Definitions

  • the invention relates to a cleaning device for cleaning pipelines according to the preamble of claim 1.
  • Such a cleaning device ( DE 10 2008 015 532 B4 ) has a handle that surrounds the spring shaft and can be moved in the longitudinal direction of the spring shaft.
  • the adjustable roller is adjusted with the handle in order to be able to move the spring shaft in both feed directions.
  • the handle tube is provided with a toothed rack into which a toothed sector engages. If the handle is moved along the spring shaft, the toothed sector is rotated via the toothed rack, whereby the adjustable roller is also rotated accordingly.
  • Such an adjusting device for the roller is structurally complex and requires a correspondingly large installation space. Since the handle surrounds the spring shaft, it is located at a point that is difficult to grip for the user, which makes working with the cleaning device more difficult.
  • the invention is based on the object of designing the generic cleaning device in such a way that, with a structurally simple and compact design, the adjustment of the roller is easily possible.
  • the handle extends transversely to the spring shaft.
  • the handle is in a convenient position for the user, who can therefore work with the cleaning device for a long time without getting tired. Since the handle is non-rotatably connected to the support that can be rotated in the housing opening, the roller can be adjusted in the desired direction by simply rotating the handle around its axis. This training results in a compact design of the housing and thus of the entire cleaning device. The rotation of the handle enables the direction of advance of the spring shaft to be changed very quickly.
  • the carrier is advantageously fork-shaped.
  • the carrier has two legs in which the ends of an axle are attached on which the roller is freely rotatably mounted. It is located between the legs of the wearer to save space.
  • the axle can be securely fastened in the two legs.
  • the carrier can also be designed in such a way that it has a recess in which the roller is accommodated. The axis which carries the roller extends in this case through this recess. Such a design also results in a very compact design, since even with such a carrier design the roller is essentially accommodated within the carrier and only protrudes over it so far that the roller can come into contact with the spring shaft.
  • the carrier is pressure-loaded in the direction of the spring shaft.
  • the carrier is under the force of at least one compression spring. It represents a structurally simple component that is inexpensive and easy to install.
  • the compression spring is formed by a disk spring assembly with which high compressive forces can be generated with a small structural volume.
  • At least one tensioning element is used to tension the compression spring.
  • a compact design is advantageous if the compression spring is housed within the tensioning element.
  • the compression spring is also protected from damage and / or contamination.
  • the compression spring rests on the carrier with a pressure washer in between.
  • the compressive force can thus be transmitted evenly to the carrier.
  • the tensioning element is at a small distance from the thrust washer, so that a reliable pressure force generation is guaranteed.
  • the tensioning element can also be designed in such a way that it comes to rest on the thrust washer when an intended maximum compressive stress is set. In this way, it can be achieved that an excessive contact pressure of the roller on the spring shaft is avoided.
  • the handle is penetrated by an axis through the clamping element.
  • the carrier for the third roller, the tensioning element and the handle preferably have a common one that runs transversely, preferably perpendicularly, to the spring shaft Axis.
  • Such a design has the advantage that the carrier, the tensioning element and the handle can be easily mounted.
  • the spring shaft which extends transversely to this, does not interfere with the assembly of these components.
  • the axis of the handle advantageously passes through the compression spring. This further contributes to the compact design of the cleaning device.
  • the use of the cleaning device by the user is advantageously facilitated if the rotary movement of the handle is limited in both directions by at least one stop in each case.
  • the role can thus be adjusted very easily into the two maximum adjustment positions. Between these maximum adjustment positions, the user of the cleaning device can set any desired intermediate position of the roller by turning the handle accordingly. This has an influence on the feed speed of the spring shaft.
  • the support of the spring shaft is formed by two further, fixed rollers which are opposite the adjustable roller.
  • the spring shaft is thus passed between three rollers which each bear against the spring shaft.
  • the three rollers advantageously have an angular distance of about 120 ° from one another.
  • the positionally fixed, freely rotatable rollers reliably support the spring shaft during its advance movement, with only low friction advantageously occurring.
  • the three rollers are preferably located approximately at the same height in the area of a through opening in the housing which connects a receiving space for a coupling piece of the drum with an opposite recess in the housing.
  • the three rollers resting on the spring shaft in this area are accommodated in the housing in a space-saving manner, with the spring shaft ensuring optimum support and optimum feed due to the rollers, which are approximately at the same height in relation to the longitudinal direction of the spring shaft.
  • the axes of rotation of the further, freely rotatable rollers are advantageously arranged inclined relative to the spring shaft both in the horizontal and in the vertical.
