Suction dredger and bulk module for a suction dredger Description

The invention relates to a suction dredger, comprising a chassis with mounted thereon, driven suction fan, a proboscis and arranged between the suction nozzle and suction fan in the flow direction tiltable about a tilting axis container for separating and collecting sucked up material and with a telescopic device for displacing the tilting axis of the container.

Moreover, the invention relates to a bulk module for mounting on a chassis of a suction dredger, comprising a platform, at least one hydraulic linear motor and at least one telescoping device and a container.

From the utility model DE 20 2005 006 671 a generic same suction dredger with suction fan and tiltable container is known.

The document JP 58222231 discloses a suction dredger in which a

Emptying of the container by means of a discharge flap, which is arranged in the container bottom, in the region of the rear end of the container.

Furthermore, DE 0 613 983 also describes a suction dredger, in which a conveying device for removing the collected in the container, sucked up material is provided in the container bottom.

Finally, DE 299 12 070 discloses a suction dredger in which the container tiltable for emptying is laterally tiltable about a tilting axis extending parallel to the longitudinal axis of the chassis.

The known suction dredger have the disadvantage that the container in which the suction dredger emptied the material the cramped workspace

Constrict construction sites additionally. Once the container is filled, a truck drives to the construction site to exchange the container for emptying. The object of the invention is therefore to facilitate the departure of groupage and to reduce the space required for at least temporarily.

[A1] This object is achieved in suction dredger, comprising a chassis with mounted, driven suction fan, a proboscis and a arranged between the suction nozzle and suction fan in the flow direction tiltable about a tilting axis container for separating and collecting sucked up material in that the tilting axis above a Container bottom of the container, preferably in the upper half of

Container is arranged.

By raising the height of the tilting axis and the upper edge of the container over which the groupage is dumped, remains at a higher

Level. The level is chosen so that it exceeds the platform height of a truck. Thus, the suction dredger can empty the container directly on the truck, without the need for additional containers. There is therefore more space on the construction site and the construction site must be approached less frequently.

Characterized in that the tilting axis is arranged above the container bottom, preferably in the upper half of the container, the underside of the container pivots when tilting in the direction of the vehicle center. If the axis of rotation is arranged in the upper region of the container, it lies above the upper edge of the loading area of a transport vehicle, so that emptying can be emptied directly onto the loading area.

If the tilting axis above the container bottom but below the

Is arranged edge of the container, the distance between the tilting axis and edge of the container bridged the distance between suction dredger and

Transport vehicle. If this is not sufficient, it is advantageous if the tilting axis is horizontally displaceable, whereby the distance between a suction dredger and a transport vehicle can be bridged.

[A2] In a preferred embodiment, the tilting axis is arranged parallel to the longitudinal axis of the chassis so that the container can be emptied along the longitudinal side of the suction dredger. Since the container is longer than it is wide, the lateral tilting is thus faster and therefore more economical. Construction vehicles are usually large and confusing. For reloading, they are easier to place next to one another than at right angles to each other.

[A3] At least one hydraulic linear motor is provided for tilting the container. Its first end is preferably fixed to a front wall and / or on a rear wall of the container and its second end is preferably fixed to a structure of the chassis spaced from the tilting axis. As a result of this arrangement, the hydraulic linear motor pivots the container about the tilt axis during extension. Piston-cylinder actuators are tried and tested and reliable. By each mounted on the front wall and rear wall and operated synchronously hydraulic linear motor moments around the transverse axis of the container are avoided.

[A4] In a preferred embodiment there is a safety rope, the safety rope having a first end preferably being arranged on the structure of the suction dredge and a second end being arranged on a front wall and / or rear wall of the container. The safety rope secures the container when reaching the end position when tilted against a complete tip over in the event of a ruptured hydraulic cylinder. Because the safety rope secures the container from tipping over, it remains

Overall center of gravity of the vehicle within the vehicle boundaries, so that the suction dredger does not tip over.

[A5] To bridge the distance between suction dredger and

Transport vehicle, the suction dredger on a telescopic device for displacing the tilting axis of the container, wherein the tilting axis is arranged at maximum extended telescoping device outside a longitudinal side of the suction dredger. This simplifies the emptying of the container onto the bed of the neighboring vehicle. In practice you can

Suction dredger and transport vehicle due to their size or

Substrate conditions can only be juxtaposed within certain tolerances.

[A6] Advantageously, the telescoping device comprises at least one hydraulic Achsverstellantrieb and a linear guide. Such running telescopic devices are reliable and infinitely adjustable. Therefore, different heights of flatbed vehicles can be achieved. The height of the tilting axis can be divided so that too large impacts are avoided by the falling material on the bunk.

[A7] When the telescoping device is at an angle between 0 ° and 90 °, in particular between € ° and 30 °, with respect to the vertical

Preferably, 20 °, the tilting axis is automatically displaced vertically to the longitudinal side of the suction dredger when lifting with increase in height. Separate drives for the horizontal and vertical components of the movement are therefore not required.

[A8] Desirably, a bolt to shorten the

Safety rope, in particular an extendable bolt, preferably in the chassis parallel to the longitudinal axis arranged bolt, embedded in the structure. The capture and deflection of the safety rope by means of a bolt is easy and inexpensive.

[A9] The object is also achieved by a bulk module, preferably for mounting on a chassis of a suction dredger, comprising a superstructure, at least one hydraulic linear motor and at least one

Telescoping device and a container, solved by the

Tilting axis is arranged above a container bottom of the container, preferably in the upper half of the container.

Such bulk modules can be placed on different types of vehicles. Thus, the absorption of material in the container and its direct emptying on flatbeds of transport vehicles is independent of

Vehicle type possible. A stationary use without a vehicle is conceivable.

