Description

Technical Field

[0001] The present invention relates to the technical field of vibration measurement, and more particularly to an on-line dynamic amplitude anti-deviation laser monitoring device for a guard guide plate. Background Art

[0002] The guard is a key device in the rolling process, mainly used to guide the rolled piece to accurately and stably enter and exit the roll pass, ensuring the safety of the rolling process and the product quality. When the rolled piece enters and exits the roll, the guide plate prevents the rolled piece from swinging and twisting due to deformation force or thermal expansion through mechanical restriction or friction, thereby avoiding winding around the roll or jamming in the pass, and then effectively restraining the rolled piece and reducing the rate of steel stacking accidents.

[0003] The vibration of the guard guide plate is a common phenomenon in rolling production. Excessive amplitude will lead to unstable rolling, product size deviation and even equipment damage. Therefore, it is necessary to continuously monitor the amplitude of the guide plate. The commonly used monitoring methods include contact type and non-contact type. Among them, the laser Doppler vibrometer has many advantages such as high monitoring accuracy and fast response speed. When the existing guide plate amplitude monitoring device is in use, the amplitude of the guide plate can be measured by a vibration monitor. However, the guide plate is prone to shift during long-term vibration. When the position of the guide plate changes, the amplitude monitoring error will increase. And during the monitoring process, the vibration of the rolling equipment and the guide plate will be transmitted to the vibration monitor, causing the vibration monitor to resonate at a certain frequency, which will not only affect the structural stability of the monitoring device, but also have an adverse effect on the monitoring accuracy.

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 to 9 , the present invention provides a technical solution: A laser monitoring device for online dynamic amplitude anti-deviation of a guide and guard guide plate, comprising a fixing frame 11, an installation groove 13 is provided on the outer surface of the upper end of the fixing frame 11, a movable rod 16 for supporting the guide plate 14 is fixedly connected inside the installation groove 13, and a limit assembly is arranged outside the movable rod 16; The limiting component includes a notch 25 formed on the outer surface of the guiding plate 14. A limiting sleeve 26 is fixedly connected to the outer surface of the movable rod 16. A pressing crack 27 is formed on the outer surface of the limiting sleeve 26. The limiting sleeve 26 penetrates into the notch 25. The guiding plate 14 is in contact with the outer surface of the limiting sleeve 26 through the notch 25. A receiving groove 44 is formed on the outer surface of the movable rod 16. An extrusion plate 45 is fixedly connected inside the receiving groove 44. The extrusion plate 45 is in contact with the inner surface of the limiting sleeve 26.

[0021] The number of the notches 25 and the limiting sleeves 26 are both two groups and are symmetrically distributed on the front and rear sides of the guiding plate 14. The limiting sleeve 26 is made of an elastic material. The extrusion plate 45 is arc-shaped. The number of the pressing cracks 27 is several groups and is distributed in a circular array. The outer surface of the limiting sleeve 26 is conical.

