Abstract

The method involves transporting drill pipe sections (20) for extending a drill pipe by a transport unit individually one after another from a drill pipe supply area through a shaft access opening (16) into a shaft structure. The drill pipe supply area is arranged outside of the shaft structure.

An independent claim is also included for an arrangement for manufacturing or expanding bore or for replacing a pipeline.

Description

The invention relates to a method and an arrangement for producing and / or widening a borehole and for replacing a pipeline laid in the ground by means of a shaft boring machine. For this purpose, a shaft boring machine is introduced into a shaft structure. The jig boring machine drives a drill pipe assembly that can be assembled from a plurality of pipe sections and thereby moves a tool present at the front end of the drill pipe. Known shaft boring machines are introduced through a manhole access opening into the manhole structure and arranged there in the depth required for a starting point of a horizontal boring. To create a straight horizontal bore, the drill pipe and the tool located at the forward end of the drill string are continuously rotated as the drill string advances. The tool preferably has an asymmetrical shape so that it drifts sideways, upwards and / or downwards without rotation depending on the orientation in one direction. As a result, the course of the horizontal bore can be selectively influenced. With suitable measuring means the position of the tool can be determined exactly, so that the course of the horizontal bore can be controlled relatively accurately. The shaft construction serves as a starting shaft when creating a horizontal bore, wherein the target point may be another shaft or a building. After the front end of the drill pipe has reached a target point in the target shaft or in the target building, the tunneling tool can be exchanged for a flaring tool. The expansion tool can also be used to connect a pipeline to be recovered. Through a Retraction of the drill string with the help of the shaft drilling machine, the hole can be widened and simultaneously retracted a pipe.

From the document DE 101 59 712 B4 For example, a method and apparatus for making and expanding horizontal wells are known in which a wellbore drill is inserted into a cylindrical well. From the document DE 102 57 392 A For example, there are known a method and an apparatus for creating a channel through the soil, in which a shaft drilling rig is introduced into a shaft structure. The devices known from the two cited documents have the disadvantage that the operation of the respective shaft drilling device must be carried out by an operator in the shaft. The operator must thereby supply the shaft drilling machine in the shaft further linkage sections or remove boom sections. Typical manhole structures have an inside diameter of 1 m and a shaft access opening of 62 cm. As a result, the work for the operator in the shaft is very cumbersome, especially at low drilling depths, since the shaft diameter of conventional shaft structures decreases from 1 m shaft depth to the shaft access opening.

Shaft structures, which are also referred to in particular as manhole, inspection shaft or inspection shaft, serve for the review, maintenance and cleaning of pipelines. These manhole structures interrupt piping systems for contaminated, mixed or rainwater and are generally part of municipal wastewater disposal. They are usually made of precast concrete, masonry, fiber cement, polymer concrete or plastic and provided in the construction of piping systems at regular intervals of 40 m to 60 m. In many cases, the piping systems become wastewater disposal laid below streets. Starting from existing shaft structures, further media connections for buildings can be made via these shafts. In particular, starting from a shaft a building through a first horizontal well bore and retracted into this hole cable to the electric power grid, through a second horizontal well bore and a retracted therein cable with at least one communication network, by a third horizontal well bore and a drawn-in pipeline the gas supply network, connected by a fourth horizontal well bore and a drawn-in pipeline with a fresh water network and by a fifth horizontal well bore to the sewer network. For this purpose, it is necessary that the respective media are guided in the shaft structure. Through further horizontal drilling at least some of these media can be guided from manhole structure to manhole structure and connected in the manhole structures by suitable distributor with leading to the building to be connected lines. As a result, buildings can be connected to individual or all mentioned media as well as to other media without the need for any manhole work.

The object of the invention is to provide a method and an arrangement for producing and / or widening a hole in the ground or for replacing a pipe laid in the ground by means of a shaft drilling device, through which a simple operation of the shaft drilling machine is possible.

This object is achieved by a method having the features of claim 1 and by an arrangement having the features of the independent one Arrangement claim solved. Advantageous developments of the invention are specified in the dependent claims.

By a method for producing and / or widening a hole or replacing a pipe laid in the ground by means of a jig boring device and by an inventive arrangement is achieved that rocker sections introduced both by means of the transport device in the receiving area of the shaft drilling device as well as from the receiving area of the Schachtbohrgerätes can be removed without an operator must be in the shaft structure to insert rod sections in the receiving area of the shaft drilling or remove from the receiving area. This simplifies the operation of the shaft drilling machine with the shaft drilling device arranged in the shaft construction. In particular, a control station can be arranged outside the shaft structure, so that during the Erdbohrarbeiten no operator must be in the shaft structure.

