Description

The The invention relates to a device for checking a hose, in particular a fire hose, accordingly the preamble of claim 1.

According to relevant Regulations need to fire hoses regularly checked for damage and leaks become. This is done by means of a pressure test in which Pressurized water is fed into the hose, causing damage and associated leaks are recognizable.

to Pressure test are known as tubing tubs, the the inclusion of a fully or halfway designed Serve hose. However, there is a risk that at a quite possible bursting of the hose during the pressure test personnel employed by it endangered is.

Besides is the handling of this device or their accommodation and Installation alone due to the length of the tub (with stretched hose 22 m and in half laid out 12 m) problematic, because above all construction conditions created must be in order to accommodate such tubing tubs.

To achieve a more compact design and to prevent operator endangering when the hose burst, it is out of the DE 44 13 273 C1 as well as from the DE 199 16 976 A1 known to wind the hose and subjected in a housing of a pressure test.

In this case, the hose according to the in the DE 44 13 273 C1 described method for pressure test spirally wound on a reel and then, after the examination, stored by means of an arranged outside the housing unwinding device. A washing unit is also installed outside the housing in front of the pressure tester.

All in all are the known devices, in particular with regard to a simple and largely automatic sequence of necessary work steps not suitable to meet the requirements.

Of the Invention is based on the object, a device of the generic type Type to develop so that a largely automatic washing, checking and winding the tube is possible.

These The object is achieved by a device having the features of the claim 1 solved.

These constructive design of the device brings a whole bunch of advantages over such a state of the art Technology with you.

So Let's first of all mention that this device is extremely Compact design, so with little space required, can be produced, where the two reels also in a common housing are installed, such as the washing and drying device as well the winding station.

To A preferred embodiment of the invention is provided, the two reels with low inclination, for example about 10 to To arrange 15 ° upright, resulting in a very narrow Dimensional results. In principle, the reels are also in horizontal position, so lying operable.

The Washing and drying unit is immediately before the first reel arranged and positioned or modified so that the hose from an assigned, preferably movable Vorwaschbehälter taken and when passing through the washing and drying unit the first reel is supplied.

For this is just one of the two existing hose connections to hang the hose in a tractor trailer a guide rail is movably mounted and with the the hose through the washing device and subsequent Drying unit is moved to a pressurized water connection.

is the hose connected to the pressurized water connection turns the reel under winding of the hose and simultaneous passage through the washing and drying unit.

The Drying takes place via vacuum suction nozzles, which are arranged downstream of the washing unit. During winding up the hose on the reel takes its automatic length measurement.

After a complete passage of the hose through the washing and drying unit, the exposed second hose connection is pressure-tightly connected to the pressure water connection of the second reel. Thereafter, an opposite to the first reel drive of the second reel takes place, wherein the tube is about half of the first reel again unrolled. Of course, the first reel rotates in the same direction as the second reel. The exact, so half The rolling distance of the hose is specified by means of a control with which the hose length was previously determined.

in the Subsequently, water is pressed into the hose by means of a pressure pump and this is checked for leaks and damage. The test pressure is about 16 bar.

After that The water is removed by means of drainage valves that automatically be opened, drained from the tube and into one Reservoir returned, wherein the water level via a level monitoring and a control electronics and a filling valve regulated becomes.

In front the filling of the hose with pressurized water or after the emptying comes a winding station for engagement, the two winding pins has, which are arranged at a distance from each other and run transversely to the longitudinal extent of the hose.

Between These winding pins, the hose is inserted, with the winding pins attached to a base plate, which in turn by a drive unit is rotationally drivable.

The entire winding station, so the drive unit with the with the Winding pins stocked base plate, is on a sled mounted reciprocally transversely to the longitudinal extent of the hose, so that the winding pins the hose by appropriate procedure of the sled can take up between themselves.

The Winding station thus attacks the middle of the hose. By rotation the base plate is due to the eccentric arrangement the winding pins of the hose pulled off both reels at the same time and rolled up, with complete emptying of the hose by squeezing the residual water. In this rolling up the both reels turned in opposite directions, so in full by the reels unrolled and rolled up on the winding station position the two hose connections are next to each other. D. h., In principle, the hose is rolled up double-layered and can be removed and stored.

The Housing of all relevant components, so the two reels, the Wrapping station, the washing and drying unit, the water tank with connected pressure pump and the drive units for the reels and the winding station is advantageously carried out so that they are at least on the front, ie from the operating side, is transparent, for which a suitable material is used, preferably acrylic or safety glass.