[0022] By adopting the above technical solution, during the operation of the guide guard, the lower surface of the rolled steel is in sliding contact with the tip of the guiding plate 14. The rolled steel is guided by the guiding plate 14 to accurately enter between the rolling rolls, thereby improving the rolling processing precision of the rolled steel. The installation groove 13 on the surface of the fixing frame 11 is used to fixedly support the movable rod 16. The guiding plate 14 is rotationally supported by the support rod 22 so that the guiding plate 14 can swing with the movable rod 16 as a fulcrum. During the reciprocating vibration of the guiding plate 14, it is easy to generate an offset on the surface of the movable rod 16. Therefore, a limiting component is provided. The limiting sleeves 26 on the surface of the movable rod 16 are distributed on both sides of the guiding plate 14. The inclined surface of the limiting sleeve 26 can play a limiting role on the guiding plate 14. When the guiding plate 14 has an accidental offset, the notch 25 on the surface of the guiding plate 14 will be in contact with one of the limiting sleeves 26. At this time, the guiding plate 14 will extrude the limiting sleeve 26 through the notch 25, causing a certain amount of elastic deformation of the limiting sleeve 26. The uniformly distributed pressing cracks 27 on the surface of the limiting sleeve 26 can reduce the pressure generated by the deformation of the limiting sleeve 26 to a certain extent. When the limiting sleeve 26 is extruded inward, the limiting sleeve 26 will extrude the extrusion plate 45. The movable rod 16 fixedly supports the extrusion plate 45 through the receiving groove 44. At this time, the extrusion plate 45 will push the limiting sleeve 26 to expand outward in the reverse direction under its own elastic force. The limiting sleeve 26 pushes the guiding plate 14 in the reverse direction through the notch 25, so that the guiding plate 14 gradually moves back to its original position along the surface of the movable rod 16, thereby realizing the automatic correction of the position of the guiding plate 14. By setting the limiting component, when the guiding plate 14 has a position offset, the limiting sleeve 26 can play a role in correcting the deviation of the guiding plate 14, so that the position of the guiding plate 14 is always in an appropriate position, thereby reducing the influence of the position offset of the guiding plate 14 on the measurement accuracy of the vibration amplitude of the guiding plate 14 to a certain extent, and further reducing the monitoring error to improve the monitoring accuracy.

[0023] Specifically, such as Figure 3 、Figure 4 and Figure 7 As shown, a traction assembly is provided on the lower side of the guide plate 14. The traction assembly includes a piston cylinder 17 fixedly connected to the upper end of the inner surface of the installation groove 13. A piston plate 19 is slidably connected to the inner surface of the piston cylinder 17. A push rod 20 is fixedly connected to the upper end of the piston plate 19. The push rod 20 penetrates to the upper side of the piston cylinder 17 and is slidably connected to the piston cylinder 17.

[0024] A guide groove 23 is formed on the outer surface of the lower end of the guide plate 14. A support rod 22 is slidably connected to the inner side of the guide groove 23. The upper end of the push rod 20 is fixedly connected to the support rod 22. A casting cavity 12 is formed through the outer surface of the front end of the fixed frame 11.

[0025] By adopting the above technical solution, during the reciprocating vibration of the guide plate 14, in order to keep the movement amplitude of the guide plate 14 within an appropriate range, a traction assembly is provided. The fixed frame 11 fixedly supports the piston cylinder 17 through the installation groove 13. The piston cylinder 17 supports the push rod 20 through the piston plate 19. An appropriate amount of coolant is filled inside the piston cylinder 17. The coolant will apply an upward thrust to the piston plate 19. The guide groove 23 formed on the surface of the guide plate 14 is used to slidably support the support rod 22. When the guide plate 14 vibrates with the movable rod 16 as a fulcrum, the position of the support rod 22 inside the guide groove 23 will change. The push rod 20 pushes the guide plate 14 upward through the support rod 22, so as to prevent the guide plate 14 from turning downward too much and enable the guide plate 14 to have enough thrust to turn upward and reset. By setting the traction assembly, the guide plate 14 can vibrate more smoothly under the action of the thrust, thereby improving the stability of the guide plate 14 during the vibration to a certain extent.

[0026] Specifically, as Figure 6 and Figure 9 shown, a baffle 15 is fixedly connected to the inner side of the installation groove 13. A monitoring assembly is provided on the outer surface of the baffle 15. The monitoring assembly includes a sleeve one 31 fixedly connected to the outer surface of the baffle 15. A guide seat 34 is fixedly connected to the inner surface of the sleeve one 31. A sleeve two 36 is in movable contact with the outer surface of the guide seat 34. A slide plate 39 is slidably connected to the inner surface of the sleeve two 36.

[0027] A buffer pad 40 is fixedly connected to the outer surface of the slide plate 39. A base 41 is fixedly connected to the outer surface of the buffer pad 40. A vibration monitor 42 is fixedly connected to the side of the outer surface of the base 41 away from the slide plate 39. The vibration monitor 42 penetrates to the outside of the sleeve two 36. A reflector 28 is fixedly connected to the outer surface of the lower end of the guide plate 14. A photosensitive plate 30 is fixedly connected to the upper end of the inner surface of the installation groove 13. The vibration monitor 42, the reflector 28 and the photosensitive plate 30 are in the same vertical plane.

