The advantage is that the range of use and the maneuverability of the Rettungshubgeräts is significantly expanded.

Description

The The invention relates to a rescue hoist according to the preamble of Patent claim 1.

With the subject of DE 197 12 408 A1 has become known a fire engine, which arranges a rescue basket at the free end of an emergency descent ladder.

One such a fire engine is not comparable to a rescue vehicle, because a fire ladder requires a ladder, must be climbed by at least one operator to to get to the place of the mission.

With arranged at the front free end of the ladder rescue cage can if necessary persons or objects are salvaged.

One such vehicle is only for firefighting operations suitable and determined and requires that the aerial ladder with difficult motion control in a straight line to a building or a higher altitude Used is approached.

at the use of such ladders is accordingly the disadvantage that they are difficult to maneuver are moved and only in an inclined position to a site can be which makes the purpose very difficult. It is not, for example possible, to use such a rescue ladder as Rettungshoubgerät, in which it it's about, one of a parapet Covered and lower-lying site to achieve.

As well it is not possible with the known aerial ladder, locations below to reach the location of the vehicle.

The invention is therefore the object of an arrangement according to the DE 197 12 406 A1 educate so that the application area and the maneuverability is significantly expanded.

to solution the task is the invention by the technical teaching of claim 1.

essential Feature of the invention is that now according to the invention a rescue hoist from at least a cantilever arm, which in a horizontal pivot joint is arranged on a turntable of a vehicle; that at the free End of the boom is arranged an articulated arm, the telescopic is and that at the free end of the articulated arm a rescue basket is arranged.

at the given technical teaching gives the essential advantage that now altogether on an aerial ladder is waived and instead only several times to each other telescopic arms are proposed.

Essential Here is that at the free end of a multiply telescopic Auslegerarmes a pivot joint is arranged on the pivotally a Articulated arm attaches, which in itself again telescoped at least once is trained.

In order to There is the significant advantage that with such an arrangement a rescue hoist Now difficult-to-reach locations can be easily achieved can.

going For example, it is a rescue mission in the interior of a To drive upwards open silos, then it is possible, the boom up aslant drive under the silo edge, then the pivotally attaching it Articulated over the Silorand out and sink into the silo, there for example an accident Person to be invited into the rescue basket.

As well it is possible with the feature of the invention to approach a site, which, for example, lies beyond a higher parapet.

One Such a case is, for example, a site on a bridge at which is about the bridge railing vertical to move down to one near or below the bridge Use (also in the water) to drive.

such Applications are unmanageable with a conventional aerial ladder and hence the scope of the present invention a boom with a pivotally mounted thereto, telescopic Articulated arm in front.

In a development of the invention, it is also provided that a such rescue hoist also for fire fighting is used, which is great Offers advantages.

For this In the application, it is necessary that longitudinal of the boom and the pivotally hinged articulated arm a telescopic water supply is carried along.

At the rescue basket is then at least one Water cannon arranged, which is supplied by the telescopic water supply along the boom and the articulated arm with high pressure water.

In order to can also difficult to reach extinguishing works completed with the Rettungshubgerät invention be what with a conventional Aerial ladder not possible is.

The use of an articulated arm has the following advantages:
This device allows a much faster and more precise adaptation and thus positioning of the rescue cage over the conventional competitors. Thus, a façade can be raised without accomplishing several movements.

The Overall concept of the life-saver also stands out in its constructive Form substantially. In particular, due to the fact that instead from usual Systems cylinders with chains for the telescopic arm, as here a special hy-cylinder combination, are used which also ensure a negative outreach.

A Another object of the invention is to provide a Rettungshubgerät the above mentioned type as possible quickly operational close. For this purpose proposes the invention provides a so-called terrain regulation.

in the Essentially, the upper part is mounted from the turntable via an axle, pivoting made, so that in the consequence with a tilt of the vehicle over two Hydraulic cylinder brought the upper part in a horizontal position becomes. This leveling to the horizontal takes place continuously during the rotation. This has the one advantage that a leveling over the entire vehicle the supports not below 7 ° is necessary and therefore the device can be used immediately.

at the figurative Hubrettungsgerät is this terrain regulation in addition applied to the level compensation by means of support cylinders: thus ergib is still an additional Advantage, that is the Use of the device can be extremely steep Terrain; this means Balancing a maximum of 7 ° Te3rrainregulierung as well as additional Support cylinder compensation 7 ° = thus 14 ° -.

The Invention proposes So the combination of a conventional Terrain Regulation ago, the known manner from front and rear outriggers in the form of cylinders whose piston-side rod with a corresponding ram plate is supported on the ground.

According to the invention known support with a dynamic and constantly in use tilt drive (automatic leveling) coupled to the Hubrettungssatzes.

at This dynamic tilt drive is the Hubrettungssatz over a pivoted axis swiveled so that it is now possible for the first time additionally to the conventional one 7 ° terrain regulation one more extra To achieve compensation of, for example, up to a maximum of 14 °.

This improves and accelerates the use of such a vehicle essentially dimensions.

One such vehicle can be driven to the site and it will be immediately at the free outer ends arranged cylinder out, so as a front and rear support to build.

Also if the entire vehicle is still at an angle with the boom However, the cantilever arm can already be moved out because in another step now the automatic leveling is turned on, the inclination of the entire Hubrettungssatzes in relation to the cutting surface leads and so to bring the fifth wheel in an absolutely vertical position and the Cantilever arm horizontally and vertically with respect to the desired work area align.

In order to is a particularly fast use of the vehicle possible because even overcome extreme inclinations can be and still achieved a stable state of the Rettungshubgerätes and on the other hand a preliminary one Positioning of the chassis on the footprint is possible then afterwards during the operation the boom arm to turn on automatic leveling.

