Definitions

  • the invention relates to a solution for ensuring occupational safety in drilling equipment equipped with a drilling mast. It relates to the protection of persons, in particular, from contact with parts moving on and / or within the drilling mast.
  • the preferred field of application of the invention is the implementation of a corresponding protection for top hammer drilling machines and down-hole drilling machines, without, however, the invention being restricted to this.
  • the invention relates generally to drilling devices which have a drilling mast in or on which rods or pipes are guided with a drilling head arranged at their end, the drilling head being able to be designed very differently depending on the intended use.
  • the drilling mast is arranged, for example, on the boom of an excavator (or crane), which is used for positioning and aligning the drilling mast and thus the drilling tool. It is also common to arrange the drilling mast on a mount that is not self-propelled but can be moved by means of a suitable vehicle, with structures for positioning and aligning the drilling mast.
  • Drilling equipment with a drilling mast such as in particular drilling equipment of the aforementioned type, namely top hammer drilling equipment and downhole drilling equipment, is used, for example, to drill holes in rocks or rocks, for example for blasting in quarries or to produce supply shafts.
  • a rotation about their longitudinal or central axis or / and - as in the case of the hammer drill - perform an up and down movement due to a periodic loading with a preferably hydraulically generated one, depending on the drilling principle used, within the drilling mast or on the drilling mast Force.
  • a number of other moving parts are often arranged on a corresponding drilling mast, such as a storage magazine for automatic tracking of rods or pipes for extending the drilling tool.
  • Another disadvantage is the considerably poorer accessibility of individual machine parts when carrying out service and maintenance measures or when changing the drilling tool (changing the drilling head or parts of the drill pipe). Furthermore, it is to be regarded as disadvantageous that the drilling of soil in the immediate vicinity of walls or rock or rock elevations is made difficult or even impossible due to the enlargement of the diameter of the drilling mast resulting from the arrangement of the cage. In addition, it can damage the drill pipe, for example, when it breaks Cages come, so that their replacement is required, which entails corresponding costs.
  • GB 2 479 749 A1 describes a safety device for drilling rigs equipped with a drilling mast, in which an optically based, namely an opto-electronic system is used to detect a person staying in the effective range of the drilling mast and thus in the danger zone.
  • an optically based namely an opto-electronic system is used to detect a person staying in the effective range of the drilling mast and thus in the danger zone.
  • this is a lidar system working with laser light. If a person is detected in the danger zone using this optical system, the protective device generates a switch-off signal which disables the drilling device.
  • a radiation source to be carried and coupled to one another is ensured that only signal transmitters can stay in the work area surrounded by the barrier and also due to the absence of a transmission signal a defect or by dropping a radiation source carried by one of the people in the work area can be reacted to accordingly.
  • this system is comparatively complex.
  • the object of the invention is to avoid the aforementioned disadvantages and to overcome the problems indicated.
  • an alternative solution is to be specified which can be implemented with little effort, but which also guarantees a high degree of reliability and thus safe occupational safety even under the harsh operating conditions of the drilling equipment.
  • a method and a device suitable for carrying out the method are to be provided.
  • the protection of persons from contact with parts moving on and / and within the drilling mast of a generic drilling device is ensured in that the moving parts to be secured with regard to avoiding contact in the event of an intrusion Subject or object are put out of operation in a scanning field spanned by several sensors around the drilling mast.
  • This scanning field is using several radar sensors clamped, which are arranged on the drill to be secured.
  • radar sensors are used, which are designed to emit radar radiation and to receive radar radiation reflected from a subject or object located in the scanning field.
  • These radar sensors are arranged on the drilling device, preferably on the drilling mast, and are oriented in such a way that the radar radiation emitted by them is so observed that their respective main beam lobe does not cover the drilling surface or parts of the drilling mast.
  • the sensor field or scanning field refers to the spatial area which, by superimposing the radiation fields (without or with consideration of the radiation side lobes already mentioned) of all respectively activated radar sensors, is to be detected for the intrusion or the entry of a subject or object, in order, if necessary, to automatically deactivate moving objects To effect parts of the drill.
  • an essential feature of the proposed solution is the use of radar sensors to generate the sensory field.
  • optical sensors have proven to be unsuitable for this purpose for the reason already mentioned that strong dust formation occurs during drilling. This also applies to the use of appropriate infrared-based sensors. But also the use of ultrasonic sensors has so far proven to be impractical. The way they function is also impaired or disturbed too much by the formation of dust.
  • the radar sensors it is essential to use the radar sensors to span a scanning field around the drilling mast in such a way that at least none of the main radiation lobes of the radar beams emitted by the radar sensors sweep over the drilling surface or parts of the drilling mast.
  • the latter is important insofar as it has been shown that otherwise reflections of the radar beams occur on the drilling surface and / or on the drilling mast, which falsify the result of the evaluation of radar beams possibly arriving at the radar sensors. Accordingly, radar beams arriving at the radar sensors should only be detected if they are reflected by an obstacle in the vicinity of the drilling mast, namely in particular a person or a body part of a person.
