Hose cable

The invention relates to a smart cable made of at least a sole made of flexible material, especially plastic or rubber.

Pur different areas of application in marine technology and ira area In the inland waters, connection systems are required which, in addition to a tensile coupling, e.g. between a ship and a sole body, can also take on other tasks.

The invention is based on the object © * © in hose cables create that both transmit electrical energy and can take over the transport of oases or liquids and In addition, high mechanical loads, especially tensile loads, records.

According to the invention, this is achieved by concentric to the longitudinal axis of the cable on the outer circumference of the hose or on a bundle of flexible tubes with tensile strength and parallel to these in the same plane electrical lines! At least one layer. In this construction according to the invention, the tensile strands arranged around the hose take on the loads that occur. According to the invention, a compact sole tube cable is created that connects the functions of an elastic tube and that of a tensile rope and enables the transmission of electrical cast iron. For reasons of manufacture, it is particularly advantageous if the oil-trimmed lines have the same dimensions as the strands.

According to an advantageous embodiment of the invention, the Tensile strands and the electrical lines wire, band or Litzenförraig formed. In doing so, the strands can come out Wires, threads or bands made of metal or plastic or made of glass fibers. Are particularly suitable as strand material highly scattered plastics. The use of plastic is increasing this purpose is particularly advantageous because it provides a considerable reduction in the weight of the cunning eye compared to the from braided wire ropes old metal strands, according to the invention it is advantageous «if the electrical lines are off one made of a metallic braided conductor with a plastic core and an outer insulating sheath · Due to this design, the electrical lines are flexible and electrically connecting them to the strands prevented. According to the invention, the tensile strands and the electrical lines with a long sagging length around the sole au oh or the bundle of soles. Have long lay lengths the advantage that they only have low levels of torsion and pressure

Exercise on the flexible hose “According to the invention, it is special advantageous if the number of layers of the reinforcement elements is an even number and the individual layers are one to the other have opposite direction of impact. Through this construction it is achieved that those caused by the individual layers Torsional loads cancel each other out and thus no stresses occur on the hose.

According to a further embodiment of the invention, the tensile strands and the electrical lines can run parallel to the longitudinal axis of the hose cable. This arrangement has the advantage that pressure and torsional loads on the hose are excluded from the outset. To hold and fix the strands and the electrical lines, these are wrapped according to the invention with a plastic film or with a braid made of plastic threads. Another possibility for fixing these elements in place is to embed them in the jacket of the hose made of rubber or plastic using a vulcanization process. This embodiment is advantageous because it eliminates the need for additional wrapping. According to the invention, the tensile strands and the electrical lines are jointly surrounded by a protective sheath made of elastic material. This outer protective sheath serves to protect against external mechanical and chemical influences and gives the sole-tube cable a smooth and therefore aerodynamic outer surface «

In order to secure the strands and electrical lines arranged on the circumference of the tube against displacement, it is advantageous according to the invention if the tube has spacing profiles on its circumference that run parallel to the reinforcement elements. In this embodiment, the individual strands and the electrical lines are placed in the spaces between the profiles.

According to a further embodiment of the sole hose rope according to the invention, instead of the hose and / or dumbbell made of rubber or plastic, a flexible, use smooth or corrugated metal pipe. The use of such a metal pipe is particularly useful when the hose rope according to the invention is subjected to strong pressure loads.

The invention is explained in more detail using the exemplary embodiments shown in the accompanying drawings. Show it:

ψ Fig. 1 a cross section through an inventive hose rope,

Fig. 2 shows a cross section through a soleplate rope according to the invention with a hose profiled in the longitudinal direction.

The hose cable according to the invention consists of an inner one Hose 1 of any length made of flexible material, for example made of polyamide, which can be reinforced by a steel spiral can. Concentric to the longitudinal axis of the cable on the outside The circumference of the hose 1 are tension-resistant strands and electrical lines 2 are arranged parallel to them in the same plane. These tensile strands 2 can consist of wires, threads or bands made of metal, plastics or glass fibers and are how t also the electrical lines 3 »are wrapped around the hose 1 with the longest possible base length. The electrical lines 3 consist of one of an Oefleohtleiter 4, for example made of copper, surrounded plastic core 5 and are surrounded by an insulation layer 6, on the tensile strands 2 and the electrical lines 3, a wrapping 7 made of plastic film and / or a braiding with plastic wires is applied. This wrapping 7 is used to fix the tensile strands 2 and the electrical lines 3. The outer jacket of the hose cable according to the invention is made of a smooth plastic
