A cross-section of the decoiler or the reel is narrowed from a side that is facing the supporting element to a free end. The free end is provided as lying separated from the supporting element. One of the three poles (3,5,7) is arranged on the side portions (9,11). A tilt angle between a contour of the reel and the rotation axis of the reel is in a viewing direction facing perpendicular to the rotation axis of the reel between 0.5 degree and 5 degrees. An independent claim is included for a method for winding a hose.

Description

The invention relates to a hose reeling device, and more particularly to a hose reeling device which is suitable for use with hoses such as e.g. Pressure hoses or suction hoses of all popular diameters, which are used in particular by fire departments to wind in the form of a hose reel and thereby emptying.

For common firefighting tasks, such as firefighting, disaster relief, or disaster recovery, two different types of hoses are generally used. These are on the one hand so-called suction hoses for sucking water or other liquid, for example, to eliminate consequences of a flood disaster. On the other hand, there are so-called pressure hoses, which serve extinguishing agents, such. To direct water, a water-foam mixture, a CAFS foam or other liquids under pressure to a source of fire. While in the past, especially so-called B-, C- and D-hoses with diameters between 25 and 75 mm in different lengths were used, there is lately due to the larger diameter and thus to be achieved increase in performance for the use of so-called A hoses. A hoses have a diameter of 110 mm and are available in standard lengths of 5 or 20 m.

After an operation has been carried out, it is necessary to empty the hoses used on the one hand, that is, to remove remaining liquids in the hoses, and on the other hand to stow the hoses space-saving, so that they can be prepared for the next use.

The preparation of a hose includes, among other things, a cleaning of the hose, a tightness test of the hose and a drying of the hose. The latter can be particularly important, in particular Pressure hoses, inter alia, consist of a fiber fabric, which can lead to deterioration of the material during prolonged storage in a wet state. In order to use the hose in a future use without loss of time, this is combined in a special way in S-shaped bays and housed in a corresponding vehicle such as a hose car or other fire engine. Large fire departments such as professional fire brigades in larger cities usually have these preparation activities carried out by external service providers, while small fire brigades usually carry out these preparatory activities themselves.

At any rate, as a first step in the preparation, it is necessary to dewater and rewind the hoses used immediately after use. Since the weight of an A-hose with a standard length of 20 m is about 40 to 50 kg, these hoses are difficult for a single man when rolled up and almost impossible for a woman to handle. In particular, when lifting so wound up to hose reels and wet A-hoses of the spine apparatus of the firefighter can be excessively burdened, which sooner or later cause physical damage to the staff.

Currently, hoses of the following types are usually used in fire service applications: A hoses (Ø 110 mm), B hoses (Ø 75 mm), C hoses (Ø 42/52 mm), D hoses (Ø 25 mm), HP hoses (Ø 28 mm) and F-hoses (Ø 150 mm)

The document discloses the prior art US Pat. No. 7,661,683 B2 a hose carriage with a winding rod mounted on both sides, which is rotated by a motor in rotation to wind a hose. It is necessary for a user to push the cart along the laid and wound hose. During winding, the hose is passed over an elevated upstream and rotatable guide rod, so that any extinguishing water can flow out in the hose.

From the publication DE 10 2009 010 167 A1 is a winding device for fire hoses known, which consists of prefabricated, pluggable aluminum square tubes. These form a largely torsion-resistant frame. A turntable is driven by ball bearings via a hand crank and has a fork to accommodate B, C or D hoses.

It is the object of the invention to provide a Schlauchaufwicklungsvorrichtung and a - method, with which all the usual hoses can be emptied and wound up in the form of a hose reel after use, while reducing a physical stress on a user.

The object of the invention is achieved by a Schlauchaufwicklungsvorrichtung according to claim 1. Advantageous embodiments are set forth in the dependent claims. In addition, the object of the invention is achieved by a method according to claim 14.

A hose reeling device according to the invention has a reel rotatably mounted on a support element, whose cross-section decreases from a side facing the support element to a free end remote from the support element.

According to the invention, the reel is mounted on one side along its axis of rotation, and has a free end along its axis of rotation on its other side. In addition, the cross section decreases from the stored side along the axis of rotation to the free end.

The reduction in cross-section, for example, continuously in the form of a cone of a pyramid, a truncated cone or truncated pyramid or in a stepped manner. Thus, when viewed in a direction vertical to the axis of rotation of the reel, a contour of the reel is tapered toward the free end.