  • the radar sensors are therefore preferably on the drilling mast, but not - as is obvious - when their radiation fields are aligned along the drilling mast in the direction of the drilling surface, mounted on the end of the drilling mast facing away from the drilling surface. Rather, in the case of their preferred direct arrangement on the drilling mast, the radar sensors are arranged on the end of the drilling mast facing the drilling surface.
  • the aforementioned condition according to which at least the main radiation lobes of the emitted radar beams neither sweep over the drilling surface nor parts of the drilling mast, by achieving that the radiation axes of the radar beams emitted by the radar sensors and generating the scanning field are aligned in a radially projecting manner with respect to the longitudinal axis of the drilling tool.
  • Compliance with the conditions mentioned is achieved by a corresponding arrangement of the radar sensors on the drilling mast or the drilling device or / and by their corresponding alignment and, if appropriate, moreover by a corresponding selection of the radar sensors with regard to the opening angle of the radar beams emitted by them.
  • the radar sensors are arranged on the drilling mast of the drilling device at a distance based on the average height of a person from the end facing the drilling surface.
  • the drilling mast of the drilling device for example for producing a bottom hole
  • the radiation axes of the radar beams emitted by the radar sensors and generating the scanning field are preferably aligned essentially horizontally, as already explained, by appropriate arrangement and / or alignment of the sensors themselves.
  • a further possibility of complying with the boundary conditions mentioned above with regard to avoiding undesired reflections is to align the radiation axes of the radar beams emitted by the radar sensors in the opposite direction to the drilling direction in such a way that they run parallel to the longitudinal axis of the drilling tool or an imaginary one around this longitudinal axis. span the conically opening envelope surface.
  • the radiation axes of the emitted radar beams are accordingly aligned in such a way that they run counter to the drilling direction and parallel to the longitudinal axis of the drilling mast or at an angle with respect to this longitudinal axis on its side facing away from the drilling surface.
  • the radar sensors are also in this Case on the end of the drilling mast facing the drilling surface, that is to say arranged on the side of the drilling head, and at the smallest possible distance therefrom, so that their radiation fields run as far as possible along the entire axial extension of the drilling mast, with an arrangement of the radar sensors also in this connection at a distance of 0.50 m to 1.50 m from the drilling surface (from the surface into which the hole is to be drilled).
  • the radiation axes of the radar beams emitted by the radar sensors are aligned at least in the case of a horizontal alignment of the drilling mast to produce a horizontal bore in the manner described above.
  • the drilling tool is understood to mean the drilling head and the boring bars connected or connected to it, or the drilling pipes connected or connected to it, at the end of which the drilling head is arranged.
  • the occupational health and safety procedure for decommissioning the moving parts in the event that a person or a body part of a person gets into a sensor field or scanning field generated around the drilling mast, can be configured as follows.
  • the radar beams spanning the sensor field are arranged at the appropriate height (as already stated, based on the height of a person) so that their radiation axes are horizontally outwards in relation to the drilling mast run directed.
  • the drill is used to make a horizontal hole an alignment of the radiation axes opposite to the drilling surface and, as already shown as a basic design option, parallel to its longitudinal axis or slightly towards the longitudinal axis, that is to say inclined away from it.
  • the radiation axes of the emitted radar radiation in the manner described first, i.e. radially to the drilling mast, and when this specified angle is exceeded up to a horizontal alignment of the longitudinal axis of the drilling tool or the drilling mast, the radiation axes are aligned according to the second possibility explained.
  • this can be achieved in that the respective orientation of the drilling mast, i.e. its respective angle with respect to the vertical or the horizontal direction, is detected by means of a movement or inclination sensor and, depending on this, a switchover between the two variants of the orientation of the Radar beams are automated.
  • the angle to be set for switching between the two explained variants of the beam alignment is, in view of the fact that, in particular when a vertical hole is drilled, the drilling surface (in this case the drilling base or the floor) must be avoided, especially depending on the opening angle of the radar sensors emitted radar radiation and the range of the beams. If, in the case of radar sensors of shorter range and in the event of an inclination of the drilling mast, the radiation axis of the emitted beams only touches the drilling surface due to the short radiation range, this is unproblematic with a view to avoiding undesired reflections.
  • the radar beams have a relatively large opening angle and at the same time a long range, a switch to the other operating mode, with radiation axes running in the axial direction of the drilling mast, should take place sooner. so already at an angle smaller than the vertical.
  • the angle to be set for the switchover should preferably be between 15 ° and 25 ° relative to the vertical.
  • a respective alignment of the radar beams or their main axes can be achieved by an appropriate arrangement of the radar sensors on the drilling device and / or by a corresponding alignment of the radar sensors themselves arranged on the drilling device.
