Description

Steuerventil für einen kombinierten Rammhammer und Pfahlzieher Die vorliegende Erfindung betrifft ein Steuerventil für einen kombinierten Rammhammer und Pfahlzieher. Bei Rammhämmern und Pfahlziehern ist es bekannt, die Umsteuerung durch das Treibmittel selbst zu bewirken. Der Arbeitskolben gibt, wie gleichfalls bekannt, bei jedem Hub entsprechende Öffnungen der Arbeitszylinderwand frei, die mit der Umsteuerungsvorrichtung, nämlich kleine Zv linder mit Steuerkolben, in Verbindung stäien.Control valve for a combined pile hammer and pile puller Die The present invention relates to a control valve for a combined pile hammer and stake pullers. It is known to reverse the direction of pile driving hammers and pile pullers caused by the propellant itself. The working piston gives, as well known, with each stroke corresponding openings in the working cylinder wall free, the with the reversing device, namely small cylinder with control piston, in connection stäien.

In deii beiden Steuerzylindern sind erfindungsgemäß in die Steuerzylinderräume .hineinragende Kugelventile enthalten, die unter dem Druck des Treibmittels stehen und die die Steuerkolben bis zur jeweiligen nächsten Umsteuerung halten. Bei einer Umsteuerung wird die Kugel durch die Steuerkolben zunächst zurückgedrängt, legt sich dann aber fest vor den Steuerkolben. Nachdem das Treibmittel die Umsteuerung be-,virkt hat, strömt es durch dieselben Öffnungen, durch die es in die Steuerzylinder eingeströmt ist, wieder in die AuspuAanäle ab. Die Kugeln verhindern dann das Zurücklaufen des Steuerkolbens. Die nächste Umsteuerung ist aber trotzdem sehr einfach und mit geringstem Kraftaufwand möglich, da nur der kleine Widerstand des erwähnten Kugelventils zu überwinden ist. Durch eine derartige Vorrichtung wird die Schlagzahl des Rammhammers ganz bedeutend heraufgesetzt.According to the invention, the two control cylinders are in the control cylinder spaces . Contain protruding ball valves which are under the pressure of the propellant and which hold the control piston until the next reversal. At a By reversing the direction, the ball is initially pushed back by the control piston but then firmly in front of the control piston. After the propellant reversed affected, it flows through the same openings through which it enters the control cylinder has flowed in, back into the exhaust ducts. The balls then prevent it from running back of the control piston. The next reversal is still very easy and with minimal effort possible, because only the small resistance of the ball valve mentioned is to be overcome. By means of such a device, the number of blows of the pile hammer raised quite significantly.

In der beiliegenden Zeichnung ist ein Ausführungsbeispiel der Vorrichtung dargestellt. In den Steuerzylindern i, za befinden sich die Steuerkolben 2, Za, die verbunden und je mit einer Steuerscheibe 3 versehen sind. In diese Steuerzylinder ragen nun dieKugelventile4,4a hinein. Das Kugelventil ist an den Verbindungskanal 5 angeschlossen, der entweder dauernd oder für die Zeiten zwischen den Umsteuerungen unter dem Druck des Treibmittels steht. Der Kanal steht demzufolge entweder mit der allgemeinen Treibstoffzuleitung oder mit dem Zylinderraum des Rammhammers selbst in Verbindung. Die Eintrittsöffnungen des Treibmittels für die Umsteuerung sind die Kanäle 6, 6a. Der Auspuff findet durch die Kanäle 7, ja statt.In the accompanying drawing is an embodiment of the device shown. The control pistons 2, Za, which are connected and each provided with a control disk 3. In this control cylinder the ball valves 4,4a now protrude into it. The ball valve is on the connecting channel 5 connected, either continuously or for the times between reversals is under the pressure of the propellant. The channel is therefore either with the general fuel supply line or with the cylinder chamber of the pile hammer itself in connection. The inlet openings of the propellant for the reversal are the channels 6, 6a. The exhaust takes place through ducts 7, yes.
