Definitions
- the invention relates to a device for producing boreholes a clamp mount, on this movable drill drives over which the drill pipe, consisting of inner tubes and outer tubes driven into or pulled out of the borehole is, and one arranged parallel to the clamping mount and about the axis of rotation rotatable and pivotable about a longitudinal axis of the clamping carriage drum magazine for the inner and outer tubes, as well as the clamp mount assigned Clamping pliers for screwing and loosening the drill pipe.
- Such devices have a caterpillar on which one Clamp mount on articulated arms is movably mounted in different directions.
- On this clamp mount is a drivable drive with which the Inner tube and the other the outer tube can be applied to both to drive into the ground simultaneously or individually or together from the ground pull out again.
- Those used to continue operating the device Inner and outer pipes are already joined together to form the drill string Connected tubes, which are assigned to the clamp mount clamps hold the last pipe of the drill string or the pipe to be connected accordingly rotate.
- Drum magazines to hold the individual pipes of the drill pipe are both for drilling with the single pipe linkage and the double pipe linkage known.
- EP-B1-0 527 460 describes a method and a drilling device in which the Drum magazine consists of two separate magazines arranged one above the other and where the individual tubes from the magazines one after the other be removed.
- the main disadvantage here is that here the individual magazines are arranged one above the other, so that an unfavorable for the overall machine Weight load results. Not least for this reason can only be proportionate short pipes are used, which results in frequent rod changes draws.
- the two drum magazines are moved from a kind of outside position into the Working position swiveled to then be rotated so that the intended Inner or outer tube can be removed. After removing the The magazine must then be swiveled back into its storage position in the respective tube become. The effort involved is considerable.
- US-A-5 215 153 a device with a raising and lowering arrangement.
- the invention is therefore based on the object of a device for drilling of drilling holes, with the inner and outer pipes separated in one Drum magazine can be stored, but can easily be used together without losing stability the carriage or the entire drill during the individual manipulations endangered is.
- a clamp at the lower end of the clamping carriage movable and corresponding in its longitudinal axis is arranged so that it can be actuated with the pivotable and rotatable drum magazine, that the inner and outer tubes can be removed radially from the drum magazine and over Clamps are assigned and that the drum magazine is assigned a clamping roller arrangement for lifting and lowering the inner tubes.
- each one can be advantageous Inner tube and each individual outer tube stored separately in the drum magazine to be merged if necessary and then by swiveling and rotating of the drum magazine to be arranged in the drilling axis in order to use the usual devices such as drive and clamps connect to the existing one Manufacture double pipe string.
- the one that can be moved in the longitudinal axis of the clamping carriage Clamping pliers take out the corresponding pipes or the double pipe the drum magazine so that it "processes" in the appropriate position can be.
- Every single pipe is there and therefore also the one that is inserted into the other Inner and outer tubes on the outer circumference of the drum magazine easily for the clamp pliers and the other support facilities available to them as mentioned from the Take out the drum magazine or when pulling the drill pipe again to store there accordingly.
- the No separate grippers or cranes required for inner and outer tubes and the boring heads do not have to operate, but from the drum magazine the inner tubes are raised and lowered into the outer tubes. The combination of inner and outer pipe is then brought into the drilling position and connected to the existing drill pipe as described.
- the Clamping pliers on the clamping carriage over a travel distance of 1 to 2 m, preferably 1 m is arranged.
- This training enables the clamping pliers to be used in a position as favorable as possible to the double pipe or possibly that remove individual tube from the drum magazine and fix it in the drilling position, to then connect it to the existing drill string.
- Another expedient version is the one in which the drill pipe in Drum magazine fixing clamps are arranged and designed so that the Seen inside and the outer tubes radially, separately or in groups separately over the drum circumference are distributed.
- the drill string when pulling the drill string first the inner tubes are pulled, they can be moved in the smallest way the drum magazine can be classified. Then the outer pipes are then successively drawn, which are also classified into the drum magazine in the smallest possible way can be done so that this work can be carried out quickly.
