Compressor assembly method, and bundle guiding device

An assembly method for a compressor comprising:

• a bundle having a rotor;
• and
• a casing into which the bundle is inserted, using a guiding device including:
• an internal travel device capable of supporting a front end portion of the bundle in a direction of insertion of the bundle and capable of traveling on an inner peripheral surface of the casing;
• and
• an external travel device including a rear travel device and an intermediate travel device, the rear travel device being capable of supporting a rear end portion of the bundle in the direction of insertion of the bundle and capable of traveling on a base surface extending from an opening of the casing toward the rear in the direction of insertion of the bundle, and the intermediate travel device being capable of supporting the bundle between the front end portion and the rear end portion and capable of traveling on the base surface,
• wherein the rear travel device includes:
• a rear jack part capable of adjusting a vertical position of the bundle in a vertical direction which is perpendicular to the direction of insertion of the bundle, and
• a rear horizontal adjustment mechanism part capable of adjusting a horizontal position of the bundle in a horizontal direction which is perpendicular to the direction of insertion of the bundle, and
• wherein the intermediate travel device includes:
• an intermediate jack part capable of adjusting a vertical position of the bundle in a vertical direction which is perpendicular to the direction of insertion of the bundle, and
• an intermediate horizontal adjustment mechanism part capable of adjusting a horizontal position of the bundle in a horizontal direction which is perpendicular to the direction of insertion of the bundle,
• wherein, the assembly method comprising:
• an arrangement step of arranging the bundle such that the external travel device is capable of traveling on the base surface and the internal travel device is capable of traveling on the inner peripheral surface of the casing, and arranging the bundle such that an axis of the bundle in the horizontal direction is coincident with an axis of the casing in the horizontal direction using the rear horizontal adjustment mechanism part and the intermediate horizontal adjustment mechanism part;
• a vertical position adjustment step of, while measuring relative positions in the vertical direction of the inner peripheral surface of the casing and an outer peripheral surface of the bundle at the opening of the casing, adjusting a height position of the bundle supported by the external travel device on the basis of the measured relative positions in the vertical direction;
• and
• an insertion step of inserting the bundle into the casing while the vertical position adjustment step is performed.
