Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire hose testing device.

[0002]

Fire hose must be regularly tested for damage and unsealed. About 2 fire hose for testing
It is already known to lay it in a 0 m long hose storage sideways and to connect it by means of a hose fitting to a filling connection pipe for feeding pressurized water into the fire hose. In advance, exhaust members are connected to the facing hose fittings of the fire hose. The air present in the fire hose can be exhausted through the exhaust member, after which the fire hose can be filled with pressurized water. As soon as air is exhausted, the exhaust member closes. After applying the required test pressure into the fire hose located in the containment, its inner wall is tested. Then, the damaged or unsealed part of the inner wall of the hose is marked, so that after the fire hose has dried, the damaged part can be identified and repaired.

This known test device is a test device, namely
The disadvantage is that it requires a great deal of space, especially for the storage of the fire hose. This drawback is the same even if the fire hose only fits half of its length in the hose enclosure. Such solutions are already known. However, here again, the major drawback is that the minimum length of the entire apparatus is approximately 12 m. The installation of the test equipment here again requires a very large space and requires a large and expensive effective area, and the effective area cannot be found everywhere, or its modification is associated with high costs. This test device also has the disadvantage that the person doing the test is injured if the fire hose is placed unshielded in the hose enclosure and the fire hose bursts under the action of the test pressure. At least extreme wetting of this person's clothing can occur. Covering the entire length of the hose with a protective device would not be feasible at an alternative cost due to the large spatial extent of the fire hose and the additional assembly connected.

From German Patent DE 44 13 273 is already known a device of the above-mentioned type in which the hose housing is formed as a winding frame. This configuration has the great advantage that the required space of the device can be significantly reduced. Furthermore, an arrangement of the protective cover is feasible and arranged.

[0005]

SUMMARY OF THE INVENTION The invention is based on the object of devising a test device for fire protection hoses which is simple in construction, inexpensive to manufacture and which requires little space. Furthermore, the danger to the person operating the device should be further eliminated.

This problem is solved according to the invention by the features of claim 1. The dependent claims relate particularly to other reasonable configurations of the invention.

According to the invention, the device has a hose compartment in which the hose to be tested is filled with pressurized water and is preceded by a hose cleaning device on the supply side, the hose being connected directly from the hose cleaning device. A hose dryer and a winder are provided on the outlet side of the hose, which is guided to the storage part. From this, an extremely space-saving and easy-to-operate arrangement of the device can be obtained.

In a particularly advantageous embodiment of the invention, the hose housing is formed by a support surface with lateral inner walls, the maximum length L of the support surface or its diameter D being
A filling connection for up to 30% of the length of the fire hose to be tested and for its first hose fitting and for its second hose fitting,
It is achieved by providing a connecting pipe with an exhaust valve so that the fire hose can be unrolled on the support surface during filling with pressurized water and a visual inspection is possible. As shown, the fire hose effectively mounted on the support surface allows the winding to be relatively easily visually inspected and marked during pressure water filling. , Fire hose windings are aligned and automatically unrolled.

It is rational when a filling connection pipe for filling the pressurized water is arranged in the region of the lateral inner wall. Unrolled hoses are especially good for visual inspection.
Evenly distributed over the support surface of the hose enclosure.

Further, when the filling connecting pipe for filling the pressure water is arranged at an angle to the side inner wall,
It is particularly suitable. It advantageously acts on the bottom of the hose housing to be unwound diagonally against the lateral inner wall of the hose.

In a particularly advantageous embodiment of the invention, the support surface and / or the lateral inner wall of the hose enclosure are formed in a grid pattern, so that a visual inspection of the underside of the hose and a retraction of the marking means at the damaged point is possible. Is achieved by.

In accordance with a preferred embodiment of the present invention, the support surface of the hose enclosure is pivotally in a substantially horizontal position during withdrawal of the fire hose and is tilted about the joint to a horizontal position. As a result, it is possible to access the lower surface of the bottom and to easily perform visual inspection and mark the damaged portion even on the lower surface of the hose.

Within the scope of the invention, it is provided that a substantially transparent protective cover with an access opening is arranged above the hose housing. It is ensured that the person to be tested is not endangered or his clothes do not get wet in the case of installation of the fire hose under the action of the test pressure.

As long as the hose compartment is arranged in a horizontal position in the pressure water receiving tank, it is achieved that the test water is collected and not dispersed in the air in the case of installation of the fire protection hose.

The present invention is capable of various embodiments. To further clarify its principle, two embodiments are shown and described below.
