The tipping device dumps the molten iron ladle and adds molten iron to the ladle behind the furnace. Molten iron is added once for each smelting process.

[0003] The existing tipping device is that the main hook of the crane lifts the hanging arm of the molten iron ladle, and the auxiliary hook drives the side ears of the molten iron ladle to rise, so as to tilt the molten iron ladle to dump the molten iron.

Detailed implementation manners

[0028] In order to make the objectives, technical solutions and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings for the convenience of those skilled in the art to understand.

[0029] As shown in the figure, a ladle automatic tilting device includes a base 1, a mounting rod 2, a lifting hydraulic rod 3, a guide rail 4, and a tilting hydraulic rod 5; on the base 1, two vertically installed lifting hydraulic rods 3 are arranged in pairs. There are two lifting hydraulic rods 3, and the tilting space of the ladle 8 is between the two lifting hydraulic rods 3. The upper end of the piston rod of the lifting hydraulic rod 3 is provided with a guide rail 4, and the guide rail 4 is arranged parallel to the ground and extends forward and backward from the fulcrum of the lifting hydraulic rod 3 as the center.

[0030] Between the two guide rails 4, there are two suspension mechanisms 6 that can move back and forth. The suspension mechanism 6 in the front is used to suspend the ladle 8, and on the suspension mechanism 6 in the rear, a tilting hydraulic rod 5 is provided through the mounting rod 2. The suspension mechanism 6 includes a load - bearing wheel 6 - 1, a connecting rod 6 - 2, and a U - shaped frame 6 - 3; there are two U - shaped frames 6 - 3, which are respectively installed on the two guide rails 4 through the load - bearing wheels 6 - 1. The load - bearing wheels 6 - 1 are rotatably installed on both sides of the U - shaped frame 6 - 3, and the two U - shaped frames 6 - 3 are connected into one body through the connecting rod 6 - 2; both ends of the mounting rod 2 are respectively inserted into the grooves of the U - shaped frame 6 - 3, so as to firmly connect the mounting rod 2 with the U - shaped frame 6 - 3. The tilting hydraulic rod 5 is fixedly installed on the mounting rod 2 through bolts. A hanging arm 8 - 2 is hinged on the ladle 8, and a hanging head 8 - 3 that can be placed in the recess of the U - shaped frame 6 - 3 is provided on the hanging arm 8 - 2. When placing the ladle 8, use a crane to hook the hanging arm 8 - 2 to carry the ladle 8. After placing the ladle 8 between the two lifting hydraulic rods 3, put the hanging head 8 - 3 on the hanging arm 8 - 2 into the recess of the U - shaped frame 6 - 3 to firmly connect the hanging arm 8 - 2 with the U - shaped frame 6 - 3, so as to suspend the ladle 8 on the suspension mechanism 6, and the ladle 8 is convenient to place. Preferably, the cross - section of the guide rail 4 is in a "C" shape, and the two guide rails 4 are arranged oppositely, clamping the suspension mechanism 6 from both sides to ensure the stability of the suspension mechanism 6.

[0031] The two suspension mechanisms 6 are driven to move forward and backward respectively by a driving element 7 arranged on the guide rail 4. The driving element 7 adopts a linear driving component such as a hydraulic rod or an electric telescopic rod. Preferably, the driving element 7 adopts a hydraulic rod. The base of the hydraulic rod is fixedly mounted on the guide rail 4 through a rod. The telescopic rod of the hydraulic rod is connected to the suspension mechanism 6. When the hydraulic rod is extended or shortened, the suspension mechanism 6 is driven to move forward and backward along the guide rail 4. A tilting hook 11 is provided on the telescopic rod of the tilting hydraulic rod 5 through a steel rope. A flexible connection is formed by the steel rope, which effectively reduces the difficulty of hanging the tilting hook 11 on the hanging ear 8-1. A hanging ear 8-1 is provided at the bottom of the ladle 8. During operation, after the iron ladle 8 filled with molten iron is hung on the hanging mechanism 6, the tipping hook 1 is hung on the hanging ear 8-1 of the iron ladle 8; when pouring the molten iron, the lifting hydraulic rod 3 is slowly lifted, and the tipping hydraulic rod 5 pulls the bottom of the iron ladle 8 to lift, and the lifting speed of the tipping hydraulic rod 5 is greater than the lifting speed of the lifting hydraulic rod 3, thereby lifting the bottom of the iron ladle 8 and starting to pour the molten iron. At the same time, the driving element 7 drives the hanging mechanism 6 to move, so that the entire iron ladle 8 slowly rotates and tilts with the pouring port of the molten iron as the center, effectively ensuring that the position of the pouring port of the iron ladle 8 remains unchanged during the entire pouring process, making it convenient for the staff to accurately pour the molten iron into the ladle. After adjusting the position of the base 1, the outlet of the molten iron will not change during the entire pouring process, so that the molten iron in the iron ladle 8 can be poured out all at once without the need for secondary adjustment, effectively improving the efficiency of adding molten iron. The suspension mechanism 6 can be driven to move by the driving element 7, and the position of the suspension mechanism 6 can be adjusted so that the hanging arm 8-2 and the steel rope of the tipping hydraulic rod 5 are always in a vertical state, so that the force direction of the molten iron ladle 8 is always in a vertical state. Compared with the combined hook tipping in the conventional technical field, the force on the molten iron ladle 8 does not have an inclined force, which effectively avoids the molten iron ladle 8 from shaking back and forth when dumping the molten iron, and effectively improves the safety and stability of the process of dumping the molten iron and adding iron.