- This arrangement of the individual tubes has an interlocking arrangement of the inner and outer tubes or the drill pipe in the drum magazine has the advantage that without mutual hindrance of tubes, these are taken out of the drum magazine and placed one inside the other can be.
- the clamping pliers which can be moved in the longitudinal axis of the clamping carriage, are after one Embodiment of the invention actuated by clamping cylinders, which are arranged parallel to each other are and one of which has a deflection device.
- This particular one Training gives the opportunity to use the drum magazine without a disability to be pivoted into the drilling axis by the second clamping cylinder of the clamping pliers, to remove the double tube or the single tube from the magazine.
- the deflection device is nevertheless given the certainty that the cylinder has the necessary Applies force to the double tube or the tube from the drum magazine to hold on and fix in the drilling axis so that a connection with the existing Drill string is easily possible.
- the deflection device has one, one of the clamping jaws Showing elbow, which is articulated with the piston of the clamping cylinder connected is.
- This allows working with a conventional clamping cylinder be secured over the contra-angle handpiece against adverse forces in the respective position.
- the contra-angle is once with the clamping cylinder and secondly connected to the jaw, the articulated or movable Connection prevents or compensates for the influence of oblique forces.
- the angle piece with a bolt is connected to the piston and has an elongated hole guide in the elbow.
- Extending the piston does not interfere. Rather, it is an even one and secure pressing of the clamping jaw on the respective tube, whether it is is an inner or outer tube.
- the inner and outer tubes have a clearly different diameter exhibit.
- the travel of the elbow is correspondingly different or rather the clamping cylinder. Cross-country skiing is prevented here as well as the articulated connection with the piston of the clamping cylinder or any other negative impairment.
- the desired synchronization is achieved in particular by the fact that the parallel Clamping cylinders are selected with respect to the piston and ring surfaces, preferably 100: 60 that the desired synchronization is certain. It can also be used in parallel Arrangement or if there is a displacement of the two cylinders for reasons of space proves necessary, nevertheless ensure that about the two Clamping cylinder ultimately the same pressure is exerted.
- the invention provides that at the level of the upper edge of the drum magazine of the clamping mount, a holding clamp for the inner tube is provided is.
- This holding clamp acts when moving together with the existing drill string also positive in that it keeps the inner tube in a separate position for so long until the drive has caught the inner tube to connect with the existing one To reach the inner pipe or pipe string. After connecting the inner tube then the outer tube, which is held over the already mentioned clamp, is connected become.
- the holding clamp has gripping pliers, whose clamping wings can be pivoted against the force of retaining springs via a cylinder are trained. With advancing the cylinder or extending it the clamping wings in the rear area pressed apart against the force of the retaining springs in the front area against the wall of the respective tube to be pressed. It is also conceivable to do without the retaining springs, only then is the swinging out or springing back of the clamping wings a little more difficult to reach.
- the end rollers has that favorably curved to the opening and closing of the clamping wing Inner surfaces of the clamping wings are arranged and formed so that they can be pressed on. How nice mentioned is the possibility given to separate the clamping wings in the rear area and against each other in the front area assigned to the tube to be clamped to move. In the shortest possible way, this is possible with the necessary strength, if, as described, the rollers along the correspondingly curved inner surfaces be performed.
- Loads on the drum magazine when swiveling and also when removing the respective drill string from the clamps is made according to the invention this prevents the axis of rotation of the drum magazine.
- the drum magazine can then "load" the outer tubes with the inner tubes or can also be actuated when swiveling into the drilling axis in such a way that the respective drill rods reach and maintain the correct position without The axis of rotation may be overloaded.
- the inner tubes are threaded into the outer tubes moved out of the drum magazine with the aid of a pinch roller arrangement.
- a pinch roller arrangement To prevent swiveling when starting up and the best possible
- Inner tubes is arranged at the upper end of the clamp mount.
- This funnel-shaped introduction can be a Act end station management, or also an intermediate management, whereby also the It is possible to combine the two in order to find the optimal position the inner tube on the clamp mount.
