Definitions

  • a drilling table for soil drilling equipment comprises a rotatable carrier device for a drill rod, and means for rotating the carrier device, damping means being provided at an upper surface of the carrier device and rotatable therewith for imparting rotary movement to the drill rod when carried by said damping means.
  • the present invention relates to drilling tables for soil drilling equipments, and more specifically to such drilling tables in which the drive and necessary gears for a drill rod are accommodated.
  • a drilling table for soil drilling equipments comprising damping means at an upper surface provided for bearing a flange at the upper end of a drill rod.
  • the damping means may comprise a ring retained within a groove of dovetailed cross section in the surface.
  • the damping means may comprise a ring loosely retained within a groove of double trapezium cross section in the surface.
  • the damping means may comprise a plurality of segments each retained within a recess of dovetailed cross section within the surface.
  • FIG. 1 shows a view, partly in section, of a drilling table embodying the invention
  • FIG. 2 shows a sectional view of a detail of an alternative embodiment
  • FIG. 3 shows a plan view of a detail of yet a further embodiment.
  • FIG. 1 comprises a drilling table 3 mounted to be vertically slidable on a guide post 1 of a soil drilling equipment.
  • Hydrostatic gearing 4 drives a drill rod 7 suspended by a rope 2 via a gear rim 5, which is born in a ball bearing 14, and via a carrier device comprising a carrier 6, and a damping ring 9 which is retained in a dovetaillike groove 10 in an intermediate ring 11.
  • a flange 8 is provided at the upper end of the drill rod 7 and prevents the drill rod 7 falling through the drill table. The flange 8 rests on the damping ring 9.
  • FIG. 2 illustrates an alternative embodiment, in which the damping ring 9 is of double trapezium shape and smaller in cross section than a guide groove 12 in an a intermediate ring 11'.
  • the damping ring 9 is thus loosely retained in the guide groove 12 and may therefore wander. It is thereby avoided heat that, for example, uneveness at the flange 8 of the drill rod 7 always strikes the same spot on the damping ring and thereby wears it out prematurely.
  • FIG. 3 shows yet a further embodiment in section along the line III-III of FIG. 1,
  • damping segments 13 are employed instead of a damping ring 9 or 9.
  • the damping segments 13 are fastened as hereinbefore described with reference to FIG. 1 in a groove 10 of dovetailed cross section in the intermediate ring 1 l.
  • a drilling table for a soil drilling equipment comprising a rotatable carrier device adapted to drive a drill rod having a collar at the upper end of the drill rod, said carrier device havmg an upper surface rotatable therewith, means for rotating said carrier device and said upper surface, and damping means being arranged at said upper surface to carry said drill rod collar when said drill rod is driven by said carrier device.
  • damping means comprise a damping ring retained within a groove of dovetailed cross section in said carrier device.
  • damping means comprise a damping ring loosely retained within a groove of double trapezium cross section in said carrier device.
  • damping means comprise a plurality of segments each retained within a groove of dovetailed cross section within said carrier device.
