Definitions

  • 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.
  • a shop assembly fixture which has specifically machined surfaces to enable accurate positioning of a segment of a superheater or reheater header in a vertical orientation with respect to a lifting and shipping frame. Individual tube panels are placed in the frame and joined to the header until a complete module is built up. The module may then be conveniently shipped to the erection site in its frame where it may be positioned and joined to similar modules to form the unitary superheater or reheater structure.
  • FIG. 2 is a plan view of the structural frame tower and module support of FIG. 1.
  • FIG. 4 is a plan view of the mounting plate of FIG. 1.
  • FIG. 5 is a side elevational view of the mounting plate of FIG. 4.
  • FIG. 7 is a side elevational view of the V-slide base of FIG.
  • a header locating plate 84 is positioned on the standard 64 and has tracks 86 which are engaged with guide bearings 68 of the V-slide assembly 60 so as to permit relative movement therebetween.
  • the header locating plate 84 has a V-notch 88 in the outwardly extending end (FIG. 8 shows two half views of the header locating plate 84, the first header locating plate 84 with notch 88 for the purpose of supporting large headers and the second header locating plate 84' with notch 8 8 for smaller headers) and a ram reaction plate 90 mounted centrally thereon. As seen in FIG.
  • the assembly fixture 12 is utilized in assembly of superheater or reheater elements or modules 10 in the following manner.
  • a segment of the superheater or reheater header 98 having tube nipples 100 extending therefrom is positioned on the header locating plates 84 of the V-slide assemblies 60, the V-slide assemblies in turn being positioned on the V-slide base 42 so as to support the ends of the header 98 and clamped in the supporting position by clamps 74.
  • the header 98 is retained against the header locating plates 84 by the header retention cables 82 which are locked by the locking handles 78.
  • the end of the header 98 is supported by the header support means 56 and longitudinal positioning jack 54.
  • the V-slide base 42 (best shown in FIG. 7) which serves to support the header segment of module is comprised of a structural base 44 upon which are mounted guide rollers 46 which engage the notches 40 of the V-slide base supports 38 of the mounting plate assembly 26.
  • the base 44 has an upper extension 48 which in turn has a series of holes 50 to permit lifting and positioning of the V-slide base 42.
  • the structural base 44 has a lower extension 52 which supports a longitudinal positioning jack 54 and a header support means 56.
  • 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 surfaces of said structural frame tower so as to maintain a particular relationship to said first support means.
  • accurately machined surfaces include plural transverse elements fixed to said structural frame tower at spaced vertical intervals.
  • 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.
  • said second support means further includes a header support base mounted on said at least one mounting plate.
  • 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.
  • V-slide assemblies include a baseplate slidable along said longitudinal trackway, a standard extending outwardly from said baseplate, 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.
  • said retention means is an adjustable cable means entrained about said baseplate and fixed at its ends to said base 9.
  • 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.
