Description

Technical Field

[0001] The utility model relates to the technical field of tension roller detection equipment, in particular to a tension roller surface detection device. Background Art

[0002] The bulge on the tension roller surface refers to the phenomenon that the surface of the tension roller protrudes outward due to the influence of various factors during operation. During the long-term operation of the tension roller, the tension roller is affected by factors such as thermal expansion and bending stress, causing the middle part of the roller to deform and protrude outward. In the cold rolling process, due to the high-intensity pressure and friction, the surface of the tension roller will produce a certain degree of plastic deformation, resulting in bulges. This bulge is unevenly distributed and gradually intensifies with the increase of usage time. Once bulges appear on the surface of the tension roller, it will affect the quality of the steel strip. Therefore, in the daily maintenance of the tension roller, it is necessary to detect the flatness of the surface of the tension roller. Since some slight bulges are difficult to distinguish with the naked eye, in many cases, when the surface of the tension roller has slight bulges, it is difficult for the staff to discover it in time, resulting in maintenance omissions, which indirectly affects the quality of the rolled steel strip.

The three-jaw chuck 3 grabs the roller shafts at both ends of the tension roller 4. A movable plate 6 that can be raised and lowered is arranged on the top of the frame 1, and roller surface detection mechanisms are evenly arranged at the lower end of the movable plate 6.

[0020] Preferably, the warning device 13 is a warning light.

[0021] A first hinge plate 14 is provided at the lower end of the base 7, and a second hinge plate 15 is provided at the lower end of one side of the flip plate 8. The first hinge plate 14 and the second hinge plate 15 are hinged by a pin shaft. The connecting rod 9 is provided on the flip plate 8 on the side opposite to the second hinge plate 15. The proximity switch 11 crosses above the base 7. The sensing block 12 is provided at the upper end of the flip plate 8 and faces the sensing end of the proximity switch 11. The alarm 13 is evenly distributed and placed horizontally on the movable plate 6.

[0022] A spring seat 16 is provided on the flip plate 8 at a position corresponding to the sensing block 12. The sensing block 12 is mounted on the spring seat 16. The spring seat 16 allows the sensing block 12 to deform when in contact with the proximity switch 11, thereby preventing the two from being damaged by excessive squeezing.

[0023] Preferably, the detection plate 10 is made of rubber.

[0024] The rack 1 is provided with slide rails 17 on both sides of its bottom plate, the slide rails 17 are provided with sliders 18 , a mounting plate 19 is provided on the top of the sliders 18 , and the equipment seat 2 is mounted on the mounting plate 19 .

[0027] The working principle of the utility model is as follows: the tension roller 5 is placed on the supporting roller 4, and the position of the equipment seat 2 is adjusted according to the specifications of the tension roller 5, so that the three-claw chucks 3 on the equipment seats 2 on both sides are grasped on the roller shafts at both ends of the tension roller 5, and then the lifting cylinder 21 is controlled to start, and the movable plate 6 is adjusted up and down according to the position of the roller surface of the tension roller 5, so that the detection plate 10 can be close to the upper end surface of the tension roller 5. At this time, the connecting rod 9 is arranged tilted, and the flip plate 8 is separated from the sensing end of the proximity switch 11, and then the motor 20 is controlled to start, and the motor 20 will drive the three-claw chuck 3 to rotate, thereby causing the tension roller 5 to rotate along the supporting roller 4. As the tension roller 5 rotates, the detection plate 10 will slide on the surface of the tension roller 5. Once a bulge appears on the surface of the tension roller 5, the detection plate 10 will be lifted, and as the position of the detection plate 10 is raised, the flip plate 8 will flip along the pin axis toward the side of the proximity switch 11, so that the sensing block 12 comes into contact with the sensing end of the proximity switch 11. At this time, the proximity switch 11 is triggered, and it will send a signal to control the alarm 13 to light up, thereby reminding the staff that a bulge has been detected on the surface of the tension roller 5. In order to facilitate the staff to mark the bulge position, the proximity switch 11 will control the warning light 13 to light up while also sending a signal to control the motor 20 to stop. The staff will mark the roller surface where the warning light 13 is on. After marking, start 20 again to allow the tension roller 5 to continue rotating, and then continue the detection work.
