Description

Technical Field

[0001] This utility model belongs to the field of thrust wheel technology and relates to an eighteen-roller thrust wheel condition detection device. Background Technology

[0002] In the operation of an 18-roll cold rolling mill, the thrust roller plays a certain role, mainly used to bear and limit the axial force of the rolls, ensuring that the rolls can maintain the correct position and axial stability during the rolling process, preventing the work rolls from moving axially, and ensuring production accuracy.

[0003] Thrust wear in rolling mills can lead to various losses, mainly including the following:

[0004] 1. Equipment failure and downtime losses: The 18-roll cold rolling mill operates at high speeds, and the performance of the worn thrust bearing deteriorates, potentially causing rapid temperature increases in components, mill vibration, or even bearing seizure, leading to the burnout of the thrust bearing and rolls. This necessitates downtime for repairs, disrupting production continuity. Frequent replacement of worn parts such as thrust rollers, bearings, and gaskets increases spare parts costs and the workload of maintenance personnel.

[0005] 2. Decreased production precision and efficiency: Thrust erosion, jamming, and wear can lead to axial positioning deviations in the rolls. Roll system misalignment affects the uniformity and flatness of the steel sheet, and issues such as strip misalignment increase the scrap rate. While impacting product quality and customer satisfaction, the increased scrap rate also leads to raw material waste and higher production costs.

[0006] Therefore, it is necessary to provide a device for real-time detection of the thrust wheel condition in the prevention of thrust wear and erosion in rolling mills. Utility Model Content

[0046] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0047] In the description of this utility model, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," and "bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and do not require that this utility model be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model. The terms "connected," "linked," and "set up" used in this utility model should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a direct connection or an indirect connection through intermediate components; a wired connection, a radio connection, or a wireless communication signal connection. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0048] Please see Figure 1-7 The present invention provides the following technical solution: an eighteen-roller thrust wheel state detection device, the detection device comprising: driven wheel 1, vibration probe 5 and Hall effect assembly.

[0049] Specifically, the driven wheel 1 and the thrust wheel 91 are in a rolling connection, which can also be understood as the driven wheel 1 being attached to the thrust wheel 91. The thrust wheel 91 is one of the main components of the thrust structure 9 used to axially limit the work roll 10 in the 18-roll mill. In this design, the thrust wheel 91 acts as the driving wheel, rotating the driven wheel 1. The vibration probe 5 is connected to the thrust structure and is used to detect the vibration amplitude of the entire thrust structure. The vibration probe 5 can be a vibration probe from the prior art. The Hall effect assembly includes a Hall effect probe 2 and a magnet 3. The magnet 3 is located on the circumferential sidewall of the driven wheel 1. For example, a mounting hole can be made on the circumferential sidewall of the driven wheel 1, and the magnet 3 can be embedded in the mounting hole, i.e., the magnet 3 can be installed inside the driven wheel 1; or, the magnet 3 can be glued to the circumferential sidewall of the driven wheel 1. Hall probe 2 is spaced apart from driven wheel 1, meaning Hall probe 2 is placed at a certain distance from magnet 3 (usually between a few millimeters and a few centimeters, depending on the brand of Hall probe 2 used) to detect the rotation of thrust wheel 91. Hall probe 2 can be any existing Hall probe 2. Without altering or damaging thrust wheel 91, this measuring device measures whether thrust wheel 91 rotates and simultaneously judges the vibration amplitude, achieving real-time monitoring of the state of thrust wheel 91. This solves the various efficiency losses caused by thrust wear in existing technologies, prevents thrust wear and ablation, and provides immediate feedback to mill operators in case of abnormalities, avoiding personal injury and property damage caused by equipment failures. It ensures timely equipment maintenance, reduces product defect rate (also known as scrap rate), and improves product quality. This measuring device plays a crucial role in achieving efficient production and improving automation in 18-roll mill production lines.