- These funnel-shaped entries or, above all, the end guide also prevent that on the pinch roller arrangement unfavorable forces act because the respective inner tube to be pulled out an unintended direction threatens to tip over.
- Make the respective introductions for the other facilities within the scope of the clamp mount it does not represent a disability.
- the inner tube with the pinch roller arrangement is retracted and extended uniform and possible even in unfavorable conditions if the Pinch roller assembly has two driven rollers, the opposite and at the same time arranged to be pressed against the inner tube and designed to be rotatable.
- the rollers preferably have a common drive, which is can be a compressed air or electric drive.
- the casters are expediently arranged so that they encompass the respective tube slightly and can, for example, avoid so far with trained sleeves that an always secure fixation of the inner tube is guaranteed.
- the secure fixation for example in the area of sleeves, is particularly important then guaranteed if the rollers as to fit the pipe profile Sigma rolls are trained.
- These sigma rollers have sufficient drive surfaces so as to ensure the application of the necessary forces to the inside and at the same time form a certain guidance through the special curved design of their treads.
- the necessary pressure forces are in a preferred embodiment of the Pinch roller arrangement achieved in that the rollers have axle holders that can be swiveled with a bracket and can be changed in length using a bracket trained spacers are connected.
- the axle holder can be rigid on the Stored bracket to be pivoted back and forth according to requirements or swing back and forth, the spacer executing this movement and at the same time ensures that the necessary pressure forces are exerted on the axle holder the rollers or on the rollers can be applied to the pipe wall.
- the spacers could be springs, yes compressed air cylinders or similar components are ideally suited to simultaneously re-springing and to ensure sufficient pressure.
- Threading the Inner tubes in the outer tubes the inner tubes should protrude slightly above the outer tubes, in order to keep them graspable via the holding clamp or the clamping pliers.
- the pinch roller assembly thus moves the inner tube so far into the outer tube until the inner tube is seated on the respective guide pin. Then dissolves the pinch roller assembly and returns to its original position, so that subsequently the nested tubes are also removed from the drum magazine can.
- the dimensioning of the guide mandrels then ensures that the Grasp the clamp that is used to fix the inner tube in the drilling axis can.
- the present invention also has a proposed solution here, to optimize the overall operation of the device resulting from this distinguishes that the inner pipes with inner channel welded end pieces with inner or have external threads, which are sleeve-shaped, each with corresponding Chamfers are provided. Due to the welded end pieces Possibility given, the inner channel, which was previously quite limited in diameter to enlarge, so that accordingly more drilling fluid through the inner channel can be transported. In particular, however, the inner channel becomes continuous uniformly formed so that the flow of the drilling medium in the area of Transitions is not affected.
- the invention provides that the exterior and the internal thread of the end pieces also ends before the bevels are. So that there are no surfaces of the two to be joined together Pipes flat on each other, rather it is ensured that there is always a small one The distance remains because these parts do not fit on each other due to the thread can come. This makes it easier to detach the pipes from one another.
- the transport of the respective drilling medium or drilling fluid is thereby optimizes that the end pieces have a diameter of the inner channel of at least 30 cm with approximately the same wall thickness. It is advantageous that despite the very large inner channel, the necessary wall thickness is guaranteed, which guarantees long service life, which in turn also optimizes Handling guaranteed.
- the occurring increase in the outer diameter of the inner tubes is harmless because there is an adequate ring channel opposite the inner wall the outer tubes remain and because of the pinch roller arrangement used secure gripping and holding of the inner tubes even in the area of these sleeves ensures.
- the invention is particularly characterized in that a device is created, with which both single and double pipe work can be.
- the inner and outer tubes can be easily placed in the drum magazine be stored safely and so separately from each other that they either handled separately or collapsed in the drum magazine if necessary can be plugged in and then used as a double tube.
