Abstract

An oil drilling rig is fitted with a swiveling magazine on which different types of bit, e.g. tricone bits or hammer bits (27), are stored. The bits are fitted with threaded adapters which allow them to be attached to the drill string and held by a clamp system (29, 30).

Description

The invention relates to a drilling rig for the drilling down holes of different or changing function with a drill carriage for scaffolding receiving scaffolding, arranged thereon rotary hammer or other drill with rotary gear and with detachably connected to the drill via an adapter drilling tool in the form of a roller chisel and with a clamping and breaking device for the be deposited in a rod magazine drill pipe, drill pipe and adapter are equipped with gripping surfaces for the grippers of the clamping and breaking device.

Holes are placed in the mountains or in the ground for different purposes. So it is known to introduce production wells for oil or natural gas with roller bits to perform core drilling with ring core or 3-wing crowns or drill bits to use where appropriate due to the hardness of the mountains. It is also known to introduce holes with, for example, drill bits, in order to then fill them with explosives and to win the comminuted rock with suitable equipment after the shooting down of the shots. Such blast holes are introduced when driving up tunnels and driving on tracks in underground mining but also where ores or minerals are mined in opencast mines. It is known to use rod magazines in which individual drill rods are kept, which are taken out of the rod magazine, pivoted into the drilling axis and then connected to the rest of the drill pipe so as to gradually drill into the mountains can. Of course, the rod magazines also serve to pull the drill string, the individual drill rods then record again for a split time. The connection and the release of the individual drill rods via known clamping and breaking devices. ( US-A-3,994,350 ). The roller chisel is to be connected via an adapter with the drill rods. It is necessary in order to carry out the dissolution process with the existing clamping and breaking device. Adapters and boring bars are provided with corresponding gripping surfaces. The introduction of explosives after drilling the holes is difficult, especially in waters, because it must be ensured that the individual explosive packages or packages also get into the borehole deepest. For this purpose, after the drilling down the hole with the roller bit or the drill bit with the help of a ring bit prerequisites are to be created, which allow flushing down the explosive packets to the borehole deepest. Therefore, both such drill bits as roller bits such as ring boring crowns must be held in such holes and connected if necessary with the drill string. This is very complicated by hand and difficult even with the help of cranes or the like, especially since the connection and release in the context of clamping and breaking device requires an accurate positioning of the individual parts.

The invention is therefore an object of the invention to provide a drilling holes of different function enabling drilling rig, which ensures short makeready times and avoids additional manpower.

The object is achieved according to the invention in that next to the roller bit a drill bit or 3-wing crown, and a ring bit or other drilling tool equipped with adapter are held in reserve in the rod magazine, the adapter a corresponding to the thread of the drill string and together are always formed with the associated drilling tool having the same length and that the rod magazine the framework in the The drilling axis is pivotally assigned and designed with footprints for the drilling tools.

Due to the special training once the drilling tools associated with the same adapter as well as the associated drill rods as a result of the special training of the rod magazine, it is possible to easily and safely bring the weight and handling problematic drilling tools as needed in the drilling axis and there to connect with the drill pipe or the drill rods. Similarly, it is possible to solve the front end of the drill string forming tools using the existing clamping and breaking device from the drill pipe, transfer the rod magazine and bring another drilling tool in the drilling axis, preferably to pivot, this now with the drill string to connect and use. It can be advantageously always worked with the same drill pipe and the associated machines, so not only a quick change of the respective drilling tool is possible, but also a fully effective work, because the right tool for the intended function tool is always available and just fast and can be safely brought into the drilling position or can be replaced. Thus, for the first time there is the possibility, with one and the same drilling device and here ultimately the same drill string and the known clamping and breaking devices both exploratory with a ring bit as well as a hole in more or less hard area with hard rock with the roller chisel or with make the drill bit in the hard rock or produce after production of the bore, for example, with the roller bit with the help of the ring bit a situation that makes it possible to inject or flush the blasting cartridges in the hole. At the same time the possibility is given to then bring the detonating cord in a position that makes detection easy and connecting to the other detonating cords, so that a variety of such blasting holes can then be dismissed in succession.

According to an expedient development of the invention, it is provided that the framework is a drill pipe made of a plurality of interconnected drill rods receiving and leading trained. Although this is associated with a correspondingly higher or longer scaffolding, but it makes it possible to realize a long Bohrweg, for example, of 20 meters and more. This makes it possible to drill a hole in the deepening of waters, for example, with a single drill string without extension need.

