Description

Technical Field

[0001] This utility model relates to the technical field of molten iron transfer equipment, and in particular to a casting transfer car. Background Technology

[0002] In the production process of the foundry, a transfer car is needed to take the molten iron ladle from the molten iron transfer car in front of the electric furnace. After the slag in the molten iron is removed at the slag removal station, the molten iron ladle is transferred to the pouring transfer car in front of the pouring machine. The pouring transfer car lifts the molten iron ladle and pours the molten iron into the pouring ladle of the pouring machine.

[0003] The layout of main equipment in a foundry can vary. For example, the direction of the pouring machine may not be the same as that of the slag removal station. The molten iron ladle needs to be transferred from the electric furnace to a transfer car that matches the slag removal station for slag removal. Then, the molten iron ladle is transferred to the pouring transfer car in front of the pouring machine for pouring. The number of transfer cars is large, and the investment and maintenance costs of the equipment are high.

[0004] In addition, when the site environment is limited and the ground rail cannot be laid close to the casting machine, the molten iron in the casting ladle cannot be poured into the casting ladle. Additional equipment investment is required to modify the relevant structure of the casting ladle. This situation not only increases equipment investment but also affects the efficiency of operation. Utility Model Content

[0017] It includes a roller conveyor mounted on the traveling base, on which multiple rollers are rotatably mounted side by side, and a first motor is also mounted on the roller conveyor. The first motor is connected to the rollers in a driving connection, and the rolling direction of the rollers is consistent with the traveling direction of the traveling base.

[0018] The rotation of the rotating base relative to the translational base is also used to rotate the lifting frame above the docking platform.

[0019] The structure of the walking base is as follows:

[0020] The system includes a base frame on which multiple traveling wheels are rotatably mounted, and a connecting shaft that is driven to two of the traveling wheels. A second motor that is driven to the connecting shaft is also mounted on the base frame. The traveling wheels cooperate with a ground rail located in front of the casting machine.

[0021] The traveling base is equipped with a rack and a pair of rails. The rack is parallel to the rails, and the length direction of the rack is consistent with the moving direction of the translation base.

[0035] The beneficial effects of this utility model are as follows:

[0036] This utility model features a compact and reasonable structure and is easy to operate. By setting a translational base on the pouring and transfer car with a movement direction perpendicular to the walking base, the molten iron ladle on the lifting frame can be moved closer to or away from the pouring machine. A rotating base is set on the translational base, allowing the molten iron ladle on the lifting frame to rotate and face the slag removal equipment or the pouring machine. This enables the pouring and transfer car to meet the docking requirements of the slag removal station, allowing it to be used at the slag removal station, reducing the number of transfer cars in the foundry workshop, and lowering the investment and maintenance costs of the equipment. At the same time, when the ground rail cannot be laid close to the pouring machine, the molten iron ladle can be moved towards the pouring machine, ensuring that the molten iron in the ladle can be directly poured into the pouring machine, thus improving work efficiency in an economical and convenient way.

[0037] This utility model also has the following advantages:

[0039] A swing frame is hinged to the lifting frame. A ladle cover is set at one swing end of the swing frame, and a limiting end is set at the other swing end. A column that interacts with the swing frame on one side of the hinge is set on the rotating base, and a guide surface that interacts with the limiting end is set on the vertical frame. This enables the ladle cover to close and open during the lifting process of the lifting frame. The power of the vertical drive mechanism is used for the lifting of the lifting frame and simultaneously acts on the ladle cover. This enables the ladle cover to close automatically when the molten iron ladle is transferred with the casting transfer car, and to open automatically during the tilting of the molten iron ladle and the pouring of molten iron. This makes the casting transfer car multifunctional, ingeniously constructed, and with a simple and reliable transmission structure. Attached Figure Description

[0070] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0071] Example 1:

[0072] like Figures 1-8 As shown, the casting transfer vehicle of this embodiment includes: a traveling base 1, a translational base 2, a rotating base 3, a vertical frame 4, a lifting frame 5, and a rotary drive 6.

