Embodiment Construction

[0033] figure 1 1 denotes a tunnel boring machine or mining machine according to claim 1 of the present invention, wherein a cutting roller 3 is attached to the boom 2, the cutting roller 3 being rotatable about a horizontal axis and having a perimeter arranged at the cutting roller 3 Multiple cutting tools on 4. The boom 2 is pivotable vertically in the direction of the double-headed arrow 5 so that the cutting tool can be moved on a not shown driving face. A removal tool for the excavated material is indicated at 6, by means of which the excavated material can be transferred to a conveying device extending in the longitudinal direction of the machine. The excavated material is conveyed by means of conveying means to the rear end 7 of the machine where it is transferred, for example, to stationary conveying means in the form of a belt conveyor or chain conveyor. The machine 1 also has a crawler unit 8 .

Abstract

In a tunneling or mining machine comprising a cutting tool (4) movable over a face and arranged on a boom (2) and a platform (10), said platform being able to move in the longitudinal direction of said machine Move in the direction and carry the tunnel roof support device, and the tunnel roof support device includes a support manipulator (13) or a support device (40) and a bolt-drilling and bolt-setting device (14), wherein the bolt - drilling and bolting - setting means (14) are secured to said movable platform (10) in a pivotable manner between a parking position and an operating position, and said support manipulator (13) or support The device (40) has a telescopic arm (16) fastened in a vertically pivotable manner to said movable platform (10), wherein said support manipulator (13) or support means (40) and said bolt-drilling and bolt-setting device (14) are fastened to said movable platform (10) at a predetermined fixed distance apart from each other and are able to communicate with said movable platform ( 10) Displacement together between a retracted position and a forwardly displaced position.

Description

technical field [0001] The invention relates to a tunneling or mining machine comprising a cutting tool movable on a heading face and arranged on a boom, and a platform movable in the longitudinal direction of the machine and carrying road support. Background technique [0002] Such a tunneling or mining machine is known from AT 507495 A1. [0003] When fixing and supporting tunneled roads, various types of fixing and road support devices are usually provided, wherein, depending on the structure of the rock, in addition to bolt-drilling and bolt-setting devices are also required for handling and Shotcrete manipulators or devices for positioning support frames or arch structures. Conventional tunneling or mining machines do not fully meet these requirements, since different types of road support devices cannot be arranged at suitable locations simultaneously and in a space-saving manner. For example, handling devices have been proposed for supporting elements, such as supp...