[0050] See Figure 6 and Figure 7 The thrust structure 9 is located at both ends of the work roll 10. The thrust structure 9 includes a thrust wheel 91 and a mounting base 92. The circumferential sidewall of the thrust wheel 91 rolls in contact with the circumferential sidewall of the work roll 10. Two thrust wheels 91 are connected in series within the mounting base 92, meaning the two thrust wheels 91 are fixed within the mounting base 92 via the same rotating shaft. The mounting base 92 supports the thrust wheels 91. Simultaneously, the mounting base 92 is detachably connected to the bracket 4 used to mount the driven wheel 1, Hall effect sensor 2, and vibration sensor 5, for example, by means of screws or other structural connections. Thus, the thrust structure 9, bracket 4, and vibration sensor 5 are connected together, facilitating vibration detection of the entire thrust structure 9 by the vibration sensor 5. It should be noted that a frame for mounting the work roll 10 has four thrust wheels 91, distributed in pairs on the operating side and drive side of the rolling mill.

[0051] See Figure 5As shown, this detection device also includes a computer 8. The computer 8 is communicatively connected to the vibration probe 5 and the Hall probe 2, respectively. Thus, each vibration probe 5 and each Hall probe 2 transmits the measured data to the computer 8 in the control room. The computer 8 performs status judgment, and if an abnormality is detected, an alarm is triggered. For example, the computer 8 alerts the thrust wheel 91 to an abnormality via a display screen or loudspeaker, achieving real-time monitoring. This detection device features fast response speed and high accuracy. It should be noted that in actual use, if... Figure 6 As shown, bracket 4 can be installed below thrust structure 9.

[0052] The following describes several scenarios of pushback exceptions and how to identify them:

[0053] 1) Vibration probe 5 detects a vibration value that is significantly and continuously higher than the normal value, which is considered abnormal and can trigger an alarm.

[0054] 2) Hall probe 2 detects that none of the four thrust rollers 91 are rotating [Case 1: The forces of the roller system are in balance and the vibration detection is normal, so the thrust rollers are in a non-contact state (very rare), that is, the thrust rollers 91 and the working rollers 10 are not in contact; Case 2: The thrust rollers 91 are not rotating and are accompanied by severe vibration, indicating that the thrust rollers 91 have been burned], then an alarm is triggered.

[0055] 3) If Hall probe 2 detects that the single-sided thrust wheel 91 is rotating and the vibration is normal, then the operation is considered normal; if the vibration is abnormal, an alarm will be triggered.

[0056] 4) If Hall probe 2 detects that the double-sided thrust wheels 91 are rotating and the vibration is normal, then the operation is considered normal; if the vibration is abnormal, an alarm will be triggered.

[0057] As a preferred embodiment of the above embodiments, in this embodiment, the detection device further includes a bracket 4. The bracket 4 is used to mount the driven wheel 1, the Hall probe 2, and the vibration probe 5, and serves as a support. The specific structure of the bracket 4 is not limited in this embodiment, as long as it enables the driven wheel 1, the Hall probe 2, and the vibration probe 5 to function normally.

[0058] As a specific embodiment of the aforementioned bracket 4, in this embodiment, the bracket 4 includes: a base 41, uprights 42, and connecting members 43. The base 41 is detachably connected to the thrust structure 9 (referring to the mounting base 92), such as by screws or other structural connections, facilitating installation and disassembly. Multiple spaced uprights 42 are rotatably connected to the base 41 via connecting members 43 (such as screws). The screws are horizontally positioned, facilitating installation and disassembly, while the uprights 42 possess rotational freedom, allowing them to rotate around the screws (i.e., swing up and down). Figure 2In the diagram shown, the lower part of column 42 is rotatably connected to base 41. Without considering spring 6, column 42 can rotate left and right along the screw. Driven wheel 1 is located between two adjacent columns 42, and is connected to column 42 via shaft 11. A bearing is also provided between driven wheel 1 and shaft 11, facilitating the rotation of driven wheel 1 following thrust wheel 91. Figure 2 In the image shown, the driven wheel 1 is mounted on the upper part of the column 42. The Hall sensor 2 and the vibration sensor 5 are both mounted on the base 41. Figure 4 In the image shown, the Hall sensor 2 is vertically positioned within the protrusion on the base 41. Preferably, see [reference needed]. Figure 2 As shown, multiple mounting slots for supporting columns 42 are spaced apart along the length of the base 41. After the columns 42 are placed in the mounting slots, the connectors 43 are inserted through the base 41 along the length of the base 41, thereby connecting the base 41 and the multiple columns 42 together.

