Abstract
Abstract A fixture for shop assembly of superheater and/or reheater modules including a structural frame having accurately machined surfaces to enable exact positioning of a segment of a superheater or reheater header in a particular orientation with respect to a lifting and shipping frame mounted on a fixed reference base. The module may then be completed by placing individual superheater or reheater tube panels in the frame and joining them to the header.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
107 words
An apparatus for shop assembly of superheater or reheater modules comprising: a fixed reference base, a first support means mounted on said base, an upstanding structural frame tower mounted on said base, accurately machined surfaces particularly positioned on said structural frame tower, a second support means for supporting in a vertical orientation a segment of a header to which tubes supported by said first support means are to be joined to form said super-heater or reheater module, and means for accurately positioning said second supporting means on said machined surface of said structural frame tower so as to maintain a particular relationship to said firs support means.
Claim 2
Independent Claim
107 words
An apparatus for shop assembly of superheater or reheater modules comprising: a fixed reference base, a first support means mounted on said base, an upstanding structural frame tower mounted on said base, accurately machined surfaces particularly positioned on said structural frame tower, a second support means for supporting in a vertical orientation a segment of a header to which tubes supported by said first support means are to be joined to form said super-heater or reheater module, and means for accurately positioning said second supporting means on said machined surface of said structural frame tower so as to maintain a particular relationship to said firs support means.
Claim 3
Dependent Claim
24 words
The apparatus of claim 1 wherein said accurately machined surfaces include plural transverse elements fixed to said structural frame tower at spaced vertical intervals.
Claim 4
Dependent Claim
61 words
The apparatus of claim 2 wherein the means for positioning said second support means includes at least one mounting plate, said at least one mounting plate supported by and transversely movable with respect to said machined surfaces of said structural frame tower, said mounting plate further having complementary accurately machined surfaces mating with said machined surfaces of said structural frame tower.
Claim 5
Dependent Claim
29 words
The apparatus of claim 3 wherein the means for positioning said support means includes plural mounting plates, relatively movable with respect to each other for accurate relative positioning thereof.
Claim 6
Dependent Claim
24 words
The apparatus of claim 3 wherein said second support means further includes a header support base mounted on said at least one mounting plate.
Claim 7
Dependent Claim
31 words
The apparatus of claim 5 wherein said header support base includes a longitudinal trackway and a plurality of V-slide assemblies mounted on said trackway for selective relative movement with respect thereto.
Claim 8
Dependent Claim
70 words
The apparatus of claim 6 wherein said V-slide assemblies include a base plate slidable along said longitudinal trackway, a standard extending outwardly from said base plate, said standard having guide bearings thereon, a plate slidably mounted in said guide bearings having a V-shaped notch in one end opposite said bottom plate for adjustable support engagement with said header, and a retention means for retaining said header against said V-shaped notch.
Claim 9
Dependent Claim
27 words
The apparatus of claim 7 wherein said retention means is an adjustable cable means entrained about saId header and fixed at its ends to said base plate.
Claim 10
Dependent Claim
45 words
The apparatus of claim 7 wherein said header support base further includes a first jack means for moving said plate of said V-slide assemblies in said guide bearings, and a second jack means for positioning said header longitudinally with respect to said header support base.
