Definitions

  • the invention relates to a housing for receiving a transmitter for determining the position of an underground ram boring machine.
  • Such housings are known in various embodiments and serve a transmitter in the area of a ram boring machine or To fix the drill head, with the help of the transmitter the course of an underground Track the hole and the position of the ram boring machine and the drilling direction to be able to correct or cancel.
  • the transmitter is in the drilling machine housing integrated so that the transmitter housing is part of the ram boring machine is.
  • Such constructions have the disadvantage that they can be replaced a defective transmitter or to replace the battery first Drill housing must be opened.
  • Another disadvantage is in that the impact forces occurring in a ram at Transmitter arranged transmitter immediately transferred to the transmitter become.
  • One such device is in PCT laid-open specification 87/03924 described.
  • transmitter housings are independent of the ram boring machine known, such as in the German utility model 88 04 347 described as a fitting between compressed air line and ram boring machine be used. There are flow paths within the adapter arranged for the compressed air supply to the ram boring machine so that this Flow around the transmitter. Such a device does not only require one pressure-resistant transmitter housing, but also a considerable design effort. Such a transmitter is usually behind the ram boring machine, arranged for ram boring machine lengths from 0.8 m to 2 m.
  • the ram boring machine disassembled to couple the transmitter housing described the drill head is removed and special lanyards for the Transmitter housing can be used. Only then can the described Transmitter housing are placed on the ram boring machine.
  • the invention is therefore based on the object of a transmitter housing create the difficulties of placing a transmitter in the front Avoid area of a ram boring machine.
  • the housing according to the invention is particularly suitable for use with Standard ram boring machines.
  • the housing For connecting the transmitter to the ram boring machine the housing must only on the displacement head of the The ram boring machine is attached and fixed with the connecting means.
  • the housing with dowel pins on the displacement head fixed which enables easy removal and removal of the housing. This offers the advantage that the transmitter and battery can be replaced without any problems can be and on the other hand a single transmitter for several Pile rammers can be available.
  • connection and detachment of the housing with the ram boring machine is like this simply that the user only needs one transmitter for a variety of Drill rams of different designs and dimensions needed and a change on site is also possible. After The transmitter will help decide on the ram boring machine to be used The housing is removed from the previously used device and onto the selected one Device plugged in.
  • the housing according to the invention is already suitable for retrofitting Trade of drilling equipment, in particular ram drilling equipment.
  • the transmitter in the housing can be used as a probe to detect the lateral position, the depth position, the position in the axial direction and, if necessary be suitable for the slope and roll of the ram boring machine.
  • the transmitter is preferably arranged in the foremost tip of the housing, to enable a particularly exact location determination. This is important for use in inner-city areas because of an inexact Drill guide to destroy existing and in this area numerous supply lines can lead.
  • the transmitter is equipped as a radio transmitter in damping elements against vibrations and axial and radial impacts embedded.
  • torsion dampers can be provided be.
  • the dampers can be designed and arranged on the transmitter be that they also absorb axial tensile forces.
  • the housing preferably has slot-like openings in the region of the Transmitter to increase the transmission power and to shield the transmitter signals to avoid.
  • the openings can be made with a non-conductive Plastic mass sealed or the transmitter in a plastic inner tube be arranged to prevent the ingress of dirt.
  • the housing for the transmitter receptacle 1 consists of a housing tip 2 with a recording room 3 for a transmitter 4.
  • the transmitter 4 is in the recording room embedded in damping elements 5,6. They can do this be designed that starting from an acceleration of the transmitter Tensile forces, for example, by a positive connection between Damper and transmitter are picked up by the damper.
  • the top of the case 2 has slot-like transmission openings 7 on its peripheral surface Facilitate the exit of the transmission signals of the transmitter 4 from the recording room 3 of the housing tip 2.
  • the housing tip 2 is designed as a drill head tip and in front of the main displacement head 8 of the housing 1 arranged.
  • the housing 1 is in its outer shape is designed as a stepped head.
  • the housing has 1 connecting means in its rear region 9, 10, 11, 12 including a receiving recess 13 for the head 14 a ram boring machine 15.
  • the receiving recess 13 is corresponding to the usual step head or with a conical head 17 (FIG. 5) educated.
  • the cone 17 can have an incline, which a self-locking connection between the transmitter housing 1 and Drill head 14 allows.
  • the housing is used to plug the housing 1 onto the ram boring machine 15 with the receiving recess 13 on the step head 14 of the Ram ram pushed on and with fastening bolts 9,10,11,12 the drill head 14 fixed.
  • the transmitter housing is removed in an equally simple manner by loosening the fastening bolts 9, 10, 11, 12 and removing the transmitter housing from the drill head 14 of the Ram drilling machine 15.
  • the transmitter housing can be equipped with a movable displacement head steerable ram boring machine (Fig. 1,2) as well as with a rigid head one Standard ram boring machine (Fig. 3) are operated.
  • the arranged in the housing tip 2 transmitter 4 must be due to the existing slot-like transmission openings 7 against the ingress of Dirt are protected. This can be done with the help of a surrounding the transmitter 4 Plastic sleeve 16 (Fig. 4) or by filling in the slot-like Openings are made with a non-shielding plastic compound.
