Description

Technical Field

[0001] This invention relates to the field of metallurgical equipment testing technology, specifically a high-temperature furnace roller laser testing instrument. Background Technology

[0002] As a core component of metallurgical hot strip rolling production lines, the roundness, straightness, and surface defects of high-temperature furnace rolls directly affect the quality of strip steel products. Therefore, it is necessary to inspect the furnace rolls. Existing high-temperature furnace roll laser inspection equipment mainly consists of an inspection frame, two end supports, a furnace roll rotation drive mechanism, an axial sliding mechanism, and a laser measuring device. During inspection, the furnace roll is hoisted onto the support, and an independent rotary motor drives the furnace roll to rotate. At the same time, an independent feed motor drives the laser measuring device to move along the axial direction of the roll body. The distance data of the roll surface is collected by a laser displacement sensor, and the inspection results are obtained by combining the rotation angle and axial position information. Existing equipment typically uses a constant rotation speed to drive the furnace rollers. However, laser displacement sensors are photoelectric discrete sampling devices, and their detection accuracy depends on hardware parameters such as the sampling frequency and the energy integration time of the laser spot. When the outer diameter of the furnace roller increases, the circumferential linear velocity of the roller surface increases synchronously with the outer diameter. On the one hand, this leads to a shorter residence time of the laser spot at a single point on the roller surface, which cannot meet the energy integration requirements and is prone to signal loss and data jumps. On the other hand, it leads to an increase in the arc length interval of the sampling points in the circumferential direction, making it easy for millimeter-level tiny defects to fall into the sampling gap, resulting in missed detections and thus a high detection deviation of the furnace rollers. Therefore, this invention provides a high-temperature furnace roller laser detector to solve the above-mentioned problems. Summary of the Invention

[0003] The purpose of this invention is to provide a high-temperature furnace roller laser detector to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A high-temperature furnace roller laser inspection instrument includes an inspection frame, with side supports fixedly installed at both ends of the top of the inspection frame. Two support wheels are rotatably installed on each of the two side supports. A base plate is slidably installed on the top of the inspection frame. A laser measuring frame is fixedly installed at both ends of the top of the base plate. A control console is fixedly installed on the side wall of the inspection frame.

The top of the transmission groove extends to the position of the support wheel inside the side support frame. A transmission belt is installed inside the transmission groove. One end of the transmission belt is fitted onto the transmission wheel, and the other end of the transmission belt is fitted onto the drive shaft of the support wheel.

[0006] As a further embodiment of the present invention, a plurality of drive gears are provided, and the plurality of drive gears are fixedly installed at intervals on the side wall of the drive rod. The size of the drive gears gradually decreases from the side closer to the control console to the side farther from the control console. The number of driven gears is matched with the number of drive gears, and the size of the driven gears gradually increases from the side closer to the control console to the side farther from the control console.

[0007] As a further embodiment of the present invention, the adjusting component includes a movable sleeve, which is movably fitted onto the driven rod. The driven gear is fixedly installed at intervals on the side wall of the movable sleeve. Limiting strips are fixedly installed around the side wall of the driven rod at intervals. A limiting groove is formed on the inner side of the movable sleeve. The limiting groove and the limiting strip allow the movable sleeve to slide on the driven rod.

[0008] As a further embodiment of the present invention, the adjusting component further includes a main control plate, which is rotatably mounted on the outer wall of the movable sleeve. A main adjustment plate is mounted on the top of the main control plate, and a main push plate and an auxiliary push plate are fixedly mounted on the bottom two sides of the main adjustment plate, respectively. Both the main push plate and the auxiliary push plate are stepped plates, and the number of steps of the main push plate and the auxiliary push plate is adapted to the number of the driving gear and the driven gear. The stepped surfaces of the main push plate and the auxiliary push plate correspond to each other, and the stepped positions of the main push plate and the auxiliary push plate are inclined guide slopes. The top of the main control plate is located between the main push plate and the auxiliary push plate. A through groove is opened on the side wall of the main control plate, and the width of the through groove is adapted to the thickness of the auxiliary push plate. The side wall of the main adjustment plate is fixedly connected to the lifting component.

