Movable platform and actuating attachment
Disclosed herein is a movable platform (MP) for moving freight during cross-dock operations. The MP comprises a mechanical actuation assembly used to deploy a plurality of roller assemblies used for moving the MP. Also disclosed is an actuating attachment used to deploy the mechanical actuation assembly of the MP. The actuating attachment can be attached to a conveyance vehicle, such as a forklift, or built in to an automated guided vehicle.
1. A movable platform comprising:
a frame;
a movable drawbar extending through an opening in a first side of the frame;
a coupling assembly coupled to a first end of the drawbar;
a connection plate coupled to a second end of the drawbar,
wherein the connection plate extends in a direction perpendicular to a moving direction of the drawbar in a T-shaped configuration; and
a plurality of ramp guide assemblies coupled to the connection plate for deploying or retracting rollers based on a moving direction of the drawbar,
wherein the connection plate is contained within a rectangular channel formed in beams of the frame,
wherein a length of the rectangular channel limits movement of the connection plate from a first position to a second position when the force is exerted on the drawbar, and
wherein the length of the rectangular channel prevents the coupling assembly from entering the opening in the frame.
2. The movable platform according to claim 1 ,
wherein the connection plate is widest in a middle of the connection plate and tapers towards ends of the connection plate.
3. The movable platform according to claim 1 ,
wherein the coupling assembly is a T-bar.
4. The movable platform according to claim 1 ,
wherein the coupling assembly is a lunette eye.
5. The movable platform according to claim 1 , wherein each ramp guide assembly comprises:
a plurality of ramp guides; and
a plurality of ramp connectors, with each ramp guide removably coupled to at least one ramp connector.
6. The movable platform according to claim 1 ,
wherein the connection plate has one rounded side and angled side with a flat portion.
7. The movable platform according to claim 1 ,
wherein the frame comprises at least three longitudinal beams and at least three cross-beams.
8. The movable platform according to claim 7 , wherein the wherein the plurality of longitudinal beams comprises at least one obround channel extending across a width of the movable platform.
9. The movable platform according to claim 1 , wherein a thickness of the connection plate is less than a thickness of the rectangular channel.
10. The movable platform according to claim 1 , further comprising:
a plurality of fixed roller assemblies located at opposite ends of the movable platform.
11. The movable platform according to claim 1 , wherein at least a portion of the frame is covered by recessed decking.
