Abstract
The utility model relates to a steelmaking blast furnace, in particular to an oxygen lance of the steelmaking blast furnace. The utility model discloses an oxygen lance lifting appliance, which comprises two steel plates arranged in parallel, wherein the two ends of the two steel plates are connected by an upper hinge pin and a lower hinge pin; the upper hinge pin and the two steel plates are connected into a whole; the lower hinge pin is connected to the oxygen lance by a chain; one end of the lower hinge pin is provided with a plug; the other end of the lower hinge pin is provided with a clamping pin. By using the oxygen lance lifting appliance, the problems that a lifting steel rope is frequently replaced and the potential safety hazard is high in the prior art are solved, the cost is saved, and the overhaul efficiency is improved.
Description
Technical field
The utility model relates to steel-making blast furnace, relates in particular to the oxygen rifle of steel-making blast furnace.
Background technology
Oxygen rifle is as one of steel mill steelmaking equipment visual plant, working environment very severe due to oxygen rifle, for a long time in hot environment, so changing, oxygen rifle becomes an indispensable part in steelmaking process, and oxygen lance is arranged on again the highest order of steel-making factory building, oxygen rifle is changed must be by driving and steel wire rope handling above high dummy section, equipment, and maintainer also will hang steel wire rope in the air at height.In through one period of repair time, we find to hang that to rob steel rope abrasion serious, and fracture of wire phenomenon just appears in week age steel wire rope, if change not in time or do not have similar steel wire rope (φ 30) to change, has very large potential safety hazard in changing rifle process.
Summary of the invention
The utility model is intended to address the aforementioned drawbacks, and a kind of oxygen rifle suspender is provided.The utility model has solved and has hung the problems such as steel rope replacing is frequent, potential safety hazard is large of robbing in the past.And saved cost, improved overhaul efficiency.
For addressing the above problem, a kind of oxygen rifle of the utility model suspender, it comprises two steel plates that be arranged in parallel, two steel plate two ends are connected with bottom bearing pin with top bearing pin respectively, top bearing pin and two steel plates are connected, bottom bearing pin connects oxygen rifle by chain, and its one end is provided with plug, and other end punching arranges bayonet lock.
Described oxygen rifle suspender, described two steel plates and inside, upper pin shaft connection place are equipped with triangle gusset.
The utility model bottom bearing pin connects in suspender with chain, is convenient to bearing pin and uses, and steel wire rope remains on suspender central authorities when lifting.The utility model avoids that steel rope replacing is frequent, potential safety hazard is little, has saved cost, has improved overhaul efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described:
Fig. 1 is the utility model schematic diagram.
The specific embodiment
As shown in Figure 1, a kind of oxygen rifle suspender, it comprises two steel plates that be arranged in parallel 1, two steel plate two ends are connected with bottom bearing pin 3 with top bearing pin 2 respectively, and top bearing pin and two steel plates are connected, and bottom bearing pin connects oxygen rifle by chain, its one end is provided with plug, and other end punching arranges bayonet lock.Described two steel plates and inside, upper pin shaft connection place are equipped with triangle gusset 4.
Claims (2)
1. an oxygen rifle suspender, is characterized in that, it comprises two steel plates that be arranged in parallel, two steel plate two ends are connected with bottom bearing pin with top bearing pin respectively, and top bearing pin and two steel plates are connected, and bottom bearing pin connects oxygen rifle by chain, its one end is provided with plug, and other end punching arranges bayonet lock.
2. oxygen rifle suspender according to claim 1, is characterized in that, described two steel plates and inside, upper pin shaft connection place are equipped with triangle gusset.
