Embodiment Construction
[0010] Such as figure 1 As shown, the sub-basket alignment device for pouring large ladles of the present invention includes a counterweight base 1, on which a rotating shaft 4 extending vertically upwards is rotatably connected, and a large gear 3 is fixed on the rotating shaft 4. The counterweight base 1 is provided with a deceleration motor 12, the output shaft of the deceleration motor 12 is connected with a pinion 11 meshing with the large gear 3, the upper end of the rotating shaft 4 is equipped with a reel 5, and a wire rope 8 is wound on the reel 5 , the free end of the steel wire rope 8 is provided with a hook, and the outer circumference of the ladle 9 to be aligned is provided with a shackle 6; The driving shaft 4 drives the reel to tighten the wire rope 8 so that the ladle 9 rotates to a predetermined position to achieve alignment with the sprue cup. The geared motor 12 has the functions of forward rotation, reverse rotation and brake, and is connected to the power...

The invention relates to the technical field of auxiliary tools of large steel casting pouring operation, in particular to a ladle rotating and aligning device for large ladle pouring. The device comprises a balance weight base; the balance weight base is connected to a rotating shaft extending out vertically and upwards in a rotating mode, and a big gear is fixed to the rotating shaft; a speed reduction motor is arranged on the balance weight base, and an output shaft of the speed reduction motor is connected to a pinion meshing with the big gear; a winding reel is installed at the upper end of the rotating shaft, a steel wire rope winds around the winding reel, a hook is arranged at the free end of the steel wire rope, and a hook ring is correspondingly arranged on the periphery of a ladle to be aligned; and in the process of rotating and aligning the ladle, the steel wire rope winds around the periphery of the ladle by 1 / 2-1 circle, the hook hooks the hook ring, the speed reduction motor drives the rotating shaft to drive the winding reel to tighten the steel wire rope so that the ladle can be rotated to the preset position and aligned to a sprue cup, and the speed reduction motor has the forward rotation function, the reverse rotation function and the brake contracting function. According to the device, the ladle can be fast and accurately aligned before pouring, the alignment efficiency can be improved, and the work labor intensity can be lowered.
Description
technical field [0001] The invention relates to the technical field of auxiliary tool equipment for pouring large-scale steel castings, in particular to a sub-ladle alignment device for large-scale ladle pouring, which is used for aligning the sliding nozzle under the ladle and the sprue cup on the sand mold before pouring allow. Background technique [0002] At present, when pouring large-scale steel castings, the ladle full of molten steel is hoisted to the top of the casting sand mold by a double-girder bridge crane, and then the position of the ladle is roughly adjusted by the double-girder bridge crane to make the sliding nozzle under the ladle reach the gate. cup above. At this time, due to the angular deviation between the sliding nozzle below the ladle and the center of the sprue cup on the sand gate, it is necessary to rotate the ladle to make the sliding nozzle below the ladle align accurately with the center of the pouring cup. The current subcontracting measure...
