then, starting a longitudinal moving motor (110) and driving a longitudinal moving screw rod (111) to rotate, driving an electric drill (41) to move towards a furnace shell (15), and drilling a target position;
after the drilling is finished, the mechanical arm drives the operation platform (1) to move away from the furnace shell (15) until the gas collecting ring (8) is restored to an initial state, then the transverse moving mechanism (12) is started and drives the transverse moving sliding table (2) to move horizontally and rightwards along the first sliding rail (9), after the drilling position is reached, the longitudinal moving motor (110) reverses and drives the electric drill (41) to move in a direction away from the furnace shell (15), the feeding platform (50) can be synchronously driven to move towards the drilling position by virtue of the action of the swinging rod (60) and the strip hole (64) positioned on the outer side until the grouting short pipe is conveyed to the drilling position, the grouting short pipe is welded and fixed by using matched welding equipment, after the welding is finished, the mechanical arm drives the operation platform (1) to move away from the furnace shell (15) until the gas collecting ring (8) is restored to the initial state, and the sleeve (51) is separated from the grouting short pipe at the moment, and the next drilling operation is prepared;
after welding, a control ball valve is arranged at the grouting short pipe, a single-cylinder pump is used for pressing the hard refractory material into the furnace through the grouting short pipe, when the hard refractory material is pressed into the furnace, furnace burden in the furnace plays a role of a baffle, and after the hard pressed material enters the furnace, the hard pressed material is spread between a furnace shell (15) and the furnace burden and is adhered to the furnace shell, so that the effect of lining building in the furnace is achieved.
