Drive unit mount for reciprocating floor conveyor

Primary Examiner: Reeves; Robert B.

Attorney, Agent or Firm: Barnard; Delbert J.
A unitary framework for a reciprocating floor conveyor is positioned within a space between a pair of longitudinally extending main beams (110), which may constitute portions of a preexisting support structure in a truck or trailer, for example. Telescopic tubular connector members (102) carried by a plurality of outwardly projecting support arms (18) are telescopically moved outwardly to place their outer ends against inner surface portions of the beams (110), and such outer ends of connector members (102) are welded to the beams (110). The telescopic engagement between these members (102) and the outwardly projecting arms (18) hold the framework in position. Then, the inner ends of these connector members (102) are welded to the arms (18), for completing the connection at these locations. The framework comprises a pair of longitudinally spaced apart, laterally extending king post trusses (10, 12), the apexes of which are directed downwardly. These trusses (10, 12) are interconnected by a pair of laterally spaced apart, longitudinally extending tie beams (14, 16). The tie beams (14, 16) are connected to the ends of, and form portions of, a pair of slide bearing assemblies (30, 32) which are carried by the two trusses (10, 12). These bearing assemblies (30, 32) include aligned guideways for receiving opposite end portions of longitudinal drive tubes (34, 36, 38). |

DETAILED DESCRIPTION I claim: 1.
For use with a support frame for a reciprocating floor conveyor of a type comprising a plurality of side-by-side arranged floor members, said support frame being of a type comprising a pair of longitudinally extending main frame members which are laterally spaced apart a distance that is substantially less than the width of the conveyor, a drive unit comprising: a unitary framework including a pair of laterally extending, longitudinally spaced apart transverse frame beams, each of which is of a length slightly smaller than the lateral distance between the two main frame members, and each of which includes a laterally outwardly projecting mounting end portion, and a pair of longitudinally extending, laterally spaced apart tie beams interconnecting intermediate portions of the two transverse frame beams; a guide bearing structure carried by each said transverse frame beam, each said guide bearing structure comprising means forming at least three parallel guideways, each of which has an axis which extends in the direction of floor member movement, and each of which is aligned with a corresponding guideway carried by the other transverse frame beam; a separate longitudinal drive rod disposed in each pair of aligned guideways; a transverse drive beam for each drive rod, said transverse drive beams being perpendicular to the longitudinal drive rods, and each being secured to its drive rod where they cross each other; said transverse drive beams being substantially longer than the distance between the two main frame members, and each including side wing portions which project outwardly beyond the two main frame members, said transverse drive beams each carrying connector means by which it can be connected to a plurality of floor members; and a short securement tube member associated with each end portion of each transverse frame beam, each such tube member being telescopically mounted onto its beam end portion and being movable inwardly along such beam end portion, such that the drive unit can be positioned between the two main frame members, and said tubular members can be slid outwardly and welded at their outer ends to the main frame members, and then at their inner ends to the end portions of the transverse frame beams, to in that manner secure the unit to the main frame members
