Abstract
The present invention provides an EAF hanger for furnace body, including a hanging body, showing ''H'' shaped radial case, the top of the hanger main beam out-of-center is set with a ring; the lower symmetrical four ends of the hanger are set with a lower ring respectively, the lower ring interior is connected with a balancing wheel by hinge pin, one ends of the balancing wheel and the rope are connected. When the invention is used on the top of the EAF, the travelling crane descends, when pushing the rope to liftinglug to contact with the protecting cover, the travelling crane ascends, when the furnace falls off furnace platform locating stud, transporting to the appointed repair position. By the same token, new EAF body is transported to exchange, the hanging transportation of the EAF body is realized. The advantages of the invention has a simple structure, convenient operating use, better synchronicity, lifting centre of gravity of the hanger and the centre of gravity of the body are superposition, and also has a better wholly mechanical property, furthest avoiding the extruding of the rope and the body water pipeline when hanging the body. Further, the invention also reduces labor intensity and shortens operation time.
Description
Technical field
The present invention relates to a kind of suspender, especially a kind of EAF body of heater suspender.
Background technology
EAF (arc furnace) stove and accessory has advantages such as smelting special steel, developing new product variety, thereby is widely used.And the EAF stove causes the loss of refractory material owing to the aggressive action of molten steel, slag in smelting process, on average just needs to change a body of heater less than 300 stoves.
Two ways that driving lifts are adopted in the replacing of present domestic high capacity EAF body of heater mostly, its method is the two ends that hang sling respectively with two drivings, according to the non-equilibrium state of body of heater, adjust the balance of body of heater with the lifting altitude difference of two drivings in the handling body of heater process.The shortcoming of its method is that poor synchronization, duty cycle are long.The method that the producer that also has adopts two steel wire cable pockets to hang is changed body of heater, sees Fig. 1, the shortcoming steel wire cable discontinuity equalization of this method and the balance of body of heater, body of heater difficulty in place.Not only steel wire cable and upper of furnace body can produce and hit pressure, and working strength of workers is big, and duty cycle is long.
Summary of the invention
The present invention is for overcoming above-mentioned the deficiencies in the prior art, and a kind of simple in structure, easy for operation, EAF body of heater suspender that synchronism is good is provided.
The objective of the invention is to adopt following technical proposals to realize: a kind of EAF body of heater suspender, comprise and hang body, the described body that hangs is for being the radial casing of " H " type, and the off-center place, girder top of hanging body is provided with upper lift ring; Four ends of hanging body bottom symmetry are respectively equipped with lower lift ring, are connected with balance wheel by bearing pin in the lower lift ring, and balance wheel is connected with an end of rope.
The axial line of described lower lift ring with hang the body axial line one 45～47 ° β angle arranged.
The other end of described rope is provided with anti-sharp object and squeezes the protecting sleeve of hindering, and it not only plays the effect of protection steel wire cable, and brings convenience and safety to operation.
Described body, upper lift ring and the lower lift ring assembly welding of hanging becomes an integral body, and is respectively equipped with floor on it, strengthened single-piece rigidity.
As the present invention during with EAF (arc furnace) the body of heater top arrive to need changed, driving descends, after a end that rope has a protecting jacket arrives the hanger position of body of heater, after rope pushed hanger and protecting jacket contacts, driving is risen, and after body of heater breaks away from the table locating dowel pin, transports to the repair location of appointment.Then arrive new EAF (arc furnace) body of heater top and descend, after a end that rope has a protecting jacket arrives the hanger position of body of heater, after rope pushed hanger and protecting jacket contacts by driving, driving is risen, be transported to the table top, after body of heater is aimed at the table locating dowel pin, fall to placing the tram.By aforesaid operations, the present invention can realize the handling of EAF (arc furnace) body of heater.Because the suspender of this body of heater is the radial box of " H " type, therefore when the handling body of heater, suspender can not contact with the cooling water pipe of body of heater, can avoid the squeeze and destroy to the cooling water pipe of body of heater.
Advantage of the present invention be simple in structure, easy for operation, synchronism is good, crane lifting center of gravity overlaps with the body of heater center of gravity, the whole mechanical property of suspender is good, can avoid the extruding of rope itself and body of heater water pipe when the handling body of heater to greatest extent.And reduce labour intensity and shorten production time.
Description of drawings
Fig. 1 is a steel wire cable embodiment scheme drawing;
Fig. 2 is a structural representation of the present invention;
Fig. 3 is the embodiments of the invention scheme drawing;
Wherein 1. hang body, 2. upper lift ring, 3. lower lift ring, 4. rope, 5. balance wheel, 6. bearing pin, 7. protecting jacket, 8. hanger, 9. body of heater.
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
Among Fig. 2, Fig. 3, hang body 1 for being the radial casing of " H " type.The off-center place, girder top of hanging body 1 is provided with upper lift ring 2; Four ends of hanging body 1 bottom symmetry are respectively equipped with lower lift ring 3; be connected with balance wheel 5 by bearing pin 6 in the lower lift ring 3; balance wheel 5 is connected with an end of rope 4; the other end of rope 4 is provided with anti-sharp object and squeezes the protecting sleeve 7 of hindering; it not only plays the effect of protection steel wire cable 4, and brings convenience and safety to operation.
The axial line of lower lift ring 3 has one 45～47 ° β angle with the axial line that hangs body 1.
Hang body, upper lift ring and lower lift ring assembly welding and become an integral body, and be respectively equipped with floor on it, strengthened single-piece rigidity.
On technology, use explanation below with reference to Fig. 3 for the present invention:
When the present invention needs EAF (arc furnace) body of heater 1 top of replacing with arrival, driving descends, after a end that rope 4 has a protecting jacket 7 arrives hanger 8 positions of body of heater 9, after rope 4 pushed hanger 8 and protecting jacket 7 contacts, driving is risen, after body of heater 9 breaks away from the table locating dowel pin, transport to the repair location of appointment.Then arriving new EAF (arc furnace) body of heater 1 top by driving descends, after a end that rope 4 has a protecting jacket 7 arrives hanger 8 positions of body of heater 9, after rope 4 pushed hanger 8 and protecting jacket 7 contacts, driving is risen, be transported to the table top, after body of heater is aimed at the table locating dowel pin, fall to placing the tram.By aforesaid operations, the present invention can realize the handling of EAF (arc furnace) body of heater 9.Because the suspender 1 of this body of heater 9 is the radial box of " H " type, therefore when handling body of heater 9, suspender 1 can not contact with the cooling water pipe of body of heater 9, can avoid the squeeze and destroy to the cooling water pipe of body of heater 9.
