Definitions

  • the invention relates to a washing machine for fire hoses, which contains, between a hose inlet opening and a hose outlet opening, at least a pair of brush rollers arranged parallel to one another on both sides of the hose path and drivable for a rotational movement, which have an axial length that allows the simultaneous passage of at least two hoses.
  • a washing machine of this type is known for example from the older patent application P 42 20 059.8 or DE-PS 38 17 778.
  • the distance between the two brush rollers of each pair of rollers can be changed so that, in contrast to the hose material, rigid coupling pieces at the hose ends, the diameter of which is larger than the diameter of the actual hose, can pass between the brush rollers.
  • the present invention is therefore based on the object of providing a washing machine according to the preamble which enables continuous washing of all the hoses passing through the washing machine next to one another, even if the coupling pieces of the various hoses do not reach the roller brushes at the same time.
  • At least one of the brush rollers is divided in the axial direction independently of one another in the direction of the other brush roller or away from the individual rollers which are each assigned to a hose to be washed.
  • roller spacing is increased only on the respective individual roller to which the coupling piece of the hose washed by it reaches, while the at least one other individual roller remains unactuated and the washing of the hose treated by it continues unchanged.
  • the individual rollers expediently bear against the hoses passed through under their own weight and / or a spring force, such that the respective hose including its coupling pieces forms a motion control for the individual roller which automatically adjusts its position to the current hose cross section.
  • a sensor or the like instead of this, one could in principle also use a sensor or the like.
  • the aforementioned possibility of controlling the movement by means of the hose in question itself has the advantage that the individual roller can move at any time can adapt to the current hose cross-section and thus also to the coupling piece, so that this is also brushed and cleaned.
  • the effort associated with external control is eliminated.
  • a further expedient measure consists in the fact that in the event that only one brush roller of the at least one pair of brush rollers is divided into individual rollers which are each arranged to be movable, the space existing in the axial direction between two individual rollers protrudes radially from that of the other brush roller Bristle ring is assigned.
  • This bristle ring represents a lateral guide for the two hoses running past it.
  • the dirty fire hoses 1, 2 coming from an insert are first placed in a soaking container 3 filled with water, which is next to a washing machine 4.
  • the hoses 1, 2 are made of flexible material and each have a coupling piece 5 or 6 at their two ends, which is made of metal and has an essentially circular circumference.
  • the hoses 1, 2 then pass through the washing machine 4, the housing of which has a hose inlet opening 7 on the one hand and a hose outlet opening 8 on the opposite side, the two openings 7, 8 in the exemplary embodiment being closed by a brush curtain 9 and 10 divided halfway up.
  • the hoses enter and exit on each side between the two half-curtains, the two half-curtains resulting in the curtain 9 at the hose inlet opening 7 bending inwards and the two half-curtains of the outlet-side curtain 10 bending outwards.
  • the washing machine contains at least one pair of mutually parallel axes arranged on both sides of the hose path 13
  • Brush rollers 11, 12, which are assigned to the top and bottom of the hoses and are driven to rotate during operation by means of a drive device.
  • the two brush rollers 11, 12 rotate in opposite directions in the direction of the arrows and, at the location of the hoses running through, opposite to the hose passage direction 13.
  • the brush rollers 11, 12 thus grip the hoses and remove the dirt from the outside. This takes place with the supply of washing water into the washing machine, it being expediently provided that the washing machine contains washing water outlet nozzles which open out in its interior for washing water which is under increased pressure or high pressure.
  • a water supply pipe 14 is indicated schematically, from which the washing water emerges at spaced nozzles.
  • the washing machine 4 is set up so that its hose outlet opening 8 is adjacent to a care table 15.
  • a carriage 16 is arranged to be movable along the care table 15, so that the hoses emerging from the washing machine can be pulled onto the care table 15 with the help of the carriage 16.
  • the front coupling pieces 5 of the hoses are each attached to a coupling holder 17 carried by the chassis 16. Since the direction of travel 18 of the undercarriage and thus the direction of travel 13 of the tubes in the same direction is opposite to the direction of rotation of the brush rollers 11, 12, the tubes are tightened by the brush rollers 11, 12 during washing.
  • the hoses could also be held by hand during the washing process, the direction of flow in this case being opposite, since the rotating brush rollers pull the hoses in the opposite direction of arrow 13 would, so that the operator only has to guide the tubes and hold them, so to speak, braking.
  • a particularly useful mode of operation is that after the initial insertion of the hoses into the washing machine and hanging the coupling pieces 5 into the coupling holder 17, the undercarriage 16 first moves to the washing machine 4 so that the coupling pieces 5 held by the coupling holders 17 from the exit side get to the brush rollers 11, 12 and are washed by them. Then the direction of travel of the trolley 16 is switched in the direction 18 so that the hoses are pulled completely through the washing machine.
