Definitions

  • the invention relates to a carriage for a channel cleaning device to be centrally guided in a channel with a central support and at least three scissors distributed around the circumference of the support, each consisting of a first scissor arm and a second scissor arm, the inner ends of each first scissor arm pivotally a first sleeve are held, which is displaceable in the longitudinal direction of the carrier.
  • Such a carriage is in the FR 1 308 927 A described.
  • three parallel to the support extending threaded rods are guided, on each of which an adjusting nut resting on the sleeve is screwed.
  • the setting angle of the scissor arms can be changed.
  • the second scissor arms are pivotally held directly on the carrier.
  • a sewer cleaning device with a central support and several parallel extending support beams described with the central Carrier connected via a parallelogram linkage. There are rollers and scratches on the outside of the stringers.
  • an adjusting lever is provided for each support beam, which is connected in each case with its outer end on the associated support beam and with its inner end to a spindle integrated in the central support in each case pivotally.
  • a lever of the parallelogram linkage and an adjustment lever each form a triangle, so no scissors with an open outward-facing angle. This and the continuous stringers prevent the unit from being able to pass through strongly curved channel sections.
  • the object is to be able to perform an adjustment of the diameter of the carriage in a simple manner.
  • the adjusting means should be designed so that there are no changes during operation, since the sewer cleaning device should always remain centrally located in the channel.
  • the carriage should be designed so that even highly curved channel sections can be passed.
  • each second scissor arm is pivotally supported on a second sleeve, wherein the first sleeve relative to the second sleeve is displaceable, that the first sleeve has an internal thread, with which it is connected to an external thread on Carrier is screwed, and that the second sleeve is rotatably supported on the carrier and is located with a front side on a flange on the carrier.
  • the adjustment can be made relatively easily.
  • the first sleeve needs only to be rotated relative to the carrier, which is low Power is possible because the scissor arms provide a large lever. Furthermore, no separate tool is needed to make the adjustment.
  • the threaded connection between the first sleeve and the carrier is self-locking, thereby also vibrations during operation do not lead to an adjustment.
  • the sleeve remains in its position and the once set cross-section of the carriage is maintained even during operation.
  • Such a backup of the first sleeve can also be achieved or supported with a locking screw with lock nut.
  • rollers are mounted on the outer ends of the first and second scissor arms, which can be applied to the channel walls, wherein in each case a first scissor arm and a second scissor arm are connected in their central region via an axis, so that the outer Scherenarmabitese form an open angle to the outside. Due to the direct connection of the rollers with the arms can be dispensed with a longitudinal web, as he still in the DE 20 2010 012 468 U1 is described. Such a longitudinal web also has the disadvantage that the carriage must first be pulled completely out of a channel into a revision shaft, so that it can be hoisted up from there.
  • the slide can in fact cross position without colliding with the ceiling of the channel. Since the scissor arms in contrast to the sewer cleaning device of US 1,631,562 form a pair of scissors with an open outwardly facing angle, can also be traversed strongly curved channel sections, because the curved channel wall can dip into the open angle.
  • the rollers are held by a bearing on the scissor arms. These bearings are encapsulated to prevent contamination and thereby maintain smoothness.
  • Such a slide should be used in particular with a sewer cleaning device, which consists of a nozzle head with a central hose connection. This nozzle head can be easily screwed onto the carrier.
  • the nozzle body consists of a base body and a nozzle body screwed thereon.
  • the entire nozzle body carrying nozzle is replaced while the body remains on the carrier.
  • the carrier may be made hollow, so that water, which is conducted by means of a hose to the nozzle head, is passed through the carrier to its front side facing away from the nozzle head, there may be receiving means for another nozzle head, which is connected to the water through the carrier has flowed, is supplied.
  • Recording means on the carrier can also be provided for a camera. If a camera is mounted, the cables leading to it are guided through the hollow support to the front end of the support.
