Description

Die Erfindung bezieht sich auf Stempel für den Strebausbau und 1rezw#eckt, einen Stempel derart auszubilden, claß dieser nicht nur in einfacher Weise auf Länge eingestellt, verspannt und verkeilt werden kann, sondern auch bei entsprechendem Druck durch Spannungsglieder nachgiebig oder starr gestaltet und gelöst werden kann. Der Stempel nach der 'Erfindung besteht in der Hauptsache aus der Stempelsäule a, Stempelfuß (1, Umspannungsmuffe c, Stempelspindel e und Stempelkopf f. Das Rohr, die Stetnpelsäule cz, zeigt am oberen Einführungsende spiralförmig verlaufende Schraubengänge 6, die den Zweck haben, den Stempel auf Länge einzustellen, zu halten und als Mutter zu dienen.The invention relates to stamps for longwall mining and 1rezw # eckt to form a stamp such that this can not only be easily adjusted to length, clamped and wedged, but also made flexible or rigid and released with appropriate pressure by tension members can. The stamp according to the 'invention consists mainly of the stamp column a, stamp foot (1, Umspannungsmuffe c, stamp spindle e and stamp head f. The tube, the Stetnpelsäule cz, shows at the upper insertion end spiraling screw threads 6, which have the purpose of Adjust the punch to length, hold it and serve as a nut.

Die spiralförmig verlaufenden hänge I) sind direkt iin Rohr (AN). 3) verformt, eingewalzt oder eingepreßt, was zur leichteren Rauart führt. Diese spiralförmig verlaufenden Gänge 1) können jedoch anstatt im Rohr direkt in einer aufsteckbaren L'mspannungsmuffe c (Abb. i und 2) verlegt werden. 1 )er übrige Teil der Stempelsäule a ist glatt und zeigt am unteren -Aufsatzende den Stempelfuß d. Die Stempelspindel, Körper oder 1Zohr c nach der Erfindung hat in der ganzen Länge die gleichen spiralförmig verlaufenden Schraubengänge !), die den Zweck haben, den Stempel auf Länge einzustellen. vorzuspannen, zu halten und als Schraube zu dienen. Der Stempelkopf f am oberen Ende der Stempelspindel e zeigt eine drehbar gelagerte, auf einen Pilz g ruhende Kopfplatte h zwecks Aufnahme des Kopfholzes. Die Umspannungsmtlffe c mit innenliegenden Bremskugeln »i oder Bremsdübel ;i hat den Zweck, den Druckverlauf abzubremsen und zugleich al, Verstärkung des Stempels zu dienen. I )ie hrenlskugeln ni oder Bremsdübel )1 sind innerllalt) der Umspannungsmuffe keil- oder schraullenfö rlnig verlagert. mittels derer die Stempelspindel e in ihrer Prehbewegung gebremst, festgelegt und wieder gelöst werden kann. 1)i(! Formgebung der spiralförmig verlaufenden Scllratll)engätlge ist äußerstballig; dasgestattet.größereAl)bremsflächeli zu erreichen und für den rauben Grubenbetrieb besser geeignet zu sein. l)ie f Ierstellung ist aus 1Zollr oder Walzmaterial, iusl)csoudere für die Stempelspindel auch aus profiliertem Walzmaterial gedacht. Es 'kann ein- oder mehrg;illgig sein, kalt oder warm verformt. Die Steigung der spiralförmig verlaufenden Schraubengänge liegen all der Grenze der Selbsthemmung, um dadurch den Gebirgsdruck /' auf die Schraubengänge zu übertragen und nur das sich ergehende kleine Drehmoment al>zul>rcmsen. Die .Ausführungsbeispiele der Erfindung flach dell _1bb. i bis 3 beruhen iln Gegensatz zu den üblichen Stempeln darin, daß der auftretende Druck /' im Stempelkopf auf einer spiralförmig verlaufenden Schraubenlinie übertragen wird, Vorspannung zu- läßt und <las de, Druckes im I)rehsinile durch Kugeln. Rollen oder I@remsdül>eln mittel Keilen oder Schrauben erfolgt. 1)er Stempel wirkt starr oder nachgiebig, wobei er eilte runde, engum- schlungene Form behält und weniger I,austoffe er- f(-)rdert. The spiral slopes I) are directly in the pipe (AN). 3) deformed, rolled or pressed in, which leads to a lighter rough type. These spirally running corridors 1) can, however, be laid directly in a clip-on clamping sleeve c (Fig. I and 2) instead of in the pipe. 1) the rest of the stamp column a is smooth and shows the stamp foot d at the lower end of the attachment. The punch spindle, body or 1Zohr c according to the invention has the same helical screw threads over its entire length!), Which have the purpose of adjusting the punch to length. pretensioning, holding and serving as a screw. The punch head f at the upper end of the punch spindle e shows a rotatably mounted head plate h resting on a mushroom g for the purpose of receiving the head wood. The purpose of the Umspannungsmlffe c with internal brake balls »i or brake dowels; i is to slow down the pressure curve and at the same time serve to strengthen the ram. I) The rubber balls or brake dowels) 1 are displaced in the shape of a wedge or screw inside the clamping sleeve. by means of which the preheating movement of the punch spindle e can be braked, fixed and released again. 1) i (! The shape of the spiral-shaped scalp) engätlge is extremely convex; that allows to achieve a larger Al) braking surface and to be better suited for the robbery mining operations. l) The production is made of 1 inch or rolled material, iusl) csoudere for the punch spindle also made of profiled rolled material. It can be single or multiple, cold or hot deformed. The pitch of the helically running screw threads lies at the limit of the self-locking in order to transfer the rock pressure / 'to the screw threads and only allow the resulting small torque. The embodiment of the invention flat dell _1bb. i to 3 are based on the opposite of the usual Stamp in that the pressure occurring / 'im Stamp head on a spiral Helical line is transmitted, preload to- lets and <read de, Druckes im I) rehsinile by bullets. Rolls or I @ remsdül> eln medium Wedges or screws is done. 1) the stamp works rigid or yielding, in which case he hurried round, narrow retains its curved shape and less I, f (-) rdert.
