[0002] In the production of molten iron casting, the ladle filled with molten iron needs to be turned over so that the molten iron can be accurately poured into the casting mold. The traditional way of turning the ladle usually adopts manual operation or simple mechanical devices, which has problems such as difficult operation, low safety and low efficiency.

[0003] At present, the existing molten iron casting is usually carried out by hoisting the ladle and then turning it over for casting. This ladle turning method, due to the lack of support and fixation for the ladle, cannot accurately locate the pouring point of the ladle during the turning process, resulting in molten iron splashing and scalding workers. In addition, this ladle turning method is easy to unhook, causing the ladle to fall, causing damage to surrounding machinery and labor.

[0047] The second driving member 7 is installed at the front position of the upper surface of the bag turning assembly 2. The second driving member 7 can drive the clamping assembly 5 and the covering assembly 6 to work.

[0048] In this embodiment, the ladle 4 can be supported and prevented by the ladle turning component 2, and the ladle turning component 2 can be driven to turn over by the first driving member 3, so that the molten iron in the ladle 4 is poured out for pouring, and the accurate pouring of the molten iron ladle is realized, and an anti-reversal structure 8 is installed on the first driving member 3, which can prevent the first driving member 3 from reversing when the ladle turning component 2 is driven to rotate, causing the molten iron ladle 4 on the ladle turning component 2 to shake and the molten iron to splash, and the ladle 4 can be clamped and fixed by the clamping component 5, so that the molten iron ladle 4 is stably placed on the ladle turning component 2, avoiding the ladle 4 from slipping when the ladle turning component 2 is turned over, and the ladle 4 can be stably placed on the ladle turning component 2 by the clamping component 5. Component 6 can cover the opening at the upper end of the molten iron ladle 4. On the one hand, it can effectively block the splashing molten iron and reduce the risk of harm to surrounding personnel and equipment caused by the molten iron. On the other hand, the cover can block part of the heat radiation, protect the operator from high temperature damage, reduce the temperature of the working environment, and improve the safety and comfort of operation. At the same time, it can also reduce the contact area and time between the molten iron and the air, reduce the degree of oxidation of the molten iron, improve the quality of the casting, and reduce the heat loss of the molten iron. Reduce energy consumption, keep the temperature of the molten iron stable during the pouring process, which helps to improve the efficiency of casting production and reduce energy waste.

[0049] The clamping and covering of the ladle 4 are carried out synchronously under the coordinated action of the second driving member 7, and the two work closely together. This design can greatly save working time, avoid the waste of resources caused by separate driving, effectively save the use of driving components, and improve the overall working efficiency.

[0050] See also Figure 3-4 The bag turning assembly 2 includes a support beam 21, a rotating beam 22 and a support plate 23. There are two support beams 21, which are symmetrically installed on the right end of the upper surface of the operating frame 1. The upper ends of the two support beams 21 are rotatably installed with the rotating beams 22, and the lower ends of the two rotating beams 22 are jointly installed with the support plate 23. A rectangular opening is opened in the center of the operating frame 1, and a gear plate 24 is fixedly connected to the lower surface of the support plate 23. The lower end of the gear plate 24 passes through the rectangular opening and can extend to the lower side of the operating frame 1.

[0051] The first driving member 3 includes a first supporting frame 31, a driving gear 32 and a first motor 33. The first supporting frame 31 is fixedly mounted on the left end of the upper surface of the operating frame 1. The driving gear 32 is rotatably mounted on the upper end of the first supporting frame 31. The first motor 33 is fixedly mounted on the rear side of the upper end of the first supporting frame 31. The output shaft of the first motor 33 is connected with the driving gear 32, and the driving gear 32 is meshingly connected with the gear plate 24. When in use, the driving gear 32 is driven to rotate by the first motor 33. Under the meshing action of the driving gear 32 and the gear plate 24, the gear plate 24 can rotate, so that the ladle turning assembly 2 drives the molten iron ladle 4 to turn over and dump, and during the turning process, the inclination angle of the molten iron ladle 4 is controlled by the meshing drive between the gears, so that the inclination angle of the molten iron ladle 4 can be more accurately controlled when the molten iron is dumped.

