Abstract

A system for automated equipment cabinet leveling may include a foot leveling device for each foot of an equipment cabinet, each foot leveling device comprising a drive gear and a worm gear; a motor for each foot leveling device, each motor driving the worm gear of one of the foot leveling devices; a controller controlling the operation of each motor; and a sensor positioned on a portion of the equipment cabinet to be leveled that detects an orientation of the equipment cabinet and provides orientation data to the controller. The foot leveling device may interface with a foot shaft of the cabinet foot by a drive shaft driven by the drive gear, and the controller may drive at least one of motors to level the surface of the equipment cabinet based on the orientation data by extending or retracting at least one of the cabinet feet.

First claim

What is claimed is:

1. A system for automated equipment cabinet leveling, comprising:
a foot leveling device for each foot of an equipment cabinet comprising a plurality of cabinet feet, each foot leveling device comprising a drive gear and a worm gear;
a motor for each foot leveling device, each motor driving the worm gear of one of the feet leveling devices;
a controller interfacing with each of the motors and controlling an operation of each motor; and
a sensor positioned on a portion of the equipment cabinet to be leveled that detects an orientation of the equipment cabinet and provides orientation data to the controller;
wherein the foot leveling device interfaces with a foot shaft of the cabinet foot by a drive shaft driven by the drive gear;
wherein the controller:
drives each of the motors in a first direction to retract the cabinet feet until each of the motors skips or stalls;
drives each of the motors in a second direction at a first amperage level to extend each of the cabinet feet until each of the motors skips or stalls;
receives orientation data from the sensor;
identifies one of the motors to drive to level a surface of the equipment cabinet based on the orientation data; and
drives the identified motor at a second amperage level that is greater than the first amperage level in the second direction to level the surface of the equipment cabinet by extending the cabinet foot associated with the identified motor, wherein the second amperage prevents the identified motor from skipping or stalling.

2. The system of claim 1 , wherein the motor drives the worm gear using a flexi-shaft.

3. The system of claim 1 , wherein the motor is integral with the foot leveling device.

4. The system of claim 1 , wherein the motor comprises a stepper motor.

5. The system of claim 1 , wherein the sensor comprises an accelerometer.

6. The system of claim 1 , wherein a plurality of sensors are provided, each of the plurality of sensors sensing orientation data in a different axis.

7. The system of claim 1 , wherein the controller is configured to raise or lower the equipment cabinet uniformly by controlling the motors to extend or retract the cabinet feet simultaneously.

8. The system of claim 1 , further comprising:
an alignment sensor positioned on the equipment cabinet and configured to receive a reference signal from an alignment device, the alignment sensor providing an alignment signal to the controller;
wherein the controller controls the motors to raise or lower the equipment cabinet based on the alignment signal.

9. The system of claim 1 , wherein the foot shaft comprises a foot shaft interface that receives the drive shaft.

10. The system of claim 1 , wherein the controller comprises a user interface that receives a command to lower or raise the equipment cabinet.

11. A method for automated equipment cabinet leveling, comprising:
in a controller comprising a computer processor, the controller interfacing with a sensor positioned on a portion of an equipment cabinet to be leveled, the equipment cabinet comprising a plurality of cabinet feet, and controlling a plurality of motors, each motor driving a foot leveling device associated with one of the plurality of a cabinet foot;
providing a first amperage level to each of the plurality of motors to drive the foot level device associated with each of the plurality of cabinet feet in a first direction to retract the plurality of cabinet feet until each of the plurality of motors skips or stalls;
providing a first amperage level to each of the plurality of motors to drive the foot leveling device associated with each of the plurality of cabinet feet in a second direction to extend each of the cabinet feet;
detecting a skip or a stall by each of the plurality of motors;
receiving, from the sensor, orientation data for the equipment cabinet;
identifying one of the cabinet feet to extend or retract based on the orientation data to level the portion of the equipment cabinet; and
providing a second amperage level to the motor associated with the identified cabinet foot to drive the foot leveling device associated with the identified cabinet foot at a second amperage level that is greater than the first amperage level to extend or retract the identified cabinet foot, wherein the second amperage prevents the identified motor from skipping or stalling;
wherein the controller provides the second amperage level to the motor to extend or retract the at least one identified cabinet foot until the orientation data indicates that the portion of the cabinet is level.

12. The method of claim 11 , wherein the sensor comprises an accelerometer.

13. The method of claim 11 , wherein the sensor comprises a plurality of sensors, each sensor detecting an orientation in a different axis.

14. The method of claim 11 , wherein the foot leveling device comprises a worm gear and a drive gear and interfaces with a foot shaft for the cabinet foot by a drive shaft.

15. The method of claim 14 , wherein the motor extends or retracts the identified cabinet foot by driving the worm gear.

16. The method of claim 11 , further comprising:
controlling the plurality of motors to simultaneously raise or lower the equipment cabinet.

17. The method of claim 16 , wherein the controller controls the plurality of motors to simultaneously raise or lower the equipment cabinet until an alignment signal is received from an alignment sensor positioned on the equipment cabinet.

18. The method of claim 17 , wherein the alignment sensor comprises a photodiode configured to receive an alignment laser.

19. The method of claim 11 , further comprising:
controlling the motors to retract the plurality of cabinet feet; and
controlling the motors to extend the plurality of cabinet feet until the cabinet feet are in contact with a surface.
