Description
Technical field
This utility model relates to a kind of quick-changing mechanism, particularly relates to a kind of quick-changing mechanism preventing continuous casting intermediate inlet from stopping, belongs to continuous casting tundish apparatus technical field.
Background technology
The tundish immersed nozzle mechanism that Mei Gang uses, the mouth of a river is changed the most online because of the erosion of molten steel, it is ensured that molten steel enters in crystallizer from middle packet stream continuously, it is achieved produce greatly continuity.And tundish is after being poured, the hole employing blind plate at the mouth of a river thoroughly blocks remaining molten steel and slag in ensureing tundish and does not flows out.The replacing at the mouth of a river and the closure rate request of blind plate are the fastest.Mei Gang middle water containing opening mechanism is fixed on tundish, has enough to meet the need maintenance with tundish, and the oil cylinder quick-changing mechanism of driving is suspended on when not producing on middle hired car, when tundish is installed on middle hired car, and quick-changing mechanism is installed on gate mechanism again.
At present, owing to quick-changing mechanism holddown spring easily damages, during use, gib head disengages automatically, and mechanism can not reliably fix, and cylinder piston rod stretches out deviation outlet replacing guide rail, causes fast sprue-replacing failure to break and water cutout.
For a long time, the problems referred to above cannot solve all the time at all.Therefore, above-mentioned technical problem is solved in the urgent need to a kind of new technical scheme.
Utility model content
This utility model is just for technical problem present in prior art, a kind of quick-changing mechanism preventing continuous casting intermediate inlet from stopping is provided, this technical scheme overall construction design is reasonable, ingenious, it is suitable for field requirement, convenient and swift reliably, mainly solving gib head self-detaching problem during the use existing for prior art, additionally ensure that input cost is low, income effect wants big.
To achieve these goals, the technical solution adopted in the utility model is, a kind of quick-changing mechanism preventing continuous casting intermediate inlet from stopping, it is characterized in that, described quick-changing mechanism includes body unit and locking unit, described body unit includes push rod, pin, bolt assembly, oblique wedge, gib head, and wherein push rod, pin, oblique wedge, gib head are attached by bolt assembly.Described locking unit includes cutting somebody's hair, oil cylinder, guide post one, transverse arm, spring, guide post two, copper concave surface joint, adjusting rod.Cut somebody's hair and be arranged on oil cylinder piston club head, guide post one be fixed on through the through hole of transverse arm cut somebody's hair on stretch with cylinder piston rod.On transverse arm, spring mounting hole is got through, and the back side installs spring, guide post two, copper concave surface joint, adjusting rod successively.When gib head is close to gate mechanism, adjust adjusting rod, make spring compression, gib head compress gate mechanism.With the handle on hand propelled gib head, gib head disengages gate mechanism, and quick-changing mechanism is opened.
As a kind of improvement of the present utility model, described locking unit also includes thermal insulation board, completely cuts off molten steel radiation heat, and described thermal insulation board is bolted below transverse arm.
As a kind of improvement of the present utility model, spring is installed on transverse arm, the end pacifying spring-loaded transverse arm is provided with spring-supported guide post two, and can the spherical joint the most copper concave surface joint of flexible rotating and the end plush copper of guide post two, utilize hook head component movement locus processed springs motion installing hole in transverse arm, it is to avoid spring is damaged by shearing force, by fixing spring and guiding transformation, make spring all the time by axial compressive force, it is to avoid failure by shear.
As a kind of improvement of the present utility model, disengage rotational angle, at this moment spring rotation to be followed according to gib head, the spring mounting hole on transverse arm is processed according to limit of sports record position.
Relative to prior art, the technical program provides the benefit that: realizes quick-changing mechanism and fixes the most efficiently, and the pretightning force of spring is adjustable, extends spring service life simultaneously, ensure that the kilter of spring, thus reach oil cylinder in use, fix with mechanism reliably and be connected, after this device tentative, use up till now, disconnected the watering that one steel-making disengages without there is quick-changing mechanism stops and molten steel overflow accident, and stable equipment operation is reliable, and year, economic benefit was at 500,000 yuan.
