[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1and Figure 4 This utility model provides a technical solution for a hot rolling device for a section steel production line: a hot rolling device for a section steel production line includes a motor 1, a hot rolling device body 2, and an anti-reverse device 3. The output end of the motor 1 is connected to the anti-reverse device 3. The anti-reverse device 3 is embedded in the hot rolling device body 2 and is slidably connected inside the hot rolling device body 2. The anti-reverse device 3 includes a rotating shaft 31, a snap-fit device 32, and a perforated disc 33. The left and right edges of the rotating shaft 31 are fixedly connected to the inner wall of the hole of the perforated disc 33. The front end of the rotating shaft 31 is fixedly connected to the snap-fit device 32 at the connection point of the perforated disc 33, and the snap-fit device 32 is slidably connected to the surface of the perforated disc 33.
[0026] Please see Figure 2 The hot rolling device body 2 has a hot rolling device shaft housing 21 installed at the bottom. The inner wall surface of the hot rolling device shaft housing 21 is smooth and covered with lubricating oil to ensure that the equipment is not damaged during operation and to improve the stability of the equipment.
[0027] Please see Figure 3 The hot rolling device shaft housing 21 includes an inner wall gear 211 and a perforated shaft housing 212. The perforated shaft housing 212 has an inner wall gear 211 on its inner wall to increase the flexibility of rotation.
[0028] Please see Figure 6 The buckling device 32 includes a toothed saw buckling block 321 and a spring 322. The toothed saw buckling block 321 is fixedly connected to the rotating shaft 31 through the spring 322, so that the toothed saw buckling block 321 can move up and down when rotating, making the equipment more flexible.
[0029] The perforated disc 33 has a positioning block 331 at its upper end. The positioning block 331 clamps the toothed saw buckle block 321, allowing the toothed saw buckle block 321 to slide and connect inside the positioning block 331, stabilizing the direction of the toothed saw buckle block 321 and preventing it from falling off.
[0030] The toothed saw buckle block 321 at the upper end of the toothed saw buckle block 321 and the inner wall gear 211 have the same module, so that the rotation speed is stable.
[0031] When in use, as the motor 1 rotates, it drives the rotating shaft 31 of the anti-reverse device 3 to rotate, which in turn drives the perforated disc 33 to rotate together;
[0032] Under the constraint of the positioning block 331, the toothed saw buckle block 321 drives the inner wall gear 211 of the inner wall of the hot rolling device shaft housing 21 to rotate and connect, causing the hot rolling device body 2 to rotate. When the friction is large, a reverse torque occurs. Due to the tilting and sliding of the inner wall gear 211 and the toothed saw buckle block 321, as the spring 322 is compressed, the sliding connection is established, and the hot rolling device body 2 stops rotating.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