- the separate storage also has the advantage that when pulling the used The individual pipes are placed one after the other in the drum magazine can be because the inner tube is always pulled first and only then Outer tube. Another advantage is that due to the accommodation in the drum magazine separate use is possible, but above all with the help of simple ones Pinch roller arrangement also in a combined arrangement.

- clamping pliers 10, 11, 12 At the lower end 15 of the clamping mount 2 there are a number of clamping pliers 10, 11, 12 attached, which serve either the outer tubes 8 with the in the borehole located outer tube or the inner tubes 9 with the inner tube located in the borehole to connect each or when pulling the drill pipe 7, the individual parts to separate from each other.
- a funnel-shaped insertion 13 reproduced, in which the inner tubes 9 are inserted when you are out of your Bracket in the drum magazine 6 are pulled out, then in the neighboring To be inserted outer tube 8.
- a second funnel-shaped insertion 19 can also be provided, which is actually the end guide, while the funnel-shaped Introduction 13 represents an implementation for the inner tube 9.
- the funnel-shaped entries 13, 19 serve, as mentioned, to guide the Inner tube 9 when it is moved out of the drum magazine 6 to then to be inserted into an outer tube 8.
- a pinch roller arrangement is used for this 20, which is arranged on the upper edge 46 of the drum magazine 6.
- the drum magazine 6 pivoted into the drilling axis 26, in order to then be gripped by the clamping pliers 10 and to be fixed.
- the clamping axis 10 is at the lower end 15 of the clamping mount 2 arranged and can over the entire travel path 16 in the longitudinal axis 18 of the tubes 8, 9 or then in the longitudinal axis 17 of the clamping carriage 2.
- This can the outer tube 8 or the inner tube 9 are each fixed so that it is subsequently connected to the outer tube in the borehole or to the inner tube in the borehole can be.
- the other clamping pliers 11, 12, which are used for this purpose, serve this purpose Secure the drill strings.
- Fig. 2 shows indicated the pivoting process with which the reciprocated Outer tubes 8 and inner tubes 9 are pivoted into the drilling axis 26, for which purpose the clamp mount 2 is connected to a swivel arm 21, which is about the swivel axis 24 can be pivoted that the respective combination of inner tube 9 and outer tube 8 is located in the drilling axis 26.
- the clamp mount 2 is connected to a swivel arm 21, which is about the swivel axis 24 can be pivoted that the respective combination of inner tube 9 and outer tube 8 is located in the drilling axis 26.
- the drum circumference 25 arranged combination tube can be used after the drum magazine 6 over the swivel arm 21 has been brought into the extended position in FIG. 2.
- the pipe combination 8, 9, is gripped by the clamping pliers 10, which also in FIG. 2 is reproduced.
- the position of the pinch roller arrangement 20 and 20 is also indicated in FIG also the axis of rotation 23, which is so arranged and designed that overloads are not are to be feared, why it is movably mounted.
- Fig. 3 shows a drum magazine from the pre-gel perspective, clearly is that the inner tubes 9, 9 ', 9' 'and the outer tubes 8, 8', 8 '' each in groups are arranged distributed over the drum circumference 25. They are each about Clamps 27, 28, which the respective outer tubes 8 or inner tubes 9 over fix their curved free ends 29, 30 securely. It can be seen from this representation that the respective outer tubes 8 and inner tubes 9 after pivoting of the drum magazine 9 in front of the clamping mount 2 via the clamp 10 from it Position can be taken to in the drilling axis 26 with the existing Drill string to be connected.
- This clamp 10 is shown enlarged in Fig. 4, wherein it in this respect a special training and one of the representation in FIG. 2 deviating figure in so far acts as the clamping cylinders 31, 32 in parallel next to each other lie. Nevertheless, the respective outer tube 8 or Inner tube 9 are securely held and fixed because the clamping cylinder 32 has a Deflection device 33 has. This gives you the option of using these cylinders to fix the respective tubes 8, 9 securely by the clamping jaws 34, 35 be driven against each other.
- the clamping cylinder 32 therefore has an elbow 36, which is connected to the piston 37 and the other to the opposite side carries the jaw 34.
