Hydraulic nose tilt pouring device

Apparatus for manipulating a nose-tilt molten metal ladle or the like comprising, in combination,

• a ladle having a pouring spout projecting laterally therefrom,
• a suspension frame including an elongated vertically extending hollow enclosure positioned above said ladle and a sub-frame fixed relative to said elongated enclosure and having a horizontal portion projecting laterally relative to said enclosure and spaced vertical portions depending from said horizontal portion toward and positioned on opposite sides of and adjacent to said pouring spout,
• first pivot means adjacent said spout and attaching said vertical portions to said ladle for pivotal movement of said ladle about said first pivot means located adjacent said spout,
• first and second hydraulic cylinders fixedly positioned within said enclosure being relatively vertically aligned and arranged end-to-end and each including a ram end,
• the ram end of one cylinder projecting upwardly from said enclosure to provide a point of attachment from which said apparatus is suspended and so that said one cylinder is operative to raise said apparatus and ladle as a unit,
• the ram end of the other cylinder projecting downwardly from said enclosure toward said ladle,
• second pivot means attaching the ram end of the other cylinder to said ladle at a pivot spaced from said first pivot means so that said other cylinder is operative to raise said second pivot means relative to said first pivot so that said ladle tilts on said first pivot means to pour molten metal contained therein from said spout,
• a reservoir for hydraulic fluid connected to and supported on said suspension frame,
• hydraulic pump means supported on said suspension frame,
• hydraulic circuit means operatively connecting said reservoir, said pump means and said hydraulic cylinders, for selective operation of said first and second hydraulic cylinders,
• electric storage battery means connected to and supported on said suspension frame and operatively connected to said pump means for supplying electric power to said pump means,
• means connecting said second ram portion to said second pivot means and including vertically adjustable members for selectively varying the vertical distance from said second ram to said second pivot means,
• and said sub-frame being fixed relative to said ladle and including vertically adjustable members connected to said first pivot means for selectively varying the vertical position of said first pivot means relative to said sub-frame.

Apparatus for manipulating a nose-tilt molten metal ladle or the like comprising, in combination,

• a ladle having a pouring spout,
• a suspension frame including first pivot means connected to said ladle adjacent said spout and second pivot means connected to said ladle at a point spaced from said first pivot means, said suspension frame including an elongated vertically extending hollow enclosure positioned above said ladle,
• hydraulic cylinder means housed within said enclosure and connected to said suspension frame, said hydraulic cylinder means including a first operative portion effective when energized to raise said suspension frame and said ladle as a unit,
• said hydraulic cylinder means also including a second operative portion connected to said ladle through said second pivot means and effective when energized to raise said second pivot means relative to said first pivot means so that said ladle tilts on said first pivot means and molten metal contained in said ladle can be poured from said spout,
• said first operative portion of said hydraulic cylinder means including a first ram portion projecting upwardly from said suspension frame and providing a point of attachment from which said apparatus is suspended,
• said second operative portion of said hydraulic cylinder means including a second ram portion projecting downwardly from said suspension frame toward said ladle,
• said first operative portion of said hydraulic cylinder means comprising a first hydraulic cylinder and said first ram portion and extending vertically within said enclosure,
• said second operative portion of said hydraulic cylinder means comprising a second hydraulic cylinder and said second ram portion, said second hydraulic cylinder arranged end-to-end with said first hydraulic cylinder and extending vertically within said enclosure, and means connecting said second ram portion to said second pivot means and including vertically adjustable members for selectively varying the vertical distance from said second ram to said second pivot means,
• and a sub-frame fixed relative to said ladle and including vertically adjustable members connected to said first pivot means for selectively varying the vertical position of said first pivot means relative to said sub-frame.