Earlier it has been explained that the individual drilling tools are kept in a rod magazine, which accordingly also receives individual replacement drill rods in addition to the drilling tools. This rod magazine is to be pivoted with the respective tool provided or the drill rod in the drilling axis, which is safe and easy according to the invention, because the rod magazine is arranged at the level of clamping and breaking device via a pivot arm articulated on the frame. This makes it possible, the rod magazine to the framework in the respective working position, d. H. into the drilling axis so that the respective drilling tool or the replacement drill rod can be removed and connected to the existing drill rods or vice versa.

In order to be able to pivot the respective drilling tool or the spare drill rod in the drilling axis, it is necessary to move the respective stand of this part in the drilling axis, which is easily possible according to the invention, because the rod magazine is rotatable about a central axis and a having the base surfaces having lower turntable serving as a stand surface receptacles for the drilling tools and / or replacement drill rods and an upper turntable. The respective receptacle with the drilling tool or the replacement drill rod arranged therein is thus first of all rotated into the intended working position in order then to pivot the entire rod magazine so that the intended component is then located in the drilling axis.

In addition to the stand areas or better said recordings on the lower turntable, the replacement drill rods should be conveniently performed at the top, which is made possible by the fact that the upper turntable of the boom magazine is equipped with resilient clamps for the drill rods. The respective replacement drill rod is pressed into the associated terminal, which then closes behind it, so that the drill rod is securely stored even at the upper end.

In order to ensure that both the ends of the drill string, ie the respective drill rod and the adapters, can be grasped and grasped with the grippers of the clamping and breaking device, the gripping surfaces on the adapter and on the drill rods take into account the spacing of the clamping and breaking device on the adapter or the respective boring bar. This requires special consideration of the gripping surfaces also on the boring bars, since the adapters are indeed much shorter than the boring bars. With appropriate dimensioning of the gripping surfaces on the boring bars but as it is possible to work with the known clamping and clamping and crushing devices.

A safe insertion of the drill string and the drilling tools in the respective clamping and breaking device is given because the clamping and breaking device are each assigned hydraulic drill pipe guides serving mainly as a drilling guide. In particular, the clamping and breaking device, d. H. Thus, the lower, the well facing device is associated with such a drill string guide to ensure safe drilling and piercing.

A simple and exactly the defaults appropriate discontinuation of drilling tools in the rod magazine is possible because the recordings for the drilling tools and also for the replacement drill rods in the rod magazine pot-shaped or peg-like and are placed on top of the lower turntable. Although it is then necessary, the drilling tool or The boring bar should be lifted slightly before it is swiveled into the drilling axis, but this is easily possible with the available grippers or gripping jaws. Due to the cup-like training, but is given a secure footing. Further back is explained how the drilling tools and the drill rods or spare drill rods can be stored even better in the rod magazine.

In the embodiment of the invention described above, the lower turntable is circular, with the replacement drill rods are arranged above all the drilling tools on the outer rim. But it is also possible, especially if more replacement drill rods are needed to form the lower turntable so that it has one or more, the drilling tools receiving, rotatable separately from the turntable additional plate, which are associated with the recordings for the drilling tools, the actual turntable more Has recordings for replacement drill rods. This makes it possible to arrange three drilling tools at one location, resulting in a much larger number of stands for the replacement drill rods. Of course, it is also possible to use several such additional plate, but sufficient after the present experience usually such an assignment of an additional plate.

In the final release of the connection between the drilling tool and drill rod or when loosening individual Bohrstangenverbindungen should be avoided that accidentally initiated or even carried out with the rotary gear breaking process, which is thereby avoided that the rotary mechanism of the drill to release the already broken drill rod / Drilling tool connection is set to a safety mode switching. The torque in the direction of loosening is then adjusted so that it is just sufficient to unscrew a already broken with the clamping and breaking device threaded connection. A break is safely excluded with a rotary gear.

A further embodiment of the invention provides that the framework is associated with a floating pontoon or a stabilizable ship and has deck guides which are capable of permitting a change of position in several directions. Just when, for example, when deepening a body of water, a plurality of holes are to be introduced nationwide, it is possible with this embodiment, from a point of view of the floating pontoon or ship simultaneously from a plurality of holes or better said to introduce one behind the other, then the floating pontoon to relocate and fix in a new position and bring in further drilling.

