Heavy compressor valve lifting tool and associated methods
Embodiments of a heavy compressor valve removal tool to remove and lift heavy compressor valves and associated methods are provided. An embodiment of a heavy-compressor valve removal tool can include one or more valve interfacing surfaces to position along, interface with, and abuttingly contact a plurality of outer surfaces when positioned around a perimeter of a compressor valve. The tool also can include one or more reinforcing arms connected to the one or more valve interfacing surfaces to reinforce the one or more valve interfacing surfaces when lifting the heavy compressor valve and one or more tool lifting arms connected to the one or more reinforcing arms to lift the heavy compressor valve from a designated position when the tool is positioned around a perimeter of the heavy compressor valve.
1. A heavy compressor valve removal tool to remove and lift heavy compressor valves, the tool comprising:
a weight bearing annularly-shaped valve interfacing surface to interface with an outer surface of a perimeter of a compressor valve when positioned adjacent the compressor valve, the valve interfacing surface conforming to a shape of the outer surface of the compressor valve, to bear the weight of the compressor valve when the compressor valve is lifted, and to underlie the compressor valve when the weight bearing valve interfacing surface interfaces with the outer surface of the compressor valve;
one or more reinforcing arms connected to the valve interfacing surface, the one or more reinforcing arms being substantially parallel to the compressor valve when the valve interfacing surface interfaces with the outer surface of the compressor valve, and wherein the one or more reinforcing arms connect to a medial portion of and extend substantially across the diameter of the annular valve interfacing surface;
one or more tool lifting arms connected to the one or more reinforcing arms at a first end of the one or more tool lifting arms proximate the one or more reinforcing arms; and
a lifting mechanism connected to the one or more tool lifting arms at a second end of the one or more tool lifting arms opposite the first end, the heavy compressor valve removal tool adapted to lift the compressor valve when the valve interfacing surface interfaces with the outer surface of the compressor valve.
2. The tool of claim 1 , wherein the lifting mechanism comprises an industrial crane.
3. The tool of claim 1 , wherein the one or more reinforcing arms comprises a beam member arm having one or more of: (a) a plurality of openings formed in the beam member arm; and (b) a skeletal structure, to thereby reduce the weight of the beam member and overall weight of the tool and yet strengthen the valve interfacing surface when lifting the compressor valve.
4. The tool of claim 1 , wherein the annular shape of the interface surface comprises a ring to interface with a similarly-sized, ring-shaped outer surface of the compressor valve, and wherein the one or more reinforcing arms comprises a reinforcing arm that substantially bisects the ring of the tool.
5. The tool of claim 1 , wherein the one or more reinforcing arms have a square cross-section.
6. A method of lifting a heavy compressor valve with a heavy compressor valve lifting tool, the method comprising:
positioning a weight bearing annular valve interfacing surface of the heavy compressor valve lifting tool adjacent and to underlie an outer surface of a perimeter of a compressor valve so that the weight bearing valve interfacing surface bears the weight of the compressor valve when the compressor valve is moved away from an associated compressor;
securing the valve interfacing surface of the heavy compressor valve lifting tool against the outer surface of the compressor valve; and
moving the compressor valve away from the compressor with a lifting mechanism connected to the heavy compressor valve lifting tool
wherein the heavy compressor valve lifting tool further comprises one or more reinforcing arms connected to the one or more valve interfacing surfaces; and
wherein the one or more reinforcing arms connects to a medial portion of and extends substantially across the diameter of the annular valve interfacing surface.
7. The method of claim 6 , wherein the heavy compressor valve lifting tool further comprises:
one or more tool lifting arms connected to the one or more reinforcing arms at a first end of the one or more tool lifting arms; and
wherein the lifting mechanism is connected to the one or more tool lifting arms at a second end of the one or more tool lifting arms, the heavy compressor valve removal tool adapted to lift the compressor valve when the valve interfacing surface interfaces with the outer surface of the compressor valve.
8. The method of claim 7 , wherein the lifting mechanism comprises an industrial crane.
9. The method of claim 7 , wherein the one or more reinforcing arms comprises a beam member arm having one or more of: (a) a plurality of openings formed in the beam member arm; and (b) a skeletal structure, to thereby reduce the weight to the beam member and overall weight of the tool and yet strengthen the valve interfacing surface when lifting the compressor valve.
10. The method of claim 7 , wherein the annular shape of the interface surface comprises a ring to interface with a similarly-sized, ring-shaped outer surface of the compressor valve, and wherein the one or more reinforcing arms comprises a reinforcing arm that substantially bisects the ring of the tool.
11. The method of claim 7 , wherein one or more reinforcing arms has a square cross-section.
12. The method of claim 6 , further comprising: manipulating the compressor valve with the heavy compressor valve lifting tool as required to gain access to the compressor.
