Abstract
This invention relates to a bolt-type boiler wall tube tool in which boiler tubes in the form of a wall can be clampingly secured to retain adjacent ends of the boiler tubes forming the wall in aligned relation when connecting the ends of the boiler wall tubes by welding.
Claims11
A boiler wall tube tool comprising a pair of opposed clamp members with each clamp member including at least one recess therein to engage adjacent ends of a boiler wall tube on opposite sides of a juncture between the adjacent ends, means moving the clamp members towards each other for secure clamping engagement with adjacent ends of the tube for maintaining them in alignment while connecting the ends of the tube by welding, each clamp member including means providing access to the periphery of the juncture between the ends of the tube clamped by the clamp members, said means moving the clamp members towards each other including bolt means connecting said clamp members for moving the clamp members towards each other and enabling the clamp members to be moved away from each other and to be separated, said bolt means including a headed bolt having a threaded end portion, one of said clamp members including a threaded bore extending therethrough for treadably receiving the threaded portion of the bolt with the headed end of the bolt engaging the other clamp member to enable the clamp members to be securely clamped to the adjacent ends of the tube to retain the adjacent ends of the tube in secure alignment, each of said clamp members having a pair of recesses therein receiving adjacent ends of a pair of boiler wall tubes, said bolt means including a single bolt extending centrally through said clamp members and between the pair of boiler wall tubes at the juncture between adjacent ends of the boiler wall tubes.
A boiler wall tube tool comprising a pair of opposed clamp members with each clamp member including at least one recess therein to engage adjacent ends of a boiler wall tube on opposite sides of a juncture between the adjacent ends, means moving the clamp members towards each other for secure clamping engagement with adjacent ends of the tube for maintaining them in alignment while connecting the ends of the tube by welding, each clamp member including means providing access to the periphery of the juncture between the ends of the tube clamped by the clamp members, said means moving the clamp members towards each other including bolt means connecting said clamp members for moving the clamp members towards each other and enabling the clamp members to be moved away from each other and to be separated, said bolt means including a headed bolt having a threaded end portion, one of said clamp members including a threaded bore extending therethrough for threadably receiving the threaded portion of the bolt with the headed end of the bolt engaging the other clamp member to enable the clamp members to be securely clamped to the adjacent ends of the tube to retain the adjacent ends of the tube in secure alignment, each of said clamp members having a single recess therein receiving adjacent ends of a single boiler wall tube, said bolt means including a pair of bolts extending centrally through said clamp members and between adjacent boiler wall tubes at the juncture between adjacent ends of the pair of boiler wall tubes.
In combination with a boiler tube wall formed by a plurality of closely spaced tubes rigidly connected by webs, a tool for clampingly engaging adjacent ends of a tube from which the connecting webs have been removed and retaining the adjacent tube ends in alignment while being connected by welding, said tool comprising a pair of opposed clamp members with each clamp member including recess means therein to engage adjacent ends of at least one boiler wall tube on opposite sides of a juncture between the adjacent tube ends, means moving the clamp members towards each other for secure clamping engagement with only the adjacent ends of the tube for maintaining them in alignment while connecting the ends of the tube by welding, each clamp member including means providing access to the periphery of the juncture between the ends of the tube clamped by the clamp members, said means moving the clamp members towards each other including bolt means extending between the tubes in the areas from which the webs have been removed.
The combination as defined in claim 10 wherein each of said clamp members includes a single recess means extending longitudinally on the inner surface thereof, said bolt means including a pair of bolts extending through the clamp members with the bolt having a head at one end and a threaded portion at the other, the inner clamp member including threaded bores in threaded engagement with the bolts to enable a power wrench to engage the head of the bolts for tightening and loosening the clamp members, said means providing access to the juncture between the ends of the tube including a centrally disposed opening in each of said clamp members in alignment with the juncture between the adjacent ends of the tube to enable access to a substantial portion of the periphery of the adjacent ends of the tube for welding.
A boiler wall tube tool comprising a pair of opposed clamp members with each clamp member including a pair of longitudinal recesses therein to receive and engage adjacent ends of a pair of boiler wall tubes on opposite sides of a juncture between the adjacent ends, bolt means moving the clamp members towards each other for secure clamping engagement of the adjacent ends of a pair of boiler wall tubes for maintaining them in alignment while connecting the ends of the tubes by welding, each clamp member including means providing access to the periphery of the juncture between the adjacent ends of the pairs of tubes clamped by the clamp members, said bolt means including a single bolt extending centrally through said clamp members and between the pair of boiler wall tubes at the juncture between adjacent ends of the boiler wall tubes, said means providing access to the periphery of the juncture between the adjacent ends of the tubes including a laterally inwardly extending centrally disposed recess in each side edge of each clamp member in alignment with the juncture between the adjacent ends of the pair of tubes thereby providing access to a substantial portion of the periphery of the adjacent ends of the pair of tubes both interiorly and exteriorly of the boiler wall formed by the tubes, the headed end of the single bolt engaging the outer clamp member thereby rendering the head of the bolt available for engagement by a wrench exteriorly of the boiler wall formed by the tubes.
A boiler wall tube tool comprising a pair of opposed clamp members with each clamp member including a single recess therein to engage adjacent ends of a boiler wall tube on opposite sides of a juncture between the adjacent ends, bolt means moving the clamp members towards each other for secure clamping engagement of the adjacent ends of the boiler wall tube for maintaining them in alignment while connecting the ends of the tube by welding, each clamp member including means providing access to the periphery of the juncture between the adjacent ends of the tube clamped by the clamp members, said bolt means including a pair of bolts extending centrally through said clamp members and between adjacent boiler wall tubes at the juncture between adjacent ends of the boiler wall tube, said means providing access to the periphery of the juncture between the adjacent ends of the tube including a centrally disposed opening in each clamp member in alignment with the juncture between the adjacent ends of the tube thereby providing access to a substantial portion of the periphery of the adjacent ends of the tube both interiorly and exteriorly of the boiler wall formed by the tubes, the headed end of the pair of bolts engaging the outer clamp member thereby rendering the heads of the bolts available for engagement by a wrench exteriorly of the boiler wall formed by the tubes.
