Problems solved by technology

This method will greatly increase the downtime of the electric furnace and affect the economic benefits of the enterprise
Another method is to use manual spray guns to directly repair one by one after the electric furnace is shut down. This method not only increases the risk of gunning workers, but also has potential safety hazards, high labor intensity, and low gunning efficiency. The repair quality is poor, and some dead corners and furnace bottom cannot be repaired, which affects the improvement of the furnace life of the electric furnace

Embodiment Construction

[0029] The present invention will be further described below in conjunction with accompanying drawing.

[0030] As shown in Figure 1, the electric furnace automatic gunning machine of the present invention is made up of a main rotary mechanism, a lifting mechanism, a telescopic arm mechanism, a spray gun rotary device, a spray gun 24 and a support frame 32.

[0031] a. The main rotary mechanism is composed of a large rotary table 4, a base 2, a column 11 and a main rotary drive mechanism. The column 11 is fixed on the large rotary table 4, and the large rotary table 4 and the main rotary drive mechanism are installed on the base 2. The main rotary The driving mechanism can drive the column 11 to rotate in situ;

[0032] b. The lifting mechanism is composed of a slider 8, a slideway 14 and a lifting drive mechanism. The slideway 14 is longitudinally fixed on the column 11, the slider 8 is set on the column 11, and is slidably connected with the slideway 14. The lifting drive me...

Abstract

An automatic spray repairing machine of electric furnace is prepared as forming vertical column form of lifting mechanism by sliding block, slide-way and lifting-driving unit; forming telescopic arm mechanism by horizontal arm, telescopic arm and driving unit of telescopic arm; forming rotation mechanism by motor, speed reduction gear and bearing gear; connecting spray gun arm to telescopic arm, setting spray gun with nozzle at bottom end of spray gun arm and fixing top of support frame on horizontal arm and its bottom on bottom end of sliding block.

Description

technical field [0001] The invention belongs to the technical field of electric furnace wall gunning, in particular to an electric furnace automatic gunning machine. Background technique [0002] At present, when the furnace wall of the refractory material of the electric furnace is partially damaged, so that the electric furnace cannot continue to work, one method is to stop the furnace first, and then repair it after the temperature of the furnace has dropped. This method will greatly increase the downtime of the electric furnace and affect the economic benefits of the enterprise. Another method is to use manual spray guns to directly repair one by one after the electric furnace is shut down. This method not only increases the risk of gunning workers, but also has potential safety hazards, high labor intensity, and low gunning efficiency. The quality of repair is poor, and some dead corners and furnace bottom cannot be repaired, which affects the improvement of the servic...
