Definitions
- the invention relates to a double pipe linkage, a Doppelrohrgestfite- shot and a method for forming an electrically conductive connection in a double pipe linkage.
- a drill head When drill-based drilling in the ground, in particular for the production of so-called horizontal bores, a drill head is driven by a drill string from a arranged on the earth's surface or in a pit drive device.
- the drill pipe used in this case consist of individual, interconnected rod sections, which - according to the course of drilling - gradually attached to the rear end of the already drilled drill string and connected to this.
- a Doppelrohrgestlinde or double linkage is used for rock drilling, i. a drilling in rock or rocky earth formations.
- the drill head is additionally rotatably driven via an inner linkage of the double pipe linkage by the drive device arranged on the earth's surface or in the excavation, which also provides for the propulsion of the drill head.
- the inner rod is rotatably mounted within an outer linkage of the double pipe linkage.
- the individual rod sections of both the outer linkage and the inner linkage are either screwed together or inserted into each other.
- CONFIRMATION COPY To supply electrical consumers in the double pipe linkage and / or for the transmission of signals there is a need to provide electrical connections in the double pipe linkage.
- a disadvantage of the previous provision of electrical connections is that the electrical connection for the conduction of electrical energy - for an electrical voltage or power supply and / or transmission of data - can only be done in the inner tubular frame, as previously assumed that the conductor or the cable in the inner pipe string must be protected.
- the invention has for its object to provide an improved double pipe linkage, an improved Doppelrohrge- stSheschuss and an improved method for forming an electrically conductive connection in a double pipe linkage section, in which also an electrical connection in the annulus between inner pipe linkage and Outer tube rod is possible.
- the core idea of the invention is to lead out the at least one conductor provided in the inner linkage section from the inner linkage section in such a way that a customer present in the annular space between inner linkage section and outer linkage section is in contact with an external contact formed on the inner linkage section.
- an outer contact is formed, which is formed substantially annular around the circumference of the inner rod portion.
- the external contact can be electrically connected to the at least one conductor of the inner rod section and the electrical signal or the current or voltage can be tapped by means of the existing in the annular space between the inner rod section and outer rod section pickup as the customer is in contact with the annular outer contact of the inner rod ,
- the outer contact is formed substantially annularly around the circumference of the inner rod section, which comprises the outer contact being formed closed around the circumference of the inner linkage along the circumference.
- the extent of the external contact in the longitudinal direction of the inner linkage or inner linkage section can have any desired shape.
- the external contact can be configured as a band laid around the inner linkage section.
- the tape can go along the Scope have an equal width.
- the extension of the pickup in the direction of the longitudinal axis of the inner linkage is preferably equal to or smaller than the extent of the outer contact in the longitudinal direction of the inner linkage.
- the double pipe linkage section may be a double pipe linkage section of an earth boring device.
- section encompasses a region of the double pipe linkage in the longitudinal direction.
- linkage section can be understood to mean a "linkage.”
- An "earth boring device” is understood in particular to mean any device which converts a double pipe linkage into an existing or to be created channel in the ground moved to create a bore, in particular a horizontal bore, or widen or to draw lines or other long body in the ground.
- the earth boring device may in particular be an HD device (horizontal drilling, horizontal boring).
- conductor in the sense of the invention comprises an electrically conductive conductor, which in particular can be designed as a cable, that is to say with at least partially existing insulation which surrounds the conductor.
- drilling fluid can be conveyed at least in sections through the interior of the inner linkage and / or the annular space between inner linkage and outer linkage. This creates difficult conditions for the transmission of electrical signals.
- the at least one conductor is sealed in the region of the annular outer contact in the inner rod section.
- the term "sealed" in the sense of the invention comprises a sealing area in relation to the drilling fluid present at least in sections in the double tube linkage
- a pressure relief is performed by before this region or before the sealant at least one through hole in the inner rod is present, which creates a fluidic connection between the interior of the inner rod and the annular space between inner rod and outer rod.
- the outer region of the inner rod section is sealed in the region of the outer contact by means of sealing elements spaced apart in the longitudinal direction of the double tube rod section. This makes it possible to prevent electrical currents from occurring via the drilling fluid, which is present in sections at least in the double pipe rod.
- the pickup is sealed to the annulus between the inner string section and outer link section so that undesirable electrical (leakage) currents can be reduced.
- the outer contact is electrically insulated from the inner rod section.
