Abstract
Abstract An apparatus for simultaneously pivoting, tilting and rotating a lining brick, in particular a converter lining brick having a trapezoidal cross-section, into a position adequate for stacking has a stationary supporting stand, a carrying arm journaled on the supporting stand to be pivotable around a stationary axis, a bracing means for the lining brick journaled on one end of the carrying arm and rotatable around an axis that is skew relative to the stationary axis of the carrying arm, and a planet gear which can be turned off, whose central axis is the stationary axis of the carrying arm, and whose orbit axis is the axis of rotation of the bracing means.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
167 words
An apparatus for simultaneously pivoting, tilting and rotating a lining brick, in particular a converter lining brick having a trapezoidal cross-section, into a position adequate for stacking comprising a stationary supporting stand, a carrying arm journaled on the stationary supporting stand to be pivotable around a stationary axis, a bracing means for holding the lining brick journaled on one end of the carrying arm to be rotatable around an axis that is skew relative to the stationary axis of the carrying arm, and a planet gear capable of being disengaged provided to rotate the bracing means and having a central axis coinciding with the stationary axis of the carrying arm and an orbit axis coinciding with the axis of rotation of the bracing means whereby as the carrying arm and bracing means are each caused to turn about their respective axis by a drive means, the lining brick may be selectively turned end for end in the process of being transferred from one location to another location.
Claim 2
Independent Claim
167 words
An apparatus for simultaneously pivoting, tilting and rotating a lining brick, in particular a converter lining brick having a trapezoidal cross-section, into a position adequate for stacking comprising a stationary supporting stand, a carrying arm journaled on the stationary supporting stand to be pivotable around a stationary axis, a bracing means for holding the lining brick journaled on one end of the carrying arm to be rotatable around an axis that is skew relative to the stationary axis of the carrying arm, and a planet gear capable of being disengaged provided to rotate the bracing means and having a central axis coinciding with the stationary axis of the carrying arm and an orbit axis coinciding with the axis of rotation of the bracing means whereby as the carrying arm and bracing means are each caused to turn about their respective axis by a drive means, the lining brick may be selectively turned end for end in the process of being transferred from one location to another location.
Claim 3
Dependent Claim
46 words
An apparatus as set forth in claim 1, wherein the stationary axis of the carrying arm is inclined by 45° relative to the horizontal and the axis of rotation of the bracing means is inclined by 135° relative to the stationary axis of the carrying arm.
Claim 4
Dependent Claim
20 words
An apparatus as set forth in claim 1, wherein the planet gear has a transmission ratio of 1 : 1.
Claim 5
Dependent Claim
52 words
An apparatus as set forth in claim 1, said drive means comprising for pivotal movement of the carrying arm a pinion, a toothed rack engaging with the pinion, and pressure medium cylinder means for actuating the toothed rack, the pinion being concentrically arranged relative to the stationary axis of the carrying arm.
Claim 6
Dependent Claim
106 words
An apparatus as set forth in claim 4, further comprising a planet wheel provided for the planet gear, designed as bevel wheel and secured to the axis of rotation of the bracing means, a central wheel provided for the planet gear and designed as bevel wheel, a transmission shaft provided with corresponding bevel wheels at its ends, the planet wheel being drivable by the central wheel via the transmission shaft, a shaft provided for the central wheel, and a claw coupling for selectively connecting the pinion with the central wheel and its shaft and fixing the central wheel and its shaft on the stationary supporting stand.
Claim 7
Dependent Claim
47 words
An apparatus as set forth in claim 1, wherein the bracing means for holding the lining brick is provided with a first plate and a second plate arranged opposite the first plate, a pressure medium cylinder being provided for moving said first plate towards said second plate.
