The invention relates to earth-compacting equipment intended for earth compaction under pipeline at replacement of its insulation coating, this is performed at design marks of pipeline in trench mostly without termination of its operation. An earth-compacting mechanism includes main body (6), on which wing-like bodies (15, 16) are hinged with pads-compacters (20) fixed on those. On the upper part of the main body (6) installation elements (8, 9) are provided, those are intended for hinging the main body (6) to handle of working equipment of single-bucket excavator by means of quick-operation holder (10), intended for hinging excavator bucket. Mechanism for forced turn of wing-like bodies (15, 16) is arranged as hydro-cylinders (12), those are hinged to the upper part of the main body (6) and respective wing-like bodies (15, 16). /System of elements (25, 26, 30, 31, 32) for synchronization of turn of wing-like bodies (15, 16) is arranged as inclined con-rods - synchronizers (25, 26), those with the lower ends are hinged to respective wing-like bodies (15, 16), and with the upper ends (28, 29)–to common axle (30), that is installed in the main body (6) with possibility of straight motion. The mechanism has positioning equipment (38) that is intended for control of position of earth-compacting mechanism with respect to pipeline (5). |