Since the cross section of the reel is reduced towards the free end, there is a hose wound on the reel and the reel itself only in the area of the side on which the reel is stored, a strong friction. This friction is sufficiently large to be able to wind the hose to a solid hose reel. Towards the free end, the friction between the hose and the reel becomes weaker or even disappears completely. Advantageously, it is therefore possible to deduct the hose reel after the completion of the winding with a relatively low frictional resistance and therefore also a small amount of force from the reel and supply.

The reel can be formed by means of three rods, which are arranged on the side facing the support element on a side part of the reel, and whose free ends are inclined to each other.

The three bar design advantageously allows a hose coupling to be suspended between two of the three bars, while the third bar ensures that the tube is wound in a substantially circular manner. That is, the innermost winding of the hose roll is formed substantially in the form of a circumference of the approximated triangle formed by the three rods. Therefore, the hose can be wound up in the form of a nearly circular hose reel, whereby it can be stowed to save space and compact.

At least one of the three rods can be adjustably arranged on the side part of the reel.

The adjustment of the rods makes it advantageous to adjust the reel for different hose sizes, or coupling sizes. Accordingly, it is possible to remove all hoses currently in use - i. A-hoses (Ø 110 mm), B-hoses (Ø 75 mm), C-hoses (Ø 42/52 mm), D-hoses (Ø 25 mm), HP hoses (Ø 28 mm) and F-hoses (Ø 150 mm) with one and the same hose rewinding device.

Advantageously, additionally or alternatively, at least one of the rods may taper towards its respective free end. Preferably all of them rejuvenate Rods towards their free end may be formed in a substantially conical shape.

An angle of inclination between the contour of the reel and the axis of rotation of the reel, when viewed with a line of sight substantially perpendicular to the axis of rotation between 0.5 ° and 5 °. The angle of inclination between the outermost edge line (e.g., tangent) or area of the respective bar and the axis of rotation of the capstan is defined.

Advantageously, the reel or the rods can be surface-treated or coated. This can be done, for example, mechanically by a fine grinding followed by a polishing, by a galvanic coating such as e.g. Chromium plating or by coating with a plastic, e.g. Polytetrafluoroethylene done. But it can also be pushed plastic tubes over the rods.

To assist the winding, a manually, electrically, pneumatically or hydraulically operable drive for the reel can be arranged on the support element.

Advantageously, a pneumatic drive can be provided in particular in the fire department, since a sufficient amount of compressed air is available both in corresponding compressed air reservoirs in the vehicles as well as in portable compressed air cylinders. Likewise, an electric drive is advantageously used. This can be characterized in particular by a compact size in conjunction with high performance. On the one hand rechargeable batteries can be used to drive an electric drive. On the other hand, an electric drive, e.g. can also be operated advantageously via a generator, which is driven for example via an existing internal combustion engine in a vehicle.

Particularly advantageously, a manual drive can also be combined with a pneumatic, electric or hydraulic drive, for example via a crank drive. This is possible for example via a freewheel. In this case For example, the first and last windings may be performed manually while the majority of the hose is wound by the pneumatic drive. It is noted that instead of the already mentioned drive types, other drives with the same effect, such as a direct drive via an internal combustion engine can be used.

According to the invention, a gap formed from at least two rolling bodies can also be provided on the supporting element. The axis of rotation of the two rolling bodies can advantageously lie parallel to a central axis of the reel. The gap may be designed to guide through this a hose to be coiled to the reel.

The arrangement with two rolling bodies on the one hand advantageously allows compression of the tube in a flat shape, which leads to an improved emptying of the hose. On the other hand, the hose can be dewatered by squeezing in the nip. Here it is particularly advantageous if the gap is arranged at a height well above the ground.

The rolling elements may be designed as cylindrical rollers which are arranged in a frame which is open at an end remote from the support element.

Due to the open frame, it is advantageously possible to introduce the hose between the two cylindrical rollers in the gap.

The frame may be arranged to actuate an actuator between a working position and an actuating position movable on the support member.

Hoses intended for use with the hose reeling device according to the invention usually have a hose coupling at both ends thereof. However, this can not be performed by the gap formed between the two cylindrical rollers due to their dimensions. There is therefore a movement of the frame as soon as the hose coupling at the distal end of the hose against the cylindrical rollers in Attachment device. Since due to the rotating reel still a tensile force acts on the hose coupling, the movable frame is moved and actuated by the movement of the frame an actuator.

