Problems solved by technology

By means of this program mode, it is particularly tiresome when using the cutting triangles that are retained by the boring machines known in the prior art, and the section rounding (Profilrundungen) on the section edge, because the rock can easily from such remaining cross-sectional areas, they either have to be removed by separating means or pose a considerable risk

Embodiment Construction

[0017] exist figure 1 In , the roadheader is marked by 1 and has a traveling mechanism 2. The carriage is here configured as a carriage mechanism. A cutting body 5 is mounted on the cutting arm 3 , which can be adjusted vertically along the double arrow 4 by means of a corresponding adjusting device, the cutting body 5 being driven rotatably about an axis of rotation 6 .

[0018] Behind the cutting body 5 there are provided a cutting roller 8 which can be positioned on the top plate 7 and a cutting roller 10 which can be positioned on the bottom plate 9 . Here the cutting rollers 8 and 10 are fixed to a pivot arm 11 or 12 which is pivotable relative to the cutting arm 3 about an axis 13 or 14 . The hydraulic cylinders 15 and 16 each function as a pivot drive. Each of the two cutting rollers 8 and 10 is coupled to a single drive 17 or 18 respectively.

[0019] figure 1 Also depicted is a traction device 19 which extends in the longitudinal direction of the machine as far b...

Abstract

Disclosed is an advancing machine (1) comprising a driving gear (2) and a cutting boom (3) or frame. The cutting boom (3) or frame supports at least two rotating cutting heads (5), the axes of rotation (6) of which extend in the direction of advancement or enclose an acute angle along with the direction of advancement and jointly define a cutting profile having a certain width (a). The cutting boom (3) or frame further supports two cutting rollers (8, 10) which are disposed substantially parallel behind the cutting heads (5) and can be placed on the floor (9) or the roof (7). Both cutting rollers (8, 10) have final sections (25) that can be deployed to the width (a) of the profile in order to form a substantially rectangular cutting profile.

Description

technical field [0001] The invention relates to a boring machine (Vortriebsmaschine) with a traveling mechanism (Fahrwerk) and a cutting arm (Schneidausleger) or frame, wherein the cutting arm or frame supports at least two rotating cutting heads and two cutting rollers, at least The axes of rotation of the two rotary cutting heads extend in the direction of penetration or at an acute angle (spitzen Winkel) to the direction of penetration, and the at least two rotary cutting heads together define a cutting section with a profile width, two The cutting rollers are arranged approximately parallel and behind the cutting head and can be positioned on the bottom plate (Sohle) or on the top plate (Firste). Background technique [0002] Road boring machines with a cutting motor whose axis of rotation extends in or at an acute angle to the direction of driving are generally denoted "Marietta Bohrers", wherein the cutting unit comprises two or more rotating cutting heads. The two cu...
