Abstract

A robotic transporter system for elevator cars including: a propulsion system configured to move an elevator car through an elevator shaft; and a robotic transporter configured to move the elevator car within a parking area, the robotic transporter including: an elevator containment slot to receive the elevator car and the propulsion system of the elevator car when the elevator containment slot is aligned with the elevator shaft.

First claim

What is claimed is:

1 . A robotic transporter system for elevator cars, the robotic transporter system comprising:
a first guide beam comprising a first surface and a second surface opposite the first surface; a propulsion system configured to move an elevator car through an elevator shaft, wherein the propulsion system is a beam climber system comprising: a first wheel in contact with the first surface; and a first electric motor configured to rotate the first wheel; and a robotic transporter configured to move the elevator car within a parking area, the robotic transporter comprising:
an elevator containment slot to receive the elevator car and the propulsion system of the elevator car when the elevator containment slot is aligned with the elevator shaft;
wherein the elevator containment slot comprises a first containment slot guide beam configured to align with the first guide beam,
wherein the first guide beam extends vertically through the elevator shaft,
wherein the robotic transporter further comprises a first sensor configured to detect when the first containment slot guide beam is aligned with the first guide beam.

2 . The robotic transporter system of claim 1 , wherein the robotic transporter further comprises:
a propulsive system and wheels.

3 . The robotic transporter system of claim 1 , wherein the robotic transporter is configured to move along an X-axis and a Y-axis perpendicular to the X-axis.

4 . The robotic transporter system of claim 1 , further comprising:
a first guide rail that extends vertically through the elevator shaft.

5 . The robotic transporter system of claim 1 , further comprising:
a second guide beam that extends vertically through the elevator shaft, the second guide beam comprising a first surface of the second guide beam and a second surface of the second guide beam opposite the first surface of the second guide beam, wherein the beam climber system further comprises:
a second wheel in contact with the second surface of the first guide beam;
a third wheel in contact with the first surface of the second guide beam; and
a second electric motor configured to rotate the third wheel.

6 . The robotic transporter system of claim 5 , wherein the elevator containment slot further comprises:
a second containment slot guide beam configured to align with the second guide beam.

7 . The robotic transporter system of claim 4 , further comprising:
a second guide beam that extends vertically through the elevator shaft, the second guide beam comprising a first surface of the second guide beam and a second surface of the second guide beam opposite the first surface of the second guide beam, wherein the beam climber system further comprises:
a second wheel in contact with the second surface of the first guide beam;
a third wheel in contact with the first surface of the second guide beam; and
a second electric motor configured to rotate the third wheel.

8 . The robotic transporter system of claim 7 , wherein the elevator containment slot further comprises:
a second containment slot guide beam configured to align with the second guide beam.

9 . The robotic transporter system of claim 7 , further comprising:
a second guide rail that extends vertically through the elevator shaft, wherein the elevator containment slot further comprises:
a second containment slot guide beam configured to align with the second guide beam.

10 . The robotic transporter system of claim 1 , wherein the robotic transporter is located on a truck configured to transport the elevator car from a factory to a building where the elevator shaft is located or from the building to the factory.

11 . A method of moving an elevator car from an elevator shaft to a parking area that is outside of the elevator shaft, the method comprising:
moving a robotic transporter to an elevator shaft to pick up the elevator car; aligning an elevator car containment slot within the robotic transporter with the elevator shaft; moving, using a propulsion system, the elevator car from the elevator shaft into the elevator car containment slot, wherein the moving comprises rotating, using a first electric motor of a beam climber system, a first wheel, the first wheel being in contact with a first surface of a first guide beam; and moving the robotic transporter with the elevator car within the elevator containment slot to a location within the parking area; wherein the first guide beam extends vertically through the elevator shaft, wherein the robotic transporter further comprises a first sensor configured to detect when the first containment slot guide beam is aligned with the first guide beam.

12 . The method of claim 11 , further comprising:
aligning a first containment slot guide beam of the elevator car containment slot with the first guide beam.

13 . The method of claim 12 , further comprising:
aligning a first containment slot guide rail of the elevator car containment slot with a first guide rail that extends vertically through the elevator shaft.

14 . The method of claim 11 , wherein the moving, using the propulsion system, the elevator car from the elevator shaft into the elevator car containment slot further comprises:
rotating a second wheel, the second wheel being in contact with the second surface of the first guide beam that extends vertically through the elevator shaft; and rotating, using a second electric motor of the beam climber system, a third wheel, the third wheel being in contact with a first surface of a second guide beam that extends vertically through the elevator shaft.

15 . The method of claim 14 , further comprising:
aligning a second containment slot guide beam of the elevator car containment slot with the second guide beam.

16 . The method of claim 15 , further comprising:
aligning a second containment slot guide rail of the elevator car containment slot with a second guide rail that extends vertically through the elevator shaft.

17 . A computer program product embodied on a non-transitory computer readable medium, the computer program product including instructions that, when executed by a processor, cause the processor to perform operations comprising:
moving a robotic transporter to an elevator shaft to pick up the elevator car; aligning an elevator car containment slot within the robotic transporter with the elevator shaft; moving, using a propulsion system, the elevator car from the elevator shaft into the elevator car containment slot; and moving the robotic transporter with the elevator car within the elevator containment slot to a location within the parking area; rotating, using a first electric motor of a beam climber system, a first wheel, the first wheel being in contact with a first surface of the first guide beam; moving the robotic transporter with the elevator car within the elevator containment slot to a location within the parking area, wherein the first guide beam extends vertically through the elevator shaft, wherein the robotic transporter further comprises a first sensor configured to detect when the first containment slot guide beam is aligned with the first guide beam.
