Definitions

  • the invention also relates to a drilling machine which can be used for extracting and inserting a drilling rod into the tap hole of a shaft furnace, comprising a working tool with a coupling means at the end. free from the rod and movable along a carriage bearing on the wall of the oven, a clamp mounted on the carriage, in axial alignment with the coupling device and movable longitudinally with respect to the carriage, under the action of a hydraulic cylinder mounted thereon, characterized in that said clamp is a bi-directional clamp acting under the action of a pneumatic or hydraulic fluid, either in one direction or in the opposite direction.
  • the invention also relates to a bi-directional clamp designed for such a machine and comprising two pairs of jaws arranged symmetrically around an axial channel capable of receiving a piercing rod, and displaceable obliquely with respect to said channel, the pair of jaws on the furnace side being oriented towards the front for the extraction of the rod and the pair of jaws on the opposite side being oriented towards the rear for the introduction of the rod.
  • the clamp comprises two pairs of jaws, arranged in a cross, in the same housing block, the two jaws of each pair being arranged symmetrically around an axial channel of the housing block and displaceable obliquely relative to to said channel, one of the pairs of jaws being oriented towards the front for the extraction of the rod and the other pair of jaws being oriented towards the rear for the introduction of the rod.
  • the rod 22 When the rod 22 extends to the front end of the mount, it is preferable, so as not to have to thread it axially through the clamp, to use an open clamp as described below, in order to be able to engage the rod laterally in the clamp.
  • an open clamp As described below, in order to be able to engage the rod laterally in the clamp.
  • the clamp 46 On the other hand, if the rod 22 is shorter, or the carriage longer, it is possible to completely advance the clamp 46, to engage the rod 22 in the mandrel 36, to place it, in cantilever , on the support 38 and engage the clamp 46 axially, moving back, around the rod, the clamp can, therefore, be a closed clamp.
  • the carriage 26 With the wall of the furnace 20.
  • the lock 40 it suffices to manually engage or by an automatic system the lock 40 to ensure the male connection and female at the support 40. This locking makes it possible to absorb the counter-reaction forces to the right when the rod 22 is pressed under the action of the jack 42.
  • the latch 40 is raised to release the support 34 from the wall of the oven and to be able to withdraw the machine towards the garage position and abandon the rod 22 in the position according to FIG. 4.
  • FIG. 11 shows an axial view of a clamp 70 according to FIG. 10.
  • the clamp 70 is fixed, for example screwed, on a shoe 80 actuated by the rod 44 of the piston 42 (FIG. 1) and intended to slide between two beams 26a, 26b forming the mount 26.
  • the jaws are provided above and below the channel 76 which opens by a groove 88 to the side.
