Definitions

  • the invention relates to a drilling arm, as it is used on wagons or the like.
  • drilling arms are used not only to make blast holes but also to drill holes for anchors. If anchors are set, the drilling arm can also serve as a support for an anchor setting device.
  • the mobility of the drill arms is of great importance, since the aim is to be able to drill as many holes as possible from one position, whereby on the one hand it must be possible to position the drill precisely on the rock and on the other hand the alignment of the drill carriage carrying the drill must be guaranteed according to the desired angle.
  • a drilling arm which has a bracket that is provided for connecting the same to the carriage, this bracket has articulations for a drilling boom, which has a lifting and lowering cylinder and a swivel cylinder, which are also on the console are articulated, is movable.
  • This drill boom has at its distal end a rotary motor which carries a fork head which in turn carries a pivot shaft via an arm which in turn has the mount holder with mount.
  • Such a drilling arm is characterized by a particularly simple construction, which at the same time offers the possibility of various positions.
  • a disadvantage of a drilling arm of this type is that there is a particular need for space when positioning the drilling device.
  • the object of the present invention is to create a drilling arm which allows the mount to be arranged on both sides of the drill arm, with a complete equivalence in the positioning of the mount, in particular in the two end positions, being provided in both mount positions.
  • the drilling arm with a bracket, an articulated, optionally telescopic boom, which can be moved via a lifting and lowering cylinder and a swing cylinder, the boom at its distal end, which can be rotated about the longitudinal axis of the boom, e.g.
  • a pivot axis on which a carrier which can be pivoted by means of a cylinder or the like is mounted, in which a carrier shaft which is arranged essentially normal to the pivot axis and which carries the drill carriage holder with drill carriage, drilling device and, if appropriate, anchor setting device, essentially exists in that an arm is mounted on the carrier shaft, which has a further shaft at its distal end, which is connected to the mount holder, the carrier shaft and the further shaft being arranged essentially parallel to one another.
  • a particularly good mobility is given when the further shaft and the carrier shaft are each arranged in a preferably hydraulic rotating cylinder.
  • the drill carriage can be arranged particularly far on both sides of the boom.
  • the drill mount can assume any angular position.
  • FIG. 1 shows a drilling arm which is mounted on a drilling carriage, in a side view and
  • FIG. 2 shows the drilling arm according to FIG. 1 in a top view.
  • the carriage 1 partially shown in FIG. 1 carries a bracket 2 which has tabs 3 to which the boom 4, the lifting and lowering cylinder 5 and the swivel cylinder 6 are articulated.
  • a rotary cylinder 7 is provided, which is fastened on a telescopic extension (not shown) in the boom.
  • the rotary cylinder in turn carries a further boom part 8, which carries a fork head 9 at its distal end.
  • a shaft 10 is mounted, on which a carrier is pivotally mounted via a cylinder 12.
  • the carrier 11 in turn has a rotary cylinder 13 in which a carrier shaft 14 is provided.
  • an arm 15 is rotatably mounted by 180 °, which has at its distal end a rotary cylinder 16 with a further shaft 17, which in turn carries the mount holder 18, which can be rotated by 180 ° , intended.
  • the carriage 19 is fastened to the carriage holder, along which the drilling unit 20 can be displaced, optionally with an anchor-setting device.
  • the drilling steel 21 is driven into the rock through the guide 22, the carriage being supported on the rock by the mandrel 23.
  • supports 24, 25 are provided on both sides of the console, which support the console on the floor 26.
  • the rotary cylinder 13 is actuated, causing the arm 15 to move from its one end position to the left of the boom into the other end position to the right of the boom (shown in dashed lines in FIG. 2) comes to lie. Simultaneously with this rotational movement of the arm 15, an opposite rotational movement is carried out in the rotating cylinder 16, so that the mount can continue to be arranged parallel to the boom.

Claims (4)

1. Bras de forage avec une console (2), une volée (4) articulée sur celle-ci, éventuellement télescopique, qui est mobile sous l'action d'un vérin de montée et descente (5) et un vérin de rotation (6), où la volée (4) porte à son extrémité distale, éventuellement tournante autour de l'axe longitudinal de la volée (4) un pivot engagé par exemple dans une chape (9) sur lequel est mobile, au moyen d'un vérin ou analogue, un support pivotant (11) sur lequel est monté un arbre support (14), disposé sensiblement perpendiculaire au pivot, qui porte le support d'affût (18) avec l'affût (19), un dispositif de forage et éventuellement des moyens d'ancrage, caractérisé en ce que, sur l'arbre support (14) est monté un bras (15) qui présente à son extrémité distale un autre arbre (17) qui est lié au support d'affût (18), en sorte que l'arbre support (14) et l'autre arbre (17) sont disposés sensiblement parallèles entre eux.
2. Bras de forage selon la revendication 1, caractérisé en ce que l'autre arbre (17) et l'arbre support (14) sont disposés chacun dans un vérin vireur (13,16) de préférence hydraulique.
3. Bras de forage selon la revendication 1 ou 2, caractérisé en ce que, à partir d'une position extrême du bras (15) dans laquelle celui-ci est disposé sensiblement perpendiculaire à l'axe de volée, il peut pivoter dans l'autre position extrême, sur environ 180°.
4. Bras de forage selon la revendication 1, 2 ou 3, caractérisé en ce que le support d'affût (18), à partir d'une de ses positions extrêmes où il est disposé sensiblement perpendiculaire au bras (15) peut pivoter dans l'autre position extrême, sur environ 180°.
