Description

A kind of blast furnace overhaul scaling platform
Technical field
The utility model relates to blast furnace overhaul, particularly relates to a kind of blast furnace overhaul platform.
Background technology
During the overhaul of smelter Iron Works, blast-furnace body has a large amount of cooling staves to need to install, the installation carrying out cooling stave just must set up a repairing platform device in State of Blast Furnace, utilize elevator or jack to carry out the lifting up and down of platform, maintainer just can carry out upkeep operation safely on this platform.But because each segmentation place internal diameter of blast furnace is different, the platform diameter set up is carrying out reducing or increasing along with the diameter change of blast furnace, and reduce platform diameter and just remove landing slab and framework secondary beam with cutting of cutting knife, increase platform diameter needs again to look for material again to weld.The shortcoming of this repairing platform device is apparent: 1) cycle is long, and 3 hours are generally wanted in the change of a platform diameter.2), cost is high.The often labor force of the secondary amount of having high input, consumes a large amount of steel and welding electrode and oxy-acetylene, returns cooling stave installation personnel simultaneously and causes the work holdup to a certain degree.
Summary of the invention
The utility model is intended to address the deficiencies of the prior art, and provides a kind of blast furnace overhaul scaling platform.The utility model can easily change platform diameter, saves time and cost, Be very effective on shortening main line duration and the minimizing labor force work holdup.
A kind of blast furnace overhaul scaling platform of the utility model, it comprises, one group of telescopic square tube, each telescopic square tube is star-shaped arrangement, and mid point is fixed on a plectane jointly, each telescopic square tube comprises the large square tube at middle part and outside little square tube, and little square tube one end is inserted in large square tube movably, the one side at the back of an angle steel is welded in the other end termination, square tube upper berth steel springboard.
Described a kind of blast furnace overhaul scaling platform, is provided with lacing wire between described large square tube.
Described a kind of blast furnace overhaul scaling platform, described large square tube length and blast furnace minimum diameter to be repaired coupling.
Described a kind of blast furnace overhaul scaling platform, the length=blast furnace maximum radius to be repaired-large square tube length/2+500mm of described little square tube.
Mainly according to drawing installing after cooling stave, in stove, minimum diameter is as the intermediate fixed portion (scaling platform minimum diameter) of scaling platform in the utility model the present invention, and blast furnace maximum inner diameter is as scaling platform maximum diameter.With channel-section steel, angle steel, steel plate and Checkered Steel Plate and steel springboard for material, by method well in advance in overhaul shop of welding, springboard in stove, lays colligation as required.During site operation, according to the size of State of Blast Furnace interior diameter, each flexible the moving back of scaling platform tapped out with sledgehammer, stationary platform ties up springboard, can construct.
The utility model greatly reduces the process time of lifting gantry.Because the flexible adjustment platform size of scaling platform only needs several minutes to complete, add to tear open and take a springboard needs about 20 minutes altogether, often adjust in putting up platform and once can save 2.5 hours, the installation of whole cooling stave at least adjusts platform size more than 10 times, Be very effective on shortening main line duration and the minimizing labor force work holdup.
Former stationary platform material usage is large, and waste is many, needs to cut weldering back and forth, and the material usage of scaling platform own is also little, without the need to reprocessing after making.Therefore obviously the cost of overhaul can be reduced.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described:
Fig. 1 is the utility model schematic diagram.
Embodiment
As shown in Figure 1, a kind of blast furnace overhaul scaling platform, it comprises, one group of telescopic square tube, each telescopic square tube is star-shaped arrangement, and mid point is fixed on a plectane 1 jointly, each telescopic square tube comprises the large square tube 2 at middle part and outside little square tube 3, in the outside diameter that large square tube is combined into and State of Blast Furnace minimum diameter close to but outline is a little bit smaller, little square tube is enclosed within large square tube can free shrink, and stretch out maximum after can also retain 500mm in large square tube, do lacing wire 4 with angle steel between large size square tube and be linked to be an integral platform framework.
Large size square tube plane completely spreads Checkered Steel Plate as steel springboard, Checkered Steel Plate is connected and fixed with the framework mode of welding.
At little square tube end socket downhand welding angle steel head 5, convenient can insert and can carry on a shoulder pole at cooling stave suitable for reading, can also prevent little square tube from all entering large square tube out bad simultaneously, flexible little square tube is helped to tie to make operation platform with steel springboard.
