TUNNELLING MACHINE Russian patent published in 2013 - IPC E21D9/10 

FIELD: mining.

SUBSTANCE: tunnelling machine includes a frame with caterpillar trucks, a tray, an actuating element with a telescope, a conveyor, a buffer device, and a control panel, which are fixed on it. With that, the machine frame is provided with a telescopic pushing device with a power cylinder and a buffer with a support cylinder and brackets for fixation of support beams with holes for anchor bolts and an installation place of anchor posts into the mine working roof. Extension value of an extensible part of the pushing device is divisible by the value of telescope of the actuating element and mine working support pitch. The control panel of the telescopic pushing device is combined with the machine control panel and interconnected with the machine operation. Besides, the machine buffer devices can be equipped with a telescopic part and combined along the machine frame axis in the pusher housing with an axial partition wall. The telescopic pushing device can be made in the form of telescopic cylinders using support beams with holes for anchoring to mine working ground, thus compensating the divergence of planes in support places of the machine caterpillar trucks and its support beams to the mine working ground.

EFFECT: enlarging scope of application of tunnelling machines with caterpillar movement as to inclination angles of the mine working; improving operating reliability of the machine and its mobility and compactness.
