[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] The purpose of this invention is to provide a measurement system, measurement method, and reference device for fixed tension reduction equipment to solve the problem of quickly measuring or adjusting the center line during routine maintenance or malfunctions of fixed tension reduction machines. It can quickly and accurately measure the deviation value of the positioning block of the fixed tension reduction machine, and meet the measurement needs of fixed tension reduction machines in different maintenance scenarios.

[0038] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Example 1

[0040] This embodiment provides a measurement system for a type of tension reduction device, such as... Figures 1-8 As shown, it includes: two reference devices 1, which are fixedly installed on the outside of the front lower slide plate 2.1.2 and the rear lower slide plate 2.1.1 of the tension reduction mill 2, respectively; the reference device 1 includes a column 1.2 connected to the lower slide plate 2.1 and a reference block 1.3 set at the top of the column 1.2. The reference block 1.3 is provided with a horizontal centerline positioning surface 1.6 as a reference for adjusting the rolling centerline and an elevation positioning surface 1.7 as a reference for adjusting the elevation. The horizontal centerline positioning surfaces 1.6 of the two reference devices 1 are used to jointly define a reference straight line. By measuring the relative position of component 2 of the tension reduction machine to the reference line and combining it with the installation data of reference device 1, the wear amount or deviation value of the component is calculated. By installing reference device 1 on the outside of the front lower slide plate 2.1.2 and the rear lower slide plate 2.1.1 of the tension reduction machine 2, and defining the reference line using the horizontal center line positioning surface 1.6 on the reference block 1.3, a reliable reference is provided for subsequent measurement of the wear amount or deviation value of component 2 of the tension reduction machine. This makes the measurement process more standardized and precise, and can greatly improve the accuracy and consistency of the measurement results.

[0041] In a preferred embodiment, the reference device 1 further includes an L-shaped step 1.1. The column 1.2 is connected to the lower slide plate 2.1 via the L-shaped step 1.1, and the L-shaped steps 1.1 of the two reference devices 1 are oriented in opposite directions. The L-shaped step avoids the column 1.2 being too close to the lower slide plate 2.2, thus preventing interference with the normal installation and adjustment of the lower slide plate 2.2. This ensures the installation space and subsequent adjustability of the lower slide plate 2.2, enhances the rationality and stability of the equipment structure, and further improves the reliability of the entire equipment measurement system.

[0042] In a preferred embodiment, the reference device 1 further includes a positioning groove 1.8, and the reference block 1.3 is positioned in the positioning groove 1.8 by fasteners. The bottom surface of the positioning groove 1.8 is provided with bolt holes 1.8.1 for mounting bolts 1.4 and pin holes 1.8.2 for mounting positioning pins 1.5. The positioning groove 1.8, in conjunction with the bolt holes 1.8.1 and pin holes 1.8.2, precisely fixes the position of the reference block 1.3, ensuring the stability and accuracy of the reference block 1.3 in the reference device 1. This makes the horizontal centerline positioning surface 1.6 and the elevation positioning surface 1.7 provided by the reference block 1.3 more reliable as measurement references, and helps to improve the accuracy when measuring the parameters of the tension reduction machine 2 components.

[0043] In a preferred embodiment of this invention, the two reference devices 1 satisfy the following conditions after installation:

[0044] The distance difference between the two horizontal centerline positioning surfaces 1.6 and the rolling centerline is within ±0.1mm;

[0045] The height difference between the two elevation positioning surfaces 1.7 and the rolling center line is within ±0.1mm;

[0046] The horizontal distance between the line connecting the two horizontal centerline positioning surfaces 1.6 and the positioning block liner 2.4 is less than 10mm.

[0047] By strictly limiting the distance difference between the horizontal centerline positioning surface 1.6 and the rolling centerline of the two reference devices 1, the height difference between the elevation positioning surface 1.7 and the rolling centerline, and the horizontal distance between the line connecting the horizontal centerline positioning surface 1.6 and the positioning block liner 2.4, the errors generated when using traditional tools to measure and adjust the rolling centerline of the positioning block 2.3 or the positioning block liner 2.4 can be greatly reduced, further ensuring the accuracy of the measurement results and providing more accurate data for equipment maintenance and adjustment.