  • FIGS. 1 and 3 It should be noted that the side view along a bent line and thus the lower pair of scissors is not shown in an oblique view, but in a straight plan view.
  • the carriage consists of a carrier 1, which consists of a cylindrical tube 2.
  • a carrier 1 which consists of a cylindrical tube 2.
  • an adapter 3 is provided for screwing a nozzle head described in more detail below.
  • the adapter 3 has a slightly larger diameter than the tube 2, so that a flange opposite the tube cross-section is formed.
  • a tube extension 4 is inserted, whose outer diameter corresponds to the outer diameter of the tube, so that there is a flush transition to the tube 2.
  • the tube extension 4 has an external thread 5.
  • On the tube 2 or on the tube extension 4 are a first sleeve 6 and a second sleeve 7.
  • the second sleeve 7 abuts against the flange formed by the adapter 3 and is connected via a retaining ring 8, which is fastened by means of a grub screw 9 on the tube 2, held in this position.
  • the fuse but is not so strong as that the second sleeve 7 could not rotate relative to the tube 2.
  • the first sleeve 6 has an internal thread 10, with which it is screwed onto the pipe extension 4.
  • first scissor arms 12 and second scissor arms 13 are pivotably articulated about an axis.
  • the scissor arms 12, 13 each consist of two parallel leaves.
  • rollers 14 At the outer ends of the first and second scissor arms 12, 13 are rollers 14, wherein the bearings are encapsulated to prevent contamination.
  • a first scissor arm 12 and a second scissor arm 13 are connected to each other with their central region via an axis 15.
  • the first sleeve 6 screws back and forth.
  • the scissor arms 12, 13 either approximately at an angle of 90 °, as in Fig. 1 shown, or lie flat on each other, as in Fig. 3 shown.
  • the carriage has a large diameter, so that it can be used in a channel 16 with a large cross-section, see Fig. 2 , or in a channel with a small cross-section, which is not shown here.
  • the rollers 14 come to rest against the channel wall, so that the carrier 1 and thus an attached nozzle head is centrally aligned in the channel.
  • a nozzle head In the Fig. 4 such a nozzle head is shown.
  • This consists of a main body 21 and a nozzle body 22.
  • a hose connection 23 At the rearward side of the nozzle body is centrally located a hose connection 23, therefore nozzles 24 are arranged.
  • the water entering the hose connection 23 is deflected and directed into the nozzles, which direct the water in a jet to the rear and obliquely outward.
  • the outgoing jet drives the carriage and, on the other hand, cleans the canal walls. So that this is not hindered by the carriage, the nozzle head is still behind the carriage. The rear rollers are seen in the drive direction even before the nozzle head 20th
  • the nozzle body 22 is unscrewed from the main body 21 and replaced by a nozzle body with other nozzles.
  • the nozzle body 22 has a central bore which leads from the washing chamber 25 into the hollow carrier 1 and carries the water from the hose connection 23 to the front side of the carrier. There, another nozzle head can be used to achieve a pre-cleaning of the channel.
  • a camera can be used to make the channel inner wall visible on a monitor.
  • the interior of the tube 2 can be used as a guide for a cable to the camera.
  • the tube 2 is closed by means of a plug and thus kept free of water.
  • the Fig. 4 further shows the sewer cleaning device together with a so-called hose deflection 26, the can be removed automatically by means of a telescope 27 of the shaft wall of a inspection shaft 28 while the slide at least for the most part pulls out of the channel 16.
  • the rollers 14 are located directly at the outer ends of the scissor arms 12, 13 - the slide can also be pulled up into the inspection shaft 28, if it has not been completely pulled out of the channel 16, as in of the Fig. 4 is shown. Rather, the carriage can still be inclined in the channel 16 and obliquely threaded out of the channel 16, wherein the edge 29 between the inspection shaft 28 and the channel 16 in the scarf arms 12, 13 formed by the open angle 30 dips.