[0032] In this embodiment, the lifting hydraulic rod 3 is provided with a laser rangefinder I9 for detecting the height of the guide rail 4. The light source emitting unit of the laser rangefinder I9 is ​​fixedly mounted on the top of the lifting hydraulic rod 3, and the reflector of the laser rangefinder I9 is ​​fixedly mounted on the bottom of the guide rail 4. The distance between the guide rail 4 and the light source emitting unit of the laser rangefinder I9 is ​​detected by the laser rangefinder I9 with the lifting hydraulic rod 3 in the unextended state as the origin, thereby obtaining the height of the guide rail 4. The guide rail 4 is provided with a laser rangefinder II10 for detecting the position of the suspension mechanism 6. There are two laser rangefinders II10, which are respectively set in one-to-one correspondence with the two suspension mechanisms 6, and the detection method is the same as that of the laser rangefinder I9. A laser rangefinder III19 for detecting the position of the tilting hook 11 is provided on the tilting hydraulic rod 5. The light source emitting unit of the laser rangefinder III19 is fixedly mounted on the base of the tilting hydraulic rod 5, and the reflecting sheet of the laser rangefinder III19 is fixedly mounted on the top of the telescopic rod of the tilting hydraulic rod 5. The laser rangefinder III19 detects the distance between the top of the telescopic rod of the tilting hydraulic rod 5 and the light source emitting unit of the laser rangefinder III19, thereby obtaining the elongation of the tilting hydraulic rod 5 and obtaining the position signal of the tilting hook 11. Laser rangefinder I9, laser rangefinder II10, and laser rangefinder III19 are respectively connected to the signal input end of the controller 12, and the controller 12 is respectively electrically connected to the driving element 7, the lifting hydraulic rod 3, and the tilting hydraulic rod 5. When pouring molten iron, the laser rangefinder I9 transmits the position of the guide rail 4 to the controller 12 in real time, that is, the distance the guide rail 4 is displaced upward, and then transmits it to the controller 12. The laser rangefinder II10 detects the displacement distance of the suspension mechanism 6 in real time and transmits it to the controller 12. The laser rangefinder III19 detects the elongation of the tilting hydraulic rod 5 in real time, and then the controller 12 synchronously controls and coordinates the operation of the driving element 7, the lifting hydraulic rod 3, and the tilting hydraulic rod 5, effectively ensuring that the ladle 8 can rotate with the pouring port as the center to pour the molten iron, with more precise control and higher safety.

[0033] Preferably, a weighing sensor 13 is provided at the bottom of the depression of the U-shaped frame 6-3, and the mounting rod 2 is placed on the weighing sensor 13, so as to obtain the total force of the suspension mechanism 6 located in the front. After the ladle 8 is placed on the suspension mechanism 6, the hanging head 8-3 is pressed on the weighing sensor 13, so as to obtain the total force of the suspension mechanism 6 located in the front; the weighing sensor 13 is connected to the signal input end of the controller 12, and the signal output end of the controller 12 is connected to the sound and light alarm 14. When the ladle 8 is not placed, the force of the four weighing sensors 13 is zero. After the ladle 8 is placed, the sum of the values ​​of the four weighing sensors 13 is the total weight of the ladle 8, so as to obtain the real-time total weight of the ladle 8. The total weight change of the ladle 8 is the amount of molten iron dumped, which is convenient for the staff to monitor the amount of molten iron dumped by the ladle 8 in real time. At the same time, by comparing the total forces of the two weighing sensors 13 on the same side, it is possible to determine whether the ladle 8 is tilted to the side. If the ladle 8 is tilted to the side, the controller 12 can be used to control the lifting hydraulic rod 3 in the tilting direction to rise appropriately, and the force on the ladle 8 can be readjusted to effectively ensure that the force on the ladle 8 is uniform and the safe process of pouring the molten iron is ensured. If the tilt of the ladle 8 exceeds the set value, the controller 12 controls the sound and light alarm 14 to send an alarm signal to promptly remind the staff to evacuate, thereby effectively ensuring the personal safety of the staff.

