Abstract
The utility model proposes a kind of guider for converter movable hood, the device includes guide pipe and casing, guide pipe is installed on the lifting lug of movable gas hood vertically, casing shoe passes through the through hole opened up on movable gas hood upper platform, and it is connected with upper platform, guide pipe aligns inside and outside sheathed setting with cannula center, and casing inner diameter, which is more than, is oriented to pipe outside diameter.The utility model is simple in structure, can improve stability of the movable gas hood in normal work, reduces petticoat pipe rocking under lifting and other operating modes, avoids having a negative impact.
Description
Technical field
The utility model belongs to the technical field of Converter Residual Heat Boiler movable gas hood, more particularly to one kind is used for converter movable
The guider of petticoat pipe.
Background technology
Movable gas hood is installed on directly over converter, is the important component of carburetion system waste heat boiler.When converter iron making
, it is necessary to lifting skirt cover when water plus steel scrap；After above procedure is completed, usually require to reduce petticoat pipe before oxygen furnace steel.Carry
Cover with drop cover is completed by special lifting device, is present in each smelting cycle of pneumatic steelmaking in theory.Lifting dress
Four lifting lugs that petticoat pipe is usually connected by lifting rope or hydraulic stem are put, due to the disequilibrium between suspension centre everywhere, normal
The fluctuation of medium can cause certain rock in lifting process and in production process in petticoat pipe.In initial smelting period plus steel scrap,
After scrap steel trough once encounters petticoat pipe, rock especially violent.Petticoat pipe caused by above various reasons is rocked for production process
In security and stability and petticoat pipe service life in itself adversely affect.
Domestic petticoat pipe between tedge, down-comer by flexible apparatus with being usually connected, the lifting displacement of movable gas hood
Absorbed by flexible apparatus.Flexible apparatus is periodically rushed due to being frequently necessary to act and bearing caused by internal fluid pressure change
Hit, its service life is generally very limited, and by taking metal hose as an example, the general Only Six Months of its normal service life was to 1 year.
The service life rocked undoubtedly to flexible apparatus of petticoat pipe is unfavorable.
The content of the invention
The technical problem to be solved by the utility model is to for above-mentioned problem, there is provided one kind is used for converter and lives
The guider of dynamic petticoat pipe, it is intended to improve stability of the movable gas hood in normal work, reduce as far as possible petticoat pipe in lifting and
Rocking under other operating modes, and then reduce some adverse effects caused by petticoat pipe rocks.
Technical solution is used by the utility model solves above-mentioned technical problem：A kind of leading for converter movable hood
To device, it is characterised in that including guide pipe and casing, the guide pipe is installed on the lifting lug of movable gas hood vertically, described
Casing shoe passes through the through hole opened up on movable gas hood upper platform, and is connected with upper platform, guide pipe and cannula center pair
Just inside and outside sheathed setting, casing inner diameter, which is more than, is oriented to pipe outside diameter.
By such scheme, described sleeve pipe top is blind end, and by blind plate sealing, the first connection method is arranged below casing
Orchid, connecting flange are connected with upper platform by bolt.
By such scheme, the guide pipe bottom is connected by the second connecting flange with lifting lug.
By such scheme, the stroke of the guide pipe is less than the length of casing.
By such scheme, the gap between the guide pipe and casing is 3~8mm.
By such scheme, the nominal diameter of the guide pipe and casing is all higher than 100mm.
By such scheme, gusset is equipped between first connecting flange and casing, second connecting flange is with being oriented to
Gusset is equipped between pipe.
The beneficial effects of the utility model are：A kind of guider for converter movable hood, reduction activity cigarette are provided
The shaking amplitude of cover in the operating condition, improves the stability of petticoat pipe in operation, helps to extend petticoat pipe and tedge, decline
It is the service life of flexible connection between pipe, simple in structure, it is of low cost, it is convenient for installation and maintenance, extend the service life of movable gas hood.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model one embodiment.
Wherein：1. guide pipe, 2. casings, 3. lifting lugs, 4. upper platforms, 5. first connecting flanges, 6. second connecting flanges,
7. gusset, 8. blind plates.
Embodiment
To more fully understand the utility model, with reference to the accompanying drawings and examples the utility model is made further to retouch
State.
As shown in Figure 1, a kind of guider for converter movable hood, including guide pipe 1 and casing 2, guide pipe erects
Straight to install on the lifting lug 3 of movable gas hood, casing shoe passes through the through hole opened up on movable gas hood upper platform 4, and and upper strata
Platform is connected, and guide pipe aligns inside and outside sheathed setting with cannula center, and casing inner diameter, which is more than, is oriented to pipe outside diameter, guide pipe and casing
Between gap be 3~8mm, so both can guarantee that guide pipe axially lifting freely, can also prevent that the displacement of its radial direction is excessive,
Particularly when petticoat pipe double swerve, since gap is smaller, the excessive radial displacement of guide pipe is limited, so that having reached prevents
Petticoat pipe excessively rocks, and keeps the purpose of its stability.
Cannula tip is blind end, is sealed by blind plate 8, prevents debris from falling into, and the first connecting flange is arranged below casing
5, connecting flange is connected with upper platform by bolt, and guide pipe bottom is connected by the second connection method, 6 with lifting lug.First connects
Gusset 7 is equipped between acting flange and casing, gusset is equipped between the second connecting flange and guide pipe.
The stroke of guide pipe is less than the length of casing, and when the lifting of petticoat pipe, guide pipe moves up and down in casing all the time,
It ensure that its normal working performance.When petticoat pipe lifted to peak when, as in Fig. 1 dotted line represent guide pipe physical location,
It can be seen that still there is certain gap between guide pipe top and blind plate and between the second connecting flange and casing shoe；When skirt cover
When bottoming out, guide pipe upper end still sleeve overcoat, guarantee does not depart between the two.
During petticoat pipe rocks, guide pipe and casing will usually bear larger impact to limit petticoat pipe displacement, because
This guide pipe and casing usually select more than DN100 thick walled steel tubes, i.e. the nominal diameter of guide pipe and casing is all higher than 100mm.
