Abstract
Description
Die Erfindung gehärt zu der Bautechnik, im einzelnen zu den Bodendurchschlagmaschinen (BDSM) oder wie sie auch genannte werden IP-Raketen.The invention hardened to the building technology, in detail to the bottom punch machines (BDSM) or as they are also called become IP missiles.
Diese Maschinen finden bei der Verlegung von Röhren und Leitungen in dem Boden eine breite Verwendung. Sie schließen dabei den eigentlichen Durchschlagmechanismus, nämlich einen Druckluftantrieb, der sich in einem stabilen zylindrischen Gehäuse mit einer Hartmetallspitze vorne befindet, ein. Der Druckluftantrieb stellt dabei eine massive metallene Kolbenstange dar, die durch die Energie der Druckluft vor- und rücklaufende Bewegung ausführt. Die Druckluft gelangt von dem Kompressor, der sich an dem Ort, an dem die Erdarbeiten durchgeführt werden, befindet, zu dem Durchschlagmechanismus durch den Druckluftschlauch. Der Druckluftschlauch wird dabei fest an dem hinteren Teil des Gehäuses des Durchschlagmechanismus befestigt und hinter ihm her in den Tunnel, der von ihm durchgeschlagen wird, gezogen. Die Steuerung solcher Maschinen (die Befehle „Start" und „Stop") erfolgt durch einen Operator, durch die Zufuhr bzw. das Stappen der Zufuhr vom Druckluft.These machines are used when laying roar and pipes in the ground are widely used. You close it the actual punch mechanism, namely a compressed air drive, which is in a stable cylindrical housing with a hard metal tip located at the front. The compressed air drive represents a massive one metal piston rod represented by the energy of the compressed air forward and backward Movement. The Compressed air comes from the compressor, which is in the place where the earthworks are carried out to the punch mechanism through the compressed air hose. The compressed air hose is firmly attached to the rear part of the housing Punch mechanism attached and after him into the tunnel, which he is punched through. The control of such Machines (the commands "Start" and "stop") done by an operator, by feeding or stacking the supply of compressed air.
Unter der Wirkung der mächtigen Schläge des metallenen Kolbenstocks geht der Durchschlagmechanismus wie eine Rakete in den Boden hinein und zieht den Druckluftschlauch hinter sich her.Under the action of the powerful Blows of the The punch mechanism goes like a metal piston rod Rocket into the ground and pull the compressed air hose behind yourself.
Ein ernsthafter Mangel solcher BDSM ist, dass es unmöglich ist, ihre Bewegung unter der Erde zu kontrollieren. Diese Kontrolle ist insbesondere deswegen notwendig, weil, wenn sich auf der Bewegungslinie des Durchschlagmechanismus unterirdische Hohlräume („Löcher") befinden, der Durchschlagmechanismus einfach in ein solches Loch fällt und es praktisch unmöglich ist, ihn wieder da herauszuholen, da der Druckluftschlauch in solchen Fällen einfach reißt.A serious lack of such BDSM is that it is impossible is to control their movement underground. This control is particularly necessary because when on the line of movement of the punch mechanism are underground cavities ("holes"), the punch mechanism just falls into such a hole and it practically impossible is to get him out of there again, because the compressed air hose in such Cases easy tears.