[0034] Preferably, the controller 12 is connected to the background control system through a wireless communication module. The background control system consists of a server and an operation panel. When working, the controller 12 transmits various signals of the device to the background control system through the wireless communication module, and the background control system stores the signals to facilitate the staff to check them later. At the same time, the staff can input the corresponding control parameters through the background control system to control the device. For example, after the amount of molten iron to be dumped is input, the controller receives the corresponding control signal and controls the drive element 7, the lifting hydraulic rod 3, and the tipping hydraulic rod 5 to work together to dump the molten iron from the ladle. The weighing sensor 13 transmits the real-time weight of the ladle to the controller 12. When the weight of the ladle is reduced to the set weight, the controller 12 controls each component to stop moving, thereby adding a certain amount of molten iron into the ladle.

[0035] In this embodiment, a counterweight block 1-1 is provided at the rear end of the base 1. The center of gravity of the base 1 is adjusted by the counterweight block 1-1, which can effectively avoid the overturning problem caused by the unstable center of gravity of the base 1. The upper end of the reinforcing rod 1-2 is connected to the upper end of the lifting hydraulic rod 3, and the lower end is connected to the base 1. The reinforcing rod 1-2, the base 1, and the lifting hydraulic rod 3 form a triangle, which effectively improves the stability of the lifting hydraulic rod 3.

[0036] In this embodiment, a guide groove 15 is provided on the inner side of the lifting hydraulic rod 3, and the outer frame of the guide groove 15 is fixedly connected to the lifting hydraulic rod 3. The guide groove 15 is an arc shape with the pouring port of the molten iron ladle 8 as a circle. A guide wheel 17 matching the guide groove 15 is provided on the side of the molten iron ladle 8. The lower end of the guide groove 15 is provided with an opening for placing the guide wheel 17 into the guide groove 15. When pouring molten iron, the molten iron ladle 8 tilts, and the guide wheel 17 moves upward along the guide groove 15, thereby limiting the tilting trajectory of the molten iron ladle 8, ensuring the stability of the tilting of the molten iron ladle 8, and at the same time, effectively preventing the molten iron ladle 8 from shaking back and forth, ensuring the stability of the molten iron ladle 8 when the base 1 moves. Preferably, a scale is provided on the guide groove 15 to facilitate the staff to check the tilt angle of the molten iron ladle 8 in real time.

[0037] In this embodiment, a dust cover 18 is provided on the guide rail 4, and the top of the dust cover 18 is connected to the exhaust fan 16 through a pipeline. When pouring molten iron, the dust cover 18 is located just above the electric furnace. The exhaust fan 16 works and forms a negative pressure under the dust cover 18 through the pipeline, which sucks away the smoke generated when pouring the molten iron, and then introduces it into an external smoke treatment device, effectively reducing the amount of smoke around the equipment and reducing environmental pollution.

[0038] Working process of the present invention:

[0039] 1. Place the ladle, use the crane to hook the hanging arm 8-2 to carry the ladle 8, put the ladle 8 between the two lifting hydraulic rods 3, and then put the hanging head 8-3 on the hanging arm 8-2 into the depression of the U-shaped frame 6-3;

[0040] 2. Dumping molten iron: input the required amount of molten iron to be dumped through the background control system, and the weighing sensor 13 transmits the total weight of the molten iron ladle 8 to the controller 12 in real time. The controller 12 synchronously controls and coordinates the driving element 7, the lifting hydraulic rod 3, and the tilting hydraulic rod 5 to rotate the molten iron ladle 8 with the dumping port as the center to dump the molten iron. When the total weight reduction of the molten iron ladle 8 is consistent with the set amount, the controller 12 controls each element to stop and reset, and the molten iron dumping is completed. At the same time, during the process of dumping molten iron, the exhaust fan 16 works, and a negative pressure is formed under the dust cover 18 through the pipeline to suck away the smoke and dust generated when dumping molten iron.

[0041] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention; the dimensions of the drawings are independent of the specific objects, and the dimensions of the objects can be changed arbitrarily.