[0009] As a further embodiment of the present invention, the lifting component includes an inner adjustment cavity, which is opened on both sides inside the side support frame. The main adjustment plate is movably installed in one of the inner adjustment cavities, and a locking component is movably installed in the other inner adjustment cavity. The locking component and the lifting component are fixedly connected to each other. The bottom of the inner adjustment cavity is provided with an auxiliary adjustment groove that communicates with the adjustment groove at the position corresponding to the main control plate.

[0010] As a further embodiment of the present invention, the locking fastener includes a limiting plate, which is a "U"-shaped plate. The limiting plate is slidably installed in the inner adjusting cavity. The limiting plate and the pressure plate are fixedly connected to each other. A pushing plate is installed at the bottom of the limiting plate. The pushing plate is an "L"-shaped plate. The end of the pushing plate away from the inner side of the inner adjusting cavity slides through the side wall of the side support and extends to the outside of the side support. A locking block is fixedly installed at the top of the pushing plate near the control console. The locking block is located at the bottom of the limiting plate near the control console. Locking grooves are spaced apart on the inner side wall of the limiting plate. A locking strip is fixedly installed on the side wall of the locking block. The locking block is slidably installed in the limiting plate through the locking strip and the locking groove. An auxiliary spring is fixedly installed on the side of the pushing plate near the control console. The end of the auxiliary spring away from the pushing plate is fixedly installed on the inner wall of the inner adjusting cavity.

[0011] As a further embodiment of the present invention, a clearance groove is provided on the side of the lock groove near the control console. The clearance groove is an inclined groove and is interconnected with the lock groove. The clearance groove between two adjacent lock grooves forms a cone shape at the end near the control console, and the lock bar is cone-shaped on the side away from the control console.

[0012] As a further embodiment of the present invention, the inside of the testing frame is provided with a moving groove, the moving plate is slidably installed on the inner side of the moving groove, and a sliding groove communicating with the moving groove is provided at the top center of the testing frame. The top of the moving plate passes through the sliding groove and is fixedly connected to the bottom of the base plate.

[0013] As a further embodiment of the present invention, guide grooves are provided on both sides of the top of the detection frame, and guide rods are fixedly installed on the inner side of the guide grooves. Guide plates are slidably installed on the guide rods, and the top of the guide plates and the bottom of the base plate are fixedly connected to each other.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. When the detector of the present invention is used, the vertical displacement is generated by the outer diameter of the furnace roller pressing the pressure plate. The vertical displacement is then converted into the axial movement of the movable sleeve through the stepped guide slope structure of the main adjustment plate and the main control plate. This allows for switching between the driving gear and driven gear pairs with different transmission ratios, automatically realizing the gear adjustment that "the larger the outer diameter of the furnace roller, the slower the rotation speed". This ensures that the linear velocity of the roller surface of furnace rollers with different outer diameters can be adapted to the sampling frequency and spot integration time requirements of the laser sensor, improving the circumferential sampling density and signal quality adaptability, and reducing the occurrence of missed detection of small defects and signal loss in large-size rollers. 2. When the detector of the present invention is used, the drive rod drives the moving plate, the base plate and the laser measuring frame to move axially through the screw transmission. On the other hand, the drive rod drives the support wheel and the furnace roller to rotate through the transmission assembly composed of the drive gear, the driven gear, the transmission wheel and the transmission belt, so as to realize the synchronization of the furnace roller rotation and the laser scanning. Compared with the dual motor electrical interlock scheme, it effectively avoids the problem of invalid detection caused by program failure and component failure, such as the laser device being stationary and the furnace roller running alone. Moreover, the drive rod and the support wheel rotate synchronously. When the laser measuring frame detects a defect and stops moving, the furnace roller stops rotating synchronously. The defect position is accurately corresponding, which is convenient for subsequent maintenance operations. 3. When the detector of the present invention is in use, when the base plate is in the detection start position, the side wall presses the push plate, which drives the locking block and locking bar to exit the locking groove of the limit plate. The lifting part is in the unlocked state and can complete the gear adjustment according to the outer diameter of the furnace roller. After the base plate leaves the start position and enters the scanning stroke, the push plate is reset under the action of the auxiliary spring, and the locking bar is locked into the corresponding locking groove, rigidly locking the vertical position of the limit plate and the pressure plate, thereby locking the meshing position of the drive gear and the driven gear. This can avoid gear jumps and speed fluctuations caused by furnace roller vibration and equipment resonance during the detection operation, and improve the continuity and stability of the detection data.

