Definitions

  • the invention relates to a device for locating ram boring machines, such as are used for trenchless laying of underground lines or for the destructive replacement of underground lines.
  • ram boring machines and earth displacement hammers or earth rockets move automatically under the influence of a pneumatically or hydraulically driven percussion piston through the ground and are connected via a line to an above-ground pressure medium source.
  • a particular problem with such devices is the determination of the respective position in the ground in order to be able to intervene in a controlling manner or to dig out a device stuck in the ground. This is usually done with the help of a transmitter / receiver system, which however makes it necessary to arrange either the transmitter or the receiver in or on the ram boring machine.
  • This known locating device has the disadvantage that the maintenance or replacement of a defective locating device is difficult due to the positioning within the ram boring machine. This is particularly serious since the locating device is particularly stressed by the impact forces occurring in the ram boring machine and this particular stress increases the susceptibility of the locating device. When installing or replacing the locating device, the ram boring machine must first be dismantled.
  • German utility model 88 04 347 proposes a device with a radio transmitter for locating ram boring machines.
  • This has a cylindrical housing which is connected by an end fitting to a compressed air line and by a second end fitting to the ram boring machine.
  • the radio transmitter is located inside the housing in the flow path of the compressed air and the compressed air flows around it.
  • the housing of the locating device is therefore an integrated part of the compressed air line, but is designed in such a way that it is a Can record stations. This requires a pressure-proof probe housing.
  • the compressed air hose When using the locating device, the compressed air hose must be detached from the ram boring machine, then connected to the locating device and connected to the ram boring machine.
  • the position of the locating device and thus of the ram boring machine can be determined by radio from the surface of the earth with the aid of a receiver.
  • the housing of the locating device In contrast to the compressed air line, the housing of the locating device represents a rigid body. If the locating device is now between the ram boring machine and the compressed air line, the rigid ram boring machine is extended by a corresponding amount. This leads to a reduction in the maneuverability of the ram boring machine and requires a correspondingly enlarged construction or starting pit.
  • the locating device cannot be used for any hose or ram boring machine.
  • a predetermined breaking point is created at the connection point between the ram boring machine and the locating device, which is particularly stressed by the greater leverage effect.
  • the flow path of the compressed air with narrow cross sections causes the occurrence of disadvantageous turbulence.
  • the invention is therefore based on the problem of creating a locating device which enables a simple connection of the radio transmitter to the ram boring machine, preferably without loosening the connection between the compressed air line and the ram boring machine, and does not hinder the hammer drill in its maneuverability, and is less susceptible to mechanical influences during drilling owns and can be easily dismantled.
  • the solution to the problem is based on the idea of not integrating the radio transmitter into the compressed air line or the ram drilling device, as in the case of known locating devices, but rather to position it outside in a simple manner.
  • the invention realizes this idea by a housing for the radio transmitter or also the receiver with a fastening which makes it possible to connect the housing to the media line.
  • the housing preferably encompasses the media line by means of two housing parts, one of which accommodates the radio transmitter or receiver.
  • the housing part receiving the radio transmitter then has a recess for the radio transmitter and at least two connection points for the second housing part.
  • the housing can be flattened in the front or in the rear area so as not to hinder the movement of the ram boring machine and to keep the stress on the housing from the earth low.
  • the housing according to the invention enables the use of any radio transmitter or receiver even without adapting the recess in the housing of the locating device if it is only large enough.
  • an existing radio transmitter can be used with any ram boring machine regardless of the hose or hose coupling size. It can be installed anywhere, directly behind or at any distance from the ram boring machine. Due to the simple and compact design of the housing, the use of plastic as the housing material is possible. In contrast to known locating devices, no pressure-resistant housing is required in the piggyback transmitter according to the invention. This leads to a significant reduction in manufacturing costs.
  • the piggyback transmitter does not affect the media line in any way, thus avoiding both a narrowing of pressure line cross sections and the development of turbulence.
  • the housing 1 consists of a part 2 receiving the radio transmitter and a complementary part 3.
  • the housing parts have a central bore 4 which encloses one or more fluid lines 5 leading to a ram boring device, not shown.
  • the transmitter-carrying housing part 2 has a recess 6, in which a radio transmitter 7 is inserted.
  • Both housing parts 2, 3 have bores 9, 8 into which bolts 10 and 11 are used for locking.
  • both housings At the front and rear ends, both housings have flats 12 and 13, which complement each other to some extent. These flats prevent the housing from getting stuck on stones, roots or other solid objects during tunneling.
  • each ram boring machine can be easily equipped with a location system without the compressed air supply being impaired.
  • the housing costs are minimal and, for a wide range of ram boring machines, only a few housings and transmitter required, while in case of fixed systems each ram boring machine requires its own receiver or transmitter.
