[0025] Embodiment:

[0026] As Figures 1-7 shown, a ladle combination moving device of a teeming trolley, comprising a travelling crane frame 1, the travelling crane frame 1 is equipped with a transverse moving trolley 2 and a hydraulic device 21 for driving the transverse moving trolley 2 to move laterally on the travelling crane frame 1, the transverse moving trolley 2 is equipped with a bearing frame 3 and a lifting device 4 for driving the bearing frame 3 to move up and down, the travelling crane frame 1 is equipped with a sliding groove for the movement of a ladle 6, and the transverse moving trolley 2 and the bearing frame 3 are both equipped with a ladle groove 35 for placing the ladle 6.

[0027] The ladle 6 is placed on the ladle slot 35 of the supporting frame 3. The sprue 61 of the ladle 6 passes through the ladle slot 35 of the traversing trolley 2 and the sliding groove of the traveling frame 1. The supporting frame 3 is raised and lowered by the lifting device 4, thereby moving the ladle 6 up and down. The height of the sprue 61 of the ladle 6 and the top of the pouring pipe can be adjusted according to the height of the pouring pipe, so that the pouring port and the sprue 61 of the ladle 6 are close together. This prevents the molten steel from being exposed to air for a long time during pouring and also prevents the danger of splashing during pouring. The traversing trolley 2 is moved laterally on the traveling frame 1 by the hydraulic device 21, which moves the ladle 6 laterally, thereby flexibly adjusting the position of the ladle 6 so that the sprue 61 of the ladle 6 corresponds to the mold opening of different shaped casting models, making it widely adaptable. The hydraulic device 21 can be a hydraulic cylinder. The output shaft of the hydraulic cylinder is connected to the traversing trolley 2.

[0028] The lifting device 4 includes a drive motor 41, a transmission shaft 42 on the output shaft of the drive motor 41, a reducer 43 on the transmission shaft 42, a worm gear screw jack 44 on the output shaft of the reducer 43, a nut 31 on the bearing frame 3, and the screw 45 of the worm gear screw jack 44 threaded through the nut 31.

[0029] The drive motor 41 drives the transmission shaft 42 to rotate horizontally. The transmission shaft 42 drives the reducer 43, which in turn drives the worm gear screw jack 44, converting the horizontal rotation into vertical rotation. This causes the vertical screw 45 to rotate, and the screw 45, connected to the nut 31 by a thread, drives the load-bearing frame 3 to move vertically. The reducer 43 can be a cycloidal pinwheel reducer.

[0030] Two drive motors 41 and two drive shafts 42 are used, located on both sides of the load-bearing frame 3. Four reducers 43 and four worm gear screw jacks 44 are used, located at the four corners of the load-bearing frame 3. Using four worm gear screw jacks 44 prevents rotation of the load-bearing frame 3 during lifting and lowering, while improving the stability of the load-bearing frame 3 during lifting and lowering. The four nuts 31 of the load-bearing frame 3 are on the same horizontal plane, ensuring even load distribution at the four stress points and consistent vertical lifting and lowering.

[0031] Upper and lower limit sensors can be installed on the support frame 3, and a lateral limit sensor can be installed on the lateral trolley 2 to monitor the lifting and lateral movement of the ladle.

[0032] The first stop block 32 and the second stop block 33 are arranged on the bearing frame 3 in sequence along the direction of the ladle 6, and the height of the second stop block 33 is higher than that of the first stop block 32.

[0033] The weighing device 34 is arranged between the first stop block 32 and the second stop block 33 on the bearing frame 3.

[0034] The bottom of the transverse moving trolley 2 is provided with a roller 22, and the crane frame 1 is provided with a sliding rail 11 for the roller 22 to roll.

[0035] The hydraulic device 21 is adopted in two, and the two hydraulic devices 21 are connected with the two sides of the transverse moving trolley 2 respectively.

[0036] The synchronous device 5 comprises a synchronous shaft 52 which is rotatably connected to the crane frame 1 through a bearing seat 51, and the two ends of the synchronous shaft 52 are symmetrically provided with first connecting rods 53, the other ends of the first connecting rods 53 are hingedly connected with second connecting rods 54, and the other ends of the second connecting rods 54 are connected with the transverse moving trolley 2 through a support shaft 55.

[0037] The part not described in the utility model is the prior art, and therefore will not be specifically described here.