[0025] 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.

[0026] Please see Figures 1-9In this embodiment of the invention, a high-temperature furnace roller laser inspection instrument includes an inspection frame 1. Side support frames 3 are fixedly installed at both ends of the top of the inspection frame 1. Two support wheels 4 are rotatably installed on each of the two side support frames 3. The support wheels 4 on the side support frames 3 at both ends of the inspection frame 1 can provide rotational support for both ends of the furnace roller. A base plate 9 is slidably installed on the top of the inspection frame 1. Laser measuring frames 11 are fixedly installed at both ends of the top of the base plate 9. The laser measuring frames 11 are located on both sides of the furnace roller, and laser inspection is performed on the surface of the furnace roller through the laser measuring frames 11. A moving groove 13 is opened inside the inspection frame 1. A moving plate 10 is slidably installed on the inner side of the moving groove 13. A sliding groove 8 communicating with the moving groove 13 is opened at the middle of the top of the inspection frame 1. The top of the moving plate 10 passes through the sliding groove 8 and is fixedly connected to the bottom of the base plate 9. A control console 2 is fixedly installed on the side wall of the testing frame 1. The control console 2 integrates an operation panel, control equipment, and a drive motor. A drive rod 14 is fixedly installed on the output shaft of the drive motor. The end of the drive rod 14 away from the drive motor extends into the moving groove 13. The end of the drive rod 14 away from the drive motor is rotatably installed on the inner wall of the moving groove 13. A spiral groove is provided on the outer wall of the inner side of the drive rod 14 located in the moving groove 13. The moving plate 10 is slidably installed on the drive rod 14. A spiral pattern is provided on the inner side of the moving plate 10 corresponding to the position of the drive rod 14. By rotating the drive rod 14 in conjunction with the spiral groove on the side wall of the drive rod 14 and the spiral pattern on the inner wall of the moving plate 10, the moving plate 10 can be moved and adjusted within the moving groove 13, thereby driving the substrate 9 to move on the top of the testing frame 1. The control panel on console 2 is electrically connected to the control device for inputting control commands. The control device is electrically connected to the driver of the drive motor for controlling the start, stop, speed and direction of the drive motor. The control device is also electrically connected to the laser measuring frame 11 for receiving the roller surface distance data collected by the laser measuring frame 11, and calculating the detection result of the furnace roller based on the speed information of the drive motor and the axial position information of the substrate 9.

[0027] The laser measuring frame 11 includes a column, a mounting base, and a laser displacement sensor. The column is fixed to the top of the base plate 9. The mounting base is slidably mounted on the column and can be finely adjusted and locked in the vertical direction. The laser displacement sensor is fixed on the mounting base. The laser displacement sensors on the two laser measuring frames 11 are respectively aligned with the roller surfaces on both sides of the furnace roller to collect roller surface distance data. The laser displacement sensor is electrically connected to the control equipment in the control console 2 through a cable to transmit the collected roller surface distance data to the control equipment for processing in real time.

