Abstract
Abstract An apparatus for holding and transporting a hot metal mixer tank in a metallurgical plant includes a platform car having wheels for running over a trackway and a support at each end for removably engaging a large hot metal mixer. The hot metal mixer tank is supported on axle or tilt axle mounted at each end of the carriage. Each pivot axle includes at least two arms which carry bearing shells on each side of the associated end of the mixing tank. The mixing tank carries transversely extending horizontal position pins which extend outwardly from each side and rest in the open top bearing shells. The tops of the shells may be closed by pivotal cover plates which are bolted in position when closed. The supporting pivot axles on the track car also carry upper and lower rigid extensions having adjustable back pressure bolt members which may be threaded inwardly or outwardly in order to provide a longitudinal bearing pressure against the end surface of the mixing tank when the latter is oriented in position on the bearing journals and the side bearing pins are locked in the open shell supports.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
156 words
A hot metal mixer tank support for metallurgical plants, comprising a mounting base adapted to be located on an undercarriage which is movable, at least one bearing support on said mounting base, a tilt axle member rotatable in said bearing support and having a portion with at least two spaced-apart opened-top bearing surfaces, a hot metal mixer tank having at least two position pins extending substantially radially outwardly from an end thereof and generally transversely to the longitudinal axis of said tank and engaged on respective ones of said bearing surfaces, said tank with said pins being liftable off said opened bearing surfaces, and a closure member defining at least one back pressure bearing surface acting on said position pins, said closure member being pivotally movable between an open position to permit removal of said pins from said bearing surfaces and a closed position to cover and hold said pins for rotational movement of said tank.
Claim 2
Dependent Claim
156 words
A hot metal mixer tank support for metallurgical plants, comprising a mounting base adapted to be located on an undercarriage which is movable, at least one bearing support on said mounting base, a tilt axle member rotatable in said bearing support and having a portion with at least two spaced-apart opened-top bearing surfaces, a hot metal mixer tank having at least two position pins extending substantially radially outwardly from an end thereof and generally transversely to the longitudinal axis of said tank and engaged on respective ones of said bearing surfaces, said tank with said pins being liftable off said opened bearing surfaces, and a closure member defining at least one back pressure bearing surface acting on said position pins, said closure member being pivotally movable between an open position to permit removal of said pins from said bearing surfaces and a closed position to cover and hold said pins for rotational movement of said tank.
Claim 3
Dependent Claim
32 words
A hot metal mixer tank support according to claim 1, wherein said position pins are of cylindrical construction and have curved surfaces which bear against correspondingly curved surfaces of said bearing surfaces.
Claim 4
Dependent Claim
40 words
A hot metal mixer tank support according to claim 1, wherein said bearing surfaces comprise curved recesses open on one side, said cover member being hingedly connected to said tilt axle portion and being pivotal to close said bearing surfaces.
Claim 5
Dependent Claim
38 words
A hot metal mixer tank support according to claim 1, wherein said tilt axle member portion includes at least one threaded screw member threaded therein and being adjustably displaceable longitudinally to bear against an end of said tank.
Claim 6
Dependent Claim
171 words
A hot metal mixer tank support for metallurgical plants, comprising a mounting base adapted to be located on an undercarriage which is movable, at least one bearing support on said mounting base, a tilt axle member rotatable in said bearing support and having a portion with at least two spaced-apart bearing surfaces, a hot metal mixer tank having at least two position pins extending substantially radially outwardly from an end thereof and generally transversely to the longitudinal axis of said tank and engaged on said bearing surfaces, means defining at least one back pressure bearing surface acting on said tank, all of said bearing surfaces and said back pressure bearing surfaces enclosing the longitudinally extending centerline of said tank, said tilt axle member portion being forked and includes first and second spaced-apart arms, each of said arms having a curved recess forming said bearing surfaces, and a cover pivoted to each of said arms and being movable downwardly to close said bearing surfaces and engage over a positioning pin disposed therein.
Claim 7
Dependent Claim
171 words
A hot metal mixer tank support for metallurgical plants, comprising a mounting base adapted to be located on an undercarriage which is movable, at least one bearing support on said mounting base, a tilt axle member rotatable in said bearing support and having a portion with at least two spaced-apart bearing surfaces, a hot metal mixer tank having at least two position pins extending substantially radially outwardly from an end thereof and generally transversely to the longitudinal axis of said tank and engaged on said bearing surfaces, means defining at least one back pressure bearing surface acting on said tank, all of said bearing surfaces and said back pressure bearing surfaces enclosing the longitudinally extending centerline of said tank, said tilt axle member portion being forked and includes first and second spaced-apart arms, each of said arms having a curved recess forming said bearing surfaces, and a cover pivoted to each of said arms and being movable downwardly to close said bearing surfaces and engage over a positioning pin disposed therein.
Claim 8
Dependent Claim
32 words
A hot metal mixer tank support according to claim 5, including an I-bolt pivoted on each of said arms and engaGeable with said cover for securing said cover in a closed position.
Claim 9
Dependent Claim
165 words
A hot metal mixer tank support for metallurgical plants, comprising a mounting base adapted to be located on an undercarriage which is movable, at least one bearing support on said mounting base, a tilt axle member rotatable in said bearing support and having a portion with at least two spaced-apart bearing surfaces, a hot metal mixer tank having at least two position pins extending substantially radially outwardly from an end thereof and generally transversely to the longitudinal axis of said tank and engaged on said bearing surfaces, and means defining at least one back pressure bearing surface acting on said tank, all of said bearing surfaces and said back pressure bearing surfaces enclosing the longitudinally extending centerline of said tank, said tilt axle member portion including at least three substantially radially extending arms having surfaces forming said bearing surfaces, said mixing tank having at least three correspondingly oriented position pins extending substantially radially outwardly therefrom and engaged on corresponding ones of said arm bearing surfaces.
Claim 10
Dependent Claim
165 words
A hot metal mixer tank support for metallurgical plants, comprising a mounting base adapted to be located on an undercarriage which is movable, at least one bearing support on said mounting base, a tilt axle member rotatable in said bearing support and having a portion with at least two spaced-apart bearing surfaces, a hot metal mixer tank having at least two position pins extending substantially radially outwardly from an end thereof and generally transversely to the longitudinal axis of said tank and engaged on said bearing surfaces, and means defining at least one back pressure bearing surface acting on said tank, all of said bearing surfaces and said back pressure bearing surfaces enclosing the longitudinally extending centerline of said tank, said tilt axle member portion including at least three substantially radially extending arms having surfaces forming said bearing surfaces, said mixing tank having at least three correspondingly oriented position pins extending substantially radially outwardly therefrom and engaged on corresponding ones of said arm bearing surfaces.
