Abstract

A rescue vehicle as a wheel-mounted chassis stabilised by outriggers, and a load platform with a telescopic arm with a horizontal swivel-mount. The distal end of the telescopic arm has a rescue platform with sidewall.

Description

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

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

Such a fire engine is not comparable to a rescue vehicle, because in a fire engine a turntable is required, from at least one operator must be boarded to the place of the Use to arrive.

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

Such a vehicle is only suitable for firefighting operations and determines and sets advance that the aerial ladder with difficult movement control in a straight line is approached to a building or a higher location.

When using such ladders there is accordingly the disadvantage that They are difficult to maneuver and only in an inclined position to a job site can be moved up, which makes the purpose much more difficult. It is For example, not possible, such a rescue ladder as Rettungshubgerät too to use one that is covered by a parapet and to reach a lower location.

Likewise, it is not possible with the known aerial ladder, locations below the Location of the vehicle to reach.

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

To solve the problem, the invention by the technical teaching of Claim 1 characterized.

An essential feature of the invention is that now according to the invention a Rettungshubgerät consists of at least one arm, which in one horizontal pivot joint arranged on a turntable of a vehicle is that at the free end of the boom a Knickarm is arranged, the telescopic and that at the free end of the articulated arm a rescue cage is arranged.

Given the technical teaching, the essential advantage, now altogether on an aerial ladder is waived and instead only several times telescopic arms are suggested to each other.

Essential here is that at the free end of a multiple telescopic Auslegerarmes a pivot joint is arranged on the pivotally an articulated arm attaches, which is again formed telescopically at least once.

This results in the significant advantage that with such an arrangement of a Rettungshubgerätes now difficult to reach locations easily reached can be.

Is it about, for example, a rescue operation in the interior of an upward To drive open silos, then it is possible, the cantilever arm at an angle under the Silokante to drive, then the pivotally attaching articulated arm over the Silorand out and sink into the silo, there for example a accident victim who is invited to the rescue cage.

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

Such a case is, for example, a location on a bridge, which is why goes to move vertically down the bridge railing to a in the Near or below the bridge site (also in the water) to approach.

Such applications are unmanageable with a conventional aerial ladder and therefore the scope of the present invention provides a Arm with a pivotally mounted thereto, telescopic articulated arm in front.

In a further development of the invention, it is otherwise provided that such Rescue hoist is also used for fire extinguishing, which offers great benefits.

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

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

This can also be difficult to reach extinguishing with the Rescue stroke device according to the invention are completed, what with a conventional aerial ladder is not possible.

The use of an articulated arm has the following advantages:

This device allows a much faster and more precise adaptation and thus positioning the rescue cage over the conventional ones Competitors. It can thus be raised a facade without this several movements to accomplish.

The overall concept of the life-saver rises also in its constructive Form substantially. In particular, due to the fact that instead of usual Systems cylinders with chains for the telescopic arm, as here a special hy-cylinder combination, be used, which is also a negative projection guarantee.

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

Essentially, the upper part is mounted from the turntable via an axle, made pivotable, so that in consequence at a tilt of the vehicle The upper part is brought into a horizontal position via two hydraulic cylinders. This leveling in the horizontal takes place continuously during the rotary movement. This has the advantage that a leveling of the entire vehicle over the Supports below 7 ° is not necessary and therefore the device can be used immediately.

In the subject Hubrettungsgerät this terrain regulation is additional applied to the level compensation by means of support cylinders. This is another one additional advantage, that is, the use of the device can be extremely steep Terrain, that means compensation of maximum 7 ° Te3rrainregulierung and additionally Support cylinder compensation 7 ° = thus 14 ° -.

The invention thus proposes the combination of conventional terrain regulation before, the known manner from front and rear supports in the form consists of cylinders whose piston-side rod with a corresponding Punching plate is supported on the ground.

According to the known per se support with a dynamic and constantly in use tilt drive (automatic Level compensation) of the Hubrettungssatzes coupled.

In this dynamic tilt drive the Hubrettungssatz is about a pivoting axis pivoted so that it is now possible for the first time, in addition to the conventional 7 ° terrain regulation still an additional compensation of for example, up to a maximum of 14 °.

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

Such a vehicle can be driven to the site and it will be instant pulled out the arranged at the free outer ends of the cylinder, so as a to form front and rear support.

