DE202016007371U1 - Clamp profile hose line with corrugated sheathing of the clamping profile - Google Patents

Abstract

Flexible hose assembly consisting of one or more helically wound, overlapping wound material webs. The overlapping edges of the material web (s) (2.3) are clamped with a helical thread-wound coiled metal clamping profile (2.2). The hose is characterized in that the metal clamping profile in addition from a view of the sheathing profile in the transverse direction annular or helically corrugated sheathing profile, in which Wellenberg (1.4) and wave trough (1.2) connect, is coated on the outside.

Description

The technical basis of this hose construction, for which protective rights are registered, is in "FG Wieck's German Illustrated Business Magazine", in volume 27 of 1862 on page 212 under "Smaller Communications / Technological" to find:
"Hoses by JF Jordan. Hose manufacturer in Fürth. We draw our attention to the hoses invented by the named manufacturer. They are made of double leather without seam, inside and outside with spirals of tinned iron wire, so that they can withstand the greatest pressure and are especially suitable for bringing water. As regards their durability, z. For example, some time ago the Engelhardt factory in Fürth had 200 large hoses à. 9 feet and 300 pieces shorter à. 4 feet, and it has not yet become a bit damaged. Such hoses are currently not manufactured anywhere. "

Based on this basic construction, flexible tubing with external coil was patented for AE Chernack in the USA in 1943 ( United States Patent 2,340,794 ). They consist of one or more helically coiled overlapping wound material webs in which the wall material is clamped around an insert wire with an external metal clamping profile wound spirally wound in a helical thread. They are referred to as clamping profile hoses. The clamping profile connects the individual wall tracks and is also the skeleton of the hose line.

If one pulls a clamping profile hose described above over a surface, the clamping profile causes an abrasion protection, which prevents damage to the wall material. Although the clamping profile protects the hose itself, it can cause damage where it comes into contact with other materials or objects. Therefore, the clamping profile as in ua DE 10 2005 008 240 A1 (Krischik / Buschmeier) described, encased.

• 1. Beim Führen heißer Medien in Klemmprofilschläuchen mit nicht ummanteltem Klemmprofil besteht kein Schutz gegen Verbrennungen der Haut, wenn der Schlauch zufällig berührt wird. Die bisher bekannten Klemmprofil-Ummantelungsprofile erwärmen sich durch den innigen Kontakt mit dem Klemmprofil und durch ihre kleine Oberfläche nach einiger Betriebszeit fast auf die Temperatur im Inneren des Schlauches und bieten deshalb nur geringen Verbrennungsschutz.
• 2. Derzeit bekannte Ummantelungsprofile lassen sich nachträglich nur an den Schlauchenden gegen Ablösung sichern. Wird das Ummantelungsprofil im Verlauf des Schlauches aufgrund rauer Betriebsbedingungen abgelöst oder beschädigt, ist keine Reparatur möglich und der Schlauch wird unbrauchbar.
• 3. Bei allen bisher bekannten Ummantelungsprofilen stellt deren Formstabilität einen Schwachpunkt aufgrund zu schwacher Klemmwirkung dar.
• 4. Bisher bekannte Ummantelungen haben einen relativ hohen Gleitreibwert beim Ziehen des Schlauches über den Boden. Wenn die Schlauchleitung über unebene Flächen gezogen wird kann sich sowohl das nicht ummantelte als auch das ummantelte Klemmprofil leicht an Unebenheiten verhaken.

For hoses without clamping profile sheathing and hoses with the previously known clamping profile sheaths proves to be a disadvantage:

• 1. When carrying hot media in clip hoses with non-jacketed clamp profile, there is no protection against skin burns if the hose is accidentally touched. Due to the intimate contact with the clamping profile and due to its small surface, the hitherto known clamping profile sheathing profiles, after some operating time, almost heat up to the temperature inside the hose and therefore offer only low combustion protection.
• 2. Currently known sheathing profiles can be subsequently secured only at the hose ends against detachment. If the sheathing profile is detached or damaged in the course of the hose due to harsh operating conditions, no repair is possible and the hose becomes unusable.
• 3. In all previously known sheathing profiles whose dimensional stability represents a weak point due to weak clamping effect.
• 4. Hitherto known sheaths have a relatively high Gleitreibwert when pulling the hose over the ground. If the tubing is pulled over uneven surfaces, both the unjacketed and shrouded clamp profiles can easily catch on bumps.