It is particularly advantageous to provide above the shaft surface above the surface of the earth a boom with a plurality of boom sections, wherein an operator removes the boom sections the linkage supply individually and the transport device individually feeds and / or wherein the operator of the transport device removes a linkage section and feeds the linkage stock again. In an alternative embodiment of the invention, the boom sections of the transport device can be individually supplied automatically from the linkage supply with the aid of a boom section handling unit and / or automatically transported by the transport device to the linkage supply by means of the linkage section handling unit become. The linkage stock may each comprise at least one linkage magazine in the alternative embodiments.

Furthermore, it is advantageous to transport the boom sections during transport into the shaft structure with approximately horizontally oriented longitudinal axis through the shaft access opening, laterally offset the boom sections in a subsequent downward movement and introduce this lateral offset in the receiving area of the shaft drilling. Further, the boom sections during transport from the shaft structure during an upward movement from the receiving area of the shaft drilling to Schachtagangsöffnung be offset laterally with approximately horizontally oriented longitudinal axis by means of the transport device, so that they are aligned approximately centrally to the shaft access opening and transported therethrough. Generating the lateral offset is required in particular in manhole structures in which the central axis of the shaft does not run through the center of the shaft access opening but has a lateral offset to the center of the shaft access opening. The offset is particularly dependent on the orientation of the shaft drilling machine to the center of the shaft access opening and may be required both in the drilling direction, opposite to the drilling direction, transverse to the drilling direction or obliquely to the drilling direction. It is advantageous to align the elements of the transport device above the shaft structure, ie above the earth's surface, relative to the shaft access opening, so that the transport of the rod sections along the transport path of the transport approximately centrally through the shaft access opening and the offset in a range between manhole access opening and the shaft boring machine is effected by a corresponding course of the transport route.

It is particularly advantageous if the transport device has a transport carriage with a holding device for receiving a linkage section. In this case, the transport carriage can be guided by means of a provided between the Gestängezuführbereich and the shaft boring guide means and driven by means of a drive means. The guide means, which preferably comprises at least one cable, in particular two cables, and the drive means, which preferably comprises at least one drive motor and a drive chain or drive cable, are components of the transport route. If necessary, the transport path can comprise positioning means in order to position the guiding and / or drive means at least selectively in the shaft. With the help of the transport carriage, a linkage section to be transported can be kept simple and moved along the guide means. As a result, a simple handling and a simple construction of the transport device are possible. The length of the transport route is changeable. The change in length can be effected in particular by changing the length of the guide means, in particular the length of the cable sections of the cables forming the transport route, and the length of the drive chain. The length of the transport section forming cable sections can be done in particular by changing the clamping position of cable clamps, with which the cables are connected outside the shaft with a stationary holding device. The length of the drive chain can be changed by inserting or removing chain links, in particular chain sections with a plurality of chain links, wherein the chain is preferably formed of a plurality of sections each having a plurality of chain links. The sections are preferably connected to one another via known chain locks.

It is also advantageous if the holding device of the transport carriage has at least one clamping arrangement for receiving a linkage section. In this case, at least one clamping element of the clamping arrangement can be acted upon by a spring force, by which the linkage section is held in the clamping arrangement during transport. As a result, the linkage section can be easily inserted into the clamping arrangement and held there sufficiently securely.

In this case, the clamping element can partially enclose a region of the rod section. To release the linkage section from the clamping arrangement, the linkage section accommodated in the clamping arrangement can be introduced into the receiving area of the shaft drilling device and held there. With the help of the transport device, the clamping arrangement is then moved upward, so that the clamping arrangement is subtracted from the boom section held in the shaft boring machine. The clamping element is moved against the spring force. As a result, a simple handling, in particular an automatic release of the boom section from the clamping arrangement and thus the transport carriage, possible without intervention of an operator are required.

Furthermore, it is advantageous if the transport carriage has at least one guide region which, at least when reaching the lower end position of the transport carriage on the shaft boring machine, is engaged with a complementary element arranged on the shaft boring device, such that the transport carriage and thus the carriage held in the transport carriage engage Linkage section at the lower end of the transport path a reproducible defined target position relative has to the shaft drill. It is thus achieved that the linkage section is introduced into this desired position in the receiving area of the shaft drilling machine. Thus, a simple problem-free coupling of the rear end of the introduced into the receiving area of the shaft boring boom section with the shaft boring machine is possible.

Furthermore, it is advantageous if the transport carriage has a positioning element, by means of which a rear end of the rod section boring device introduced into the receiving area of the shaft boring device has a desired angular position relative to the rod receiving element of the shaft boring device. Thereby, the rear end of the introduced linkage section can be easily contacted by the linkage receiving element of the jig boring machine without operator intervention by an operator.

The clamping arrangement can have as a clamping element a spring-biased gripper, which is designed so that the rod section is held in a predetermined angular position. Alternatively, the linkage section can be received in the gripper in any desired angular position. If the already mentioned positioning element is then additionally provided, the linkage section can only be inserted into the gripper of the clamping arrangement in an angular position suitable for further handling. The positioning element can be designed as a separate component that is connected to the transport carriage.

