FIELD: mining.SUBSTANCE: unit consists of a working element, a supporting unit, at least one hydraulic cylinder and locking devices. A supporting unit is made of front and tail parts, between which a hydraulic cylinder is installed, which is connected on one side to the tail part of the supporting unit and on the other side to the working element. Guides combined with longitudinal slots of the other part are mounted into each part of the supporting unit. In guides of the tail part there are holes for fixation of parts of the supporting unit with locking devices. Above the supporting unit there installed are additional guides with holes, which are aligned with longitudinal slots of the working element and rigidly attached to the front part of the supporting unit. The locking devices are located between the front part of the supporting unit and the working element and made in the form of rods connected to each other with eye lugs with a hydraulic cylinder and installed so that they can be moved in pipes mounted into the working element and the front part of the supporting unit.EFFECT: simpler design, easier manufacture, assembly and installation directly in an output mine working.7 cl, 4 dwg |
