[0002] In the rolling production process of the steel and metallurgical industry, the high-speed guide and guide wheel plays an important role in guiding and supporting the rolled piece, and its working state directly affects the quality and production efficiency of the rolled piece. The guide wheel will produce dynamic amplitude during high-speed rotation. If the amplitude is too large, it will cause the rolled piece to deviate, vibration to intensify, and even cause equipment damage and production accidents. Therefore, it is crucial to accurately detect the dynamic amplitude of the high-speed guide and guide wheel.

[0019] 1、The present application uses the linkage of various mechanical parts to achieve multi-dimensional technical breakthroughs, effectively solving the pain points of existing detection technology. The linkage of the laser detection module, mounting base, sleeve assembly and other structures realizes stable fixation of the device through the mounting hole.

[0034] In use, first, the four mounting holes 101 at the four corners inside the mounting base 1 are used to fix the entire device on the corresponding station of the steel rolling production line through fixing members such as bolts, to ensure that the device does not displace or shake when the steel rolling piece 7014 passes at high speed, then the threaded joint 1013 is screwed into the internal thread on the inner wall of the sleeve assembly 1011, precise positioning of the end cover assembly 1015 is achieved through thread cooperation, and then the laser detection module 1016 fixed on the top surface of the end cover assembly 1015 is in the preset detection position, the wiring assembly 1014 at the bottom end of the threaded joint 1013 is led out through the threading hole 1012 arranged in the annular array on the outer peripheral surface of the sleeve assembly 1011, and the circuit connection between the laser detection module 1016 and the external control system is completed, including the power supply circuit and the data transmission circuit;

[0039] In this embodiment, in use, when the surface of the guide wheel assembly 7013 is attached with scale, iron filings and other impurities before the start of laser detection or during detection, the cleaning mechanism is started. First, the servo push rod 2011 in the guide groove 201 longitudinally opened on the left and right sides of the guide support 2 receives a control signal, the output shaft of the servo push rod 2011 is telescopic, drives the moving assembly 2012 fixedly connected with the top end to move longitudinally along the guide groove 201, the slider assembly 2013 of the two protruding structures fixedly connected with the outside of the moving assembly 2012 is embedded in the inner wall groove of the guide groove 201, ensuring that the moving assembly 2012 does not deviate or shake during movement, and then driving the connecting arm 3 fixedly connected with the side away from the guide support 2 of the moving assembly 2012 to adjust the longitudinal position synchronously, so that the connecting arm 3 is aligned with the axial range of the guide wheel assembly 7013;

[0040] The guide push rod 301 in the transverse slot opened in the inside of the connecting arm 3 is started, and the output end of the guide push rod 301 drives the displacement assembly 3011 to move along the transverse slot, and the guide sliding block 3012 fixedly connected with the outside of the displacement assembly 3011 is embedded in the side wall sliding groove of the transverse slot, ensuring the stability and accuracy of the transverse movement of the displacement assembly 3011, and the accurate extension and contraction of the guide push rod 301 adjusts the transverse position of the displacement assembly 3011, so that the rotating shaft mechanism 4 rotatably connected with the inside of the displacement assembly 3011 and the scraper assembly 4014 fixedly connected with the outside of the rotating shaft mechanism 4 are close to the outer circumferential surface of the guide wheel assembly 7013, and a suitable cleaning gap is maintained;

[0041] The servo motor 4012 fixedly connected to the top end of the side plate assembly 4011 away from the connecting arm 3 starts to work. The bottom output shaft of the servo motor 4012 is stably supported on the side plate assembly 4011 through a bearing seat. The output shaft drives the bevel gear B4013 mounted thereon to rotate. Since the bevel gear B4013 is in mesh with the bevel gear A401 fixedly connected to the front end of the rotating shaft mechanism 4, the rotation of the bevel gear B4013 drives the bevel gear A401 and the rotating shaft mechanism 4 to rotate synchronously, so that the scraper assembly 4014 fixed to the outer side of the rotating shaft mechanism 4 rotates around the rotating shaft mechanism 4. The edge of the scraper assembly 4014 is in contact with the surface of the guide wheel assembly 7013, and the impurities on the surface are scraped off in the rotating process.

[0042] During the cleaning process, the servo push rod 2011 and the guide push rod 301 can adjust the position and cleaning strength of the scraper assembly 4014 in real time according to the rotation speed and amplitude change of the guide wheel assembly 7013, so as to efficiently remove impurities without affecting the normal operation of the guide wheel assembly 7013.

