Abstract
The utility model belongs to an automatic lance adjusting device for a steel-making oxygen lance in the oxygen blast device technical field. The utility model which comprises a lift trolley and a metal tube is characterized in that an adjusting plate is arranged on the lift trolley, the metal tube is connected with the adjusting plate and the oxygen lance body is fixed on the adjusting plate; the adjusting plate, the oxygen lance body and the metal tube are fixed into a whole body by a fixing unit; a hemispherical supporting point arranged at the gravity center of the whole body is acted on the trolley body and the whole body is fixed with the trolley body through a manual adjusting unit and a connecting unit. The utility model has the advantages that the oxygen lance can automatically adjust the difference of the axis of the lance body and the center of the tuyere by the adjusting plate under gravity; the manual adjustment can help realize the free rotation of the oxygen lance axis in 360 degrees of the converter tuyere plane; the lance adjusting time is shortened, therefore the production efficiency is improved.
Description
Technical field
The utility model belongs to steel-making oxygen blowing apparatus technical field, specifically a kind of automatic regulating lance device for steel making oxygen lance.
Background technology
The oxygen rifle is the visual plant of modern converter Oxygen Furnace Steel, and the oxygen rifle is fixed on the lift cart, links to each other with a strip metal oxygen pipe with the two strip metal water pipes that are fixed on lift cart, realizes making steel to Converter Oxigen Blowing moving up and down of riser guide by dolly.Existing oxygen lance lifting guide rail majority is a skeleton construction, the wheel of lift cart is at the riser guide internal rotation of framework, reason owing to working accuracy and wearing and tearing, add laying particular stress on of three strip metal flexible pipes, ubiquity oxygen rifle is fixed on the medullary ray of back oxygen rifle on the lift cart and there is certain deviation at the fire door center of converter, need manually align the oxygen rifle.At present, the diameter of domestic 300 tons of converter oxygen guns is φ 402, and the oxygen rifle is under the situation that feeds water coolant, and nearly 10 tons of oxygen rifle weight are transferred relatively difficulty, 2 hours rifle time of accent of overlapping to the medullary ray of so heavy rifle body and fire door medullary ray nearly.People's wage adjustment rifle has not only increased working strength of workers, and labour productivity is low, runs counter to modernized quick steel.
Summary of the invention
For addressing the above problem, the utility model provides a kind of novel oxygen rifle and the coupling device of lift cart, reaches the purpose of automatic regulating lance.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of automatic regulating lance device for steel making oxygen lance comprises lift cart and metallic hose, it is characterized in that: be provided with one and adjust plate on lift cart, metallic hose is connected with the adjustment plate, and the oxygen gun body is fixed on to be adjusted on the plate; Adjustment plate, oxygen gun body, metallic hose are fixed into an integral body by stationary installation, be provided with a hemisphere face point of suppon and act on the dolly car body on this whole center of gravity; Whole and dolly car body is fixed by artificial setting device and coupling device.
Compared with prior art, usefulness of the present utility model is:
The oxygen rifle can be adjusted the deviation at rifle body medullary ray and fire door center automatically by adjusting plate under the effect of gravity; Artificial adjustment can realize that oxygen rifle medullary ray rotates freely, and has shortened the accent rifle time, thereby has enhanced productivity in the 360 ° of scopes in converter mouth plane.
Description of drawings
Fig. 1 is the front view of automatic regulating lance device for steel making oxygen lance.
Among the figure, 1 adjusts plate, 2 metallic hoses, 3 oxygen gun bodies, 4 stationary installations, 5 point of suppon, 6 dolly car bodies, 7 setting devices, 8 coupling devices.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment:
A kind of automatic regulating lance device for steel making oxygen lance, comprise lift cart and metallic hose 2, it is characterized in that: on lift cart, be provided with one and adjust plate 1, metallic hose 2 is connected with adjustment plate 1, oxygen gun body 3 also is fixed on to be adjusted on the plate 1, make adjustment plate 1 by stationary installation 4, oxygen gun body 3, metallic hose 2 forms an integral body, hemisphere face point of suppon 5 of design acts on the dolly car body 6 on this whole center of gravity, by these point of suppon 5 integral body can be in the horizontal direction any adjustment angle, adjust the back and make whole fixing by artificial setting device 7 and coupling device 8 with dolly car body 6.