The terms distal and proximal as used in this specification with reference to the hose ends refer to the position of the respective hose end to the reel of the hose reeling device. Thus, the proximal end of the tube is the end at which the winding of the tube is begun, while the distal end is that end which is moved into the area of the reel until the end of the winding process.

Advantageously, the movement of the frame in the actuated position actuate the actuator, whereby a shutdown of a drive of the reel is effected. The drive of the reel mentioned here may be one of the aforementioned drives or an alternative drive. It should also be noted that the movement of the frame can not only be achieved by the hose coupling engaging with the cylindrical rollers, but that the frame can also be moved if the hose can not be smoothly passed through the gap, for example tangled or knotted.

According to the invention, a hose guide can additionally be arranged on the support element. The hose guide is designed in such a way that a hose to be wound up is guided over it to the reel. The hose can run both above the guide as well as below the guide.

Advantageously, the hose guide can be adapted to a width of the hose to be wound up.

The support member may be made in one or more parts and in particular be part of a frame or a housing of the Schlauchaufwicklungsvorrichtung.

A first embodiment of the invention will be described with reference to FIG FIGS. 1 to 5 described.

A Schlauchaufwicklungsvorrichtung has a housing 1, in which a pneumatic, an electric or a hydraulic drive is housed. On a reel-side wall 4 of the housing 1, a reel disc 9 is mounted such that it can be rotated by the drive. On the reel disk there is a T-shaped projection, which is referred to below as the guide 11. On the guide 11 three rods 3, 5, 7 are mounted by means of releasable jaws 3a, 5a, 7a. By loosening one of the jaws 3a, 5a, 7a, the corresponding rod 3, 5, 7 along the T-shaped projection of the guide 11 can be moved.

The three rods 3, 5, 7 are only at one end on the jaws 3a, 5a and 7a, which serve as an adjustable support attached to the reel disc 9, while the other end of the rods 3, 5, 7 as a free end (unsupported) is executed. The three rods 3, 5, 7 are each formed in a substantially conical shape with a preferred cone angle of 1 °. As a result, the contour edges of the reel, when viewed with a viewing direction substantially perpendicular to the axis of rotation of the reel, are at an angle to the axis of rotation which is essentially perpendicular to the reel disc 9. This reduces a cross section of a reel formed by the reel disc 9 and the rods 3, 5, 7 reel to the free end.

The cross section of the reel is defined as the area that would normally be created by the reel on the axis of rotation. Correspondingly, the cross section of the reel corresponds to the triangular surface which is perpendicular to the axis of rotation and whose corner points are essentially formed by the three rods 3, 5, 7.

By loosening the clamping jaws 3a, 5a, 7a secured by screws, the three rods 3, 5 and 7 can be adapted to the dimensions of a hose coupling or a hose which is to be wound up. This is particularly advantageous because hoses of different diameters are usually used in a fire service operation. The diameters of the hoses can be between 25 mm for D hoses and 150 mm for F hoses. For standard applications, A, B and C hoses with diameters of 110 mm, 75 mm and 42/52 mm are mainly used.

On the housing 1 is also a hose guide 17, in the form of a perpendicular to a reel-side housing wall 4 arranged rod with two pins 18 and 19. While the pin 18 is fixed, the pin 19 serves as an adjustable setting pin to the width of the hose guide to adjust the width of a hose to be wound.

In addition, on the reel-side housing wall 4 via an arm 27, a roller assembly consisting of two cylindrical rollers 21, 23 is mounted in an open roller frame 25. Since the frame 25 is open, it is possible to insert the hose to be wound in a gap formed between the two rollers 21 and 23.

On the roll frame 25 is also a gap receiving guide 29, which is formed by means of a rounded planar element and two pins serving for the lateral boundary.

The arm 27 is rotatably attached to the housing 1 about a pivot point 28 and is connected by a suitable means such as e.g. biasing a biasing spring, not shown, into a working position shown in the figures. By a rotation of the arm 27 about its pivot point 28, a recorded in the housing 1 actuating element is triggered, which is carried out by means of a limit switch. When the actuator is triggered, the drive of the reel is switched off.

The rotational movement of the arm is, for example, brought about when a hose coupling at the distal end of the hose to be wound against the gap receiving guide 29 or against one of the two rollers 21, 23 in Appendix. Since the hose coupling can not pass the gap formed between the two rollers 21, 23, the frame 25 is rotated about the pivot point with the arm 27 by the pulling force acting on the hose, whereby the actuating element is triggered.

