Definitions

the invention relates to a device for drilling, in particular for rotary drilling of rock or the like. With a device for loosening the drill pipe.
a multipart drill pipe is used, which is gradually extended respectively with another drill rod.
the process is such that the boring bar, including the drill bit, is advanced until the connection point between the stub and the boring bar comes close to the borehole.
the drill rod is then held in a rotationally locking manner, for example with an open-ended wrench or the like, and the stub is rotated out of the rod in the opposite direction to drilling or rotary impact drilling, be it via the rotating assembly or its own motor.
Hiebei it can be advantageous before loosening the connection that the rod is pulled a short distance from the borehole, whereupon so-called blows on the stub take place, whereby the threaded connection is easier to release.
the drilling unit is arranged on a carriage and is moved backwards after loosening the threaded connection, whereupon a new boring bar is inserted, which is connected via the normal rotary movement to the drill pipe, which is still held, and the stub.
the fork wrench is then disengaged and the drill pipe is ready for further use. If the drill hole has now been made to the desired depth, the individual drill rods must be pulled out of the drill hole again. It is necessary for the connections of the boring bars to be loosened step by step.
boring bars are usually used, which on one End have an external thread and at the other end an internal thread, both the external and the internal thread having the same diameter.
the sleeves which have the internal thread, are subject to a particularly high load, so that the sleeves break prematurely. It has therefore proven to be favorable that the drill rods have external threads at their two ends, each of which can be connected via a sleeve which has a corresponding internal thread, which can either be continuous or divided into two and in the same direction.
the present invention has set itself the goal of creating a device which avoids the disadvantages mentioned above, and allows to apply the moment for loosening the jammed thread and then screwing it onto the linkage, with no positive locking between the gripping elements and sleeve being required.
Open-end wrench or the like which preferably holds the drill pipe pointing into the borehole, consists essentially in that at least one gripping element is provided in a rotor which is rotatable about the axis of the drill pipe in a housing and which can be actuated by the further drive the gripping element (s) has a working surface (s) which, in contact with the drill pipe, enclose an angle equal to or smaller than the self-locking angle (s).
the production of boreholes and in particular the pulling of the drill pipe can be carried out particularly quickly since the gripping elements only act on the drill sleeve or the like via frictional engagement, as a result of which a high torque can be exerted, even if the sleeve or the like is already subject to severe wear during drilling operation, with unscrewing of the boring bar being possible simultaneously in the same working position.
a particularly simple constructive solution which at the same time allows the work surface to be easily adapted to the circumstances, consists in that at least three cam-shaped gripping elements are mounted on the rotor, wherein the respective work surfaces are partially cylindrical, and the axis of the cylinder is outside the pivot axis of the gripping elements.
the gripping elements can be replaced particularly quickly, which is particularly important when a gripping element breaks or when the device is changed over for a drill pipe with a different diameter Meaning is.
the rotor has an external toothing into which a drive pinion meshes.
the rotor has a hollow axis through which the drill pipe can be guided, this results in a particularly simple and trouble-free construction.
a ring which has drivers for the gripping elements, is mounted in the rotor and can be held by a housing surrounding the rotor, the gripping elements can be engaged in a particularly simple manner by rotating the rotor.
the gripping elements can easily be pivoted out by rotating in the opposite direction.
Accurate centric guidance of the drill string which is advantageous for fast clamping of the drill string in the device, can be achieved by providing at least one, preferably two guides centrally to the rotor, in particular with a truncated cone and a cylindrical surface for the drill string (are).
the relative movement between the drill pipe and the device according to the invention when the invention is solved is taken into account in a particularly advantageous manner in that the rotor, preferably together with the further drive on the mount, can be moved in the axial direction of the drill pipe, and possibly via resilient elements, cylinders or the like. is movable into a rest position.
FIG. 1 shows a mobile drilling device with drilling arm and drill carriage
FIG. 2 shows a drilling arm
FIGS. 3 and 4 shows a clamping device with cam-like gripping elements
FIG. 5 shows the schematic representation of a clamping device with rollers.
a vehicle 2 is provided on the vehicle 1 shown in FIG. 1, which is calculated for the operator. Furthermore, a hydraulic unit 3, which serves to drive the drilling arm 4 and the rotary impact unit 5 and the clamping and turning device 6 and the key 7, is provided. The percussion device lowers along the carriage 8 during drilling until the stub 9 comes close to the clamping and rotating device. The threaded connection between the drill pipe and the stub is then released and the rotary impact device is brought into the starting position shown in the drawing. W pus a new drill rod is placed in the rig, the drill string downhole held by the key 7 connected to the new drill string and simultaneously screwed into the Einsteckstummel. This process is repeated until the desired drilling depth is reached. Then the drill pipe is lifted step by step and one drill rod is separated from the remaining drill pipe, the drill pipe located in the borehole being held in place by the key 7, and the connection is released via the clamping and rotating device.
the drilling arm shown in FIG. 2 is connected to the tracked vehicle via a bracket 10.
the console 10 has flanges 11 which carry a telescopic boom 12 which can be adjusted in height and in the sides via the cylinders 13, 14.
the boom carries a swivel head 15, which in turn carries the mount holder 16, pivotably via a cylinder 16a.
the carriage 8 has at one end longitudinally displaceable the impact rotary drilling device 5 and at the other end the clamping and rotating device 6. In the position shown in FIG. 2, an essentially horizontally oriented borehole is drilled.
FIG. 3 shows a clamping and rotating device, partly in section and in top view, whereas in FIG. 4 the section along line 4/4 according to FIG. 3 is shown.
the housing 17 is guided on the carriage 8 via a slide shoe 18. 4, a rotary motor 19 is fastened in the housing.
This rotary motor 19 drives the rotor 21 via a pinion 20.
This rotor has an external toothing 22.
the rotor has a hollow axis 23 which is mounted in the housing 17.
the self-locking angle should not be greater than three angular degrees if the gripping elements J and the drill pipe are made of steel. That 27 of the grasping element is defined by 2, where the compound of the axis of the drill string 30 and the axis of rotation: the self-locking angle in this case, as shown in Figure 3a can be seen by the sum of W and inkelcC i. E.
the second leg of these two angles is defined by the line of contact 37 between the gripping element and the sleeve.
this angle is equal to or smaller than the angle of the self-locking, the gripping elements come to the immovable engagement on the smooth surface of the drill string, whereby effortless loosening is given, while at the same time a high moment arises over the relatively large diameter of the rotor 21 the sleeve can be applied so that trouble-free loosening is easily possible.
FIG. 5 which can be installed in the device according to FIGS. 3 and 4, it has inner wedge surfaces 38 which cooperate with rollers 39, these rollers being able to be brought back into contact with the drill sleeve.
the angle ⁇ of the self-locking is defined here by the tangents on the roller 39, which is given by the points of contact on the sleeve 31 or on the wedge-shaped surface 38.
the clamping and turning device is moved from its position along the mount when the sleeve is unscrewed. When the unscrewing process has ended, the device is returned to its starting position by means of the spring 40.
