Abstract
The utility model discloses a kind of blast furnace cooling stave maintenance hoisting structure, comprise cooling stave body, in the upper inside wall of cooling stave body, interval is installed with two bolts, and the outboard end of two bolts is being threaded connection respectively a sleeve pipe, and suspension hook is connecting respectively two sleeve pipes by wireline.The utility model can substitute the hanger of cooling stave, reaches the effect of safety, quick, convenient lifting blast furnace cooling stave, and this device also can reach the effect of locating cooling stave simultaneously.
Description
Technical field
The utility model belongs to blast furnace ironmaking field, relates to a kind of blast furnace cooling stave maintenance hoisting structure.
Background technology
Blast furnace cooling stave is the important water-cooled part of blast furnace lining, is arranged on the position such as shaft, furnace bosh, bosh, cupola well of blast furnace.Cooling wall energy prevents that furnace shell is heated and burns redly effectively, and blast furnace lining brick is ablated rear main by slag crust protection cooling stave itself, and maintains the safety in production of blast furnace.Therefore, cooling stave is the important guarantee that blast furnace safety is produced.Blast furnace has arrived the generation stove labour later stage, and cooling wall breakage is serious, and the chance of repairing or limiting the production in must utilizing is carried out blowing out and changed cooling stave, to ensure safety in production.Because of new cooling stave, when dispatching from the factory, at top, upper end, all cast hanger is installed, so that lifting is used when mounted, after installation in position, just cut off, old cooling stave is when removing, and without hanger, hanging just becomes the difficult problem while removing cooling stave.If cooling stave need to reuse simultaneously, from a blast furnace, remove and be mounted to another blast furnace, also there is without hanger the problem of difficult hanging.
Summary of the invention
The utility model provides a kind of blast furnace cooling stave maintenance hoisting structure, substitutes the hanger of cooling stave, reaches the effect of safety, quick, convenient lifting blast furnace cooling stave, and this device also can reach the effect of locating cooling stave simultaneously.
The utility model solves the technical scheme that its technical problem adopts: a kind of blast furnace cooling stave maintenance hoisting structure, comprise cooling stave body, in the upper inside wall of cooling stave body, interval is installed with two bolts, the outboard end of two bolts is being threaded connection respectively a sleeve pipe, and suspension hook is connecting respectively two sleeve pipes by wireline.
When the utility model is used, reject the rust joint material in complete cooling stave surrounding parietal suture, start screw block, in stove, hold out against cooling stave, until loosening.Now install sleeve pipe, install for two side by side simultaneously, from the furnace shell perforate of standing bolt, penetrate precession standing bolt.Use lifting appliance to bind sleeve pipe, after continue to start screw block, in stove, hold out against cooling stave, until cooling stave departs from the fixing of furnace shell.When cooling stave is installed, in advance by interim hanger precession, use lifting appliance to bind sleeve pipe, lifting puts in place, interim hanger furnace shell perforate is penetrated, and interim hanger is held with cucurbit, cooling stave in place in outside, reach the effect of safety, quick, convenient lifting blast furnace cooling stave, this device also can reach the effect of locating cooling stave simultaneously.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is main TV structure schematic diagram of the present utility model.
Embodiment
A kind of blast furnace cooling stave maintenance hoisting structure, as shown in Figure 1, comprise cooling stave body 4, in the upper inside wall of cooling stave body 4, interval is installed with two bolts 3, the outboard end of two bolts 3 is being threaded connection respectively a sleeve pipe 6, and suspension hook 1 is connecting respectively two sleeve pipes 6 by wireline 5.
Claims (1)
1. a blast furnace cooling stave overhauls hoisting structure, comprise cooling stave body, it is characterized in that: in the upper inside wall of cooling stave body, interval is installed with two bolts, the outboard end of two bolts is being threaded connection respectively a sleeve pipe, and suspension hook is connecting respectively two sleeve pipes by wireline.
