Description

Technical Field

[0001] The utility model relates to the field of ladle mechanisms, in particular to a novel sliding plate locking device for the ladle mechanism. Background Art

[0002] The ladle sliding nozzle mechanism is one of the important devices used in the metallurgical industry to control the amount and direction of molten steel outflow, and is mainly used in continuous casting and refining processes. Its main function is to accurately control the flow of molten steel when it flows from the ladle to the tundish or directly into the casting mold, thereby ensuring the quality of castings and production efficiency.

[0003] In the sliding gate mechanism of the ladle, the pouring process of the steel flow is realized by the lower slide block sliding along the upper slide block at a uniform speed to open or close the upper and lower slide blocks. Therefore, the slide block is required to have good high-temperature strength and stability.

[0004] At present, the skateboard shape of the skateboard brick is mostly octagonal or elliptical. After the skateboard brick is installed in the frame of the sliding nozzle mechanism, it needs to be fixed to ensure its stability. The main method is to set positioning corner blocks at the four corners of the frame to press and fix the skateboard. For specific fixing methods, please refer to the utility model patent with application number 2017201803637. This pressing and fixing method has a simple structure, but it is prone to loosening and displacement during actual use. Frequent inspection and adjustment are required to ensure the pressing and fixing effect. The operation is troublesome, and the inspection is not in place, which is prone to steel leakage, and needs to be improved. Utility Model Content

After the top pressing block 24 enters the slot 261, the top pressing inclined surface 241 slides and presses the bottom surface of the slot 261, thereby driving the locking block 26 to slide outward.

[0023] A cylindrical pin 263 is vertically provided on the bottom surface of the locking block 26, and a guide groove slidably connected to the cylindrical pin 263 is provided at a corresponding position in the assembly groove 11. The cylindrical pin 263 and the guide groove provide a sliding guide for the locking block 26 so that it can slide laterally and press against the side of the skateboard brick 12.

[0024] As attached Figure 3 or attached Figure 4As shown, the inner side, outer side, bottom and upper surface of the locking block 26 are all provided with grooves 242, and the contact area between the side of the locking block 26 and the support is reduced by providing the grooves 242, thereby reducing the friction resistance and improving the sliding pressing effect. A square through hole is provided in the middle of the outer end surface of the second support 22, and the square through hole corresponds to the position of the locking block 26.

[0025] The principle of the locking device 02 is as follows: the first support 21 and the second support 22 are in a fixed state in the assembly groove 11, and the spring 25 inside the support provides elastic pressure for the sliding rod in the support, and the sliding rod and the pressing block 24 at its end slide in the support. When the pressing block 24 enters the slot 261 of the locking block 26, the pressing inclined surface 241 slides and presses the bottom surface of the slot 261, driving the locking block 26 to slide outward and press on the side of the skateboard brick 12. This locking and fixing method can apply continuous elastic pressing force to the skateboard brick 12, and the pressing and locking effect is better. The skateboard brick 12 is not easy to loosen, and there is no need to frequently check and adjust the pressing and fixing effect of the skateboard brick 12.

If the locking block 26 is to be released from locking the slide block 12, the cylindrical handle 231 is pushed upward by hand, and the cylindrical handle 231 slides upward in the long notch 222. When it slides to the guide slope 224, the cylindrical handle 231 rotates and slides toward the side of the support step 223, and finally reaches the top of the support step 223, and the cylindrical handle 231 is released. Under the action of the rebound force of the spring 25, the cylindrical handle 231 presses on the step, and the elastic pressure applied to the locking block 26 is released.

[0028] Example 3, see the attached specification Figure 3-4 , which is basically the same as the first embodiment, and the similarities are not repeated here, except that:

[0029] A cross protrusion 31 is provided on the inner end face of the first support 21, and a cross groove 32 is correspondingly provided on the end face of the second support 22. The cross protrusion 31 can be matched and inserted into the cross groove 32 to initially fix the two supports to prevent relative rotation between the two. The edge portion of the first support 21 is provided with a bolt 34 hole along its length direction, and a threaded hole 33 corresponding to the position of the bolt 34 hole is provided on the end face of the second support 22. The threaded hole 33 is a blind hole, and a bolt 34 is installed between the bolt 34 hole and the threaded hole 33.