Of the Subject of the present invention does not arise only from the subject matter of the individual claims, but also from the combination the individual claims among themselves.

All in the documents, including Summary of information and features, in particular the spatial training shown in the drawings as claimed essential to the invention, as far as they individually or in Combination opposite the prior art are new.

In the following the invention is based on merely explanatory drawings illustrating an execution path. Here are from the drawings and their description further features essential to the invention and advantages of the invention.

It demonstrate:

10 : the same representation as 9 with a partially disguised vehicle.

The rescue hoist 1 to 1 consists essentially of a vehicle 2 , which on a chassis a turntable 27 carries on which a turntable 28 is arranged; at the upper free end of the one end of a multi-telescopic boom 3 is pivotally attached.

The boom arm 3 consists essentially of three mutually telescopic part arms 9 ; 10 . 11 ,

At the upper free end of the partial arm 11 is a swivel joint 12 arranged on which the inventive telescopic articulated arm 13 is articulated. The articulated arm 13 in turn consists of two telescopically arranged and telescopically arranged partial arms 14 . 15 , wherein at the upper free end of the arm part 15 a swivel joint 16 is arranged at which a rescue cage 4 is attached.

1 shows the working field 5 of the rescue hoist according to the invention, from which it appears that it is operational over a wide range of applications.

From the straight, outstretched position shown on the left side (which could also be reached with a fire engine ladder), the rescue cage 4 be lowered laterally until it is in a horizontal, pivoted position, as with a single-line representation in 1 is shown.

It is important now that by appropriate pivoting of the articulated arm 13 also below the horizontal position an insert of the rescue cage 4 '' is possible or even the articulated arm 13 ''' can even be swung vertically down to the rescue cage 4 ''' to bring in a lowered position.

The working field 5 is thus through the opposing positions 6 . 7 characterized.

The 2 shows further details of the application, where it can be seen that even at the free front end of the rescue cage 4 a water cannon 17 can be arranged so as to use the Rettungshubgerät also for firefighting.

It goes without saying that on the rescue cage 4 Still other technical facilities may be arranged, such as a television camera, a condition monitor, a control station and the like.

The 2 shows the variability of the use of the Rettungshubgerätes because the rescue cage 4 in a variety of positions due to the telescopically formed articulated arm 13 can be moved.

It is important that when using a water cannon 17 at the rescue cage 4 also a telescopic water supply to the boom 3 and the articulated arm 13 must be guided along.

This telescopic water supply consists according to 3 from a multiply telescopic water pipe 20 , which continues with sub-pipes, with a flexible connection at the upper free end 8th between the boom side water pipe 20 and the knickarmseitigen water pipe 18 . 19 consists.

Accordingly, too this water pipe telescopic executed.

The 4 to 8th show that along the entire cantilever arm 3 and the articulated arm 13 a foldable emergency ladder 21 is guided along, which is telescopic and consists of individual conductor segments, as in 8th is shown.

8th shows as a section along the line BB in 5 in that in the interior of the cantilever arm 3 the mehrfaeh telescopic cylinder is arranged, the individual arms 10 . 11 moves to each other.

8th also shows the telescopic water supply 18 . 19 . 20 ,

In the 4 . 5 and 7 Further details of an automatic leveling are shown.

The chassis 22 of the vehicle 2 is through an upper amplifier frame 23 reinforced, at its opposite ends in each case a front support 25 and a rear support 26 are arranged.

In the back of the amplifier frame 23 is in a known way a turntable 27 arranged, the rotatable part with a turntable mounted thereon 28 is connected, at the rear free end of the pivot bearing 36 for the pivotal mounting of the cantilever arm 3 is arranged.

The boom arm 3 by the way by two lifting cylinders 33 supported and moved.

The vehicle 2 carries in the front a driver's cab 24 ,

It is important that in the area of the turntable the level control according to the invention 29 is arranged, in connection with 9 and 10 will be discussed in more detail.

According to 9 is the known terrain regulation from two sides of the chassis 22 . 23 attaching and oppositely directed support beams 31 , where the front support by the same support beams 30 is realized.

Every stringers 30 . 31 carries a sliding telescope part 32 , at the front free end fixed in each case the front and rear support 25 . 26 is arranged.

Each support consists essentially of a cylinder 34 whose piston rod is connected to a gauging plate that stands up on the work surface.

What is important now is that the automatic leveling is effected by the fact that the entire chassis 22 . 23 about a pivot axis lying in a horizontal plane 35 is pivotable, the above the turntable 27 is arranged. This is the turntable 28 provided with an automatic leveling.

The adjustment of the swivel position of the fifth wheel 28 This is done by an electronic balance 38 achieved, which according to two spaced-apart hydraulic cylinder 37 controls.

The respective hydraulic cylinder 37 is with its one end on the tilting part of the fifth wheel 28 arranged and supports with its other part at the top of the turntable 27 off, leaving the turntable 28 through the electronic scale 38 always kept in a vertical position.

The adjustment of the vertical position of the fifth wheel is fully automatic and dynamic, because during the entire operating time, the hydraulic cylinder 37 perform an automatic compensation.

This is a particularly rapid use of Rettungshubgerätes possible because the Rettungshubgerät with the front and rear supports 25 . 26 is first moved to the site and on the cylinder 34 the bottom support is made.

Once this support is made, the automatic level control becomes 29 switched on and during extension of the boom 30 and unfolding the articulated arm 13 becomes the turntable 28 in the in 9 shown vertical position pivoted.

The 10 shows more details of a partially clad vehicle in which the same parts after 9 are provided with the same distortion marks.
