Heading Machine

Abstract

In a heading machine ( 1 ) including a track chain running gear, a cutter arm ( 3 ) pivotally fixed to a machine frame and comprising rotatably drivable cutting tools ( 4 ), a fresh-air supply for supplying fresh air to the working face, and an exhaust means for evacuating exhaust air and dust from the working face, the heading machine ( 1 ) further comprises at least one anchor drilling and setting device ( 5 ) disposed behind the cutting tools ( 4 ) and at least one working platform ( 11 ) disposed at least partially laterally outside the anchor drilling and setting device ( 5 ), wherein at least one air duct of the fresh-air supply and/or the exhaust means is led through below the at least one working platform ( 11 ) and/or laterally led around the working platform ( 11 ).

1 . A heading machine ( 1 ) including a track chain running gear, a cutter arm ( 3 ) pivotally fixed to a machine frame and comprising rotatably drivable cutting tools ( 4 ), a fresh-air supply for supplying fresh air to the working face, and an exhaust means for evacuating exhaust air and dust from the working face, characterized in that the heading machine ( 1 ) further comprises at least one anchor drilling and setting device ( 5 ) disposed behind the cutting tools ( 4 ) and at least one working platform ( 11 ) disposed at least partially laterally outside the anchor drilling and setting device ( 5 ), and that at least one air duct of the fresh-air supply and/or the exhaust means is led through below the at least one working platform ( 11 ) and/or laterally led around the working platform ( 11 ). 
     
     
         2 . A heading machine according to  claim 1 , characterized in that an upper duct wall of the at least one air duct forms at least a portion of the working platform ( 11 ). 
     
     
         3 . A heading machine according to  claim 1 , characterized in that the air duct in the portion led through below the working platform ( 11 ) or led laterally around the working platform ( 11 ) is designed as a connection box profile ( 13 ) whose dimension in a direction transverse to the longitudinal central plane of the machine is preferably smaller than in the vertical direction. 
     
     
         4 . A heading machine according to  claim 1 , characterized in that the anchor drilling and setting device ( 5 ) is pivotally fixed about an axis extending in the longitudinal direction of the machine, and a portion of the air duct, on its side facing the anchor drilling and setting device ( 5 ), comprises a wall ( 14 ) that is pivotable and/or displaceable into the interior of the duct. 
     
     
         5 . A heading machine according to  claim 1 , characterized in that the air duct comprises a region adjoining, in the direction of the working face, the portion led through and/or around, which region extends upwardly and widens in terms of width, including a first aspiration and/or outlet opening ( 6 ,  16 ), which is oriented to the working face. 
     
     
         6 . A heading machine according to  claim 1 , characterized in that, on the inner wall of the air duct, a further air duct opens with a second aspiration opening ( 15 ), which is disposed below the first aspiration opening ( 6 ) and at a smaller distance from the longitudinal central plane of the machine than the first aspiration opening ( 6 ). 
     
     
         7 . A heading machine according to  claim 1 , characterized in that the air duct comprises an obliquely upwardly extending region ( 7 ) adjoining the led-through portion in the direction toward the machine end and connected to an exhaust conduit. 
     
     
         8 . A heading machine according to  claim 1 , characterized in that at least one anchor drilling and setting device ( 5 ) including a working platform ( 11 ) disposed laterally outside the anchor drilling and setting device ( 5 ) is each provided on both sides of the longitudinal central plane of the machine, and an air duct of the fresh-air supply and the exhaust means, respectively, is each led through below the two working platforms ( 11 ). 
     
     
         9 . A heading machine according to  claims 1 , characterized in that the working platform ( 11 ) together with the air duct are arranged to be inwardly displaceable so as to achieve a smaller machine width.