In addition, a switch 13 is still provided on the housing 1, which serves for switching on and off of the drive. How out Fig. 3 to 6 it can be seen, is located on a side remote from the reel-side wall 4 wall of the housing 1, a hand crank 35, with which the reel can be additionally operated manually via a freewheel. The crank axis of the hand crank 35 is aligned with the axis of rotation of the reel. A terminal 34 is provided on the housing to supply the drive in the housing 1. Accordingly, compressed air is supplied via the connection 34 in the case of a pneumatic drive and, in the case of an electric drive, power is supplied.

To wind a hose, the hose reeling device is placed on a transport box 31. To wind a tube, a proximal coupling, ie a coupling at the end of the tube at which the winding process is started, is between two of the three rods 3, 5, 7 hooked. This is preferably done by the coupling between the two rods 3, 5, 7 is guided so that the tube is between the two rods 5 and 7. If the adjustment of the three rods 3, 5, 7 does not correspond to the size of the coupling or hose, it can be changed beforehand.

The tube leading away from the proximal coupling is inserted into the tube guide 17 set to the tube width and into the gap formed between the two rollers 21, 23. Thereafter, an operator 33 actuates the switch 13, whereby the drive of the reel begins to rotate it. The wound hose is then pulled over the gap receiving guide 29, through the gap between the rollers 21, 23, over the hose guide 17 to the reel and wound up on the hose reel formed there. Since the hose is located between the two rods 5 and 7, and due to the construction of the coupling can not bend directly in the region of the two rods 5 and 7 form the end located in the hose of the coupling with the three rods 3, 5 and 7 four circumferential points of a circle around which the tube is wound substantially circular.

When the tube is almost completely wound up, the distal coupling of the tube, i.e., the coupling at the second, distal end of the tube, abuts against the gap receiving guide 29, the frame 25, or one or both of the rollers 21,23. In this state, the tensile force of the attached to the arm 27 frame 25 is rotated about the pivot point 28 while the recorded in the housing 1 actuating element activated. This leads to the immediate shutdown of the drive of the reel.

The remaining short piece of tubing is then removed from the gap between the rollers 21, 23 and the tube guide 17 and wound up by operating the hand crank 35. Thereafter, the resulting hose roll by the operator 33 can be easily removed from the reel. Pulling off the hose reel is therefore simplified because the cross section of the reel decreases towards the free end. For this reason, it comes only to a relatively low friction between the rods 3, 5, 7 of the reel and the hose, which decreases all the more, the farther the hose reel is pulled towards the free end. In addition, since the hose reeling device is stored on a frame 15 of the transport box 31, it is no longer necessary to lift the hose reel, but it can be easily dropped into the box.

The embodiment of the reel with the three rods 3, 5, 7 also makes it possible, prior to removal of the hose reel, to provide a safety device, e.g. a backup tape or hose carrier to attach a portion of the hose reel. For this purpose, e.g. the safety band or hose carrier between the reel disc 9, the rod 3 and one of the other two rods pushed through, and wound around the corresponding hose portion to prevent unintentional unwinding of the hose reel.

To fill the box with several hose reels, the above-described process is repeated according to the number of hoses to be wound up. In this case, the Schlauchaufwicklungsvorrichtung can be moved on the frame 15 of the transport box 31 to stow the respective hose reels at corresponding positions in the transport box 31. Once the crate is full or all hoses are rewound, the hose rewinder is lifted from the crate and reused on another crate or stowed in an appropriate vehicle.

Incidentally, a side wall of the transport box 31 can be folded down, whereby the unloading of the stowed in the box hose rolls is facilitated.

Fig. 6 shows a variant of the first embodiment, which differs by the shape of the rods and their orientation. Identical and functionally identical elements, already based on Fig. 1 to 5 have been described, the same reference numerals as in Fig. 1 to 5 and will not be described again.

According to the variant in Fig. 6 are three rods 53, 55, 57 also attached to the reel disc 9 only at one end via the jaws 3a, 5a and 7a, which serve as an adjustable holder, while the other end of the Rods 53, 55, 57 is designed as a free end (unsupported). The three rods 53, 55, 57 have a substantially cylindrical shape and are arranged obliquely to the rotational axis lying substantially perpendicular to the reel disc. Therefore, a normal distance between each two of the three rods 53, 55, 57 decreases between the attached to the reel disc 9 ends to the free ends. Namely, the rods 53, 55, 57 are obliquely attached to the reel disc 9 in such a manner that their free ends are inclined to each other. This reduces a cross section of a reel formed by the reel disc 9 and the rods 53, 55, 57 reel to the free end.

