^M underwater excavator "

The invention relates to an underwater excavator with a submersible and self-propelled ship equipment equipped with machinery and equipment for carrying out dredging work on the The bottom of the army, lake or river is provided and from the outside is supplied with electrical energy via electrical cables

In an already known such underwater excavator, the submersible Ship equipment (the submersible hull) on the dredged The base can be moved by means of construction chains (crawler tracks) and is arranged outside the chassis for the time of the excavation work large-area support devices, in particular support feet with support plates, can be fixed (see French patent specification 1 553 816) «

A rational execution of the dredging work can, however

only by dredging during port movement of the underwater dredger achieve. This port movement during the dredging is only possible on firm ground by means of the crawler tracks possible, which however is not available everywhere and therefore the well-known underwater excavator cannot be used everywhere. In addition, on slippery ground, a directionally stable (dead straight) port movement is extremely difficult or only to a limited extent possible. The often desired adherence to a predetermined dredging line prepares at least for some types of soil and / or difficulties with existing transverse channels. Another disadvantage is that between the individual Chain links and the like. Soil caused great wear and tear and the associated susceptibility to movement organs·

The object of the invention is to provide an improved underwater dredger to create the type mentioned at the beginning, which has a simply constructed movement device (travel drive), which on the various sea, lake or plus grounds a perfect, directionally stable port movement Allows in a predetermined straight-line travel as well as any necessary cornering.

According to the invention, this object is achieved in an underwater dredger of the type mentioned at the outset in that a winch system is used as the ship equipment moving device two independently operable, each one with its other end on one outside of the underwater excavator attached rope receiving winches is arranged on the ship equipment.

In a preferred embodiment, the winch system is arranged in the rear area of the ship's equipment on the upper deck and the ropes are each connected via a guide (a fixed point) provided at the bow-side of the ship's equipment to a position-adjustable fastening point (support point).

An exemplary embodiment of the invention is shown in the drawings. Show it:

Fig. 1 is a side view of a submersible underwater dredger in working position,

Fig. 2 is a top view of the same underwater excavator (with dismantled Tauci>_t;^.; E ε.3,3 lounge for the operating personnel hüq

FIG. 3 shows a cross section through the same underwater excavator according to section line II in FIG. 1.

An underwater excavator according to the invention has a floodable Self-propelled submersible marine equipment (hulls) 11 fitted with tanks Io, lying on the bottom 12 of the sea, Can be slid along the lake or river and at the bow end with a milling-suction device 13 »as a dredging device, Is provided. A diving bell 14 holds all of the underwater dredger controls as well as at least one Operator. The underwater excavator is supplied with electricity (energy) from the surface of the water via electrical cables.

For the locomotion and steering of the resting on the ground 12, on the bottom at the ends and sides with a lower driving resistance (sliding resistance) resulting inclined surfaces Equipped ship equipment 11 is a winch system with two each at one end on one outside of the underwater dredger non-illustrated attachment point (support point) and attached to a winch 15, 16 at the other end Ropes (cables) 17, 18 are provided.

The winches 15 »16 of this winch system are in the rear area of the ship's equipment 11 is arranged on its upper deck and has an electrohydraulic drive device located below deck 19 connected. They are at the bow end

1 0981 7/1106 -5-

ropes 17, 18 each running in a side area of the ship's equipment 11 in a guide (in a plague point) 2o led. In order to enable steering and cornering of the ship equipment 11, the winches 15 » move independently of each other, i.e. differently. In addition, their drive is based on the amount of dredged (cleared) material adjustable.

Both winches 15, 16 are synchronized for straight underwater excavator locomotion and for cornering moved differently - the winding of the rope pulls the ship's equipment 11 in the direction of the Attachment points (support points). If the entire length of the rope is wound up, those are turned away from the hull Rope ends receiving support points changed location and fixed again in terms of position and it can continue dredging take place.

A particular advantage of the underwater excavator moving device according to the invention is that a straightforward dredging line can be simply maintained by even pulling (winding) both ropes is guaranteed.

It goes without saying that a large number of variants and / or modifications can be made to the disclosed underwater excavator according to FIG Contribute to the invention without departing from the scope of the invention.
