Description

Technical Field

[0001] The present application relates to the technical field of auxiliary detection of smelting equipment, and in particular to a detection system and method for the wear state of a ladle rotary bearing. Background Art

[0002] The ladle slewing bearing is a key component of the ladle turret in the steelmaking process. When the ladle turret rotates, the rollers of the slewing bearing roll in the raceway, bearing the gravity from the ladle and various loads generated during the rotation process, thereby achieving smooth rotation and accurate positioning of the ladle.

[0003] The ladle turret is a key component of the continuous casting machine, ensuring the ladle's accurate and smooth rotation from the molten steel receiving span to the pouring span for pouring operations. The ladle turret bearings are subject to heavy loads, and damage can result in long repair times and significant disruptions. Traditional replacement methods require dismantling components such as the turret's cross arm and then using lifting equipment for replacement, resulting in a complex and time-consuming process.

[0004] Currently, there is no clear detection method for heavy-loaded, low-speed slewing bearings. Comprehensive evaluation mainly relies on oil monitoring, iron spectrum analysis, big data diagnosis, etc. However, in actual application, there are problems such as unclear characteristics, which leads to delayed acquisition of the operational wear status of the ladle slewing bearings. It is not conducive to maintenance and replacement operations in line with the production rhythm, which increases the detection cost and reduces the detection efficiency. Summary of the Invention

[0010] a positioning member, movably provided on the reference member and capable of limiting the movement of the reference member on the base member;

[0011] The detection member has a detection end that can extend between the reference member and the bearing outer ring, so as to detect the distance between the reference member and the bearing outer ring.

[0012] In an optional embodiment, the reference member is threadedly connected to the base member, and a centerline direction of the reference member is arranged perpendicular to a bottom surface of the bearing outer ring.

[0013] In an optional embodiment, the positioning member is threadedly connected to the reference member, and the top surface of the positioning member can be abutted against the bottom surface of the base member.

[0014] In an optional embodiment, the reference member is a screw and the positioning member is a nut.

[0015] In an optional embodiment, a nut threadedly connected to the reference member is fixedly provided at one end of the base member away from the ladle turntable base.

[0016] In an optional embodiment, the detection member is a feeler gauge.

[0017] In an optional embodiment, the base member is provided with a through hole for accommodating the reference member.

[0019] In an optional embodiment, a plurality of the base members are provided and circumferentially distributed on the base of the ladle turntable, and the reference member is arranged on each of the base members.

[0020] Based on the same inventive concept, the present application also provides a method for detecting the wear state of a ladle slewing bearing, the detection method being applied to the detection system according to any one of claims 1 to 9, the detection method comprising:

[0021] Fix the base part on the base of the ladle turret of the ladle slewing bearing system to be tested; move the reference part toward the outer ring of the bearing, and make the distance between one end of the reference part and the outer ring of the bearing within the measuring range of the testing part;

[0022] Move the detection end of the operating detection piece between the reference piece and the bearing outer ring, and obtain the distance between one end of the reference piece and the bearing outer ring as basic data;

[0023] At different times, operate the test piece to obtain the distance between one end of the reference piece and the bearing outer ring as comparison data;

[0024] Combining basic data with comparative data, the wear status of the ladle slewing bearing is obtained.

[0025] Compared with the prior art, the advantages of this application are:

[0026] The detection system in the present application is used for detecting the wear status of a ladle rotary bearing. The detection system includes a base part, a reference part, a positioning part and a detection part. The base part is used to be fixedly connected to the base of the ladle turntable of the ladle rotary bearing system to be detected. The reference part is movably connected to the base part, and the reference part can move toward or away from the outer ring of the bearing of the ladle rotary bearing system to be detected. The positioning part can be movably provided on the reference part and can limit the movement of the reference part on the base part.

