Definitions

  • the invention relates to a pipe cleaning machine for driving cleaning spirals of different diameters, with a housing, a motor-driven hollow shaft with an inner diameter for the passage of the cleaning spiral, with a rotary clutch for taking the cleaning spiral, consisting of a set of clutch shoes that can be driven by the hollow shaft and can be moved into the projection of the inner diameter against the cleaning spiral, with a container serving to hold the end of the cleaning spiral which is not in use, which can be aligned with the housing via a connecting coupling with the rotating coupling, and with one into the rotating coupling from the outside insertable rotatable collet that bridges diameter differences by means of jaws or fingers.
  • Such pipe cleaning machines are used to clean all possible sewage pipes and channels, which are often of considerable length and are provided with a large number of elbows, elbows, etc. It happens that the place of access to the pipeline is a considerable distance from the blockage point.
  • the cleaning spirals which are not "real" spirals in the mathematical sense, but in principle coil springs, are therefore manufactured in finite partial lengths and can be extended using special couplings.
  • the pipe cleaning machines for driving these cleaning spirals are usually designed in the form of suitcases or small trolleys, from which the end of the cleaning spiral which is not in use emerges at the rear. In the past, this end was rotated freely on the floor, often moving in a circle and starting to hit.
  • the known drums are therefore equipped with a brake, usually a conical brake, which is actuated via a mechanism present in the machine housing, usually the clutch lever actuated in the opposite direction.
  • the most common nominal diameters of the cleaning spirals today are 8, 10, 16 and 22 mm. Different spiral diameters are required to meet the different cleaning requirements, which are mainly determined by the dimensioning and the course of the pipeline. Because of the large volume of cleaning spirals of large diameter wound in drums, it is not possible for practical reasons to provide, for example, a single drum for all four nominal diameters, the volume of which would then of course have to correspond to the cleaning spiral with the greatest length and the largest diameter. As a rule, the procedure is to use drums of different diameters.
  • the decisive value of a pipe cleaning machine is the inner diameter of the hollow shaft, which must be slightly larger than the outer diameter (nominal diameter) of the largest cleaning spiral used.
  • the collets are triple-slotted tubes that are firmly connected to the drum and its brake cone.
  • the outer diameter corresponds to the 16 mm spiral
  • the inner diameter corresponds on the one hand to the 8 mm spiral and on the other hand to the 10 mm spiral.
  • two collets and two drums are required, which also have the above-mentioned shortcomings.
  • a so-called guide hose is added to the known machine. This solution requires extensive accessories, which must be carried along with the machine at all times.
  • the invention is therefore based on the object of specifying a pipe cleaning machine of the type described at the outset which manages with a minimum of accessories with regard to the containers for accommodating the cleaning spirals and with regard to the means for adapting to different spiral diameters.
  • the object is achieved in that the container for the cleaning spiral is designed in a known manner as a guide hose, that the inside diameter of the guide hose and the connecting coupling are equal to or larger than the inside diameter of the hollow shaft and that the collet for the adaptation of the rotary coupling and the guide hose with connection coupling to different spiral diameters is detachably mounted in the connection coupling.
  • releasable is to be understood to mean any type of mounting or fastening which prevents unintentional displacement of the collet within the hollow shaft or the rotary coupling, but which allows the collet to be replaced without special tools or even exclusively by using force.
  • This can happen, for example, in that the collet is held in the connection coupling in a form-fitting manner by means of a screw that can be tightened against the collet bearing.
  • a screwdriver is sufficient to remove the collet with its bearing from the connection coupling.
  • Such locking connections are known as ball locks.
  • a steel ball which can be displaced to a limited extent under the action of a spring, is pressed into a corresponding recess in the collet bearing. This effectively prevents undesired entrainment of the collet bearing; however, the collet can be removed from the connection coupling together with the bearing by a pulling force.
  • the inside diameter of the hollow shaft is the decisive size for the respective pipe cleaning machine.
  • the measure of making both the inside diameter of the guide hose and that of the connecting coupling equal or larger than the inside diameter of the hollow shaft means that the guide hose can be used for all cleaning spirals for which the machine (without the use of the collet) is also designed is. It is therefore sufficient to add a single guide hose for each machine type.
  • the easy release of the collet from the connection coupling means that the guide hose can be used both with and without a collet.
  • both the rotary coupling and the collet are designed to be compressible in the unloaded state to at least two different nominal diameters of cleaning spirals due to the distances between the coupling jaws and the jaws.
  • a housing 1 which encloses all functional parts of the pipe cleaning machine and has approximately the shape of a suitcase in outline.
  • a carrying handle 2 is provided for transport purposes; for parking two pairs of rubber feet 3 and 4 are used, of which the right pair 3 is fastened to a bracket 5 with elongated holes, not shown, in order, for example, to be able to compensate for the inclination of the machine on an inclined installation surface.
  • Both hollow shafts consist of a hollow cylindrical part and a respective hollow cone 10 or 11, the hollow cones with their largest cross-sectional areas facing each other. Hollow shafts and hollow cones have identical axes of rotation.
  • the hollow shaft 8 carries a toothed belt pulley 12, which has a toothed belt 13 is connected to a toothed belt pulley 14 which is seated on a drive shaft 15 of an electric motor 16 which can be switched with respect to its direction of rotation.
  • the hollow cone 10 has an unspecified shoulder with which the hollow shaft 8 is supported on the bearing block 6 via a thrust bearing 17.
  • the hollow shaft 9 is only indirectly supported in the bearing block 7, specifically via a sliding sleeve 18 with a collar 19 which is guided in the bearing block 7 so as to be longitudinally displaceable but not rotatable.