[0052] See also Figure 2 , Figure 5 , Figure 6 and Figure 7In order to prevent the first motor 33 from malfunctioning during the molten iron pouring process, which may cause the bag turning assembly 2 to reverse, an anti-reversal structure 8 is provided on the first support frame 31. Specifically, the anti-reversal structure 8 includes a ratchet disc 81, a limit block 82, a limit rod 83 and an L-shaped plate 84. The ratchet disc 81 is fixedly mounted on the front upper end of the first support frame 31, and the ratchet disc 81 is coaxially connected to the driving gear 32. The limit block 82 is fixedly mounted on the front side of the first support frame 31. The limit block 82 is located at the lower side of the ratchet disc 81, and a limit rod 83 is provided on the limit block 82. The through hole 821 is set obliquely, and the limit rod 83 is installed in the through hole 821 on the limit block 82. The lower side of the limit block 82 is also installed with an L-shaped plate 84, and the vertical side wall of the L-shaped plate 84 is fixedly installed with a first rectangular plate 841. The left side wall of the limit rod 83 is installed with a second rectangular plate 836. A spring 842 is connected between the first rectangular plate 841 and the second rectangular plate 836. The lower end of the limit rod 83 is installed with a hinge support 831, and a positioning rod 832 is rotatably installed on the hinge support 831. The lower end of the positioning rod 832 is fixed A positioning plate 833 is connected, and a buckle 834 is fixedly connected to the lower surface of the positioning plate 833. A positioning notch 843 is provided at the end of the horizontal side wall of the L-shaped plate 84. When the first driving member 3 is used to normally drive the bag turning assembly 2 to rotate, the ratchet plate 81 rotates along with the driving gear 32. The direction of rotation of the ratchet plate 81 is opposite to the direction of the ratchet teeth. Therefore, the ratchet teeth can push the limiting rod 83 downward, so that the ratchet plate 81 can rotate normally, and under the action of the spring 842, the limiting rod 83 can be extended upward in time when it is downward. , so that the ratchet disk 81 can be limited at any time. When the first motor 33 fails, the bag turning assembly 2 will reverse under the action of gravity. At this time, the driving gear 32 drives the ratchet disk 81 to rotate in the opposite direction. At this time, the rotation direction of the ratchet disk 81 is the same as the direction of the ratchet teeth, and the tip of the ratchet teeth will abut against the limiting rod 83. Under the action of the limiting rod 83, the ratchet disk 81 cannot rotate, thereby keeping the driving gear 32 and the bag turning assembly 2 stable, avoiding the bag turning assembly 2 from rotating downward quickly when the first motor 33 fails, causing the molten iron in the molten iron ladle 4 to splash out.

[0053] When the molten iron in the ladle 4 is poured out, it is necessary to rotate it to a vertical state. At this time, pull the pull buckle 834 to move the limit rod 83 downward, and then drop the positioning rod 832 into the positioning notch 843. Under the action of the positioning plate 833 and the spring 842, the positioning rod 832 can be stably stuck on the L-shaped plate 84. At this time, the upper end of the limit rod 83 does not contact the ratchet disk 81, and the ratchet disk 81 can rotate in the opposite direction. At this time, the first driving member 3 can be used to rotate the bag turning assembly 2 to its original position.

[0054] See also Figure 1 , Figure 2 and Figure 8The clamping assembly 5 includes a circular sleeve 51 and a clamping arm 52. The circular sleeve 51 is movably mounted on the support plate 23. A circular rack 53 is fixedly mounted on the lower part of the front side of the circular sleeve 51. Universal wheels 54 are evenly mounted on the bottom of the circular sleeve 51. The universal wheels 54 can support the circular sleeve 51 and will not affect the normal rotation of the circular sleeve 51. Installation notches are evenly opened on the side walls of the circular sleeve 51. The clamping arm 52 is rotatably mounted in the installation notch on the circular sleeve 51, and one end of the clamping arm 52 is rotatably mounted on the support plate 23.

[0055] The clamping arm 52 includes a strip-shaped movable clamping plate 521, a rectangular frame 522, a rotating roller 523 and a support rod 524. The rectangular frame 522 is rotatably installed in the installation notch on the circular sleeve 51. The strip-shaped movable clamping plate 521 is movably penetrated in the rectangular frame 522. The rotating roller 523 is rotatably installed at one end of the strip-shaped movable clamping plate 521. The support rod 524 is rotatably installed at the other end of the strip-shaped movable clamping plate 521. The lower end of the support rod 524 is fixedly installed on the support plate 23. When the ladle 4 is placed on the support plate 23, the annular rack 53 on the circular sleeve 51 can be driven to rotate by the second driving member 7. At this time, the circular sleeve 51 can rotate on its own. During the rotation of the circular sleeve 51, the rectangular frame 522 can be driven to change its position. Since one end of the strip movable splint 521 is fixed, when the position of the rectangular frame 522 changes, it will drive the strip movable splint 521 to rotate around the support rod 524. At this time, the end of the strip movable splint 521 can approach the molten iron ladle 4 in the circular sleeve 51. When the end of the strip movable splint 521 is tightly pressed against the molten iron ladle 4, the molten iron ladle 4 can be fixed in the circular sleeve 51, preventing the molten iron ladle 4 from moving on the ladle turning component 2 during the ladle turning process, causing the molten iron in the ladle 4 to splash out.

[0056] The covering assembly 6 includes a second support frame 61, a rotating rod 62, an L-shaped rod 63 and a shielding cover 64. The second support frame 61 is fixedly installed on the left end of the upper surface of the support plate 23. The rotating rod 62 is rotatably installed on the second support frame 61. The two ends of the rotating rod 62 are respectively fixedly connected with the L-shaped rod 63, and the ends of the two L-shaped rods 63 are commonly connected with the shielding cover 64.

