Description

Technical Field

[0001] The invention relates to the field of molten copper pouring, in particular to a molten copper hanging ladle pouring device. Background Art

[0002] Ladle pouring is an important step in the metal casting process, especially for the casting of copper and its alloys. In this process, molten copper is transferred from the smelting furnace to a ladle (also called a tundish or ladle), through which the copper is then poured into a mold to form the desired casting.

[0003] However, most of the existing copper ladle pouring devices use a crane to drive a lifting platform to lift the copper ladle, but the lifting platform and the copper ladle are mostly connected by a hook driven by a worker, which is prone to false hooks, thus causing accidents, and the slag removal work of the copper water is also completed by manual operation, which is inefficient and also has certain safety hazards. Summary of the invention

[0004] In view of the shortcomings or deficiencies of the above-mentioned prior art, the present invention provides a copper molten ladle pouring device, which can limit the copper molten ladle more stably, making the pouring operation safer, and can automatically add a slag remover into the copper molten water and filter the scum in the copper molten water, thereby improving the pouring efficiency of the copper molten ladle.

[0005] A copper molten ladle pouring device comprises a lifting platform, two hook frames are fixedly connected to the lifting platform, the two hook frames are symmetrically arranged, a double-axis motor is fixedly connected to the top of the lifting platform, a clamping assembly is arranged on the lifting platform, and a pouring assembly is arranged on the lifting platform.

[0006] Furthermore, the clamping assembly includes a clamping arm, and two of the clamping arms are slidably connected to the lifting platform, the two clamping arms are symmetrically arranged, a threaded rod is threadedly connected between the two clamping arms, a transmission assembly is provided between one of the output shafts of the dual-axis motor and the threaded rod, the transmission assembly is composed of a driving wheel, a transmission wheel and a belt, a driving wheel is fixedly connected to one of the output shafts of the dual-axis motor, a transmission wheel is fixedly connected to the threaded rod, a belt is sleeved between the driving wheel and the transmission wheel, a limiting plate is fixedly connected to the lower part of the two clamping arms on the side close to each other, and two clamping frames and a supporting frame are slidably connected to the side close to each other. The two brackets on the same limiting plate form a group, a return spring is connected between the bracket and the limiting plate, a drop rack is fixedly connected to the bracket, a transmission rack is fixedly connected to the bracket, a transmission gear is fixedly connected to the sides of the two limiting plates close to each other, the transmission gear is meshed with the two transmission racks of the same group, the transmission gear is meshed with the drop rack, a clamping ring is placed on the two brackets, the clamping ring is located between the two brackets of the same group, two clamping grooves are formed on the clamping ring, a copper water bag is rotatably connected between the two clamping rings, two barrel ears are provided on the copper water bag, and an annular hoop is fixedly connected to the bottom of the copper water bag.

[0007] Furthermore, the casting assembly includes a winch, which is fixedly connected to the lifting platform, and the winch is fixedly connected to the other output shaft of the dual-axis motor. A pulley is rotatably connected to the lifting platform, and a steel cable is wound on the winch. A clamp is provided at the end of the steel cable, and the steel cable passes around the pulley. A spherical clamp is sleeved on the annular hoop, and the spherical clamp is clamped with the clamp at the end of the steel cable.

[0008] Furthermore, it also includes a slag removal component, which is arranged on the lifting platform, and the slag removal component includes a slag filter frame, the slag filter frame is clamped on the copper water ladle, and a slag blocking plate is fixedly connected to the slag filter frame, and a powder box is fixedly connected to the lifting platform, and five spreading troughs are opened at the bottom of the powder box, and a rotating shaft is rotatably connected to the powder box, and a circular sealing plate is fixedly connected to the bottom of the rotating shaft, and five material passages are opened on the circular sealing plate, and the top of the circular sealing plate contacts the bottom of the powder box, and a scraper is fixedly connected to the rotating shaft, and the scraper is located inside the powder box, and the bottom of the scraper contacts the bottom of the inner wall of the powder box, and the top of the rotating shaft is fixedly connected to a bevel gear disk, and a bevel gear is fixedly connected to the threaded rod, and the bevel gear is meshed with the bevel gear disk.

[0009] The beneficial effects are: first, the crane will drive the lifting platform to move above the copper water ladle and move downward, then the servo motor will drive the two clamps in the same group to limit the clamping ring, then the staff will connect the steel cable to the spherical clamp block, and then the crane will drive the lifting platform and the copper water ladle to continue to move upward and horizontally to the appropriate position, and then the dual-axis motor will drive the copper water in the copper water ladle to be poured into the designated mold. In this way, the two clamping rings are limited by two groups of clamps respectively, which can limit the copper water ladle more stably, thereby making the pouring operation safer.

[0010] When the dual-axis motor drives the threaded rod to rotate, the slag remover in the powder box will fall down to the surface of the molten copper in the copper ladle through the five feeding ports on the circular sealing plate, so that the slag in the molten copper floats to the surface of the molten copper. The rotation of the scraper will scrape the slag remover in the powder box. When the molten copper in the copper ladle is poured into the mold, the slag filter frame will filter the slag in the molten copper. As the copper ladle swings, the slag baffle plate will block the slag in the slag filter frame. In this way, the slag remover can be automatically added into the molten copper, and the slag in the molten copper can also be filtered, thereby improving the pouring efficiency of the copper ladle.