  • the axes of rotation are, based on the spring shaft, mirror-symmetrical to the spring shaft, viewed perpendicular to the spring shaft. Such a design results in a reliable advance of the spring shaft in both of its axial directions.
  • the cleaning device is used to clean pipes, for example to remove blockages in the pipes or limescale deposits.
  • the cleaning device is a hand-held device that is driven by a motor drive (not shown). Such a drive is advantageously a hand drill to which the cleaning device can be connected by the user.
  • the cleaning device has a rotatable drum 1 which receives a spring shaft 2.
  • the spring shaft 2 is also referred to as a cleaning spiral, which is pushed into the pipe to be cleaned in a manner still to be described.
  • the spring shaft 2 is wound up within the drum 1 in a known manner.
  • the drum 1 has a cylinder part 3 on which a cover 4 is placed on the front side and is detachably connected to it.
  • the cylinder part is thickened so that the fastening screws 5 are adequately held. These thickened areas also reinforce the drum 1.
  • the heads of the fastening screws 5 are countersunk in the cover 4.
  • the cover 4 has a circumferential narrow edge 6 which rests on the end face of the cylinder part 3. So that the cover 4 can be aligned easily with respect to the drum 1 or its cylinder part 3, it has a circumferential annular wall 7 with which the cover 6 rests against the cylindrical inner wall 8 of the cylinder part.
  • the circumferential edge 6 forms a radial flange which adjoins the annular wall 7 perpendicularly.
  • the middle area of the cover 4 is designed as a cone 9 which tapers in the direction of the interior of the drum 1.
  • the cone 9 is provided with a retaining bush 10 in which a drive pin 11 is fastened centrally. It protrudes over the retaining sleeve 10 and protrudes into one through the cone 9 formed recess 12 of the cover 4.
  • the drive pin 11 advantageously does not protrude beyond the end face of the drum 1.
  • the protruding part of the drive pin 11 is taken up by the chuck of the drill. With the clamped drive pin 11, the entire drum 1 is rotated about its axis.
  • the cylinder part 3 of the drum 1 merges into a conical part 13, which tapers in the same direction as the cone 9 of the cover 4 having.
  • a neck 16 of a bearing bush 17 protrudes into the through opening 15.
  • the neck 16 protrudes inwardly beyond the end piece 14 of the drum 1.
  • a nut 18 with which the bearing bush 17 is firmly connected to the drum 1 is screwed onto the protruding end of the neck.
  • the end piece 14 has a central recess 19 on its outside, into which the bearing bush 17 protrudes. It rests on the bottom and on the side wall of the recess 19 and is thereby aligned with respect to the drum 1.
  • the feed-through opening 15 and the opposite drive pin 11 are aligned with one another and in the axis of the drum 1.
  • the nut 18 pulls the bearing bush 17 firmly against the bottom of the recess 19.
  • the bearing bush 17 protrudes into a receiving space 20 of a housing 21 ( Fig. 3 ).
  • the receiving space 20 has an inner wall 22 which is formed, for example, from three inner wall sections 22a to 22c with different diameters.
  • the inner wall section 22a which adjoins a floor 23 of the receiving space 20, has the smallest diameter.
  • the middle inner wall section 22b has a larger diameter, which in turn is smaller than the diameter of the inner wall section 22c, which adjoins the free end face 24 of the housing 21.
  • the inner wall sections 22a to 22c each merge into one another via a circumferential radial shoulder 25, 26.
  • the radial shoulder 25 at the transition between the two inner wall sections 22a, 22b serves as a system for a pivot bearing 27 ( Fig. 1 ), which is an example of a ball bearing.
  • the axial width of the pivot bearing 27 advantageously corresponds to the axial width of the central inner wall section 22b.
  • the rotary bearing 27 is axially secured on the bearing bush 17 between a securing ring 30 and a circumferential radial shoulder 31.
  • the locking ring 30 is located approximately at the level of the radial shoulder 25, while the radial shoulder 31 of the bearing bush 17 is located approximately at the level of the locking ring 29 of the housing 21.
  • the bearing bush 17 is at a small distance from the floor 23 of the receiving space 20, so that the drum 1 can rotate unhindered about its axis when it is rotatably driven by the drill.
  • a through opening 32 opens into the bottom 23 of the receiving space 20 ( Fig. 4 ), through which the spring shaft 2 runs at a distance from the wall of the through opening.
  • the spring shaft 2 is also at a radial distance from the wall of the bearing bush 17, so that its advance movement is not impaired.
  • the housing 21 On its side facing away from the receiving space 20, the housing 21 has an end-face recess 33 which widens in the direction of the end face 34 of the housing 21 and is connected to the receiving space 20 through the through-opening 32.