• 1. Wird die Schlauchleitungen zur Absaugung von Medien mit hohen Temperaturen eingesetzt, erwärmt sich auch das Klemmprofil. Da das Ummantelungsprofile an der Innenkante des Wellentales nur geringfüg, weil nur punktuell, direkten Kontakt mit dem Klemmprofil hat, kann das gewellte Ummantelungsprofil fast nur durch Strahlungswärme erhitzt werden, was zu einer reduzierten Erwärmung des Ummantelungsprofiles führt. Wegen der vergrößerten wärmeabgebenden Oberfläche des gewellten Ummantelungsprofiles gibt es vermehrt Wärme an die Umgebung ab, was zu einer insgesamt reduzierten Temperatur des Ummantelungsprofiles führt.
• 2. Das Ummantelungsprofil ist gewellt. Es bietet die Möglichkeit einen Sicherungsring überall dort, wo es erfoderlich ist, in ein Wellental einzudrücken. Dadurch kann man Reparaturen an der Profilummantelung ohne nennenswerten Aufwand durchführen, z. B. wenn Beschädigungen aufgetreten sind. Weil man die Ummantelung an jedem beliebigen Schlauchabschnitt beginnen und enden lassen kann, besteht außerdem die Möglichkeit, innerhalb einer Schlauchleitung verschiedene Ummantelungsmaterialien einzusetzen um eventuellen technische Erfordernissen zu entsprechen. Es können auch Teilbereiche von der Ummantelung ausgenommen werden, wenn dies erforderlich ist. Auch lassen sich zwischen Ummantelung und Klemmprofil (auch nachträglich) Leitungen (z. B. zur Stromversorgung, zu Steuerungszwecken, für Zuleitungen von Messfühlern etc.) einlegen, die evtl. im Schlauchverlauf mitgeführt werden sollen.
• 3. Die Wellung des Ummantelungsprofiles ist ring- oder schraubenförmig quer angebracht. Es entsteht dadurch eine Federwirkung und die Rückstellkraft verstärkt sich erheblich. Dadurch entsteht eine deutlich bessere Formstabilität als alle bisher bekannten Ummantelungen.
• 4. Das Ummantelungspofil weist quere Wellenberge und quere Wellentäler auf. Wird das Klemmprofil des Schlauches damit ummantelt, befinden sich die Wellenberge und Wellentäler in Längsrichtung des Schlauches. Durch die Längsrillen kann der Schlauch leicht gezogen werden, ohne dass er sich am Untergrund festhakt. Die hier beschriebene Schauchkonstruktion hat dementsprechend in Längsrichtung einen geringeren Gleitreibwert als alle bisher bekannten Konstruktionen.

Hoses with the clamping profile casing described below eliminate the disadvantages listed above as follows:

• 1. If the hose lines are used for the extraction of high-temperature media, the clamping profile also heats up. Since the sheathing profiles on the inner edge of the wave trough only slightly, because only selectively, has direct contact with the clamping profile, the corrugated sheathing profile can be heated almost only by radiant heat, resulting in a reduced heating of the sheathing profile. Because of the increased heat dissipating surface of the corrugated sheath profile, there is increased heat to the environment, resulting in an overall reduced temperature of the sheathing profile.
• 2. The casing profile is corrugated. It offers the possibility to press a circlip into a trough wherever it is required. As a result, you can carry out repairs to the profile casing without significant effort, z. B. if damage has occurred. Because it is possible to start and finish the sheathing on any hose section, it is also possible to use different sheathing materials within a hose line to meet any technical requirements. Partial areas may also be excluded from the shell if necessary. In addition, cables (eg for power supply, for control purposes, for supply lines of sensors, etc.) can be inserted between the sheathing and the clamping profile (possibly also in the hose path).
• 3. The corrugation of the sheathing profile is transversely or helically mounted. It creates a spring action and the Restoring force increases considerably. This results in a significantly better dimensional stability than all previously known sheaths.
• 4. The sheathing profile has transverse peaks and transverse troughs. If the clamping profile of the hose is thus sheathed, the wave crests and wave troughs are located in the longitudinal direction of the hose. Through the longitudinal grooves of the hose can be easily pulled without hooking it to the ground. The chimney construction described here accordingly has a lower Gleitreibwert in the longitudinal direction than all previously known constructions.
