Abstract

An assembling and disassembling device for a compressor has a substantially cylindrical bundle that is received insertably and removably on an inner circumferential surface of a substantially tubular compressor casing that is mounted horizontally and further includes: a plate-like member that is provided on an axial end portion of the bundle at an opposite side of an insertion direction so as to protrude outward in a radial direction of the bundle and a threaded-rod member that inserts and removes the bundle connected to the plate-like member into and from the compressor casing by being screwed into a threaded hole provided in the plate-like member and being rotated.

First claim

The invention claimed is:

1. An assembling and disassembling device for a compressor having a substantially cylindrical bundle that is received insertably and removably on an inner circumferential surface of a substantially tubular compressor casing that is positioned horizontally, the assembling and disassembling device comprising:
a plate-like member that is connected to an axial end portion of the bundle at an opposite side in an insertion direction of the bundle so as to protrude outward from the bundle in a radial direction thereof; and
a threaded-rod member that is rotatably received in a threaded hole provided in the plate-like member such that the bundle can be inserted and removed from the compressor casing by rotating the threaded-rod member; and
a support member that is curved along an outer circumferential surface of the bundle, the support member supporting the bundle from below by being provided below an axial end portion of the compressor casing at an opposite side of the casing in the insertion direction,
wherein one end of the threaded-rod member penetrating the plate-like member is in contact with an end of the support member, and an opposite end of the support member is in contact with an end surface of the compressor casing.

2. A compressor comprising:
a substantially tubular compressor casing; and
a substantially cylindrical bundle that is received insertably and removably on an inner circumferential surface of the compressor casing,
wherein an axial end portion of the bundle at an opposite side in an insertion direction of the bundle is provided with a plate-like-member attaching hole for attaching a plate-like member having a threaded hole through which a threaded-rod member penetrates and the threaded-rod member is threadably engaged with the threaded through hole,
wherein a support member that is curved along an outer circumferential surface of the bundle supports the bundle from below by being provided below an axial end portion of the compressor casing at an opposite side of the casing in the insertion direction, and
wherein one end of the threaded-rod member penetrating the plate-like member is in contact with an end of the support member, and an opposite end of the support member is in contact with an end surface of the compressor casing.

3. A compressor assembling and disassembling method using a compressor assembling and disassembling device, wherein the compressor assembling and disassembling device comprises:
a plate-like member that protrudes outward from a substantially cylindrical bundle in a radial direction thereof, the bundle being received insertably and removably on an inner circumferential surface of a substantially tubular compressor casing that is positioned horizontally, the plate-like member being provided on an axial end portion of the bundle at an opposite side in an insertion direction of the bundle;
a threaded-rod member that is rotatably received in a threaded hole provided in the plate-like member so that the bundle can be inserted and removed from the compressor casing by screwing the threaded-rod member into the threaded hole; and
a support member that is curved along an outer circumferential surface of the bundle and that supports the bundle from below by being provided below an axial end portion of the compressor casing at an opposite side of the casing in the insertion direction,
the compressor assembling and disassembling method comprising:
contacting one end of the threaded-rod member penetrating the plate-like member with an end of the support member, and an opposite end of the support member is in contact with an end surface of the compressor casing; and
rotating the threaded-rod member to insert or remove the bundle from the casing.
