Description

Technical Field

[0001] The invention relates to an aluminum pouring device, in particular to a mobile aluminum liquid ladle aluminum pouring device. Background Art

[0002] The vacuum ladle casting system for molten aluminum is a key piece of equipment in electrolytic aluminum production, primarily used for the extraction and transfer of molten aluminum from the electrolytic cell. It operates by using compressed air to create a vacuum, allowing the molten aluminum to be drawn into the ladle under atmospheric pressure. Traditional aluminum casting systems utilize manual tilting and pouring, which is labor-intensive and presents significant safety risks. To address these technical issues, a fixed hydraulic system has been added to the casting system in recent years. A hydraulic drive unit is installed on the side of the casting furnace, integrating with a receiving box and a connecting launder for automated pouring. This system, controlled by a PLC, enables precise angle adjustment and accurate control of the molten aluminum flow rate.

[0003] However, this fixed hydraulic system presented several challenges. First, the entire system occupied a large space, with a total width exceeding 2.5 meters. This made it impractical to install in compact workshops with limited space and still required manual operation. Furthermore, in workshops with multiple casting furnaces, each furnace required its own hydraulic system, leading to duplicated aluminum injection equipment and increased equipment costs. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a mobile aluminum molten ladle aluminum pouring device, comprising a carrier, wherein a driving wheel is installed at the bottom of the carrier;

[0005] A support base is connected to the upper part of the vehicle through a lifting mechanism. The support base is provided with support legs on the side of the vehicle. The lifting mechanism is used to drive the support base to move vertically relative to the vehicle. When the support legs move downward, the support legs provide rigid support for the support base.

[0006] A tilting aluminum injection mechanism connected to the upper part of the support base;

[0007] The lifting mechanism includes a lifting assembly, a lifting hydraulic cylinder, and a lifting inclined block. The lifting inclined block is fixedly connected to the cargo carrier, and the lifting inclined block has an inclined guide surface; the fixed end of the lifting hydraulic cylinder is rotatably connected to the cargo carrier, and the driving end of the lifting hydraulic cylinder is rotatably connected to the lifting assembly. The lower part of the lifting assembly is in contact with the lifting inclined block, and the upper part of the lifting assembly is in contact with the bottom surface of the support seat.

[0008] Furthermore, the lifting assembly includes an upper wheel and a lower wheel, the lower wheel is in rolling contact with the guide surface, and the upper wheel is in rolling contact with the bottom of the support base, converting the rotational motion into a vertical lifting motion of the support base.

[0009] Furthermore, the upper wheel and the lower wheel are rotatably connected to a set of lifting beams, and the middle portion of the lifting beams is rotatably connected to the driving end of the lifting hydraulic cylinder.

[0010] Furthermore, when the support legs are grounded, there is a separation gap between the upper wheel and the bottom of the support seat.

[0011] Furthermore, the support legs are connected to the side surfaces of the vehicle with limiting wheels, and the limiting wheels are in rolling contact with the side surfaces of the vehicle.

[0012] Furthermore, a movable flow channel mechanism is installed on the support seat, and the movable flow channel mechanism includes an inclined guide channel, and the guide channel is movably connected to the support seat.

[0013] Furthermore, the aluminum liquid inlet of the guide trough is equipped with a dust collecting fan and a dust collecting hood.

[0014] Furthermore, the guide groove and the support seat gear rack structure are transmitted. A gear is provided above the support seat, and a rack arranged along the moving direction is installed at the bottom of the guide groove.

[0015] Furthermore, a guide rail extending along the translation direction is provided at the bottom of the guide trough, and a guide wheel is rotatably connected to the support seat, and the guide wheel is in rolling contact with the surface of the guide rail.

[0016] Furthermore, the support seat is provided with a rear support wheel on one side extending along the guide groove. When the guide groove is extended, the rear support wheel is in rolling contact with the bottom of the guide groove.

[0017] This invention provides a mobile aluminum ladle pouring device. The tilting and pouring mechanism is transported between aluminum casting furnaces via a carrier. The carrier is connected to the support base via a lifting mechanism driven by a hydraulic cylinder. The pouring device switches between a mobile and pouring state. In the mobile state, the device is supported by drive wheels at the bottom of the carrier; in the pouring state, the device is rigidly supported by support legs at the bottom of the support base. This allows a single device to cover multiple aluminum casting furnaces, eliminating the space occupation issue of the pouring device and improving the layout flexibility of the workshop.

[0018] At the same time, a retractable flow trough structure is provided in the embodiment, and the guide trough is movably connected to the carrier through a gear rack structure. The guide trough extends when aluminum is injected, expanding the aluminum injection space; when the carrier moves, the guide trough shrinks above the support seat, greatly reducing the space occupied by the equipment.

