Definitions
- the invention relates to a ram boring apparatus according to the preamble of claim 1 and a method for operating a corresponding ram boring apparatus according to the preamble of claim 13.
- ram boring apparatuses are known from the prior art and are used in particular for the production of horizontal boreholes.
- Rammbohrvorraum has a percussion piston, which is oscillating (reciprocating) within the housing and thereby, depending on the desired direction of movement of the ram boring device, bounces on a front or rear impact surface of the housing.
- the transmitted kinetic energy of the percussion piston ensures an acceleration of the ram boring device within the soil.
- the local ram boring device has a control tube with a percussion piston movably mounted thereon.
- the control tube is fixed at its rear end with a compressed air supply and further connected both longitudinal axial and rotationally movable via a prestressed coil spring with a housing-fixed component.
- the spring forces the head tube into a forward position (pre-run position) and locks it in this position by a quarter turn in a locking groove.
- the control tube is unlocked by a quarter turn of the compressed air supply against the spring bias, so that the control tube under the influence of compressed air and against the longitudinal axial spring force in a rear position (return) is moved.
- the device of DE 39 09 567 A1 thus discloses two operating positions in which either a front or a rear impact surface of the housing is acted upon.
- the invention is based on the object of improving a ram boring device such that the impact frequency and / or the impact intensity can be influenced. This object is achieved by the subject matter of the independent claims.
- the invention provides for a ram boring device for creating horizontal bores of the type mentioned above to be provided with a device which makes it possible to displace the middle position of the percussion piston in such a way that the frequency of the percussion piston movement and / or the impact intensity is varied.
- ram boring is meant, in particular, any device which is moved intermittently in an existing or to-be-created channel to create or expand a bore or destructively or non-destructively replace or clean an existing pipe, conduits in existing pipes or other long bodies as well as all devices for construction work of underground tunneling.
- the ram boring device according to the invention is not limited to underground earthworks.
- lines in which a Erdbohr réelle is operated run above ground.
- the term "horizontal drilling" in the sense of the present invention covers in particular any type of existing or to be created, preferably horizontal Ducts in a body, in particular earth channels including earth bores, rock holes or earth pipes and underground or above-ground pipelines and sewers, which can be produced, widened, destroyed, cut or cleaned by using a corresponding ram boring.
- “Middle position” of the percussion piston is understood in the context of the invention, the position which is located centrally between the two reversal points of the oscillating movement of the percussion piston.
- this has, in addition to the housing and a percussion piston, which is displaced via a supplied pressurized fluid, thus a gas or a liquid, in an oscillating movement taking place within the housing, further comprising a control sleeve which is movable within the Impact piston is arranged.
- the percussion piston is characterized by at least one control opening in his coat, the position of the
- Control opening before, above and behind the control sleeve causes the alternating ventilation of a pressure chamber located between the housing and the percussion piston.
- the displacement of the central position of the percussion piston can be effected by a change in length (extension, shortening) of the control sleeve and / or by a displacement of the position of the control sleeve within the housing.
- One way to change the position of the control sleeve may be to use the control sleeve with a back side, i. in the direction of the connection for a Druckfluid- feed with a guide sleeve to connect, which is itself either extended / shortened or displaced within the housing to achieve via the connection with the control sleeve, the inventive displacement of the mean position of the percussion piston.
- the position of the control sleeve can also be changed in that it is displaced via the connecting element relative to the guide sleeve.
- control sleeve or the "guide sleeve” to be tubular. Rather, any shape is possible through which the intended function can be fulfilled.
- a length-adjustable control or guide sleeve may have at least two sub-sleeves which are movable relative to each other in at least axial axial direction and by their position relative to each other define the length of the control or guide sleeve.
- the sub-sleeves are formed such that one of the sub-sleeves is slidably mounted on another partial sleeve.
- the second part of a sleeve Having reduced outer diameter portion which substantially corresponds to the inner diameter of the first sub-sleeve.
