[0002] Aluminum casting cleaning vehicles, as key auxiliary equipment for core equipment such as smelting furnaces, holding furnaces, and mixing furnaces in medium and large aluminum plants, are primarily responsible for removing sediment from the bottom of liquid aluminum metal and scum from the surface, thereby improving the quality of aluminum ingots. Currently available aluminum casting cleaning vehicles in China are mostly equipped with tracked chassis, but this type of chassis has high energy consumption and high manufacturing costs. Furthermore, its operating speed is limited, and power consumption during operation and steering is significant. Parts wear rapidly, and the vehicle is prone to damage to the working environment and road surface. Therefore, the development of a lighter and more energy-efficient cleaning vehicle chassis is particularly urgent. Utility Model Content

[0026] Example 1. A slag scraper wheel chassis, the structure of which is referenced to Figures 1 to 4 , including a slewing bearing 1, which is arranged at the center of the top surface of the side beam frame 2. The side beam frame 2 includes a front axle 3 and a rear axle 4. The front axle 3 and the rear axle 4 are U-shaped, with the open ends of the front axle 3 and the rear axle 4 facing each other and the rear axle 4 inserted into the inner side of the front axle 3. The front axle 3 is a driving axle and driving wheels 5 are arranged on both sides of the closed end of the front axle 3. The rear axle 4 is a steering axle and driven wheels 6 are rotatably hinged on both sides of the closed end of the rear axle 4. The steering function of the wheeled chassis is achieved by rotatably hinged the driven wheels 6 on both sides of the closed end of the rear axle 4. Compared with the crawler walking chassis, the mechanical structure of this scraper wheeled chassis is less complex, the dead weight is lower, and the moving speed is increased when the same power system is used.

[0027] Two crossbeams 7 are installed inside the rear axle 4, with a slewing bearing 1 mounted on each crossbeam. Two support rods 8 are installed outside each of these crossbeams 7. One end of each support rod 8 connects to the center of the outer side of the crossbeam 7, while the other ends of each support rod 8 connect to the two sides of the closed ends of the front axle 3 and rear axle 4, respectively. The support rods 8 form a triangular support structure within the closed ends of the front axle 3 and rear axle 4. The provision of crossbeams 7 and support rods 8 improves the overall structural strength and rigidity.

[0028] A steering cylinder 9 is located at the center of the rear axle and is connected to the driven wheels 6 via a steering shaft. The drive wheels 5 are connected to the front axle 3 via a hydraulic motor. The steering cylinder 9 and the steering shaft coordinate to achieve steering of the scraper wheel chassis. Furthermore, by using the hydraulic motor as the power source for the drive wheels 5, it can be integrated with the steering cylinder 9 into the same hydraulic management system, making operation easier for the operator.

[0029] The rear axle 4 and the front axle 3 are connected by welding.

[0030] Example 2. The structure of this example is the same as that of Example 1, with the only difference being that the end of the front axle 3 close to the driven wheel 6 is provided with an inclined surface, and the angle of the inclined surface matches the rotation angle of the driven wheel 6. Based on the diameter of the driven wheel 6 and the range of the rotational articulation, and without affecting the rotation range of the driven wheel 6, the length of the front axle 3 is ensured to be the longest, and therefore an inclined surface is cut out at the end of the front axle 3 close to the driven wheel 6, and the sum of the cutting angle of the inclined surface and the rotation angle of the driven wheel 6 is 90°. By providing an inclined surface at the end of the front axle 3 close to the driven wheel 6, a larger turning space is provided for the driven wheel 6, thereby reducing the turning radius of the present slag skimmer wheel chassis.

[0031] Obviously, the above description is only a partial embodiment of the present invention, and not all embodiments. The above embodiments are not intended to limit the present invention. For those skilled in the art, various modifications and variations of the present invention are possible. Any combination, modification, equivalent replacement, improvement, and other embodiments that can be made by those of ordinary skill in the art within the spirit and principles of the present invention shall be within the scope of protection of the present invention.
