Description

Technical Field

[0001] The utility model relates to an online monitoring device for axial roller shifting of a steering roller of an annealing furnace, and belongs to the field of cold rolling annealing production equipment in the metallurgical industry. Background Art

[0002] Annealing furnace is a common annealing equipment in cold rolling mills, and steering rollers are installed inside. After long-term use, the steering rollers in the continuous annealing production line often move axially from the transmission side to the operating side due to the wear and loosening of the bearing cone sleeve. Generally, the steering rollers in the annealing furnace are designed as convex rollers. If the abnormal rotation of the steering rollers is not discovered in time, the axial deviation will cause the strip to move relative to the roller surface during operation and cause scratches, affecting the surface quality of the strip. In severe cases, it will cause the strip to deviate during production, which is easy to cause edge cracking defects, and even cause serious accidents such as strip breakage in the furnace.

[0003] When the steering roller is axially offset, the common maintenance method is to use a hammer to hit the axially offset steering roller or weld a bracket on the furnace wall, and then use a jack to reset the roller. Due to the weight of the roller and the impact on the strip, this maintenance work is inefficient, requires a lot of manpower and repair time, and will cause damage to the appearance of the furnace wall.

[0022] In this embodiment, refer to the attached Figure 1 , 2 3. The annealing furnace steering roller axial shifting online monitoring device mainly includes a monitoring rod 2, a monitoring rod guide sleeve 3, a square seal ring 4, a nut 5, a screw A6, a flag 7, a flagpole 8, a fixing plate 9, an adjustment plate 10, a limit pin 11, a shaft sleeve 12, a limit plate 13, a tension spring 15, a spring fixing ring 16, a support plate 17, a screw B18, and a screw C19. The square seal ring 4 is arranged inside the monitoring rod guide sleeve 3. The front end of the monitoring rod 2 passes through the monitoring rod guide sleeve 3 and the square seal ring 4. The rear end of the monitoring rod 2 is sleeved with a shaft sleeve 12. Two limit pins 11 are clamped on both sides of the shaft sleeve 12, and the limit pin 11 is fixed on the monitoring rod 2. The lower end of the flagpole 8 is welded on the shaft sleeve 12, and the upper end of the flagpole 8 is provided with a flag 7. One side of the fixing plate 9 has a 5mm long slot, which clamps the flagpole 8. The other side of the fixing plate 9 is fixed to the through slot of the adjustment plate 10 by nuts 5 and screws A6. The through slot is 10mm long. The adjustment plate 10 is welded to the upper end of the support plate 17. The lower end of the support plate 17 is located on the monitoring rod guide sleeve 3 and is fixed to the bearing sleeve end cover 14 by screws B18. The limit plate 13 is located below the monitoring rod 2. There is a spring fixing ring 16 on the limit plate 13, which is connected to the spring fixing ring 16 on the flagpole 8 by a tension spring 15. The limit plate 13 is fixed to the bearing sleeve end cover 14 by screws C19.

[0023] The installation and use of the device are as follows:

[0024] Refer to the attached Figure 1 , 23. During installation, first fix the support plate 17 on the bearing sleeve end cover 14 with screws B18. After fixing the support plate 17 and the adjustment plate 10, drill a hole on the bearing sleeve end cover 14 below the support plate 17, install the monitoring rod guide sleeve 3 with the square sealing ring 4, and then insert the monitoring rod 2 into the monitoring rod guide sleeve 3 and the square sealing ring 4. The front end of the monitoring rod 2 presses against the outer ring positioning sleeve 1, and the rear end is installed with the shaft sleeve 12. The two sides of the shaft sleeve 12 are limit pins 11. A flagpole 8 is welded on the sleeve 12, and a flag 7 is sleeved on the upper end of the flagpole 8. After the monitoring pole 2 is fixed in position, the fixing plate 9 is installed on the through slot of the adjusting plate 10 using screws A6 and nuts 5, and the front end slot of the fixing plate 9 clamps the flagpole 8; the limit plate 13 is fixed to the bearing sleeve end cover 14 using screws C19, and the limit plate 13 is below the monitoring pole 2; spring fixing rings 16 are respectively installed on the flagpole 8 and the limit plate 13, and the two spring fixing rings 16 are connected using a tension spring 15.

[0025] In normal state, there is no need to adjust the position between the fixed plate 9 and the adjustment plate 10. The length of the front end slot of the fixed plate 9 is 5mm. When the steering roller has a roll shifting phenomenon, the outer ring positioning sleeve 1 also moves in the same direction as it, and at this time it will move in one direction against the monitoring rod 2, and the flagpole 8 will also move with the monitoring rod 2. When the displacement exceeds 5mm, it means that the axial roll shifting phenomenon has occurred at this time, and the flagpole 8 and the flag 7 will exceed the length of the slot of the fixed plate 9. Under the self-gravity of the flagpole 8 and the flag 7 and the tension of the tension spring 15, the position of the flagpole 8 and the flag 7 will move to the limit plate 13. At this time, the direction of the flag 7 changes and it is located at the limit plate 13 as an intuitive sign, indicating that the axial roll shifting phenomenon has occurred.

[0026] When the steering roller expands and contracts with the weather, the outer ring positioning sleeve 1 also has the same phenomenon. At this time, it is necessary to readjust the position of the monitoring rod 2. After the monitoring rod 2 is fixed, adjust the position of the fixing plate 9 and the adjusting plate 10, and use the screw 6 and the nut 5 to fix the fixing plate 9 and the adjusting plate 10. The length of the front end slot of the fixing plate 9 is 5mm. When the steering roller has a roll shifting phenomenon, the outer ring positioning sleeve 1 also moves in the same direction as it, and at this time it will move in one direction against the monitoring rod 2, and the flagpole 8 will also move with the monitoring rod. When the displacement exceeds 5mm, it means that the axial roll shifting phenomenon has occurred at this time, and the flagpole 8 and the flag 7 will exceed the length of the slot of the fixing plate 9. Under the self-weight of the flagpole 8 and the flag 7 and the tension of the tension spring 15, the position of the flagpole 8 and the flag 7 will move to the limit plate 13. At this time, the direction of the flag 7 changes and it is located at the limit plate 13 as an intuitive sign, indicating that the axial roll shifting phenomenon has occurred.

[0027] The utility model can monitor the movement of the steering roller under different conditions. If there is any movement, the intuitive flag turns around as a reminder, which can effectively remind the workers to find it at the first time during the inspection, protecting the personal safety of the workers. It can also effectively reduce the expansion of accidents caused by roller shifting problems, effectively reduce the number of shutdowns, ensure the heating capacity of the heating furnace, and reduce the impact on the production line; it can also effectively reduce the number of times the steering roller is reinstalled and reduce the damage to the appearance of the furnace wall.