[0028] A transmission assembly is installed on the inner side of the inspection frame 1 near the control console 2. One end of the transmission assembly is movably connected to the drive rod 14, and the other end of the transmission assembly is movably connected to the support wheel 4 on the corresponding side support frame 3. Through the rotation of the drive rod 14, the support wheel 4 is rotated under the transmission of the transmission assembly, which in turn drives the furnace roller to rotate. This allows the substrate 9 to move while driving the laser measuring frame 11, and also to drive the furnace roller to rotate synchronously through the transmission assembly. This allows the laser measuring frame 11 to perform all-round inspection of the side wall of the furnace roller. Since the rotation of the drive rod 14 is synchronized with the rotation of the support wheel 4, when the laser measuring frame 11 detects a defect and stops moving, the furnace roller stops rotating synchronously. At this time, the detection area corresponding to the laser measuring frame 11 is the location of the furnace roller defect. The location of the furnace roller defect can be marked according to this working state for subsequent repair and other operations. The top two sides of the test frame 1 are provided with guide grooves 6. Guide rods 7 are fixedly installed inside the guide grooves 6. Guide plates 12 are slidably installed on the guide rods 7. The top of the guide plates 12 and the bottom of the substrate 9 are fixedly connected to each other. The movement of the substrate 9 is limited by the guide rods 7 in the guide grooves 6 on both sides and the guide plates 12 at the bottom of the substrate 9 to prevent the substrate 9 from shifting. A lifting component is installed on the side support frame 3 near the side of the inspection frame 1. The lifting component is installed on the side support frame 3 at the end away from the inspection frame 1. An adjusting component is installed on the transmission component. The adjusting component and the lifting component are movably connected to each other. The furnace roller is installed on two support wheels 4. One end of the furnace roller will press on the lifting component, causing the lifting component to drop under pressure, which in turn drives the adjusting component to adjust, thereby adjusting the transmission speed of the transmission component. This allows the rotation speed of the furnace roller driven by the support wheels 4 to be adapted to the outer diameter of the furnace roller. This effectively ensures that the time for a single point on the outer wall of furnace rollers of different specifications to stay in the scanning area of ​​the laser measuring frame 11 is controlled within a specified range. This allows the laser measuring frame 11 to fully scan the outer wall state of furnace rollers of different specifications, avoiding the situation where the single point stay time is too short due to the furnace roller specification being too large at the same rotation speed.

[0029] The transmission assembly includes an adjustment groove 17, which is located inside the detection frame 1 near the control console 2. A drive rod 14 is fixedly installed inside the adjustment groove 17 with a drive gear 18. A driven rod 19 is rotatably installed on one side of the adjustment groove 17. The driven rod 19 is located below the support wheel 4. A driven gear 22 that meshes with the drive gear 18 is installed on the side wall of the driven rod 19. A transmission wheel 20 is fixedly installed on the end of the driven rod 19 near the control console 2. A transmission groove 25 is provided on the side wall of the adjustment groove 17 near the control console 2. The top of the transmission groove 25 extends to the inside of the side support 3 corresponding to the position of the support wheel 4. A transmission belt 26 is installed inside the transmission groove 25. One end of the transmission belt 26 is fitted onto the transmission wheel 20, and the other end of the transmission belt 26 is fitted onto the drive shaft of the support wheel 4. When the drive rod 14 rotates, the driven rod 19 drives the support wheel 4 to rotate through the transmission wheel 20 and the transmission belt 26 via the transmission wheel 20 and the transmission belt 26, thereby driving the furnace roller on the support wheel 4 to rotate synchronously. Several drive gears 18 are provided, and each drive gear 18 is fixedly mounted at intervals on the side wall of the drive rod 14. The size of the drive gears 18 gradually decreases from the side closer to the control console 2 to the side farther away from the control console 2. The number of driven gears 22 is matched with the number of drive gears 18, and the size of the driven gears 22 gradually increases from the side closer to the control console 2 to the side farther away from the control console 2. The adjusting component includes a movable sleeve 21, which is movably fitted onto the driven rod 19. The driven gears 22 are fixedly mounted at intervals on the side wall of the movable sleeve 21, and can slide on the driven rod 19 for adjustment. Limiting strips 28 are fixedly mounted at intervals around the side wall of the driven rod 19. A limiting groove 27 is provided on the inner side of the sleeve 21. The inner diameter of the limiting groove 27 is adapted to the limiting strip 28. The limiting groove 27 and the limiting strip 28 allow the movable sleeve 21 to slide on the driven rod 19 and drive the driven rod 19 to rotate synchronously. In the initial state, the driving gear 18 and the driven gear 22 near the control console 2 are meshed with each other. At this time, the driven gears 22 at other positions on the side wall of the movable sleeve 21 are misaligned with the driving gear 18 on the drive rod 14. As the movable sleeve 21 moves on the driven rod 19, the initially meshed driving gear 18 and driven gear 22 will be misaligned, and at the same time, the next driving gear 18 and driven gear 22 will mesh, thereby completing the speed regulation.

