Definitions

  • the object of the invention is to take this into account and to design drilling devices of the type mentioned in such a way that the initiation of free-fall operation of a winch is at least so difficult in terms of operation that increased safety results.
  • the invention also strives for a cheap design of safeguards against inadmissible free-fall operation in detail. Further problems connected with all of this, with which the invention is concerned, result from the respective explanation of the indicated solution.
  • the invention provides that in addition to an element to be actuated by the operator of the drilling device for bringing about the free-fall operation, at least one safety switching element is present in a control line for a control element or in a switching line, and a predefinable position of the safety switching element is a prerequisite for this an activation of the control member for the state "free fall operation". This makes it possible to meet security requirements to a limited extent or to a large extent as required.
  • a free fall activation of a winch e.g. 1, prevents the winch 10 of the drilling device as long as the upper part 3 of the drilling device is rotated in one direction or the other.
  • a directional control valve 30 is provided for influencing the winch.
  • a line valve 48 is connected to lines 43 and 44, to which a pressure switch 47 is connected via line 49 and is arranged in control line 34, 31 for valve 30.
  • the pressure switch 47 can, for example, be designed such that it is normally closed and responds at a control pressure of approximately 1 bar in the line 49 and then interrupts the control line 34, 31 by opening the contact. Actuation of the push button 35 then has no effect, i.e. the winch cannot be brought into the free-fall state as long as the upper part 3 of the drilling device rotates. If the control pressure drops again at the end of the rotary movement, the switch 47 can close again.
  • a push button switch 37 can be provided in the control line 34, 31 as an additional safety switching element. The explanations for the embodiment according to FIG. 6 apply accordingly.
  • FIG. 11 Another embodiment is shown in FIG. 11.
  • the two pressure switches 67 and 77 are arranged in a control line 34, which branches into the lines 31 and 33 leading to the valves 30 and 32, as was also explained in connection with FIG. 6.
  • the control line 34 is interrupted when one of the pressure switches 67 and 77 opens or when both open at the same time, as is the case when both motors 61 and 71 are in operation to move the drill.
