Description
Technical field
This utility model relates to a kind of Blast Furnace Air Mouth Set Relieving Device, a kind of modified model sliding hammer for quick-replaceable blast-furnace tuyere.
Background technology
At present, burning out air port therefrom specific purpose tool of pull-out in cylinder when damping down old when sliding hammer is to change air port, the sliding hammer structure of existing use is excessively simple, in use existing defects.During as transported sliding hammer in air port, because air port is in inside furnace bosh, there are substantial amounts of coke, the skull that the most also part bits are formed in front end, and the eave tile of the bigger sliding hammer of resistance is difficult to enter, only throw into sledgehammer, the eave tile contact surface of drag hook is big, and coke and skull resistance are the biggest, beats also difficulty, operation is wasted a lot of time, and increases the labor intensity of workman.
Furthermore, after the drag hook of sliding hammer enters inlet front end, owing to there being a large amount of coke in stove, and need the air port changed because of generation substantial amounts of steam, the gas burner of leaking, workman is difficult to judge the eave tile of drag hook the most upward, only eave tile the most just can catch on air port, it is sometimes necessary to attempts just can determine that the position of drag hook back and forth, wastes time and energy.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of modified model sliding hammer for quick-replaceable blast-furnace tuyere, described sliding hammer makes workman drag hook can be delivered to inside air port smoothly when changing air port, and workman accurately judges sliding hammer eave tile upward in air port external enwergy, save and change the air port time, alleviate the labor intensity of workman.
In order to solve above-mentioned technical problem, the technical solution of the utility model is achieved in that
A kind of modified model sliding hammer for quick-replaceable blast-furnace tuyere, described sliding hammer includes drag hook, pull bar, left plug, hammer body, right plug, baseline rod；End, pull bar one end is provided with drag hook, and the eave tile of drag hook is the most upward；Being fixedly installed left and right plug staggered relatively on pull bar, on the pull bar between left and right plug, movable sleeve is provided with hammer body；The pull bar other end is vertically and fixedly arranged in the middle part of baseline rod and baseline rod horizontal positioned.
Further, described left and right plug is respectively hollow disc shape, is pulled along sliding hammer when sending drag hook in air port, and drag hook just can enter air port the most easily；
Further, described left plug is positioned in the middle part of pull bar, left and right plug spacing 2m；
Further, described hammer body is hollow circular cylinder；
Further, described baseline rod uses steel pipe manufacturing to form, and its specification is internal diameter 33.3mm × length 200mm, and baseline rod uses steel pipe length unsuitable long, it has not been convenient to puts and lifts sliding hammer.
This utility model beneficial effect compared to existing technology:
This utility model simple in construction, easy to use, economical and practical, save the replacing air port time, greatly alleviate the labor intensity of workman.Specifically:
1, this utility model makes workman drag hook can be delivered to inside air port smoothly when changing air port, and workman accurately judges sliding hammer eave tile upward in air port external enwergy, has saved the replacing air port time, alleviates the labor intensity of workman.
2, utilize this utility model change blast-furnace tuyere need not large-area cleaning and burn air port contact surface with oxygen, save the cost such as oxygen, oxygen lance, as long as same air port just can install, save the set-up time.
3, through existing blast furnace test of many times, 35 minutes air port the shortest used times are changed with this device, the longest 50 minutes, and conveniently, safely, effectively, change air port time-consuming at about 1 hour, blast furnace air-supply in 1 hour in advance just can make blast furnace fecund ferrum more than 200 ton, need promptly to repair wind at about 5 times because of air port breakage every year, replacing can save the time of 5 hours, produce 200 tons of pig iron on an hourly basis to calculate, within 5 hours, it is exactly 1000 tons, in terms of 2930 yuan per ton of pig iron price, effect 3,000,000 yuan can be created every year.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
As shown in Figure 1 and Figure 2, a kind of modified model sliding hammer for quick-replaceable blast-furnace tuyere, described sliding hammer includes drag hook 1, pull bar 2, left plug 3, hammer body 4, right plug 5, baseline rod 6；
End, pull bar 2 one end is provided with drag hook 1, and the eave tile of drag hook 1 is the most upward；
Being fixedly installed left and right plug 3,5 staggered relatively on pull bar 2, on the pull bar 2 between left and right plug 3,5, movable sleeve is provided with hammer body 4, and described hammer body 4 is hollow circular cylinder；
Described left and right plug 3,5 is respectively hollow disc shape, is pulled along sliding hammer when sending drag hook 1 in air port, and drag hook 1 just can enter air port the most easily；
Described left plug 3 is positioned in the middle part of pull bar 2, left and right plug 3,5 spacing 2m；
Pull bar 2 other end is vertically and fixedly arranged in the middle part of baseline rod 6 and baseline rod 6 horizontal positioned, described baseline rod 6 uses steel pipe manufacturing to form, its specification is internal diameter 33.3mm × length 200mm, and baseline rod 6 uses steel pipe length unsuitable long, it has not been convenient to puts and lifts sliding hammer.
This utility model application in changing blast-furnace tuyere operating process:
(1) preparation tool, is ready to shorten the damping down time before damping down
(1) during blast furnace checking, changing the instrument used by air port such as: drag hook, hit thick stick, size by rake, hydrous taphole loam, length drill rod, sledgehammer, etc. be ready to.