Earlier it has been said that the drilling tools are mounted in corresponding cup-shaped receptacles. Especially in rough drilling operation, it is advantageous if an additional security is provided at the upper end. For this purpose, the invention provides that the terminals for the adapter above the receptacles are assigned to a center plate arranged on the center axis. As a result, similar to the replacement drill rods, an upper and lower "fixation" of the drilling tools ensured, the adapter anyway have the shape of the drill rods and thus can be kept with the same terminals as the corresponding replacement drill rods.

The individual drilling tools can be mixed with each other, because they are the same in terms of their length and the adapter shape. Accordingly, it is provided that the adapters are always formed having the same length along with the associated drilling tool and accordingly always have the gripping surfaces in the same place. At the same time, replacement drill tools can be arranged so quickly, as they always fit into the provided receptacles and terminals.

Both with respect to the fixation of the drilling tools on the center plate as well as the replacement drill rods on the upper turntable is provided that the terminals are adjustable, preferably connected to the base plate of the upper turntable or the center plate accordingly. They can thus be adjusted in terms of their holding effect or spring action so that they still fulfill their function safely even after frequent use.

The compared to the drilling tools much longer Ersatzbohrstangen be held on the upper turntable via terminals, with an unintentional falling out of the rod magazine is additionally prevented by the fact that the upper turntable has a support edge plate with in the direction of lower turntable protruding support edge. Would this inaccurate classification of a replacement drill rod so they slip out of the terminal, it is safely collected by the support edge and thus damage to the drilling or even an impairment of the employee safely avoided.

However, in order to remove the replacement drill rods without problems from the rod magazine, the invention provides that the support edge plate is fixed and has a lateral recess in the support edge, which is closed by a segment slider in the storage condition of the rod magazine, via a flywheel together with the rod magazine is pivotable. Thus, if the rod magazine is pivoted into the drilling axis, the segment slide is thereby simultaneously opened so that now the proposed replacement drill rod can be removed without abutting against the support edge and thus affecting the upper turntable or the support edge plate.

In addition to the circular design of the linkage magazine according to the variant described above, there is also the possibility that the linkage magazine is rectangular and has a plurality of drilling tools and / or boring bars receiving pipe shafts, wherein the entire Linkage magazine or the individual drilling tools or boring bars are pivotable about per se known gripper into the drilling axis. In such an embodiment, although a corresponding gripper is necessary or better said two such grippers, but it may be advantageous depending on the training to use such a rectangular and thus compact rod magazine.

If the provision of replacement drill rods is not required, the rod magazine can also be made much smaller and compact and in that the rod magazine only drilling tools receiving is formed and this preferably consists of the lower turntable and the center plate and the center axis connecting them. This then only very short linkage magazine can be kept small because of the example, three or four drilling tools and the scope of the plate ago.

Another possibility is to use the present invention also where the provision of several different drilling tools is not absolutely necessary, the invention is also realized when the rod magazine only spare roller bits or spare drill sheaths or only spare ring drill bits and preferably formed with associated adapter receiving is. The then smaller compact rod magazines make it possible to significantly reduce the replacement times, since naturally also wear roller bits, drill bits or ring core bits and then have to be replaced. The previously required times are significantly shortened if, as described above, working with a suitably designed rod magazine. Of course, it is also possible to provide the Bohrwerkzeugplätze in a rod magazine, which always holds the necessary for the extension of the drill string boring, for example, when drilling deep holes. One of the places of the drill rods is then used for the spare roller bits, drill bits or ring core bits, which are associated with a correspondingly small additional plate, which is designed as such again rotatable to pivot the respective required drilling tool in the working position.

The invention is characterized in particular by the fact that a drilling frame is provided, which is extended by a rod magazine whose lower turntable recordings or stands are assigned for different or the same drilling tools. These drilling tools in the form of a drill bit, a roller chisel or a ring bit or other embodiment can then be taken out of this rod magazine, where you can fall back on conventional clamps or crushers. The linkage magazine is itself rotatable, so that the particular desired execution of the drilling tool in the working position, d. H. is pivoted into the drilling axis, in order to be connected to the linkage or later be released from it again. The respective set-up times or better said changeover times are considerably shortened, made much safer, because the access of the human hand is no longer necessary and also given the opportunity to have just such different tools at hand in the short term, if this is necessary proves. In addition, it is also possible to provide the individual drilling tools with the same replacement drilling tools in the rod magazine, so that they can run with necessary replacement work with the same advantage, as described above.

