System for adding stemming and replacing crooked chisel to multiple iron notches and working method

Abstract

The invention belongs to the technical field of blast furnace front casting house equipment, and particularly provides a system for adding stemming and replacing a crooked chisel to multiple iron notches and a working method. The system comprises a mechanical arm, and further comprises a positioning module and iron notch rails corresponding to the iron notches one to one, wherein a flat trolley isarranged on the iron notch rails, and the mechanical arm is arranged on the flat trolley; when the flat trolley receives an operation instruction, the mechanical arm is driven to move to the corresponding operation position along the iron notch rails according to positioning information of the positioning module; and the mechanical arm controls a stemming clamp at the tail end to grab the stemming to fill a clay gun or is connected with a crooked chisel clamp to replace the crooked chisel. According to the positioning information, the flat trolley drives the mechanical arm to move to the corresponding operation position along the iron notch rails, when the crooked chisel is not replaced, the crooked chisel clamp and the stemming clamp are separated, and when the crooked chisel is replaced, the crooked chisel clamp is combined to the stemming clamp, so that cost is saved, efficiency is improved, and meanwhile the frequency of replacing the clamp through the mechanical arm is reduced.

Description

technical field [0001] The invention belongs to the technical field of blast furnace front casting yard equipment, and particularly relates to a system and a working method which are also used for adding tapping mud and replacing iron brazing with multiple taps. Background technique [0002] The casting yard is located in a hot, dusty and labor-intensive work area. Each taphole of the blast furnace casting field is equipped with a mud gun and a taphole machine. The iron hole opening machine is used to open the iron hole through the rotary drilling and rapping of the iron drill, and release the molten iron smelted in the furnace through the iron hole. The mud cannon is used to block the taphole by pressing the taphole clay into the taphole after the taphole has been tapped, so that the blast furnace can perform normal smelting operations. [0003] The iron drill used by the iron hole opening machine is a vulnerable part, and the used drill rod needs to be replaced after eac...

Problems solved by technology

However, these devices often have the following disadvantages: they occupy too many casthouse platforms, and each taphole needs to add two sets of devices, which is not convenient for the operation and maintenance of taphole machines, mud guns and other devices; more equipment leads to high cost once, The production and maintenance are complicated; two sets of equipment need to be added, and it is difficult to be suitable for the situation where the mud gun and the tap hole machine are arranged on the same side; the automatic mud adding device on the market needs a set in order to disperse the piles of mud for automatic use. Dispersing and conveying device for gun mud takes up a lot of space and costs a lot
