Definitions

  • the present invention relates to loading drill rods from a cassette to a drilling position in a rock drilling machine
  • rock drilling rigs are used for drilling bore holes on rock surfaces.
  • the rock drilling rig comprises one or more drilling booms which are provided with drilling units.
  • drill holes having a greater length than one drill rod need to be drilled.
  • two or more drill rods need to be connected to each other in order to form an extension rod.
  • several drill rods are stored in a rod cassette which is arranged in the drilling unit.
  • the rod cassette becomes large and heavy, whereby it may hamper the drilling.
  • the size of the rod cassette can be smaller, but the re-loading the rod cassette can occur frequently which decreases the operational efficiency of the drilling unit.
  • US5556253 A discloses an automatic pipe loading device including a magazine containing a plurality of pipes which are gravity fed through a discharge opening at a discharge end of the magazine.
  • a pipe transfer member is mounted beneath the magazine and rotates between load and unload positions. In a load position, the pipe transfer mechanism presents a pocket in alignment with a discharge opening of the magazine. In all other positions, the pipe transfer mechanism presents a blocking surface preventing pipes from being discharged from the magazine.
  • the pipe transfer member includes a pipe grip for grasping a pipe received within the receiving pocket and releasing the grasped pipe at a desired location.
  • US 2014/186143 A1 discloses a pipe handling device configured to remove pipe sections from a storage pod carousel assembly. An index arm assembly is used to move individual drill pipe sections to and from the storage pod carousel assembly directly to the rotary drive unit's centerline of drilling position.
  • An object of the present invention is to provide an apparatus, a cassette for drill rods and a rock drilling machine so as to alleviate some of the above disadvantages.
  • the objects of the invention are achieved by an apparatus, a cassette and a rock drilling machine which are characterized by what is stated in the independent claims.
  • the preferred embodiments of the invention are disclosed in the dependent claims.
  • Some embodiments provide loading rods from a cassette and an external source by a single loading arm.
  • Figures 1a to 1d illustrate an apparatus 100 having a loading arm 102 according to an embodiment.
  • the apparatus is capable of loading drill rods 104 from a cassette 106 to a Drilling Position (DP) in a rock drilling machine by the loading arm.
  • the loading arm may be a longitudinal structure extending parallel to the cassette and the rods in the cassette.
  • the loading arm is capable of receiving at least one rod and attaching to the rod for moving the rod in and/or out of the cassette.
  • rods may be connected to a tool for drilling a hole, i.e. a drill hole, by the rock drilling machine.
  • the loading arm may be capable of movement that has a direction that is transverse to a longitudinal direction of the rods. Accordingly, the loading arm may move rods out of the cassette to the DP such that the longitudinal direction of the rods may be maintained for fast connection to the tool or other rods at the DP.
  • the movement of the loading arm is described by Figures 1a to 1d that illustrate the loading arm in different positions. It should be appreacited that the loading arm may be turned from one position to another and vice versa such that rods may be moved between various positions by the loading arm.
  • Figure 1c illustrates the loading arm in the drilling position.
  • the loading arm has two loading positions for receiving drill rods. In each position at least one drill rod may be received to the loading arm.
  • the rod received to the loading arm is attached to the loading arm, e.g. by a clamp, such that the rod may be moved between various positions by the loading arm.
  • One of the positions is a position for receiving rods from the cassette.
  • One of the positions is a position for receiving rods from an external source. This position is illustrated in Figure 1a .
  • the rods may be received on at a time through a cassette gate 108. Accordingly, this position may be referred to as a Gate Position (GP).
  • GP Gate Position
  • the rods In the position for receiving rods from the external source, the rods may be received outside the cassette. This position is illustrated in Figure 1d . This position may be referred to as an Auxiliary (AUX) Position (P), AP. In both the AP and GP the rods may be received one by one. Since the loading arm has two positions for loading rods, the single loading arm is sufficient for loading rods to the drilling position. In case the cassette is empty for rods, the loading arm can be used to re-load the cassette from outside the cassette. In loading the cassette, rods may be fed to the cassette at the GP by moving rods from the AP to the GP.
  • AUX Auxiliary
  • P Auxiliary Position
  • a loading arm 102 may be arranged pivotably on the cassette 106, whereby the loading arm can be pivotally turned between the two loading positions, GP and AP, and the DP. Consequently a rod attached to the loading arm may be moved between the GP, AP and DP.
  • a loading arm 102 may be arranged pivotably on the cassette 106 and the loading arm can be turned at least 90 degrees, preferably 100 to 180 degrees, even more preferably over 180 degrees, for example 270 degrees, between the two loading positions.
  • the loading arm may be turned from one position to another and vice versa.
  • This provides freedom to installing cassettes to rock drilling machines. The greater the angle between the AP and the GP is, the more freedom is provided to the position of the GP and the position of the cassette with respect to the AP. Accordingly, the cassette may be installed into a rock drilling machine to a position, where the distance between the AP and the GP. In such a case a large angle between the AP and the GP may provide that the AP is easily reachable for feeding a rod to the loading arm at the AP.
