[0020] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation.

[0021] Example 1, in conjunction with Appendix Figures 1 to 3 An automatic tilting device for molten aluminum ladles includes a base 1, a tilting frame 2, and a locking device 3. One side of the tilting frame 2 is hinged to the base 1. A tilting telescopic cylinder 4 for driving the tilting frame 2 to tilt is installed between the other side of the tilting frame 2 and the base 1. When in use, the molten aluminum ladle is placed on top of the tilting frame 2. When molten aluminum needs to be poured, the tilting telescopic cylinder 4 is controlled to extend and drive the tilting frame 2 to tilt, thereby tilting the molten aluminum ladle and pouring out the molten aluminum.

[0022] The two corners of the tilting frame 2 are hinged to the base 1 and are equipped with positioning baffles 5. The two corners of the other side of the tilting frame 2 are equipped with locking devices 3. That is, when the aluminum ladle is tilted, the two positioning baffles 5 and the two locking devices 3 hold the aluminum ladle together, thereby fixing the aluminum ladle on the tilting frame 2 and preventing the aluminum ladle from rolling off accidentally during the tilting process, which is highly safe.

[0023] The locking device 3 includes a top plate 3-1 for pressing down on the aluminum ladle. A push-telescopic cylinder 3-2 for driving the top plate 3-1 away from the positioning baffle 5 and the tilting frame 2 is installed between the top plate 3-1 and the positioning baffle 5. In use, the push-telescopic cylinder 3-2 is first shortened, and the push-telescopic cylinder 3-2 drives the top plate 3-1 to move backward, making more space for the aluminum ladle. The aluminum ladle can then be hoisted onto the top of the tilting frame 2 using existing ground aluminum ladle mobile equipment, which can effectively reduce the difficulty of hoisting operation. Then, the push-telescopic cylinder 3-2 is extended, and the push-telescopic cylinder 3-2 pushes the top plate 3-1, and the top plate 3-1 pushes the aluminum ladle until the aluminum ladle contacts the two positioning baffles 5. The push-telescopic cylinder 3-2 is then in the pushing state, which can firmly hold the aluminum ladle and fix it on the tilting frame 2.

[0024] To further improve the stability and reliability of the locking device 3, as shown in the attached... Figure 2 As shown, the locking device 3 also includes a fixed seat 3-3 that is fastened to the flipping frame 2. The fixed seat 3-3 is movably inserted with two guide posts 3-4, one end of which is fastened to the top plate 3-1. That is, the fixed seat 3-3 is provided with two guide holes that correspond to the guide posts 3-4 at intervals. The two guide posts 3-4 are movably inserted into the two guide holes respectively, which can effectively prevent the top plate 3-1 from accidentally jamming during movement. The cylinder body of the push telescopic cylinder 3-2 is fastened to the fixed seat 3-3.

[0025] Example 2, in conjunction with Appendix Figure 1 An automatic aluminum ladle tilting device differs from Embodiment 1 in that, based on Embodiment 1, each of the four corners of the tilting frame 2 is provided with a connecting column 6, and each of the two corners of one side of the base 1 is provided with a supporting column 7. The tops of the two connecting columns 6 on the side of the tilting frame 2 with the positioning baffle 5 are respectively hinged to the tops of the two supporting columns 7 via hinge shafts. That is, when the aluminum is poured, the tilting frame 2 drives the bottom of the aluminum ladle to tilt upwards, and the opening of the aluminum ladle is close to the hinge shaft. Therefore, the downward tilting stroke of the opening of the aluminum ladle is small, which can effectively improve the stability of aluminum casting. The tops of the two connecting columns 6 on the other side of the tilting frame 2 are hinged with a tilting telescopic cylinder 4. The other end of the tilting telescopic cylinder 4 is correspondingly hinged to the base 1. The tilting telescopic cylinder 4 is correspondingly connected to the tilting frame 2 via the connecting column 6, which can effectively reduce the installation tilt angle of the tilting telescopic cylinder 4 and reduce the bending moment borne by the tilting telescopic cylinder 4.

[0026] Example 3, in conjunction with the appendix Figure 4 An automatic aluminum ladle tipping device, based on Embodiment 1 or 2, wherein the bottom of the base 1 is rotatably connected to the vehicle chassis 9 via a rotary support 8, enabling the aluminum ladle to be transported via the vehicle chassis 9. The rotary support 8 drives the base 1 to rotate, thereby allowing selection of the tipping direction of the aluminum ladle. The vehicle chassis 9 can be a car chassis, a tracked chassis, or a rail-mounted chassis. Hydraulic outriggers 10 are provided at each of the four corners of the vehicle chassis 9, allowing the hydraulic outriggers 10 to extend and land before tipping the aluminum ladle. The hydraulic outriggers 10 support the vehicle chassis 9, improving its stability and ensuring safety during the tipping process.
