Abstract
Discloses a self-contained and non-polluting mobile ingot extractor having a wheeled undercarriage and drawbar frame with a hitch for towing same. The extractor has longitudinal frame members carrying cross-members which carry stops and a hydraulic ram. The longitudinal axis of the stuck ingot and its mold is horizontally disposed between said stops and ram head of the hydraulic ram. A low volume-high pressure hydraulic pump exerts force through the ram head upon the stuck ingot to remove same from its mold.
Claims6
A mobile ingot extractor for use in removing a stuck ingot from its mold, said mobile ingot extractor comprising a wheeled trailer having a frame, longitudinal frame members, a drawbar frame, coupling means, cross-members, stops, ram means, self-containment means and spacer plugs;
- said longitudinal frame members being carried at one of their common ends by said wheeled-trailer frame and at their other common ends by said drawbar frame, said drawbar frame carrying said coupling means, said coupling means operatively connecting said mobile ingot extractor to a prime mover means for towing and positioning said mobile ingot extractor, said longitudinal frame members carrying said cross-members, said cross-members carrying said stops and ram means, said cross-members being relatively adjustable therebetween along the longitudinal axes of said longitudinal frame members to spatially accommodate molds of different lengths, said mold being disposed between said stop means and ram means for operative engagement by said ram means with said stuck ingot of said mold, said stops being movable laterally and radially on one of said cross-members to spatially accommodate molds of different diameters, said ram means being operable for engagement with said stuck ingot for removal of same from its said mold, said self-containment means comprising an energy supply, engine means and hydraulic pump means, said energy supply operating and running said engine means, said engine means driving said hydraulic pump means, said hydraulic pump means reciprocably driving said ram means forward to engage and move said stuck ingot forward the extent of the forward travel of said ram means or driving said ram means to its inoperative or starting position, and spacer plugs for insertion into a mold received by said mobile ingot extractor, said mold successively receiving said spacer plugs to spatially accommodate the resulting spaces caused by forward movements of said ingot through said mold corresponding to the successive forward travels of said ram means.