Even if the entire vehicle should still be at an angle with the boom, However, the cantilever can already be moved out because in another Step now the automatic leveling is turned on, the one to Inclination of the entire Hubrettungssatzes in relation to the Aufstanzfläche leads and so to bring the fifth wheel in an absolutely vertical position and the boom align horizontally and vertically with respect to the intended work area.

For a particularly fast use of the vehicle is possible, because extreme inclinations can be overcome and still a stable state of Rescue stroke device is achieved and on the other a preliminary positioning of the chassis on the footprint is possible, then afterwards during the Actuation of the boom arm to turn on the automatic leveling.

The subject invention of the present invention does not only result from the Subject of the individual claims, but also from the combination of individual claims among themselves.

All information disclosed in the documents, including the summary and features, in particular the spatial illustrated in the drawings Training, are claimed as essential to the invention, as far as they individually or in Combination over the prior art are new.

In the following, the invention will be described with reference to only one embodiment illustrative drawings explained in more detail. Here are the drawings and their description further features essential to the invention and advantages of Invention forth.

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 down vertically, so as to bring the rescue cage 4 '' in a lowered position.

The working field 5 is thus by the opposing positions 6, 7th characterized.

FIG. 2 shows further details of the area of application, where it can be seen that also at the free front end of the rescue cage 4 a water cannon 17th can be arranged, so the rescue hoist also for extinguishing use.

It goes without saying that the rescue cage 4 even more technical Facilities may be arranged, such as a television camera, a Condition monitor, a helm and the like more.

Figure 2 shows the variability of the use of Rettungshubgerätes because of Rescue basket 4 in different positions due to the telescopic trained articulated arm 13 can be moved.

It is important that when using a water cannon 17 on 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 Figure 3 of a multiple Telescopic water pipe 20, which continues with partial pipes, wherein the upper free end of a flexible connection 8 between the boom side Water pipe 20 and the knickarmseitigen water pipe 18, 19 consists.

Accordingly, this water pipe is designed to be telescopic.

FIGS. 4 to 8 show that along the entire cantilever arm 3 and the Knickarmes 13 a multiply folding emergency ladder 21 is guided along, the is telescopic and consists of individual conductor segments, as shown in Figure 8 is shown.

Figure 8 shows a section along the line B-B in Figure 5, that in the interior of the Auslegerarmes 3 of the multi-telescopic cylinder is arranged, the individual sub-arms 10, 11 to each other.

FIG. 8 also shows the telescopic water guide 18, 19, 20.

In Figures 4, 5 and 7 are further details of an automatic Level compensation shown.

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

In the rear region of the amplifier frame 23 is a known manner Turntable 27 arranged, the rotatable part with a patch on it Turntable 28 is connected, at the rear free end of the pivot bearing 36 is arranged for the pivotal mounting of the extension arm 3.

The boom 3 is supported by two lifting cylinder 33, moreover emotional.

The vehicle 2 carries a driver's cab 24 at the front.

It is important that in the area of the turntable, the inventive Level control 29 is arranged, to which in connection with Figure 9 and 10 closer will be received.

According to Figure 9, the known per se terrain regulation consists of two laterally on Chassis 22, 23 attaching and oppositely directed support beams 31, wherein the front support is realized by the same support beam 30.

Each support beam 30, 31 carries a displaceable telescopic part 32, at the front free end fixed respectively to the front and rear supports 25, 26th is arranged.

Each support consists essentially of a cylinder 34, whose Piston rod is connected to a gauging plate, which is on the work surface gets up.

What is important now is that the automatic leveling is effected by the entire chassis 22, 23 to a lying in a horizontal plane Pivot axis 35 is pivotable, which is arranged above the turntable 27 is. In this way, the fifth wheel 28 with an automatic Level compensation provided.

The regulation of the pivotal position of the fifth wheel 28 is in this case by a electronic balance reaches 38, which correspond to two from each other spaced arranged hydraulic cylinder 37 controls.

The respective hydraulic cylinder 37 is connected at one end to the tiltable part of Drehschemels 28 arranged and is supported by its other part on the Top of the turntable 27 from, so that the fifth wheel 28 through the electronic balance 38 is 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 a perform automatic compensation.

This is a particularly quick use of Rettungshubgerätes possible because the Rettungshubgerät with the front and rear supports 25, 26 first on the place of use is moved and the cylinders 34, the bottom-side support is made.
