[0002] The diameter of the center tube is DN550mm~600mm. In the production of the center tube fittings, a centrifugal main engine is used to drive the tube mold to rotate, and it is poured by a pouring machine. After the tube fittings are formed, a tube pulling machine is needed to pull the tube fittings out of the tube mold. In view of this, a pouring and spraying equipment for a centrifugal pipe casting machine is disclosed in the patent document with application number 201921420867.7. The above-mentioned prior art cannot achieve quantitative addition of molten steel, and the ladle is a rotating ladle support and cannot achieve the transfer of the ladle. In the prior art, the chute is inserted into the tube mold and fixed in position during the casting process, and the molten steel flows out of the chute to the same position of the tube mold, resulting in uneven casting.

[0003] The pulled-out pipe fittings are placed on the transport trolley through the left and right pipe fitting mechanisms in the rocker-type pipe fitting weighing device of the centrifugal pipe casting machine disclosed in application No. 201921383577.X. The transport trolley in the prior art does not have a buffer structure. Therefore, when the pipe fittings roll onto the transport trolley, the impact on the pipe fittings is relatively large, which can easily cause deformation of the pipe fittings and affect product quality. At the same time, a hot mold centrifugal pipe casting machine protective cover assembly disclosed in application No. 201910807460.8 does not have the functions of removing steam and cooling.

[0008] Furthermore, the ladle body is located on the ladle conveying roller, or the ladle clamping shaft is clamped in the ladle clamping groove. The ladle conveying roller can be provided to realize the transfer of the ladle body containing molten steel, so that the ladle clamping shaft is clamped in the ladle clamping groove, and the ladle clamping shaft is clamped in the ladle clamping groove when pouring the molten steel.

[0058] Specifically, when processing pipe fittings, the centrifuge used for center pipe processing installs the sand core on the socket end of the pipe mold through the core loading crane E, casts it into the pipe mold through the pouring machine A, drives the pipe mold to rotate through the centrifugal main machine D, and forms pipe fittings in the pipe mold, pulls out the pipe fittings through the pipe pulling machine F, and places the pulled out pipe fittings on the pipe transport trolley B1 through the pipe connecting assembly B2, and transports the pipe fittings through the pipe transport trolley B1.

[0059] When the pouring machine A is working, the ladle body A211 filled with molten steel is transferred to the ladle conveying roller A218 by the molten steel transfer vehicle, and the ladle body A211 is transported to the ladle bracket A213 by the ladle conveying roller A218, so that the ladle clamping shaft A212 is clamped into the ladle clamping groove A214, so that the ladle body A211 is fixed to the ladle flipping bracket A217, and at the same time the ladle flipping cylinder A216 drives the ladle bracket A213 to flip along the bracket rotating shaft A215, so that the molten steel in the ladle body A211 flows into the flow ladle A22, and flows into the flow channel A23 through the flow hole on the flow ladle A22.