[0073] The traveling base 1 moves in a straight line, and the direction of travel of the traveling base 1 is consistent with the arrangement direction of the casting machine;

[0074] The translation base 2 is slidably mounted on the walking base 1. The sliding direction of the translation base 2 is perpendicular to the traveling direction of the walking base 1. The translation base 2 is provided with a translation drive mechanism 21 for driving the translation base 2 to move relative to the walking base 1.

[0075] The rotating base 3 is rotatably mounted on the translation base 2, and the rotating base 3 is provided with a rotation drive mechanism 31 for driving the rotating base 3 to rotate relative to the translation base 2;

[0076] A vertical frame 4 is fixedly installed on a rotating base 3, and a vertical drive mechanism 41 is installed on the vertical frame 4;

[0077] The lifting frame 5 is slidably mounted on the vertical frame 4 and is connected to the vertical drive mechanism 41. The vertical drive mechanism 41 is used to drive the lifting frame 5 to move up and down relative to the vertical frame 4. The lifting frame 5 is provided with brackets 51 that match the two side lugs of the molten iron ladle 9.

[0078] A rotary actuator 6, mounted on a bracket 51, is used to drive the molten iron ladle 9 to rotate;

[0079] The translation base 2 moves relative to the traveling base 1 to move the molten iron ladle 9 closer to or away from the casting machine, and the rotating base 3 rotates relative to the translation base 2 to face the molten iron ladle 9 toward the slag removal equipment or the casting machine.

[0080] Specifically, the walking base 1 travels along the ground rail in front of the casting machine; the bracket 51 is provided with a slot 510 that rotates with the shaft lug; the structure of the rotary drive 6 includes a mounting plate 61 fixedly installed on the bracket 51, a rotary drive 62 installed on the mounting plate 61, and a locking block 63 installed on the rotating end of the rotary drive 62, which is used to engage with the shaft lug.

[0081] Furthermore, such as Figures 2-3 As shown, the traveling base 1 is equipped with a docking platform 11 for placing the molten iron ladle 9. The structure of the docking platform 11 is as follows:

[0082] It includes a roller seat 1101 mounted on the traveling base 1, multiple rollers 1103 are rotatably mounted side by side on the roller seat 1101, and a first motor 1102 is also mounted on the roller seat 1101. The first motor 1102 is connected to the rollers 1103 in a transmission connection, and the rolling direction of the rollers 1103 is consistent with the traveling direction of the traveling base 1.

[0083] The rotation of the rotating base 3 relative to the translation base 2 is also used to rotate the lifting frame 5 above the docking platform 11.

[0084] The working process of the pouring and transport vehicle in this embodiment is as follows:

[0085] First, the docking platform 11 is used to receive the molten iron ladle 9 from the molten iron car in front of the electric furnace. When the traveling base 1 travels to the work position where it docks with the molten iron car in front of the electric furnace, the docking platform 11 starts to transport the molten iron ladle 9 between the two brackets 51. At the same time, the lug of the molten iron ladle 9 is located above the slot 510.

[0086] Then, the traveling base 1 moves and transports the molten iron ladle 9 to the front of the slag removal station. The rotary drive mechanism 31 drives the rotary base 3 to rotate the vertical frame 4, so that the molten iron ladle 9 faces the slag removal station. When the slag removal station is perpendicular to the direction of the casting machine, the rotation angle of the vertical frame 4 is 180 degrees. The vertical drive mechanism 41 is activated so that the shaft lug is located in the slot 510. After one shaft lug is engaged with the locking block 63, the rotary drive 6 drives the molten iron ladle 9 to rotate and tilt at a certain angle to perform the slag removal operation. During the process, the vertical drive mechanism 41 raises the height of the molten iron ladle 9 to match the height of the slag removal platform.

