Abstract
The utility model relates to a safety lifting lug for lifting a blast furnace downcomer, which is characterized in that a hanging plate of the safety lifting lug is a rectangular steel plate of which a bottom surface is an inclined plane; the bottom surface is at an included angle of 41 degrees with the horizontal plane; the top surface of the hanging plate is in arc transition with both the left and right lateral surfaces of the hanging plate; the bottom of the hanging plate is provided with a 45-degree double-sided welding groove; the upper part of the hanging plate is provided with a center lifting hole; and the distance between the center of the lifting hole and the top surface of the hanging plate is equal to those between the center of the lifting hole and the left and right lateral surfaces of the hanging plate. In the using process of the safety lifting lug, the safety lifting lugs are respectively welded at lifting points of the downcomer, the downcomer is lifted by a crane and a lifting steel wire rope and the safety lifting lug is safe and reliable.
Description
Technical field
The utility model belongs to hanger, especially relates to a kind of blast furnace downtake lifting hanger.
Background technology
In the installation work of metallurgy industry blast furnace system, the difficulty that is lifted in the blast furnace system installation work of downtake is larger, such as 1080m
3The downtake of blast furnace is from weighing more than 90 ton, will form with horizontal surface the angle of 41.3758o during lifting aloft, the hanger of downtake lifting adopts rectangular steel plate perforate usually, in order to satisfy the force request of hanger, usually can only strengthen width and the thickness of hanger, often waste steel plate.
Summary of the invention
The purpose of this utility model is to propose a kind of blast furnace downtake lifting to use safe hanger, and is not only simple and reasonable, easy to make, and safe and reliable, also saves steel.
The purpose of this utility model is achieved like this: a kind of blast furnace downtake lifts with safe hanger (being called for short safe hanger), the boatswain chair that it is characterized in that this safe hanger is that the bottom surface is the rectangular steel plates on inclined-plane, and this bottom surface is horizontal by the angle of 41 o, the end face of this boatswain chair is with left, be arc transition between the right flank, two-sided bevel for welding is spent with 45 in bottom at this boatswain chair, offer the center hole for hoist on the top of this boatswain chair, and end face and the left side of the width between centers boatswain chair of this hole for hoist, right flank is all equidistant, this boatswain chair can with thickness of slab be the 45mm material be No. 45 steel plates with gas cutting tool at the construction field (site) gas cutting form, the length of this boatswain chair can be 425mm, the wide 300mm that can be, end face and the left side of the width between centers boatswain chair of hole for hoist, the vertical distance of right flank all can be 150mm, and the diameter of this hole for hoist can be Ф 95mm.
During use, this safe hanger is welded respectively on the lifting point of downtake, uses crane and lifting steel rope lifting downtake, safety is reliable again.
Safe hanger is used in the blast furnace downtake lifting that the utility model proposes, and is not only simple and reasonable, easy to make, and safe and reliable, also saved steel.
The blast furnace downtake lifting that now in conjunction with the accompanying drawings and embodiments the utility model is proposed is described further with safe hanger.
Description of drawings
To be the blast furnace downtake lifting that proposes of the utility model look scheme drawing with the master of safe hanger to Fig. 1.
Fig. 2 is that the blast furnace downtake lifting that the utility model proposes is looked scheme drawing with the left side of safe hanger.
Fig. 3 is the blast furnace downtake lifting that proposes of the utility model with the use scheme drawing of safe hanger.
Among Fig. 1-Fig. 3: 1, end face 2, left surface 3, right flank 4, hole for hoist 5, downtake 6, lifting steel rope.
The specific embodiment
Can find out from Fig. 1-Fig. 3: a kind of blast furnace downtake lifts with safe hanger (being called for short safe hanger), it is characterized in that: the boatswain chair of this safe hanger is that the bottom surface is the rectangular steel plates on inclined-plane, and this bottom surface is horizontal by the angle of 41 o, the end face 1 of this boatswain chair is with left, right flank 2, be arc transition between 3, two-sided bevel for welding is spent with 45 in bottom at this boatswain chair, offer center hole for hoist 4 on the top of this boatswain chair, and the end face 1 of the width between centers boatswain chair of this hole for hoist 4 and a left side, right flank 2,3 is all equidistant, this boatswain chair can with thickness of slab be the 45mm material be No. 45 steel plates with gas cutting tool at the construction field (site) gas cutting form, the length of this boatswain chair can be 425mm, the wide 300mm that can be, the end face 1 of the width between centers boatswain chair of hole for hoist 4 and a left side, right flank 2,3 vertical distance all can be 150mm, and the diameter of this hole for hoist 4 can be 95mm.
During use, this safe hanger is welded respectively on the lifting point of downtake 5, uses crane and lifting steel rope 6 lifting downtakes 5, not only safety but also reliable.
