Advance working or mining machine

Abstract

In an advance working or mining machine including a traveling mechanism, excavation tools movable over the mine face as well as roof bolt drilling and setting apparatus having associated operating platforms for the operation of the roof bolt drilling and setting apparatus, at least a part of laterally cantilevering platforms is each arranged to be pivotable and/or displaceable transversely to the longitudinal axis of the machine.

1 . An advance working or mining machine comprising: 
 a traveling mechanism;    excavation tools movable over a mine face;    roof bolt drilling and setting apparatus; and    an operating platform means associated with said roof bolt drilling and setting apparatus and provided for operation of said roof bolt drilling and setting apparatus, wherein    said operating platform means comprises a laterally cantilevering platform means having at least a part arranged to be at least one of pivotable and displaceable transversely to a longitudinal axis of said advance working or mining machine.    
   
   
       2 . An advance working or mining machine as set forth in  claim 1 , further comprising adjustment drive means constructed to press said laterally cantilevering platform means in an outwardly displaced or pivoted position against a side wall at an adjustable pressing pressure.  
   
   
       3 . An advance working or mining machine as set forth in  claim 1 , further comprising a machine frame, and wherein said operating platform means comprises a platform part rigidly connected with said machine frame, said platform part rigidly connected with said machine frame in top view being located within a contour spanned by a respectively broadest dimension in a region of said excavation tools and a respectively smallest width on a rear end of said machine frame.  
   
   
       4 . An advance working or mining machine as set forth in  claim 3 , wherein said laterally cantilevering platform means having at least a part arranged to be at least one of pivotable and displaceable transversely to the longitudinal axis of said advance working or mining machine is at least one of pivotable and displaceable into a position located within said contour.  
   
   
       5 . An advance working or mining machine as set forth in  claim 1 , further comprising 
 lateral edge means provided on said laterally cantilevering platform means having at least a part arranged to be at least one of pivotable and displaceable transversely to the longitudinal axis of said advance working or mining machine, and    at least one of runner means and lateral shield means provided on said lateral edge means.    
   
   
       6 . An advance working or mining machine as set forth in  claim 3 , wherein said laterally cantilevering platform means having at least a part arranged to be at least one of pivotable and displaceable transversely to the longitudinal axis of said advance working or mining machine is arranged in a manner respectively capable of being at least one of pivoted in and inserted below said platform part rigidly connected with said machine frame, in a vertical direction.  
   
   
       7 . An advance working or mining machine as set forth in  claim 2 , wherein said adjustment drive means are hydraulic adjustment drive means.  
   
   
       8 . An advance working or mining machine as set forth in  claim 2 , wherein said adjustment drive means are pneumatic adjustment drive means.
