Abstract
The invention discloses an auxiliary device for installing an air inlet small sleeve, which comprises a walking mechanism and a lever, wherein two ends of the lever are respectively provided with a handle operating part and an air inlet small sleeve insertion part, the middle part of the lever is arranged on the walking mechanism, and the distance between the operating part and the walking mechanism is more than that between the insertion part and the walking mechanism. When a blast furnace is blown down and the air inlet small sleeve is replaced, the air inlet small sleeve can be stably sent to the installing position, thus the labor intensity of workers can be greatly lightened, the time of replacing an air inlet of the blast furnace can be shortened, the working efficiency is increased, and the blowing down rate of the blast furnace can be lowered.
Description
Technical field
The present invention relates to the setting tool of the little cover of ironmaking tuyere of blast furnace, is a kind of supplementary unit that blast furnace tuyere small sleeve is installed.
Background technology
The blast furnace that metallurgy industry is used to smelt iron needs the air port air blast in stove through the blast furnace air inlet system.The air port of blast furnace air inlet system is made up of 3 layers of air port cover usually, and one deck of wherein pressing close to most in the stove is claimed " tuyere small sleeve ".Because the large blast furnace inlet number is more, and blast furnace tuyere small sleeve belongs to consumable accessory, often often replacing.Tuyere small sleeve is the workpiece that adopts the refractory materials sintering to form, and AW is also not little, generally about 200kg, relies on artificial muscle power carrying fully, and it is bigger to implement difficulty, and causes the work damage easily.In the production scene; Usually adopt the auxiliary carrying of electric hoist, when tuyere small sleeve is about to arrive the installation position, need tuyere small sleeve be filled in the air port at that time; Electric hoisting equipment such as electric hoist can't use; Use jack speed is too slow and can't " tuyere small sleeve " be sent to the installation site, therefore, also needs manual work to carry at this position.To the deficiency of prior art, the someone has invented a kind of disassemblerassembler that utilizes the tuyere small sleeve that fork truck carries and install, and announces to some extent that in Chinese patent CN 2685346Y this equipment can substitute the installation and removal that manpower carries out tuyere small sleeve.But this equipment also has certain shortcoming, must carry out work by fork truck, and what use is hydraulic coupling in the process of work, and the size of dynamics and precision are difficult to grasp, cause the breakage of blast furnace air inlet mouth and tuyere small sleeve easily.
Summary of the invention
The object of the present invention is to provide a kind of supplementary unit that tuyere small sleeve is installed, a kind of simple small instruments and tools cheaply is provided, be used for assisting tuyere small sleeve is installed, alleviate labor strength and increase work efficiency.
The present invention solves the technical scheme that its technical problem takes: a kind of supplementary unit that tuyere small sleeve is installed; It is characterized in that; Comprise travel mechanism and lever; Be respectively at the two ends of said lever lever operated with the tuyere small sleeve Plug Division, the middle part of said lever is installed on the travel mechanism, and operating portion apart from the distance of travel mechanism greater than the distance of Plug Division apart from travel mechanism.
Described Plug Division is to form through a circular block plate is installed at an end of lever, and said block plate is apart from the distance of the lever end length less than tuyere small sleeve.
Described travel mechanism comprises axletree, wheel and support, and wheel is installed on the axletree, and support is installed in the middle part of axletree, and vehicle frame directly links to each other with lever, and this is a kind of mode of travel mechanism.
The invention has the beneficial effects as follows: when blast furnace staying is changed tuyere small sleeve, use this device; Can send to the installation site to tuyere small sleeve steadily; Can alleviate labor strength significantly, can shorten blast furnace and change the air port time, increase work efficiency; Can reduce the blast furnace staying rate, improve the business economic benefit.
Description of drawings
Fig. 1 is a stereographic map of the present invention;
Fig. 2 is user mode figure of the present invention;
Among the figure: 11 axletrees, 12 wheels, 13 supports, 2 levers, 21 operating portions, 22 Plug Divisions, 23 block plates, 3 tuyere small sleeves.
Embodiment
Like Fig. 1, shown in Figure 2, a kind of supplementary unit that tuyere small sleeve is installed comprises travel mechanism and lever.
Travel mechanism comprises axletree 11, wheel 12 and support 13, and wheel 12 is installed on the axletree, and support is an inverted-V-shaped, and support is installed in the middle part of axletree, and vehicle frame directly links to each other with lever, forms a wheeled travel mechanism.Use for convenient, can design a cover locking mechanism on the wheel of travel mechanism wherein, can easily travel mechanism locking be placed on the position of any needs.
Be respectively lever operated 21 and tuyere small sleeve Plug Division 22 at the two ends of lever 2; The middle part of lever 2 is installed on the support 13 of travel mechanism; The Plug Division is to form through a circular block plate 23 is installed at an end of lever; Block plate is apart from the distance of the lever end length less than tuyere small sleeve, can be easily to the tuyere small sleeve carrying of pegging graft.Greater than the distance of Plug Division apart from travel mechanism, a people operates separately operating portion apart from the distance of travel mechanism, and according to lever principle, a people can carry 200 kilograms tuyere small sleeve easily.
Method of use does, at first the air port of tuyere small sleeve 3 is inserted in 22 places, Plug Division of lever, and operator's operation handle arm moves to the place, air port of blast furnace with tuyere small sleeve then, behind the aligning slowly tuyere small sleeve is filled in the air port, installs to get final product, and is very easy to use.
Except that the described technical characterictic of specification sheets, be the known technology of those skilled in the art.
Claims (3)
1. supplementary unit that tuyere small sleeve is installed; It is characterized in that; Comprise travel mechanism and lever; Be respectively at the two ends of said lever lever operated with the tuyere small sleeve Plug Division, the middle part of said lever is installed on the travel mechanism, and operating portion apart from the distance of travel mechanism greater than the distance of Plug Division apart from travel mechanism.
2. a kind of supplementary unit that tuyere small sleeve is installed according to claim 1 is characterized in that, described Plug Division is to form through a circular block plate is installed at an end of lever, and said block plate is apart from the distance of the lever end length less than tuyere small sleeve.
3. a kind of supplementary unit that tuyere small sleeve is installed according to claim 1 and 2 is characterized in that described travel mechanism comprises axletree, wheel and support, and wheel is installed on the axletree, and support is installed in the middle part of axletree, and vehicle frame directly links to each other with lever.
