Abstract

A system for inspecting a turbomachine is provided. The system includes a traverse actuator system and a pressure isolation system connected to the traverse actuator system. The pressure isolation system is configured to maintain a pressure resistant seal around a probe. A gimbal mount is connected to the pressure isolation system. The system is configured to move the probe into and out of the turbomachine.

First claim

The invention claimed is:

1. A system for inspecting a turbomachine, the system comprising:
a traverse actuator system comprising a carriage configured to move a probe in a linear or radial direction into and out of the turbomachine, and a mounting plate attached to a rail, the rail supports both a pressure isolation system and a gimbal mount, the mounting plate is configured to align with a complementary mounting plate of the traverse actuator system, a plurality of keys are interposed between the mounting plate and the complementary mounting plate to ensure alignment between the traverse actuator system and the gimbal mount;
the pressure isolation system connected to the traverse actuator system, the pressure isolation system configured to maintain a pressure resistant seal around the probe;
the gimbal mount connected to the pressure isolation system; and
wherein the system is configured to move the probe into and out of the turbomachine.

2. The system of claim 1 , the traverse actuator system further comprising:
a track having a plurality of linearly arranged teeth, the track configured for operation with the carriage;
a motor operably connected with the carriage and track, the motor configured to engage the plurality of linearly arranged teeth so that operation of the motor forces the carriage to move along the track.

3. The system of claim 2 , the traverse actuator system further comprising:
an enclosure configured to operate in hazardous environments, the enclosure housing the motor.

4. The system of claim 2 , the traverse actuator system further comprising:
a yaw drive configured to rotate the probe about a radial axis of the turbomachine.

5. The system of claim 1 , the traverse actuator system further comprising:
a camera configured to observe an insertion location of the probe, the camera configured to operate in hazardous environments; and
wherein the camera is connected to a monitoring station having a display.

6. The system of claim 1 , the traverse actuator system further comprising:
a leg assembly attached to a rail of the traverse actuator system, the leg assembly configured to stabilize the traverse actuator system.

7. The system of claim 6 , leg assembly further comprising:
a plurality of adjustable length legs configured to lock in position at a desired length.

8. The system of claim 1 , the traverse actuator system further comprising: an articulated cable guide comprised of a plurality of chain links, the articulated cable guide configured to retain the plurality of cables, and to follow movement of the carriage so that the cables avoid catching on obstructions.

9. The system of claim 1 , the probe further comprising at least one of:
a pressure probe having a plurality of ports, a moisture probe, a temperature probe, a camera.

10. The system of claim 1 , the probe further comprising:
a pressure probe having a plurality of ports, and an elongated shaft having a sensor head located at one end and a plurality of output ports located at an opposing end of the elongated shaft.

11. The system of claim 1 , the pressure isolation system further comprising:
a valve seal located between the gimbal mount and a pressure seal, the valve seal configured to isolate the pressure seal from the gimbal mount when the probe is not in the valve seal.

12. The system of claim 11 , wherein the valve seal is at least one of:
a ball valve seal or a guillotine seal.

13. The system of claim 11 , the pressure isolation system further comprising:
a probe bearing located adjacent to the pressure seal, the probe bearing configured to facilitate back and forth movement of the probe by reducing friction.

14. The system of claim 13 , wherein the probe bearing is comprised of at least one of:
roller bearings, ball bearings, or low friction material.

15. The system of claim 11 , wherein the pressure seal is connected to a pressurized source or a vacuum source.

16. The system of claim 1 , the gimbal mount further comprising:
a plurality of turnbuckles located at equal intervals around the gimbal mount; and
wherein the gimbal mount is configured to be mounted to a port or a vessel flange of the turbomachine, and adjustment of the turnbuckles translates into a radial or axial adjustment of a sensor head position for the probe.

17. The system of claim 16 , wherein there are four turnbuckles located at 90 degree intervals around the gimbal mount; and
wherein adjustment of a first set of turnbuckles spaced by 180 degrees results in an axial movement of the sensor head, and adjustment of a second set of turnbuckles spaced by 180 degrees results in a tangential movement of the sensor head, with respect to the turbomachine, and the first set of turnbuckles is 90 degrees offset from the second set of turnbuckles.

18. A system for inspecting an operating turbomachine, the system comprising:
a traverse actuator system, the traverse actuator system comprising a carriage configured to move a probe in a linear or radial direction into and out of the turbomachine, the traverse actuator system having a track with a plurality of linearly arranged teeth, the track configured for operation with the carriage, a motor operably connected with the carriage and the track, the motor configured to engage the plurality of linearly arranged teeth so that operation of the motor forces the carriage to move along the track, an enclosure configured to operate in hazardous environments, the enclosure housing the motor, a yaw drive configured to rotate the probe about a radial axis of the turbomachine, and an articulated cable guide comprised of a plurality of chain links, the articulated cable guide configured to retain a plurality of cables, and to follow movement of the carriage so that the plurality of cables avoid catching on obstructions;
a pressure isolation system connected to the traverse actuator system, the pressure isolation system configured to maintain a pressure resistant seal around the probe, the pressure isolation system having a valve seal located between the gimbal mount and a pressure seal, the valve seal configured to isolate the pressure seal from the gimbal mount when the probe is not in the valve seal;
a gimbal mount connected to the pressure isolation system, the gimbal mount having
a plurality of turnbuckles located at equal intervals around the gimbal mount; and wherein the gimbal mount is configured to be mounted to a port or a vessel flange of the turbomachine, and adjustment of the turnbuckles translates into a radial or axial adjustment of a sensor head position for the probe; and
wherein the system is configured to move the probe into and out of the operating turbomachine.

19. A system for inspecting a turbomachine, the system comprising:
a traverse actuator system;
a pressure isolation system connected to the traverse actuator system, the pressure isolation system configured to maintain a pressure resistant seal around a probe, the pressure isolation system comprising a valve seal located between a gimbal mount and a pressure seal, the valve seal configured to isolate the pressure seal from the gimbal mount when the probe is not in the valve seal, wherein the valve seal is at least one of, a ball valve seal or a guillotine seal;