[0028] By adopting the above technical solution, when measuring the vibration amplitude and vibration frequency of the guide plate 14, the fixing frame 11 fixedly supports the first sleeve 31 through the baffle 15, the first sleeve 31 movably supports the second sleeve 36 through the guide seat 34, the slide plate 39 inside the second sleeve 36 fixedly supports the base 41 through the buffer pad 40, and the buffer pad 40 between the slide plate 39 and the base 41 can absorb the vibration received by the second sleeve 36, so as to reduce the transmission of the vibration shock wave to the base 41. The vibration monitor 42 on the surface of the base 41 emits laser light to irradiate the surface of the reflector 28 on the lower side of the guide plate 14, and then the laser light is reflected by the reflector 28 to the surface of the photosensitive plate 30 and forms a light spot on the surface of the photosensitive plate 30. The vibration amplitude of the guide plate 14 is measured and calculated according to the change of the light spot position on the surface of the photosensitive plate 30. The symmetrically distributed vibration monitors 42, reflectors 28 and photosensitive plates 30 can carry out contrast monitoring, which helps to reduce the monitoring error. By setting the monitoring component and adopting the laser monitoring method, not only can the monitoring accuracy of the vibration amplitude of the guide plate 14 be effectively improved, but also the guide plate 14 will be worn during long-term use, and the monitoring component can reduce the influence of the wear of the guide plate 14 on the monitoring accuracy of the vibration amplitude, so as to further improve the monitoring accuracy.

[0029] Specifically, as Figure 6 shown, a buffer component is arranged between the first sleeve 31 and the second sleeve 36. The buffer component includes a vibration isolation plate 32 fixedly connected to the inner surface of the first sleeve 31. The upper outer surface of the vibration isolation plate 32 is fixedly connected with an extrusion sleeve 33. The outer surface of the extrusion sleeve 33 is arc-shaped. The upper outer surface of the extrusion sleeve 33 is fixedly connected with a support sleeve 37.

[0030] One end of the support sleeve 37 away from the vibration isolation plate 32 is fixedly connected with a folding airbag 38. The outer surface of the folding airbag 38 is fixedly connected with the slide plate 39. The folding airbag 38 and the extrusion sleeve 33 are both made of elastic materials. Through holes 43 are formed through the outer surface of the vibration isolation plate 32. The folding airbag 38 is communicated with the inside of the support sleeve 37.

[0031] By adopting the above technical solution, when measuring the vibration amplitude of the guide plate 14 with the vibration monitor 42, in order to reduce the vibration transmission of the guide plate 14 to the vibration monitor 42, a buffer assembly is provided. When the vibration of the guide plate 14 is transmitted to the fixed frame 11 through the movable rod 16, it will cause the fixed frame 11 to generate slight vibrations with a certain frequency. At this time, the shock wave of the vibration will be transmitted to the first sleeve 31. The first sleeve 31 and the second sleeve 36 are in movable contact through the guide seat 34. The outer surface of the guide seat 34 is conical, which can keep the centers of the second sleeve 36 and the first sleeve 31 consistent. When the first sleeve 31 and the guide seat 34 vibrate, the frictional force between the guide seat 34 and the second sleeve 36 can absorb the vibration impact force to a certain extent, so as to reduce the vibration transmission to the second sleeve 36 and the vibration monitor 42, and further reduce the influence of the vibration of the monitor 42 on the measurement accuracy of the vibration amplitude of the guide plate 14. When the vibration transmitted to the first sleeve 31 reaches the vibration isolation plate 32, the vibration will be transmitted to the folding airbag 38 through the extrusion sleeve 33 and the support sleeve 37. Certain amplitude of elastic deformation will occur inside the folding airbag 38 and the extrusion sleeve 33. Through the deformation of the folding airbag 38 and the extrusion sleeve 33, the shock wave of the vibration can be further absorbed, so as to effectively reduce the vibration transmission to the vibration monitor 42, and effectively reduce the influence of the self-vibration of the vibration monitor 42 on the monitoring accuracy.

