Definitions

  • FIG. 1 is a perspective view of a clamping tool.
  • the clamp assembly 12 includes a clamp base 18.
  • the clamp base 18 is a rigid structural element having a clamp base opening 15 defined therein.
  • a pair of moveable jaws 17 are defined by a moveable mandrel block 20 and a moveable rotating sleeve 22.
  • the opposing moveable jaws 17 are caused to remain parallel to one another when opening and closing. This prevents the pipe to be clamped from sliding out of or away from the jaws 17.
  • it becomes easier to clamp the pipe because the jaws 17 are positioned on opposite sides of the pipe and the force is equally applied to the pipe in a direction that is generally normal to the abutting surfaces of the jaws 17.
  • the clamping tool 10 will be brought into position in a direction normal to the pipes axial length.
  • the link extensions 40, 42 keep the pipe properly poisoned and the arrangement of the jaws 17 generally prevent the tool from moving off of the pipe and prevent the pipe from moving out of the jaws 17 in cases where such movement might be possible. Since the link extensions 40, 42 are coupled to the top links 31 , 24, the link extensions will be moved out of the way and into the position illustrated in FIG. 3 as the jaws 17 are closed. To close the jaws 17, adjusting links 44, 46 are retracted into clamp base
  • FIG. 5 illustrates the handle 16 as it is coupled to the threaded rod 64.
  • An angled bar 82 may be attached to the extension tube 14.
  • the angled bar 82 includes a lower locking hole 84 that can be aligned with an upper locking hole 86 bored through handle 16.
  • a locking member such as a padlock or any securing member can be passed through both holes 84, 86 and essentially lock the clamping tool 10.
  • the clamping tool 10 is locked after a pipe has been sealed, the lock will prevent the clamping tool 10 from accidentally or unintentionally being opened.

Abstract

L'invention porte sur un outil permettant de serrer des tuyaux de façon à empêcher l'écoulement du fluide, cet outil comprenant des mâchoires restant parallèles. On peut faire tourner une poignée pour ouvrir et fermer l'outil de serrage. Un manchon rotatif permet de déterminer sélectivement la largeur de l'intervalle à l'état fermé de l'outil. Un positionneur de tuyau positionne correctement le tuyau entre les mâchoires.