[0087] After the slag removal operation is completed, the traveling base 1 moves the molten iron ladle 9 to the front of the casting machine. The rotary drive mechanism 31 drives the rotary base 3 to rotate the vertical frame 4, so that the molten iron ladle 9 faces the casting machine. The vertical drive mechanism 41 lifts the molten iron ladle 9 to a suitable height. The translation drive mechanism 21 drives the translation base 2 to move the molten iron ladle 9 to a suitable position away from the casting machine. The rotary drive 6 drives the molten iron ladle 9 to rotate, pouring the molten iron in the molten iron ladle 9 into the casting ladle of the casting machine.

[0088] The action structure of the casting transfer car in this embodiment is multi-axis. The walking base 1 moves in the X-axis direction, the translation base 2 moves in the Y-axis direction, and the lifting frame 5 moves in the Z-axis direction. At the same time, the lifting frame 5 can rotate around the Z-axis. In addition, the rotary driver 6 drives the molten iron ladle 9 to rotate around the lug. The action mode of this casting transfer car is five axial actions.

[0089] By setting a translational base 2 on the pouring transfer car with a moving direction perpendicular to the moving direction of the traveling base 1, the molten iron ladle 9 on the lifting frame 5 can be moved closer to or away from the pouring machine. A rotating base 3 is set on the translational base 2, so that the molten iron ladle 9 on the lifting frame 5 can rotate to face the slag removal equipment or the pouring machine. This allows the pouring transfer car to also meet the docking requirements of the slag removal station, enabling the pouring transfer car to be used at the slag removal station, reducing the number of transfer cars in the foundry workshop, and lowering the investment and maintenance costs of the equipment. At the same time, when the ground rail cannot be laid close to the pouring machine, the molten iron ladle 9 can be moved towards the pouring machine to ensure that the molten iron in the ladle can be directly poured into the pouring ladle, thus improving the work efficiency in an economical and convenient way.

[0090] The pouring and transfer vehicle in this embodiment integrates multiple functions, making it easier to plan and layout the overall layout of the foundry.

[0091] Furthermore, such as Figures 2-3 As shown, the structure of the walking base 1 is as follows:

[0092] The system includes a base frame 12, on which multiple traveling wheels 15 are rotatably mounted. It also includes a connecting shaft 13, which is connected to two of the traveling wheels 15 via a transmission connection. A second motor 14, also connected to the connecting shaft 13, is mounted on the base frame 12. The traveling wheels 15 engage with a ground rail located in front of the casting machine. Specifically, there are four traveling wheels 15.

[0093] Furthermore, such as Figures 2-5 As shown, a rack 17 and a pair of rails 16 are provided on the walking base 1. The rack 17 is parallel to the rails 16. The length direction of the rack 17 is consistent with the moving direction of the translation base 2. The translation base 2 is provided with a number of guide wheels 22 that match the rails 16. Specifically, there are four guide wheels 22, which guide and support the translation base 2.

[0094] The structure of the translation drive mechanism 21 is as follows:

[0095] It includes a third motor 2101 fixedly installed on the translation base 2, and a first gear 2102 is installed at the output end of the third motor 2101. The first gear 2102 is connected to the rack 17 for transmission.

[0096] Specifically, extension plates 23 are installed on both sides of the lower part of the translation base 2, and multiple bearings 24 are installed on the extension plates 23. A limit plate 18 is provided on the base frame 12 below the track 16. The lower edge of the limit plate 18 is slidably connected to the bearings 24 to limit the vertical displacement of the translation base 2 and prevent the translation base 2 from overturning.

[0097] Furthermore, such as Figures 4-5 As shown, a rotary support 25 is installed on the translation base 2. The outer ring of the rotary support 25 is fixedly connected to the translation base 2, and the inner ring of the rotary support 25 is fixedly connected to the rotating base 3. The structure of the rotary drive mechanism 31 is as follows:

[0098] It includes a fourth motor 3101 mounted on the rotating base 3, and a second gear 3102 is mounted on the output end of the fourth motor 3101. The second gear 3102 is connected to the inner ring of the slewing support 25 for transmission.