In a further preferred embodiment, the by means of the transport device in the receiving area of the shaft boring machine used linkage section of the shaft drilling machine connected by means of a Renkverbindung with a rod receiving element of the shaft drilling machine. By the Renkverbindung at least one rotationally fixed in rotation and a tensile and shear-resistant connection between the rod receiving element and the introduced linkage section is made. This Renkverbindung can be made in particular without operator intervention of an operator in the shaft, so that the handling over the prior art is considerably simplified. In this case, the connection between the rod receiving element of the shaft boring device and the rear end of a rod section is considered as a tie-down connection, in which the rod receiving element and the rear end of the rod section are plugged together and then displaced relative to one another or rotated relative to one another. The Renkverbindung can be easily and quickly made or solved without tools. In particular, the connection between the rod receiving element and the rear end of the linkage may be designed as a bayonet connection.

For producing the Renkverbindung or for establishing an alternative connection between the rod receiving member and the rod receiving member facing the rear end of a receiving range of the shaft drilling device introduced into the rod section, a portion of the rod receiving member is pushed over the rear end of the rod section. The rod receiving member pushed over the rear end is rotated so that a connecting member of the rod receiving member and a connecting member of the rod portion are engaged. This allows a simple and secure connection between the rod receiving element and the rear end of the boom section are made without operator intervention by an operator are required.

Furthermore, it is advantageous to rotate the rod receiving element by means of a drive unit, preferably by means of a hydraulic motor. When the connection between the rod receiving element and the linkage section is established, the rotational movement of the linkage receiving element is transmitted to the linkage section. Upon connection of the linkage section with the further linkage sections of the drill string, the rotary motion is transmitted to the entire drill pipe and the tool located at the front end of the drill pipe.

The rod receiving element is preferably arranged on a displaceable in the drilling direction and opposite to the drilling direction slide. The sliding movement of the sliding carriage is generated by means of at least one drive unit and preferably transmitted via at least one pull chain on the sliding carriage, wherein the sliding movement of the sliding carriage is preferably guided over guide tubes or guide rails. As a result, both the rod receiving element can be pushed over the rear end of the rod section in a simple manner and thereby the connection between the rod section and rod receiving element can be made as well as a feed or retraction movement of the drill string are performed. Tensile and shear forces in the range of 20 kN to 60 kN or in the range of 2 t to 6 t can be generated with the aid of conventional shaft drilling machines.

Furthermore, it is advantageous if the shaft drilling apparatus has a boom blocking device, by means of which a linkage section which is at least partially inserted into the ground is blocked in an angular position and against a longitudinal displacement in the drilling direction or opposite to the drilling direction. When the linkage section is blocked, the linkage receiving element can be released from the rear end of the linkage section connected to the linkage receiving element. After releasing the rod receiving member from the rear end of the linkage section, the rod receiving member can be removed from the rear end of the linkage section so that another linkage section can be received in the receiving area of the shaft boring machine. Subsequently, a further linkage section is introduced by means of the transport device into the receiving area of the shaft drilling device. The rod receiving element is connected to the rear end of the other linkage section. The front end of the further linkage section is connected to the rear end of the linkage section held by the holding device.

To remove a first linkage section, the entire drill string is withdrawn with the aid of the shaft drilling device when the connection is made between the rear end of the first linkage section facing the linkage receiving element. The rear end of a second linkage section connected to the front end of the first linkage section is blocked by means of the linkage blocking device. In the blocked state of the second linkage section, the connection between the front end of the first linkage section and the rear end of the second linkage section is released. This connection is preferably made by a screw connection, which by blocking the second rod section and a rotational movement the first linkage section is completely dissolved. The first linkage portion is held in the holding device of the transport carriage and held by means of the positioning of the transport carriage both in a desired angular position and prevented from moving in the drilling direction or opposite to the drilling direction relative to the transport carriage. In this position of the first linkage section fixed by the positioning element, the linkage receiving element is rotated to a preset angular position in which the linkage receiving element can be pulled off the rearward end of the first linkage section. In this angular position of the first linkage section of the sliding carriage of the shaft drilling device is further shifted with the rod receiving element, so that the first linkage section can be released and transported by means of the transport carriage up through the shaft access opening. As a result, an easy handling of the boom sections is also possible with a removal of linkage sections from the receiving area of the shaft drilling machine, without operator intervention of an operator are required.

The transport device can cause both a lateral displacement of the rod section in the direction of the X-axis and / or in the direction of the Y-axis when transporting a linkage section between the shaft access opening and the shaft boring machine. The X-axis and the Y-axis preferably run in a plane parallel to the earth's surface.