Furthermore if the housing can be closed by sliding doors, which are connected to a controller such that operation of the Device, in particular the pressure test, only with closed doors is possible.

Further advantageous embodiments of the invention are in the subclaims characterized.

One Embodiment of the invention will be described below of the accompanying drawings.

It each show in a schematic representation:

1 a device according to the invention in a front view

2 the device in a side view

3 the device in a rear view.

In the figures, a device for checking a hose, in particular a fire hose is shown, with a washing unit 3 , a downstream drying unit, consisting of two opposing suction nozzles 4 , between which the washed tube is guided, a pressure test device with which a fluid medium, preferably water, under pressure in the tube is conveyed, and a winding station 16 with which the cleaned and tested hose is wound ready for storage.

The Druckprüfeinrichtung has two aligned with each other, in opposite directions each by means of a drive 20 drivable reels 10 . 11 on, each with a pressurized water connection 12 is provided.

The device parts mentioned are all in one housing 1 housed, the front through doors 2 , prefers sliding doors, is locked, with the doors 2 are filled with a transparent glass.

The washing device 3 assigned is a Vorweichbehälter 6 , in which the stored and to be washed hose is pre-soaked. One of the two ends of the hose usually mounted hose connections is in a tractor 8th hanged on a tow truck 7 connected. This tow truck 7 is on a guide rail 9 mounted longitudinally displaceable.

By means of the tow truck 7 Now the hose through the washing unit 3 pulled and subsequently by means of the suction nozzles 4 dried.

After the hose start by means of tow truck 7 along the guide rail 9 in the area of the first reel 10 is brought, the hose connection with the pressure water connection 12 the first reel 10 connected, this pressure connection 12 on a connecting arm 13 is attached, which is designed as a supply pipe and a rotary connection 25 ( 2 ) and a pressure line 24 to a water tank 21 connected. It is, contrary to the representation in the 1 , the connecting arm 13 90 ° in the direction of the washing unit 3 turned.

After attaching the hose connection to the pressure water connection 12 becomes the first reel 10 rotated in a clockwise direction, with the case of the washing device 3 pulled hose around spacers 14 lays and is wound until the second hose connection at the other end of the hose, the second reel 11 adjacent, is positioned.

Now this hose connection with the pressure water connection 12 the second reel 11 , which is also connected to a connecting arm 13 attached, connected and the second reel 11 driven counterclockwise, with the first reel 10 with unrolling of the wound up hose it is turned the same direction, except for each reel 10 . 11 half of the hose is wound up.

The winding station 16 consists of one on a drive motor 26 connected base plate 18 , the two winding fingers 17 carries, which are arranged remotely and thus eccentric.

The drive motor 26 is on a sledge 28 movably mounted in such a way that the winding station 16 is movable transversely to the longitudinal extent of the tube.

The two on the reels 10 . 11 wound halves of the hose are connected by a hose route to which now the winding station 16 attacks.

For this purpose, by moving the drive motor 26 the two superimposed Wickelfinger 17 positioned so that the flattened in its shape hose between the two winding fingers 17 lies.

Now there is automatically a pressure test of the hose to which from the water tank 21 by means of a pressure pump 22 over the pressure lines 24 and the connecting arms 13 Pressurized water is pressed into the hose. An electronic control allows a well-known in the pressure test length expansion of the hose. After the pressure test, which is controlled in terms of time and pressure, valves are opened and the pressurized water can be drained via drainage pipes 23 in the water tank 21 flow back.

Now the winding station 16 rotationally driven and the hose from the reels 10 . 11 pulled, with simultaneous drainage. After completion of the winding process, the hose connections from the pressure water connections 12 solved and the hose is ready to roll rolled on the winding station 16 for removal. For this, the winding station moves 16 something back and the hose slips on discs 19 the reels 10 . 11 or a partition 29 , which separates the so-called working space of the housing from an aggregate space in which the drives 20 . 26 and the components necessary for pressure testing are positioned.

Incidentally, the reels 10 . 11 each via a means of a drive motor 20 operable chain drive 27 drivable while the device as a whole via a control panel connected to a control panel 5 is operable.

Instead of the arrangement of the winding station 16 in the upper part of the reels 10 . 11 , the winding station can 16 Of course, be arranged in the lower region, in which case the hose is guided accordingly.

As a burst protection, in the event that the hose should burst in the pressure test, are star-shaped struts 15 provided on the spacers 14 are attached, these spacers 14 on the other hand with the discs 19 are connected.
