Abstract

The present application includes a compressor having a cylinder forming a compression chamber in which gas is compressed, a housing having a peripheral wall forming an internal space in which the compressor is stored, and a supporting member situated above the compressor in the internal space. The peripheral wall includes an opening wall in which a carry-out port is formed through which the cylinder is carried out. The supporting member extends to guide movement of a first lifting device between a position above the compressor and a position above the carry-out port. The cylinder is hung from the first lifting device.

First claim

The invention claimed is:

1. A compressing device comprising:
a compressor having a cylinder portion configured to form a compression chamber in which gas is compressed;
a housing having a peripheral wall configured to form an internal space in which the compressor is stored, the peripheral wall including an opening wall in which a carry-out port is formed so that the cylinder portion is carried out through the carry-out port;
a first lifting device having a lifting wire to be connected to the cylinder portion of the compressor;
a supporting member situated in the internal space above the compressor and extending in the internal space without protruding out of the housing so as to guide movement of the first lifting device configured to lift the cylinder portion, the cylinder portion being allowed to move toward the carry-out port with being hung by the first lifting device when the first lifting device moves along the supporting member;
a protrusion member protruding outward from the opening wall above the carry-out port; and
a second lifting device fixed at a lower part of the protrusion member, the second lifting device having a lifting wire for carrying the cylinder portion of the compressor to outside of the housing with connecting the lifting wire to the cylinder portion which has been carried near the carry-out port;
wherein the first lifting device is supported by the supporting member at a position higher than an upper edge of the carry-out port.

2. The compressing device according to claim 1 ,
wherein the protrusion member is a canopy provided for the carry-out port.

3. The compressing device according to claim 1 ,
wherein the protrusion member is detachable from the opening wall.

4. A method for carrying a cylinder portion of a compressor from a carry-out port formed in a peripheral wall of a housing configured to form an internal space in which the compressor is stored, the cylinder portion forming a compression chamber in which gas is compressed, the method comprising:
connecting a lifting wire of a first lifting device to the cylinder portion of the compressor, the first lifting device being supported by a supporting member at a position higher than an upper edge of the carry-out port, the supporting member being situated above the compressor in the internal space and extending in the internal space without protruding outside the housing;
lifting the cylinder portion by using the first lifting device;
moving the first lifting device along the supporting member to carry the cylinder portion to the carry-out port, the cylinder portion being hung by the first lifting device;
connecting a lifting wire of a second lifting device to the cylinder portion which has been carried to the carry-out port, the lifting wire of the second lifting device extending obliquely downward into the internal space through the carry-out port from the second lifting device fixed at a lower part of a protrusion member protruding outward from the opening wall above the carry-out port; and
carrying the cylinder portion out of the carry-out port with the second lifting device by winding up the lifting wire of the second lifting device connected to the cylinder portion.

5. A compressing device comprising:
a compressor having a cylinder portion configured to form a compression chamber in which gas is compressed;
a housing having a peripheral wall configured to form an internal space in which the compressor is stored, the peripheral wall including an opening wall in which a carry-out port is formed so that the cylinder portion is carried out through the carry-out port;
a first lifting device having a lifting wire to be connected to the cylinder portion of the compressor;
a supporting member situated in the internal space above the compressor and extending in the internal space without protruding out of the housing so as to guide movement of the first lifting device configured to lift the cylinder portion, the cylinder portion being allowed to move toward the carry-out port with being hung by the first lifting device when the first lifting device moves along the supporting member;
a protrusion member protruding outward from the opening wall above the carry-out port; and
a second lifting device having a lifting wire for carrying the cylinder portion of the compressor to outside of the housing with connecting the lifting wire of the second lifting device to the cylinder portion which has been carried near the carry-out port, the second lifting device being supported by the protrusion member;
wherein the second lifting device is provided at a position lower than the first lifting device.
