Definitions

  • the invention relates to a hand-held cleaning device for cleaning pipelines by means of a spring shaft, equipped with a motor, a drum for receiving and outputting the spring shaft and a transmission housing in which a plurality of radially acting on the spring shaft rollers are arranged with axes, the are aligned with radial distances at angles to the axis of the spring shaft.
  • cleaning tools that can be attached to the spring shafts via appropriate couplings.
  • These include cutting heads, club drills, return drills, hopper drills, crosshead drills, blade head drills, carbide drills, sawtooth cutting heads, root cutters, fork heads, grease drippers, chain spinner heads with and without spikes, carbide heads, etc.
  • the feed rate is changed by controlling the engine speed.
  • a motor retreat The spring shaft is only possible by reversing the direction of rotation of the drum.
  • the locking body are replaced by easily replaceable leaf springs and the withdrawal of the spring wave can be effected by reversing the direction of rotation of the engine is in the EP 407 327 B1 or their translation DE 690 00 316 T2 disclosed.
  • the rollers have the effect of driving rollers.
  • To turn on and off one of the three rollers is mounted radially movable on the inside of an angle lever.
  • a changeover of the transport direction of the spring shaft from extension to retraction is possible here exclusively by switching the direction of rotation of the spring shaft.
  • the drum can be stored in the different lengths of the spring shaft, stopped and restarted in the opposite direction.
  • the device does not require reversal of the direction of rotation of the drum and spring shaft, but because of the many fits consuming in the production and has a long extension. Most importantly, to reverse thrust, the operator must move one hand around the turntable for a large pivotal path, while the weight of the cleaning machine must be picked up by the other hand.
  • each group of rollers are aligned in the same direction and at an acute angle to the axis of the spring shaft ("snake"), and the thrust direction of the spring shaft can be reversed without changing the direction of rotation of the drum and spring shaft.
  • the thrust reverser is carried out either by a one-piece, centrally mounted rocker with two lever arms or by two oppositely projecting levers which are pivotable about a common axis which extends transversely to the spring shaft.
  • the device is arranged at the end of a guide tube for the spring shaft, so that it can not be actuated by a push handle, which is mounted on an axle fixed hollow shaft of a motor-driven drum and also for manual mounting of the machine.
  • the invention is based on the object to provide a cleaning device of the type described above, which manages with a smaller number of precision parts, a metered transport speed of the spring shaft in both axial directions and a fast switching of the transport direction of the spring shaft without reversing the direction of rotation of the drum allowed without that in this case a displacement of a hand of the operator would have to be done on a protruding movable lever, while reducing the risk of fatigue for the Particularsperscn despite the manual operation is reduced.
  • the invention wurd said object was fully achieved, and it is a cleaning device of the type described above improved by the fact that it requires a smaller number of precision parts, a metered transport speed of the spring shaft in both axial directions and a fast switching of the transport direction of the spring shaft Without reversing the direction of rotation of the drum allows, without this a displacement of a hand of the operator would have to be done on a protruding movable lever, while reducing the risk of fatigue for the operator despite the manual operation is reduced.
  • the invention is based on the surprising finding that the task can be achieved with only three rollers, of which only one is adjustable.
  • FIG. 1 a complete cleaning device 1 is shown, to which a motor 2 with a handle 3 and a switch 4 belong, as is also known from hand drills ago.
  • a rotatable drum 5 is attached for receiving a spring shaft 6.
  • the drum 5 has a fixed attached guide tube 7 ( FIG. 2 ), which is coaxially surrounded by a handle tube 8, which is provided in the direction of the drum 5 with a funnel-shaped hand guard 9.
  • This hand guard 9 partially covers the likewise funnel-shaped end wall 5a of the drum 5.
  • the handle tube 8 merges into a cylindrical chamber 10, in which the complete adjusting mechanism for the movement of the spring shaft 6 is housed.
  • An adjusting knob 11 is used to set a pressing force of the adjustable roller to the two stationary rollers, which will be explained in more detail below.
  • FIG. 1 in each case only the end of this spring shaft 6 is shown, and at the local thickening it can be seen that this end already has a tool function.
  • the top right box shows the options for the direction of rotation of the motor shaft, and "R” stands for clockwise rotation and “L” for counterclockwise rotation. This switching is not mandatory for the main function of the invention, but increases the flexibility of the device.
  • the terms “clockwise rotation” and “counterclockwise rotation” refer to the viewing direction of the operator, ie to the viewing direction via the drum 5 to the working tool at the end of the spring shaft 6. The same applies to the course of the winding of the spring shaft 6.
  • the axis of the adjustable roller is parallel to the axis of the spring shaft 6 (again FIG. 5 ), so that no axial movement of the same takes place. If the handle tube 8 and the drum 5 are pushed together (upper illustration), the spring shaft 6 is withdrawn. If the handle tube 8 and the drum 5 are pulled apart (lower illustration), the spring shaft 6 is advanced.
  • the lower left box explains the function of the adjustment knob 11: By the clockwise rotation in the direction of arrow "+” is an amplification of the contact pressure of the adjustable roller to the two stationary rollers. By turning it to the left in the direction of the arrow "-”, the contact force of the adjustable roller is reduced to the two stationary rollers. All these functions will be explained in detail below in connection with the remaining figures, in which the previous reference numerals are retained.
  • the FIG. 2 shows a support tube 12 with grooves 12 a, which is arranged in the assembled state between the guide tube 7 and the handle tube 8.
  • the grooves 12a are intended to intercept about entrained by the spring shaft 6 during retraction impurities to avoid binding of the handle tube 8.
  • the support tube 12 terminates in a concentric circular disc 13, emanating from the three axially parallel and equidistant webs 14. These webs 14 serve to receive a high-strength gear housing 15, which has three grooves 16 on the circumference, which are formed according to cross section and spatial distribution complementary to the webs 14.
  • the transmission housing 15 has a cavity 17 whose shape and purpose will be explained in more detail below.
  • the switching mechanism 20 viewed from the outside inwards, the aforementioned knob 11, an intermediate housing 21 with two recesses 21 a and 21 b, of which one 21 a for the hub 11 a of the knob 11 and the other 21 b for receiving a bearing block 22 with the movable roller 23 is used.
  • the bearing block 22 has a pin 22 a, which is surrounded by a spring assembly, not shown here.
  • the contact pressure to the other two, fixedly mounted rollers 24 and 25 regulate.
  • the handle tube 8 For the purpose of a linear and paraxial, but rotationally fixed displacement of the handle tube 8 with the attached or molded-in chamber 10, the latter is provided with an axially parallel bead 10a, which engages in a complementary groove 26 of the gear housing 15.
  • the chamber 10 has in its cylindrical wall a recess 27, one edge region of which is accompanied by an axis-parallel row of teeth 28.
  • the transmission housing 15 is provided with a radial recess 29.
  • the recesses 27 and 29 form a passage through which the switching mechanism 20 can be inserted radially.
  • a tooth sector 30, which is connected to the bearing block 22, in engagement with the row of teeth 28, so that by the displacement of the handle tube 8, those movements can be performed, based on the FIG. 1 have been described. It turns the bearing block 22 about its pin 22a.
  • FIG. 5 shows a longitudinal axis "AL", which is also the system axis and the axis of the spring shaft 6 and which determines the viewing direction here.
  • the rollers 23, 24 and 25 are arranged with their axes A1, A2 and A3.
  • the rollers 24 and 25 are spatially fixed with their inner bearing rings by screwing on not visible here oblique surfaces within the gear housing 15.
  • the spatial position has been chosen so that their axes A2 and A3 intersect in a virtual point "P", but at the same time run obliquely and tangentially to a virtual cylindrical surface, which concentrically surrounds the axis "AL" with a corresponding distance.
  • rollers 24 and 25 are arranged mirror-symmetrically to each other, and rotate, driven by the contact with the spring shaft 6, in opposite directions of rotation. This results in frictional forces, one component of which runs parallel to the axis "AL.” These components extend in opposite directions, and thus do not generate any axial movements of the spring shaft 6 due to a force equilibrium.
  • FIG. 5 shows a top view from above in the direction of the pivot axis "AS-AS”, but these figures are even more abstracted.
  • the pivotable roller 23 is shown in its two end positions, by an angle " ⁇ " of, for example, about 20 degrees, in each case about the pivot axis "AS-AS", starting from the central position FIG. 5 , twisted ..
  • the spatial position of the teeth 28/30 is chosen so that the movement directions of the handle 3 and the drum 5 to facilitate the operation the handle tube 8 coincides with the transport directions of the spring shaft 6.
