Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Examples
As shown in fig. 1 and 2, the auxiliary tool for casting the tundish in the high-speed steel roll casting comprises an anchor ear 10 fixed on the outer wall of the tundish 1, rotating shafts 11 fixed on two opposite sides of the anchor ear 10 and an auxiliary box 20 for assisting in turning over the tundish 1, wherein the rotating shafts 11 are rotatably connected to the auxiliary box 20 through bearings 12; install the motor 21 that provides the low-speed work of upset power in the auxiliary box 20, fixed mounting has driving gear 22 in motor 21's the pivot, fixed mounting has driven gear 23 with driving gear 22 meshing on the pivot 11, install control motor 21 pivoted control button 24 on the shell of auxiliary box 20.
In the embodiment, the motor 21 is arranged in the auxiliary box 20, and the driving gear 22 is meshed with the driven gear 23 to provide power for turning the tundish 1, so that a hand wheel is prevented from being manually rotated during casting, and the casting efficiency is greatly improved. Only one auxiliary box 20 is arranged, one side opposite to the auxiliary box 20 is provided with a connecting seat which is rotatably connected with the rotating shaft 11, and the tops of the auxiliary box 20 and the connecting seat are both connected with hoisting ropes to help move the tundish 1.
In this embodiment, as shown in fig. 2 and 3, a strip-shaped limiting groove 231 is formed in the side wall of the driven gear 23, the limiting groove 231 is uniformly distributed around the axis of the driven gear 23, a partition 232 is arranged between adjacent limiting grooves 231, a limiting insertion rod 25 is installed in the auxiliary box 20, one end of the limiting insertion rod 25 is inserted into the limiting groove 231, the other end of the limiting insertion rod 25 penetrates through the box body of the auxiliary box 20 and extends to the outside of the auxiliary box 20, and the limiting insertion rod 25 is slidably connected with the box body of the auxiliary box 20.
Because the rotation of the motor 21 is uncontrollable, but the tundish 1 cannot be turned over all at one time in the turning casting process and needs to be cast for multiple times, the turning degree of the tundish 1 is controlled by arranging strip-shaped limiting grooves 231 which are uniformly distributed on the side wall of the driven gear 23, and the length of the limiting groove 231 is the degree that the motor 21 can control the turning of the tundish 1 each time; during overturning, the motor 21 rotates to drive the tundish 1 to overturn, the position of the limiting inserted rod 25 in the limiting groove 231 also changes at the moment until the limiting inserted rod 25 reaches the other end from one end of the limiting groove 231, at the moment, the driven gear 23 cannot rotate any more due to the limitation of the spacer 232 between the adjacent limiting grooves 231, and the tundish 1 stops rotating from the above, so that the control of the overturning angle of the tundish 1 can be realized; when the tundish 1 needs to be turned over, the limit inserted rod 25 can be pulled outwards to be separated from the limit groove 231 because the limit inserted rod 25 is connected with the body of the auxiliary box 20 in a sliding manner, the driven gear 23 can continue to rotate after losing the limit of the limit inserted rod 25, and the limit inserted rod 25 is inserted back to control the next turning.
Further, as shown in fig. 4, a guide tube 26 is disposed on an inner wall of the auxiliary box 20, and the limit insert rod 25 is slidably disposed in the guide tube 26. Because the limiting inserted rod 25 needs to be accurately butted when being inserted back into the limiting groove 231, the guide pipe 26 can provide a guiding function for the movement of the limiting inserted rod 25, and the inserting precision of the limiting inserted rod 25 is ensured.
Further, as shown in fig. 4, a spring 27 is arranged in the guide tube 26, one end of the spring 27 is fixed to the inner wall of the guide tube 26, and the other end is fixedly connected to the outer wall of the limit inserted rod 25. When outwards pulling out spacing inserted bar 25 and making it break away from spacing groove 231, spring 27 is compressed, stores elastic potential energy, inserts spring 27 back spacing groove 231 when carrying out spacingly again when needs, only need loosen the hand and pass through spring 27 alright realization and reset, has improved the convenience of control greatly.
In addition, the transmission ratio of the driving gear 22 to the driven gear 23 is greater than six. Firstly, the turning control of the tundish 1 needs to be stable and slow, in addition, the rotating speed of the motor is higher, the transmission ratio of the driving gear 22 and the driven gear 23 is increased, and the turning speed of the tundish 1 can be reduced, so that the turning control stability of the tundish 1 is ensured, and the control reaction time of the limiting inserted rod 25 can be prolonged.
Secondly, as shown in fig. 2, the both sides of pivot 11 are equipped with supplementary stable axle 13, the one end of supplementary stable axle 13 is fixed on staple bolt 10, the box sliding connection of the other end and auxiliary box 20, be equipped with the ring channel 28 with supplementary stable axle 13 adaptation on the box outer wall of auxiliary box 20, the cross-section of ring channel 28 is the disc that the major arc constitutes, supplementary stable axle 13 is spherical with the sliding connection end of ring channel 28. Because the molten steel quality of the tundish 1 and the inside of the tundish is very large, the rotating shaft 11 can be bent or broken, safety accidents can be caused, the tundish 1 can be prevented from toppling after the rotating shaft 11 is bent or broken by arranging the auxiliary stabilizing shaft 13 and arranging the sliding connecting end of the auxiliary stabilizing shaft 13 and the annular groove 28 to be spherical, and meanwhile, the tundish 1 can be kept stable when being turned over.