It when the transport device provides a flexible transport path, which is pivotable in the direction of the X-axis and / or in the direction of the Y-axis in the shaft is particularly advantageous. Furthermore, it is advantageous if the transport route is extendable. This can be a used guide element and at least one drive element can be extended and / or used with variable usable lengths. Furthermore, in a first embodiment, the transport carriage can be moved back and forth along the transport path or, in a second embodiment, can be deflected about a lower and an upper axis, so that a continuous endless transport path is formed. In this second embodiment, a plurality of transport carriages may be arranged at a distance from one another, which each receive a single linkage section and transport from the linkage feed area to the receiving area of the shaft boring device and / or transport it from the receiving area of the shaft boring machine back to the linkage feeding area. Due to the simple construction, however, the first embodiment is particularly advantageous, in which only one transport carriage is present, which transports a linkage from the linkage feed area to the receiving area of the shaft drilling device and vice versa.

It is particularly advantageous if the shaft boring machine has sensors which detect the rod receiving element for receiving the rear end of the rod section in a predetermined rotational position, so that the rod receiving unit can be brought into this rotational position. This makes it possible that a portion of the rod receiving member can be pushed in this rotational position on the rear end of a linkage portion or withdrawn from this. Furthermore, it is possible to rotate a linkage section connected to the linkage receiving unit into a rotational position in which the linkage section can be received in the holding device of the transport carriage. In particular, in this position, a contact region of the linkage section can be brought into engagement with the positioning element of the transport carriage, so that the linkage section in a fixed Rotary position is held in the receiving area of the transport carriage.

Furthermore, the shaft boring machine may comprise sensors which detect the displacement position of the sliding carriage in order to detect at least one position of the sliding carriage. As a result, the sliding carriage can be positioned exactly in this position. Thus, a pulled out of the ground boom section can be positioned in the receiving area of the shaft drilling that the holding elements of the holding device of the transport carriage and preferably the positioning of the transport carriage contact a linkage section, before subsequently rotated the rod receiving member relative to the fixed in one position by the positioning linkage section and from withdrawn at the rear end of the linkage section to release the linkage receiving member from the linkage section and to allow transport of the linkage section by means of the transporting device up through the shaft access opening to the linkage section feeding region.

The shaft drilling machine according to the invention and the method according to the invention enable a controlled horizontal drilling in the ground. Such drilling is also referred to as HDD method. The shaft construction is in particular a manhole, preferably according to DIN 4045.

The arrangement for producing and / or expanding a bore hole or for replacing a pipe laid in the ground with the features of the independent arrangement claim can be developed in the same way as the method according to the invention, in particular by the features specified in the dependent method claims or corresponding device features.

Further features and advantages of the invention will become apparent from the following description which, in conjunction with the accompanying figures, the invention with reference to embodiments explained in more detail.

FIG. 1 shows a schematic perspective view of a well drilling assembly 10 with a slot 12 shown in section. A shaft boring machine 14 is in the shaft 12 through a shaft access opening 16 introduced through and hydraulically clamped on the required height for the planned hole in the shaft 12. Alternatively or additionally, a support may be provided below the shaft boring device 14 towards the shaft bottom 18, the height of which is preferably adjustable.

At the in FIG. 1 shown representation of the wellbore 10 is already a so-called special housing 21 has been passed through a previously introduced into the shaft wall opening 22. At the front end of the special housing 21, an asymmetrical drilling tool 24 is attached. The rear end of the special housing 21 is connected to a first linkage section 20. The drilling tool 24 and the special housing 21 can be rotated together with the one by one linkage portion 20 or a plurality of successively arranged a drill string forming linkage sections by means of a drive unit of the jig boring device 14.

Above the shaft 12 above the shaft access opening 16, a control station 26 is arranged. The operator (not shown) stands for the operation of the jig boring device 14 on a grid 28 and receives information about the well drilling assembly 10 via a control panel 30, in particular via the shaft drill 14, and can via operating lever of the control panel 30, the jig 14 and a transport unit for Serve transport of linkage portions 20 serving linkage pin 32. The linkage pin 32 has a drive motor 34 which drives a revolving chain 36 to which a transport carriage 38 is attached. The chain 36 is deflected on a held in a receiving unit of the shaft boring machine 14 gear 40. The drive motor 34 is connected via a holding element 42 with a out of the shaft access opening 16 upwardly extending support arm 44 is connected, wherein the holding element 42 on the support arm 44 is infinitely adjustable in height, so that the chain 36 can be brought by a height adjustment of the support member 42 to a desired chain tension. Furthermore, the linkage pin 32 comprises two guide cables 50, 52 which are guided by two guide tubes 46, 48 of the transport carriage 38 and which guide the up and down movement of the transport carriage 38 when the chain 36 is driven by means of the drive motor 34.

The lower ends of the cables 50, 52 are passed through in each case a conical positioning element 54, 56. The lower cable ends of the cables 50, 52 are connected to the shaft drill 14. Furthermore, the positioning elements 54, 56 are connected to the shaft boring device 14. In alternative embodiments, the lower ends of the cables 50, 52 may also be connected to the positioning elements 54, 56 and these to the shaft boring device 14.

