Description
Auf einem Schlitten geführte Gesteinsbohrmaschine mit Umsetzvorrichtung mittels Sperrades und unter dem Druck der Halteschrauben durch Reibung gegen Verdrehung gehaltenen Sperrkranzes, bei der der Bohrerhalter mit Bajonettverschluß versehen ist Ges@einsbohrmaschin.en in Verbindung mit einem Spindelvorschubschlitten, auf Dreifußgestell oder einer ähnlichen Vorrichtung montiert, sind bekannt und zum Bohnen von Schußlöchern vielfach verwendet. Bei Bohrungen in lassigem, zerklüftetem Gestein tritt nun häufig ein Verklemmen der Gesteinsbohrer ixt den Lassen auf, welches sich besonders bei den vorerwähnten schweren Maschinenausführungen oft empfindlich.geltend macht. Es sind zwar Vorrichtungen zum Freimachen des festgeklemmten Bohrers bekannt, die in der Weise wirken, da.ß durch Freiheben des Sperrkranzes die Maschine ohne Umsatz weiterarbeitet, bis der Bohrer wieder frei wird und die Drehung neuerlich eingeschaltet werden kann. Derartige Maschinen werden aber nur für sechs- oder achtkantigen Bohrstahl verwendet.Rock drilling machine guided on a slide with relocating device by means of ratchet wheel and under the pressure of the retaining screws by friction against rotation held locking ring, in which the drill holder is provided with a bayonet lock is Ges@einsbohrmaschin.en in connection with a spindle feed slide Mounted tripods or a similar device are known and used for beans widely used by gunshot holes. When drilling in loose, fissured rock there is now often a jamming of the rock drill ixt the Lassen, which is often sensitive, especially with the heavy machine designs mentioned above power. Although there are known devices for releasing the jammed drill, which act in such a way that, by lifting the locking ring free, the machine can be operated without Sales continue to work until the drill is free again and the rotation again can be switched on. Such machines are only for hexagonal or octagonal Used drill steel.
An Maschinen, bei denen der Gesteinsbohrer mittels eines Bajonettverschlusses in dem Bohrfutter bzw. Bohrerhalter befestigt ist, macht ein Verklemmen des Bohrers, welcher hierdurch an seinem weiteren Drehungsvermögen verhindert wird, ein umständliches Auseinandernehmen der ganzen Maschine erforderlich, da es anders unmöglich ist, den Bajonettverschluß zu lösen, die Maschine zurückzuziehen und den Bohrer für weitere Arbeit wieder frei zu machen.On machines where the rock drill is by means of a bayonet lock is fixed in the drill chuck or drill holder, causes the drill to jam, which is thereby prevented from its further turning ability, a cumbersome one The whole machine has to be dismantled, otherwise it is impossible loosen the bayonet lock, withdraw the machine and the drill for more To make work free again.
Die vorliegende Erfindung beseitigt die beschriebenen Mängel durch eine Vorrichtung, welche es ermöglicht, den festgeklemmten Gesteinsbohrer von der Maschine ohne Schwierigkeit und großen Zeitverlust zu entkuppeln.The present invention overcomes the deficiencies described a device which makes it possible to remove the jammed rock drill from the The machine can be uncoupled without difficulty and loss of time.
Die beiliegende Zeichnung veranschaulicht in den Abb. r bis 3 den Gegenstand der Erfindung und zeigt eine Entkupplungsvorrichtung, mit deren Hilfe es möglich ist, den Bajonettverschluß auch bei durch Festklemmen an der Drehung verhinderten Bohrern in einfacher Weise und zeitsparend zu lösen.The accompanying drawing illustrates in Figs. R to 3 the Subject of the invention and shows a decoupling device with the help of which it is possible to lock the bayonet lock also by clamping it on the rotation prevented drills to solve in a simple and time-saving manner.
Abb. r zeigt eine auf einem Spindelvorschubschlitten aufgebaute schwere Gesteinsbohrmaschine, in: welcher ein Gesteinsbohrer an seinem Einsteckende e durch die beiden Flügeld des Bajonettverschlusses im Bohrfutter c bzw. Bohrerhalter b gehalten, und bei der Drehung mitgenommen wird. Der zwischen dem Zylinderdeckel_g gelagerte Sperrkranz a ist so ausgebildet, da:ß er nach einem geringen Nachlassen der beiden Spannschrauben! mit Hilfe eines Hakenschlüseels und Nuten oder Löchern am Sperradumfange (s. Abb. z) gedreht werden kann. Während des normalen Betriebes wird der Sperrkranz a infolge der durch die beiden festgezogenen Spannschrauben! hervorgerufenen Reibung zwischen dem Zylinderdeckel g und dem Zwischendeckel/ gehalten und an einer Drehung verhindert, wodurch in bekannter Weise durch die Klinken des Sperrkolbens der Umsatz des Schlagkolbens erzielt wird.Fig. R shows a heavy weight mounted on a spindle feed slide Rock drilling machine, in: which a rock drill at its insertion end e the two wings of the bayonet lock in the drill chuck c or drill holder b held, and is taken when turning. The between the cylinder cover_g The bearing ratchet a is designed in such a way that: ß it after a slight slackening of the two tensioning screws! with the help of a hook wrench and grooves or holes can be turned on the ratchet wheel (see Fig. z). During normal operation the locking collar a becomes due to the tightening of the two tightening screws! caused friction between the cylinder cover g and the intermediate cover / held and prevented from rotating, whereby in a known manner by the pawls of the Locking piston the conversion of the percussion piston is achieved.
Tritt nun, ein Festklemmen des Bohrers während der Bohrarbeit und damit ein Stillstand des Bohnerumsatzes .ein:, so wird die Luftzufuhr, wie bekannt, abgesperrt, die beiden Spannschrauben! um ein geringes gelüftet, so daß sich der Sperrkranz drehen )aßt. Darauf werden beim Sperrkram a und am Schlüsselansatz des Bohnerhalters c die Schlüssel angesetzt, wodurch nach geringem Drehen um wenige Grade die Flügeld des Bohrereinrsteckendes e durch die entsprechende Öffnung des Bohrfutters c gebracht werden können und der Bohrer nach einfachem Zurückziehen der Maschine mit Hilfe der Vorschubspindel von der Maschine gelöst werden kann.Now occurs, a jamming of the drill during the Drilling work and thus a standstill in floor polishing .ein :, so the air supply, as known, locked, the two tensioning screws! lifted a little, so that the locking ring rotates) ate. Thereupon the bulky stuff a and the key approach of the floor polisher c the key is attached, which after a slight turn of a few Grade the wing of the Bohreinrsteckendes e through the corresponding opening of the Drill chuck c can be brought and the drill bit after simply retracting it the machine can be detached from the machine with the aid of the feed spindle.
Zur besseren Sicherung des Sperrkranzesa gegen Drehung während des normalen Betriebes kann auch noch ein Arretierstift h vorgesehen werden, welcher im Bedarfsfalle durch einfaches Zurückziehen den Sperrkranz zur Drehung freigibt.To better secure the locking ring against rotation during the During normal operation, a locking pin h can also be provided, which if necessary, releases the locking ring for rotation by simply pulling it back.
