Abstract

This compressor inserting and removing device (1) is provided with: an intermediate supporting portion (4) which supports a bundle (32), prior to insertion from a horizontal axis (L1) direction into a compressor casing (34) taking the form of a tube centered around the horizontal axis (L1), from an outer peripheral side of the bundle (32), at a position that is closer to the insertion side of the bundle (32) than an end portion (32d) on the side opposite to the insertion side of the bundle (32); a moving portion (10) which makes it possible for the intermediate supporting portion (4) and the compressor casing (34) to move relative to one another in the horizontal axis L1 direction; a threaded rod (12) which extends parallel to the horizontal axis (L1), and which is fixed at a distal end (12a) thereof to a fixing hole (34b) formed in an end surface (34a) at the insertion side of the compressor casing (34), and which passes through through-holes (6a and 7a) formed in the intermediate supporting portion (4); and a nut (13) which is attached to the threaded rod (12), in such a way as to be capable of coming into contact with the intermediate supporting portion (4), from the side that is closer to the rear end portion (32d) of the bundle (32) than the intermediate supporting portion (4).

First claim

The invention claimed is:

1. An inserting and removing device for a compressor, comprising:
an intermediate supporting portion which supports a bundle before being inserted into a compressor casing formed in a tubular shape about a horizontal axis in a direction of the horizontal axis, from an outer peripheral side of the bundle at a position closer to an insertion side than an end portion on a side opposite to the insertion side of the bundle;
a moving portion which can move the intermediate supporting portion and the compressor casing relative to each other in the direction of the horizontal axis;
a threaded rod which extends to be parallel to the horizontal axis, has a distal end fixed to a fixing hole formed on an end surface on the insertion side of the compressor casing, and is inserted into a through-hole formed in the intermediate supporting portion; and
a nut which is attached to the threaded rod so as to come into contact with the intermediate supporting portion from a side closer to the end portion of the bundle than the intermediate supporting portion.

2. This inserting and removing device for a compressor according to claim 1 , further comprising:
an end support portion which has a through-hole which is coaxially formed with the through-hole of the intermediate supporting portion and into which the threaded rod can be inserted, and supports the end portion.

3. The inserting and removing device for a compressor according to claim 1 ,
wherein the intermediate supporting portion includes
a curved plate which is formed in a curved shape following a shape of an outer periphery of the bundle,
a first support plate which includes the through-hole, extends in a direction orthogonal to a center axis of the through-hole, and is fixed to the curved plate,
a second support plate which extends to be parallel to the first support plate at a position separated from the first support plate in the direction of the center axis of the through-hole, and has a second through-hole which is coaxially formed with the through-hole and into which the threaded rod can be inserted,
a seat plate which connects the first support plate and the second support plate to each other, and
a rib plate which connects the first support plate and the second support plate at a position separated from the seat plate.

4. A method of inserting and removing a bundle, comprising:
a step of connecting a position of an outer peripheral surface of a bundle closer to an insertion side of a bundle inserted into a compressor casing than an end portion on a side opposite to the insertion side and the compressor casing to each other by an intermediate supporting portion which supports the bundle and a threaded rod which is inserted into the intermediate supporting portion, extends in an insertion direction of the bundle with respect to the compressor casing, and can be fixed to the compressor casing; and
a step of moving the bundle and the compressor casing relative to each other in the insertion direction by rotating a nut screwed to the threaded rod around a center axis of the threaded rod in a state where the nut abuts on the intermediate supporting portion.