During a downward movement of the transport carriage 38 as a result of a corresponding drive of the chain 36 by means of the drive motor 34, the guide tubes 46, 48 of the transport carriage 38 via the tapered at the upper end to the ropes 50, 52 positioning elements 54, 56, until the lower Ends of the guide tubes 46, 48 abut on a stop formed by the jig boring device 14. Thus, the positioning elements 54, 56 are at least partially inserted into the opening of the guide tubes 46, 48. Depending on the clearance between the guide tubes 46, 48 and the positioning elements 54, 56, the transport carriage 38 is thereby positioned in its lower end position relatively exactly to the shaft boring device 14. This position of the transport carriage 38 is determined by the positioning elements 54, 56 and the guide tubes 46, 48, in which the positioning elements 54, 56 are inserted, reproducible. As a result, a rod section 20a held in the carriage 38 as a result of the relatively rigid structural design of the transport carriage 38 has a desired defined position relative to the shaft drilling device 14 and is thereby positioned with sufficient accuracy in a receiving region 58 of the shaft drilling device 14. This can be a in FIG. 1 non-visible boom receiving unit of the shaft boring machine 14 contact the rear end of the supplied linkage section 20a and connected to this rear end.

The upper ends of the guide cables 50, 52 are guided through corresponding openings in the retaining element 42 and connected by suitable means, in particular by a respective terminal, with the retaining element 42. About such terminals, the length of the cables 50, 52 between the shaft boring device 14 and the support member 42 can be changed in a simple manner.

The control station 26 comprises a linkage stock 60, which is designed as a linkage magazine and in which a plurality of linkage sections 20, 20 a are stacked. An operator can remove a linkage section from the linkage stock 60 and in FIG. 1 shown inserted into a holding device of the transport carriage 38 in a defined angular position. The angular position is predetermined by contact surfaces provided on the linkage section 20, 20a and a positioning element 63 provided on the transport carriage 38, so that the linkage section 20a can be inserted into the receiving region of the holding device of the transport carriage 38 only in an angular position or in a deviating 180 ° angular position. The holding device 62 of the transport carriage 38 comprises a clamping device with two spaced-apart clamping areas with grippers which partially surround the linkage section 20a. At least one gripping element of each clamping area is pressed with a force against a region of the linkage section 20a, whereby the linkage section 20a is held by the holding device 62 in the transport carriage 38 in a horizontal orientation, ie with a horizontally oriented longitudinal axis or a horizontally oriented longitudinal axis of the linkage section 20a , This orientation of the linkage section 20a is also referred to as a lying position. During the transport of the boom section 20a of the in FIG. 1 shown position down into the receiving area 58 of the jig boring device 14, this lying position of the linkage portion 20a is substantially maintained. At least the linkage section 20a is inserted into the receiving area 58 of the shaft boring device 14 in this lying position, so that the longitudinal axis of the linkage section 20a is oriented approximately parallel to the drilling direction of the shaft boring device 14 and thus runs parallel to the direction of movement of the sliding carriage 64. In this orientation, the linkage portion 20a inserted into the receiving portion 58 of the jig boring machine 14 can be easily connected to a linkage receiving unit of the sliding carriage 64 and then to the rear end of the rear linkage section 20 forming the existing drill string.

The shaft boring device 14 comprises a substructure 66 which, as already mentioned, is positioned in a suitable manner on a height required for the borehole to be executed in the shaft 12, in particular in the shaft 12, braced. The drilling unit 68 is then positioned on this substructure. In this case, the drilling unit 68 is provided in it Receiving areas of the substructure 66 held. In addition to the stepless height adjustment of the holding element 42 relative to the holding arm 44, the holding arm 44 can be adjusted in height continuously in the present embodiment with respect to a set up on the surface of the earth frame 70 of the control station 26.

In other embodiments, an automatic linkage change may additionally be provided which automatically removes linkage sections 20, 20a from the linkage stock 60 and inserts them into the holding device of the transport carriage 38. Additionally or alternatively, this automatic linkage changer can also automatically remove linkage sections 20, 20a from the holding device of the transport carriage 38 and deposit them in the device supply 60.

FIG. 2 shows a further perspective view of the wellbore 10 after FIG. 1 , In this perspective, a display and monitoring unit 72 of a location system for locating the tool 24 is visible. With the aid of such a locating system, the position of the tool 24 and thus of the drill head of the drill string can be determined both in a plane parallel to the earth's surface and the depth of the tool 24 below the earth's surface. Preferably, the position of the tool 24 is determined in a three-dimensional coordinate system, preferably in a world coordinate system. If the position is repeatedly determined and preferably additionally adjusted with the feed path generated by means of the shaft boring device 14, not only the position of the tool 24 but also the course of the bore through the soil can be determined and recorded accurately. This record can be used in particular for documentation purposes, so that the course of the used in the generated well bore Management is simply documented and is known in later earthworks.