Um diesen Verlust des Durchschlagmechanismus in unterirdischen Hohlräumen auszuschließen ist eine ständige Kontrolle seiner Bewegung in dem Boden notwendig. Es gelingt aber nicht, die Geschwindigkeit der Bewegung des Durchschlagmechanismus direkt zu messen, da er stark vibriert und die an ihm befestigten elektronischen Gerätschaften zum Ausfallen bringt. Der Autor schlägt hier vor eine mittelbare Kontrolle, aufgrund der Geschwindigkeit des Luftdruckschlauches, der hinter dem Durchschlagmechanismus her in den Tunnel, der durchgeschlagen wird, gezogen wird, durchzuführen. Anhand der Veränderung der Geschwindigkeit des Schlauches, und folglich auch des Durchschlagmechanismus, kann man darüber urteilen, ob er sich einem unterirdischen Hohlraum oder einem Hindernis (z.B. einem großen Stein) nähert. Beim Annähern an einen unterirdischen Hohlraum verringert sich in der Regel die Dichte des Erdbodens, was zu einem Anwachsen der Geschwindigkeit der Bewegung des Durchschlagmechanismus führt. Selbst wenn sich die Richte des Erdbodens nicht verringert (was höchst unwahrscheinlich ist), vergrößert sich die Geschwindigkeit bei dem Eintreten des Kopfteils des Durchschlagmechanismus in den Hohlraum aufgrund der Verringerung des Frontalwiderstandes innerhalb eines kurzen Zeitraumes erheblich.To this loss of the punch mechanism in underground cavities excluded is a constant Control of its movement in the ground is necessary. But it works not the speed of movement of the punch mechanism to measure directly because it vibrates strongly and the attached to it electronic equipment for Failure brings. The author strikes here an indirect control, due to the speed of the Air pressure hose, which comes in after the punch mechanism the tunnel that is cut through is to be pulled. Based on change the speed of the hose, and consequently the breakdown mechanism, one can about it judge whether it is an underground cavity or an obstacle (e.g. a large one Stone) is approaching. When approaching to an underground cavity is usually reduced Density of the soil, causing an increase in speed the movement of the punch mechanism. Even if the judge of the earth is not diminished (which is highly unlikely) increases the speed at which the head of the punch mechanism enters into the cavity due to the reduction in frontal resistance significantly within a short period of time.
In dem Fall, wenn sich auf dem Weg des Durchschlagmechanismus ein unüberwindbares Hindernis auftaucht, fallt seine Geschwindigkeit augenblicklich (innerhalb weniger Sekundenbruchteile) auf Null zurück. Auch in diesem Fall ist es notwendig, die Maschine zu stoppen.In the case when on the way the breakthrough mechanism shows an insurmountable obstacle, its speed drops instantly (within a fraction of a second) back to zero. In this case too, it is necessary to stop the machine.
Die entsprechende Lösung ist in den Ansprüchen l bis 4 beschrieben.The appropriate solution is in the claims 1 to 4 described.
Zur Verwirklichung des vorgeschlagenen Verfahrens erfordern die heute bereits existierenden Bodendurchschlagmaschinen, die ein Durchschlagmechanismus, der ein Gehäuse, z.B. in zylindrischer Form, mit einer Hartmetallspitze vorne, sowie ein sich innerhalb des Gehäuses befindendes, z.B. pneumatisches, Antieb, hat, eine Einrichtung für die Energiezufuhr zu dem Antrieb, die an das Gehäuse angeschlossen ist und sich hinter dem Durchschlagmechanismus her in den Tunnel, der durchgeschlagen wird, bewegt, z.B. ein druckluftzuführenden Schlauch, der mit einem seinen Ende an dem genannten Gehäuse befestigt. ist sowie eine Einrichtung zur Steuerung der Energiezuführ zu dem genannten Durchschlagmechanismus, z.B. der Druckluft von dem Kompressor einschließen, Ergänzungen. Das Wesen der vorgeschlagenen Ergänzung besteht darin, dass zusätzlich eine von dem Autor ausgearbeitete Kontrolleinrichtung für die Bewegung der BDSM benutzt wird, die von dem Durchschlagmechanismus abgesondert ist und sich an dem Ost, an dem die Erdarbeiten durchgeführt werden, befindet. Die entsprechenden Verbesserungen, die eine Verwirklichung des vorgeschlagenen Verfahrens ermöglichen, sind in den Merkmalen der Patentansprüche 5 bis 9 beschrieben.To implement the proposed method require the bottom punch machines that already exist today, which is a puncture mechanism comprising a housing, e.g. in cylindrical form, with a hard metal tip at the front, as well as one inside the housing, e.g. pneumatic, drive, has a device for power supply to the drive that is attached to the housing connected and after the punch mechanism into the tunnel being cut, e.g. a compressed air supply hose, the one end attached to said housing. is as well as a Device for controlling the supply of energy to said breakdown mechanism, e.g. include the compressed air from the compressor, supplements. The essence of the proposed Supplement exists in that in addition a control device for the movement of the BDSM is used which is secreted by the punch mechanism and is on the east, where the earthworks are carried out, located. The corresponding improvements that a realization enable the proposed method are in the features of claims 5 to 9 described.
