Embodiment
Below in conjunction with accompanying drawing, self-centering formula Argon device connector of the present utility model is elaborated by specific embodiment.
Self-centering formula Argon device connector comprises bearing 1, supporting plate 2, spring 3, extension- type shelter 4,5, three-jaw centering unit 6, orienting sleeve 7, plug 8, spring 9, spring support 10 and argon gas metallic hose 11, dust exhausting hole 12, O RunddichtringO 13 and socket overcoat 14.
Bearing 1 has oval groove along buggy ladle infinite place direction, and socket 5 slides in oval groove under the guiding of three-jaw centering unit 6.
Plug 8 is installed on the ladle transport trolley, the manufacturing of whole employing stainless steel, and head is a dome-type.Plug 8 offers air inlet port, passes through for argon gas.
Extension-type shelter 4 adopts the stainless material manufacturing, comprises the three-decker that is sleeved on together, and internal layer can stretch in outer shield cap.
Adopt the argon gas metallic hose 11 of stainless steel manufacturing to adopt tube stub to be threaded with plug 8.
Socket 5 adopts the stainless steel manufacturing, and its inside is provided with air inlet port, and the cylindrical surface is processed in the bottom of air inlet port, and O RunddichtringO 13 is installed on its inwall, and socket 5 is processed into sphere with the plug contact surface, can closely cooperate the looping seal strip with plug.The upper end of socket 5 is arranged in the socket overcoat 14, and the upper end of socket 5 also is arranged with spring 3, and three-jaw centering unit 6 is around in the bottom of socket 5, the bottom of spring 3 and three-jaw centering unit 6 butts.
Orienting sleeve 7 adopts the stainless material manufacturings to form, and the upper end is inverted hydraucone shape, promptly its bore from top to bottom bore reduce gradually, the lower end is a cylindrical sleeve.Have dust exhausting hole 12 around the orienting sleeve 7, be used for dust discharge.
The lower end butt of plug 8 has spring 9, and spring 9 is arranged on the spring support 10, and plug 8 is pressed in the socket 5 under the effect of spring 9, prevents that argon gas from leaking.Can alleviate simultaneously the impact of socket 5, under the elastic force effect of spring, plug 8 and socket 5 be compressed, prevent that effectively argon gas from leaking.
The working process of self-centering formula Argon automatic coupler of the present utility model is as follows:
When the ladle handling was to the ladle transport trolley, along with the whereabouts of ladle, three-jaw centering unit 6 entered in the cylindrical sleeve of orienting sleeve 7 under bell-mouthed guiding on the orienting sleeve 7, drove socket 5 and slided in the oval groove on bearing 1 together.After bumping against orienting sleeve 7 bottoms, on the inwall of three-jaw centering unit 6 tensioners cylindrical sleeve in orienting sleeve 7, plug 8 slides in the socket 5 simultaneously.Under the effect of spring 9, plug 8 fits to closely with socket 5.Argon gas just can enter into by the pipeline on the ladle in the ladle bottom gas permeable brick, realizes being dynamically connected certainly of ladle bottom Argon device and ladle transport trolley.
In the external refining production process, the extension-type shelter 4 on the ladle covers on the orienting sleeve 7, prevents that effectively slag and dust from entering in the orienting sleeve 7 blocking pipeline.When slinging ladle, when plug 8 was extracted out in socket 5, when the argon gas switch still cut out fully, the argon gas that leaks out was discharged from dust exhausting hole 12, and socket 5 is played washing action.
In other embodiment, shield cap can be set to double-layer structure or the more multi-layered structure more than three layers.
