Abstract

A sweeping brush (1) comprises a shaft (2) and radially oriented sweeping hoses (5) whose free ends (8) are closed by a plug (9) joined to the inner wall (10) of the hose.

Description

Die Erfindung betrifft eine Kehrbürste mit von einer Rotationswelle radial abstehenden, aus elastischem Material ausgebildeten Kehrschläuchen, die je ein zur Verbindung mit der Rotationswelle vorgesehenes erstes Ende und ein zum Abkehren vorgesehenes, von der Rotationswelle distanziertes zweites Ende aufweisen.The invention relates to a sweeping brush with radially projecting from a rotary shaft formed of elastic material sweeping hoses, each having a provided for connection to the rotary shaft first end and provided for sweeping, distant from the rotary shaft second end.

Aus AT 353 820 oder DE 1 254 121 ist eine Kehrbürste mit elastischen Kehrschläuchen bekannt. Diese sind auf Zapfen befestigt, welche von einer Rotationswelle der Kehrbürste radial abstehen. Im Inneren jedes Kehrschlauches ist ein als Federkörper ausgebildetes Versteifungsteil angeordnet, dass mit der Rotationswelle verbunden ist. Der Federkörper erstreckt sich ca. über ein Drittel der Länge des Kehrschlauches.Out AT 353 820 or DE 1 254 121 is a sweeping brush with elastic sweeping hoses known. These are mounted on pins which project radially from a rotary shaft of the sweeping brush. In the interior of each sweeping hose, a stiffening part designed as a spring body is arranged, which is connected to the rotary shaft. The spring body extends approximately over a third of the length of the sweeping tube.

Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung einer Kehrbürste der gattungsgemäßen Art, mit der durch Einsatz einfachster technischer Mittel eine Erhöhung der Verschleißfestigkeit erzielt wird.The object of the present invention is now to provide a sweeping brush of the generic type, with an increased wear resistance is achieved by using the simplest technical means.

Erfindungsgemäß wird diese Aufgabe mit einer Kehrbürste der eingangs genannten Art durch die im Kennzeichen von Anspruch 1 angeführten Merkmale gelöst.According to the invention this object is achieved by a sweeping brush of the type mentioned by the features cited in the characterizing part of claim 1.

Durch diese Ausbildung können die an ihren Enden besonders stark beanspruchten Kehrschläuche ohne großen Arbeits- und Konstruktionsaufwand verstärkt werden. Mithilfe dieser kostengünstigen Lösung wird die Lebensdauer der gesamten Kehrbürste erhöht, also verkürzen sich Nachrüstarbeiten und Standzeiten, die Serviceintervalle werden entsprechend länger. Auch gestaltet sich die nachträgliche Ausstattung bereits bestehender Kehrbürsten bzw. -schläuche mit Pfropfen finanziell und technisch als äußerst günstig. Weitere Vorteile und Ausbildungen der Erfindung ergeben sich aus den weiteren Ansprüchen und der Zeichnung.With this design, the particularly stressed at their ends sweeping can be reinforced without much effort and design effort. This cost-effective solution will extend the life increases the entire sweeping brush, so shorten retrofitting and service life, the service intervals are correspondingly longer. Also, the subsequent equipment already existing sweeping brushes or hoses with grafting financially and technically designed as extremely low. Further advantages and embodiments of the invention will become apparent from the other claims and the drawings.

Im folgenden wird die Erfindung anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher beschrieben.In the following the invention will be described in more detail with reference to embodiments shown in the drawing.

Es zeigen:

Fig. 1
eine Seitenansicht einer Kehrbürste mit Kehrschläuchen und
Fig. 2
eine Draufsicht auf einen Kehrschlauch.
Show it:
Fig. 1
a side view of a sweeping brush with sweeping hoses and
Fig. 2
a plan view of a sweeping tube.

Eine in Fig. 1 nur teilweise im Querschnitt dargestellte Kehrbürste 1 zum Abkehren eines Gleises besteht im wesentlichen aus einer zylinderförmigen, vorzugsweise hohl ausgeführten Rotationswelle 2. Diese ist um eine horizontale Achse 3 rotierbar ausgebildet und weist eine Vielzahl von radial abstehenden Zapfen 4 auf. Jeder dieser an der Rotationswelle 2 angeschweißte oder angeschraubte Zapfen 4 dient zur Aufnahme eines elastischen Kehrschlauches 5. Jeder auf einen Zapfen 4 aufgesteckte Kehrschlauch 5 ist an seinem ersten Ende 6 mittels einer Befestigungsvorrichtung 7 am Zapfen 4 kraftschlüssig befestigt. Besonders vorteilhaft erweist sich eine Ausbildung, bei der die Befestigungsvorrichtung 7 als Schlauchklemme ausgeführt ist. Ein von der Rotationswelle 2 distanziertes zweites Ende 8 jedes Kehrschlauches 5 ist mit einem Pfropfen 9 verschlossen. Dieser ist mit einer Innenwand 10 des Kehrschlauches 5 durch Verkleben oder Vulkanisation verbunden. Die Länge l des Pfropfens 9 beträgt vorzugsweise 100 bis 150 mm, er kann aus dem selben Material wie der Kehrschlauch 5 aber auch aus Hartgummi bestehen.A sweeping brush 1, shown only partially in cross-section in FIG. 1 for sweeping a track, consists essentially of a cylindrical, preferably hollow, rotating shaft 2. This is rotatable about a horizontal axis 3 and has a plurality of radially projecting pins 4. Each of these on the rotary shaft 2 welded or screwed pin 4 serves to receive an elastic sweeping tube 5. Each plugged on a pin 4 sweeping tube 5 is fixed at its first end 6 by means of a fastening device 7 on the pin 4 non-positively. Particularly advantageous is an embodiment in which the fastening device 7 is designed as a hose clamp. A second end 8 of each sweeping tube 5 that is distanced from the rotary shaft 2 is closed with a plug 9. This is connected to an inner wall 10 of the sweeping tube 5 by gluing or vulcanization. The length l of the plug 9 is preferably 100 to 150 mm, it may be made the same material as the sweeping tube 5 but also made of hard rubber.

Wie auch in Fig. 2 zu erkennen ist, weist der Pfropfen 9 Drahteinlagen 11 auf. Diese dienen zur Verstärkung des Pfropfens 9 und verlaufen in dessen Längsrichtung.As can also be seen in FIG. 2, the plug 9 has wire inserts 11. These serve to reinforce the plug 9 and extend in its longitudinal direction.
