Abstract
The utility model relates to converter, relates in particular to converter flue welding set.Weld a hanging ladder for converter flue, it is placed in converter mobile section by converter oxygen gun mouth, and it comprises: a base, and it is made by a channel-section steel; A cat ladder, it is uprightly placed on base, and root both sides are with gusset; Two horizontal ladders, they lay respectively at cat ladder both sides, and it is connected to cat ladder middle part away from cat ladder end by chain.The utility model can be accelerated welding speed, reduces welding cost, improves security.
Description
Technical field
The utility model relates to converter, relates in particular to converter flue welding set.
Background technology
Smelter steelwork converter flue is at the certain all after dates of production run, and the phenomenon that there will be breakage to leak at the water coolant endless tube of flue, need to carry out repair welding to flue water coolant endless tube, guarantees the normal operation of producing.Because converter flue is in converter mouth top; mobile section flue height is generally not less than 7m; if during welding mobile flue higher position; need to expend a large amount of manually setting up scaffolding or set up cat ladder, scaffolding or the access ladder construction time used of still setting up is long, generally needs 4 hours to 5 hours; cost is high; need to consume a large amount of manually, and while setting up and removing scaffolding or cat ladder, workmen's safety does not have reliable sfgd..
Summary of the invention
The utility model is intended to overcome the defect of prior art, and a kind of hanging ladder that welds converter flue is provided.The utility model can be accelerated welding speed, reduces welding cost, improves security.
In order to solve the problems of the technologies described above, a kind of hanging ladder that welds converter flue, it is placed in converter mobile section by converter oxygen gun mouth, and it comprises:
A base, it is made by a channel-section steel;
A cat ladder, it is uprightly placed on base, and root both sides are with gusset;
Two horizontal ladders, they lay respectively at cat ladder both sides, and it is connected to cat ladder middle part away from cat ladder end by chain.
The hanging ladder of described welding converter flue, described horizontal ladder is more than or equal to 2000mm at the tie point of cat ladder to cat ladder top distance.
The utility model is according to the size of diameter and height and oxygen muzzle diameter and the height of converter flue, the steel plate of steel pipe, channel-section steel and 10mm of take is material, by the method for welding, make in advance a kind of easy hanging ladder, converter stops production when flue is welded, utilize the time of flue draining, by the hanging ladder of making in advance, utilize oxygen rifle from oxygen muzzle, to put into flue inside across overhead traveling crane, and hanging ladder is fixed on oxygen muzzle, select safe and reliable position to draw and establish safety rope.Workmen enters flue from oxygen muzzle and constructs.After construction, with driving, can very soon special-purpose ladder hoisting gear be hung in flue, next shutdown maintenance can also reuse.Compared with prior art there is following remarkable advantage:
1), greatly reduced labor force's input, by number 9 people that originally constructed, be reduced to 3 people's constructions.
2), significantly reduced workman's labour intensity.During due to former welding flue, need to set up scaffolding or cat ladder, construction danger coefficient is high, and construction is used after instrument of the present invention, can utilize overhead traveling crane directly the hanging ladder of making to be put into flue and construct, the workload of having avoided setting up and removing scaffolding.
3), obviously reduced the cost of overhaul.When welding flue is used instrument of the present invention, the construction of having avoided setting up scaffolding or cat ladder, has shortened the time of construction greatly, thereby has significantly significantly reduced the cost of Construction and Maintenance.
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 hanging ladder that welds converter flue, it is placed in converter mobile section by converter oxygen gun mouth, and it comprises:
A base 1, it is made by a channel-section steel;
A cat ladder 2, it is uprightly placed on base, and root both sides are with gusset 5;
Two horizontal ladders 3,4, they lay respectively at cat ladder both sides, and it is connected to cat ladder middle part away from cat ladder end by chain 6.
The hanging ladder of described welding converter flue, the tie point of described horizontal ladder on cat ladder is more than or equal to 2000mm to cat ladder top distance.
Claims (2)
1. weld a hanging ladder for converter flue, it is placed in converter mobile section by converter oxygen gun mouth, it is characterized in that, it comprises:
