Definitions

  • the invention relates to a pipe cleaning device with a probe that can be inserted into a tube and a roller set comprising at least two rollers that can be rolled against one another on the probe and reversed in such a way that they either advance or retract the probe.
  • a probe is understood here to mean an elongated, preferably elastically flexible structure of essentially constant cross section, which is suitable for being inserted into a tubular line or a bore in order to clean it or otherwise treat it from the inside.
  • the term probe accordingly includes helical spring-like coils made of metal or plastic wire as well as hoses with which a fluid can be supplied under pressure to a tool arranged at the end of the hose.
  • an essentially rigid lance can be used instead of a hose; this should therefore also fall under the term probe.
  • a tool can be provided as a tool, which directs the fluid in one or more sharp jets against the inner wall of the pipeline or bore, or a drilling tool which is driven and / or cooled by the fluid.
  • the pivotal movement of the roller carrier serves the sole purpose of adjusting the axial direction of the drum, and thus the direction in which the probe leaves the drum.
  • the rollers have a neutral position in which their axes of rotation extend parallel to the probe passed between them. In this neutral position, the rollers resist longitudinal movement of the probe when the drum and probe are rotated by a motor associated with the drum. Starting from the neutral position, the rollers can be inclined by the same amount, but in opposite directions, optionally in two different directions, so that, without being directly driven, they can be fed at a given direction of rotation of the drum and the probe depending on the direction of the inclination -forcing retraction of the probe rotating between them.
  • a feed movement of the probe can be easily converted into a retraction movement and vice versa by changing the inclined position of the rollers, so that, for example, a pipe section in which the tool attached to the probe encounters an obstacle is traversed several times can without having to reverse the direction of rotation of the drum.
  • the invention is based on the knowledge that a hammering or pulsating additional movement, which is superimposed on the advancing or retracting movement of a probe, can considerably increase the effect of tools of the most varied kind arranged on the probe. This is especially true for the effects of high pressure water jets that emerge from a nozzle head at the end of a tubular or lance-shaped probe.
  • the increase in effectiveness apparently has to do with the fact that rapidly successive reciprocating movements of the nozzle head or other pipe cleaning tool contribute to the rapid removal of contaminants which the tool has detached from the pipe wall.
  • the invention is therefore based on the object of providing a pipe cleaning device which is capable of giving a probe gentle, overlapping, hammering or pulsating movements during a feed or retraction movement of a certain average speed with little effort.
  • At least one of the rollers can be driven in rotation by a roller drive motor.
  • the roller drive motor enables the probe to be given a feed or retraction movement even without rotating the probe.
  • a rotatable drum for the probe is therefore not necessary; for this reason alone, the feed drive according to the invention can be designed simply, which has the further advantage that it is easy to transport.
  • the invention is also applicable to a feed drive in which the actual feed or retraction movement, as in the known feed drive, consists in the probe being rotated about its own axis, preferably in the form of a lance, and thereby screwed between inclined rollers.
  • the additional drive gives the probe an at least approximately rectilinear, periodic additional movement, the frequency and amplitude of which depend on the design of the additional drive and can thus be adapted to the respective application.
  • the invention can further build on the feature of the known feed drive that the rollers are mounted on a roller carrier which is pivotable on a frame about an axis which extends at least approximately at right angles to the probe guided between the rollers.
  • the probe is guided according to the invention between the rollers at a distance from the pivot axis of the roller carrier and the additional drive is an eccentric or crank drive driven by the roller drive motor, which periodically swings the roller carrier back and forth.
  • the pivotability of the roller carrier does not have the purpose of setting the probe in a specific direction, but rather becomes the roller carrier pivoted back and forth to give the rollers and thus the probe the desired periodic additional movement.
  • the last described embodiment of the invention can also build on the feature of the known feed drive that the roller drive motor is attached to the roller carrier and the axes of rotation of the rollers extend at an angle to the pivot axis of the roller carrier.
  • a further development of the invention provides that a wheel is arranged coaxially with the roller driven by the roller drive motor, which wheel engages with a pinion of smaller diameter mounted on the roller carrier and drives a crank pin via this, which is connected to a connecting rod by a connecting rod pin connected to the frame is connected.
  • roller drive motor is fastened to the frame and drives a wheel whose axis of rotation coincides with the pivot axis of the roller carrier, and that one of the rollers is in gear connection with this wheel.
  • This development has the advantage that the inert mass of the roller carrier is particularly low, which contributes significantly to smooth running and a long service life of the feed drive according to the invention.
  • the last-described development of the invention can be designed in a particularly simple manner in that the wheel is a friction wheel and the rollers are each mounted on a journal which is parallel to the axis of rotation of the wheel and which is guided radially displaceably with respect to the wheel on the roller carrier and towards the wheel is biased.
  • the wheel can also be a gear and mesh with a pinion that is firmly connected to the one roller.
  • the maximum speed of the reciprocating movement of the roller carrier is preferably greater than the speed at which the rollers roll on the probe. In this way, the advancing movement of the probe is not only accelerated and decelerated periodically, but temporarily transformed into a withdrawal movement. Conversely, a gradually advancing withdrawal movement of the probe is not only accelerated and decelerated by the back and forth additional movement, but is periodically converted into a feed movement.
  • the additional drive has a second roller set comprising at least two rollers that can be rolled on the probe and that are synchronous can be driven with the rollers of the first roller set in a direction of rotation in which they endeavor to move the probe in the opposite direction to the feed direction of the first roller set, and that the rollers of the first roller set have a tread that can be rolled on the probe only in a first angular range, while The rollers of the second roller set have a tread that can be rolled on the probe only in a second angular range that is at least approximately complementary to the first angular range and of a different size.
  • This embodiment is characterized by a particularly smooth running, since all the rollers can rotate continuously and there is also no need for any mass that is periodically accelerated and decelerated.
  • the rollers are preferably each firmly connected to a gear wheel and are in a slip-free gear connection with one another via these gear wheels.
  • the pipe cleaning device shown in Fig. 1 to 3 has the task of either advancing a probe 11, for example vertically downwards, or withdrawing it, for example vertically upwards, and thereby giving it a back and forth additional movement of high frequency.
  • the device includes a frame 12 to which a lower guide tube 13 for the probe 11 is attached.
  • the frame 12 can be arranged, for example, on a tube sheet of a boiler, the tubes of which are to be cleaned.
  • the frame 12 can be attached to a trolley, carriage or the like, and also in such a way that the guide tube 13 lies obliquely or horizontally and the probe 11 is accordingly advanced and withdrawn in a direction deviating from the vertical.
  • an axis 16 is arranged at a distance from and at a right angle to the guide tube 13.
  • a rocker 17 is mounted, which belongs to a part of the pipe cleaning device which is referred to as roller carrier 18 and which can be moved back and forth with respect to the frame 12.
  • a reduction gear 19 is attached to the rocker 17, to which a roller drive motor 21 is flanged.
  • the reduction gear 19 produces a preferably continuously adjustable reduction ratio between the roller drive motor 21 and an output shaft 22, on which a gear 23 and a roller 24 are fastened.
  • a crankshaft 28 is mounted parallel to the output shaft 22, on which a pinion 29 meshing with the gear 23 and a crank 31 are fastened.
  • the crank 31 has a crank pin 32 on which a connecting rod 33 is mounted.
  • the connecting rod 33 is adjustable in length in the manner of a turnbuckle and connects the crank pin 32 to a pin 34 fastened to the frame 12.
  • a clamping jaw 36 is also pivotally mounted about an axis 37 parallel to the output shaft 22.
  • a roller 38 is mounted on the clamping jaw 36, the axis of which is also parallel to the output shaft 22.
  • the roller 38 corresponds in shape and size to the roller 24; both rollers 24 and 38 are made of plastic and are designed in the manner of rope pulleys so that they can gently guide and drive the probe 11.
  • the probe 11 can additionally be guided in an upper guide tube 46 fastened to the clamping jaw 36, which has an interruption 47 so that the rollers 24 and 38 can rest against the probe 11.
  • the feed drive described works as follows: If the roller drive motor 21 is turned on so that it. 1 drives the roller 24 clockwise, then the probe 11 is advanced downward. At the same time, the gear 23 drives the crankshaft 28 via the pinion 29 and this forms, together with the crank 31 and the connecting rod 33, an additional drive which swivels the rocker 17 back and forth about the axis 16, so that the rollers 24 and 38 have an im substantially vertical up and down additional movement is given, which is approximately straight due to the relatively large distance of the rollers from the axis 16 and overlaps the rotation of the rollers. As a result, the probe 11 performs an upward and downward additional movement during its downward feed movement.
  • the feed drive for a probe 51 shown in FIGS. 5 and 6 has a frame 52 which can also be provided with a chassis (not shown); however, this feed drive is so light that it can easily be carried to its place of use.
  • a guide tube 53 for the probe 51 and a reduction gear 54 with a flanged roller drive motor 55 are fastened to the frame 52.
