Description

Das Patent 853 735 ;bezieht sich auf eine abnehmbare hydraulische Setzvorrichtung zumSetzen mehrteiliger Grubenstempel, die allen Stempeln zwangsweise eine gleiche Vorlast verleiht und auch den Spannkeil mit gleicher Kraft anschlagen kann. Die Setzvorrichtung kann an jedem beliebigen Stempel angesetzt werden.Patent 853,735 relates to a detachable hydraulic system Setting device for setting multi-part pit punches that are compulsory for all punches gives the same preload and also attach the clamping wedge with the same force can. The setting device can be attached to any punch.

Ferner wird nach dem Hauptpatent vorgeschlagen, in einem Druckzylinder einen Kolben zum Erzeugen der Setzspannung gegen den Druck einer Feder wirken zu lassen. Diese Feder ist Ermüdungserscheinungen unterworfen und könnte damit die konstante Vorlast der Stempel ändern.It is also proposed according to the main patent, in a printing cylinder a piston to generate the setting tension against the pressure of a spring to act permit. This spring is subject to signs of fatigue and could therefore die change constant preload of the punches.

Um dies zu vermeiden, wird vorgeschlagen, die Feder durch ein gasförmiges Kissen zu ergänzen. Vorteilhaft wird es sein, die in der Grube unter Tage vorhandene und in einem Streb auch mit gleichem Druck vorhandene Preßluft zu benutzen, um einen entsprechenden pneumatischen Gegendruck zu erzeugen.To avoid this, it is suggested that the spring be replaced by a gas Complement pillow. It will be advantageous to use what is underground in the pit and to use compressed air available in a longwall with the same pressure in order to to generate appropriate pneumatic counter pressure.

In konstruktiver Weiterentwicklung wird ferner vorgeschlagen, die Kolbenstange des Druckzylinders der Setzvorrichtung zu verlängern, -und zwar in solchem Maße, daß die abnehmbare Setzvorrichtung wahlweise als Vorschubvorrichtung für Fördermittel bzw. deren Antriebe zu benutzen ist. Die Anwendungsmöglichkeit dieser Vorrichtung wird damit wesentlich erweitert. Damit wird aber auch neben einer Verbilligung des Betriebes eine Vereinfachung bzw. Erleichterung für den Bergmann geschaffen, der ein ihm bekanntes Gerät dann für die verschiedensten Zwecke benutzen kann.In a constructive further development it is also proposed that To extend the piston rod of the pressure cylinder of the setting device, in to such an extent that the removable setting device can optionally be used as a feed device is to be used for funding or their drives. The application possibility this device is thus significantly expanded. But that also means next to one Cheaper operation a simplification or relief for the miner created, who then use a device known to him for various purposes can.

Ein Ausführungsbeispiel des Erfindungsgedankens ist in der Zeichnung schematisch dargestellt. Die Abbildung zeigt eine Ansicht der Setzvorrichtung mit verlängerter Kolbenstange in Anwendung als Rückvorrichtung eines Förderbandes.An embodiment of the inventive concept is shown in the drawing shown schematically. The figure shows a view of the setting device with Extended piston rod used as a rear device for a conveyor belt.

Gemäß der Abbildung ist die Setzvorrichtung 4 als Vorschubvorrichtung für ein Förderband 6 dargestellt. Dabei kann z. B. die Kolbenstange 7 der Setzvorrichtung durch geeignete Verlängerungsteile 8 den jeweiligen Verhältnissen angepaßt werden. Die Ausbildung des Kopfes der Kolbenstange 7 oder der Verlängerungsteile, 8 kann derart ausgeführt sein, daß ein abnehmbarer Haken dort angebracht werden kann.According to the figure, the setting device 4 is a feed device shown for a conveyor belt 6. It can, for. B. the piston rod 7 of the setting device be adapted to the respective conditions by suitable extension parts 8. The formation of the head of the piston rod 7 or the extension parts 8 can be designed so that a removable hook can be attached there.

Der große Vorteil einer solchen Setzvorrichtung liegt darin, daß dem Bergmann ein einziges Gerät für verschiedene im Streb auszuführende Arbeiten in die Hand gegeben ist; er wird also schneller lernen, mit dem Gerät richtig umzugehen, als wenn er lernen muß, mehrere verschiedene Geräte für die einzelnen Arbeitsgänge zu bedienen. Außerdem wird ihm die Arbeit schneller und leichter von der Hand gehen, zumal das Gerät auch eine handliche Größe und ein geringes Gewicht besitzt.The great advantage of such a setting device is that the Bergmann uses a single device for various work to be carried out on the face in the hand is given; so he will learn faster to use the device correctly, as if he had to learn several different devices for the individual work steps to use. In addition, the work will be faster and easier for him, especially since the device has a handy size and low weight.