[0043] Embodiment three: as Figures 3-6As shown, the outer peripheral surface of the sleeve assembly 501 is fixedly connected with a display assembly 5013, the rear side of the display assembly 5013 is fixedly connected with an air pressure sensor 5014, the air pressure sensor 5014 is located on the inner side of the sleeve assembly 501 and is used to detect the gas pressure in the sleeve assembly 501, and the inside of the sleeve assembly 501 is inserted with a guide rod mechanism 6, the main body of the guide rod mechanism 6 is a cylindrical structure, and the guide rod mechanism 6 passes through the sleeve assembly 501 upwards, the bottom end surface of the guide rod mechanism 6 is fixedly connected with a second piston plate 601, and the outer peripheral surface of the second piston plate 601 is also fixedly connected with a second sealing ring 6011, the second piston plate 601 and the first piston plate 5011 together constitute a compression structure for the gas in the sleeve assembly 501, the outer peripheral surface of the guide rod mechanism 6 is fixedly connected with a blocking plate assembly 6012, the main body of the blocking plate assembly 6012 is a cylindrical structure, and the diameter of the blocking plate assembly 6012 is greater than the diameter of the guide rod mechanism 6, the outer peripheral surface of the guide rod mechanism 6 is also provided with an external thread, and the external thread is screwed with a nut assembly 6013, the inside of the longitudinal sliding groove provided at the front end of the guide support 2 is installed with a mounting support 7, the mounting support 7 is sleeved on the outer side of the guide rod mechanism 6 and located above the blocking plate assembly 6012, and the mounting support 7 is limited by the nut assembly 6013, the mounting support 7 is provided with two, and the inner side of the two mounting supports 7 is also fixedly connected with a mounting support plate 7011, the inside of the mounting support plate 7011 and the mounting support 7 is provided with a through hole, and the inside of the through hole is inserted with a guide shaft assembly 7012, the inside of the guide shaft assembly 7012 is provided with a through hole matched with the guide rod mechanism 6, and the guide shaft assembly 7012 is provided with two, the inner side of the two guide shaft assemblies 7012 is rotatably connected with a guide wheel assembly 7013, and the outer side of the guide wheel assembly 7013 passes through a rolled steel piece 7014.

[0044] In this embodiment, when different specifications of rolled steel pieces 7014 are needed to be adapted during use, the height adjustment system is started, the adjusting push rod 5 fixed in the longitudinal groove in the guide support 2 receives a control signal, the top output end thereof protrudes upwards through the through hole in the bottom end of the sleeve assembly 501, pushes the first piston plate 5011 in the inside of the sleeve assembly 501 to move upwards, the first sealing ring 5012 fixed on the outer peripheral surface of the first piston plate 5011 tightly abuts against the inner wall of the sleeve assembly 501, so that the space in the inside of the sleeve assembly 501 separated by the first piston plate 5011 has good airtightness, and as the first piston plate 5011 rises, the gas above it is compressed and the air pressure gradually increases.

[0045] The compressed gas inside the sleeve assembly 501 transmits pressure to the second piston plate 601 fixedly connected to the bottom end of the guide rod mechanism 6, and the second sealing ring 6011 on the outer periphery of the second piston plate 601 also ensures effective transmission of gas pressure. Under the action of gas pressure, the second piston plate 601 drives the guide rod mechanism 6 to move upward, and the guide rod mechanism 6 penetrates the sleeve assembly 501 to extend upward. The blocking plate assembly 6012 fixed to the outer periphery of the guide rod mechanism 6 rises synchronously with the guide rod mechanism 6, and the diameter of the blocking plate assembly 6012 is greater than that of the guide rod mechanism 6, thereby supporting the erecting support 7;

[0046] The erecting support 7 in the longitudinal sliding groove at the front end of the guide support 2 is sleeved outside the guide rod mechanism 6 and located above the blocking plate assembly 6012. When the erecting support 7 drives the inner fixedly connected mounting plate 7011, guide shaft assembly 7012 and guide wheel assembly 7013 to rise to a height matching the current rolling piece 7014 specification, the gas pressure sensor 5014 fixed to the front end of the outer periphery of the sleeve assembly 501 detects that the internal gas pressure reaches a preset value and transmits a signal to the display assembly 5013. The display assembly 5013 displays the current gas pressure state. At this time, by rotating the nut assembly 6013 on the outer thread at the top end of the outer periphery of the guide rod mechanism 6, the nut assembly 6013 is tightened downward to firmly fix the erecting support 7 between the blocking plate assembly 6012 and the nut assembly 6013, thereby completing the locking of the height.

[0047] During the entire height adjustment process, the gas pressure sensor 5014 monitors the change of the gas pressure in the sleeve assembly 501 in real time and feeds back data to the display assembly 5013 and the external control system in real time. If the gas pressure fluctuates abnormally, the control system can adjust the output of the push rod 5 in time to ensure the stable lifting of the guide rod mechanism 6 and avoid additional vibration of the guide wheel assembly 7013 due to sudden change of height. This height adjustment method realized by gas pressure transmission can accurately control the height of the guide wheel assembly 7013 to keep it in an adaptive contact state with rolling pieces 7014 of different specifications, thereby solving the problem of narrow application range of existing devices and difficulty in adapting to diversified rolling piece 7014 detection requirements, and ensuring the consistency of detection data under different working conditions through stable support environment.

[0048] Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
