Abstract

FIELD: mechanical engineering. SUBSTANCE: power hinge connecting successively arranged feed hydraulic jacks includes head 3 with spherical surfaces 4 and 5 and cylindrical recess 6. Head 3 is secured to end of rod 8 and has bypass channel 7. Spherical surface 4 of head 3 rests on bushing 9 installed in bottom 10 of neighboring hydraulic jack 11, and spherical surface 5 rests on surface of removable lock 12 to ensure transmission of feed force with possibility of turning of neighboring hydraulic jacks relative to one another. Installed between cylindrical recess in bottom 10 and recess 6 for radial and axial displacement is sealing unit. The latter has ring 14 with outer spherical surface, radial seal 15, ring 16 with inner spherical surface, distance ring 17, thrust bushing 18, thrust ring 19 and end to presence of gaps H in course of operation. Two diametrically opposite recesses are made in side surface to provide installation of ring 16 on the side of end face seal 20. EFFECT: higher reliability of power hinge in operation of stoping machine on seams with intricate hypsometry and exclusion of leakage of working fluid. 4 cl, 4 dwg
