    Description [0001] Hose laying device for laying a hose and vehicle with hose laying device. Technical Field The present invention relates to a hose laying apparatus for laying a hose and a vehicle having the hose laying apparatus for laying a hose.
    A hose-laying device can be used, for example, in the fire department and is particularly helpful where long hose lengths are needed to supply water, for example in rural areas. In general, the hose section consists of individual hoses, which are interconnected by means of hose couplings.
    PRIOR ART [0004] DE 10 2005 056 003 A1 discloses a hose laying device. There, the hoses are initially in a flattened, folded state and preferably already connected to each other via couplings on a hose transport vehicle in a hose bay. In the case of a hose start fixed to a fly-by crane or an extinguishing water pump, a hose route can be laid by moving the vehicle forward. At the rear of the vehicle, a longitudinal strut is attached, which has a hose pointing point at its free end. To stabilize the longitudinal strut, a diagonal strut is attached to the rear. The longitudinal strut and the diagonal strut form a triangle in plan view. The tubing bay is open to the rear, so that the tubing can be pulled out of the tubing bay from there via the tubing extension point. However, this solution has disadvantages. First, it is time consuming when first the longitudinal strut and the diagonal strut must be mounted at the rear of the vehicle before the hose can be pulled out of the hose bay. If, instead, the longitudinal strut and the diagonal strut are permanently mounted on the rear of the vehicle, the installation effort is eliminated, but the vehicle then requires more space. A further disadvantage is that the hose, which is pulled out of the hose bay during laying, and in particular the hose couplings, can wobble back and forth, which can become a considerable danger to persons who are in the rear area of the vehicle, especially at higher vehicle speeds.
    Summary of the Invention An object of the invention is to provide a hose laying apparatus for laying a hose that is quick, easy and safe to operate.
    Advantageously, the hose laying device for laying a hose is also easy to use.
    The object is achieved by a hose laying device for laying a hose having the features specified in claim 1.
    The hose laying device according to the invention for laying a hose comprises a hose box for storing the hose and a laying arm with a hose leadthrough, wherein the hose can be passed through the hose leadthrough and the hose lead-through serves to guide the hose. In addition, an apron is provided, which is arranged between the hose box and the hose leadthrough.
    Advantageous developments of the invention will become apparent from the features indicated in the dependent claims.
    In one embodiment of the inventive hose laying device, the apron is designed as a tarpaulin, Blache, cloth or net. Such a trained skirt has the advantage that it is flexible and adapts easily to the position of the laying arm.
    In a further embodiment of the inventive hose laying device, the skirt is elastic. As a result, it can adapt to the position of the laying arm and can absorb part of the kinetic energy of the hose and in particular of the hose coupling. In particular, the dangling, which perform the hose and the hose coupling during rapid withdrawal from the hose box, can be effectively absorbed or reduced by the elastic apron.
    In an additional embodiment of the inventive hose laying device, the skirt is fastened by means of a welt on the hose leadthrough. As a result, the skirt can be connected in a form-fitting manner to the hose leadthrough in a simple and fast manner. Such a connection between skirt and hose passage is stable enough to absorb the partially high forces that are generated by the dangling of the hose and the hose coupling and acting on the skirt.
    In a further development of the inventive hose laying device of the laying arm is formed telescopic. This has the advantage that the length of the laying arm can be adapted to the respective needs and the laying arm in the retracted state saves space.
    In another embodiment of the inventive hose laying device, a pivot bearing is provided, on which the laying arm is attached. Thus, the laying arm can be easily pivoted to the desired position.
    In an additional development of the inventive hose laying device, the hose passage is formed as a ring.
    It is also possible to form the hose passage in the inventive hose laying device as a funnel.
    The hose leadthrough can be funnel-shaped on both the inlet side and the outlet side in the hose laying device according to the invention. That is, the two sides of the passage opening of the hose passage may be funnel-shaped.
