Device serving as support and drilling aid for roadway driving in mining and tunnelling

摘要

The invention relates to a device serving as support and drilling aid for roadway driving in mining and tunnelling, having a multi-piece platform which is suspended preferably at varying height on several rail tracks via travelling crabs with lifting gear and has a rail guide for the base frame of a manipulator which is movable in the longitudinal direction and has a boom arranged on the slewing head, rotatable about a longitudinal axis, of a slewing mechanism attached to the base frame. A supporting framework, consisting of parallel girders and brackets fastened to them and preferably intended for simultaneously accommodating several caps of the roadway support, is linked to the tip of the boom by an operating joint provided with a swivel cylinder. According to the invention, provision is made here for the boom to be subdivided by means of operating joints with swivel cylinders into a base boom connected to the slewing head, a centre piece connected to the base boom, and an end piece consisting of several parts guided on one another, the working range of which is selected in such a way that the centre piece can be folded onto the base boom and the end piece can be folded onto the centre piece, in which arrangement the supporting framework, forming with its girders the carriage of a rotary-drilling machine, can be swung back onto the boom end piece by the swivel cylinder of its operating joint.