  • This sequence of movements can be automated by means of a suitable control device for the chassis 16.
  • the undercarriage 16 towards the washing machine the hose in question or its coupling piece is moved towards it by the rotating brush rollers
  • the hose care system shown in FIG. 1 also includes a control panel 19 which carries the control elements for operating the washing machine and the undercarriage.
  • the brush rollers 11, 12 are of such a length in the axial direction that at least two hoses can be passed through the washing machine side by side at the same time.
  • the exemplary embodiment involves washing two tubes at the same time permitting roller length.
  • At least one of the brush rollers in the practical embodiment only the brush roller 11 arranged in the vertical direction at the top, is divided in the axial direction into individual rollers which can be moved independently of one another towards or away from the other brush roller 12, each of which is assigned to a hose to be washed are.
  • the lower brush roller 12 could also be subdivided into individual rollers or both brush rollers could be independent individual rollers.
  • the other brush roller 12 is expediently not subdivided, it being possible for it to be arranged to be either stationary or overall movable in a manner similar to the individual rollers of the brush roller 11.
  • each tube has a roller distance that can be changed independently of the other tubes, so that it does not matter whether tubes of different cross-sections are washed at the same time or whether, for example, the end coupling piece has reached the washing machine in one of the tubes.
  • Each hose always has an uninterrupted grip on the bristles of the brush rollers from both sides over the entire length of the hose.
  • the two brush rollers 11, 12 are located in their idle state, ie there are no hoses inserted.
  • the bristles of the two brush rollers mesh somewhat against one another, as shown in FIG. 2. For reasons of illustration only, a small gap was left in FIG. 3 between the two brush rollers.
  • FIG. 4 shows the situation in which the two hoses 1, 2 are pulled through the washing machine with their flexible hose jacket.
  • the two individual brushes 20, 21 are practically at the same distance from the brush roller 12.
  • the individual rollers 20, 21 can rest against the hoses passed through under their own weight. Instead of this or in addition, however, a spring force can also act on the individual rollers, so that the individual rollers are pressed correspondingly stronger or weaker against the hoses. In this way, the cleaning effect can be increased or a more gentle hose treatment results. In both cases and in the combined case, it results that the respective hose forms a motion control for the individual roller which automatically adjusts its position to the current hose cross section.
  • this movement control also enables the above-mentioned expedient operating mode, in which the front coupling piece is washed.
  • the flexible hose material is relatively uneven. Accordingly, the individual rollers 20, 21 are in constant motion, since they adapt to any unevenness in the hose. In this context, it may be advantageous that the individual rollers are supported by vibration dampers, in particular gas springs. Such a gas spring 22 assigned to the single roller 20 is indicated in FIG. 2.
  • the individual rollers 20, 21 have a different axial length. In this way, hoses of different diameters can be washed, the length of the longer individual roller being adapted to the largest possible hose cross section. Of course, both individual rollers could be designed with this length, but the washing machine would then be made correspondingly wider.
  • This intermediate space 23 is assigned a bristle ring 24 protruding in the radial direction on the other brush roller 12.
  • This bristle ring 24 forms a lateral guide for the hoses 1, 2 passing through the washing machine on both sides of it, even if it does not engage in the intermediate space 23 when the hoses pass through the hoses due to an excessive distance from the individual rollers 20, 21.
  • the stationary or generally movable brush roller 12 thus has successive sections in the axial direction, namely the two outer brush sections 25, 26, each of which is opposite a single roller 20 or 21, and the section arranged between the outer brush sections and forming the bristle ring 24.
  • the bristle ring 24 is not shown in FIG. 2 for the sake of clarity. With regard to FIG. 2, it is otherwise to be added that the raised position of the individual roller 20 corresponding to FIG. 5 is indicated by dash-dotted lines.
  • the movement with which the individual rollers 20, 21 move towards or away from the other brush roller 12 is expediently a pivoting movement. In principle, however, it could also be a different movement, for example a linear movement.
  • each swivel holder 27, 28 forms two holding arms 29, 30 and 31, 32, which grip over the end faces of the associated individual roller and support them.
  • a particularly simple arrangement results from the fact that the swivel holders 27, 28 are mounted on a continuous swivel axis 33 common to all swivel holders.
  • the pivot axis 33 can simultaneously form a drive shaft 34 or be penetrated by a drive shaft, the drive of the individual rollers 20, 21 for the rotational movement of this drive shaft is derived.
  • the drive shaft 34 coinciding with the swivel axis 33 only has to be driven on one side.