  • the longitudinal displacement takes place by means of an actuating lever 20 which is arranged on the side of the housing 1 and is fastened to a lever shaft 21.
  • the lever shaft is connected to the collar 19 of the sliding sleeve 18 via two link plates 22 and 23 shown in dashed lines and corresponding link pins.
  • the hollow cone 11 likewise has a shoulder (not designated in more detail) with which the hollow shaft 9 is supported on the collar 19 via a thrust bearing 24.
  • a thrust bearing 24 Although, with the exception of the thrust bearings 17 and 24, all other bearings are drawn as plain bearings, it goes without saying that the bearings in question can be designed as roller bearings and are preferably designed as needle bearings.
  • the coupling jaws 25 are conical surfaces at their two ends, which are essentially complementary to the conical surfaces of the hollow cones 10 and 11.
  • the coupling jaws 25 were produced in such a way that an initially closed rotary body, which corresponds to the hatched representation, was broken down into three sectors of equal size by axially parallel radial cuts. The cutting width was selected so that the coupling jaws can later be moved radially inwards to such an extent that all cleaning spirals and collets for which the machine in question is designed can be grasped.
  • the coupling jaws 25 are held at a distance in the unloaded state by means of tangential compression springs 27 which are held in corresponding blind bores in the coupling jaws.
  • the clutch shoes 25 are carried along by the driven hollow shaft 8 and in turn also drive the hollow shaft 9, so that slippage between the hollow cones and the clutch shoes does not occur.
  • the lever 20 downward the hollow cone 11 is displaced to the right, as a result of which the clutch shoes 25 deflect radially inward due to the cone surfaces.
  • these parts are taken along with a correspondingly increased pressure on the lever 20.
  • the front end of the housing is designated 28.
  • the part of a cleaning spiral 29 that is used for the cleaning process emerges from this end.
  • the front end 28 faces the opening through which the cleaning spiral 29 is inserted into the pipeline to be cleaned.
  • the housing has a connection coupling 31, parts of which belong to the housing 1, parts to a guide hose 32, which is a type of container for the end of the cleaning spiral 29 that is not in use.
  • the part of the connecting coupling 31 belonging to the guide hose is referred to as a plug body 33, although it is understood that the connection can be made not only by a plugging process, but also by a screwing process or a combined type of connection, such as a bayonet connection.
  • connection coupling 31 there is a cylindrical cavity 34 in the plug body 33, the axis of which coincides with the common axis A-A of the entire system.
  • a collet chuck 35 in which a collet 36 is rotatably mounted.
  • the collet is fixed axially in the bearing by means of circlips (unspecified).
  • an annular groove 37 is inserted into which a screw 38 engages radially, which has its counter thread in the plug body 33. In this way, the collet bearing 35 and thus the collet 36 is reliably fixed in the plug body 33.
  • collet 36 is coaxially aligned with respect to the common axis A-A of the system. While details of the collet are explained in more detail with reference to FIGS. 2 and 3, FIG. 1 shows the relative position of the collet with respect to the rotary coupling 26.
  • the rotary clutch 26 If, in the arrangement shown in FIG. 1, the rotary clutch 26 is actuated in the sense described above, the clutch jaws 25 first come into contact with the collet and take it along - initially by grinding - in the circumferential direction. The collet begins to rotate in the collet bearing 35. The part of the cleaning spiral 29 located within the collet has been omitted for the sake of clarity. When the rotary coupling 26 is actuated further, the collet 36 is then radially compressed and in this case lies against the cleaning spiral 29, causing it to rotate.
  • an index pin 40 is also arranged on the plug body 33, which engages in a corresponding housing bore (FIGS. 4 and 5). While the plug body 33 can be secured against rotation, in particular by the means according to FIG. 5, it is conceivable to provide the plug body according to FIG. 1 with a hollow cylindrical extension, which is only shown in broken lines and engages in a corresponding cavity in the housing 1.
  • the collet 36 is formed from a tube (seamlessly drawn precision steel tube) whose end remote from the collet bearing 35 is slit in the axial direction over a considerable length, namely three slots 41 distributed equidistantly on the circumference arranged.
  • three clamping jaws or fingers 42 are formed, which can be moved radially inward under the action of the rotary clutch 26.
  • the deformation that occurs here is only elastic due to the sufficient spring properties of the material.
  • the end 43 of the slots 41 lies at a point which is noticeably outside the coupling jaws 25, so that the rotary coupling cannot be blocked.
  • the width of the slots 41 is chosen so that a sufficiently large inward movement of the clamping jaws or fingers 42 is possible, in particular to be able to drive cleaning spirals 29 with different nominal diameters.
  • the plug-in body 33 consists of a closed part 33a and a longitudinally divided part 33b.
  • the longitudinally divided part 33b forms a type of clamp for clamping the guide tube 32.
  • the index pin 40 is mounted in the axial extension 44a, specifically in a housing 45, which also encloses a compression spring (not shown). The index pin 40 can be lifted upwards by a knurled disk 46. After lifting the index pin 40, it is possible to connect the plug body 33 to the housing 1 or to separate it again.
  • FIG. 5 It can also be seen from FIG. 5 that at the rear end of the housing 1, specifically above the axis A-A, there is a housing recess 47 which corresponds to the dimensions and position of the axial extension 44a. In the middle of the recess 47, a bore 48 is made, which serves to engage the index pin 40. At rounded diametrically opposite points of the rear opening of the housing 1, through which the cleaning spirals and / or the collets are inserted, two rounded pins 49 are arranged, which serve to guide and hold the plug body 33. For this purpose, there are two essentially complementary bores 50 in the plug body 33, with which the plug body 33 can be pushed onto the pins 49.