[0030] The adjusting component also includes a main control plate 23, which is rotatably mounted on the outer wall of the movable sleeve 21. The main control plate 23 can only rotate on the outer wall of the movable sleeve 21. A main adjustment plate 31 is installed at the top of the main control plate 23. A main push plate 35 and an auxiliary push plate 36 are fixedly installed on the bottom two sides of the main adjustment plate 31, respectively. Both the main push plate 35 and the auxiliary push plate 36 are stepped plates. The number of steps in the main push plate 35 and the auxiliary push plate 36 is adapted to the number of the driving gear 18 and the driven gear 22. The stepped surfaces of the main push plate 35 and the auxiliary push plate 36 correspond to each other. The stepped positions of the main push plate 35 and the auxiliary push plate 36 are inclined guide slopes. The top of the main control plate 23 is located between the main push plate 35 and the auxiliary push plate 36. A through groove 24 is opened on the side wall of the main control plate 23. The width of the through groove 24 is adapted to the thickness of the auxiliary push plate 36. When the main push plate 23 is in the middle, the main push plate 23 can rotate freely. When the adjustment plate 31 descends, the main push plate 35 and the auxiliary push plate 36 descend synchronously. When the stepped guide slope of the main push plate 35 contacts the top of the main control plate 23, the main control plate 23 is moved by the pressure of the inclined surface until the inclined surface of the next stepped guide slope is pressed. When the main control plate 23 moves, the bottom of the auxiliary push plate 36 will be inserted into the through groove 24 and will not block the movement of the main control plate 23 towards the control console 2. When the main adjustment plate 31 moves upward, the inclined surface of the stepped guide slope on the auxiliary push plate 36 will press the top of the inner side of the through groove 24, causing the main control plate 23 to move in the opposite direction under pressure, thereby completing the reciprocating movement adjustment of the main control plate 23. Thus, the movable sleeve 21 can be moved by the through groove 24. The side wall of the main adjustment plate 31 is fixedly connected to the lifting component. The lifting component includes an auxiliary groove 5 and an inner adjustment cavity 29. The auxiliary groove 5 is formed on the side walls of two side supports 3, which are close to each other. A pressure plate 15 is slidably installed on the top of the auxiliary groove 5 on the side closer to the control console 2. A spring telescopic rod 16 is fixedly installed on the bottom of the pressure plate 15. The end of the spring telescopic rod 16 away from the pressure plate 15 is fixedly installed on the bottom of the auxiliary groove 5. The inner adjustment cavity 29 is formed on both sides of the side support 3, corresponding to the pressure plate 15. A side groove 3 is formed through the side wall of the auxiliary groove 5 near the inner adjustment cavity 29. 0. The main adjustment plate 31 is movably installed in one of the inner adjustment cavities 29, and the main adjustment plate 31 is fixedly connected to the pressure plate 15. A locking fastener is movably installed in the other inner adjustment cavity 29. The locking fastener is fixedly connected to the pressure plate 15. The position of the pressure plate 15 can be locked after the furnace roller is installed. The bottom of the inner adjustment cavity 29 is provided with an auxiliary adjustment groove 37 that communicates with the adjustment groove 17, corresponding to the position of the main control plate 23. The main control plate 23 can be moved horizontally through the auxiliary adjustment groove 37. The locking mechanism includes a limiting plate 32, which is a U-shaped plate. The limiting plate 32 is slidably installed in the inner adjusting cavity 29 and can be adjusted up and down within the inner adjusting cavity 29. The limiting plate 32 and the pressure plate 15 are fixedly connected to each other. A pushing plate 33, which is an L-shaped plate, is installed at the bottom of the limiting plate 32. The end of the pushing plate 33 away from the inner side of the inner adjusting cavity 29 slides through the side wall of the side support 3 and extends to the outside of the side support 3. The top of the pushing plate 33 is close to the control console. A locking block 38 is fixedly installed on one side of the limiting plate 32. The locking block 38 is located at the bottom of the limiting plate 32 near the control console 2. Lock grooves 39 are spaced apart on the inner side wall of the limiting plate 32. A locking bar 41 is fixedly installed on the side wall of the locking block 38. The locking block 38 is slidably installed in the limiting plate 32 through the locking bar 41 and the locking groove 39. An auxiliary spring 34 is fixedly installed on the side of the push plate 33 near the control console 2. The end of the auxiliary spring 34 away from the push plate 33 is fixedly installed on the inner wall of the inner adjusting cavity 29. In the initial state, the substrate 9 and the laser measuring frame 11 are located at the top of the detection frame 1, near the control console 2. At this time, the side wall of the substrate 9 will squeeze the push plate 33, causing the push plate 33 to contract inward into the adjusting cavity 29 under pressure, thereby driving the locking block 38 to move out of the inner side of the limiting plate 32, thus releasing the locking of the limiting plate 32. At this time, the two ends of the furnace roller are placed between the two support wheels 4 on the side support frame 3, so that the ends of the furnace roller press on the pressure plate 15. Depending on the outer diameter of the furnace roller, the downward movement of the pressure plate 15 after being pressed varies. The adjustment mechanism causes the main adjustment plate 31 and the limiting plate 32 to descend synchronously. When the base plate 9 moves the laser measuring frame 11 on the detection frame 1, the base plate 9 and the push plate 33 separate. The push plate 33 will move the locking block 38 into the limiting plate 32 through the auxiliary spring 34, so that the locking bar 41 is inserted into the locking groove 39 on the inner side of the limiting plate 32, thus locking the position of the limiting plate 32. This locking can prevent fluctuations during the furnace roller detection operation from affecting the furnace roller speed and ensure the stability of the detection operation.

