Description

Technical Field

[0001] The utility model belongs to the technical field of electrolytic aluminum production, and particularly relates to a ladle and pipe lifting bracket lifting device. Background Art

[0002] The vacuum ladle is a commonly used auxiliary equipment in the electrolytic aluminum industry. The equipment consists of a ladle, a boom, an ejector, and a bag tube. When high-pressure compressed air is introduced into the ejector, a negative pressure of about 0.05 MPa is generated in the ladle. Under the action of atmospheric pressure, the high-temperature aluminum liquid is sucked into the ladle, completing the suction operation. The bag tube and the ladle are connected by a flange. Since the bag tube is mostly a casting and weighs 278 kg, strong bumps during transportation can cause the bag tube to break, the flange seal to be damaged, affecting the ladle seal, and increasing the cost of spare parts.

[0003] For example, the utility model patent with authorization publication number CN210676927U discloses a device for preventing deformation and fracture of a tube wrapped in a vacuum ladle for aluminum electrolysis. The device comprises a vacuum ladle and a tube wrapped on the vacuum ladle. The vacuum ladle is provided with a support, a support member is hinged on the support, and a clamping mechanism is provided on the tube wrapped. The support member is connected to the clamping mechanism, and the tube wrapped is supported by the vacuum ladle as a support point. The support member is fixed on the vacuum ladle on one side and fixed above the tube wrapped in the vacuum ladle on the other side, thereby supporting and fixing the tube wrapped, thereby preventing the tube from being deformed or fractured by vibration, gravity and the like under high temperature conditions, effectively extending the service life of the tube wrapped, and reducing production costs. However, the device is complicated to operate during installation, which is time-consuming and labor-intensive. Insufficient supporting force causes sealing failure at the flange, affecting the efficiency of aluminum production.

[0004] Therefore, we propose a lifting device for a pipe bag support that is simple and convenient to operate, saves time and effort, has a strong lifting force, and provides stable support, so as to solve the above-mentioned problems. Utility Model Content

[0024] The following describes in detail the lifting device of the pipe-lifting bracket of the utility model with reference to the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] like Figure 1 As shown,

[0027] The lifting device of the lifting bag and pipe wrapping bracket includes a cylindrical lifting bag 17, one side of the lifting bag 17 is provided with an aluminum pouring port 16, and the top of the aluminum pouring port 16 is provided with an aluminum pouring port pipe wrapping cover 15, one end of the aluminum pouring port pipe wrapping cover 15 is connected to the aluminum pouring port 16 by a hinge, and a clamping device is provided between the other end of the aluminum pouring port pipe wrapping cover 15 and the aluminum pouring port 16. This design not only ensures the sealing, but also facilitates the operator to pour or pour the aluminum liquid, ensuring the safety and convenience of operation during the pouring process. On the opposite side of the aluminum pouring port pipe wrapping cover 15, the lifting bag 17 is fixed with a pipe wrapping 19 by a flange bolt, and a carbon fiber sealing ring 20 is connected between the pipe wrapping 19 and the lifting bag 17 by a flange bolt. The connection method of the flange bolt and the carbon fiber sealing ring 20 ensures the tightness and leakage prevention of the connection. Such a design not only improves the reliability of the entire system, but also facilitates maintenance and inspection work.

[0028] The top of the ladle 17 is equipped with an openable lid 13, which is fixed to the ladle 17 by bolts. This design not only facilitates the inspection and maintenance of the internal structure, but also ensures the safe closure of the aluminum liquid during transportation or storage. The ladle 17 is provided with ear shafts 14 on both sides of the aluminum pouring port 16. The two ear shafts 14 serve as connection points and are respectively connected to one end of two booms 18, while the other end of the boom 18 is threadedly connected to the beam 12. The lifting ring 11 is installed at the top center of the beam 12. This installation method is achieved by a pin connection, so that the lifting ring 11 can rotate to both sides. This design allows greater flexibility and adjustment range to adapt to different lifting requirements.

[0029] Example 2

[0030] On the basis of Example 1:

[0031] like Figure 2 and Figure 5 As shown, the bottom end of the trapezoidal bracket 1 is installed on the lifting bag 17, and the first base 2 is welded and installed on the top thereof. The first base 2 is connected to the four-link 3 through a pin to ensure the stability of the movement. The other end of the four-link 3 is connected to the second base 6 through a pin. A clamping structure 25 is also provided on the top of the second base 6. The clamping structure 25 includes an arc-shaped plate 9. An arc-shaped buckle 10 is provided on the upper part of the arc-shaped plate 9. The upper arc-shaped buckle 10 and the arc-shaped plate 9 are fixedly connected to the bag tube 19 by bolts to provide additional support for the bag tube 19.

[0032] like Figure 4As shown in the figure, it is a structural schematic diagram of the connecting shaft 5. The connection points of the four-link 3 away from the first base 2 and the second base 6 are connected through the connecting shaft 5. A threaded hole 4 is passed through the middle of each connecting shaft 5. Each threaded hole 4 is spirally connected to the T-shaped screw 7. The end of the T-shaped screw 7 away from the four-link 3 is fixedly connected to the handwheel 8. The combination of the connecting shaft 5 and the T-shaped screw 7, combined with the operating interface of the handwheel 8, enables the operator to easily control the lifting and lowering of the four-link 3 by rotating the handwheel 8, thereby realizing precise adjustment of the height of the bag 19. This design not only simplifies the operating process, but also improves work efficiency and safety.

[0033] like Figure 3 As shown, in order to achieve better connection and fixation, the support seat 21 and the baffle 22 are welded to the lower part of the lifting bag 17. At the same time, a through hole 24 is opened on the surface of the baffle 22, and the through hole 24 is connected to the rotating shaft 23 through a pin. This design allows the rotating shaft 23 to rotate up to 90 degrees, providing more flexibility and convenience for lifting operations.

[0034] Example 3

[0035] On the basis of Example 1 or Example 2:

[0036] During actual operation, when it is necessary to replace the bag tube 19 for the lifting bag 17, the operator first rotates the handwheel 8 counterclockwise. At this time, the four-link 3 contracts, and the arc buckle 10 will separate. At this time, the trapezoidal bracket 1 will rotate and fall around the rotating shaft 23 under the action of gravity until the trapezoidal bracket 1 contacts the baffle 22 and stops falling, so that the trapezoidal bracket 1 remains parallel to the ground. After completing the bag tube 19 replacement operation, when the four-link 3 is restored, the trapezoidal bracket 1 is lifted upward so that the trapezoidal bracket 1 and the bag tube 19 are in a vertical state, and then the handwheel 8 is turned clockwise to raise the four-link 3 to a high position, and the bag tube 19 is lifted vertically to the required position to meet the support requirements. This process demonstrates the high degree of automation and humanized design of the device, which greatly reduces the intensity of manual labor and improves work efficiency.
