Abstract
Description
Die Erfindung betrifft die Schüssel einer Sandstreueinrichtung für Schienenfahrzeuge, insbesondere Straßenbahnen, die ein leicht ansteigendes Steigrohr und ein nach unten gerichtetes Fallrohr besitzt, wobei dem Steigrohr gegenüberliegend und in einem Abstand eine an einen Kompressor angeschlossene Bohrung als Sandstrahlrohr endet.The invention relates to the bowl of a sand spreader for rail vehicles, especially trams, the one a slightly rising riser and a downward one Downpipe has, with the riser opposite and at a distance one connected to a compressor Drilling as a sandblast pipe ends.
Aus der DE-GM 88 08 841 ist eine Sandstreueinrichtung bekannt, bei der bei gleichbleibendem Luftstrom aus dem Sandstrahlrohr durch eine Stellschraube der Querschnitt des Fallrohrs verän derbar ist. Es hat sich jedoch gezeigt, daß eine derartige Anordnung den gewünschten Erfolg, nämlich Drosselung des Sandaustritts, nicht ergab, so daß die einmal eingestellte und zu streuende Sandmenge durch eine derartige Abordnung nicht zu verändern ist.A sand spreading device is known from DE-GM 88 08 841, in the case of constant air flow from the sandblasting tube change the cross-section of the downpipe using a set screw is derbar. However, it has been shown that such Order the desired success, namely throttling the Sand outlet, not revealed, so that once set and amount of sand to be scattered by such a deposition cannot be changed.
Der Erfindung liegt die Aufgabe zugrunde, die Schüssel einer Sandstreueinrichtung so mit einer Führung der Luft vom Kompressor auszustatten, daß die auszutretende Sandmenge von der in das Steigrohr eingeblasenen Luft gesteuert wird.The invention has for its object the bowl one So sand spreading device with a guidance of the air from Equip compressor that the amount of sand to be discharged from the air blown into the riser pipe is controlled.
Nach der Erfindung wird diese Aufgabe dadurch gelöst, daß an die Bohrung ein das Steigrohr umgehender abgedeckter Kanal angeschlossen ist der mittels eines Rohres im Fallrohr endet und dessen Querschnitt verstellbar ist.According to the invention, this object is achieved in that the bore is a covered channel bypassing the riser pipe is connected which ends with a pipe in the downpipe and whose cross section is adjustable.
Die Erfindung ist nachstehend anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispiels näher erläutert.The invention is based on one in the drawing schematically illustrated embodiment explained in more detail.
Es zeigen:Show it:
Fig. 1 eine Draufsicht auf die Schüssel, Fig. 1 is a plan view of the bowl,
Fig. 2 einen Schnitt nach Linie II-II der Fig. 1, Fig. 2 shows a section according to line II-II of Fig. 1,
Fig. 3 einen Schnitt nach Linie III-III der Fig. 1. Fig. 3 is a section according to line III-III in FIG. 1.
Die mit dem Sandbehälter verbundene Schüssel 1 besitzt ein senkrecht nach unten gerichtetes Fallrohr 2, das über ein leicht abfallendes Steigrohr 3 an der tiefsten Stelle der Schüssel 1 endet. Dem Steigrohr 3 in einem Abstand gegenüber liegend endet eine als Sandstrahlrohr dienende und im Flansch 4 angeordnete Bohrung 5, die an einen Kompressor angeschlossen ist. Durch Bohrungen 6 und 7 und Ausfräsungen 8 und 9, die vom Sandbehälter 1a abgedeckt sind, wird ein Kanal 10 gebildet, der die Bohrung 5 unter Umgehung des Steigrohrs 3 mit dem Fallrohr 2 verbindet, wobei zur Überbrückung des Steigrohrs 3 in die Bohrung 7 ein bis in das Fallrohr 2 reichendes Rohr 11 eingesetzt ist, so daß die Luft aus dem Rohr 11 den Durchfluß des Sandes im Fallrohr 2 beschleunigt, die auszutretende Sand menge jedoch nicht beeinflußt. In einen Krümmer 12 des Kanals 10 greift eine den Querschnitt und damit dem Luftstrom ändernde Schraube 13 ein. The bowl 1 connected to the sand container has a down pipe 2 directed vertically downwards, which ends at the lowest point of the bowl 1 via a slightly sloping riser pipe 3 . Opposite the riser pipe 3 , a hole 5 serving as a sandblasting pipe and arranged in the flange 4 ends and is connected to a compressor. Through bores 6 and 7 and milled 8 and 9 , which are covered by the sand container 1 a, a channel 10 is formed, which connects the bore 5 bypassing the riser pipe 3 with the down pipe 2 , with the riser pipe 3 being bridged into the bore 7 a pipe 11 reaching into the down pipe 2 is inserted so that the air from the pipe 11 accelerates the flow of sand in the down pipe 2 , but does not affect the amount of sand to be discharged. A screw 13, which changes the cross section and thus the air flow, engages in an elbow 12 of the channel 10 .
Durch eine den Querschnitt der Bohrung 5 verändernde Stell schraube 14 kann die Menge der aus der Bohrung 5 ausströmenden Luft dosiert werden und damit die größte Menge des bei der jeweiligen Bahnverwaltung zu streuenden Sandes. Da diese Sandmenge für die Mehrzahl der einzelnen Strecken nicht erforderlich ist, kann dann für die jeweilige Strecke die hier erforderliche Sandmenge durch die Querschnittsänderung und damit Drosselung des Luftstroms im Kanal 10 mittels der Schraube 13 im Krümmer 12 eingestellt werden.By changing the cross section of the bore 5 adjusting screw 14 , the amount of air flowing out of the bore 5 can be metered and thus the largest amount of sand to be scattered in the respective railway administration. Since this amount of sand is not required for the majority of the individual sections, the amount of sand required here can then be set for the respective section by changing the cross-section and thus throttling the air flow in the duct 10 by means of the screw 13 in the manifold 12 .
