Die Erfindung bezieht sich auf eine Vorrichtung zur Geräuschdämpfung einer pneumatischen Gesteinsbohrmaschine mit mehreren Antrieben oder einer Gruppe von Gesteinsbohrmaschinen, bei der mindestens eine an die Gesteinsbohrmaschine angeschlossene Abluftleitung am anderen Ende mit einem Behälter zum Expandieren der Abluft verbunden ist.The invention relates to a device for dampening the noise of a pneumatic rock drilling machine with several drives or a group of rock drilling machines with at least one on the rock drilling machine connected exhaust line at the other end with a container to Expanding the exhaust air is connected.
Vorrichtungen der vorbeschriebenen Art bewirken zwar eine Verminderung des auftretenden Lärms im Bereich der hörbaren Frequenzen, aber nicht in einem ausreichenden Maß, denn in einem gewöhnlichen Ausdehnungsgefäß kann sich die Luft nur unkontrolliert ausdehnen. Es Verbleibt somit eine Lärmbelästigung des Bedienungspersonals, die über das medizinisch Vertretbare hinausgeht Von der vorgenannten, in der GB-PS 76 884 beschriebenen Ausführungsform werden auch die von der Druckluft mitgeführten Verunreinigungen nicht so weitgehend ausgeschieden, daß nicht eineDevices of the type described above cause a reduction in the noise occurring in the Range of audible frequencies, but not to a sufficient extent, for in an ordinary one Expansion vessel, the air can only expand in an uncontrolled manner. There remains a noise nuisance of the Operating personnel who go beyond what is medically justifiable From the aforementioned in the GB-PS 76 884, the contaminants carried along by the compressed air are also used not so largely eliminated that not one
Verunreinigung der Atmungsluft des Bedienungspersonals bewirkt würde.Contamination of the operator's breathing air would be caused.
Vorliegende Erfindung hat sich eine weitere Verbesserung einer Vorrichtung zur Verminderung des von einer oder mehreren pneumatischen Steinbohrmaschinen verursachten Geräusches und der Luftverunreinigungen zur Aufgabe gesetztThe present invention has been a further improvement of an apparatus for reducing the one or more pneumatic stone drills caused noise and air pollution set to the task
Gemäß der Erfindung wird diese Aufgabe dadurch gelöst daß die Abluftleitungen von der Gestcnsbohrmaschine zu einer Sammelvorrichtung geführt sind, der ein Zyklon nachgeschaltet ist Die Aufgabe, das von dem Gesteinsbohrer bzw. den Gesteinsbohrern erzeugte Geräusch zu dämpfen, wird von dem Zyidon weit effektiver gelöst als vou den bekannten Vorrichtungen, da die Luft den Zyklon in Form eines Wirbels durchläuft dessen Kern durch die Abluftöffnung austritt Gleichzeitig scheidet der Zyklon alle in der Abluft anwesenden Verunreinigungen ab. An den Zyklon ist ein Behälter zum Auffangen der aus der Abluft abgeschiedenen Verunreinigungen angeschlossen.According to the invention, this object is achieved in that the exhaust air lines from the drilling machine are led to a collection device, which is followed by a cyclone To muffle the rock drill or the sound generated by the rock drill becomes far from the zyidon solved more effectively than the known devices, as the air passes through the cyclone in the form of a vortex, the core of which emerges through the exhaust opening at the same time the cyclone separates all impurities present in the exhaust air. There is a container on the cyclone connected to collect the impurities separated from the exhaust air.
Bei einer Vorrichtung für Gesteinsbohrmaschinen mit getrenntem Drehschlag- und Vorschubantrieb wird die Abluft des Drehschlagantriebs in einem Behälter an der Gesteinsbohrmaschine gesammelt an den eine Abluftleitung angeschlossen ist. Ein Teil der Abluft der Gesteinsbohrmaschine ist dabei mittels einer zusätzlichen Abluftleitung an einen Ejektor angeschlossen, mittels welchem die in dieser Leitung geführte Abluft in den Abluftstrom der Abluftleitung injizierbar ist Bei Vorrichtungen gemäß der Erfindung für Gesteinsbohrmaschinen mit vom Schlagantrieb getrenntem Rotationsantrieb ist die Luftaustrittsöffnung des Rotationsantriebs an die zusätzliche Abluftleitung angeschlossen. Eine Weiterbildung der Erfindung sieht vor, daß dem Luftaustrittskanal des Zyklons ein Filter nachgeschaltet ist.In a device for rock drilling machines with separate rotary percussion and feed drive, the Exhaust air from the rotary percussion drive is collected in a container on the rock drilling machine on an exhaust air line connected. Part of the exhaust air from the rock drilling machine is by means of an additional Exhaust air line connected to an ejector, by means of which the exhaust air guided in this line into the exhaust air flow of the exhaust air line can be injected in devices according to the invention for rock drilling machines With the rotary drive separated from the impact drive, the air outlet opening of the rotary drive is connected to the additional exhaust air line. A further development of the invention provides that a filter is connected downstream of the air outlet duct of the cyclone is.
