When the stirring head is not replaced, the replacing vehicle has the function of blowing air to remove slag. The utilization rate of the vehicle is effectively improved, and the difficulty that the space for independently arranging the air blowing and slag removing facilities is small is solved.

The utility model comprises a stirring head support A1, a stirring head support B2, a safety guardrail 3, an air blowing slag removing device 4, a replacing vehicle frame 5, a replacing vehicle transmission 6, a chain transmission 41, a lifting rail 42, a swing cylinder 43 and an air blowing slag removing gun 44; the replacing vehicle transmission 6 is connected with the replacing vehicle frame 5 by a transmission chain.

A stirring head support 1A and a stirring head support 2B are arranged at one end of the upper part of the vehicle body, a safety guardrail 3 is arranged at the other end of the vehicle body, an air blowing and slag removing gun device 4 is arranged at the other end of the vehicle body, a motor chain transmission device 41, a lifting rail 42, a swing cylinder 43 and an air blowing and slag removing gun 44 are arranged on the air blowing and slag removing device 4, and the air blowing and slag removing gun 44 can move up and down in the lifting rail 42.

When the replacing vehicle is in a non-working state, the stirring head is not arranged on the stirring head bracket, a motor speed reducer gear of the blowing slag removing device drives a chain to lift the blowing slag removing gun to a high position, the electro-hydraulic oscillating cylinder retracts, and the lifting track is swung to a vertical position. See the non-working state diagram.

When the operation of stirring head needs to be changed, at first with new stirring head hoist and mount on one of them arbitrary position of two stirring head supports of frame mesa, will change the car and drive KR processing position, with the old stirring head center of one of them vacancy alignment in two stirring head supports of workshop mesa, catch the back with old stirring head, start and change the car and make new stirring head and KR processing position coincidence, connect new stirring head on KR agitating unit. Then the replacing vehicle with the old stirring head is driven out of the processing position, and the KR can continue to operate production. Completing a quick change period of the stirring head.

Because the durable material of the stirring head has a long service life, the stirring head is generally replaced once in 10-15 days. The replacing vehicle is mainly used for finishing the work of blowing and removing slag at ordinary times.

When the gas blowing and slag removing work state is adopted, the replacing vehicle is firstly started to a gas blowing and slag removing position, then the swinging cylinder stretches out to swing the lifting track to an angle suitable for slag blowing, the swinging cylinder stops, the motor drives the chain to blow gas and remove slag under the slag gun to be close to the molten iron liquid level, the gas blowing valve is opened, gas sprayed from the gas blowing and removing slag gun head is used for removing the molten iron surface iron slag to the ladle opening, and the slag is removed by the slag removing machine. The swing angle and the parking position can be adjusted in the slag removing process, so that slag removing operation at different molten iron surface positions is realized.

The technical effects of the utility model are that:

two stirring head storage supports are arranged on one replacing vehicle, the traditional single stirring position arrangement scheme is replaced, the problems of long occupied time and high labor intensity of replacing the stirring heads are solved, and the production stop time occupied by replacing is reduced; the position of the replacing vehicle is fully utilized, the replacing vehicle is designed in a multifunctional mode, the using function of the replacing vehicle is increased by adding the device for blowing and removing the slag, the using value of equipment is improved, and the problem that the space for independently arranging a facility for blowing and removing the slag is small is solved.