- a device for adjusting the relative position of the two sub-sleeves can be further provided to each other. This can be an adjustment in both
- elastic means are preferably provided, which are arranged between the two sub-sleeves and cause a restoring force against the adjusting force of the device.
- the elastic means may e.g. also on the opposite side of one or both
- the device also allows to adjust the two sub-sleeves to each other during the beating operation.
- the function of the adjusting device can be based on various physical principles.
- the adjusting force can be generated by hydraulic, pneumatic or magnetic means.
- purely mechanical adjustment options are possible, for example via a driven relative rotation in conjunction with a thread-shaped connection of the two sub-sleeves. Of course, combinations of the above adjustment can be used.
- the length-adjustable control or guide sleeve is designed or fixed such that a change in length of the control sleeve only causes a displacement of the sleeve edge, which faces away from the impact surface of the housing acted upon.
- the control sleeve edge, which is located on the side of the impact surface of the housing is thus arranged (in an operating position (forward / backward) of the ram boring device) fixed within the housing.
- a device according to the invention for displacing the position of the control or guide sleeve within the housing preferably comprises a control tube, which extends at least in one section within the control or guide sleeve and is movable in at least longitudinal axial direction.
- a movable to the control sleeve trained control tube is preferably fixedly connected to the housing.
- control tube (at least in the longitudinal axial direction) connected to the control sleeve and movably mounted within the guide sleeve, whereby a displacement of the control tube relative to the guide sleeve leads to a displacement of the control sleeve
- the relative position of Control ear in the guide sleeve fixed in several positions, whereby different defined operating position can be generated.
- control tube can be biased by elastic means both in the longitudinal axial direction and in the direction of rotation with respect to the guide sleeve, wherein the bias in the longitudinal axial direction, a displacement of the control sleeve within the housing forward, ie in the direction of the flow, and the bias in the direction of rotation Engaging (at least) one locking element in a corresponding undercut causes; the latter leads to a fixation of the relative position of the control tube to the guide sleeve.
- the locking element may be formed as a projection provided on the control tube, which can be screwed into a corresponding recess in the guide sleeve.
- control tube and the control or guide sleeve together form a pressure chamber whose size is defined by the relative position of the two components to each other.
- the outer surface of the guide tube and the inner surface of the control or guide sleeve with correspondingly arranged, annular edges form an annular pressure chamber which is filled by a pressurized fluid.
- the height of the pressure of the fluid can be varied as a function of the external pressure or of another counterforce, for example a spring force.
- the pressure chamber next to the ring shape may have any other shape.
- the pressure chamber can be formed only by a partial circle of the outer or the inner circumference of the guide tube or the control or guide sleeve.
- the size of the pressure chamber defines, via the position of the sleeve edges of the control sleeve, the mean position of the oscillating percussion piston in the housing. Displacement or lengthening / shortening of the control sleeve within the housing causes the center position of the percussion piston to also be displaced. As a result, the impact frequency of the percussion piston can be changed and at the same time the impact intensity can be influenced.
- the pressure chamber can be supplied with the pressure fluid via an additional line, which runs, for example, within the control tube. It may be compressed air, which is also preferably used as a drive medium for the percussion piston and is preferably guided by the control tube into the interior of the piston. Another embodiment may be the supply of a
- this liquid can be added at the same time be used in the area of the drill head or elsewhere in the soil to positively influence the drilling progress.
- drilling fluids can be used whose properties can be adapted to the respective drilling conditions by adding additives.
- the length and / or the position of the control or guide sleeve can be changed continuously in a certain adjustment range.
- a particularly good adaptation of the beat frequency / intensity to the given drilling ratios can be achieved.
- An alternative embodiment of a Rammbohrvorraum invention may have a control sleeve which is movably disposed within the percussion piston, and at least two control openings in the shell of the percussion piston, wherein the alternate positioning of the control openings in front of and behind the control sleeve, the ventilation of a between the housing and causes the impact piston located pressure chamber.