[0032] Specifically, as Figure 4 shown in Figure 7 Figure, a lubrication assembly is provided outside the piston cylinder 17. The lubrication assembly includes a fixed sleeve 18 fixedly connected to the outer surface of the piston cylinder 17. An overflow groove 29 is provided between the piston cylinder 17 and the fixed sleeve 18. A first conduit 21 is embedded inside the inner side of the ejector rod 20. The lower end of the first conduit 21 penetrates to the lower side of the piston plate 19. A second conduit 24 is embedded inside the inner side of the support rod 22. The upper end of the first conduit 21 is communicated with the inside of the second conduit 24. Both the front and rear ends of the second conduit 24 penetrate to the outside of the support rod 22.

[0033] The number of the vibration monitors 42, the reflector plates 28 and the photosensitive plates 30 is two groups each, and they are symmetrically distributed on both sides of the fixed sleeve 18. The outer surface of the guide seat 34 is inclined. A pressure valve is provided inside the first conduit 21.

[0034] By adopting the above technical solution, when the support rod 22 slides inside the guide groove 23, in order to reduce the wear of the support rod 22 and the resistance during the movement of the support rod 22, a lubrication assembly is provided. During operation, a sufficient amount of lubricating fluid is filled into the fixed sleeve 18. The lubricating fluid inside the fixed sleeve 18 is communicated with the inside of the piston cylinder 17 through the overflow groove 29. When the guide plate 14 swings downward, the guide plate 14 pushes the piston plate 19 downward through the ejector rod 20. When the piston plate 19 moves downward inside the piston cylinder 17, the lubricating fluid will be compressed. At this time, the lubricating fluid inside the piston cylinder 17 enters the inside of the conduit 1 21 through the pressure valve, and then the lubricating fluid flows into the conduit 2 24 through the conduit 1 21. Subsequently, the lubricating fluid overflows from both ends of the support rod 22. The lubricating fluid can lubricate between the support rod 22 and the guide groove 23, so as to effectively reduce the friction between the support rod 22 and the guide groove 23. At the same time, it also helps to reduce the wear of the support rod 22 during long-term movement, improving the operation stability of the monitoring device and effectively increasing the service life of the monitoring device.

[0035] Working principle: When the laser monitoring device is working, the mounting groove 13 on the surface of the fixed frame 11 is used to fixedly support the movable rod 16. The guide plate 14 is rotationally supported by the support rod 22 so that the guide plate 14 can swing with the movable rod 16 as a fulcrum. The vibration monitor 42 emits laser light that irradiates the surface of the reflector 28 on the lower side of the guide plate 14. Then the laser light is reflected by the reflector 28 to the surface of the photosensitive plate 30 and forms a light spot on the surface of the photosensitive plate 30. The vibration amplitude of the guide plate 14 is measured and calculated according to the change in the position of the light spot on the surface of the photosensitive plate 30. The friction between the guide seat 34 and the sleeve 2 36 can absorb the vibration impact force to a certain extent, so as to reduce the vibration transmitted to the sleeve 2 36 and the vibration monitor 42, and further reduce the influence of the vibration of the monitor 42 on the measurement accuracy of the amplitude of the guide plate 14. The deformation of the folding airbag 38 and the extrusion sleeve 33 can further absorb the shock wave of the vibration. The ejector rod 20 pushes the guide plate 14 upward through the support rod 22, so as to prevent the guide plate 14 from turning downward too much and make the guide plate 14 have enough thrust to turn upward and reset. The lubricating fluid flows into the conduit 2 24 through the conduit 1 21. Subsequently, the lubricating fluid overflows from both ends of the support rod 22. The lubricating fluid can lubricate between the support rod 22 and the guide groove 23, so as to effectively reduce the friction between the support rod 22 and the guide groove 23. At the same time, it also helps to reduce the wear of the support rod 22 during long-term movement.