  • a motor 35 arranged laterally at the bottom of the washing machine housing drives a belt pulley 37 by means of a first belt drive 36, which in turn drives two further belt drives, namely a belt drive 38 driving the continuous brush roller 12 for its rotational movement and a further belt drive 39, which drives one of the drive shafts 34 of the individual rollers 20,21 upstream drive gear 40 drives.
  • the drive gear 40 meshes with a follower gear 41 which is rotatably connected to the drive shaft 34.
  • the continuous drive shaft 34 in turn drives, in the region of each swivel holder 27 or 28, a belt drive 42 or 43 assigned to the relevant individual roller 20 or 21, via which the relevant single roller is driven for its rotational movement.
  • the two belt drives 42, 43 each assigned to a single roller are located on the opposite ends of the two swivel holders 27, 28.
  • the motor-side drive parts can be partitioned off from the washing room of the washing machine containing the brushing rollers by a partition.
  • the initial insertion of the hoses into the washing machine can be facilitated in that one of the brush rollers, in the exemplary embodiment the brush roller 11 divided into the individual rollers 20, 21, is arranged on a machine housing upper part 44 which, from its operating position, moves away from the machine housing lower part 45 containing the other brush roller 12 into a housing -Open position (Fig. 6) can be transferred.
  • the upper part of the machine housing 44 can be pivoted up about an articulation axis 46 which is arranged on a housing side facing the brush roller end faces, ie the articulation axis 46 extends at right angles to the axial directions of the brush rollers.
  • the upper part 44 can be folded up further than shown in FIG. 6.
  • the housing In the open position, the housing is then open so that the hoses can be placed on the lower brush roller 12.
  • the hoses could also be inserted in such a way that they are inserted by hand through the hose inlet opening 7 and guided by hand between the brush rollers to the outlet opening 8. This procedure would not pose any particular difficulties either, since the individual rollers 20, 21 can dodge due to their pivotable mounting.
  • the drive contains those arranged on the machine housing upper part 44 and participating in its swiveling movement
  • Brush roller 11 which in the exemplary embodiment is formed by the two individual rollers 20, 21, by means of a drive gear arranged on the lower part 45 of the machine housing - this is the drive gear 40 already mentioned - and a follower gear arranged on the upper part 44 of the machine housing - these are here around the already mentioned follower gear 41 -, the two gears meshing in the operating position of the upper part 44 and being disengaged in the open position of the housing.
  • the drive gear 40 is thus fixed in position on the lower part 45 and the follower gear 41 is fixed in position on the upper part 44, both gears being located in the region of the dividing line between the lower part 45 and the upper part 44.
  • the follower gear 41 pivots away from the drive gear 40, so that the drive of the upper brush roller 11 is interrupted. If the upper part 44 is pivoted back into the operating position, the follower gear 41 comes into engagement with the drive gear 40 again.
  • the connecting line running in the operating position between the centers of the two gears 40, 41 and the direction of movement of the follower gear 41 when the upper part 44 is transferred from the open position to the operating position (this direction of movement is vertical in Fig. 2) are angular to each other.
  • the two gears 40.41 are not arranged exactly vertically one above the other. If the mentioned connecting line and the direction of movement of the follower gear would coincide, a tooth tip of the follower gear 41 could hit exactly one tooth tip of the drive gear 40 when closing the housing, which could result in damage.
  • the offset arrangement of the gearwheels shown in FIG. 2 ensures that no canting or jamming can occur. The follower gear turns automatically into the correct engagement position.
  • the interior of the washing machine which contains the brush rollers 10, 12 and in which the washing process takes place, is delimited at the bottom by a bottom plate 47 indicated in FIG. 2, which is provided with openings 48 for the outflow of the washing water.
  • This bottom plate 47 is located approximately at the level of the lower edge of the hose outlet opening 8. At the end of the washing process, when the rear hose coupling piece 6 emerges between the brush rollers, the bottom plate 47 forms a base for the coupling piece 6, which thus does not fall down in the washing machine housing can.
  • the bristle ring 24 of the brush roller 24 forms a side stop for the two hoses 1, 2 running through it on both sides.
  • guide walls 49, 50 which are arranged upstream of the brush roller end faces can also be present in the washing machine housing only in FIGS. 4 and 5 are indicated in a small section.
  • the pivot axis 33 faces the hose inlet opening 7 with respect to the individual rollers and is arranged above the individual rollers, so that the holding arms 29, 30, 31, 32 start from the Single rollers, extend obliquely upwards towards the inlet opening 7.
  • the belt drives 42, 43 assigned to the individual rollers extend along the holding arms.
  • the continuous brush roller 12 can sit on similar holding arms 12 which extend from the brush roller 12 to the inlet opening 7.