    In addition, it is possible to provide a holder in the inventive hose laying device on the laying arm or on the hose leadthrough. The bracket may be configured to hold a hose coupling of the hose. The holder can also be designed so that it is suitable for holding various hose couplings. During the supply and removal of the hose laying device, the free end of the hose with the hose coupling is held in the holder, so that the hose coupling is secured and can not accidentally fall from the vehicle.
    Advantageously, the hose box in the inventive hose laying device on a first door and a second door. The two doors can be located at the back of the hose box. It ensures easy access to the hose box.
    In one embodiment of the hose laying device according to the invention, a further hose leadthrough for guiding a further hose is provided on the laying arm. This embodiment has the advantage that two tubes can be laid simultaneously. In addition, the two hoses can be laid directly next to each other automatically.
    In addition, a vehicle may be provided which has the above-mentioned hose laying device. As a result, the hose laying device becomes mobile.
    The vehicle may be designed as a trailer or as a transport vehicle. Obviously, if the hose laying device is mounted on a transport vehicle, no separate towing vehicle is required for the hose laying device.
    The inventive hose laying device may preferably be used for laying a fire hose.
    BRIEF DESCRIPTION OF THE DRAWINGS In the following, the invention will be explained in more detail with reference to seven figures.

    Fig. 5 shows the first embodiment of the inventive hose laying device in the side view with swung-away laying arm and hose.
    FIG. 6 shows the first embodiment of the hose laying device according to the invention in a three-dimensional view with the laying arm and apron swung out to the right.
    FIG. 7 shows a second possible embodiment of the hose laying device according to the invention in a three-dimensional view with two hose boxes and two hose passages on the laying arm.
    Modes for carrying out the invention The hose laying device 1 according to the invention can be mounted on almost any vehicle. The vehicle may be, for example, a transport vehicle. This is not mandatory. Instead, the vehicle may also be a trailer 2 as shown in the figures. As a result, the hose laying device 1 becomes mobile.
    A first possible embodiment of the inventive hose laying device 1 is shown in Fig. 1 in the side view. Fig. 2 shows the first embodiment of the hose laying device 1 from the same perspective, but with a swiveled and telescoped laying arm 14, 15. The hose laying device 1 can be constructed so that it can be charged as a unit or module on the trailer 2. This has the advantage that the trailer can also be used for other purposes.
    But it is also possible to mount the hose laying device 1 stationary on the trailer 2, so that the trailer 2 and the hose laying device 1 form a unit. Such a vehicle has the advantage that it is lighter overall than the variant in which the hose-laying device 1 can be loaded as a module on a separate trailer 2. This vehicle (unit of trailer and hose-laying device) can be designed so that, with a gross vehicle weight of 3500 kg, it has a curb weight of only around 900 kg. This allows the vehicle to transport around 2600 kg payload in the form of hoses, sections and other material. Assuming a hose weight of 450 kg per 1000 m, approximately 5000 m hoses can be transported and laid with the vehicle.
    The trailer 2 shown in the figures has a drawbar 2.4 usual for trailers, a trailer hitch 2.5 and a bridge 7. These components can be adapted to the respective requirements. Of course, this also applies to the number of axles and wheels 5 and 6.
    The hose laying device 1 comprises a hose box 8, in which one or more hoses can be stored. The hose box 8 has a front wall 2.1, a left side wall 9, a right side wall 22 and rear two doors 11 and 12. The left side wall 9 is divided into three parts in the embodiment shown in the figures. The front portion of the side wall 9 is formed as a rigid side wall 9.2 and the rear portion also as a rigid side wall 9.3. The middle section of the side wall 9 comprises a displaceable side wall 9.1 and a lower side wall 9.4. The sliding side wall 9.1 is formed so that it can be moved vertically. When the slidable side wall 9.1 is pushed down so that it is congruent with the lower side wall 9.4, as shown in Fig. 4, the interior of the hose box 8 is accessible to the staff of the base 2.7 from. The vertical movement of the side wall 9.1 has the advantage that it does not restrict the range of motion of the staff on the floor space 2.7. So that the staff can move the side wall 9.1 easier, a gas spring may be provided. For this purpose, the gas pressure spring can be fastened on the one hand to the movable side wall 9.1 and on the other hand, for example, to an immovable part of the side wall 9.2, 9.3 or 9.4.