A preferred embodiment of the invention will be explained by way of example with reference to figures. Show it:

Figure 6 shows a structure with tilted container when retracted

Telescoping device.

Figure 1 a shows a suction dredger 1 with a lid 24 which closes a container 5. The container 5 rests on the chassis 2 in a transport position. From front to back, the suction dredger 1 is divided into a

Cabin 26, equipment cabinet 27 and suction fan 3. It follows the container 5 with lid 24. Before and behind the container 5, a support 25 is welded to the chassis 2 in each case. At the rear end of the lid 24 opens a suction pipe 4. For this purpose, an opening in the lid 24 is present (Figure 1 b).

Figure 1 b shows the suction dredger 1 according to Figure 1 a with two parallel

Side walls 7 and a rear wall 9 in a rear view, i. it is looked at the rear of the suction dredger 1. From top to bottom, the figure shows that the lid 24 with a lifting device 29 and with a

Support strut 28 is hingedly connected. By extending the

Lifting device 29, the lid 24 is a lid rotation axis 30th

pivoted so that the container 5 is opened up to the side. The support strut 28 is welded at an angle to a structure 16. On the left side is the telescoping device 10, which consists of a hydraulic

Achsverstelleinrichtung 21 and a linear guide 18 composed, also at an angle to the structure 16 verschwei eats. The structure 16 is fixed with connected to the chassis 2. In approximately the middle, there is a tilting linear motor 13 in this view. In the shown transport position of the container 5, the side walls 7 of the container 5 lie parallel to two longitudinal sides 17 of the container 5

Suction dredgers 1. In the support strut 28, a bolt 19 is inserted. Due to the weight of a safety rope 20 (Figures 5/6) this depends down in the relaxed state, so that the extended bolt 19 the

Safety rope 20 safely captures. The tilting linear motor 13 is connected by means of a bracket 31 with the rear wall 9 of the container 5. For this purpose, the console 31 is verschweis to the container 5 via a frame 36. The bracket 31 thus forms a cantilever, which tapers from its welded end to its free end. At the free end, the bracket 31 is pivotally mounted on the hydraulic tilt linear motor 13.

Figure 2 shows the structure 16 with container 5 and chassis 2. The structure 16 is shown in its transport position. In this transport situation are

Telescoping device 10 and tilt linear motor 13 retracted. in the

retracted state, the tilt linear motor 13 is at an angle to a

Vertical 22 employed. A tilting linear motor shaft 35 of the

Kipplinearmotors 13 extends parallel to the support strut 28. In the transport position is a Kippachsenmitte 1 1 above the supports 25, so that

Vertical forces, which on the tilt axes 1 1 in the telescoping device

10 be discharged over the support 25 in the ground. For this purpose, the linear guide 18 of the telescoping device 10 with the structure 16 and the supports 25 is welded.

FIG. 3 shows the structure of FIG. 2 during the discharge process. So that the contents of the container 5 on the bed (not shown) of a

Transport vehicle (not shown) can be tilted, is the tilt axis

1 1 extended by means of the telescoping device 10 in its end positions. The end position of the tilting axis 1 1 is located outside the vehicle longitudinal side. The tilting axis 1 1 is offset from its transport position by a height 32. The tilting axis 1 1 is above the height of platforms of conventional transport vehicles, so that the contents of the container 5 can be tilted onto the bed of the transport vehicle. In the emptying position, the lid 24 by means tilted the lifting device 29, so that by a simultaneous extension of telescoping device 10 and Kipplinearmotors 13 of the container 5 can be lifted from its transport position into the upper tilt position.

Figure 4a shows the suction dredger 1 in its side view - namely the

Driver's side - with tilted container 5. The tilt linear motors 13 are maximally extended. In practice, the supports 25 for lifting the rear part of the suction dredge 1 are lowered to the ground.

Figure 4b shows the suction dredger 1 of Figure 4a in the rear view, i. it is looked at the rear of the suction dredger 1. To tilt the container 5, the tilting linear motor 13 is maximally extended, so that the container 5 was rotated about the tilting axis 1 1 and its contents can slip out.

Figure 5 shows the structure 16 in a rear view with tilted by 135 ° C transport container 5 in the extended position of

Telescoping device 10. The safety rope 20 is stretched and secures the container 5. When the telescoping device 10 is extended, the pin 19 has retracted. The entire rope length is required for securing.

Figure 6 shows the container 5 with structure 16 of Figure 5 with tilted container 5 in the transport position of the telescoping device 10. The bolt 19 is extended, so that the safety rope 20 was caught by the pin 19 during tilting and is now deflected. The tilting linear motor 13 is mounted with its piston rod end, the second end 15 of the structure. The end 14 is mounted in the console.

Before the container 5 is emptied, the supports 25 are first lowered so that the suction dredger is defined and stably positioned relative to the substrate. To empty the container 5, the lid 24 is first opened by means of the lifting device 29. Following this, depending on the height of the platform of a ready for takeover of the container contents transport vehicle (not shown), which is parallel to the suction dredger 1, the tilting axis 1 1 be adjusted by means of telecopying device 10 in height. For this purpose, the tilting linear motor 13 and the telescoping device 10 are extended at the same time until the tilting axis 1 1 desired height has reached above the bed of the transport vehicle. Following this, by extending the tilt linear motor 13, the container 5 is tilted until its contents slip onto the bed of the transport vehicle. For this purpose, the tilting linear motor 13 is extended. In the emptying situation, the

Tilting axle 1 1 a tilting axle height 33 of approx. 2m. After dumping of container material, the container 5 is moved back into its transport position, the lid 24 is closed and the supports 25 are retracted.
