Embodiment 1

[0029] Such as Figure 1-4 As shown, it is a tap hole machine that can detect the depth of the tap hole, including a driving device 1, a traveling trolley 4, and a hydraulic rock drill 5 arranged on the traveling trolley 4. The hydraulic rock drill 5 is connected with a drilling device, and the drilling device consists of The drill pipe sleeve 6, drill pipe 7, and drill bit 8 installed on the hydraulic rock drill 5 successively from left to right; The driving device 1 includes a transmission shaft 31 , a transmission chain 32 , an end cover 33 and a base 34 , and one end of the transmission shaft 31 drives the traveling trolley 4 to run through the transmission chain 32 .

[0030] A detection system is also provided on the taphole machine, the detection system is installed on the end cover 33 of the driving device 1 through the flange 12, and the bearing 13 is installed in the flange 12; the detection system includes a tapered joint 11, a flexible coupling Device 14, encoder ...

Embodiment 2

[0034] Such as Figure 5As shown, when the iron hole needs to be opened, the trolley 4 drives the drill pipe 7 to drill forward. At this time, the drill bit 8 of the drill pipe 7 moves from point A to point B. Since this distance is an empty stroke, the speed is very fast. , the speed is 70mm / s, when it touches the gun mud B and starts to drill and punch the gun mud, the speed is 9-10mm / s, when drilling to point C, the drill bit needs to be replaced due to the damage of the drill bit, so the drill pipe can only be withdrawn, record at this time The first distance is BC. When the drill bit is replaced, it starts drilling again. The speed from the beginning to point D is an empty stroke, so the speed is faster than 70mm / s, so this distance is not recorded. When drilling from point D When reaching point E, the speed is 9-10mm / s. When drilling to point E, the drill bit needs to be replaced due to the damage of the drill bit, so the drill pipe can only be withdrawn. At this time, r...

Abstract

The invention discloses a method for detecting the iron notch depth by using an iron notch drill, and relates to the technical field of blast furnace iron-making. Specifically, a starting point or an ending point of the travel of a trolley are determined and recorded according to the traveling speed of a punching and drilling device; the timing starting point of each section of travelling stroke in the starting and middle processes is the starting point of trolley deceleration, and the ending point is the time point when the drill bit is replaced and the drill rod is withdrawn; and the timing point of the last travelling stroke is the starting point of deceleration of the trolley, and the ending point is the starting point of acceleration of the trolley. According to the method, the defect of inaccurate iron notch depth detection in the prior art is overcome, the empty drilling time of the travelling trolley is removed, the recorded drilling time of each section is completely the stemming drilling time of the drill rod, the starting point and the ending point of each stroke are accurately set according to the speed change of the trolley, and the accuracy of the finally calculated iron notch depth is improved.

Description

technical field [0001] The invention relates to the technical field of blast furnace ironmaking, in particular to a method for detecting the depth of a taphole by using a tapping hole machine. Background technique [0002] As an important part of the blast furnace tapping, the furnace front equipment plays a pivotal role in the safe and stable operation of the blast furnace. The blast furnace tapping machine and hydraulic mud gun are powered by a set of corresponding hydraulic stations. The taphole machine is a commonly used equipment in ironworks. Its function is to open the blast furnace taphole to realize modern blast furnace smelting. Components: The structure of the tapping machine is mainly composed of a rotary part and a drilling part. The drilling part is mainly composed of propulsion and punching parts, and the rotary part sends it from the parking position to the working position. After opening the iron hole, it is quickly sent back to the parking position. The r...