    Instead of making the side wall 9.1 displaceable, it could also be designed so that it can be swung up or down. This can be achieved for example with appropriate fittings, which are designed as a Hubbeschlag, as swivel fitting or as a hub-swing fitting as needed.
    The side wall 9 opposite side wall 22 may be formed as a rigid side wall. But it is also possible to provide a movable wall portion in the side wall 22, so that from there the interior of the hose box 8 is accessible.
    About the rear of the hose box 8 arranged two doors 11 and 12 of the hose box 8 is also accessible. The doors 11 and 12 may be dimensioned and designed so that - even if the two doors 11 and 12 are closed-between the two doors 11 and 12, a gap 23 exists. The gap 23 is just so wide that the tube 20 can be guided through it.
    Also rear of the hose box 8 may be a drive with a roller 10 if necessary. The drive with the roller 10 can be mounted on an axis 10.1 on a yoke 24 above the doors 11,12.
    The size of the hose box 8 depends on the length of the hose 20, which should find space in it. The hose 20 may be, for example, a fire hose. The hose coupling 21 may be, for example, a so-called Storz clutch.
    Preferably, in the rear, lower region of the hose laying device 1 is a laying arm. This can be designed to be telescopic. The laying arm can, for example, have a first tubular laying arm 14, which is movably mounted in a second, slightly larger tubular laying arm 15. At the end of the tubular laying arm 14 is a hose feedthrough 13. The hose feedthrough 13 can be annular, as shown in FIGS. 1 to 7. However, the hose lead-through 13 may also have the shape of a trumpet or a funnel. In addition, it is possible to form the hose leadthrough 13 on both sides of its passage trumpet-shaped or funnel-shaped. Advantageously, the hose lead-through 13 is formed on both sides so that it forms a good, low-friction and especially safe guidance for the hose 20 and the hose coupling 21, and neither the hose 20 nor the hose coupling 21 are damaged when passing through the Hose passage 13 are pulled through. This applies both to the laying and to the retrieval of the hose.
    The opening width D of the passage opening of the hose leadthrough 13 can be adapted to different hose diameters or to different coupling diameters. If, for example, a hose with a nominal diameter of 110 mm (110 mm hose) is used, the hose laying device 1 can have a hose lead-through 13 with a larger opening width D than if only hoses with a nominal diameter of 75 mm (75 mm hose) are used.
    The pivot bearing 16 is preferably formed so that the laying arm 14, 15 attached thereto can be locked in different pivoting positions. For transport, it is helpful, for example, when the laying arm 14, 15 can be pivoted on the left or right side of the bumper of the trailer 2 and fixed in this pivoting position. Also for laying and for retrieving the tube 20, it is helpful to be able to lock the laying arm 14, 15 in a specific pivoting positions.
    In the following, the operation of the hose laying device 1 will be further explained.
    When it is referred to in the following of hose, so it is not only a one-piece hose, but also the case meant that several individual hoses are connected together to form a single, longer hose (a longer hose).
    In principle, a distinction is made between transport, laying operation and hose return operation.
    During transport, the hose 20 is in the hose box 8. The doors 11 and 12 are closed. Only a relatively short section of the hose 20 protrudes through the gap 23 between the two doors 11 and 12 out of the hose box 8 and is guided through the hose lead-through 13. The hose coupling located at the end of the hose 21 is held by the transport holder 19, which will also be referred to below as the holder in the following. This ensures that the entire hose is neatly and safely stowed during take-off and take-off. In addition, the hose end with the hose coupling 21 is already positioned so that it can be found immediately when needed and is at hand.