This allows maintenance personnel to repair or replace worn areas in a targeted manner, avoiding blind inspections and repairs and improving maintenance efficiency. Furthermore, timely and accurate bearing wear information allows maintenance personnel to rationally schedule maintenance tasks based on production plans and wear conditions, aligning maintenance work with production schedules and reducing production interruptions caused by maintenance. This increases equipment uptime, indirectly reducing production losses and repair costs caused by downtime.

[0030] Furthermore, by monitoring bearing wear, potential faults can be detected in advance, allowing timely repair or replacement measures to be taken, thus avoiding equipment damage and safety accidents caused by sudden bearing failures. This ensures the reliable operation of the ladle slewing bearing, thereby guaranteeing the smooth operation of the entire steelmaking production. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is intended to help understand the present invention, but does not constitute a limitation of the present invention. The specific structural and functional details disclosed herein are merely intended to describe exemplary embodiments of the present invention. However, the present invention can be embodied in many alternative forms, and it should not be understood that the present invention is limited to the embodiments set forth herein.

[0037] like Figure 1 、 Figure 2 As shown, Figure 1 A schematic diagram of the structure of the detection system provided in an embodiment of the present application; Figure 2 Schematic diagram of the installation of the detection system provided in an embodiment of the present application; a detection system for the wear state of a ladle slewing bearing, the detection system comprising a base member 100, a reference member 200, a positioning member 300 and a detection member, wherein:

[0038] like Figure 1 、 Figure 2 As shown, base member 100 is fixedly connected to the base 401 of the ladle turret of the ladle slewing bearing system to be inspected. Base member 100 serves as the mounting foundation for the inspection system. The shape and dimensions of base member 100 are tailored to the specific structure of the ladle turret base to ensure a secure attachment to the base. High-strength steel can be used to ensure sufficient stability and load-bearing capacity in complex industrial environments.

[0039] The surface of the base member 100 can be precision-machined to ensure a smooth, tight connection between the base member 100 and the ladle turret base, thereby improving the installation accuracy and stability of the entire detection system. The base member 100 can also be provided with multiple mounting holes, allowing high-strength bolts to secure the base member 100 to the ladle turret base 401. This connection method is not only secure and reliable, but also easy to install and remove, facilitating maintenance and replacement of the detection system.

[0040] like Figure 1 、 Figure 2 As shown, the reference member 200 is movably connected to the base member 100 and can be moved toward or away from the outer ring 402 of the ladle slewing bearing system to be inspected. The reference member 200 is mounted on the base member 100 via a movably connected connection, which can be achieved using a slide rail, hinge, or other similar mechanical structure. The shape and size of the reference member 200 enable it to flexibly move toward or away from the outer ring 402 of the ladle slewing bearing system to be inspected.

[0041] In actual applications, the movement range and accuracy of the reference member 200 can be precisely calculated and designed according to the size of the ladle slewing bearing and the wear detection requirements to ensure that the detection member can accurately contact the bearing outer ring 402.

[0042] The reference member 200 can be made of a lightweight and high-strength alloy material to ensure good durability and stability during frequent movement. The surface of the reference member 200 is specially treated to reduce friction with the base member 100 and improve its flexibility and reliability.

[0043] like Figure 1 、 Figure 2 As shown, the positioning member 300 can be movably provided on the reference member 200 and can limit the movement of the reference member 200 on the base member 100 .

[0044] The positioning member 300 is movably mounted on the reference member 200. The primary function of the positioning member 300 is to limit the movement of the reference member 200 on the base member 100 to ensure that the reference member 200 maintains a stable position during the testing process. The positioning member 300 can be configured to include a variety of mechanical locking devices, such as claws, screws, or hydraulic cylinders, which can precisely control the position of the reference member 200 as needed. During the testing process, the reference member 200 is first fixed to an initial position on the base member 100. The position of the reference member 200 is then gradually adjusted based on the testing requirements until the reference member 200 approaches or moves away from the bearing outer ring 402 to the target position, at which point the positioning member 300 is used to relatively secure the reference member 200.

