Claim 33

Independent Claim 957 words

An apparatus for moving pipe between a pipe rack and a derrick floor comprising: a support frame having a first end, an opposed second end, a first side, an opposed second side, and a lower side, the first and second sides being connected by the lower side of the support frame to provide a carriage receiving passageway therein; an elongated carriage having a first side, an opposed second side, an upper side, a lower side, a first end and an opposed second end, the carriage being positionable within the carriage receiving passageway of the support frame; a carriage support positioned within the carriage receiving passageway and connected to the support frame such that the carriage support receives and supports the carriage in the carriage receiving passageway of the support frame; forward linkage means for pivotably connecting the first end of the carriage to the support frame, the forward linkage means movable between a lowered position and a raised position, in the lowered position of the forward linkage means the carriage being supported in a substantially horizontal position within the carriage receiving passageway of the support frame by the carriage support, in the raised position of the forward linkage means the first end of the carriage being supported in a raised, longitudinally shifted position a distance from the first end of the support frame, the opposed second end of the carriage being supported by the carriage support; a track connected to the support frame, the track being positioned between the support frame and the carriage such that the track extends from the opposed second end of the support frame in the direction of the first end of the support frame, the track comprising: a substantially vertically disposed elongated member having a first end, an opposed second end, a first side, an opposed second side, an upper side and an opposed lower side; an upper flange member having a first end, an opposed second end, an upper side and an opposed lower side; and a substantially parallel lower flange member having a first end, an opposed second end, an upper side and an opposed lower side, the upper flange member being connected to the upper side of the elongated member via the opposed lower side of the upper flange member and the lower flange being connected to the opposed lower side of the elongated member via the upper side of the lower flange member such that the upper flange member, the first side of the elongated member and the lower flange member cooperate to form a first channel therebetween, and the upper flange member, the second side of the elongated member and the lower flange member cooperate to form a second channel therebetween; track engaging means pivotally connected to the opposed second end of the carriage for slidably connecting the opposed second end portion of the carriage to the track, the track engaging means comprising: a first support plate having an upper end; at least one first wheel journally connected to the first support plate such that the first wheel is positionable within the first channel of the track for rolling engagement with the lower side of the upper flange member; at least one second wheel journally connected to the first support plate such that the second wheel is positionable on the upper flange member of the track for rolling engagement with the upper side of the upper flange member; a second support plate having an upper end; the second support plate being positioned in a parallel, spatial relationship with the first support plate; at least one first wheel journally connected to the second support plate such that the first wheel is positionable within the second channel of the track for rolling engagement with the lower side of the upper flange member; and at least one second wheel journally connected to the second support plate such that the second wheel is positionable on the upper flange member of the track for rolling engagement with the upper side of the upper flange member; a carriage support frame connected to the lower side of the carriage, the carriage support frame having a first end and a second end, the first end of the carriage support being positioned adjacent the carriage such that the first end of the carriage support is below the carriage a distance from the first end of the carriage, the second end of the carriage support extending a distance outwardly from the opposed second end of the carriage; a stop member connected to the first end of the track for engaging the first and second support plates of the track engaging means and stopping the movement of same along the track; and connecting means for pivotally connecting the first and second support plates of the track engaging means to the second end of the carriage support frame, comprising: a first linkage member having a first end portion and an opposed second end portion, the first end portion of the first linkage member pivotally connected to the first support plate and the opposed second end portion of the first linkage member pivotally connected to the second end of the carriage support frame; the first end portion of the second linkage member pivotally connected to the second support plate and the opposed second end portion of the second linkage member pivotally connected to the second end of the carriage support frame, the first and second linkage member cooperating with the stop member so that upon the first and second support plate of the track engaging means contacting the stop member the opposed second end of the carriage is movable to a raised position where the opposed second end of the carriage is supported by the first and second linkage members.