    If the hose-laying device 1 is located at the place of use, it is possible to start with the laying operation. For this purpose, the two doors 11 and 12 are first opened by means of the handle with integrated quick release 12.1. The laying arm 14,15 is pivoted in the desired direction, pulled out to the desired length and locked. For example, if the hose 20 is to be laid on the right-hand edge of the road, the laying arm 14, 15 will pivot to the right and then lock the pivot bearing 16 in this pivotal position. Subsequently, the hose coupling 21 is released from the transport bracket 19 and the hose laying device 1 is ready for laying the hose. As soon as the towing vehicle moves the trailer 2 with the hose laying device 1, the hose 20 is pulled out of the hose box 8 through the hose feedthrough 13 and deposited at that position which is predetermined by the position of the laying arm 14, 15.
    When the use is completed, the tube 20 can be stowed in the hose box 8 in the so-called hose return operation. For this purpose, the trailer 2 is positioned with the hose laying device 1 in the region of the one hose end and the laying arm 14, 15 brought into position. Subsequently, this end of the hose is first pulled manually through the hose lead-through 13 and then over the roller 10 into the hose box 8. This is illustrated in FIG. 5. Once the hose end has been pulled over the roller 10, the hose 20 can be automatically pulled over the roller drive 10 into the hose box 8. The transport vehicle pulls the hose-laying device 1 now along the still laid hose while the hose is automatically placed over the roller 10 in the hose box 8. To monitor this return process, a person can stand on the bridge 7 or on the floor space 2.7 of the trailer 2 and intervene if necessary.
    Fig. 6 shows the first embodiment hose laying device 1 obliquely from behind, now also the skirt 25, 26 can be seen. The skirt comprises a right apron portion 25 which is connected on the one hand to the door 12 and on the other hand to the hose lead-through 13. The apron also includes a left apron portion 26 which is connected on the one hand to the door 11 and on the other hand to the hose leadthrough 13. The two skirt sections 25 and 26 can each be fastened by means of a welt 26.3 to the hose lead-through 13. The connections between the doors 11 and 12 and the two apron sections 25 and 26 can be accomplished by means of piping.
    The skirt portions 25 and 26 may be interconnected at the bottom so that the skirt is partially or completely closed at the bottom. At the top, the skirt 25, 26 can be open. The skirt portions 25 and 26 may each be provided with one or more elastics 26.1 and 26.2 or other elastic means. The apron 25, 26 may be made of a tarpaulin, a sheet, a cloth or a net. Their purpose is to intercept the rapid movements of the hose from the hose box 8, the rolling movements of the hose 20 and the hose couplings 21 and protect people who are in the vicinity of the hose laying device 1. In particular, the dangling, which perform the hose 20 and the hose couplings 21 during rapid withdrawal from the hose box 8, can be effectively absorbed or reduced by an elastic design of the skirt. Due to the elastic training, the kinetic energy inherent in the rolling motion is degraded in a way that protects the material.
    In Fig. 7, a second possible embodiment of the inventive hose-laying device 1 is shown in a three-dimensional view obliquely from behind. In this embodiment, the hose laying device 1, two hose boxes 8 and 80, which are separated by a partition 33 from each other. The hose boxes 8 and 80 are accessible to the staff via the stand areas 2.7 and 2.8, respectively. In addition, the hose laying device 1 on the laying arm 14, 15 has two hose passages 13 and 130. This embodiment has the advantage that two tubes can be laid simultaneously. In addition, the two hoses can be laid directly next to each other automatically. Also in the return mode, two hoses can be brought back simultaneously into the two hose boxes 8 and 80. The hose-laying device 1 has for this purpose a second roller 50 which, like the roller 10, can be driven by means of a motor. The transport, the laying operation and the hose return operation function analogously in the second embodiment in the same manner as in the first embodiment. In order to avoid repetition, reference is made in this regard to the description of the first embodiment.
    On the bridge 7, one or more railings 17 and 18 may be mounted, which serve primarily the maintenance and security of the staff. In addition, one or more boxes 30 and 31 can be mounted on the trailer 2, in which, for example, accessories can be stored.
    The foregoing description of the embodiments according to the present invention is for illustrative purposes only. Various changes and modifications are possible within the scope of the invention. Thus, for example, the various components of the hose laying device 1 shown in FIGS. 1 to 7 can also be combined with one another in a different way than shown in the figures.