[0045] The detection member has a detection end that can extend between the reference member 200 and the bearing outer ring 402 to detect the distance between the reference member 200 and the bearing outer ring 402 .

[0046] The detection end of the detection component extends between the reference component 200 and the bearing outer ring 402. The shape and size of the detection end can be optimized based on the surface characteristics of the bearing outer ring 402 to ensure close contact with the bearing outer ring 402 and accurately measure the gap between them. The detection component can be a laser displacement sensor or a physical ruler. The measurement range and accuracy of the detection component are configured based on the actual wear of the ladle slewing bearing and the detection requirements, meeting the detection needs under different operating conditions.

[0047] like Figure 1 、 Figure 2 As shown, during the inspection process, the base member 100 is first securely mounted on the ladle turret base 401. The reference member 200 is then flexibly connected to the base member 100 and relatively fixed at a preset initial reference position using the positioning member 300. The detection end of the inspection member extends between the reference member 200 and the bearing outer ring 402, and measurement of the distance between them begins. Subsequently, the inspection member is repeatedly used to measure the change in distance under different conditions. The measurement data is analyzed and processed. By analyzing the inspection data, the wear condition of the ladle slewing bearing can be accurately assessed, providing a scientific basis for subsequent maintenance and replacement operations.

[0048] In an optional embodiment, the detection system in the present application is used for detecting the wear status of a ladle rotary bearing. The working principle of the detection system is as follows: the detection system includes a base member 100, a reference member 200, a positioning member 300 and a detection member. The base member 100 is used to be fixedly connected to the base 401 of the ladle turntable of the ladle rotary bearing system to be detected. The reference member 200 is movably connected to the base member 100, and the reference member 200 can move toward or away from the bearing outer ring 402 of the ladle rotary bearing system to be detected. The positioning member 300 can be movably provided on the reference member 200 and can limit the movement of the reference member 200 on the base member 100. The detection member has a detection end that can extend between the reference member 200 and the bearing outer ring 402, so as to detect the distance between the reference member 200 and the bearing outer ring 402.

[0049] The base member 100 is fixed to the ladle turret base 401, and the reference member 200 is movably connected to the base member 100, making installation and operation much simpler. No extensive disassembly of the ladle turret is required; the inspection system can be simply installed on the ladle turret base 401 for inspection, greatly simplifying the operation process and saving time and labor costs.

[0050] Directly measuring the distance between reference member 200 and bearing outer ring 402 using a detection element provides a more intuitive and accurate picture of bearing wear, avoiding the errors and lags associated with indirect monitoring in traditional methods. The detection end of the detection element can extend between reference member 200 and bearing outer ring 402. This monitoring method can promptly or periodically identify changing trends in bearing wear, providing a basis for early warning and preventive maintenance, and avoiding sudden failures caused by excessive wear.

[0051] By measuring the distance between reference part 200 and bearing outer ring 402 using a detection component, the specific location and extent of wear can be quickly determined. This allows maintenance personnel to repair or replace worn areas in a targeted manner, avoiding blind inspections and repairs and improving maintenance efficiency. Furthermore, timely and accurate bearing wear information allows maintenance personnel to rationally schedule maintenance tasks based on production plans and wear conditions, aligning maintenance work with production schedules and reducing production interruptions caused by maintenance. This increases equipment uptime, indirectly reducing production losses and maintenance costs caused by downtime.

[0052] Furthermore, by monitoring bearing wear, potential faults can be detected in advance, allowing timely repair or replacement measures to be taken, thus avoiding equipment damage and safety accidents caused by sudden bearing failures. This ensures the reliable operation of the ladle slewing bearing, thereby guaranteeing the smooth operation of the entire steelmaking production.

[0053] like Figure 1 、 Figure 2 As shown, in an optional embodiment, the reference member 200 is threadedly connected to the base member 100 , and the centerline direction of the reference member 200 is arranged perpendicular to the bottom surface of the bearing outer ring 402 .

