetrates into the installation through hole and is fixedly connected to the side wall of the horizontal card slot.

[0012] As a technical solution of the present application, the second horizontal bubble is arranged along the width direction of the placing table.

[0013] As a technical solution of the present application, a measuring through hole is opened at the other end of the placing table, and the reflecting ball is arranged in the measuring through hole.

[0014] As a technical solution of the present application, there are four horizontal card slots, and the distances between adjacent horizontal card slots are the same.

[0015] As a technical solution of the present application, the material of the placing table includes aluminum-magnesium alloy material.

[0016] As a technical solution of the present application, the opening angle of the V-shaped groove is 150°.

[0017] The beneficial effects of the present application:

[0018] In the general auxiliary tool for measuring the roll system level of the present application, during measurement, according to the device to be measured and the on-site measurement line of sight, select a horizontal card slot suitable for the measurement height on the measurement scale. Install the placement table into the selected horizontal card slot through the installation opening. When installing, ensure that the bottom surface of the placement table is in close contact with the upper surface of the horizontal card slot of the measurement scale. Then, rotate the fixing bolts on the adjacent sides of the placement table to fix the placement table on the measurement scale. Place the V-shaped groove at the bottom of the measurement scale along the axis direction of the roller on the roller surface. Then, adjust the measurement scale along the circumferential direction of the roller so that both the first horizontal bubble and the second horizontal bubble on the measurement scale are in the middle position. Place the reflection ball into the measurement through hole on the placement table and adjust the reflection ball to align it with the measuring instrument (such as a total station). Finally, perform data collection. This device can effectively improve the measurement accuracy and measurement efficiency of the roll system level measurement, reduce the complexity of its calculation, can quickly complete the measurement of different roll systems, improve the measurement efficiency while ensuring the measurement accuracy. At the same time, this device can also be applied to the level measurement of other equipment. In addition, this device has four horizontal card slots with different heights. Therefore, during measurement, different measurement positions can be adjusted according to the measurement line of sight, and the values between these four heights are standard values and can be directly cited during calculation, thus effectively solving the problem of occlusion of on-site equipment during measurement. Furthermore, the contact between the V-shaped groove and the roller surface is a two-line contact. Therefore, the stability of this device during measurement is much greater than the single-line contact of the level gauge scale, thus effectively reducing the human error caused by stability during the measurement process. In addition, due to the V-shaped groove design at the bottom of the measurement scale with a design angle of 150 degrees, when the diameter of the roller to be measured is known, the distance from the highest point of the roller surface of different diameter rollers to the V-shaped groove can be calculated, thereby obtaining the height difference between different diameter rollers, which has universality. And after the placement table is installed, the other end is outside the measurement scale. Therefore, the reflection ball on the placement table can be adjusted horizontally by 180 degrees, and at the same time, the direction of the entire measurement scale can also be adjusted by 180 degrees, thus finally realizing a 360-degree omnidirectional adjustment of the reflection ball horizontally. Therefore, it can greatly expand the measurement line of sight. Secondly, this device has universality, can measure roll systems with a relatively low position, has strong practicability, and a wide application range. Description of the Drawings

At the same time, a placement table 6 is installed on the measuring ruler 2, and the placement table 6 is installed on the measuring ruler 2 along a direction perpendicular to the height direction of the measuring ruler 2; one end of it is horizontally clamped in the horizontal card slot 3, and the other end extends out of the measuring ruler 2 by a certain length, and a second horizontal bubble 7 and a reflecting ball 8 are installed at intervals on the placement table 6 in sequence, and the second horizontal bubble 7 is located between the measuring ruler 2 and the reflecting ball 8.

[0036] It should be noted that in this embodiment, the overall height of the measuring ruler 2 is 1500 mm, the length is 50 mm, and the width is 25 mm. A plurality of horizontal card slots 3 are arranged at intervals from bottom to top on the measuring ruler 2. The width of the horizontal card slot 3 is 7 mm, and the slot depth is 8 mm. When the V-shaped slot 4 at its bottom contacts the roller, it is a two-line contact, so it has strong stability.

[0037] Further, in this embodiment, there are four horizontal card slots 3, and the spacing between adjacent horizontal card slots 3 is the same.

