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.

Abstract
Description
- 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.
- An installation of this type is disclosed in US-A-4 452 135. With this known installation the hose is conveyed over an endless conveyor belt on which a roller mechanism cap be held pressed down under spring loading. With this arrangement the hose is squeezed together between the conveyor belt and the roller mechanism. The water still contained in the hose is squeezed out by this means. A similar installation is disclosed in EP-A-0 360 603.
- 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. It is true that 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.
- With the installation according to the invention, as soon as a coupling arrives at one of the nips between two pinch elements said elements move apart. However, the hose is still held squeezed together at the location of the other nip and, consequently, no liquid can flow back.
- In particular, 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.
- As the hose is taken in further the pinch elements at the location of the other nip are moved apart to permit passage of the coupling. However, the nip which has already been closed again now provides the seal.
- The pinch elements can be constructed in various ways. Preferably, 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.
- The way in which the nip is adjusted to a coupling moving through it can also vary. In this context, for example, each pressure roller can be movable by means of its own drive. In this case, 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.
- According to a preferred embodiment 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.
- Furthermore, 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. With the aid of a supporting construction of this type, the installation can, for example, be mounted on a container in which the entire hose can be accommodated. By virtue of the fact that the supporting construction is rotatable, said construction is able to adapt to the passage of the hose as it is taken in by means of a vehicle driven past the hose.
- 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. In the working 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.
- To enable the installation to be used on both the left and the right of a vehicle, 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.

In this position,
pressure roller 15 has been swung away fromroller 8, so that thecoupling 4 can move through the wide nip now formed in this location. - Any water present in
hose section 2 outside the installation is, however, not able to flow intohose section 3 ashose section 2 is now held pressed flat betweenpressure roller 14 and associatedroller 7. As a result of the interaction betweenpressure roller 14 androller 7, any water present inhose section 2 is held back and, at the same time, the drive is maintained. - A
