Vehicle Adapted To Freely Travel Three-Dimensionally By Magnetic Force And Wheel For The Vehicle

View page
US Patent:
53558073, Oct 18, 1994
Filed:
Jan 28, 1993
Appl. No.:
8/027736
Inventors:
Ronald E. Pelrine - Menlo Park CA
Eric A. Edwards - Menlo Park CA
Lawrence S. Gullman - La Honda CA
Assignee:
Osaka Gas Co., Ltd.
International Classification:
B61C 1504
B61B 1310
US Classification:
105 78
Abstract:
A vehicle is provided for moving in pipes to determine the condition of the interior of the pipes. The vehicle has at least on wheel which is capable of travelling on walls of magnetic material. Each wheel comprises an outer wheel member having an annular peripheral wall and an inner wheel member including a portion of a magnetically permeable material. The inner wheel member has an outside diameter smaller that the inside diameter of the outer wheel member and is rollable on the inner peripheral surface of the outer wheel member. A magnet is provided in the inner wheel member having magnetic poles in contact with the permeable portion of the inner wheel. The vehicle is capable of moving through pipes without being blocked by obstacles such as a vertical wall extending from a horizontal surface. A sensor is mounted on the vehicle and a sensor processing module receives distance and time data and processes the data to determine whether the pipe is clear or obstructed.

US Patent:
52208699, Jun 22, 1993
Filed:
Aug 7, 1991
Appl. No.:
7/741330
Inventors:
Ronald E. Pelrine - Menlo Park CA
Eric A. Edwards - Menlo Park CA
Lawrence S. Gullman - La Honda CA
Assignee:
Osaka Gas Company, Ltd.
International Classification:
B61C 1504
B61B 1310
US Classification:
105 78
Abstract:
A vehicle is provided for moving within pipes to determine the condition of the interior of the pipes. The vehicle has at least one wheel which is capable of travelling on walls of magnetic material. Each wheel comprises an outer wheel member having an annular peripheral wall with an inner wheel member including a portion of magnetically permeable material. The inner wheel member has an outside diameter smaller than the inside diameter of the outer wheel member and is rollable on the inner peripheral surface of the outer wheel member. A magnet is provided in the inner wheel member having magnetic poles in contact with the permeable portion of the inner wheel. The vehicle is capable of moving through pipes without being blocked by obstacles such as a vertical wall extending from a horizontal surface. A sensor is mounted on the vehicle and a sensor processing module receives distance and time data and processes the data to determine whether the pipe is clear or obstructed.

US Patent:
53885287, Feb 14, 1995
Filed:
Feb 24, 1994
Appl. No.:
8/201088
Inventors:
Ronald E. Pelrine - Menlo Park CA
Eric A. Edwards - Menlo Park CA
Lawrence S. Gullman - La Honda CA
Assignee:
Osaka Gas Company, Limited
International Classification:
B61C 1504
B61B 1310
US Classification:
105 78
Abstract:
A vehicle is provided for moving within pipes to determine the condition of the interior of the pipes. The vehicle has at least one wheel which is capable of travelling on walls of magnetic material. Each wheel comprises an outer wheel member having an annular peripheral wall. An arm is rotatably mounted on the central portion of the outer wheel member. The arm has a pair of magnetically permeable members disposed widthwise of the vehicle body. A magnet is mounted on the arm with its poles in contact with the pair of magnetically permeable members. The arm can be rotated and freely oriented toward the running surface magnetically to hold the wheel to the running surface. The vehicle is capable of moving through pipes without being blocked by obstacles such as a vertical wall extending from a horizontal surface. A sensor is mounted on the vehicle and a sensor processing module receives distance and time data and processes the data to determine whether the pipe is clear or obstructed.