  • a loading arm 102 may be arranged pivotably on the cassette 106 and the loading arm may be capable of being turned from the GP to the AP past the drilling position without stopping at the drilling position. Accordingly, the loading arm may be moved from the GP past the drilling position to the AP. Between the drilling position the loading arm may be turned past an intermediate position illustrated in Figure 1c , before the loading may arrive to the AP illustrated in Figure 1d .
  • At least one rotating device 110, 112 may be operatively connected to a loading arm 102.
  • a lever arm 114 may be operatively connected to a mounting point 116 in the loading arm.
  • the loading arm may be rotated around its longitudinal axis illustrated by dashed lines in Figures 1a, 1b, 1c and 1d .
  • the rotating device may be capable of exerting a force that may be transferred to a movement of the loading arm by turning.
  • the loading arm 102 may be rotated by the lever arm.
  • the rotating device 112 may be connected to the loading arm via the lever arm 114. In this way the lever arm may be driven by the rotating device such that the loading arm may be turned. This allows positioning the rotating device and the loading arm at a distance of at least the length of the lever arm from each other.
  • the loading arm 102 may be rotated directly by the rotating device 110.
  • the loading arm may be rotated by the rotating device and the lever arm 114 may act as a support and/or guide means for the loading arm. Accordingly, rotation of the rotating device may be communicated to the loading arm directly from the rotating device.
  • the rotating device may have an axis that may be connected to the axis of the loading arm such that rotation of the axis of the rotating device causes rotation of the loading arm.
  • the axes may be connected by connecting the ends of the axes.
  • the loading arm 102 may be driven by more than one rotating device 110, 112.
  • One of the rotating devices may be directly connected to the loading arm and another rotating device may be connected to the end of the lever arm 114 remote from the mounting point 116.
  • the loading arm may be driven by two rotating devices, one of which is connected to the loading arm vie the lever arm and one of which is connected directly to the loading arm.
  • the lever arm 114 and the rotating device 110 directly connected to the loading arm 102 may be capable of rotating the loading arm simultaneously or separately.
  • both the lever arm and the rotating device communicate forces to the loading arm at the same time such that the loading arm is caused to rotate.
  • the lever arm and the rotating device exert forces to the loading arm at separate times such that the loading arm is caused to rotate. In this way the work of rotating loading arm can be shared to separate phases in the rotation of the loading device which allows controlling the rotation of the loading arm in each phase by only one of the lever arm and the rotating device.
  • a rotating device 110 operatively connected to the loading arm may be an electric device.
  • the electric device may transform electricity into movement of the loading arm 102.
  • the electric device may be directly connected to the loading arm for driving the loading arm such that the loading arm may be turned.
  • the electric device may be an electric motor.
  • a rotating device 112 operatively connected to the loading arm 102 may be a hydraulic device.
  • the hydraulic device may transform changes of hydraulic pressure into movement of the loading arm.
  • the loading arm may comprise a hydraulic cylinder that may be driven by the hydraulic device.
  • the hydraulic device may be connected to the loading arm by the lever arm for driving the loading arm such that the loading arm may be turned.
  • the hydraulic device may be a hydraulic pump.
  • a rotating device 110, 112 may be directly connected to the loading arm 102 for driving the loading arm and a lever arm may be operatively connected to a mounting point 116 in the loading arm for rotating the loading arm around its longitudinal axis.
  • the loading arm may be caused to rotate less than 90 degrees or substantially 90 degrees from the GP to a drilling position by the lever arm. After the drilling position, the loading arm may be caused to rotate to the AP by the rotating device directly connected to the loading arm. In this way the movement of the loading arm may be driven in phases, where one of the lever arm and the rotating device directly connected to the loading arm may drive the loading arm at a time.
  • the movement of the loading arm in phases may be supported by the cassette comprising mechanical stopping means.
  • the mechanical stopping means may set the lever arm to operate between the GP and the DP such that the lever arm cannot drive the loading arm beyond the DP. In this way the lever arm may be driven between the GP and the DP even without sensors for determining when the loading arm is the GP and DP.
  • the stopping means may be provided by a mechanical structure that may prevent movement of the lever arm away from the GP and to a position beyond the DP.
  • the stopping means may be a screw fixed to a position in the cassette for stopping the movement of the lever arm beyond the DP.
  • a hydraulic cylinder in the lever arm may have an eye that prevents the hydraulic cylinder to operate the lever arm beyond the DP.
  • a loading arm 102 may comprise gripping means 118 arranged to extend in a transverse direction to the longitudinal axis of the loading arm for receiving drill rods in the two loading positions, GP and AP.
  • the gripping means comprise a clamp.
  • the clamp may be designed and dimensioned to hold a single rod at a time.
  • FIG 2 illustrates a rock drilling machine 200 according to an embodiment.
