Definitions

  • the invention relates to a cleaning device for channels or pipes with a water connection for a water hose housing, which has on the side of the water connection for generating a feed movement by recoil force rear water outlets, which are connected to the water connection, and which on its front side with one of the supplied water is provided by means of a water motor which can be driven by a milling spindle.
  • Cleaning devices of the above type are used in practice to clean heavily soiled channels or pipes. With such devices, a milling cutter inserted into the milling spindle is able to remove even very firm deposits within the pipes or channels.
  • the supplied water flows into the milling spindle and exits from it via tangential outlet openings.
  • the milling spindle therefore rotates according to the same principle as conventional lawn sprinklers due to the recoil forces of the escaping water.
  • the water supplied has a working pressure of 120 to 200 bar and usually contains impurities. These are inevitably absorbed because the water flowing back into the sewer when working in the sewer is sucked in and fed back to the cleaning device for water supply.
  • the high pressure and the high proportion of impurities in the water supplied mean that the relatively complicated water flow in the cleaning devices leads to relatively rapid wear.
  • Another disadvantage of the known cleaning devices is that that despite the high water pressure, the torque available on the milling spindle is often not sufficiently high.
  • the invention is based on the problem of designing a cleaning device of the type mentioned at the outset in such a way that its milling spindle can rotate with a sufficiently high torque and the wear in the cleaning device is as low as possible as a result of contamination in the water supplied.
  • the water motor has a turbine wheel arranged near the rear of the housing and in that between the turbine wheel and the milling spindle there is arranged a transmission which is sealed off from the water supply and connects the turbine wheel with the milling spindle and reduces the speed of the turbine wheel to a slow reduction is.
  • the torque increases significantly due to the transmission between the turbine wheel and the milling spindle. Thanks to the design according to the invention, the torque can easily be increased 100-fold. Since the turbine wheel is arranged near the water connection and the transmission is sealed off from the supplied water, only the turbine wheel and areas immediately adjacent to it are exposed to the water, so that this area can be designed to be highly wear-resistant at a relatively low cost.
  • the cleaning device is designed to be particularly simple in terms of construction if, according to an advantageous development of the invention, the turbine wheel is arranged on an input shaft carrying a pinion within the gearbox, in alignment with the input shaft in the gearbox Intermediate shaft and an output shaft is arranged, to which two mutually aligned auxiliary shafts are provided, and that the torque transmission from the input shaft to the intermediate shaft and then from the intermediate shaft to the output shaft in each case for translation into slow motion by gearwheels and pinions on the input shaft, the intermediate shaft and the output shaft and the two auxiliary waves.
  • the gearbox is particularly compact and enables a large reduction ratio if the auxiliary shafts each have a diameter-sized gear and a pinion from the water connection, the gear with a pinion of the input shaft and the intermediate shaft and the pinion with a gear of the intermediate shaft or comb the output shaft.
  • a further increase in the reduction ratio can be achieved with a slight increase in the external dimensions and without an increase in the cross section of the cleaning device, if the output shaft engages with an internal sprocket of a drive sleeve connected to the milling spindle.
  • the cleaning device has a particularly small cross-section, so that it can also be used well in narrow pipes and ducts if, according to another development of the invention, the milling spindle is arranged coaxially in a cylindrical housing of the cleaning device and the input shaft with the turbine wheel, the intermediate shaft and the output shaft run axially parallel to the milling spindle and thus eccentrically in the housing.
  • the invention permits numerous embodiments. To further clarify its basic principle, one of them is shown in longitudinal section in the drawing and is described below.
  • the drawing shows a cylindrical housing 1, a milling spindle 3 rotatably mounted in the housing 1 protrudes from the front side 2 thereof.
  • the housing 1 On its opposite rear side 4, the housing 1 has a water connection 5, to which a water hose (not shown) can be connected for supplying water under high pressure.
  • the water supplied partly flows backwards via rearward-facing water outlets 6, as a result of which the housing 1 has the tendency to move forward as a result of the recoil forces which occur as a result.
  • a portion of the water supplied passes through bores 7, 8 into a turbine chamber 9 and hits a turbine wheel 10 there with a sharply focused beam, which is mounted on an input shaft 11 of a transmission 12 arranged eccentrically in the housing 1.
  • a seal 13 prevents water from the turbine chamber 9 from getting into this transmission 12.
  • the input shaft 11 has a first pinion 14 in the interior of the transmission 12, which drives a first gear 15, which is arranged on a secondary shaft 16 mounted parallel to the input shaft 11 and is connected in a rotationally fixed manner to a second pinion 17.
  • This second pinion 17 meshes with a second gear 18 which drives an intermediate shaft 19 arranged in alignment with the input shaft.
  • the intermediate shaft 19 drives a third gear 21 of a second auxiliary shaft 22 in exactly the same way as the input shaft 11 via a third pinion 20 and is connected to a fourth pinion 23 which meshes with a fourth gear 24 of an output shaft 25.
  • the output shaft 25 has at its milling spindle end a pinion 26 which engages in an internal toothing 27 of a drive sleeve 28 and thereby drives it with a further reduction in speed.
  • the torque is transmitted from this drive sleeve 28 to the milling spindle 3 via a slip clutch 29.
