Description

Annular float for delivery hoses

The invention relates to an annular buoyancy body for delivery hoses used on bodies of water, with the semicircular divided body in a jacket made of polymer material that surrounds it on all sides and a core made of foam plastic

There are known buoyancy bodies which envelop the hose in one piece and which have the disadvantage that if the buoyancy body or the hose is damaged or destroyed, it is not possible to replace one of the parts. Multi-part buoyancy in the form of half-shells siirid known. But these have, compared to the one-piece design, a number of other disadvantages au ^ "This ^L leraente are generally prepared by ausse. si. zone β clamps, bands or the like held together to form ring-shaped bodies. The external fastening elements can be easily damaged, which often leads to the loss of entire floating bodies. The previously known embodiments of these elements must either be made of flexible parts or be mounted on the hose at certain intervals in order to allow a certain flexural strength of the hose a loss of their ability to swim. In addition, these elements are very sensitive to damage »

In another embodiment, rigid half-cups are used used, which are hulten at a distance with elastic intermediate parts, so that a great mobility of the hose arises "

Finally, from the disclosure document 2 004 007 a float known for hoses, which essentially '" borrowed the structure as it was outlined at the beginning is «This float also has disadvantages in terms of attachment to the hose, because it A number of additional measures are required that can be damaged by prolonged use, so the body must be replaced by additional rings to be held around the hose "

The object of the invention is to provide a buoyancy body of the, at the beginning uuirlssenen kind of creating the disadvantageo avoids the above prior art and is easy to assemble, long service life and good adaptability on the conveying hose »The solution to this task is, according to the invention, that the dividing surfaces of the half-rings have gel connections that are sufficiently far from the outer diameter? removed are, the dividing surfaces so inclined to each other are that 2 rings that are connected to one another on one side can gape so far that an assembly is made possible on the hose and that the ring, seen in cross section, is in the non-saving state in the central zone has a deep, radially aligned ring groove on the inside

The ring elements should be without any bias with each other Touch to be placed on the hose. The V-shaped inner ring groove closes when the conveyor hose is bent and thereby limits the possible angle of inclination of the hose »The angle formed by the ring groove therefore depends on the size of the ring and the required mobility of the hose from · It should be ensured that the rings in each phase of the hose in each other Stay in contact without the fore tube buckling »

This enables deformation in a V-shaped ring groove the material in the area of the base of the hanging groove must be matched to the requirements and to design this zone as a flexible joint »This means that the stress on the material is proportionate kept low "

Preferably, the jacket made of glass fiber reinforced polyester resin is "that is resistant to sea water, the ring core is made of hard, closed-cell-Eiaterial that have _v drolysebeständigkeit a relatively massive large © strength and H at low density" to that of the sheath is to take precautions in material selection, that elastic deformability of the whole body is still possible · This ensures that no significant amounts of water can penetrate even if the casing of the ring parts is damaged. The end faces of the ring-shaped body have a conicity so that when the annular groove is closed by axial loading or when the hose is bent in, the conicity of the end faces of the annular surfaces is still so large that the end faces lie flat on top of one another.

The inner wall surface of the ring must be conical towards both end faces in the axial direction of the ring or be crowned widened «This means that the ring in its normal position only has a small Ring zone on the hose that is sufficient to to keep its position centric

When the ring groove is clamped together on one side, this conicity or crown should be retained to the extent that that it adapts to the inner curve of the bent hose the required buoyancy force and the distance from End stops on the hose, between which the rings are arranged in contact with each other

To simplify the attachment of the ring parts The dividing lugs of the half-rings on the hose should be designed as joints, with the joint brackets be arranged on both sides of the innermiut, so that full flexibility in the area of the joints the inner groove is guaranteed in the axial direction. The joint straps are made in one piece with special reinforcement made from the material of the jacket

The figure shows in Fig. 1 the cross section through half of an annular tube buoyancy element with a fiberglass reinforced plastic outer skin 1, the possible Hartschauin filling 2, the elastic acting Ring groove 3, which is adapted to the possible hose bend Inner contour 4 and the precisely defined conicity of the ends 5 »that when the hose is bent smooth overlapping of the individual end faces enables «

Fig. 2, a view of two half-shells with their hinge joints 6 are connected on one side, the bodies being conical at this hinge point are 7 »so that two unilaterally connected Clamps can be opened so far that in this case an assembly on the hose and adjoining Vei-bindtm the opposite hinge points possible 1st.

Fig. 3 shows a sectional view of the bent hose with max. Preformed floating elements. From this it can be seen at 8 that an unhindered deformation is also possible in the area of the hinge parts is.