[0099] Specifically, the slewing support 25 is an internal toothed slewing support; the rotation angle of the rotating base 3 can be detected by a sensor and the position signal is output to the control system of the casting and transfer vehicle for rotation angle control.

[0100] Furthermore, such as Figures 6-8 As shown, the structure of the vertical drive mechanism 41 is as follows:

[0101] The system includes a fifth motor 4101 mounted on the vertical frame 4, and a lead screw 4102 rotatably mounted on the vertical frame 4 at both ends. The lead screw 4102 is arranged in a vertical direction. The output end of the fifth motor 4101 is connected to the lead screw 4102 for transmission. A lifting block 4103 is mounted on the lead screw 4102. The center hole of the lifting block 4103 is engaged with the lead screw 4102. One side of the lifting block 4103 is fixedly connected to the lifting frame 5.

[0102] Specifically, one side of the lifting block 4103 is fixedly connected to the connecting block 52 in the middle of the back of the lifting frame 5. Rollers 53 are provided on both sides of the lifting frame 5. The rollers 53 are slidably connected to the guide grooves 42 provided on both sides of the vertical frame 4. The openings of the guide grooves 42 face the two sides of the lifting frame 5. The vertical position of the lifting frame 5 can be controlled by a distance sensor.

[0103] Example 2:

[0104] The fumes generated during the spheroidizing reaction of molten iron partially spill out, causing indoor environmental pollution. Nearby workers may come into contact with or inhale the dust, leading to physical discomfort and harm to their health. Based on Example 1, a lid 72 is installed on the molten iron ladle 9, which can be automatically opened and closed.

[0105] like Figures 7-12 As shown, it also includes a cover assembly 7, which includes a swing frame 71. The middle part of the swing frame 71 is a hinge part 70, which is hinged to the upper end of the lifting frame 5. A cover 72 is installed on the swing frame 71 on one side of the hinge part 70, and the end of the swing frame 71 on the other side of the hinge part 70 is a limiting end 73, including the cover 72 corresponding to the molten iron ladle 9.

[0106] The rotating base 3 is provided with an opening and closing structure for driving the swing frame 71 to swing around the hinge 70, which is used to open the ladle cover 72 or cover the molten iron ladle 9.

[0107] Specifically, there are two hinges 70, which are respectively hinged to both sides of the lifting frame 5; the swing frame 71 swings around the hinge 70, so that the cover 72 rises relative to the hinge 70 while the limiting end 73 falls relative to the hinge 70, or the limiting end 73 falls relative to the hinge 70 while the cover 72 falls relative to the hinge 70.

[0108] Furthermore, such as Figure 1 , Figures 4-5 , Figures 6-9 As shown, the structure of the opening and closing mechanism is as follows:

[0109] Includes a column 8 fixedly installed on a rotating base 3, the length of the column 8 is in the vertical direction, and the upper end of the column 8 is the drive end 801;

[0110] It also includes a drive surface 74 installed on a swing frame 71 between the cover 72 and the hinge 70, and the drive surface 74 is slidably engaged with the drive end 801.

[0111] A guide surface 43 is provided on the vertical frame 4, and the guide surface 43 slides in cooperation with the limiting end 73;

[0112] During the up-and-down movement of the lifting frame 5 relative to the vertical frame 4, the driving end 801 interacts with the swing frame 71 or the limiting end 73 interacts with the guide surface 43, causing the swing frame 71 to swing to open or close the cover 72.

[0113] Furthermore, such as Figure 5 As shown, the drive end 801 is a rolling wheel that is rotatably mounted on the upper end of the column 8.

