Definitions

  • the present invention relates to descaling apparatus for descaling and cleaning canalization installations such as industrial pipes, sewers, conduits and the like. More in particular, the invention concerns propulsion means for descaling apparatus incorporating components adapted to generate water hammer blows.
  • cutters disposed radially to score or scrape the incrustations.
  • these cutters end with two V-shaped blades to remove the notched incrustations, to smash and detach it from the internal wall of the canalization.
  • Scrapers and some shaft centering tools are pulled elastically against the internal wall of the conduit, and a propulsion unit pushes the apparatus forward by the fluid pressure.
  • the propulsion unit may be a rotating one.
  • such a unit comprises a tapered frustum cup mounted on the shaft, the largest edge of which rests on the internal wall of the canalization, so that the fluid pressure pushing against the interior hollowed surface of the cup creates the thrust required to move the descaling apparatus forward.
  • the internal section of the pipe is completely obstructed by the propulsion device itself, only some orifices are provided to let a part of the fluid pass forward in order to expel the incrustations in front of the apparatus.
  • the propulsion devices known from the prior art are operated only by the fluid pressure, and they function simply as a piston, using only the static pressure.
  • the propulsion unit in accordance with the invention utilizes, besides the simple fluid pressure, the dynamic pressure created by repeated water hammer strokes, which increases the power of the propulsion device enormously and thereby the eflicacy of the apparatus to smash the incrustations.
  • the propulsion unit according to the invention is distinguished by two propulsion devices of the same construction connected to a central carrying shaft, between which there is a centering device for the propulsion unit in the pipe.
  • Each propulsion device comprises a set of elastic sections fixed angularly equidistant to the back of a plate perpendicular to the central shaft. These sections are inclined backwards and loaded with a heavy slab. The outward edges of the section-s rest against the inner surface of the pipe. A space is left between one section and the following one permitting the flow of water.
  • the elements are arranged in a manner that, automatically and alternatively, under the pushing action of the water, both sections of the propulsion devices are held against their carrying plate. Each momentary stop of the sections creates a water hammer effect which considerably increases the pushing'force of the propulsion unit.
  • FIG. 1 shows a longitudinal sectional view of the propulsion unit taken along line II of FIG. 2,
  • FIG. 2 shows a sectional end view of the propulsion unit taken along line IIII of FIG. 1,
  • FIG. 3 shows, to an enlarged scale, one element of one 3,26ZJ43 Patented July 26, 1366 of the propulsion devices seen in the direction of the arrow in FIG. 1,
  • FIG. 4 shows a sectional View taken along line IV-IV in FIG. 3,
  • FIG. 5 shows a front view of one of the centering arms of the propulsion unit
  • FIG. 6 shows the same centering arm in side view.
  • the propulsion unit 1 is the central shaft on which are mounted all the elements of the propulsion unit.
  • This propulsion unit comprises three parts, an anterior propulsion device 3, a posterior propulsion device 5 and a centering device 7, 8 placed between the two propulsion devices.
  • the shaft 1 has at its ends toggle loops 2 in order to be connected with the descaling devices which are ahead of it and at its rear. These devices are described in detail in Swiss Patent No. 367,361 of the applicant.
  • First the centering device is described which is placed between the propulsion devices 3 and 5.
  • This device comprises two similar parts each having asocket 9 or 10 provided with a setting collar 12 or .18, and having each six radial hinge knuckles 13 or 19, placed at angles of 60 relative to one another.
  • the hinge knuckles 13 are displaced by a 30 angle with respect to the hinge knuckles 19.
  • other hinge connections 14- are provided, similarly the sockets 20 are pivotally connected to knuckles 19.
  • the flexible arms 15 and 21 are connected to members 14 and 20, respectively.
  • Each flexible arm 15 and 21 carries at its outward end a roller 16 or 22, which rests against the internal surface of the pipe 17 which is to be cleaned.
  • the roller carrying arms of both devices being identical, an arm of the anterior centering device 7 is now described with refer once to FIGS. 5 and 6.
  • the drawings show the hinge knuckle 13 which supports by means of a pin 28 the hinge knuckle 14 which has a slot 29 in which one end of a flexible steel blade is received acting as a flexible arm 15.
  • the hinge knuckle and the flexible blades are fixed together by means of two screws 30 extending therethrough.
