Description

Technical Field

[0001] The utility model relates to the technical field of smelting, and particularly relates to a ladle automatic pouring device. Background Art

[0002] At present, steel mills on the market are divided into ordinary steel mills and special steel mills. Ordinary steel mills, such as Shanghai Baoshan Iron and Steel Plant, mostly smelt iron ore, and most of the iron ore is imported from countries such as Australia, so the proportion is not large. Special steel mills mostly use recycled waste steel mills for separation and smelting. The steel smelted in this way is more suitable for production and living needs because of multiple smelting processes.

[0003] At present, cast iron is poured by lifting it with a crane and then manually rotating the tilting device by workers to tilt the pouring bucket for pouring. The molten steel has a high temperature, and manual operation has low safety, a poor working environment, and requires multiple workers to operate with full concentration. Therefore, we designed a ladle transfer pouring device.

[0004] Therefore, an automatic ladle pouring device is used to solve the above problems. Summary of the Invention

[0005] The purpose of the utility model is to provide an automatic ladle pouring device to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: including a pouring bucket, rotating sleeves are symmetrically arranged on the outer cylindrical surface of the pouring bucket, a connecting rod is installed on the outer cylindrical surface of the rotating sleeve, a cross bar is installed between the two connecting rods, an inclination mechanism is arranged at one end of the connecting rod, the rotating end of the inclination mechanism penetrates through the rotating sleeve and is connected to the pouring bucket, and the inclination mechanism is used for tilting the pouring bucket.

[0007] Preferably, a lifting lug is arranged at the top of the cross bar.

[0008] Preferably, buckles are symmetrically arranged on the opposite surfaces of the two connecting rods.

[0009] Preferably, the inclination mechanism includes an installation box, the installation box is installed outside the connecting rod, a support plate is arranged on one side of the installation box, a motor is arranged at the top of the support plate, the output end of the motor penetrates through one side of the installation box and is connected to a connecting shaft, a connecting plate is connected to the end of the connecting shaft away from the motor, and a sliding rod is arranged on the side of the connecting plate away from the connecting shaft.

[0011] Preferably, an installation sleeve is provided at the bottom end of the sliding rod. A rotating shaft is provided inside the installation sleeve. The rotating shaft is arranged inside the installation box.

[0012] The technical effects and advantages of the present utility model:

[0013] 1. After the pouring bucket is higher than the horizontal plane, the motor drives the connecting shaft to rotate. The connecting shaft drives one end of the connecting plate to rotate. The other end of the connecting plate slides inside the sliding rod. At the same time, it drives the sliding rod to swing left and right. The sliding rod of the connecting plate slides inside the chute of the sliding rod. While the sliding rod slides in the chute, it drives the sliding rod to swing. When the sliding rod swings, it drives the rotating shaft to swing and slide inside the chute. The sliding rod and the rotating shaft, one above the other, both slide inside the chute. While the rotating shaft rotates and swings, it drives the connecting column to swing. The other end of the connecting column drives the connecting block to rotate. Since the connecting column and the connecting block are integrally cast, therefore, when the rotating shaft swings, the other end of the connecting column slides with the connecting block. The connecting block passes through the rotating sleeve and is connected to the pouring bucket. The connecting block drives the pouring bucket to tilt, pouring the materials inside the pouring bucket. Driven by the motor, the staff is removed from the previous post, improving the safety of operation and reducing the life risk to the staff at the same time.

Detailed implementation mode

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0020] At present, the steel mills on the market are divided into ordinary steel mills and special steel mills. Ordinary steel mills such as Shanghai Baoshan Iron and Steel Plant mostly smelt iron ore, and most of the iron ore is imported from countries such as Australia, so the proportion is not large. Special steel mills mostly use recycled waste steel mills for separation and smelting. The steel smelted in this way is more suitable for production and living needs because of multiple smelting processes.

