Abstract

A closure and rectification mechanism for mine shield supports that has gap closure plates between adjacent shield units and plates that are attached so that they can be pushed to the deck, start shield, and debris shield of the shield unit supported by coaxial guide tubes on the sides of the roof and of the debris of the shield unit, in which the limiting stops of the gap closure plates are pressed against the side wall of the Adjacent shield unit, characterized by the fact that in the direction of the axes of symmetry of the coaxial guide tubes (10 and 11) that slide one inside the other and that belong to each plate (5) is arranged a push rod (18), one end of which is particulate with the piston rod (21) of the hydraulic rectifier cylinder (19), rotatably fixed to the inner wall of the shield unit and the other e End to the limit stop (5) of the gap closing plate by means of unions (13a or 17).
