Description

Technical Field

[0001] The utility model relates to the field of ladle turrets, in particular to a casting ladle turret. Background Art

[0002] The ladle turret is the most commonly used device in modern continuous casting, used to transport and support the ladle for pouring. It is typically located between the molten steel receiving span and the pouring span columns. It consists of a base, slewing arm, drive unit, slewing support, emergency drive control system, lubrication system, and anchors.

[0003] The ladle turret uses the rotation of its slewing arm to transport and position the ladle for pouring operations. It can rotate in three different situations: with no ladles on either side, with a ladle on one side, or with ladles on both sides. Each ladle can weigh over 140 tons.

[0004] Prior art CN103586449A provides an adjustable ladle turret. This utilizes an adjustment mechanism consisting of a trapezoidal threaded screw and a matching screw sleeve to adjust the height of the turret arm, ensuring that the two ladles are at the same height. However, if the lifting cylinders of the ladle car in this solution become out of sync or malfunction, the ladles at both ends may be at different heights, leaving the ladle filled with molten steel suspended. This requires adjusting the regulator to extend or shorten the mechanism to raise or lower the turret arm to achieve equilibrium, significantly increasing safety risks.

[0005] Therefore, it is very necessary to provide a casting ladle turret to solve the above technical problems. Utility Model Content

This ensures that the lifting and lowering of the two ladles 4 are always synchronized, improving operational safety. This solves the problem in the prior art where, due to asynchrony or malfunction of the lifting cylinders, the ladles at both ends are at different heights, causing the ladle filled with molten steel to be suspended. The lapels need to be raised or lowered by adjusting the regulator to extend or shorten the adjustment device to achieve a balanced state, which greatly increases safety risks.

[0039] In some embodiments, the lifting bracket 23 includes a first bracket 231, a first upper slider 232, a first lower slider 233, a second bracket 234, a second upper slider 235 and a second lower slider 236, one end of the first upper slider 232 is rotatably connected to the first bracket 231, and the other end of the first upper slider 232 is slidably connected to the second track frame 22; one end of the first lower slider 233 is rotatably connected to the first bracket 231, and the other end of the first lower slider 233 is slidably connected to the first track frame 21; the second bracket 234 is rotatably connected to the first bracket 231; one end of the second upper slider 235 is rotatably connected to the second bracket 234, and the other end of the second upper slider 235 is slidably connected to the second track frame 22; one end of the second lower slider 236 is rotatably connected to the second bracket 234, and the other end of the second lower slider 236 is slidably connected to the second track frame 22.

Therefore, when the end of the first bracket 231 moves toward the end of the second bracket 234, it can drive the second track frame 22 to move away from the first track frame 21; when the end of the first bracket 231 moves away from the end of the second bracket 234, it can drive the second track frame 22 to move toward the first track frame 21. A first upper slider 232 and a first lower slider 233 are respectively connected to the ends of the first bracket 231. One end of the first upper slider 232 is rotatably connected to the first bracket 231, and the other end of the first upper slider 232 is slidably connected to the second track frame 22. One end of the first lower slider 233 is rotatably connected to the first bracket 231, and the other end of the first lower slider 233 is slidably connected to the first track frame 21. One end of the second upper slider 235 is rotatably connected to the second bracket 234, and the other end of the second upper slider 235 is slidably connected to the second track frame 22. One end of the second lower slider 236 is rotatably connected to the second bracket 234, and the other end of the second lower slider 236 is slidably connected to the second track frame 22. In this way, the first track frame 21 and the second track frame 22 are connected using the lifting bracket 23.

[0041] In some embodiments, a middle support 211 is provided in the middle of the first track frame 21 , and end supports 212 are provided at both ends of the first track frame 21 .

[0042] In some embodiments, the lifting member 2 also includes a driving screw 24, one end of which is rotatably connected to the middle support 211, the other end of which is rotatably connected to the end support 212, and the middle part of the driving screw 24 is threadedly connected to the second upper slider 235.

[0043] In some embodiments, a driving member 25 is also included, and the driving member 25 includes a screw gear 251, a motor gear 252, a reduction motor 253 and a rotating motor 254.

[0044] In this embodiment, one end of the drive screw 24 is rotatably connected to the middle support 211, and the other end of the drive screw 24 is rotatably connected to the end support 212. Furthermore, the middle portion of the drive screw 24 is threadedly connected to the second upper slider 235. Thus, when the drive screw 24 rotates, the second upper slider 235 can reciprocate on the drive screw 24. A screw gear 251 is connected to the end of the drive screw 24 near the end support 212. A motor gear 252 meshes with the screw gear 251. A reduction motor 253 includes a fixed end, a rotation input end, and a rotation output end. The fixed end of the reduction motor 253 is fixedly connected to the first track frame 21, and the rotation output end of the reduction motor 253 is connected to the motor gear 252. A rotating motor 254 includes a fixed end and a rotating end. The fixed end of the rotating motor 254 is fixedly connected to the first track frame 21, and the rotating end of the rotating motor 254 is connected to the rotation output end of the reduction motor 253. Therefore, the rotating motor 254 rotates to drive the reduction motor 253 to rotate. After the reduction motor 253 increases the torque, it drives the motor gear 252 to rotate. The motor gear 252 drives the screw gear 251 to rotate, thereby realizing the rotation of the screw gear 251.