[0029] like Figures 1 to 3 The mobile aluminum ladle pouring device shown includes a carrier 1, a support base 12 connected to the top of the carrier 1, and a tilting mechanism 4 connected to the top of the support base 12. The tilting mechanism 4 is conventional and consists of an L-shaped tilting frame 41 and a tilting hydraulic cylinder 42. The aluminum ladle is mounted on the tilting frame 41, one end of which is pivotally connected to the top of the support base 12 via a tilting shaft 43. Normally, the tilting frame 41 lies flat, with one side parallel to the support base 12. The tilting hydraulic cylinder 42 is the driving component of the tilting frame 41. Its fixed end is pivotally connected to the support base 12, and its driving end is connected to the tilting frame 41. The hydraulic cylinder's telescopic motion drives the tilting shaft 43 to rotate, thereby achieving precise tilting of the aluminum ladle. During the pouring process, the mass of the aluminum ladle decreases continuously, and the hydraulic cylinder can always provide sufficient torque to prevent unstable tilting speed due to load fluctuations.

[0030] The vehicle 1 is equipped with drive wheels 11 at its base. Powered by a lithium battery, it can be moved to various aluminum casting furnaces via a remote control, enabling omnidirectional movement within the workshop. Warning lights and sensors are installed around the vehicle 1, providing audible and visual warnings during movement and monitoring the surrounding environment for automatic obstacle avoidance.

[0031] The support base 12 is provided with a set of support legs 13 at each of the four outer corners of the carrier 1. A lifting mechanism 2 is provided between the support base 12 and the carrier 1 to drive the support base 12 and the support legs 13 to move vertically relative to the carrier 1. When the lifting mechanism 2 controls the support base 12 to lift, the bottom of the support legs 13 is lifted above the drive wheel 11, the support legs 13 are separated from the ground, and the drive wheel 11 bears the load, and the carrier 1 is in a moving state. After the carrier 1 reaches the aluminum casting furnace, it is in a ladle-lifting state. The lifting mechanism 2 controls the support legs 13 to lower to the ground, and their bottoms are lower than the drive wheel 11, forming a rigid support structure of the column, preventing the carrier 1 from shaking during the tipping process.

[0032] Specifically, if Figure 4 As shown, the lifting mechanism 2 includes a lifting assembly, a lifting hydraulic cylinder 21, and a lifting inclined block 22. The lifting inclined block 22 is fixedly connected to the carrier 1, and the lifting inclined block 22 has an inclined guide surface. The fixed end of the lifting hydraulic cylinder 21 is rotatably connected to the carrier 1, and the driving end of the lifting hydraulic cylinder 21 is rotatably connected to the lifting assembly. The lifting assembly performs a swinging motion driven by the lifting hydraulic cylinder 21. The lower part of the lifting assembly contacts the lifting inclined block 22 and moves along the guide surface of the lifting inclined block 22 driven by the lifting hydraulic cylinder 21. The upper part of the lifting assembly contacts the bottom surface of the support seat 12, and drives the support seat 12 and the tilting aluminum injection mechanism 4 to perform vertical movement during the swinging process of the lifting hydraulic cylinder 21, so as to realize the switching of the carrier 1 between the moving state and the bag lifting state.

[0033] Specifically, the lifting assembly includes two sets of upper wheels 23 and lower wheels 24 disposed on the front and rear sides of the vehicle 1. The lower wheels 24 are in rolling contact with the guide surface, converting the linear thrust of the lifting hydraulic cylinder 21 into rotational motion; the upper wheels 23 are in rolling contact with the bottom of the support base 12, converting the rotational motion into vertical lifting motion of the support base 12. The upper wheels 23 and lower wheels 24 each have a wheel rim and are rotatably connected to a set of lifting beams 25. The middle portion of the lifting beams 25 is rotatably connected to the drive end of the lifting hydraulic cylinder 21. The lifting beams 25 serve as a rigid connecting body and can support the upper wheels 23 and lower wheels 24, integrating the two sets of upper wheels 23 and lower wheels 24 into a synchronous motion unit. The two sets of upper wheels 23 and lower wheels 24 move synchronously, preventing the support base 12 from tilting during the lifting process and having a certain anti-eccentric load capability.

