Definitions

  • the invention relates to an installation for taking up a flexible hose for conveying liquid, such as a fire hose, comprising two pairs of turning pinch elements placed opposite one another, the pinch elements of each pair defining a nip of variable nip dimension, through which nips the hose can be transported in order to expel residual liquid therefrom, which variable nip dimension can be enlarged to permit the passage of a coupling present in the hose.
  • Hoses of this type are made up of sections which are provided with hose couplings at both ends.
  • the couplings are made of metal and therefore can not be compressed like the flexible material of the hose itself. Therefore at the moment the couplings have to pass, the roller mechanism moves away from the conveyor belt. Consequently, the water which has been squeezed out can flow back again.
  • a second roller mechanism is provided which, by means of a rocker, moves towards the belt as the first roller mechanism moves away from the belt. Nevertheless, in view of the time which elapses between the release of the pressure exerted by the first roller mechanism and the application of pressure by the second roller mechanism, a relatively large amount of water can still flow back again, especially if said water is under any pressure.
  • the quantities involved can be appreciable, especially if there are differences in height in the path taken by the hose. As a consequence of the removal of the driving force, the hose will also have a tendency to slide back under the weight of the water and the coupling.
  • the aim of the invention is, therefore, to provide an installation for taking up a hose which is also suitable for emptying under pressure and for transporting a hose assembled by means of couplings.
  • This aim is achieved in that of each pair, one pinch element is supported by means of its own swinging arm, each swinging arm being provided with adjustment means controlled by sensors for detection of a hose coupling, whereby the nip dimensions of the pairs are variable independently of one another, so that upon detection of a hose coupling the nip dimensions of each pair of pinch elements can be increased independently of one another by the adjustment means and the hose can continuously be held compressed by at least one of the nips.
  • the nips are located such a distance apart that the hose can be held compressed at the location of both nips if the coupling is located in the region between said nips.
  • the pinch elements can be constructed in various ways.
  • the pinch elements are constructed in the form of a roller body having a pliable surface, each pinch element together with another opposing pinch element defining a nip.
  • An associated pressure roller can be located against each roller body, which pressure roller can be moved towards or away from the roller body in order, respectively, to reduce or increase the size of the nip.
  • each pressure roller can be movable by means of its own drive.
  • sensors are also provided for detection of a hose coupling, as well as adjustment means for increasing and reducing the size of the nip when a hose coupling is detected.
  • each roller body is constructed in the form of a cylinder of pliable material which is closed at both ends and is pressurised internally, which cylinder can optionally be provided with a corrugated surface in order to increase friction.
  • a supporting construction can be provided on which the pinch elements are rotatably mounted, which supporting construction is rotatably supportable about a centre line which runs transversely to the centre line of the pinch elements.
  • the installation can, for example, be mounted on a container in which the entire hose can be accommodated.
  • Said supporting construction can be movable between a working position, in which, viewed in the direction of transport, the front pair of pinch elements are at a lower height than the rear pair of pinch elements, and a rest position.
  • the direction of transport is oriented sloping upwards, the hose taken in being able to assume a natural curve.
  • the rotary shaft of the supporting construction can be supported on a holder, which holder is movably guided in an essentially vertical guide path.
  • the desired trajectory can be obtained if the guide path is curved obliquely at its upper end and the holder on one side has a guide, such as a roller or slide block, with which it is guided in the guide path, and on the other side is supported by a cylinder jack.
  • the guide path and cylinder jack are mounted on a guide frame for moving them in the transverse direction.
  • the invention also relates to a method for taking up a fire hose into a loading bay in a vehicle by means of an installation as described above mounted on said loading bay, the supporting construction being located, viewed in the normal direction of travel, at the front of the loading bay, comprising driving the vehicle forwards past the fire hose, which has been laid out on the ground, and taking up the fire hose by means of the installation at a speed which essentially corresponds to the speed at which the vehicle is moving.
  • Figure 1 shows a partially exposed, perspective view of an installation according to the invention.
  • Figure 2 shows a side view of the installation according to Figure 1.
  • Figure 3 shows a lorry equipped with an installation according to the invention.
  • Figure 4 shows a side view of a second embodiment.
  • Figure 5 shows the view according to IV-IV.
  • FIGS 1 and 2 show an installation for taking up a flexible hose, which is indicated in its entirety by 1.
  • Said flexible hose comprises hose sections 2, 3, which are attached to one another by means of coupling 4.
  • the installation comprises a frame 5, provided with side plates 6 in which two pinch elements, constructed in the form of a roller body 7, 8 having a pliable surface, are rotatably mounted.
  • Said rollers can, for example, comprise a cylinder of pliable material 9, which at the ends is provided with an airtight connection to a rotary hub 10, the surface of which is provided with corrugations which increases friction.
  • Roller 7 is also drivable by means of motor 11; roller 9 is likewise drivable, via pulleys 12 and belt 13.
