Abstract: A tunnel driving machine includes an elongated machine frame having a central large frame portion accommodating a tunnel tool driving gearing and the associated driving motors and a forwardly extending and rearwardly extending tubular frame portion. The forwardly extending portion accommodates the main shaft for the forward driving tool and it is supported on front bracing in a manner permitting its longitudinal shifting movement relative to the bracing. A rearwardly extending tubular portion is supported in rear bracing which permits a longitudinal shifting movement. In addition to the front and rear bracing, there is a front support and a rear support for the tubular frame which may be selectively engaged with the tunnel wall during the times at which the front and rear bracing are removed from tunnel-wall engagement and shifted longitudinally. The construction includes driving motors connected between the main frame and the front bracing and main bracing and the rear bracing for facilitating advancing movement of each bracing element within the tunnel during those times at which the frame is supported on the front and rear supports.

Abstract: A DEVICE FOR CLAMPING A DRIVING OR DRILLING MACHINE IN RELATION TO A SURROUNDING SHAFT OR TUNNEL WALL INCLUDES ONE OR MORE CLAWS ARRANGES AT AT LEAST TWO LONGITUDINALLY SPACED LOCATIONS AND CONNECTED TO THE DRILLING MACHINE BY SHORT LINK ELEMENTS. EACH LINK ELEMENT IS PROVIDED AT ITS ONE END TO THE DRILLING MACHINE AND PIVOTED IN A UNIVERSAL MANNER TO THE CLAW AT ITS OPPOSITE END. TWO LONGITUDINALLY SPACED CLAW ELEMENTS ARE CONNECTED TOGETHER BY MEANS OF A FLUID PISTON AND CYLINDER CONNECTION WHICH EXTENDS THEREBETWEEN. THE LINK CONNECTION AND THE FLUID PISTON AND CYLINDER CONNECTION TO EACH JAW IS SUCH THAT WHEN THE FLUID PISTON AND CYLINDER APPLIES SUBSTANTIALLY DIRECTED AXIAL FORCE IN ONE DIRECTION THE CLAWS ARE DISENGAGED FROM THE WALL AND WHEN IT APPLIES AND AXIAL FORCE IN AN OPPOSITE DIRECTION THE CLAWS ARE ENGAGED WITH THE WALL. THE CONNECTION OF THE FLUID PISTON AND CYLINDER COMBINATION TO EACH CLAW IS AT A LOCATION OFFSET FROM THE CONNECTION OF THE LINK MEMBER WHICH CONNECTS THE CLAW TO THE DRILLING MACHINE.

Abstract: An apparatus for driving a tunnel shaft includes a driving machine which is supported within an auxiliary shaft which is pivotally mounted on a wheeled track car in a position such that it may be raised to the desired drilling or angle by an associated positioning mechanism. The drilling machine is mounted within the auxiliary shaft in a tubular support which may be clamped in position in respect to the auxiliary shaft or when the drilling progresses clamped to the drilled tunnel shaft walls. The drilling tool is mounted in front of the driving motor in a manner such that it can be extended or retracted as desired. An advancing stroke mechanism carried on a frame supporting the auxiliary shaft is arranged to engage a tubular structure supporting the driving motor and advance it outwardly into the wall structure being drilled. The advanced tubular support structure is supported in its extended position by additionally supplied cylindrical supporting and carrying elements which are placed between it and the mounting base therefor on the under carriage as the tunnel is progressively formed. The structure is locked in each incremental advance position by transversely movable hydraulic wedge elements which are positioned behind support cams defined on the previously applied supporting structures until another support structure of a length equivalent to the advance is added behind them. A tunnel shaft is drilled from the bottom to the top by first forming a cavern at the bottom of the intended shaft and moving the drilling apparatus into position within the cavern. Thereafter the auxiliary tunnel shaft is raised to an elevation corresponding to the angle at which the tunnel is to be driven and the drilling tool is extended to form an initial drilling cut while its driving motor is supported within a tubular member located within the auxiliary shaft. After an initial cut is made the drilling member together with its driving motor is advanced outwardly and clamped against the wall of the tunnel which has been drilled at the exterior of the auxiliary shaft.