[0034] like Figure 4As shown, the lower wheel 24 is located on the upper edge of the guide surface, the upper wheel 23 is pressed against the bottom of the support base 12, the support leg 13 is lifted off the ground, and the distance between the support leg 13 and the ground is approximately 50-100mm, so the vehicle 1 can move freely. The lower wheel 24 moves down along the guide surface until it reaches the position shown in FIG. Figure 1 In the lower edge position shown, the support base 12 moves downward along with the upper wheels 23, and the support legs 13 contact the ground. Furthermore, when the support legs 13 contact the ground, there is a clearance of approximately 10 mm between the upper wheels 23 and the bottom of the support base 12. The load on the support base 12 is no longer transferred to the vehicle 1 and the upper wheels 23. The weight of the vehicle is borne solely by the support legs 13, preventing deformation of the drive wheels 11 and upper wheels 23 due to the load.

[0035] This embodiment uses a hydraulic cylinder swing structure to control the up and down movement of the support seat 12. Compared with the straight-top linear drive component, the hydraulic cylinder is set horizontally, which can greatly reduce the stroke required by the drive component. At the same time, the horizontally set lifting beam 25 can convert the thrust of the hydraulic cylinder into a larger lifting torque.

[0036] Furthermore, the support legs 13 are connected to limit wheels 14 on the sides of the cart 1. The limit wheels 14 are in rolling contact with the sides of the cart 1, forming a hard limit for the cart 1, restricting lateral displacement of the cart 1. The cart 1 can only move vertically relative to the support legs 13. The rolling contact between the limit wheels 14 and the cart 1 can reduce frictional resistance generated during relative motion.

[0037] Furthermore, the support base 12 is also equipped with a movable trough mechanism 3 for directing the molten aluminum within the ladle. The movable trough mechanism 3 includes an inclined trough 31, which guides the flow of the molten aluminum through gravity. The trough 31 is movably connected to the support base 12. Extending the trough 31 expands the aluminum pouring space; retracting it reduces the space occupied by the trough 31. The interior of the trough 31 is lined with a high-temperature resistant lining. The poured aluminum is injected through the upper end of the trough 31, while the lower end extends into the aluminum casting furnace, reducing the impact of splashing. A dust collection fan 33 is installed at the molten aluminum inlet of the trough 31, which extracts air through negative pressure to reduce the generation of harmful powders during the pouring process. Furthermore, a dust hood 32 is installed at the molten aluminum inlet of the trough 31 to prevent the molten aluminum and harmful powders from leaking into the atmosphere.

[0038] like Figure 5As shown, in this embodiment, the movement of the guide trough 31 relative to the support base 12 is driven by a gear rack structure. A gear 34 is provided above the support base 12, and a rack 35 is installed at the bottom of the guide trough 31 along the direction of movement. The gear 34 is rotatably connected to the top of the support base 12 via a support frame 15. The gear 34 is driven by a motor to rotate, and the pinion structure drives the rack 35 to move horizontally, thereby controlling the sliding of the guide trough 31.

[0039] Furthermore, the bottom of the guide trough 31 is provided with a guide rail 36 extending in the translational direction. A guide wheel 37 is rotatably connected to the support frame 15. The guide wheel 37 engages the surface of the guide rail 36 in rolling contact, restricting the movement of the guide trough 31 during translation, restricting its telescopic movement relative to the support base 12 in a predetermined direction. This enhances the stability of the movement of the guide trough 31. The guide rail 36 is further configured as a slot-shaped structure, with the guide wheels 37 mounted within the slotted opening of the guide rail 36 and engaging the upper and lower slot edges of the guide rail 36 to further restrict its movement. In this embodiment, two sets of guide wheels 37 are provided, one on the left and right sides of the gear 34.

[0040] Furthermore, if Figure 6 As shown, a front support wheel 38 is provided at the bottom of the guide trough 31, facing away from the extension direction, specifically at the bottom of the guide rail 36. When the turning frame 41 is in an unturned state, the front support wheel 38 is in rolling contact with the surface of the turning frame 41 and translates along the surface of the turning frame 41, providing support for the movement of the guide trough 31, ensuring the movement trajectory of the guide trough 31 and preventing deviation of the guide trough 31 during telescopic movement. When the guide trough 31 is extended relative to the support seat 12, the front support wheel 38 disengages from the turning frame 41, allowing the turning frame 41 to freely tilt and flip the aluminum molten ladle.

[0041] Furthermore, if Figure 5 As shown, the support base 12 is provided with a rear support wheel 39 on one side extending along the guide trough 31. The rear support wheel 39 is arranged above the support base 12 via a rear wheel bracket. When the guide trough 31 is extended, the rear support wheel 39 rolls against the bottom of the guide trough 31, specifically the bottom of the guide rail 36. The rear support wheel 39 also limits the movement of the guide trough 31. At the same time, when pouring molten aluminum, the rear support wheel 39 can support the guide trough 31, ensuring stability during the pouring process.

[0042] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
