Abstract

Systems, methods, and apparatuses for engaging, lifting, and moving objects such as wheeled cargo trailers are provided. In one embodiment, a mobile apparatus includes a transport mechanism, a frame, and one or more lift assemblies. The lift assemblies may be adjusted using one or more attached actuators that position the lift assemblies and/or components thereof for engaging and lifting an object. The transport mechanism may be autonomously operated. A vision system may be used to locate and identify objects and/or guide the mobile apparatus into position to engage and lift the objects. An adapter for a pneumatic braking system of a wheeled cargo trailer is also provided. The adapter provides a pneumatic attachment for a pressurized air source that is separate from a glad hands connector attached to the braking system.

First claim

What is claimed is:

1. A mobile apparatus for engaging and moving objects, comprising:
a frame, comprising:
a base portion,
a first elongated portion extending from the base portion, and
a second elongated portion extending from the base portion, the second elongated portion spaced from the first elongated portion,
wherein the first elongated portion and the second elongated portion extend from the base portion along a first axis which is perpendicular to a second axis;

a first lift assembly coupled to the frame and comprising:
a first lifting component,
a first actuator coupled to the first lifting component, the first actuator operable to shift the first lifting component along the first axis to different positions along a length of the frame, and
a second actuator coupled to the first lifting component and operable to shift the first lifting component along the second axis between a raised position and a lowered position;

a second lift assembly coupled to the frame and comprising:
a second lifting component,
a third actuator coupled to the first elongated portion and coupled to the second lifting component and operable to shift the second lifting component along the second axis between a raised position and a lowered position while the first elongated portion remains extending along the first axis,
a third lifting component, and
a fourth actuator coupled to the second elongated portion and coupled to the third lifting component and operable to shift the third lifting component along the second axis between a raised position and a lowered position while the second elongated portion remains extending along the first axis,
wherein the second lifting component and the third lifting component are each movable between an extended position and a retracted position, and
wherein, in the extended position, the second lifting component and the third lifting component extend further towards each other than in the retracted position; and

a transport mechanism coupled to the frame and operable to move the frame in at least one direction.

2. The mobile apparatus of claim 1 , wherein the frame further comprises:
a third elongated portion coupled to the base portion and spaced from the first elongated portion; and
a fourth elongated portion coupled to the base portion and spaced from the second elongated portion,
wherein the first lift assembly is movably coupled to a track extending along the third and fourth elongated portions.

3. The mobile apparatus of claim 1 , wherein the first actuator comprises a linear actuator that utilizes a hydraulic piston or a screw-drive, and wherein the first lifting component comprises a fifth wheel adapted to engage a kingpin mounted on a wheeled cargo trailer.

4. The mobile apparatus of claim 1 , further comprising a plurality of wheels, each of the wheels coupled to the frame or to the transport mechanism with a respective wheel attachment, wherein at least some of the plurality of wheels are steerable.

5. The mobile apparatus of claim 1 , further comprising a vision system, the vision system comprising a plurality of detectors positioned about the mobile apparatus that are communicatively connected to one or more computer processors, the vision system adapted to determine at least one of a position and an identity of objects located about the mobile apparatus.

6. The mobile apparatus of claim 5 , wherein the plurality of detectors comprise a plurality of cameras that record images of the objects located about the mobile apparatus, and wherein the vision system is configured to identify characters visible on the objects through an optical character recognition process performed on the images.

7. The mobile apparatus of claim 5 , further comprising a wireless communication system configured to communicate information provided by the vision system to a computing device separate from the mobile apparatus.

8. The mobile apparatus of claim 1 , wherein the second lifting component is elongated and is pivotally coupled to the first elongated portion of the frame, and wherein the third lifting component is elongated and is pivotally coupled to the second elongated portion of the frame, such that the second lifting component and the third lifting component are each pivotal between the extended position and the retracted position.

9. The mobile apparatus of claim 1 , wherein the second lifting component is movably coupled to the first elongated portion with one or more linear actuators operable to move the second lifting component between the extended position and the retracted position, and wherein the third lifting component is movably coupled to the second elongated portion with one or more linear actuators operable to move the third lifting component between the extended position and the retracted position.

10. The mobile apparatus of claim 1 , wherein the second lifting component is movably coupled to the first elongated portion such that it is movable to different positions along a length of the first elongated portion that extends along the first axis, and wherein the third lifting component is movably coupled to the second elongated portion such that it is movable to different positions along a length of the second elongated portion that extends along the first axis.
