Abstract

A rail-mounted deep mine cutter advances along a conveyer track supported by a bogey with rollers front and back either side of a pivot (15). The pivot is attached to the machine frame (16). The rollers have elastic dampening bushes and roller bearings that absorb the impulses caused by the coalface cutter (4). The roller frame incorporates dust and rock deflectors.

Description

Bei untertägigen Gewinnungsmaschinen ( I ) werden in der Regel sogenannte Rollkufen ( 1 ) eingesetzt, um die Gewinnungsmaschine kohlestoßseitig abzustützen. Dafür ist die Rollkufe ( 1 ) über die Achse ( 15 ) freipendelnd mit der kohlestoßseitigen Maschinenstütze ( 16 ) verbunden. Die Rollkufen ( 1 ) laufen auf einer an dem Förderer ( 2 ) angebrachten Fahrbahn ( 3 ).For underground mining machines ( I ) are usually so-called roller skates ( 1 ) used to support the extraction machine on the coal pile side. The roller skate ( 1 ) over the axis ( 15 ) oscillating with the machine support on the coal pile side ( 16 ) connected. The roller skids ( 1 ) run on one at the conveyor ( 2 ) attached roadway ( 3 ).

Mit zunehmender technischer Entwicklung sind diese Gewinnungsmaschinen in den letzten Jahren immer leistungsfähiger geworden, d.h. sowohl die installierte Antriebsleistung als auch das Maschinengewicht haben stetig zugenommen.With Increasing technical development are these extraction machines have become increasingly powerful in recent years, i.e. both the installed drive power as well as the machine weight steadily increased.

Dadurch bedingt wird die Flächenbelastung der Rollen und deren Lagerstellen bei gleichzeitig zunehmenden Marschgeschwindigkeiten der Maschinen immer größer. Immer häufiger kommt es zur Blockade der Rollen, die dann bei hohen Marschgeschwindigkeiten aufgrund der Reibung mit der Fahrbahn zu unzulässigen Temperaturen an den Reibungsflächen führt.Thereby the surface load of the Rolls and their bearings with increasing marching speeds of the machines getting bigger. always frequently the roles are blocked, which then occurs at high marching speeds due to friction with the road surface at inadmissible temperatures friction surfaces leads.

Bekannt ist die Lagerung der Rollen mittels Gleitbuchsen, welche ursächlich für das angeführte Problem sind. Der Einsatz leichtgängiger Wälzlager scheiterte bisher an den durch das Gewinnungsorgan ( 4 ) schlagartig eingebrachten Stoßbelastungen, die in kurzer Zeit zur Zerstörung der Wälzlager führten.It is known to store the rollers by means of sliding bushes, which are the cause of the problem mentioned. The use of smooth-running rolling bearings has so far failed due to the 4 ) Suddenly introduced shock loads, which quickly destroyed the rolling bearings.

Der Erfindung liegt deshalb die Aufgabe zugrunde, den zerstörungsfreien Einsatz von Wälzlagern in den Rollkufen ( 1 ) zu ermöglichen und ein sicheres Abrollen zu gewährleisten.The invention is therefore based on the object of the non-destructive use of rolling bearings in the roller skids ( 1 ) and to ensure a safe roll.

Beschreibungdescription

( II ) Die Rollen ( 5 ) sind mit der Rollkufe ( 1 ) über die Achsen ( 6 ) verbunden. Die Rollen ( 5 ) werden dabei mit den Wälzlagern ( 7 ) und der Dämpfungsbuchse ( 8 ) auf der Achse geführt und durch die Deckel ( 9,10 ) in Position gehalten. Der Deckel ( 9 ) mit der Dichtung (11 ) dient gleichzeitig der Abdichtung der Rolle ( 5 ). Über die Bohrung ( 12 ) mit der Verschlussschraube ( 13 ) wird die Rolle ( 5 ) mit Schmiermittel befüllt.( II ) The roles ( 5 ) are with the roller skate ( 1 ) about the axes ( 6 ) connected. The roles ( 5 ) with the roller bearings ( 7 ) and the damping bush ( 8th ) on the axis and through the cover ( 9 . 10 ) held in position. The lid ( 9 ) with the seal ( 11 ) also serves to seal the roller ( 5 ). About the hole ( 12 ) with the screw plug ( 13 ) the role ( 5 ) filled with lubricant.

Die durch die Gewinnungsorgane eingeleiteten Stoßbelastungen werden durch die elastische Dämpfungsbuchse ( 8 ) aufgefangen und die Wälzlager ( 7 ) somit geschützt. Zusätzlich ist die Rollkufe ( 1 ) beidseitig mit Abweisern (14 ) versehen, welche das Bergematerial von der Fahrbahn räumen. Zur Unterstützung des Abrollens der Rollen ( 5 ) sind diese zusätzlich profiliert.The shock loads introduced by the extraction organs are absorbed by the elastic damping bush ( 8th ) and the roller bearings ( 7 ) thus protected. In addition, the roller skate ( 1 ) with deflectors on both sides ( 14 ) which clear the recovery material from the road. To support the rolling of the rolls ( 5 ) these are additionally profiled.