- the at least two control openings are offset in this embodiment in the longitudinal direction of the percussion piston to each other.
- Control openings in the longitudinal direction of the percussion piston can be achieved by a corresponding covering or releasing individual control openings different stroke paths of the percussion piston.
- the percussion piston is constructed in two parts, for example, with a further (partial) sleeve which is movably disposed within the (residual) percussion piston and by a defined rotation and / or translation within the (residual) percussion piston for a corresponding release or Covering one or more of the control openings ensures.
- the device according to the invention makes it possible to operate a ram boring device of the type described above in such a way that the frequency of the percussion piston movement and / or the impact intensity is changed via a displacement of the middle position of the percussion piston.
- both the frequency and the intensity of the impacts can be adapted to the given soil conditions. This can be carried out particularly advantageously during the drilling operation.
- the invention will be explained in more detail with reference to an embodiment shown in the drawings. 1 shows a sectional side view of a ram boring device according to the invention in a first embodiment
- Fig. 2 a detail view of the control sleeve of FIG. 1 including the adjacent
- FIG. 3 shows a section of a ram boring device according to the invention in a second embodiment
- FIG. 4 shows a sectional side view of a ram boring device according to the invention in a third embodiment
- FIG. 5 shows the control elements of a ram boring device according to the invention in a fourth embodiment.
- the embodiment of a ram boring machine according to the invention shown in FIG. 1 consists essentially of a housing 1 into which a drill head 2 is screwed.
- a percussion piston 3 reciprocates under the influence of compressed air in the housing 1, whereby the percussion piston 3 impinges on either a front impact surface 5 or a rear impact surface 6 within each period, depending on the position of a control sleeve 4.
- control sleeve 4 consists of two partial sleeves 7, 8.
- the partial sleeve 8 shown in the drawing on the right-hand side has a section with a reduced outer diameter, which essentially corresponds to the inner diameter of the left partial sleeve 7 equivalent.
- the sleeve 4 is connected via an intermediate element 9 with a control tube 10, which in turn for reversing the direction of movement of the ram boring device in the longitudinal axial direction within the housing displaceable and in two positions - one for the flow and one for the return of the device - can be fixed.
- the reversal takes place in exactly the same way as described in the introductory part of the description on the basis of the basis of the
- Impact piston finds a pressure equalization between the pressure chamber 12 and the Pressure chamber 14, which is formed by the outer surface of the percussion piston 3 and the inner surface of the housing 1, via the control openings 13 instead. Due to the larger effective area of the pressure chamber 14 compared to the pressure chamber 12, the resulting pressure force causes a rearward movement of the percussion piston third
- Pressure chamber 12 (forward) pressure force braking the percussion piston 3 and then accelerating in the opposite direction, i. towards the front to the drill head.
- the thus initiated forward stroke is terminated by the impact of the percussion piston 3 on the front striking surface 5.
- the control openings 13 have again the front (left) edge of the
- Control sleeve 4 is exceeded, so that a new cycle begins.
- the control bushing 4 consisting of the partial bushings 7 and 8, can be changed in length by an adjusting device (not shown), wherein the adjusting device brings about a pushing together and thus a shortening of the bushing 4 against a spring force of the spiral spring 16.
- the front part bush 7 is fixedly connected in the longitudinal axial direction with the control tube 10, so that a change in the bushing length causes no change in the position of the front control edge.
- the control openings 13 thus exceed the rear control edges of the socket 4 at different positions within the housing, ie the longer the control bushing 4, the later there is a reversal of the direction of movement of the control piston, so that this the rear reversal point to the front striking surface 5 must cover a longer path. This reduces the impact frequency of the piston.
- FIG. 3 an alternative embodiment of a length-adjustable control sleeve 104 is disclosed. This can be used instead of the control sleeve 4 shown in FIG. 2 in a ram boring apparatus according to FIG. 1.
