Abstract

Un bouclier expansible, de préférence constitué sous forme d'un bouclier à couteaux et destiné surtout au creusement de galeries souterraines dans des exploitations minières. Le bouclier expansible comprend des segments de cadre (6) de forme arquée qui s'appuient par l'intermédiaire de vérins hydrauliques (8) sur des segments de pied (7) qui sont accouplés mutuellement par l'intermédiaire d'une membrure de sole (13). Entre la membrure de sole et les segments de pied sont incorporés des dispositifs à coins (22) constituant des dispositifs d'écartement, et se présentant de préférence sous la forme de liaisons à élément de serrage et anneau-ressort connues en soi, au moyen desquels les segments de pied peuvent etre déplacés en direction des paroi latérales et en sens contraire.An expandable shield, preferably constituted in the form of a knife shield and intended especially for the digging of underground galleries in mining operations. The expandable shield comprises frame segments (6) of arcuate shape which are supported by means of hydraulic cylinders (8) on foot segments (7) which are mutually coupled by means of a sole member (13). Between the sole member and the foot segments are incorporated wedge devices (22) constituting spacers, and preferably in the form of clamping element and spring ring connections known per se, by means from which the foot segments can be moved in the direction of the side walls and in the opposite direction.