[0114] Specifically, the lifting frame 5 is equipped with a guide sleeve 55 that slides with the column 8. The guide sleeve 55 guides the relative movement direction of the lifting frame 5 and the column 8 when the driving end 801 interacts with the driving surface 74, and also provides auxiliary force. The limiting end 73 is a rolling wheel that is rotatably installed at the end of the swing frame 71. The limiting end 73 slides with the guide surface 43. The guide surface 43 includes an inlet surface 4301 facing the hinge part 70. The inlet surface 4301 is an inclined surface. A vertical surface 4302 extends upward from the upper end of the inlet surface 4301. Ribs are provided outside the guide surface 43 to reinforce it. The connection between the vertical surface 4302 and the inlet surface 4301 is a curved transition.

[0115] Furthermore, such as Figure 9 As shown, a dust removal system 54 is installed on one side of the lifting frame 5, and the dust removal system 54 is connected to the smoke and dust channel of the cover 72.

[0116] Specifically, the dust duct of the cover 72 is connected to the inlet of the dust removal system 54 through a rigid pipe, including a first pipe 541 and a second pipe 542. The first pipe 541 and the second pipe 542 are rigid pipes. The first pipe 541 and the second pipe 542 are connected through a rotary joint 543. The central axis of the rotary joint 543 is coaxial with the rotation axis of the hinge 70.

[0117] A swing frame 71 is hinged to the lifting frame 5. A ladle cover 72 is provided at one swing end of the swing frame 71, and a limiting end 73 is provided at the other swing end. A column 8 is provided on the rotating base 3 to interact with the swing frame 71 on one side of the hinge part 70, and a guide surface 43 is provided on the vertical frame 4 to interact with the limiting end 73. This enables the ladle cover 72 to close and open during the lifting process of the lifting frame 5. The power of the vertical drive mechanism 41 is used for the lifting of the lifting frame 5 and acts on the ladle cover 72 at the same time. This enables the ladle cover 72 to close automatically when the molten iron ladle 9 is transferred with the casting transfer car, and to open automatically during the tilting of the molten iron ladle 9 and the pouring of molten iron. This makes the casting transfer car more versatile and compact in structure, with a simple and reliable transmission structure.

[0118] The opening and closing process of the cover 72 of the pouring and transfer vehicle in this embodiment is as follows:

[0119] In the initial state, the driving end 801 of the column 8 on the rotating base 3 contacts the driving surface 74 and supports the swing frame 71 through the driving surface 74. At this time, the cover 72 is located above the hinge part 70, and the cover 72 is in the open state. Figure 10 As shown, the lifting frame 5 is at its lowest position at this time;

[0120] When the molten iron ladle 9 is positioned on the docking platform 11, the lifting frame 5 moves upward. During this movement, the contact position between the driving end 801 of the column 8 on the rotating base 3 and the driving surface 74 changes. Simultaneously, after the swing frame 71 rotates around the hinge 70, the ladle cover 72 descends and covers the molten iron ladle 9. The limiting end 73 rotates upward and contacts the guide surface 43. At this time, the lug of the molten iron ladle 9 is located in the slot 510 of the bracket 51, and the bottom of the molten iron ladle 9 is positioned on the docking platform 11. Figure 11 As shown, at this time, the ladle cover 72 covers the molten iron ladle 9, the casting transfer car can transfer the molten iron ladle 9, and the dust removal system 54 works to collect the smoke and dust inside the molten iron ladle 9;

[0121] When the casting and transfer vehicle is located at the slag removal station or in front of the casting machine, the lifting frame 5 continues to move upward. The limiting end 73 first slides on the guide surface 4301, the cover 72 swings upward and opens, and is located above the hinge part 70. The cover 72 rotates upward and opens at a certain angle, such as... Figure 12 As shown;

[0122] As the lifting frame 5 moves upward, the limiting end 73 slides along the guide surface 4301 towards the vertical surface 4302.