  • the blades are provided with oval holes so that the arm 15 may move a few degrees in its plane, in case some'transversal forces are encountered during the propulsion action.
  • the other ends of the steel blades are secured in a similar manner by means of screw 34 in the slot 33 provided between the jaws of a frame 32. Also here the holes on the blades are of oval shape.
  • the frame 32 is provided with a three-thonged fork 31 carrying the roller 16 by means of a pin 35 passing through these branches.
  • the roller 16 comprises two sets of discs 36, each set having several adjacent discs of different diameter, decreasing from the center to the extremity of the roller.
  • the outline of the roller is an are having a radius corresponding to that of the pipe 17.
  • the edges of these discs are provided with zig-zag ribs.
  • the six arms 15 are displaced by an angle of 30 relative to the six arms 21, although they have been represented as being in the same plane in FIG. 1, in order to simplify the drawing.
  • Sockets 9 and 10 carrying arms 15 and 21 are placed adjacent to one another on the central shaft 1 and they can only turn together on the shaft, as
  • a device for simultaneously setting both parts of the centering device.
  • hexagonal plates 24, 23 engage the sockets 9 and 10, respectively, which plates are connected together by means of three rods 25 which in order to receive the screw 26 which fixes it to the plate 24.
  • the propulsion devices 3 and are identical except for one detail. Only the forward propulsion device 3 is described.
  • the propulsion device 3 comprises a socket 37 in engagement with the shaft 1 and secured thereto against rotation by means of a key 4.
  • the socket of the rearward device 5 is retained in the same manner by a key 6 disposed at an angle of 30 relative to the key 4.
  • the socket 37 is connected with a support plate 38, which may be of circular shape, extending perpendicular to the axis of the socket and provided, at its front end, with twelve reinforcing radial ribs 39.
  • a calotte or cap 40 is welded to the sleeve and to the edge of the plate 38, with the ribs 39 resting against the internal surface of the cap.
  • there are twelve radial compartments each provided with a water inlet 43 in the plate 38 and an outlet 41 on the cap 40.
  • a nozzle 42 is threadedly received which injects the water toward the inner surface of the pipe 17.
  • the rearward propulsion device 5 is not provided with nozzles.
  • Both the stiffening plates 49 and 4911 are shorter than the leather discs; the length of plate 49 is almost twothirds of the circular leather sectors while the length of the plate 49a is nearly six-tenths of the sector 48. As for this difference in length, the bolts 51 of the exterior row pass through the three leather discs and the two steel plates, while the bolts 52 of the inner row pass only through the leather discs and the larger steel plate 49.
  • Disc 49a is intentionally shorter to avoid a breaking of the leather disc adjacent to the load plate 50.
  • the center portion is cut and is fixed between a ring 45 coaxial with the socket 37 and the plate 38.
  • the plate has six threaded bolts 44 alternating with six pins 47 to which the sectors or sections 56 and the rings 45 are secured.
  • Each bolt receives a tightening nut 46 which enters a corresponding aperture of the ring 45 leaving a certain amount of play.
  • the pins 47 enter with slight friction into corresponding holes of the ring 45 in order to make the ring stable relative to the plate 38, which is an essential condition so that the sector or section 56 will be firmly supported.
  • the disc 48 could be made of synthetic material, such as nylon, possibly reinforced with steel wires to increase the flexibility.
  • the sectors 56 when mounted on the plate 38 present edges defining a circumference of a diameter slightly larger than that of pipe 17. Consequently, when the propulsion unit is introduced in the pipe, all the sectors are rearwardly inclined.
  • the space 4 53 left between the adjacent sectors 56 is slightly V- shaped.
  • Both the propulsion devices 3 and 5 are angularly displaced relative to one another and axially immovable with respect to each other.
  • the sockets 9 and 10 carrying the centering arms 15 .and 21 are, in turn, mounted rotatably on shaft 1.
  • lubricant is introduced between sockets 9 and 10 and shaft 1 by means of a grease-cup threadedly mounted in the holes 36a provided in the sockets 9 and 10 and in a sleeve of a tie-beam 36 placed between socket 10 and the socket of rearward propulsion device 5.
  • the sectors 56 of the forward propulsion device are more flexible than the sectors of the rearward propulsion device.
  • the leather discs 48 of the forward device 3 may be thinner or of more flexible material, or the plates 49, 49a may be of different material than those of the rearward device 5.