  • the arrangement of the radar sensors should preferably be based on their arrangement directly on the drilling mast.
  • second sensor group could be used to generate a sensor field by means of radar beams, the radiation axes of which in the opposite direction to the drilling surface and in the axial direction with respect to the drilling mast, namely parallel to the longitudinal axis of the drilling tool or preferably at a slight angle of inclination of removing the longitudinal axis are aligned.
  • Another possibility is to use only one sensor group, the sensors being arranged on the drilling mast in such a way that they themselves can be aligned differently or moved into different positions. This can preferably be done automatically by means of actuators to be controlled accordingly.
  • the solution presented could meet the occupational safety requirements in the event of a horizontal alignment of the drilling mast (for example for the purpose of drilling a horizontal hole in a wall) as well as in the case of vertical drilling by means of a radial alignment of the radiation axes of the sensor field, which is relative to the longitudinal axis of the drilling tool Radar beams can be reached.
  • radar sensors would have to be arranged preferably at several locations of the drilling mast over the entire axial extent of the drilling mast, in which the main axes of the radar beams emitted by them are radially aligned accordingly.
  • radially radiating radar sensors which are preferably attached to the drilling mast at a height which is based on the average human body height (slightly below the waist to about chest height, that is to say preferably about 80 cm to 150 cm), offers a number of advantages . This enables them to cover a larger danger area around the drilling mast or to better adjust the size of this danger area. With their help, it is also fundamentally easier to avoid possible reflections of the radar beams on the drilling mast itself.
  • a device which accomplishes the task and is suitable for carrying out the method is characterized in that a plurality of radar sensors spanning a sensory scanning field are arranged on the drilling rig, preferably on its drilling mast, which are designed both to emit radar radiation and to emit radiated radiation subject or object located in the scanning field to receive reflected radar radiation.
  • the radar sensors in question are arranged and aligned and, if necessary, selected with regard to the opening angle of the radar beams emitted by them, so that at least none of the main radiation lobes of the radar beams emitted by the radar sensors sweeps over the drilling surface or parts of the drilling mast.
  • the device has a first group of radar sensors for this purpose, in which the radiation axis of the radar beams emitted by them radially from the longitudinal axis of the drilling tool is aligned away.
  • a second sensor group can be provided which, in contrast, is arranged and / or aligned such that the main axis or radiation axis of the radar beams emitted by them runs in the opposite direction to the drilling direction and parallel to the longitudinal axis of the drilling tool or slightly inclined away from this longitudinal axis.
  • the drilling device can advantageously be developed in such a way that depending on the angle of inclination of the drilling mast - if two sensor groups are provided - one or the other sensor group is automatically activated or that the sensors themselves can be automatically aligned differently depending on the angle of inclination of the drilling mast.
  • the drilling device has at least one inclination or motion sensor.
  • the processing unit provided anyway (in terms of its hardware and software equipment) is designed such that it is suitable for evaluating the sensor signals of the at least one inclination or motion sensor.
  • the processing unit must also switch the drilling device depending on the angle of inclination of the drilling mast against the vertical determined by the sensor signals by aligning all or part of the radar sensors with the aid of an actuator or by activating part of the radar sensors and deactivating another part of the radar sensors to cause the previously explained operating modes of the drilling device which differ with regard to the alignment of the radiation axes of the emitted radar beams.
  • this can also be equipped with a so-called override function.
  • This function enables an operator of the drilling machine to automatically stop or shut down the moving parts of the drilling machine to prevent when a subject or object (in particular object, but exceptionally also a subject) is in the sensor field or gets into it, provided the operator recognizes that there is no actual danger.
  • This can be useful, for example, if an object is blown into the sensor field by wind, for which the occupational safety measures do not have to apply.
  • the moving parts of the drilling device would be put out of operation after a detection of an object in the sensor field with a slight delay (approx. 0.5 seconds - 1 second) and an alarm signal would be triggered first, after the operator had perceived it activate the override function, i.e. could interrupt the automated decommissioning of the moving parts.
  • the solution according to the invention also offers the possibility of a more flexible handling compared to the prior art with mechanical protection (cage) when introducing a vertical hole in the immediate vicinity of a wall or a horizontal hole near the floor.

  • This type of alignment which is preferably provided for the application of making a vertical bore (drilling direction b corresponds to the vertical v) by means of the drilling tool (not shown) held on the drilling mast 1, ensures that at least the main radiation lobes 8 (see again Fig. 5 ) - Depending on the opening angle 10 of the emitted radiation, possibly also the radiation side lobes 9, 9 '- do not paint over the drilling surface 4, namely, for example, the ground into which the vertical bore is to be made.
  • the radar beams in an imaginary extension will only touch the ground at a large distance from the drilling mast 1 and will be reflected here, this being theoretical insofar as the beams reach the corresponding point of contact with the ground due to the finite range of the radar sensors 2 1 - 2 n preferably not reach at all.