[0021] At present, cast iron is poured by being lifted by a crane and then the tilting device is manually rotated by workers to tilt the pouring ladle for pouring. The molten steel has a high temperature, the manual operation has low safety, the working environment is poor, and multiple workers need to concentrate on the operation. Therefore, we designed a ladle transfer pouring device.

[0022] The present invention provides a Figures 1 to 3 kind of ladle automatic pouring device as shown, including a pouring ladle 1. Rotating sleeves 2 are symmetrically arranged on the outer circular surface of the pouring ladle 1. Connecting rods 3 are installed on the outer circular surface of the rotating sleeves 2. A cross bar 4 is installed between the two connecting rods 3. One end of the connecting rod 3 is provided with a tilting mechanism 5. The rotating end of the tilting mechanism 5 passes through the rotating sleeve 2 and is connected to the pouring ladle 1. The tilting mechanism 5 is used for tilting the pouring ladle 1.

[0023] When in use, the tilting mechanism 5 drives the pouring ladle 1 to tilt through the rotating sleeve 2, so that the pouring ladle 1 is convenient for pouring out the internal materials. The connecting rod 3 and the cross bar 4 form a hoisting mechanism, which is convenient for moving and pouring the pouring ladle 1.

[0024] A lifting lug 7 is arranged at the top of the cross bar 4.

[0025] When in use, it is connected to the lifting lug 7 through an external hoisting device to move the whole pouring ladle 1 and make it perform actions higher than the horizontal plane.

[0026] Snap fasteners 6 are symmetrically arranged on opposite faces of the two connecting rods 3.

[0027] During use, when the pouring bucket 1 needs to be carried or transported to a position where the hoisting device cannot reach, the handling device inserts into the interior of the snap fastener 6 and performs an action above the horizontal plane on the entire pouring bucket 1. Since snap fasteners 6 are provided on both sides, the handling device applies a lifting force to the two snap fasteners 6, so that the pouring bucket 1 remains balanced during the lifting process, preventing the material from shaking in the pouring bucket 1 or spilling outside the pouring bucket 1.

[0028] One end of the snap fastener 6 away from the connecting rod 3 is C-shaped, enabling the snap fastener 6 to be buckled on the end face of the handling device, preventing the pouring bucket 1 from shaking during lifting or handling, which may cause the pouring bucket 1 to disengage from the handling device and result in production accidents.

[0029] The tilting mechanism 5 includes a mounting box 501, which is mounted on the outside of the connecting rod 3. One side of the mounting box 501 is provided with a support plate 502, and the top of the support plate 502 is provided with a motor 503. The output end of the motor 503 passes through one side of the mounting box 501 and is connected to a connecting shaft 504. The end of the connecting shaft 504 away from the motor 503 is connected to a connecting plate 507, and a sliding rod 508 is provided on the side of the connecting plate 507 away from the connecting shaft 504.

[0030] During use, the mounting box 501 is supported by the connecting rod 3 and is connected to the rotating sleeve 2. Then, the support plate 502 supports the motor 503, providing a support force for the motor 503. The motor 503 drives the connecting shaft 504 to rotate, and the connecting shaft 504 drives one end of the connecting plate 507 to rotate. The other end of the connecting plate 507 slides inside the sliding rod 508, and at the same time, drives the sliding rod 508 to swing left and right.

[0031] A through chute is provided on the end face of the sliding rod 508. A sliding rod is provided on the side of the connecting plate 507 away from the connecting shaft 504, and the sliding rod slides in the chute of the sliding rod 508. A rotating shaft 509 is provided above the sliding rod, and a connecting column 5010 is provided on the other side of the rotating shaft 509. A connecting block 5011 is provided at the bottom end of the connecting column 5010, and a sleeve shaft 5012 is provided at the other end of the connecting block 5011. The sleeve shaft 5012 rotates inside the rotating sleeve 2.