[0054] The centerline direction of the reference part 200 is perpendicular to the bottom surface of the bearing outer ring 402. This vertical arrangement allows the reference part 200 to accurately approach or move away from the bearing outer ring 402 along the vertical direction, thereby realizing wear detection at different height positions of the bearing outer ring 402.

[0055] The threaded connection between the reference member 200 and the base member 100 not only ensures a firm connection between the reference member 200 and the base member 100 , but also facilitates quick installation and removal of the reference member 200 , and facilitates maintenance and adjustment of the detection system.

[0056] like Figure 1 、 Figure 2 As shown, in an optional embodiment, the positioning member 300 is threadedly connected to the reference member 200 , and the top surface of the positioning member 300 can be abutted against the bottom surface of the base member 100 .

[0057] In an optional embodiment, the top surface of the positioning member 300 may abut against the bottom surface of the base member 100. By threading the positioning member 300 onto the reference member 200, the positioning member 300 can precisely control the position of the reference member 200 on the base member 100, ensuring that the reference member 200 remains stable during the detection process. The abutment between the top surface of the positioning member 300 and the bottom surface of the base member 100 maintains the ease of adjustment of the positioning member 300 while limiting the further movement of the reference member 200 through the friction between the top surface of the positioning member 300 and the bottom surface of the base member 100, thereby limiting the range of movement of the reference member 200 and improving the accuracy and reliability of the detection.

[0058] like Figure 1 、 Figure 2 As shown, in an alternative embodiment, the reference member 200 is a screw and the positioning member 300 is a nut. The screw and nut combination is a reliable and effective mechanical structure that enables precise position adjustment and fixation. The screw's threads enable the reference member 200 to maintain stable linear motion during movement, while the nut controls the position of the reference member 200 by tightening or loosening it, resulting in low cost and ease of operation.

[0059] like Figure 1 、 Figure 2 As shown, in an optional embodiment, a nut is fixed to one end of the base member 100 away from the ladle turret base, which is threadedly connected to the reference member 200. The nut on the base member 100 simplifies the fixing and positioning requirements of the reference member 200 and ensures the stability of the reference member 200 on the base member 100. The threaded connection further strengthens the connection between the reference member 200 and the base member 100.

[0060] In an optional embodiment, the detection member is a feeler gauge. A feeler gauge is a measuring tool that can accurately measure the distance between two surfaces. In this detection system, the detection end of the feeler gauge can be flexibly inserted into the gap between the reference member 200 and the bearing outer ring 402, directly measuring the distance between them and accurately reflecting the wear condition of the bearing.

[0061] like Figure 1 、 Figure 2 As shown, in an optional embodiment, the base member 100 is provided with a through-hole for accommodating the reference member 200. The arrangement of the through-holes enables the reference member 200 to pass through the base member 100, thereby enabling vertical movement on the base member 100. This simplifies the installation and adjustment process of the reference member 200 and improves the overall compactness and stability of the detection system.

[0062] like Figure 1 、 Figure 2As shown, in an optional embodiment, the base member 100 is welded to the ladle turret base 401. Welding is a high-strength connection method that ensures a secure connection between the base member 100 and the ladle turret base. Through welding, the base member 100 can withstand greater loads while reducing connection instability caused by loose bolts.

[0063] In an optional embodiment, a plurality of the base members 100 are provided and circumferentially distributed on the ladle turntable base 401 , and the reference member 200 is arranged on each of the base members 100 .

[0064] The circumferential distribution of base components 100 enables the detection system to inspect the ladle slewing bearing from multiple directions, thereby obtaining more comprehensive wear data. The arrangement of multiple base components 100 and reference components 200 improves the accuracy and reliability of the detection, better reflecting the overall wear status of the bearing.

