Abstract
The invention relates to a shield-type support frame for the mining industry, comprising two horizontal runners (50), two front guide rods (20), and two rear guide rods (30), which each are supported pivotally on the horizontal runner (50) by means of a front or rear swivel pin (5, 8). Each guide rod has two stringers (21, 31), which with the ends thereof protrude beyond a center bar (22, 32), which rigidly connects the stringers, as lower and upper fork joints. In order to minimize the risk of blockages of the guide rod when retracting the guide rod gear mechanism by means of design measures on the guide rod and/or on the horizontal runner, at least the center bars (22) of the front guide rods (20) with the fronts (25) thereof are disposed at a distance from the lower fork joints (23) of the front guide rods (20), while forming vertical debris pass-throughs (26), and/or the horizontal runners (50) are provided with oblique bottoms (53) for lateral debris removal. The invention also relates to the horizontal runners.