- the control sleeve 104 of FIG. 3 also consists of a front partial sleeve 107 and a rear partial sleeve 108.
- the ram boring apparatus shown in FIG. 4 is based on changing the impact frequency and / or the impact intensity by shifting the relative position of the control sleeve within the housing 201.
- a small displacement of the control sleeve 204 defined in its length results in a change of the beat frequency and / or the impact intensity, while a larger displacement leads to a reversal of the direction of movement of the ram boring machine, since the percussion piston 203 no longer impacts on the front striking surface 205 impinges on the rear impact surface 206.
- a pressure medium line 218 is provided which is guided within the compressed air supply line 211 to the ram boring device and in this through the control tube 210 and further into the tip of the drill head
- a fitting 219 supplies an annular pressure chamber 217, which is formed by the outer surface of the control tube 210 and an inner surface of the control sleeve 204, with a fluid from the pressure medium line 218.
- FIG. 5 shows an embodiment of a ram boring device according to the invention, which differs substantially from the embodiments described above in that the control sleeve 304 is fixedly connected to the control tube 310 and a displacement of the entire control sleeve and thus the middle
- FIG. 5 only the control elements of the ram boring device are shown; these can be used, for example, with the other components (in particular
- the control tube 310 is slidably supported within a guide sleeve 320 fixedly connected via elastic connecting members 321 in a rear portion of the
- the control tube 310 forms three successive grooves 322, wherein depending on the longitudinal axial relative position of the control tube 310 to the guide sleeve 320 formed on the inside of the guide sleeve projection 323 can engage in one of the grooves 322.
- this has a cross-section which allows the projection 323 to engage the guide sleeve 320 in the grooves 322 at a certain rotational relative position of the control tube 310 (locking position), whereby a longitudinal axial relative displacement is prevented, and at least a second rotational relative position (switching position), which is preferably offset by 90 ° to the first, no engagement of the projection 323 is provided in one of the grooves 322, and therefore a longitudinal axial relative displacement is possible.
- Corresponding cross sections of the control tube 310 and the corresponding guide sleeve 320 are disclosed in DE 39 09 567 A1, in particular in FIGS.
- control tube 310 Via a spring 324, which is defined between the guide sleeve 320 and the front end of the control tube 310, the control tube 310 is biased relative to the guide sleeve 320 both in the longitudinal axial direction and in the direction of rotation; in such a way that the control tube 310 is moved relative to the guide sleeve 320 to the front (in Fig. 5 to the left) and at the same time in the locking position.
- control tube can be rotated from the locking position to the switching position. If the pressure chamber formed by the control tube 310 and the percussion piston then with a high
- control tube 310 is fixed in its foremost position; this corresponds to an engagement of the projection 323 in the rear of the grooves 322. In this position, the control tube 310 and thus also the control sleeve is positioned as close as possible to the front striking surface of the housing. This causes a short stroke of the percussion piston with a relatively small intensity but high beat frequency.
- the ram boring device If the projection 323 engages in the middle of the grooves 322, the ram boring device is still in its forward position, the percussion piston but by a displacement of the control sleeve and thus the middle position of the percussion piston to the rear at each stroke cycle exerts a longer stroke with higher intensity; At the same time, a lower beat frequency is achieved.
- the center position of the percussion piston Upon engagement of the projection 323 in the front groove 322, the center position of the percussion piston is offset so far back that the percussion piston no longer impinges on the front impact surface of the ram boring device, but on the rear, whereby a reversal of the direction of movement of the ram boring device can be achieved can.
- the grooves 322 (in particular, the two front grooves) may be (rotationally) staggered with respect to each other, which can be made to switch gradually between the individual switching positions. This can be prevented that, instead of switching between the two switch positions for the lead, unintentionally switched directly from, for example, the rear groove in the front groove, whereby the direction of movement of the ram boring would be reversed.