[0057] See also Figure 8-10 The second driving member 7 includes a vertical plate 71, a second motor 72 and a worm 73. The two ends of the worm 73 are respectively installed with vertical plates 71, and the vertical plate 71 is fixedly installed on the support plate 23. The second motor 72 is fixedly installed on the right vertical plate 71. The output shaft of the second motor 72 is connected to the worm 73, and the worm 73 is meshed with the annular rack 53. When in use, the worm 73 can be driven to rotate by the second motor 72. During the rotation of the worm 73, the annular rack 53 can be driven to rotate, so that the clamping assembly 5 clamps the molten iron ladle 4.

[0058] The second driving member 7 also includes a rotating short shaft 75, a first bevel gear 74, a second bevel gear 76, a first pulley 77, a second pulley 78 and a transmission belt 79. The first bevel gear 74 is fixedly mounted on the left end of the worm 73, the rotating short shaft 75 is rotatably mounted on the front end side wall of the second support frame 61, the end of the rotating short shaft 75 is fixedly mounted with a second bevel gear 76, the second bevel gear 76 is meshed with the first bevel gear 74, the rotating short shaft 75 is fixedly mounted with a first pulley 77, the second pulley 78 is fixedly mounted It is fixedly installed at the front end of the rotating rod 62, and a transmission belt 79 is installed between the first pulley 77 and the second pulley 78. When the worm 73 rotates, the rotating short shaft 75 can be rotated at the same time through the meshing connection of the first bevel gear 74 and the second bevel gear 76. Under the action of the first pulley 77, the second pulley 78 and the transmission belt 79, the rotating rod 62 can be driven to rotate at the same time. At this time, the rotating rod 62 drives the L-shaped rod 63 to rotate, so that the shielding cover 64 can cover the molten iron ladle 4.

[0059] Specifically, the working principle of the lifting ladle turner for molten iron casting is as follows: when in use, first use a tool to place the molten iron ladle 4 on the support plate 23, and then turn on the second motor 72, so that the second motor 72 drives the worm 73 to rotate, and the worm 73 can drive the annular rack 53 to rotate during the rotation process, and then the circular sleeve 51 can rotate on its own, and during the rotation process of the circular sleeve 51, it can drive the rectangular frame 522 to change its position. Since one end of the strip movable splint 521 is fixed, when the position of the rectangular frame 522 changes, it will drive the strip movable splint 521 to rotate around the support rod 524, and at this time, the end of the strip movable splint 521 The end can be close to the molten iron ladle 4 in the circular sleeve 51. When the end of the strip movable splint 521 is tightly against the molten iron ladle 4, the molten iron ladle 4 can be fixed in the circular sleeve 51. At the same time, under the meshing connection of the first bevel gear 74 and the second bevel gear 76, the rotating short shaft 75 can also rotate at the same time. Under the action of the first pulley 77, the second pulley 78 and the transmission belt 79, the rotating rod 62 can also be driven to rotate at the same time. At this time, the rotating rod 62 drives the L-shaped rod 63 to rotate, so that the shielding cover 64 can cover the molten iron ladle 4. At this time, the molten iron ladle 4 can be fixed on the ladle turning assembly 2 and the opening at the upper end of the molten iron ladle 4 can be shielded.

[0060] Then, the first motor 33 is turned on, and the driving gear 32 is driven to rotate by the first motor 33. Under the meshing action of the driving gear 32 and the gear plate 24, the gear plate 24 can be rotated, so that the ladle turning assembly 2 drives the molten iron ladle 4 to turn over and dump, and in the turning process, the inclination angle of the molten iron ladle 4 is controlled by the meshing drive between the gears. When the molten iron is dumped, the inclination angle of the molten iron ladle 4 can be controlled more accurately. During the entire dumping process of the molten iron ladle 4, the anti-reversal structure 8 can limit the first driving member 3 to prevent the first driving member 3 from rotating in the opposite direction. Specifically, when the first driving member 3 is used to normally drive the ladle turning assembly 2 to rotate, the ratchet plate 81 rotates together with the driving gear 32, and the rotation direction of the ratchet plate 81 is the same as the direction of the ratchet tooth. On the contrary, the ratchet can push the limit rod 83 downward, so that the ratchet disk 81 can rotate normally, and under the action of the spring 842, the limit rod 83 can be extended upward in time when it is downward, so as to limit the ratchet disk 81 at any time. When the first motor 33 fails, under the action of gravity, the bag turning assembly 2 will reverse. At this time, the driving gear 32 drives the ratchet disk 81 to rotate in the opposite direction. At this time, the rotation direction of the ratchet disk 81 is the same as the direction of the ratchet, and the tip of the ratchet will rest on the limit rod 83. Under the action of the limit rod 83, the ratchet disk 81 cannot rotate, thereby making the driving gear 32 and the bag turning assembly 2 remain stable, avoiding the bag turning assembly 2 from rotating downward quickly when the first motor 33 fails, causing the molten iron in the molten iron ladle 4 to splash out.

[0061] It should be noted that the specific model specifications of the first motor 33 and the second motor 72 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be repeated in detail.

[0062] The power supply and principle of the first motor 33 and the second motor 72 are clear to those skilled in the art and will not be described in detail herein.