FIG. 1 shows a drilling rig 1, which is equipped with a carriage 2 and a drilling carriage 3, in which case the drill 4 is located at the upper end of the frame 5. This drilling frame 1 or framework 5 is installed on a floating pontoon 6, which rises over several legs 7, 8 on the bottom 11 of the water. These legs 7, 8 can after FIG. 2 be retracted so that then the entire floating pontoon 6 can be easily moved to a new working position. He can also have his own drives.

The drilling frame 1 or the framework 5 is to spend on deck 9 via deck guides 16 from one position to another, which is on hand FIG. 2 is clarified. Thus, a plurality of boreholes 12, 13 can be introduced into the lake bottom or base 11 of the water body with one and the same drilling frame 1. The water level 10 is indicated and recognizable are the fuses 14 connected to the respective borehole 12, 13 floating buoys 15, so that the necessary networking of each occupied with explosives holes is possible. About the control station 17 on the floating pontoon 6 all work can be monitored well.

In the embodiment shown here, the boreholes 12, 13 shown in the seabed 11 'are first introduced with a roller bit 27 shown later or a drill bit 26. After they have reached the lower position, the drilling tool 25 is pulled out of the borehole 12, 13 via the drill pipe 18. Then, the drill bit 26 or drill bit 27 is replaced by a ring bit 28, which now the same drill string 18 or a separate drill pipe in the borehole 12, 13 introduced. This is then given the opportunity to flush through the drill string 18 through the explosives and that with the respective detonator and thus the fuse or ignition 14. These are held at the bottom in the borehole deepest by their weight and by the possible deformation so that the ring bit 28 can be pulled out of the well with the associated drill pipe 18. It then stays with 14 and 15 marked position in the region of the borehole 12, ie the occupied borehole 12 is also easily and reliably identifiable from the water surface 24, so that after connecting the individual Schwimmbojen 15 and Zündleitungen 14 a plurality of shots can be dismissed simultaneously.

The above explanations clarify that a change of the drilling tools 25 is required, which was possible in the prior art only with the help of separate auxiliary equipment or by hand. FIG. 1 indicates that the drill string 18 or exploration drill string 19 or the entire scaffold 5 is associated with a boom magazine 20 for receiving required drilling tools 25. This linkage magazine 20 with the lower turntable 21 and the upper turntable 22 is rotatable about the center axis 23. Corresponding clarify the figures mentioned further.

FIG. 2 shows in addition to FIG. 1 in that an exploratory borehole 12 'can also be introduced first, because the devices required for this purpose can easily be stored. With 37 spare drill rods are marked, which can be kept in the above-mentioned rod magazine 20 with.

FIG. 3 shows the above-mentioned boom magazine 20 in working position, ie one of the support surfaces 36, 38 has been pivoted into the drilling axis 35, with the here also shown clamping device 29 and the clamping and breaking device 30 is not shown drilling tool 25 with the drill pipe 18 to connect. In detail are in FIG. 3 only replacement drill rods 37, 37 ', 37 "are positioned in the receiving pots 42 provided there, but it is also conceivable that here the already mentioned drilling tools 25 are arranged, which are arranged in FIG. 4 are shown. Denoted at 34 are the jaws of the clamping device 29 and clamping and breaking device 30, via which the respective boring bar 37 or else the drilling tool 25 can be gripped and fixed in order to release the connection or to produce it.

FIG. 4 shows three types of drilling tools 25, namely a ring bit 28, a drill bit 26 and a roller bit 27. All are equipped with an adapter 31 having above a thread 32 in the form of a nut piece that with the respective thread 33 of the drill rod to be explained 37 and the drill string 18 corresponds. This makes a secure and easy connection possible. Shown are also the gripping surfaces 39, which has each of these drilling tools 25, so as to allow a secure engagement of the clamping and breaking device 30.

In FIG. 3 the pivot arm 40 is shown, which allows pivoting of the entire boom magazine 20 from the working position to the rest position. The corresponding is in FIG. 6 shown. In FIG. 6 are also clearly in addition to the base surfaces 36 and receptacles 42 for replacement drill rods 37 and such support surfaces 38 are provided for drilling tools 25.

