One end of the first elastic member 39 is fixedly connected to the first guide frame 37, and the other end is fixedly connected to the top block 38. The first elastic member 39 is used to push the top block 38 to insert into the connecting groove 35 from the through hole 36, and an adjusting rod 310 is fixedly installed on the top block 38.

[0023] A second guide frame 311 is fixedly installed on the ladle 31, and a second elastic member 312 for pushing up the limiting assembly 4 is mounted on the guide rod of the second guide frame 311.

After the limiting block 41 is inserted into the limiting hole 34, the plug rod 33 is in a state of blocking the pouring port of the ladle 31. One end of the second elastic member 312 is fixedly connected to the second guide frame 311, and the other end is fixedly connected to the limiting block 41. The second elastic member 312 is used to push the limiting block 41 to stably insert it into the limiting hole 34, reduce the risk of the limiting block 41 being separated, and improve the stability of the pouring port blocking. The pushing block 42 is slidably connected to the lifting block 32 through the guide rail 43.

When the push block 42 rises, the inclined top surface 46 gradually disengages from the adjusting rod 310, so that the top block 38 is inserted into the connecting groove 35 again under the action of the first elastic member 39. The elastic force of the second elastic member 312 is greater than that of the first elastic member 39, ensuring that the limit block 41 can be stably self-locked in the limit hole 34; one end of the limit block 41 is provided with a plug-in groove 47, and two groups of arc blocks 48 are fixedly installed in the plug-in groove 47.

[0025] Reference Figure 1 , Figure 4 , Fig. 9 and Fig.10 A moving assembly 5 is installed on the trolley 1, and the moving assembly 5 includes a beam frame 51 fixedly installed on the trolley 1, a first telescopic cylinder 52 is fixedly installed on the beam frame 51, an output shaft of the first telescopic cylinder 52 is fixedly connected to a moving frame 53 slidably connected to the beam frame 51, a guide hole 54 is opened on the moving frame 53, and a second dial head 55 is fixedly installed in the guide hole 54; a pushing assembly 6 and a lifting assembly 7 are installed on the moving frame 53.

[0026] The ejection assembly 6 includes a second telescopic cylinder 61 fixedly mounted on the mobile frame 53, a connecting seat 62 fixedly mounted on the output end of the second telescopic cylinder 61, a push rod 63 rotatably connected to the connecting seat 62, used to assist the ejection limit block 41 to disengage from the limit hole 34, the push rod 63 passes through the guide hole 54, a second track groove 64 is opened on the push rod 63, the second track groove 64 includes two horizontal grooves arranged parallel to the axis of the push rod 63 and an arc groove connecting the two horizontal grooves, the two horizontal grooves have a certain deflection angle, the second dial head 55 is inserted in the horizontal groove or the arc groove for movement, and a buckle plate 65 is fixedly mounted on the end of the push rod 63, the buckle plate 65 Insert it into the plug-in slot 47 from the gap between the two groups of arc blocks 48. When the pinch plate 65 moves to the rear side of the arc block 48, the second dial head 55 moves from the horizontal slot to the arc slot, and then moves to another horizontal slot. At this time, the push rod 63 drives the pinch plate 65 to rotate, so that the pinch plate 65 and the arc block 48 are misaligned and overlapped in the axial direction. When the push rod 63 returns, it can effectively assist the limit block 41 to be stably inserted into the limit hole 34; the diameter of the push rod 63 is smaller than the width and height of the limit block 41, thereby ensuring that after the push rod 63 is inserted into the limit hole 34, it does not contact the lifting block 32 during the lifting process of the lifting block 32, so that the lifting block 32 can operate stably.