At the in FIG. 2 shown view is also a drive and deflection 74 visible. At least one end of the drive chain 78 is connected to the shift carriage of the drilling unit 68. Preferably, both ends of the chain 78 are connected at opposite sides to the shifting carriage of the drilling unit 68. Furthermore, in FIG. 2 the hydraulic connection of a linkage blocking device 80 visible with which the rear end of the linkage portion 20 can be locked in an angular position and against a displacement movement in the drilling direction or opposite to the direction of drilling. For this purpose, the displacement slide 64 of the drilling unit 68 is moved in a suitable longitudinal position for blocking the boom section 20 and a locking fork of the boom blocker device 80 applied with a force, so that this fork slides at a suitable angular position of the linkage section 20 at two opposite contact surfaces of the linkage section 20, 20a and prevents the linkage section 20, 20a from rotating and longitudinally moving in the direction of drilling or opposite to the drilling direction.

If, when activating the boom blocking device 80, the boom section 20 is not in an angular position which makes it possible to lock, the entire boom is further rotated by means of a drive unit of the drilling unit 68 until the correct angular position is reached. In this angular position, the blocking fork of the linkage blocking device 80 slides along the contact surfaces and blocks further rotational movement of the linkage section 20. Alternatively or additionally, the angular position of a linkage receiving unit of the drilling unit 68 are detected, in which the linkage portion 20 has reached the correct angular position. In the specific embodiment of the linkage sections and the blocking fork according to the described embodiment of the invention, blocking of the linkage section 20 in two angular positions offset by 180 ° is possible because the two contact surfaces, which are engaged by the blocking fork of the linkage blocking device 80, are arranged opposite one another. In other embodiments, only one contact surface can be provided, so that then the linkage portion 20 can be blocked only in an angular position. Also, instead of a blocking fork, another suitable engaging element may be provided, which can be brought into engagement with a complementary engagement area of the linkage section 20, 20a.

In FIG. 3 is a side view of the wellbore assembly 10 after the FIGS. 1 and 2 shown. In this illustration, the slide carriage 64, a guide tube 84 for guiding the sliding movement of the slide carriage 64 and the drive chain 78 of the drill unit 68 are shown. The drilling unit 68 further has two end plates 86, 88, which are interconnected by spacers 90, 92. Preferably, all of the drive units of the drilling unit 68, including the boom blocker 80 and the linkage pin 32, are hydraulic motors or hydraulic cylinders connected to a central hydraulic unit integrated with the operator station 26 or located adjacent to the operator station 26.

In FIG. 4 is another view of the wellbore assembly 10 after the FIGS. 1 and 3 shown, wherein the transport path, which is formed by the guide cables 50, 52 and the rotating drive chain 36, a lateral offset between the upper and lower starting point of Transport carriage 38 has. Like from the FIGS. 1 to 4 can be seen, the shaft 12 tapers in an upper portion to the shaft access opening 16, so that the central axis of the circular shaft 12 in the region of the drilling unit 68 and the center of the shaft access opening 16 have a horizontal distance. The linkage sections 20, 20a to be transported from above through the shaft access opening 16 to the drilling unit 68 by means of the linkage pin 32 are preferably transported approximately centrally through the shaft access opening 16 in the lying position already described above. The drilling unit 68 is positioned in the shaft 12 such that its receiving area 58 for receiving a further linkage section 20a is not exactly below the shaft access opening 16 shifted laterally to the central axis of the shaft, so that the linkage section 20a does not only retract after passing the shaft access opening 16 in the shaft 12 bottom but also with a lateral movement for generating a lateral offset, so that the linkage portion 20a is at least then arranged above the receiving portion 58 of the drilling unit 68 when the positioning elements 54, 56 are inserted into the guide tubes 46, 48. In a further lowering of the transport carriage 38 to the lower stop on the positioning elements 54, 56 and / or the drilling unit 68, the movement of the transport carriage 38 is guided at least by the positioning elements 54, 56 and the guide tubes 46, 48.

In FIG. 5 is a side view of the wellbore assembly 10 after the FIGS. 1 to 4 shown, wherein the transport path formed by the guide cables 50, 52 and the chain 36 of the linkage pin 32 one of FIG. 4 having a different lateral offset. In the in FIG. 5 Side view shown are the drive shaft 74 and the drive chain 78 and the parallel drive chain 79 for driving the sliding carriage 64 visible. Further, a sprocket 94 rotatably connected to the shaft 74 is shown engaged with a hydraulic motor 94.

In FIG. 6 is a side view of the wellbore assembly 10 after the FIGS. 1 to 5 shown, wherein the transport path of the linkage pin 32 one of the FIGS. 4 and 5 has a different offset. In FIG. 7 is a further illustration of the wellbore 10 after the FIGS. 1 to 6 shown, wherein the shaft drilling unit 68 is positioned by means of the substructure at a greater depth than in the FIGS. 1 to 6 , Furthermore, a straight transport path of the linkage pin 32 is shown. This transport path can be aligned by subsequent displacement of the control station 26 or by a part of the control station 26 such that a linkage section 20a is guided substantially centrally through the shaft access opening 16. This is based on the in FIG. 7 shown arrangement of the transport path to provide the lateral offset by the clamping devices of the guide cables 50, 52 are dissolved in the support member 42 and extended by the required length. Furthermore, the chain 36 is to be extended accordingly. Alternatively or additionally, the position of the holding element 42 on the holding arm 44 can be changed by the holding member 42 is moved down on the holder arm 44 and so the transport path between the in FIG. 7 shown upper position of the transport carriage 38 and the drill 14 is extended.