FIG. 5 shows a boring bar 37, which may be a replacement boring bar 37, or another ordinary boring bar inserted into the drill string. Even the term replacement drill rod makes it clear that an exchange with each other is possible here. These drill rods 37 are provided with gripping surfaces 39. By means of these gripping surfaces 39, 39 ', it is possible to engage respectively the clamping device 29 or the clamping and breaking device 30 in order to produce or release the boring bar / boring tool connection 50 or the boring bar / boring bar connection 51. The thread 33 having the upper end of such a drill rod 37 is referred to as the nut piece 56 and the lower end as the male piece 57, both having the same thread 33, with which the adapter 31 are equipped.

Also at FIG. 7 a rod magazine 20 is shown in the working position and in the rest position. Deviating from the illustration in FIG. 6 Here is one of the stands 38 equipped with an additional plate 47. This Additional plate 47 is rotatably mounted about the axis 48 on the upper side 46 of the lower turntable 21. The recordings 49 correspond to the recordings on the lower turntable, ie they are equipped with receiving pots 42. Arranged therein are either drill bits 26, roller bits 27 or ring core bits 28 or after in the FIGS. 13, 14 and 15 The embodiment of this embodiment is that only one stand for these drilling tools 25 is needed, so that the remaining stands all remain available for replacement drill rods 37. These recordings are denoted by 53, 54, wherein also this figure illustrates that the entire rod magazine 20 can be pivoted from the working position to the rest position or storage position and back again.

FIG. 8 shows such a rod magazine 20 in the neck, wherein here also different linkage in the form of the usual drill pipe 18 or the Erkundungsbohrgestänges 19 are shown, which can each be connected to each other or should. The connection is made via the already mentioned clamping device 29 and clamping and breaking device 30, wherein both a drill pipe guide 43 or 44 upstream or assigned, which is used here in particular with respect to the drill pipe guide 44 as a tapping guide.

FIG. 9 Fig. 3 shows the procedure for changing the drilling tool 25 here in the form of a roller bit 27. Starting with the extraction of the drill string 18 from the borehole, the boring bar / boring connection 51 and the boring bar / boring tool connection 50 are closed. After insertion and setting in the clamping and breaking device 29, 30, the drill rod / drilling tool connection 50 is broken in the second illustration. Then, the drill pipe 18 is raised with the dissolved drill rod / drilling tool connection 50 and that at the level of the lower turntable 21, which is now pivoted into the drilling axis 35, so that the roller bit 27 can be placed on it. Then with the Clamping device 29 of the roller bit 27 and its adapter 31 detected and turned off the drill pipe 18 via the rotary drive of the drill. The position is shown in the penultimate illustration on the right. The last diagram then illustrates the pivoting apart, ie the turntable 21 is pivoted out of the drilling axis, so that now another drilling tool 25 can be connected to the drill pipe 18. Mother and father pieces are here designated 56 and 57. In the FIG. 8 In addition, the nut piece of the drill pipe 18 is denoted by its own reference numeral, namely 58, in order to make clear that the drill rods naturally have a nut piece 58 on the end opposite the father piece 57.

The FIGS. 10 and 11 show the upper turntable 22 once in the view in the turntable into it from below and then from above. It is made clear that the actual base plate 63 of the upper turntable 22 with terminals 60, 61 is equipped to thereby determine the upper end of the replacement drill rods 37 can. This base plate 63 pivots together with the entire rod magazine 20, while the also reproduced support edge plate 64 with its downwardly facing support edge 65 remains fixed. Falling out of the replacement drill rods 37 is prevented by this support edge 65, but can be opened when a targeted removal of replacement drill rods 37 is necessary. For this purpose, a lateral recess 66 is provided in the support edge 65, which is closed in the storage state of the linkage magazine 20 via a segment slide 67. This segment slider 67 is connected via a pivot lever 68 indirectly via a pivot axis recording 69 with the center axis 23, so that when pivoting or rotating the rod magazine 20, the segment slider 67 moves simultaneously, so that the lateral recess 66 is opened.

FIG. 12 shows a center plate 62, which serves as an upper fixation for the respective drilling tools 25, that is also equipped with corresponding terminals 60 ', 61'. This center plate 62 also makes it possible to work with a very short training a rod magazine 20, namely when on Spare drill rods 37 can be dispensed with. These are still indicated here and also clarifies that the terminals provided here 61 'for intermediate fixation or for optimal attachment and fixing the replacement drill rods 37 in the rod magazine 20 can participate and used.

The pot-or pin-like receptacles 42, 53, 54 for the pipe tools 25 and the replacement drill rods 37 are associated with the lower turntable 21, wherein the determination on the upper side 46 is illustrated here.