[0059] It should be noted that two driven wheels 1, two Hall probes 2 and two vibration probes 5 can be installed on one bracket 4, so as to better fit the thrust structure 9 (because one thrust structure 9 contains two thrust wheels 91).

[0060] See Figure 2 As shown, the detection device also includes a spring 6. The spring 6 is positioned away from the thrust wheel 91 relative to the column 42, while the middle part of the column 42 is connected to the base 41 via the spring 6. The spring 6 is used to keep the driven wheel 1 pressed tightly against the thrust wheel 91. See also... Figure 1 As shown, the bracket 4 also includes a push rod 7. The push rod 7 is fixedly connected between two adjacent columns 42. A spring 6 is arranged perpendicular to the push rod 7, and the spring 6 has a first connecting end and a second connecting end. The first connecting end of the spring 6 is connected to the base 41, and the second connecting end of the spring 6 is connected to the push rod 7. Preferably, the spring 6 is connected to the middle of the push rod 7. Figure 2 In the image shown, the base 41 (or the side of the base 41 in the width direction) where the spring is located is bent upwards, causing the spring 6 to be tilted relative to the Hall probe 2. Under the elastic force of the spring 6, the spring 6, through the push rod 7, pushes the column 42 to rotate in the direction of the thrust wheel 91, ensuring that the driven wheel 1 is always in close contact with the thrust wheel 91. Because this detection device is in close contact with the thrust wheel 91, when the thrust wheel 91 vibrates, the vibration probe 5 converts the sensed vibration into an electrical signal. Then, through signal processing and analysis, the vibration amplitude is measured to determine whether the vibration of the thrust wheel 91 is normal. See also... Figure 4 As shown, a first limiting post is provided on the base 41, located inside the first connecting end of the spring 6, and a second limiting post is provided on the push rod 7, located inside the second connecting end of the spring 6. Both limiting posts are used to restrict the movement direction of the spring 6, so that the spring 6 moves along the direction of the limiting post, while preventing the spring 6 from twisting during operation.

[0061] See Figure 3 As shown, two driven wheels 1 are mounted on the base 41, meaning the number of driven wheels 1 matches the number of thrust wheels 91. The number of vibration probes 5 and Hall effect sensors also matches the number of driven wheels 1, allowing for real-time monitoring of the state of each thrust wheel 91 (whether it rotates and the amplitude of vibration). Figure 7 In the middle, there are four thrust wheels 91 corresponding to one bracket, and the total number of driven wheel 1, vibration probe 5 and Hall probe 2 are four.

[0062] The main functions of this detection device in preventing thrust wear and erosion in rolling mills are as follows:

[0063] 1. Reduce equipment maintenance costs: Erosion of the thrust roller 91 will accelerate its wear and is likely to affect the rolls, causing serious damage. Reducing erosion can extend the service life of the thrust roller 91, reduce the replacement frequency, thereby reducing equipment maintenance time and labor costs, and also reducing the procurement cost of spare parts.

[0064] 2. Improve production efficiency: Erosion of the thrust roller 91 can cause equipment failure and lead to production line shutdown. Reducing erosion can lower the equipment failure rate, reduce downtime, enable the rolling mill to operate continuously and stably, improve production efficiency, and increase product output.

[0065] 3. Improve product quality: 91mm ablation of the thrust roller can affect the rolling accuracy and stability of the rolling mill, leading to problems such as dimensional deviations and decreased surface quality. Reducing ablation helps ensure the normal operation of the rolling mill, improves rolling accuracy, thereby enhancing product quality and reducing scrap rates.

[0066] 4. Ensuring Production Safety: Severely ablated thrust rollers (91) may break or experience other unexpected situations, leading to safety accidents. Reducing ablation lowers safety risks, creates a safe working environment for production personnel, and avoids personal injury and property damage caused by equipment malfunctions.

[0067] As is known from common technical knowledge, this utility model can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
