Abstract
An extensible support apparatus for extending the length of an endless conveyor belt system including a set of roller supporting frames arranged in a row with each having a vertically extending framework with rollers for the conveyor rotatably mounted thereon and a horizontally extending elongate frame member. Connectors are mounted on the frame members so that each is movable horizontally along the frame member of an adjacent supporting frame. A loading apparatus is also provided for arranging this support apparatus in the conveyor belt system. The loading apparatus includes a base frame, a loading frame pivotably mounted on one side of the base frame and a horizontally movable supporting frame capable of supporting the extensible support apparatus.
Claims24
An extensible support apparatus for an endless conveyor belt comprising a set of roller supporting frames arranged in a row with each supporting frame including a substantially planar, vertically extending framework with rollers for said conveyor belt rotatably mounted thereon and a horizontally extending elongate frame member connected to said vertically extending framework, this framework extending substantially transversely of its respective frame member, connectors mounted on said frame members, each connector being movable in a generally horizontal direction along the elongate frame member of an adjacent roller supporting frame and movably connecting its respective roller supporting frame to said adjacent roller supporting frame, wherein the set of roller supporting frames is able to extend and retract between a compact transport configuration in which the vertically extending frameworks are arranged side-by-side and an extended configuration for supporting said conveyor belt.
A loading apparatus for arranging an extensible support apparatus in an endless conveyor belt system, said loading apparatus comprising:
- a generally horizontal base frame capable of resting on a horizontally extending supporting surface in longitudinal alignment with said conveyor belt system;
- a loading frame pivotably mounted on one side of said base frame, said one side extending substantially parallel to a longitudinal axis of the conveyor belt system, said loading frame being pivotable from a horizontal position where said loading frame extends outwardly from said one side of the base frame to an elevated position where said loading frame extends vertically;
- pivoting means connected to said loading frame for pivoting same from said horizontal position to said elevated position;
- a movable supporting frame capable of supporting said extensible support apparatus and horizontally movable between a first position located over said base frame and a second position located over said loading frame when the latter is in its horizontal position;
- and
- drive means for moving said supporting frame from said second position to said first position.
A loading apparatus for arranging a conveyor extending apparatus in an elongate endless conveyor belt system, said loading apparatus comprising:
- a horizontally extending base frame capable of supporting said conveyor extending apparatus by means of support surfaces formed thereon, said base frame having a longitudinal central axis alignable with said conveyor belt system in a transverse direction thereof;
- frame means for horizontally and outwardly extending said base frame on a side thereof parallel to said longitudinal central axis, said frame means being adapted to extend substantially outwardly from one longitudinal side of said conveyor belt system during use thereof;
- a movable supporting frame capable of supporting said conveyor extending apparatus on a top thereof and horizontally movable between a first position where said supporting frame is located over said base frame and is supported by said support surfaces thereon and a second position where said supporting frame is located over and is supported by said frame means;
- and
- power drive means for moving said supporting frame from said second position to said first position.
A belt lifting apparatus usable with an endless conveyor belt system in order to add an extension to said conveyor belt system, said belt lifting apparatus comprising:
- a rigid, horizontally extending base frame adapted to lie on a supporting surface;
- an upwardly extending supporting framework mounted on said base frame and supported thereby;
- lifting frame means for raising a length of conveyor belt temporarily, said frame means being pivotably connected at one end to said supporting framework;
- drive means connected to said lifting frame means for pivoting said frame means from a lowered position to a raised position;
- and
- a belt lifting frame device mounted on said frame means and adapted to engage a lower surface of said length of conveyor belt.
