[0001] The utility model relates to the technical field of steel production, in particular to an anti-entanglement steel structure for pinch rollers of a thin slab continuous casting and rolling curling machine. Background Art

[0002] The pinch roller is installed in front of the coiler to guide the head of the steel strip into the coiler chute plate and to guide the steel strip to continue forward into the mandrel of the coiler for coiling. Due to the high temperature of the steel strip, the pinch roller needs to be cooled by spraying during the pinching process. Therefore, it is necessary to install a scraper under the pinch roller to scrape off the water flow on the pinch roller to prevent the water flow from entering the slab. In order to prevent friction between the pinch roller and the scraper, a certain gap is generally reserved between the two, which causes the head of the steel strip to be brought into the gap between the pinch roller and the scraper, causing the steel strip to be entangled on the pinch roller. This kind of fault takes a long time to handle, and generally forces the continuous casting to be stopped, which seriously affects the production rhythm and increases the labor intensity of steel stacking.

[0024] See also Figure 1 and Figure 2The utility model provides a steel structure for preventing the entanglement of the pinch rollers of a thin slab continuous casting and rolling coiling machine. The steel structure for preventing the entanglement of the pinch rollers of the thin slab continuous casting and rolling coiling machine comprises a wiper 1, a pinch roller 3, a pinch roller frame 5, a switching assembly 7 and a flap control member 9. The pinch roller 3 is mounted on the pinch roller frame 5. The wiper 1 is rotatably connected to the pinch roller frame 5 through the switching assembly 7 and is mounted under the pinch roller 3 along the axial direction of the pinch roller 3 while maintaining a preset gap with the outer wall of the pinch roller 3. One end of the flap control member 9 is mounted on the pinch roller frame 5 or the switching assembly 7, and the other end is connected to the wiper 1 to drive the wiper 1 to rotate to adjust the preset gap between the wiper 1 and the pinch roller 3. When the steel strip enters the pinch roller, the flap control component 9 drives the wiper 1 to rotate so that the gap between the wiper 1 and the outer wall of the pinch roller 3 is reduced, so that the steel strip cannot enter the gap. When the steel strip is successfully introduced, the gap between the wiper 1 and the pinch roller 3 is enlarged to prevent the pinch roller 3 from being worn by the wiper 1. Therefore, the flap control component 9 is set to drive the wiper 1 to move and then adjust the gap between the wiper 1 and the pinch roller 3 to prevent the steel strip from entering between the pinch roller 3 and the wiper 1, thereby effectively preventing the steel strip from being entangled and at the same time ensuring that the pinch roller 3 will not be worn under the premise of the wiping effect of the wiper 1.

[0025] Specifically, in this embodiment, the wiper blade 1 includes a connection side 11 and a wiper side 13, and a preset gap is formed between the wiper side and the outer wall of the pinch roller 3. On the same horizontal projection, the connection side 11 is located outside the contour of the pinch roller 3 to form a movement gap and movement space with the pinch roller 3, and the wiper side 13 is located inside the contour of the pinch roller 3 to maintain a positional relationship with the outer wall of the pinch roller 3, and is used to scrape off the water flow on the pinch roller 3. The flap control member 9 is connected to the connection side 11 to drive the wiper blade 1 to rotate to adjust the gap between the wiper blade 1 and the outer wall of the pinch roller 3, so as to prevent the steel belt from being inserted between the pinch roller 3 and the wiper blade 1 and winding around the pinch roller 3. It should be pointed out that the gap can be smaller than the thickness of the steel belt, or it can be zero, so that the steel belt cannot be inserted between the wiper blade 1 and the pinch roller 3.

[0026] Specifically, in this embodiment, the adapter assembly 7 includes a first adapter plate 71 and a second adapter plate 73. The first adapter plate 71 is fixedly connected to the pinch roller frame 5. One end of the second adapter plate 73 is fixedly connected to one end of the first adapter plate 71 away from the pinch roller frame 5, and the other end is rotatably connected to the wiper 1. The first adapter plate 71 and the second adapter plate 73 are detachably connected by bolts to facilitate installation and disassembly. Moreover, the first adapter plate 71 and the second adapter plate 73 are both located on the outside of the wiper 1 and adapted to the outer contour of the wiper 1. The second adapter plate 73 is connected to one end of the wiper 1 to form a curved hook head, so as to form a better fit with the wiper 1 and smoothly control the rotation of the wiper 1 under the drive of the flap control member 9.

