Description
Technical field
The utility model belongs to the improvement of ladle argon-blown syndeton, particularly a kind of ladle argon-blown draw bail of exempting from the manpower dismounting.
Background technology
The ladle of steelworks splendid attire molten steel; needs because of processing treatment; need to be blown into protective gas from ladle bottom---argon gas; invar wraps in different preparatory stage or the different stations produced, and needs handling back and forth, and the Argon draw bail is generally metallic hose and connects; therefore need manually nearby to install; but personnel safety in molten steel boiling, splash or the serious bag accident of wearing serious threat, and the also frequent scaling loss of the flexible pipe of Argon need be changed, and maintenance cost and workload are bigger.
The utility model content
The purpose of this utility model is to provide a kind of ladle argon-blown draw bail of exempting from the manpower dismounting, and it is simple in structure, is easy to manufacture, not only can avoid scaling loss effectively, long service life, and need not artificial participation and can finish the argon gas transportation work, safe and convenient to use.
The purpose of this utility model is achieved in that a kind of ladle argon-blown draw bail of exempting from the manpower dismounting, comprise upper pedestal and lower base, the intracardiac vertical gas distribution channel that is being provided with in the upper pedestal, the bottom center of upper pedestal has a pit connection section, the inlet pipe of upper pedestal and ladle bottom links together, lower base is installed on the tapping car, in the centre hole of lower base bottom the lower sub pipe that links to each other with pneumatic tube is being set, has the induction trunk that is connected with gas distribution channel in the upper pedestal in the lower sub pipe, the upper end of lower sub pipe constitutes the epirelief connection section that matches with said pit connection section, form air-tight fit between epirelief connection section and the pit connection section, have the spring deck on the lower sub pipe outer peripheral edges, suit return spring on the lower sub pipe between spring deck and the lower base bottom surface.
The utility model Argon draw bail is divided upper and lower pedestal two portions, the upper pedestal that connects with the ladle bottom joint is with the ladle handling, lower base is installed on tapping car or the refining steel hired car, forms air-tight fit between the epirelief connection section of upper and lower pedestal and the pit connection section.Owing on the lower sub pipe in the lower base return spring is installed, when upper pedestal was sitting on the lower sub pipe, return spring was compressed and produces the sealing pressure, avoids between the upper and lower pedestal gas leakage taking place like this.
The utility model is simple in structure, is easy to manufacture, and not only can avoid scaling loss effectively, long service life, and need not the artificial installation nearby that participates in, can finish being tightly connected between the upper and lower pedestal, finish the argon gas transportation work, effectively stopped the personnel safety accident, safe and convenient to use.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is that master of the present utility model looks cross-sectional view.
Embodiment
A kind of ladle argon-blown draw bail of exempting from the manpower dismounting as shown in drawings, comprises upper pedestal 2 and lower base 7, and lower base 7 is the box body shape of opened top.Lower base 7 can also only be made of one flat plate.The intracardiac vertical gas distribution channel that is being provided with in the upper pedestal 2, the bottom center of upper pedestal 2 has a pit connection section, and upper pedestal 2 links together with the inlet pipe of ladle bottom 1.
Lower base 7 is installed on the tapping car 8, the lower sub pipe 5 that links to each other with pneumatic tube is being set in the centre hole of lower base 7 bottoms, the external diameter of lower sub pipe 5 bottoms makes lower sub pipe 5 can move downward a segment distance when being subjected to downward reactive force less than the aperture in lower base 7 bottom centre holes.
Has the induction trunk that is connected with gas distribution channel in the upper pedestal 2 in the lower sub pipe 5, the upper end of lower sub pipe 5 constitutes the epirelief connection section that matches with said pit connection section, form air-tight fit between epirelief connection section and the pit connection section, have the spring deck on lower sub pipe 5 outer peripheral edges, suit return spring 6 on the lower sub pipe 5 between spring deck and lower base 7 bottom surfaces.Said return spring 6 is dish spring or garter-type spring.
Said spring deck is for to be provided with annular shoulder block or bearing pin on lower sub pipe 5 outer walls.
Said air-tight fit is for to be provided with sealing-ring 3 in pit connection section and the contacted annular contact surface of epirelief connection section.
One grommet type seals 4 is being set on the bottom surface of upper pedestal 2, and this grommet type seals 4 contacts with the annular shoulder block end face of lower sub pipe 5, thus further reinforced seal effect.
When the utility model uses, upper pedestal 2 is sitting on the lower sub pipe 5, realize being tightly connected by said epirelief connection section and pit connection section between the two, the pipe of lower sub simultaneously 5 bears the gravity that upper pedestal 2 applies, under the effect of return spring 6, make lower sub pipe 5 upwards hold out against upper pedestal 2, easily realize the butt joint of gas distribution channel.
Said pit connection section is semisphere, and said epirelief connection section is semisphere.