[0048] Example 2

[0049] This embodiment also provides a measurement method using a fixed-tension reduction equipment measurement system as described in any of the embodiments in Example 1, including the following steps:

[0050] S1: At the two horizontal centerline positioning surfaces 1.6 and / or elevation positioning surfaces 1.7, a steel wire is stretched or a long strip-shaped adjustment tool with a straightness range of ±0.1mm is placed to establish a measurement benchmark. By stretching a steel wire or placing a long strip-shaped adjustment tool at a specific position to establish a measurement benchmark, an intuitive and stable reference is provided for subsequent measurement of the distance or height difference between the two components of the tension reduction machine. This makes the measurement process more intuitive and convenient, and can effectively improve the accuracy and operability of the measurement.

[0051] S2: Measure the distance or height difference D between the component to be measured and the measurement reference of the tension reduction machine 2. This clarifies the object of the measurement operation, enables the acquisition of specific data between the component to be measured and the measurement reference, provides a data basis for subsequent calculation of the actual wear or deviation value of the component to be measured, and ensures the integrity and feasibility of the entire measurement method.

[0052] S3: Calculate the actual wear or deviation value ΔD of the component to be tested according to the formula ΔD=D-ΔX; where ΔX is the known difference between the installation reference position and the theoretical position of the reference device 1 (1). The calculation by this formula can eliminate the possible error influence during the installation of the reference device 1, thereby accurately calculating the actual wear or deviation value of the component to be tested, improving the accuracy of the condition assessment of the tension reduction machine 2, and helping to formulate more precise equipment maintenance and adjustment strategies.

[0053] In a preferred embodiment, the component to be measured includes a positioning block 2.3, a positioning block liner 2.4, and a lower slide plate 2.1 or a lower slide plate liner 2.2. This clarifies the range of measurable components, enabling the measurement method to cover the measurement needs of multiple key components in the tension reduction machine 2. This helps to comprehensively assess the wear and deviation of each component of the tension reduction machine 2, providing comprehensive information for the overall maintenance and repair of the equipment.

[0054] In a preferred embodiment, step S2 uses a steel ruler or an inside micrometer for measurement. Steel rulers and inside micrometers are commonly used and highly accurate measuring tools that can meet the required measurement accuracy. At the same time, they are relatively easy to operate, which is conducive to accurately obtaining measurement data in actual operation and improving measurement efficiency and reliability.

[0055] Example 3

[0056] This embodiment also provides a reference device 1 for the measurement system of Embodiment 1, comprising:

[0057] A base for connecting to the equipment base;

[0058] The upright column 1.2 is installed on the base;

[0059] The reference block 1.3 is set at the top of the column 1.2. The reference block 1.3 has a horizontal center line positioning surface 1.6 and an elevation positioning surface 1.7 precisely machined on it.

[0060] The overall structural composition of the reference device 1 was clarified. This structural design enables the reference device 1 to be stably connected to the equipment foundation and to provide a clear and stable measurement reference for the tension reduction machine 2 through the support of the column 1.2, which effectively ensures the smooth progress of the measurement work and the accuracy of the measurement results.

[0061] In a preferred embodiment, the base is an L-shaped step 1.1. Using an L-shaped step as the base inherits the advantages of the L-shaped step in the entire measurement system, avoids interference with related components (such as the lower slide plate 2.2) during installation, and facilitates the connection and cooperation between the reference device 1 and the lower slide plate 2.1, thereby improving the rationality of the overall structure of the equipment and the installation stability of the reference device 1.

[0062] In a preferred embodiment, a positioning groove 1.8 is also included. The reference block 1.3 is fixed in the positioning groove 1.8 by bolts 1.4 and positioning pins 1.5. The cooperation of the positioning groove 1.8, bolts 1.4 and pins further stabilizes and refines the position of the reference block 1.3 in the reference device 1, ensuring the stability and accuracy of the horizontal centerline plane and elevation plane provided by the reference block 1.3 during the measurement process, improving the reliability of the reference device 1 as a measurement reference, and thus improving the measurement accuracy of the entire measurement system.

[0063] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