[0027] The lifting assembly 7 includes a third telescopic cylinder 71 fixedly mounted on the moving frame 53, the output shaft of the third telescopic cylinder 71 is fixedly mounted with a lifting plate 72 slidably connected to the moving frame 53, a connecting rod 73 is fixedly mounted at the bottom of the lifting plate 72, a buckle groove 74 is provided on the connecting rod 73, the connecting rod 73 is inserted into the connecting groove 35 and contacts with the bottom of the connecting groove 35, at this time the buckle groove 74 is connected with the through hole 36, the top block 38 is inserted into the through hole 36 and the buckle groove 74, the connecting rod 73 is automatically locked on the lifting block 32, so as to realize the power connection between the output end of the lifting assembly 7 and the lifting block 32.

[0028] Working principle: The pouring assembly 3 is controlled by a lifting vehicle or a crane and plugged into the support frame 22. The electric rotating table 21 drives the pouring assembly 3 to rotate to the pouring position. The output shaft of the first telescopic cylinder 52 drives the moving frame 53 to move, so that the connecting rod 73 is directly above the connecting groove 35 and is coaxial. At this time, the top rod 63 is coaxial with the plug-in groove 47.

[0029] The output shaft of the third telescopic cylinder 71 drives the lifting plate 72 and the connecting rod 73 to descend, and the connecting rod 73 is inserted into the connecting groove 35 and contacts the bottom of the connecting groove 35. At this time, the buckle groove 74 is connected with the through hole 36. A pressure sensor can be provided at the bottom of the connecting rod 73 to monitor the blocking pressure of the plug rod 33.

[0030] The output shaft of the second telescopic cylinder 61 pushes the push rod 63 to move, and the push rod 63 drives the buckle plate 65 to insert into the plug-in groove 47 from the gap between the two groups of arc blocks 48. When the buckle plate 65 moves to the rear side of the arc block 48, the second dial head 55 moves from the horizontal groove to the arc groove, and then moves to another horizontal groove. At this time, the push rod 63 drives the buckle plate 65 to rotate, so that the buckle plate 65 and the arc block 48 are misaligned and overlapped in the axial direction. The push rod 63 continues to move and pushes the limit block 41 out of the limit hole 34. The limit block 41 compresses the second elastic member 312. In the process of the limit block 41 moving backward, the first dial head 45 is driven by the first track groove 44 to move the limit block 41 upward, and the inclined top surface 46 gradually disengages from the adjusting rod 310. Under the action of the first elastic member 39, the push block 38 moves and is inserted into the through hole 36 and the buckle groove 74 to limit the connecting rod 73. It should be noted that when the limiting block 41 is inserted into the limiting hole 34 , the top block 38 is in a state of being pushed out of the connecting groove 35 by the pushing block 42 .

[0031] The output shaft of the third telescopic cylinder 71 drives the connecting rod 73 to move up and down, and the connecting rod 73 drives the top block 38, the lifting block 32 and the plug rod 33 to move up and down, thereby controlling the pouring port at the bottom of the ladle 31 and adjusting the flow rate of the molten steel.

[0032] When the amount of molten steel in the ladle 31 is small or consumed, the output shaft of the second telescopic cylinder 61 drives the push rod 63 to return, and the limit block 41 is inserted into the limit hole 34 again under the action of the second elastic member 312 and the buckle plate 65, and the first dial head 45 drives the push block 42 to descend under the action of the first track groove 44, and the push block 42 pushes the adjusting rod 310 to make the push block 38 disengage from the buckle groove 74 and compress the first elastic member 39. After the push block 38 is disengaged from the connecting rod 73, the third telescopic cylinder 71 drives the connecting rod 73 to disengage from the lifting block 32; the second telescopic cylinder 61 drives the buckle plate 65 to disengage from the plug-in groove 47, and the first telescopic cylinder 52 drives the push assembly 6 and the lifting assembly 7 away from the ladle 31. After the ladle 31 newly filled with molten steel is plugged into the support frame 22, the electric rotating table 21 rotates to switch the positions of the two ladles 31, thereby realizing the rapid switching of the ladle 31, effectively reducing the problem of slow steel replenishment process of the ladle 31, and improving the pouring efficiency.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