Fig. 7 to 9 show a second embodiment of the invention. According to the second embodiment, the hose reeling device is on a carriage. Since the hose reeling device has substantially the same or equivalent components as the hose reeling device of the first embodiment, a repetition of the description of those elements having the same reference numerals will be omitted.

According to the second embodiment, the hose reeling device is accommodated on a carriage floor 41. However, the hose take-up device occupies only a small part of the area of the carriage floor 41. The car also has a on a narrow side a carriage frame 47 with a cross bar 49. On the carriage frame 47 is also a handle 43. Not shown compressed air cylinders can either be accommodated lying on the car floor 41, or hooked by means of a suspension device on the crossbar 49 to compressed air as a drive means for the pneumatic drive of the reel in the housing 1 deliver.

The carriage also has individually suspended wheels 45. The wheels have a diameter and a thickness, which make it possible to push the car in an exposed area such as a swampy meadow and overcome small bumps. The wheels are also rotatable about a vertical axis to facilitate steering of the carriage. To prevent rotation about the vertical axis, each wheel can be detected. Besides, they are provided on at least two wheels brakes to prevent unintentional rolling of the car.

It should also be noted that, in contrast to the first embodiment, there is a marked difference in height between the roller frame 25 arranged near the bottom and the hose guide 17. The fact that the hose to be wound increases relatively steeply to the hose guide 17 after the gap formed between the two rollers 21, 23, results in a reliable emptying of residual water or other liquid in the hose.

The operation of the hose reeling device of the second embodiment is otherwise substantially similar to that of the hose reeling device of the first embodiment. However, the wound-up tube rolls are stored instead of in a transport box 31 on the car floor 41. Depending on the diameter of the respective hoses can be stored in about four to five hose reels on the car floor.

The invention has been described with reference to the presently preferred embodiments. However, additional or alternative to the described embodiments, the following variants are possible.

Instead of forming the reel in the form of three rods, this can be made for example in the form of a truncated cone or truncated pyramid from the solid. To accommodate the hose coupling a T-shaped groove is then provided in the truncated cone or truncated pyramid.

The guide 11 may have markings corresponding to the sizes of the known standard hoses (A to F, HD) to facilitate adjustment for the corresponding hose size. The hose guide 17 may also have corresponding markings to move the adjusting pin 19 according to the respective hose width.

The hose reeling device according to the second embodiment may have a second output shaft connected to a counterpart on the carriage can be coupled to power this. In particular, it may be possible to switch the drive either on the reel or on the car.

By using an extension from the port 34 or by providing a remote control and a corresponding receiver on the hose reeling device, it is possible to operate the hose reeling device at exposed positions which for safety reasons must not be entered by the operator 33. For example, it is conceivable to load the transport box 31 out of or into a transport vehicle by means of a forklift or another industrial vehicle. For example, since it is not allowed to stand on the forks of a forklift, the remote controller 39 enables time-saving operation of the hose reeling apparatus. Fig. 7 also shows two compressed air bottles 37, which serve to supply the pneumatic drive.

If an electric drive is used as drive, accumulators can be arranged as a power accumulator in the housing 1. During or after operation, these accumulators can be recharged via charging cable or the like attached to the terminal 34. In addition, the use of accumulators ensures a deep center of gravity of the carriage, which is particularly important when winding up larger diameter hoses, e.g. A-hoses is beneficial.

Alternatively or additionally, the electric drive can be powered directly via a generator in particular on one of the vehicles or via the electrical system of one of the vehicles and thus in the end by an internal combustion engine installed in the vehicle and a line 34 attached to the connection.

The use of a pneumatic drive, in particular in combination with the hand crank 35, is particularly advantageous because in the fire department compressed air in almost unlimited quantities is available both in storage in the vehicles as well as in portable compressed air cylinders.

The car floor may e.g. be made permeable by a perforated plate or a grid plate so that residual water can drain from the hoses.

As another drive form, it is possible to connect the reel to a vehicle via a propeller shaft or the like and thereby drive it.

While the invention has been described by the example of fire services as emergency organizations, it is pointed out that other public, state or private organizations, in particular in disaster relief service such. the technical relief organization or similar organizations as well as private users can use Schlauchaufwicklungsvorrichtungen according to the invention.

The above-described embodiments are presently preferred variants of the embodiment of the invention, but are not intended to limit the scope of the invention. The scope of the invention is defined by the appended claims.