[0032] During use, the sliding rod of the connecting plate 507 slides inside the chute of the sliding rod 508. While the sliding rod slides in the chute, it drives the sliding rod 508 to swing. When the sliding rod 508 swings, it drives the rotating shaft 509 to swing and slide inside the chute. While the rotating shaft 509 rotates and swings, it drives the connecting column 5010 to swing. The other end of the connecting column 5010 drives the connecting block 5011 to rotate. Since the connecting column 5010 and the connecting block 5011 are integrally cast, when the rotating shaft 509 swings, the other end of the connecting column 5010 slides with the connecting block 5011. The connecting block 5011 passes through the rotating sleeve 2 and is connected to the pouring bucket 1, and the connecting block 5011 drives the pouring bucket 1 to tilt, pouring the materials inside the pouring bucket 1.

[0033] An installation sleeve 506 is provided at the bottom end of the sliding rod 508, and a rotating shaft 505 is provided inside the installation sleeve 506. The rotating shaft 505 is arranged inside the installation box 501.

[0034] During use, while the sliding rod 508 swings, it drives the installation sleeve 506 to slide around the rotating shaft 505. The rotating shaft 505 is arranged inside the installation box 501, and the installation box 501 fixes the rotating shaft 505 to prevent the rotating shaft 505 from shifting in position during rotation, affecting the overall operation of the tilting mechanism 5.

[0035] Working principle

[0036] The pouring bucket 1 is moved to the designated position through the lifting lug 7. Then, the lifting device lifts the pouring bucket 1 through the lifting lug 7, facilitating the action of the tilting mechanism 5 on the pouring bucket 1 to tilt the pouring bucket 1 and pour the materials inside the pouring bucket 1.

[0037] After the pouring bucket 1 is higher than the horizontal plane, the motor 503 drives the connecting shaft 504 to rotate. The connecting shaft 504 drives one end of the connecting plate 507 to rotate. The other end of the connecting plate 507 slides inside the sliding rod 508. At the same time, it drives the sliding rod 508 to swing left and right. The sliding rod of the connecting plate 507 slides inside the chute of the sliding rod 508. While the sliding rod slides in the chute, it drives the sliding rod 508 to swing. When the sliding rod 508 swings, it drives the rotating shaft 509 to swing and slide inside the chute. The sliding rod and the rotating shaft 509 slide inside the chute, one above the other. While the rotating shaft 509 rotates and swings, it drives the connecting column 5010 to swing. The other end of the connecting column 5010 drives the connecting block 5011 to rotate. Since the connecting column 5010 and the connecting block 5011 are integrally cast, when the rotating shaft 509 swings, the other end of the connecting column 5010 slides with the connecting block 5011. The connecting block 5011 passes through the rotating sleeve 2 and is connected to the pouring bucket 1, and the connecting block 5011 drives the pouring bucket 1 to tilt, pouring the materials inside the pouring bucket 1.

[0038] While the sliding rod 508 is swinging, it drives the mounting sleeve 506 to slide around the rotating shaft 505. The rotating shaft 505 is arranged inside the mounting box 501, and the mounting box 501 fixes the rotating shaft 505 to prevent the position deviation of the rotating shaft 505 during rotation, which affects the overall operation of the tilting mechanism 5.

[0039] When the pouring bucket 1 needs to be transported or conveyed to a position where the hoisting device cannot reach, the handling device extends into the inside of the buckle 6 and makes an action higher than the horizontal plane on the whole pouring bucket 1. Since the buckles 6 are arranged on both sides, the handling device applies a lifting force to the two buckles 6, so that the pouring bucket 1 remains balanced during the lifting process, avoiding the shaking of the materials in the pouring bucket 1 or spilling them outside the pouring bucket 1.

[0040] One end of the buckle 6 far from the connecting rod 3 is C-shaped, so that the buckle 6 is buckled on the end face of the handling device, avoiding the shaking of the pouring bucket 1 during lifting or transportation, resulting in the pouring bucket 1 detaching from the handling device and causing production accidents.

[0041] Note: The handling device is preferably a forklift, the connecting block 5011 is used as a shaft to connect with the pouring bucket 1, and the hoisting device is preferably a gantry crane.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
