Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, specifically to a lifting device for removing aluminum from a crucible. Background Technology

[0002] Currently, most existing aluminum unloading devices for crucibles employ a fixed frame structure combined with a simple lifting device. A winch or hydraulic lifting mechanism drives the lifting device to achieve longitudinal displacement, thereby completing the lifting and unloading of the aluminum block from the crucible. This type of device has found some application in small laboratories or low-volume production scenarios, and its simple structure and low manufacturing cost make it suitable for certain applications.

[0003] However, with the expansion of industrial production scale and the continuous improvement of operational safety requirements, existing lifting devices have gradually revealed many technical defects. First, the existing devices lack an effective guiding and restraining structure between the moving parts and the fixed frame. When the lifting device carries aluminum blocks (typically weighing hundreds of kilograms or even several tons) for lifting operations, the moving frame is easily affected by factors such as the shift of the aluminum block's center of gravity, wind force, and vibrations from the lifting mechanism, resulting in lateral swaying or displacement. This swaying may not only cause the aluminum block to collide with the inner wall of the crucible, causing damage to the crucible and scratches on the surface of the aluminum block, but may also lead to serious safety accidents such as the aluminum block falling off, threatening the personal safety of operators and the integrity of production equipment.

[0004] Secondly, the operational efficiency and reliability are insufficient to meet the demands of large-scale production. Due to insufficient stability, operators need to reduce the lifting speed to control the swaying amplitude, which increases the time required for each aluminum tapping operation. At the same time, the additional stress generated by the swaying will act on the lifting mechanism and the connection parts of the lifting device, aggravating component wear, shortening the service life of the equipment, and increasing equipment maintenance costs and downtime. Utility Model Content

[0005] To address the aforementioned issues, this utility model provides a lifting device for removing aluminum from a crucible. The device utilizes a movable frame to drive the lifting device to perform longitudinal displacement, thereby completing the aluminum block removal operation. A guide component is used to enhance the stability of the movable frame during lifting.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a lifting device for removing aluminum from a crucible, comprising a mobile trolley, a lifting module disposed in the middle of the mobile trolley, a pull-out seat disposed below the lifting module, the lifting module comprising a fixed frame and a movable frame, a lifting push rod disposed in the middle of the fixed frame, a guide component disposed on the inner side of the fixed frame, and a limit component disposed on the outer side.

[0007] As a further improvement to the above technical solution: The guide assembly includes a guide rail, the side wall of which is provided with a slot, and the movable frame is provided with a slider that cooperates with the guide rail.

[0008] The guide rails are four in number and are evenly distributed on the four legs of the fixed frame.

[0009] The limiting component includes a limiting plate one and a limiting plate two respectively disposed on the fixed frame, and the movable frame is provided with buffers that cooperate with the limiting plate one and the limiting plate two respectively.

[0010] The upper part of the fixed frame is provided with a mounting bracket for connecting to the mobile trolley, and the lower part is provided with a support platform for installing the lifting push rod.

[0011] The movable frame is slidably connected to the fixed frame, and a crossbeam for connecting the movable end of the lifting push rod is provided in the middle of the movable frame.

[0012] The beneficial effects of this utility model embodiment are as follows: The aluminum unloading lifting device for the crucible includes a mobile trolley mounted on a bridge frame. A lifting module is assembled in the middle of the mobile trolley, and a pull-out seat for mounting the lifting rod is provided below the lifting module. The lifting module consists of a fixed frame and a movable frame that are slidably installed. A lifting push rod is installed in the middle of the fixed frame, a guide component is configured on the inner side, and a limiting component is provided on the outer side. The movable frame drives the lifting device to make longitudinal displacement, thereby completing the aluminum block unloading operation. The guide component improves the stability of the movable frame during lifting, especially when the aluminum block has a high degree of adhesion to the inner wall of the crucible, which can more effectively prevent the instability of the entire lifting device and avoid the phenomenon of the aluminum block slipping off after sliding, thus ensuring the stability and safety of the lifting operation.

[0015] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0016] like Figure 1-4 As shown, the aluminum unloading device for the crucible in this embodiment includes a mobile trolley 1 mounted on a bridge. A lifting module is mounted in the middle of the mobile trolley 1, and a pull-out seat 2 for mounting the lifting rod is provided below the lifting module. The lifting module consists of a fixed frame 3 and a movable frame 4 slidably installed. A lifting push rod 5 is installed in the middle of the fixed frame 3, with a guide component on the inner side and a limiting component on the outer side. The movable frame 4 drives the lifting device to make longitudinal displacement, thereby completing the aluminum block unloading operation. The guide component improves the stability of the movable frame 4 during lifting, especially when the aluminum block has a high adhesion to the inner wall of the crucible, which can more effectively prevent the stability of the entire lifting device from slipping and causing the aluminum block to slip off, thus ensuring the stability and safety of the lifting operation.

[0017] The guiding assembly includes a guide rail 6 detachably connected to the fixed frame 3. The side wall of the guide rail 6 has a slot 7, and a slider 8 adapted to the guide rail 6 is installed on the movable frame 4. There are four guide rails 6 in total, evenly distributed on the four legs of the fixed frame 3.

[0018] The limiting components include a first limiting plate 9 and a second limiting plate 10 respectively installed on the fixed frame 3, which are used to limit the maximum lifting range of the movable frame 4. The movable frame 4 is provided with a buffer 11 that works in conjunction with the first limiting plate 9 and the second limiting plate 10 to prevent shaking after a hard collision when the movable stroke reaches the limited position, which could cause the aluminum block to fall off.

[0019] The upper end of the fixed frame 3 is provided with a mounting bracket 12 for connecting with the mobile trolley 1, and the lower part is provided with a support platform 13 for installing the lifting push rod 5. The movable frame 4 is slidably connected to the fixed frame 3, and a crossbeam 14 is provided in the middle of it, which is used to connect the movable end of the lifting push rod 5.

[0020] The working principle of this scheme is as follows: First, the lifting push rod 5 extends downward, driving the movable frame 4 to move down and complete the docking of the lifting rod with the central lifting hole of the aluminum block. When the lifting rod and the aluminum block are connected, the lifting push rod 5 returns to its original position, and the movable frame 4 moves upward synchronously, providing an upward pulling force for the separation of the aluminum block and the crucible. The guide component can improve the movement stability of the movable frame 4 and prevent the aluminum block from falling off. In particular, the vibration generated at the moment of separation of the aluminum block and the crucible can also be buffered by the guide rail 6 to ensure the stable operation of the lifting operation.