- an insulating layer which may be designed as an insulating sleeve, may be present between the external contact and the internal linkage.
- the external contact can be connected in a rotationally fixed manner to the internal linkage via the insulating layer.
- a Doppelrohrgestfiteschuss which comprises an aforementioned double pipe section, which has a present in the annular space between the inner rod and outer rod probe.
- the probe may be connected to the outer rod and be connected by at least one conductor to the customer.
- an electrically conductive connection in a double tube linkage, wherein the electrically conductive connection is formed between an interior of an inner linkage section and the annulus between the inner linkage section and outer linkage section.
- a substantially annular outer contact is provided on the inner linkage and a conductor provided in the interior of the inner linkage is connected to the outer annular contact, with a male contact in contact with the outer contact disposed in the annular space in conductive contact via the outer contact to be led.
- Fig. 2 is a partial sectional view of Fig. 1;
- Fig. 3 is a sectional view of an enlarged portion of Fig. 2;
- Fig. 4 shows a further enlargement of Fig. 3 in a partial view.
- FIGS. 1 and 2 show a double pipe linkage in a front area.
- FIGS. 1 and 2 show a double pipe linkage section 6 with an outer linkage section 1 and an inner linkage section 2, wherein an electrical connection is produced from the interior of the inner linkage section 2 to the annular space 4 between inner linkage section 2 and outer linkage section 1.
- a probe eccentrically present in the double pipe linkage 3 can be supplied with energy and / or data.
- a transmission of energy and / or data in the direction of the probe 3 and / or bidirectionally to the probe 3 and from the probe 3 is possible.
- the double pipe linkage section 6 may enable the function of transmitting energy and / or data between the interior of the inner linkage and the annulus 4 between inner linkage and outer linkage.
- the probe 3 is located in a probe housing, which is connected to the outer rod.
- the inner linkage can rotate independently of rotational movements of the outer linkage within the outer linkage and drive a drill head. About the rotation of the outer rod a desired drilling direction can be adjusted.
- the moving together with the outer rod probe 3 can here certain values, such as the roll angle or the inclination of the double pipe linkage, detect and transmit to a known from the prior art further unit.
- the transmission can be wireless and / or wired.
- a conductor 8 or a cable is guided (cf., Fig. 3), via which the transmission of data and / or energy can take place.
- the conductor 8 or the cable is guided via a bore to the outside and electrically connected to an annular outer contact 10, which is designed as a slip ring.
- the annular outer contact 10 has an electrically insulating sleeve 16 which sits firmly on the inner rod section. As a result, the annular outer contact with respect to the inner rod section is electrically isolated.
- the executed from the inner rod section conductor is clamped with the annular outer contact, for which in the illustrated embodiment of Figures 3 and 4, a screw 11 is used.
- an electrically conductive pickup 13 in contact.
- several customers 13 can be used.
- the one or more customers 13 are arranged in an insulating sleeve 17 made of non-conductive material.
- another conductor 14 is connected to the probe 3 can be connected.
- the pending on the conductor 8 energy or pending data can be transmitted to the other conductor 14.
- drilling fluid is initially conveyed via the annular space 4 between inner linkage and outer linkage as well as through the interior of the inner linkage, in order to avoid pressure losses due to the increasingly long double pipe linkage.
- Drilling fluid is discharged in the direction of the drill head, in front of the double pipe section, in which the electrical connection between the at least one conductor 8 and the external contact is made by outwardly leading holes 7 in the inner rod, resulting in that the drilling fluid from the inner rod on the last section to the drill head is also passed over the annulus 4.
- behind the holes 7 of the double pipe linkage section is a sealing of the inner rod located and co-rotating with this conductor 8 against the upcoming Bohrroughkeitstik by means of a sealant.
- the section of the double pipe linkage in the region of the annular outer contact is sealed off by means of two sealing elements 12 which are spaced apart in the longitudinal direction of the double pipe link section and which are designed as sealing rings. Furthermore, a further sealing means 15, which is designed as a sealing ring, is present, which encloses the further conductor 14.
- the one or more customers 13 is rotatably connected to the outer rod portion, whereby a rotational movement is prevented relative to the outer rod.
- There is a torque arm 18 is present, which prevents rotation of the customer or 13.
- the customer or the buyer 13 are guided over the annular outer contact, following the rotational movement of the outer linkage.