Bei einer Gruppe von Gesteinsbohrmaschinen mit jeweils eigenem Drehschlag- und Vorschubantrieb sind die verschiedenen Antriebe der Ge.«teinsbohrmaschinen jeweils an eine gemeinsame Sammelleitung für die Abluft angeschlossen, die in die Sammelvorrichtung münden.In a group of rock drilling machines, each with its own rotary percussion and feed drive the various drives of the rock drilling machines each connected to a common collecting line for the exhaust air that enters the collecting device flow out.
Ein Ausführungsbeispiel einer erfindungsgemäßen Vorrichtung ist in der Zeichnung dargestellt.
Die Bohrmaschine 1 wird, von der Zuführvorrichtung 2 getragen, mit Hilfe des Zustellmotors 3 hin- und
hergehend bewegt. Zur Bohrmaschine 1 gehören ein Rotationsmotor und eine Schlagvorrichtung, die beide
ebenso wie auch der Zustellmotor 3 mit Druckluft betrieben werden. In Verbindung mit der Bohrmaschine
1 befindet sich ein Behälter 4. in v/elchen die Abluft vom
Rotationsmotor und von der Schlagvorrichtung geleitet wird. Die Abluft der Bohrmaschine 1 aus dem Behälter 4
sowie die Abluft des Zustellmotors 3 werden in einen gemeinsamen Abluftkanal oder -schlauch 5 geführt. In
diesem Fall sind die von mehreren Bohrmaschinen kommenden Abluftschläuche 5 mittels einer Sammelvorrichtung
6 vereinigt worden, die am Zyklon 7 angeschlossen ist, der an seinem unteren Ende einen
zum Sammeln der Verunreinigungen vorgesehenen BehälterS aufweist. Wenn sich die von den Bohrmaschinen
angesammelte Luft im Zyklon 7 ausdehnt, wird das von den Austrittstößen Verursachte Geräusch gedämpft.
Der effektive Zyklon scheidet alle in der Abluft anwesenden Verunreinigungen ab, und die gereinigte
Luft tritt durch den Kanal 9 aus, der noch bei Bedarf mit einem nachträglichen Filter versehen werden kann.
Neben dem Zyklon 7 besitzt bei der Erfindung dieAn embodiment of a device according to the invention is shown in the drawing.
The drilling machine 1, carried by the feed device 2, is moved back and forth with the aid of the feed motor 3. The drilling machine 1 includes a rotary motor and an impact device, both of which, like the feed motor 3, are operated with compressed air. In connection with the drill 1 there is a container 4. in which the exhaust air from the rotary motor and the impact device is conducted. The exhaust air from the drill 1 from the container 4 and the exhaust air from the feed motor 3 are fed into a common exhaust duct or hose 5. In this case, the exhaust hoses 5 coming from several drilling machines have been combined by means of a collecting device 6 which is connected to the cyclone 7, which has a container S at its lower end for collecting the impurities. When the air accumulated by the drills expands in the cyclone 7, the noise caused by the discharge blows is muffled. The effective cyclone separates all impurities present in the exhaust air, and the cleaned air exits through the duct 9, which can be provided with a subsequent filter if necessary.
In addition to the cyclone 7 has the invention
Sammelvorrichtung 6 eine wesentliche Bedeutung, welche Vorrichtung die von den Bohrmaschinen austretenden Luftströme sammelt und vereinigt. Die wichtige Bedeutung der Sammelvorrichtung 6 liegt darin, daß man sie als in bekannter Weise effektiv arbeitenden Ejektor ausbilden kann, dem ein Teil der Abluft durch die Kanäle oder Schläuche 10 hindurch durch eine effektive Düse 11 mit bekannter Gestalt zugeleitet wird. Auf diese Weise kann man einen Teil der Abluft dazu heranziehen, eine Saugwirkung für den restlichen Teil der Abluft zu erzeugen, und derCollecting device 6 is essential which device is used by the drills exiting air currents collects and unites. The important importance of the collecting device 6 lies in that you can train them as an ejector that works effectively in a known manner, which is part of the Exhaust air through the channels or hoses 10 through an effective nozzle 11 of known shape is forwarded. In this way you can use part of the exhaust air to create a suction effect for the to generate the remaining part of the exhaust air, and the
Gegendruck an den Austrittsöffnungen der Bohrmaschine geht herab. In dem in der Zeichnung dargestellten Fall ist die Abluft zum Ejektor durch den Schlauch 10 vom getrennten Rotationsmotor der Bohrmaschine bezogen worden, aber sie kann auch der Bohrmaschine selbst oder dem Zustellmotor in der Zuführvorrichtung entnommen werden.Counterpressure at the outlet openings of the drill goes down. In the one shown in the drawing The case is the exhaust air to the ejector through the hose 10 from the separate rotary motor of the drill but it can also be the drill itself or the feed motor in the feeder can be removed.
Es ist ferner der erfindungsgemäßen Vorrichtung eigen, daß die Bohrmaschine 1 an sich bei Bedarf bereits mit Schalldämpfzylinder, -behälter, -schläuchen usw. versehen werden kann.It is also peculiar to the device according to the invention that the drill 1 is already in place when required can be provided with silencing cylinders, tanks, hoses, etc.
