Definitions

  • This invention relates to a flange aligning tool.
  • each flange is provided with one or more bolt holes for receiving connecting bolts.
  • flanges When flanges are to be connected together, they are positioned in face to face engagement with corresponding bolt holes in the flanges registering with each other to receive the connecting bolts ;
  • the present invention seeks to provide a flange alignment tool which facilitates alignment of two flanges which are to be bolted together such that the bolt holes therein are brought into registration with each other.
  • the flange aligning tool facilitates the alignment of the bolt holes of two flanges so that the flanges may be easily secured together.
  • the flange aligning tool will also assist in aligning any other item, such as a spacer plate, which may be required to be located between the two flanges.
  • each shank section is of circular cross section.
  • the differing transverse dimensions of the shank sections are provided by different diameters of the circular shank sections.
  • a transition region is provided between adjacent shank sections.
  • the rotation means may comprise a head formation adapted to be engaged by a tool for rotating the shank.
  • the head formation may be of hexagonal configuration so as to be readily engagable by a tool such as a spanner.
  • the end section of the shank opposite the rotation means may taper inwardly to facilitate insertion of the shank into flange bolt holes.
  • Each shank section may be larger in diameter than the adjacent shank section closer to the end section.
  • a projecting portion is provided between the rotation means and the shank section adjacent the rotation means to prevent the alignment tool passing completely through the flange bolt holes.
  • each flange aligning tool manoeuvred into two corresponding holes in flanges which are to be aligned.
  • the flange aligning tools are then rotated. Because the shank sections of each tool are aligned at their periphery with a edge extending longitudinally along the shank, rotation of the shank draws the two holes in which the shank is received into registration with each other. This then allows other corresponding holes in the two flanges to move into registration so that bolts can be inserted into those other holes.
  • Each flange aligning tool can then be removed and replaced by a further bolt, so completing the process of bolting the flanges together.
  • Figure 1 is a side view of a flange aligning tool according to the embodiment
  • Figure 2 is a plan view of the flange aligning tool
  • Figure 3 is an end view of the flange aligning tool
  • Figure 4 is a perspective view illustrating the flange aligning tool about to be inserted into two corresponding holes in flanges which are to be brought into alignment;
  • Figure 5 is a perspective view similar to Figure 4 illustrating the flange aligning tool in position in the two corresponding holes, with a bolt being shown in readiness to be inserted into another pair of corresponding holes in the flanges.
  • the embodiment shown in the drawings is directed to a flange alignment tool 10 for aligning two flanges 1 1 , 12 such that bolt holes 13 in one flange are brought into registration with corresponding bolt holes 13 in the other flange to receive bolt assemblies 15 for bolting the flanges together.
  • the bolt assemblies 15 comprise a bolt 17 and a nut 19.
  • the flanges 1 1 , 12 are provided at the ends of pipe sections 21 such that the pipe sections are connected one to another by way of the flanges.
  • the flange aligning tool 10 comprises a shank 23 having a tapered end section 25 at one end thereof and a head 2J provided at the other end thereof.
  • the head 27 is configured as a block formation having side faces 29 engagable by a tool such as a spanner, not shown, to allow the shank 23 to be rotated about its length.
  • the shank 23 includes a plurality of shank sections 30, there being four such shank sections in this embodiment identified by reference numerals 30a, 30b, 30c and 30d.
  • Each shank section 30 is larger in diameter than the adjacent shank section 30 closer to the tapered end section 25.
  • the diameter of shank section 30d is smaller than 30c, which is smaller than 30b which is smaller than 30a.
  • the shank sections 30 are aligned at their periphery to define a staright edge extending longitudinally along the shank 23, and identified by reference numeral 35 in Figures 1 and 3 of the drawings.
  • a transition region 37 is provided between adjacent shank sections 30.
  • the flange aligning tool of this embodiment is provided with the four shank sections 30a, 30b, 30c and 30d in order to accommodate flanges with bolt holes 13 of various diameters. In any particular application, only two adjacent shank sections 30 would be used.
  • the flange aligning tool is also comprises a projecting portion 38 provided between the head 27 and the shank section 30a so as to prevent the alignment tool passing completely through the flange bolt holes 13.
  • two flange alignment tools 13 are typically used (although only one such tool is shown in Figures 4 and 5).
  • the flanges 11 , 12 are to be aligned, it is necessary to move the flanges into abutting relationship with the holes 13, which are to be moved into registration with each other, in approximate alignment so as to permit insertion of each flange alignment tool 10 into two corresponding holes.
  • the one tool 10 is then inserted and the other tool 10 is inserted into another set of two corresponding holes.
  • Each flange alignment tool 13 is introduced into its respective set of two holes with end section 25 thereof entering first.
  • each flange alignment tool 10 is in position in the respective set of two holes 13, one shank section 30 is accommodated within one of the holes and an adjacent shank section 30 is accommodated in the other hole.
  • shank section 30b is accommodated within the hole 13a within flange 12.
  • shank section 30a is accommodated within the corresponding hole 13 in flange 11.
  • Rotation of the shank 23 causes the two holes 13 to move into registration with each other. This occurs because of the alignment of the shank sections 30 at the periphery thereof; that is, because of the straight edge 35.
  • the action of aligning the two holes in which the flange aligning tool 10 is accommodated serves to bring other holes 13 in the flanges 11 , 12 into alignment so as to permit insertion of bolt assemblies 15 into those other holes.
  • each flange alignment tool 10 can be rotated (typically about one quarter of a turn) to free it from frictional engagement within the aligned holes 13.
  • the flange aligning tool 10 can then be removed and replaced by a bolt assembly 15 so as to complete bolting of the flanges 11 , 12 together.
  • the present invention provides a simple yet highly effective tool for aligning flanges which are to be bolted together.

Abstract

L'invention se rapporte à un outil (10) permettant d'aligner des brides comprenant une tige (23) ayant au moins deux segments (30) de tige, chaque segment (30) étant aligné sur le pourtour des segments adjacents (30) de tige afin de délimiter un bord droit (35) s'étendant longitudinalement le long de la tige (23), lesdits segments (30) ayant des dimensions différentes dans un sens transversal en direction dudit bord (35). L'outil (10) permettant d'aligner des brides comprend également un organe de rotation sous forme de tête (27), placée à l'extrémité de la tige (23) pour assurer une rotation sélective de la tige (23) autour d'un axe longitudinal. Selon un mode de réalisation, l'outil (10) permettant d'aligner les brides est utilisé pour aligner des brides (11, 12) de manière que les trous de passage (13) pratiqués sur une bride correspondent aux trous de passage (13) pratiqués sur l'autre bride afin d'y insérer des boulons (15) permettant le boulonnage des brides.