  • the spring shaft 2 protrudes centrally through the recess 33. Due to the conical design of the recess 33, the spring shaft 2 can move transversely when the cleaning device is used perform without it coming into contact with the wall of the recess 33.
  • the housing 21 is provided with a bearing opening 35 which is located radially to the through opening 32 and in which a carrier 36 is rotatably mounted.
  • the carrier 36 is advantageously fork-shaped and has two legs 37, 38 lying parallel to one another, in which an axis 39 is attached.
  • a roller 40 is freely rotatable on it and protrudes over the support legs 37, 38 and protrudes into the through opening 32 in such a way that it can be brought to rest on the spring shaft 2.
  • the housing 21 is provided with a protruding neck 41, which is advantageously formed in one piece with the housing 21.
  • a cylindrical extension 42 of an adjusting wheel 43 protrudes into the cylindrical neck 41.
  • the extension 42 is screwed into the neck 41, which protrudes from a rotary handle 44 which is located in the area outside the neck 41.
  • the projection 42 rests flat on the carrier 36 with a pressure disk 45 interposed.
  • At least one compression spring 46 is accommodated in the extension 42 and loads the carrier 36 in the direction of the spring shaft 2 via the pressure disk 45.
  • the compression spring 46 is advantageously formed by a spring assembly, in particular a disc spring assembly, which is supported with one end on the pressure disk 45 and with the other end on an annular shoulder 47 which is provided in a receiving space 48 of the extension 42 that accommodates the compression spring 46.
  • the extension 42 is at a small distance from the pressure disk 45, so that a reliable application of pressure to the carrier 36 is guaranteed.
  • the disk spring assembly 46 can also rest directly on the carrier 36, so that a pressure washer can be omitted.
  • the pressure force is set with which the roller 40 rests on the spring shaft 2 via the compression spring 46. Since the extension 42 is screwed into the neck 41, the spring force can be continuously adjusted and thus adapted to the respective circumstances.
  • the carrier 36 can be rotated about its axis by means of a handle 49.
  • the handle 49 extends perpendicular to the spring shaft 2.
  • the handle 49 has an axis 50 which passes through the rotary handle 44, the compression spring 46 and the pressure disk 45 and is fastened in the carrier 36. If the handle 49 is rotated about its axis, the carrier 36 is correspondingly rotated about its axis.
  • the roller 40 is shown in FIG Figs. 1 to 5 from above on the spring shaft 2.
  • the cleaning device has two further rollers 51, 52 which are freely rotatable about their axes. These rollers 51, 52 each sit on an axle 53, 54 which is fastened in the housing 21 in such a way that the rollers 51, 52 protrude into the through opening 32 and lie against the spring shaft 2. How out Fig. 3 results, the rollers 40, 51, 52, viewed in the axial direction of the through opening 32, lie in such a way that their areas of contact with the spring shaft 2 are at an angular distance of approximately 120 °.
  • the axes 53, 54 are fastened in the housing 21 in such a way that the rollers 51, 52 seated on them protrude into the through opening 32.
  • the axes of rotation 55, 56 ( Fig. 5 ) of the rollers 51, 52 are, viewed perpendicular to the spring shaft 2, on both sides of the spring shaft 2 at an acute angle to each other and to the longitudinal axis 58 of the spring shaft 2. Seen from above on the spring shaft 2 ( Fig. 5 ) the axes of rotation 55, 56 intersect one another in the longitudinal axis 58 of the spring shaft 2. In addition, the axes of rotation 55, 56 are related inclined on the axis 58 of the spring shaft 2 in the area of the through opening 32 ( Figures 3 to 5 ).
  • the two rollers 51, 52 are, seen in plan view of the spring shaft 2 ( Fig. 5 ), mirror-symmetrical to one another, based on the longitudinal axis 58 of the spring shaft 2.
  • the axis of rotation 57 of the roller 40 can be set in different positions relative to the spring shaft 2 by rotating the carrier 36. By rotating the carrier 36 about its axis, the axis of rotation 57 is adjusted to different inclined positions with respect to the axis of the spring shaft 2, in a plan view of the spring shaft 2 according to FIG Fig. 5 seen. In this top view, the axis of rotation 57 of the roller 40 forms an angle ⁇ with the axis 58 of the spring shaft 2. As a result, an axial force is exerted on the spring shaft 2, which means that the spring shaft 2 is extended when the drum 1 is driven. Depending on the position of the roller 40, the spring shaft 2 is pushed forwards or backwards.