[0038] It should be noted that in this embodiment, an installation through hole 9 is provided at one end of the placement table 6. The installation through hole 9 is arranged in cooperation with the measuring ruler 2 and the horizontal card slots 3 thereon. The placement table 6 is sleeved in the horizontal card slots 3 of the measuring ruler 2 through the installation through hole 9. At the same time, M4×20 bolts 10 are installed on both adjacent sides of the placement table 6 for fixing after being adjusted in cooperation with the measuring ruler 2. One end of each of the two bolts 10 penetrates into the installation through hole 9 and abuts against the side wall of the horizontal card slot 3. Bolts 10 are not installed on the other two adjacent sides of the placement table 6. The other two adjacent sides are clamped in the horizontal card slot 3, while the two adjacent sides with bolts 10 are fixed by abutting against the two side walls of the horizontal card slot 3 through the bolts 10. Thus, the placement table 6 can be firmly installed on the measuring ruler 2 through fixation in four directions.

[0039] It should be noted that in this embodiment, the second horizontal bubble 7 is arranged on the placement table 6 along the width direction of the placement table 6. At the same time, a measurement through hole 11 is provided at the other end of the placement table 6, and the reflection ball 8 is arranged in the measurement through hole 11.

The placement table 6 can be made of aluminum-magnesium alloy material. To ensure its measurement accuracy, the perpendicularity of the machined surface of the placement table 6 is 0.05 mm, and the flatness is 0.03 mm.

[0041] It should be noted that in this embodiment, the opening angle of the V-shaped slot 4 is 150°.

[0042] The measurement steps of the roller system horizontal measurement general auxiliary tool 1 of this application are as follows:

[0043] First, during measurement, according to the device to be measured and the on-site measurement line of sight, select a horizontal card slot 3 suitable for the measurement height on the measuring ruler 2, and install the placement table 6 in the selected horizontal card slot 3 through the installation through hole 9. When installing, ensure that the lower bottom surface of the placement table 6 is in close contact with the bottom plane of the horizontal card slot 3 of the measuring ruler 2.

[0044] Second, fix the placement table 6 on the measuring ruler 2 by the fixing bolts 10 on two adjacent sides of the rotatable placement table 6, place the V-shaped groove 4 at the bottom of the measuring ruler 2 on the roller surface along the axial direction of the roller, and then adjust the measuring ruler 2 along the circumferential direction of the roller so that both the first level bubble 5 and the second level bubble 7 on the measuring ruler 2 are in the middle position;

[0045] Third, place the reflecting ball 8 in the measuring through-hole 11 on the placement table 6, adjust the reflecting ball 8 so that it is aligned with the measuring instrument (such as a total station, etc.), and finally perform data acquisition.

[0046] It can be seen from this that the device can effectively improve the measurement accuracy and measurement efficiency of the roll system level measurement, reduce the complexity of its calculation, can quickly complete the measurement of different roll systems, improve the measurement efficiency while ensuring the measurement accuracy. At the same time, this device can also be applied to the level measurement of other equipment. In addition, the device has four horizontal card slots 3 with different heights, so the measurement position can be adjusted according to the measurement line of sight during measurement, and the values between these four heights are standard values and can be directly cited during calculation, thus effectively solving the problem of occlusion of on-site equipment during measurement. Moreover, the contact between the V-shaped groove 4 and the roller surface is two-line contact. Therefore, the stability of the device during measurement is much greater than the single-line contact of the level gauge, thus effectively reducing the human error caused by stability during the measurement process. In addition, since the bottom of the measuring ruler 2 is designed with a V-shaped groove 4 with a design angle of 150°, when the diameter of the measured roller is known, the height of the upper surface of the roller can be calculated through the angle and the roller diameter, so that height comparison can be carried out even if the roller diameters are different, which has universality. After the placement table 6 is installed, the measuring through-hole 11 is located outside the measuring ruler 2, and the reflecting ball 8 can be adjusted in the horizontal direction by 180° after being placed; at the same time, the measuring ruler 2 can also be rotated horizontally by 180°, so that a 360° direction adjustment of the reflecting ball 8 can be achieved, which can greatly expand its measurement line of sight. Secondly, this device has universality, can measure roll systems with lower positions, has strong practicability and a wide application range.

[0047] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
