s1, a butting rod (3) is in contact with the ground in a natural state, an auxiliary support is started for a casting ladle body (1), when the casting ladle body (1) is filled with metal liquid from a melting furnace and starts to move, an electric telescopic rod (5) is started through a control device of the casting ladle body (1) to lift the casting ladle body, a roller ball (4) can move freely due to the fact that the limitation of a pressed piece (6) is lost, the butting rod (3) does not obstruct the movement of the casting ladle body (1), the electric telescopic rod (5) is started after the casting ladle body (1) stops to drive the pressed piece (6) to descend, the roller ball (4) is pressed by the pressed piece (6), the casting ladle body (1) is effectively prevented from swinging irregularly due to inertia, and the stability during casting is improved;

s2, after pouring is started, the protection piece (2) can effectively prevent splashed sparks from falling on the body of a worker, an effective protection effect is achieved, in order to prevent strong light of metal liquid from stabbing eyes of the worker, the worker pulls up the eye protection plate (14) to protect eyes before the pouring is started, the exhaust fan (7) is started in the pouring process, toxic gas generated in the pouring process enters from the lower port of the U-shaped channel (2012) under the suction effect of the exhaust fan (7), and is exhausted outwards through the exhaust fan (7) after being filtered and purified by the gas filter screen (8), the flowing speed of air is accelerated, and the situation that the worker inhales the toxic gas is effectively avoided;

s3, in the process that the casting ladle body (1) moves, the distance sensor (16) monitors people on a moving line in real time, and when the people on the line is too close to the casting ladle body (1), the distance sensor (16) starts the alarm spotlight (17) to illuminate the high-temperature-resistant glass plate (202) and trigger the alarm, so that the function of prompting and early warning is started.