[0065] like Figure 3 As shown, Figure 3 This is a flow chart of a detection method provided in an embodiment of the present application. Based on the same inventive concept, the present application also provides a method for detecting the wear state of a ladle slewing bearing. The detection method is applied to a detection system according to any one of claims 1 to 9, and the detection method includes:

[0066] Before installation, the installation surface of the ladle turntable base must be thoroughly cleaned to remove impurities such as oil, dust, and rust, ensuring that the connection surface between the base member 100 and the base is flat and clean, thereby improving the stability and reliability of the installation;

[0067] Based on the specific location and testing requirements of the ladle slewing bearing, the base member 100 is precisely placed at the predetermined position on the base of the ladle turntable. The positioning accuracy of the base member 100 directly affects the accuracy of subsequent testing, so high-precision measuring tools are required for positioning.

[0068] The base member 100 is fixedly connected to the base 401 of the ladle turntable of the ladle rotary bearing system to be tested;

[0069] Move the reference member 200 toward the bearing outer ring 402 so that the distance between one end of the reference member 200 and the bearing outer ring 402 is within the measuring range of the detection member;

[0070] Specifically: The reference member 200 is mounted on the base member 100 by means of threaded connection or other movable connection methods. In the initial state, the reference member 200 should be located in a suitable position so that the reference member 200 can move smoothly toward the bearing outer ring 402. The position of the reference member 200 is adjusted manually or mechanically so that one end of the reference member 200 is close to the bearing outer ring 402.

[0071] When moving the reference member 200, ensure that the distance between one end of the reference member 200 and the bearing outer ring 402 is within the effective measuring range of the tester. The measuring range of the tester is designed based on the maximum wear of the ladle slewing bearing. Therefore, when adjusting the reference member 200, it is necessary to calibrate it with a ruler or other measuring tool to ensure that the tester can accurately measure the distance in subsequent tests.

[0072] Move the detection end of the operating detection member to between the reference member 200 and the bearing outer ring 402, and obtain the distance between one end of the reference member 200 and the bearing outer ring 402 as basic data;

[0073] Specifically, the testing tip of the test piece is precisely inserted into the gap between the reference piece 200 and the bearing outer ring 402. The positioning accuracy of the testing tip directly affects the accuracy of the basic data. Therefore, a high-precision positioning device or manual adjustment of the testing tip is required to ensure good contact with the gap. The basic data must be recorded in detail and accurately, including information such as the test time, test location, and test environment, to facilitate subsequent analysis and comparison.

[0074] At different times, the detection member is operated to obtain the distance between one end of the reference member 200 and the bearing outer ring 402 as comparative data;

[0075] A reasonable inspection cycle is established based on the frequency of use and wear of the ladle slewing bearing. Within each inspection cycle, the above steps are repeated, inserting the inspection end of the inspection member into the gap between the reference member 200 and the bearing outer ring 402 to collect the current spacing data.

[0076] Combining basic data with comparative data, the wear status of the ladle slewing bearing is obtained.

[0077] All collected comparative data is centrally managed and analyzed. This provides data support for subsequent wear status assessments. Comparative data collected at different time points is compared and analyzed with baseline data. By calculating the difference between the comparative data and baseline data, the wear of the ladle slewing bearing at different time points can be determined.

[0078] Based on wear data from multiple time points, a wear versus time curve is plotted to assess the wear trend of the ladle slewing bearing. If the wear increases gradually over time, it indicates normal bearing wear. If the wear increases sharply in a short period of time, it may indicate abnormal bearing wear or potential failure.

[0079] The wear status of the ladle slewing bearing can be determined based on the wear volume and wear trend, combined with the design life and allowable wear volume. If the wear volume exceeds the allowable range, timely maintenance or replacement measures should be implemented to avoid equipment failure and production accidents caused by excessive bearing wear.

[0080] The above detection method enables accurate detection and real-time monitoring of the wear status of the ladle slewing bearing. This not only enables timely identification of bearing wear issues but also provides data support for preventive maintenance, thereby improving equipment reliability and production efficiency while reducing maintenance costs and production risks.