  • the carrier 36 can be rotated about its axis in such a way that the axis of rotation 57 of the roller 40 with the axis 58 of the spring shaft 2 encloses the angle ⁇ in the other direction.
  • the roller 40 adjusted in this way ensures that the spring shaft 2 is moved back into the drum with the drum 1 rotating in the same direction.
  • a reversal of the direction of rotation of the drilling machine or the drum 1 is therefore not required to retract and extend the spring shaft 2.
  • the user of the cleaning device only has to turn the handle 49 about its axis in such a way that the axis of rotation 57 of the roller 40 is either in the one (dash-dotted line in Fig. 5 ) or the other direction (dotted line in Fig. 5 ) runs relative to the axis 58 of the spring shaft 2, viewed from above on the spring shaft ( Fig. 5 ).
  • the roller can be pivoted between the two end positions without any problems. If the roller 40 is pivoted into a central position in which its axis of rotation 57 is parallel to the axis 58 of the spring shaft 2, the spring shaft 2 stops and is not moved further axially. This allows the user to react very quickly if the resistance in the pipeline to be cleaned should become too high. As a result of the simple rotary movement of the handle 49, the switchover between forward and backward movement of the spring shaft 2 can also be carried out within a very short time, so that even stubborn deposits in a pipe can be reliably removed.
  • the handle 49 lies transversely to the spring shaft 2, the housing 21 can be brought close to the pipe to be cleaned during the cleaning process without the adjustment of the roller 40 being impaired.
  • the handle 49 serves not only to reverse the axial movement of the spring shaft 2, but also to hold the cleaning device. In particular, this enables fatigue-free work with the cleaning device.
  • the pressing force with which the roller 40 rests on the spring shaft 2 can be adjusted with the rotary wheel 44.
  • the pressure force of the compression spring 46 can be adjusted with the rotary wheel 44.
  • the carrier 36 and thus the adjustable roller 40 can be rotated, for example, by approximately ⁇ 20 ° from a central position in which the axis of rotation 57 is parallel to the longitudinal axis 58 of the spring shaft 2.
  • the two end positions can be defined by stops so that the user can easily get into these two end positions. Since intermediate positions of the roller 40 can also be set with the handle 49, the feed speed of the spring shaft 2 can be continuously adjusted in both directions.
  • the handle 49 lies with a cone piece 59 ( Fig. 4 ) on the face of the rotary wheel 44. Because the cone piece 59 has a much smaller diameter than the handle 49, the handle 49 can easily be rotated relative to the rotary wheel 44.
  • the housing 21 Since the handle 49 runs transversely with respect to the spring shaft 2 in the area of the through opening 32 or the recess 33, the housing 21 has only a short length in the axial direction.
  • the three rollers 40, 51, 52 can be accommodated in the small housing 21 without any problems. Since the rollers 51, 52 are arranged in a non-adjustable manner in the housing 21, no adjustment devices are required for them either, which contributes to the compact shape of the housing 21.
  • the handle 49 is easy to assemble since it is inserted into the housing 21 transversely to the spring shaft 2.
  • the handle 49 and the spring shaft 2 can be assembled and disassembled independently of one another. If, for example, the spring shaft 2 is damaged, it can simply be replaced without the handle 49 having to be dismantled or dismantled.
  • the handle 49 can also be easily exchanged if necessary.
  • the spring shaft 2 is not affected by the replacement of the handle 49.
  • the diameter of the rotary wheel 44 is only slightly smaller than the outer diameter of the housing 21.
  • the neck 41 has a smaller diameter than the rotary wheel 44 and the housing 21, which contributes to the compact design of the device.
  • the handle 49 is also designed in such a way that, viewed in its axial direction, it does not protrude over the rotary wheel 44.
  • the handle 49 is sufficiently long that it can be comfortably grasped by the hand of the user and rotated about its axis in order to adjust the roller 40.
  • the handle 49 can be made of any suitable material.
  • the handle 49 is preferably made of a suitable plastic.
  • the axle 50 consists of a metallic material and is embedded in the handle 49 at its end facing away from the roller 40.
  • the spring shaft 2 At its front end in the feed direction, the spring shaft 2 carries in a known manner a corresponding cleaning tool with which the deposits in the pipe to be cleaned can be removed.
  • the cleaning device is characterized by its simple structural design.
  • the conversion or adjustment of the roller 40 is possible in a simple manner because it is mounted in the carrier 36, which is only rotated about its axis by means of the handle 49.
  • the rotary movement of the handle 49 is converted directly into the rotary movement of the carrier 36, so that complex intermediate transmission elements are not required, which would increase the installation space and thus the size of the housing 21.