  • Each roller 7, 8 is provided with a pressure roller, 14 and 15 respectively.
  • Said pressure rollers are rotatably mounted on swinging arms 16, which are each rotatably mounted on bearings at 17.
  • the swinging arms 16, together with pressure rollers 14, 15, can be swung towards or away from the associated roller 7 or 8, respectively.
  • a pair of guide rollers 19, the purpose of which is to guide the hose 1 as it moves inwards, are also provided on the frame 5.
  • pressure roller 14 has been swung away from the associated roller 7, so that the coupling 4 can move through the wide nip thus formed.
  • Pressure roller 15 has been swung towards the associated roller 8 and holds the hose 1, in particular hose section 3, firmly squeezed in the narrow nip thus formed.
  • the hose will be fed through the installation in the direction indicated by arrows. Any water present in the hose will be held back by roller 8 and pressure roller 15, so that this water is forced to flow away through the other hose section 2.
  • a scraper element 80 is attached to the swinging arms 16 for scraping clean the upper side of the hose which has been pressed flat. There will also be a scraper element (not shown) for scraping clean the underside of the hose which has been pressed flat.
  • scraper roller (not shown) can also be provided. The latter rests with its surface against pressure roller 14, so that is moved in the opposite direction to the direction of movement of hose 2. Any small stones adhering to hose 2 can be reliably removed by means of a scraper roller of this type, which can be constructed in the form of a brush.
  • a corresponding scraper roller in this case driven by roller 7, can be mounted at the underside of the hose.
  • Sensors 20, 21 and 22 are present to ensure that the hydraulic piston cylinder devices 18, 19 are operated at the correct times. As soon as sensor 20 detects a coupling 4, a signal is transmitted to a control unit, which incidentally is not shown, as a result of which signal piston cylinder device 18 associated with pressure roller 14 is actuated and swings said roller away from associated roller 7.
  • the frame 5 is mounted on a vertical rotary shaft 23 in such a way that the entire installation can adjust itself to the trajectory of the incoming hose 1, controlled by the guide rollers 19.
  • the entire installation can be used on a lorry.
  • the vertical rotary shaft 23 is mounted at the front of a container 24 in which the hose 1 can be stored.
  • the lorry 25 is driven along the path followed by the hose 1, the installation being able to adjust itself to the trajectory of the incoming hose by virtue of the guide rollers 19.
  • the water is still expressed from the hose 1 as the latter is taken in, as described above with reference to Figures 1 and 2.
  • FIG 4 part of the container 24 corresponding to Figure 3 is shown.
  • the installation for taking up a hose has two roller bodies 7, 8 and two pressure rollers 14 and 15, respectively.
  • the positioning of the hinge points 51 and 52 and of the arms 53 and 54 on which said pressure rollers 14 and 15, respectively, are mounted differs somewhat from that according to Figure 2, although the mode of operation is identical.
  • the supporting construction in which said elements are accommodated and which is indicated in its entirety by 55 is rotatably mounted on the holder 57 by means of rotary shaft 56.
  • said holder 57 is supported in the guide path 59 by means of two coaxial rollers 58, only one of which is to be seen in the side view in Figure 4.
  • the holder 57 is supported by means of hinge 60 at the flange 61, which is welded to the housing 62 of the piston cylinder device 63.
  • the broken lines show the position of the piston cylinder device 63 when the piston is withdrawn.
  • roller 58 has rolled in the guide 59 such that the holder 57, and thus the entire supporting construction 55, has tilted.
  • the installation 50 is stored in compartment 64.
  • the piston rod 65 of the piston cylinder device 63 is fixed to section 66; the guide 59 is fixed to a section 67. Sections 66, 67 are connected to one another by means of brackets 68.
  • the framework formed by sections 66, 67 and brackets 68 is supported on one side on a rail 70 by means of rollers 69 and on the other side on a rail 72 by means of rollers 71.
  • the rollers 71 and the rail 72 can be seen in the top view shown in Figure 5.
  • the rails 70, 72 extend from the left to the right side of the compartment 64, in such a way that the installation can take in a hose to the left and the right of the lorry.
  • the continuous lines in Figure 5 show the location of the hinge pin 56 and holder 57 in the working position.
  • the supporting construction 55 has been omitted here.
  • the broken lines show the supporting construction 55 in the rest position, in which it is located entirely within the compartment 64.
  • Figure 5 also shows the cable 73, which on the one hand is wound with both ends on the discs 74, 75, which are mounted on a common shaft 76. Both discs can be driven in the same direction by means of the motor 77. On the other hand, cable 73 is passed over cable pulleys 78 and 79, and fixed to section 66. The fixing of cable 73 is shown in the side view in Figure 7.
  • the framework composed of sections 66 and 67 and brackets 68 can be moved backwards and forwards over the rails 70, 72 by means of motor 77 and cable 73.