[0027] Furthermore, a clearance groove 731 is provided at one end of the second adapter plate 73 connected to the wiper blade 1, and the protruding portion of the end of the wiper blade 1 is installed in cooperation with the clearance groove 731. An elastic buffer 10 is installed between the wiper blade 1 and the groove wall of the clearance groove 731. The two ends of the elastic buffer respectively support the wiper blade 1 and the second adapter plate 73. Installation blind holes are provided on the bottom of the wiper blade 1 and the groove wall of the clearance groove 731. One end of the elastic buffer 10 is embedded in the blind hole opened in the wiper blade 1, and the other end is embedded in the blind hole opened in the clearance groove 731.

[0028] Specifically, in this embodiment, the elastic buffer 10 is a spring. The preload force of the spring supports the wiper blade 1 and the second adapter plate 73 to ensure the gap between the wiper blade 1 and the pinch roller 3, and can be compressed during the rotation of the wiper blade 1 without affecting the movement.

[0029] In addition, an adjusting pressure rod 75 is also installed on the second adapter plate 73, and one end of the adjusting pressure rod 75 away from the second adapter plate 73 abuts against the wiper side 13. The adjusting pressure rod 75 is an adjusting bolt, which presses the wiper blade 1 to prevent the gap between the wiper blade 1 and the pinch roller 3 from being too large. Therefore, the spring and the adjusting pressure rod cooperate to ensure that the gap between the wiper blade 1 and the pinch roller 3 is moderate, not too large and not zero. When the flap control part is not working, the spring force acts, the wiper blade 1 rotates counterclockwise around the axis and separates from the pinch roller 3. The adjusting bolt above the wiper blade 1 is used to keep the degree of separation between the wiper blade 1 and the pinch roller 3 in accordance with the preset gap requirement.

[0030] The flap control member 9 is a cylinder or a push rod. Preferably, the flap control member 9 is a cylinder. When the steel strip tracking system detects that the steel strip will reach the pinch roller 3 in 2 seconds, the control valve of the cylinder is energized, the rodless chamber of the cylinder is energized, and the piston rod is extended, so that the wiper 1 rotates along the fulcrum, causing the wiper 1 to be close to the pinch roller 3, so that the thin and sharp steel strip head cannot be inserted, thereby preventing the occurrence of steel entanglement accidents. After the steel strip is successfully introduced, the cylinder control valve loses power, and the wiper 1 and the pinch roller 3 lose continuous force to reduce the wear between them. In this embodiment, a cylinder is used instead of an oil cylinder because the force of the oil cylinder is relatively large, which will cause scratches on the roller surface of the wiper 1 and the pinch roller 3, while the force of the cylinder is softer than that of the oil cylinder, which has enough force to change the gap between the wiper 1 and the pinch roller 3 without scratching the roller surface of the pinch roller 3.

[0031] As a preferred implementation of this embodiment, the flap control member 9 is fixedly connected to the first adapter plate 71 of the adapter assembly 7 via a mounting bracket 711. The mounting bracket 711 and the first adapter plate 71 are integrally formed, and the arrangement of the mounting bracket 711 can ensure that components at two different positions or directions are connected, thereby ensuring the connection relationship and structural stability between the components.

[0032] The anti-entanglement steel structure of the pinch roller 3 of the thin slab continuous casting and rolling curling machine provided by the utility model drives the wiper plate 1 to move to adjust the gap between the wiper plate 1 and the pinch roller 3 by setting the flap control component 9, thereby preventing the steel strip from entering between the pinch roller 3 and the wiper plate 1, effectively eliminating the entanglement of the steel strip, reducing the failure rate of the production equipment, and at the same time ensuring the wiping effect of the wiper plate 1 without causing wear to the pinch roller 3 and affecting the service life of the pinch roller 3.

[0033] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
