Definitions

the invention relates to a BohrgestCodeschuss, a connection system of a Erdbohrvortechnisch, a Erdbohrvortechnisch and a method for connecting a BohrgestSheschusses.
Erdbohrvoridesen in particular horizontal drilling, are used to bring in trenchless construction Erdbohritch example for supply and disposal lines in the ground or already laid old lines trenchless exchange.
a Bohrgestfiteschadore exhibiting drill string is usually used in which the BohrgestSheschadore with each other, with drill heads and / or a drive can be connected.
BohrgestCodeschadore it is known to design BohrgestCodeschadore such that the BohrgestCodeschadore have an internal thread at one end and are provided at the other end with an external thread.
a BohrgestCode with its male thread end having in a corresponding internal thread in another BohrgestCodeschuss - or vice versa - be screwed.
a disadvantage of the known prior art is the use of an additional component - the transverse pin - to produce a rotationally fixed connection in both directions of rotation about the longitudinal axis of Bohrgestfiteschadore. It requires additional material and additional process steps to connect the drill string and loosen it after creating the wellbore. In particular, the removal of the cross pin may be difficult and / or time consuming due to the harsh conditions of earth boring.
the invention therefore an object of the invention to provide an improved Bohrgestfiteschuss, with a simpler design of a rotationally fixed connection in both axial directions of rotation is possible. Furthermore, an improved connection system and an improved earth boring device should be provided. Furthermore, a method should be specified, with which an improved connection of a drill string is possible.
the idea underlying the invention is to develop a bayonet connection, which consists of a plug-in rotary connection, such that in addition to the steps of plugging and turning another plug-in step is performed by a rotationally fixed connection about the longitudinal axis of BohrgestSheschusses is reached.
a paddle operation of the drill string is possible in particular.
a “drill string” in the context of the invention comprises a rod section of an earth boring device.
a “Erdbohrvortechnisch” is in particular any device understood that a BohrgestCodeschadore having BohrgestCode moved in an existing or to be created channel in the ground to create a bore, especially a horizontal bore, or widen or retract lines or other long body in the soil ,
the earth boring device may in particular be an HD device (horizontal drilling, horizontal drilling).
An inventive “Erdbohrvortechnisch” comprises a a drill pipe driving device that works soil displacing, and the drill string at least over a partial angle range rotating in the longitudinal axial direction of the drill string can be driven. If the linkage is moved over an angular range in both directions of rotation in the direction of the longitudinal axis of the drill pipe, this is referred to as paddle operation.
HD in the context of the present invention includes in particular any type of existing or to be created, preferably horizontal or inclined to the horizontal channels in a body, in particular earth channels including earth boreholes, rock holes or ground lines and underground or above-ground pipelines and water channels, through Use a suitable Erdbohrvorraum produce or pull.
An inventive BohrgestSheschuss has at least, in particular end, a plug-rotary recording, a so-called bayonet mount, for cooperation with a driver, the so-called bayonet driver on.
the receptacle allows an additional plug-in step for fixing the spreader in a rotationally fixed in both directions of rotation connection about the longitudinal axis of the BohrgestSheschusses.
the receptacle which in particular can be arranged at the end on the drill string section, enables the drill string section to be set into one another with the catch by means of a plug, the drill string section and the catch being aligned with one another in the longitudinal axial direction of the drill string section.
the receptacle allows another mating step, especially in the longitudinal axial direction of the drill string, to cause the surfaces cooperating during rotation (in the rotating step) to become out of alignment and twisting Rotation to form the connection no release of BohrgestCodeeschusses from the driver allows.
BohrgestCodeTec and drivers can be fixed so that a rotationally fixed connection about the longitudinal axis of the BohrgestSheschusses in both directions of rotation is possible.
drill string and driver can be aligned so that BohrgestCodeTec and driver have cooperating surfaces that in plant get to each other at the additional plug-in step, and fix BohrgestCodeeschuss and driver rotationally fixed in both directions of rotation.
An inventive Bohrgestfiteschuss thus allows a simple embodiment of a compound with a driver, in which a rotational movement of the BohrgestSheschusses in both directions of rotation about the longitudinal axis of BohrgestSheschusses is possible.
the Bohrgestfiteschuss a way to recover the linkage by means of a pulling movement, since by forming a rotation between Bohrgestlindeschuss and driver and prior alignment and plugging Bohrbarfiteschuss and driver to each other, the driver can be rotated relative to the Bohrgestfiteschuss, so that an inner contour of Driver and an outer contour of a Bohrgestfiteschusses are no longer aligned.
a possible rotational movement for releasing in one direction namely in the direction for forming the connection in the rotational step is possible.