[0045] In some embodiments, the lifting member 2 also includes a locking screw 26 and a locking gear 27, one end of the locking screw 26 is rotatably connected to the middle support 211, the other end of the locking screw 26 is rotatably connected to the end support 212, and the middle part of the locking screw 26 is threadedly connected to the first lower slider 233; the locking gear 27 is connected to one end of the locking screw 26 close to the end support 212.

[0046] In some embodiments, a locking member 28 is further included, and the locking member 28 includes a locking guide rail seat 281 and a locking tooth 282. There are two locking guide rail seats 281, and the two locking guide rail seats 281 are both connected to the first track frame 21 and are symmetrically arranged on both sides of the locking gear 27; the locking tooth 282 is slidingly connected to the locking guide rail seat 281, and the locking tooth 282 is located below the locking gear 27, and when the locking tooth 282 moves to a position engaged with the locking gear 27, the locking tooth 282 locks the locking gear 27.

[0047] In some embodiments, the locking member 28 also includes a latching tooth screw 283 and a latching tooth motor 284. There are two latching tooth screws 283, and the two latching tooth screws 283 are respectively rotatably connected to the two locking guide rail seats 281, and the middle parts of the two latching tooth screws 283 are respectively threadedly connected to the locking latch 282; the latching tooth motor 284 is provided with a fixed end and a rotating end. The fixed end of the latching tooth motor 284 is fixedly connected to the locking guide rail seat 281, and the rotating end of the latching tooth motor 284 is connected to the latching tooth screw 283.

[0048] In this embodiment, when it is necessary to stop the lifting, the second track frame 22 is first stopped, and the latch motor 284 is turned on. The latch motor 284 drives the latch screw 283 on this side to rotate, and the latch screw 283 drives the locking latch 282 to move up and down on the locking guide rail seat 281, thereby driving the locking latch 282 to lock the locking gear 27. As a result, the locking screw 26 stops rotating, and the second track frame 22 is completely locked.

[0049] In some embodiments, the base 1 includes a lower frame 11, an upper frame 12, an upper frame rotating gear 13, a base motor 14, a position sensor 5 and a sensor sensing end 6, the upper frame 12 is rotatably connected to the lower frame 11, and an upper frame tooth 121 is provided in the upper frame 12; the upper frame rotating gear 13 is engaged with the upper frame tooth 121; the base motor 14 is provided with a fixed end and a rotating end, the fixed end of the base motor 14 is fixedly connected to the lower frame 11, and the rotating end of the base motor 14 is connected to the upper frame rotating gear 13; the position sensor 5 is connected to the lower frame 11; the sensor sensing end 6 is connected to the upper frame 12, and the sensing signal emitted by the position sensor 5 is within the motion trajectory range of the position sensor sensing end 6.

[0050] In this embodiment, since the ladle turret is in operation, high-temperature steel solution will be loaded in the ladle. In order to increase the safety of the operator's operation, the position sensor 5 and the sensor sensing end 6 are used to detect the position of the second track frame 22 relative to the first track frame 21 in real time. In this solution, there are three position sensors 5, which are respectively set at 0°, 90° and 180° positions. It is convenient for the operator to observe the relevant information of the rotation of the second track frame 22 at the control end. For example: when the second track frame 22 rotates from the starting position, the sensor sensing end 6 contacts the three position sensors 5 at 0°, 90° and 180° positions respectively, so that the operator can accurately monitor the rotation process of the second track frame 22. Vice versa, it will not be repeated here.

[0051] In some embodiments, a rotating arm 3 is further included. Two rotating arms 3 are provided. The two rotating arms 3 are respectively connected to the two ends of the second track frame 22 , and the rotating arms 3 are fixedly connected to the ladle 4 .

[0052] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0053] When the two ends of the bottom of the lifting bracket move away from each other, the second track frame moves toward the first track frame; when the two ends of the bottom of the lifting bracket move toward each other, the second track frame moves away from the first track frame. This ensures that the lifting and lowering of the two ladles are always synchronized, improving operational safety. This solves the problem of existing ladles that, when the lifting cylinders are out of sync or malfunction, cause the ladles at both ends to be at different heights, leaving the ladle filled with molten steel in a suspended state. The ladles need to be raised or lowered by adjusting the regulator to extend or shorten the adjustment device to achieve a balanced state, which greatly increases safety risks.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