In FIG. 8 is a perspective view of a linkage section 20, 20 a shown. At the front end of the linkage section 20, 20a, an external thread 96 is provided, which serves for connecting the linkage section 20, 20a with a further linkage section. Alternatively, the Linkage section 20, 20a are connected at the front end with a drilling tool 24 and / or a probe. The linkage section 20, 20a has a tapered central region 98, which is contacted by the holding device of the transport carriage 38 for transporting the linkage section 20, 20a, in which gripper elements of the holding device 62 surround part of the region 98. At the rear end of the linkage portion 20, 20 a tapers 156, 158, 160 for establishing a recessed connection between the linkage portion 20, 20 a and the drilling unit 68, especially a rod receiving unit of the drilling unit 68. In the rear area between the recesses 156, 158, 160 for the Renkverbindung and the tapered central region 98, two opposing contact surfaces 102 are shown, of which FIG. 8 only one surface 102 is visible. Due to their function, these contact surfaces 102 are also called positioning surfaces 102. To produce this positioning surface 102, a recess has been made in the circular cross section, so that the circular cross section is flattened in the region of the positioning surface 102. As a result, a fork-shaped positioning element 63 can be pushed laterally onto the positioning surfaces 102, much as an open-end wrench can be pushed onto the contact surfaces of a hexagon nut or hexagon screw.

In FIG. 9 is a further perspective view of the linkage section 20, 20a after FIG. 8 shown. In this illustration, the internal thread 104 is visible at the rear end of the linkage section 20, 20a. In this internal thread 104, the front external thread 96 of another linkage section can be screwed, so that these linkage sections can be connected to one another via a screw connection produced in this way. About this screw a plurality of rod sections 20, 20a are assembled into a drill pipe. At the Retreat of a drill pipe thus produced, the boom sections are then separated again by the screw connections between the linkage sections are released.

In FIG. 10 an enlarged view of the holding device 62 together with the positioning element 63 is shown. The holding device 62 is firmly connected to the transport carriage 38. A linkage section 20, 20a is inserted from below into the holding device 62. In this case, the positioning surface 102 contacts the inner side 63a of the first leg and the opposite positioning surface the inner side 63b of the second leg of the positioning 63. Here, the linkage portion 20, 20a with substantially vertically arranged positioning surfaces 102 is pushed from below between the legs of the positioning member 63. In this case, the spring-biased gripping arms 106 to 112 of the holding device 62 are pressed apart when the central region 98 of the rod section 20, 20 a through the formed by the shape of the gripper arms 106 to 112 tapered portions 114, 116 is passed therethrough. After passing the central portion 98 through the tapered portions 114, 116, the gripping arms 106 to 112 are retracted by means of the spring force generating springs 118, 120, so that the linkage portion 20, 20a securely into the receiving areas formed by the gripping arms 106 to 112 122, 124 is held.

In FIG. 11 is a further perspective view of the holding device 62 according to FIG. 10 shown.

In FIG. 12 is a perspective view of the holding device 62 according to the FIGS. 10 and 11 shown with a recorded in the holding device 62 linkage portion 20, 20a. It can be seen that the legs of the positioning element 63 contact the positioning surfaces 102 of the linkage section 20, 20a. The linkage section 20, 20a can thus in the in FIG. 12 shown position or in a rotated by 180 ° about its longitudinal axis position in the holding device 62 are used. The recesses 156, 158, 160 for producing the recessed connection between the linkage section 20, 20a and a linkage receiving unit of the drilling unit 68 are arranged offset on opposite sides by 180 °.

In FIG. 13 is a further perspective view of the holding device 62 with a arranged below the receiving area of the holding device 62 linkage portion 20, 20a shown. The receiving area of the holding device 62 is formed by the clamping arrangements and the positioning element 63. The in FIG. 13 shown linkage portion 20, 20a is aligned so that it can be inserted from below into the receiving area of the holding member 62 in this orientation, so that the positioning surfaces 102 between the inner surfaces 63, 63a of the positioning member 63 can be inserted.