the driver may be formed on a Bohrgestfiteschuss invention, so that the driver is formed at one end of a Bohrgestfiteschusses and a corresponding receptacle for the driver at the other end of the Bohrgestfiteschusses. But it can also be provided that the Bohrgestfiteschuss only at one end has a receptacle for the driver. In particular, it may be provided that a drill string section provided at the front end of the drill string and connected to the drill head has a receptacle for the catch at only one end and a different type of connection is provided at the other end.
a further connecting element is formed at the end region of the BohrgestSheschusses on which the (bayonet) receptacle is formed.
a conical thread can also be formed, by means of which the drill string sections can be screwed together and the driver is formed only on the drive or a carriage of an earth drilling device.
the recording of the drill string according to the invention comprises in a preferred embodiment an alignment section, a rotary section and a paddle section on.
the three sections of the receptacle may allow the individual steps to form the connection, ie insertion, rotation and insertion.
the alignment section the BohrgestSheschuss and the driver can be aligned axially, so that plugging can be done after aligning each other.
the rotary portion of the Bohrgestfiteschuss and the driver can be rotated relative to each other about the longitudinal axis, preferably by 45 °.
the paddle section allows for the relative rotation of Bohrbarfiteschuss and driver required plugging of Bohrgestfiteschuss and driver relative to each other.
the plugging in the sense of the invention takes place by a relative movement of BohrgestCodeTec and driver in the axial direction towards each other.
the paddle section are in both directions of action of the BohrgestSheschusses and the driver before, which are in contact with each other to ensure the rotationally fixed connection in both directions of rotation.
the alignment section is more closely spaced than the pivot section and the paddle section with respect to the end of the drill string at which the connection is formed.
the rotary section is spaced closer to the end of the drill string section where the connection is to be formed than the paddle section.
aligning section, rotating section and paddle section can follow each other directly from the end of the drill string section where the connection is to be formed.
the receptacle has an axial seating surface and a paddle surface for the driver.
the axial Mausitz Structure is a the driver or the end of the BohrgestSheschusses facing surface against which the driver reaches the additional plug-step in abutment with a surface and finished the movement during the insertion step between BohrgestSheschuss and driver.
the paddle surface for the driver ensures the rotation-resistant connection, wherein the driver rests with a corresponding surface on the paddle surface.
the seating surface may in particular have a surface normal which runs parallel to the longitudinal axis of the drill string section.
the paddle surface may in particular have a surface normal which is parallel to a radial direction.
two paddle surfaces are formed on BohrgestCodeschuss, which are arranged angularly offset from the longitudinal axis of the BohrgestCodeTeces.
the formation of two paddle surfaces a safe training of the rotationally fixed connection in the two directions of rotation is possible. For every the two directions of rotation may be provided a paddle surface for the driver.
a portion for longitudinal axial alignment of the BohrgestSheschusses to the driver is formed (alignment portion) in an angular range about the longitudinal axis of Bohrbarlindeschusses a projection relative to another portion in which the driver is rotatable about the longitudinal axis of the Bohrgestfiteschusses (rotary section).
the projection may be configured such that the driver prevents a stop for axial movement of the driver for Bohrgestfiteschuss after the relative rotation of the driver to the Bohrgestfiteschuss.
the term "projection" may include a macroscopic projection on a peripheral surface of the drill string section. The macroscopic elevation may preferably be localized.
the survey may protrude from the surface.
the projection may protrude with respect to a lateral surface of the rotary section.
four projections may be formed.
the section for longitudinal axial alignment of the BohrgestCodeTeces is preferably formed symmetrically, so that one or more existing projections which are provided as a stop for limiting an axial relative movement between BohrgestCodeeschuss and driver are angularly offset from each other winkeläquidistant formed about the longitudinal axis of Bohrgestfiteschusses.
the portion in which the driver is rotatable about the longitudinal axis of the drill string has a longitudinal movement stop surface and a rotation stop surface disposed relative to each other such that the driver contacts with the rotational movement stop surface is out of contact with the longitudinal movement stop surface and the driver is pluggable relative to another portion (paddle portion).
the invention also provides a connection system of a Erdbohrvorraum for connecting an aforementioned BohrgestSheschusses with a driver and a Erdbohrvortechnisch with one of the aforementioned BohrgestSheschadore.
the invention provides a method of connecting a drill string to a driver, the method comprising the steps of: inserting the drill string relative to the driver in the longitudinal direction of the drill string, rotating the drill string relative to the driver about the longitudinal axis of the drill string and inserting the drill string relative to the driver in the longitudinal direction of the Bohrgestfiteschusses, wherein the driver is brought into contact with the BohrgestCodeeschuss such that a rotationally fixed connection is formed in both directions of rotation to the longitudinal axis of the Bohrgestfiteschusses.