[0031] The lock groove 39 has a clearance groove 40 on the side near the control panel 2. The clearance groove 40 is an inclined groove. The clearance groove 40 and the lock groove 39 are interconnected. The clearance groove 40 between two adjacent lock grooves 39 forms a cone shape at the end near the control panel 2. The lock bar 41 is cone-shaped on the side away from the control panel 2. When the limiting plate 32 is moved to a non-standard position by the lock bar 41 and the clearance groove 40, the lock bar 41 can still be inserted into the lock groove 39 to lock the limiting plate 32.

[0032] The working principle of this invention is: When the detector of the present invention is used, during the initial operation, the base plate 9 is located at the top of the detection frame 1 near the control console 2, and the locking parts are pressed, so that the locking parts are in the unlocked state. The two ends of the furnace roller are placed between the two support wheels 4 on the two side support frames 3. At this time, the upper end of the furnace roller will press on the pressure plate 15, so that the pressure plate 15 will move down according to the size of the outer diameter of the furnace roller, thereby driving the adjustment parts to adjust accordingly, so that the movable sleeve 21 moves on the driven rod 19, and the driven gear 22 at the appropriate position meshes with the driving gear 18 on the drive rod 14. At this time, the drive motor in the control console 2 starts and drives the drive rod 14 to rotate, so that the drive rod 14 drives the base plate 9 to move on the detection frame 1 through the moving plate 10.