In FIG. 14 the sliding carriage 64 of the drilling unit 68 is shown. In this case, a rod receiving unit 130 projects from a base plate 132 of the sliding carriage 64 in the direction of the receiving area 58 for receiving linkage sections 20a, 20b of the drilling unit 68. This linkage receiving unit 130 can be driven in the direction of arrow P 1 and in the opposite direction of rotation by means of the hydraulic motor 134, so that a drill pipe and / or a linkage section 20, 20a connected to the linkage receiving unit 130 are rotated together with the linkage receiving unit 130 or the linkage receiving unit 130 relative to a linkage section 20, 20a are rotated, when this linkage section 20, 20a is held in particular by the positioning element 63. The base plate 132 of the sliding carriage 64 is guided on guide rods 82, 84, which are arranged between the side plates 86, 88 and held by these. Further, on each side of the base plate 132, two protruding connecting elements 140, 142 are provided, with each of which one end of the drive chains 78, 79 is connectable. The other end of the respective chain is connected to a connecting element 144, 146 projecting on the opposite side of the base plate 132. The rotational position of the rod receiving unit 130 may be in the in FIG. 14 shown position detected by the sensor 148. With the aid of a further sensor 150, as in connection with FIG. 16 will be explained in more detail, a further rotational position of the rod receiving unit 130 are detected. If a linkage section 20, 20a is located in the receiving area 58 of the drilling unit 68 and is still held there by the holding device 62 of the transport carriage 38, the linkage receiving unit 130 can be guided over the rear end of the linkage section 20, 20a by a movement of the sliding carriage 64. Two engagement elements 152, 154 of the rod receiving unit 130 are thereby over flattened portions 156, 158 at the rear end of the rod section, which in FIG. 9 designated 156, 158, led away, so that they reach the subsequently formed as a groove area 160. When the slide carriage 64 has been displaced toward the front end of the linkage section 20, 20a such that the engagement elements 152, 154 are positioned opposite the two opposing grooves 160, the linkage receiving unit 130 may be rotated in the direction of rotation P1 until the engagement elements 152, 154 reach the end region 160a of the groove 160 have reached. If an opposite direction of rotation is desired, the rod receiving unit 130 is driven in the opposite direction of rotation, such that the engagement elements 152, 154 reach the opposite end 160b of the groove 160. By the lateral flanks of the groove 160 and a tensile and shear-resistant connection between the rod receiving unit 130 and the linkage portion 20, 20a is achieved when the engagement elements 152, 154 have reached the groove end 160a or the groove end 160b.

In FIG. 15 3, a perspective view of the sliding carriage 64 is shown, with the rod receiving element 130 having the same angular position as in FIG FIG. 14 ,

In FIG. 16 is another front view of the sliding carriage 64 shown with the rod receiving unit 130 in a second angular position. This second angular position can be detected with the aid of the sensor 150. The sensors 148, 150 are designed as inductive sensors, which detect in the present embodiment, a laterally projecting screw when it is in the detection range of the inductive sensors. However, other sensors, in particular a rotation angle sensor or an optical sensor, for detecting the position or the angular position of the rod receiving element 130 may alternatively or additionally be used.

In FIG. 17 is another perspective view of the sliding carriage 64 after the FIGS. 14 to 16 shown, wherein the rod receiving unit 130, the in FIG. 16 has shown second angular position. This second angular position is in particular the angular position in which the positioning surface 102 is aligned approximately vertically in the locked state between the rod receiving unit 130 and a linkage portion 20a, so that the positioning member 63 by a downward movement the transport carriage 38 can be brought into contact with the positioning surfaces 102. By means of these positioning surfaces 102, the angular position of the linkage section 20, 20a is fixed, so that by rotation in the direction of the arrow P 1 up to the in FIG. 14 shown position, the rod receiving member 130 and the linkage portion 20, 20a are unlocked. Thereby, the rod receiving member 130 at the end of the linkage portion by a further displacement of the sliding carriage 64 can be deducted from the rear end of the linkage portion 20, 20a.

In FIG. 18 is a perspective view of the drilling unit 68 with the sliding carriage 64 shown. The drilling unit 68 includes two more in FIG. 18 shown sensors 162, 164, which are also in the present embodiment as inductive sensors, so-called induction sensor, executed and each detect a shift position of the sliding carriage 64. As from the in FIG. 19 magnified representation of the area A, the sensors 162, 164 generate a corresponding position signal when a corresponding elevation 166, 168 is positioned in the detection range of the sensors 162, 164.

In FIG. 20 is shown a further perspective view of the drilling unit 68, wherein in this illustration, the drive motor 170 for generating the feed and return movement of the sliding carriage 64 is visible. Furthermore, further sensors 172, 174 and a position 176 which can be detected by the sensor 172 and marks a position along the displacement path are shown. In FIG. 21 is an enlarged view of the in FIG. 20 B shown area with the sensors 172, 174 for detecting feed positions of the sliding carriage. at In other embodiments of the invention, the drilling unit 68 may include further sensors for detecting further feed positions or fewer sensors for detecting feed positions when less position information is required to control the drilling unit 68.

Also, a plurality of sensors may be provided for detecting the position of the same position, in particular to allow a fail-safe and / or highly available detection of feed positions. This minimizes the risk of failure and increases operational safety.
