Definitions
- the invention relates to a drill with impact device according to the preamble of claim 1.
- the object of the invention is in a drilling rig specified genus a simplified training of Percussion mechanism with reduction of the required parts achieve and at the same time the external space requirement for to reduce the striking mechanism. More related to everything Problems with which the invention is concerned result from the respective explanation of the identified solution.
- a direct drive is provided for the striking mechanism.
- the training is made so that a freewheel in torque transmission from direct drive to crank directly on the output shaft of a drive motor is arranged. This results in a compact design.
- the rope can be on the crown of the mast or one Mast extension via a centrally arranged crown roll to run.
- the crown of a mast or a mast extension cross-shaped.
- a such a crown usually has two roles for one Drill or main rope on. In such and similar cases is conveniently a single crown roll for that Lay rope parallel to a roll for a second rope arranged.
- the drill 1 shown in Fig. 1 has i.a. one on a crawler chassis 2 arranged chassis 3, a Mast 4 with mast extension 5 and an impact device on a free fall winch located on the chassis 3 6 for a rope 7 and a striking mechanism 8 contains.
- the number 9 is designed in the manner of a crosshead Crown of the mast or mast extension designated.
- winch is just like others to one Parts and units belonging to such drilling equipment are not shown. It is only a at 12 Mast 4 movable power turret and at the number 13 a drill string guide or the like. indicated.
- FIGS. 2 and 4 is the striking mechanism 8 as an installation part of the mast extension 5 integrated into this, i.e. so assembled with her that that indicated in Fig. 4 with a dashed line B. Movement range of a hammer mechanism roller 14 partially lies within the mast extension 5. Which the outline contour the mast extension limiting components of the same are shown in Figures 2 and 4.
- the percussion roller 14 is one on the pin 15 Crank 16 mounted, which itself via a bearing 18 from a in the mast extension 5 seated housing 17 rotatable is recorded.
- a direct drive provided in the form of a motor 19, the one Electric motor or a pressure medium motor can be.
- a freewheel 21 is arranged, via which the torque transmission from the output shaft 20 to the crank 16.
- the rope 7 coming from the free fall winch 6 runs via the hammer mechanism roller 14 to a single, in the mast extension 5 mounted pulley 22 and from this directly to a stored in the crown 9 Crown roller 23, from which the rope descends a striking tool or the like, not shown. leads.
- the crown roll 23 for the rope 7 is parallel to the roller 10b arranged for another rope 11, such as 2 in particular.
- the striking mechanism 8 also be integrated directly into a mast 4.
- the above explanation then applies analogously and accordingly, in Figures 2 and 4 instead of the mast extension 5 the mast 4 is to be thought.
- the spot, where the striking mechanism 8 is integrated in the mast 4, especially with regard to the height, may vary according to the circumstances and other training of the Align mast or drill.
