FIELD: mining industry, namely, devices for suspension of bridges with drilling equipment positioned on the bridge during drilling of deep mine shafts, primarily by means of drilling and exploding method. ^ SUBSTANCE: device for suspension of bridge during drilling of deep shafts includes pulleys, winches, each one of which is connected to bridge by rope in suspension system of pulleys by means of hydro-cylinder held on bridge, rod hollow of which is connected to rod hollows of other hydro-cylinders for evening out stretching of ropes, device is also provided with beams, positioned above the bridge, with rigid mounting thereof in the shaft and possible remounting with deepening of shaft, while each beam is provided with pulleys, circled by ropes of suspension system of pulleys. ^ EFFECT: decreased weight of bridge suspension ropes in system of pulleys due to decreased length of ropes, possible drilling of deep mine shafts, increased operation reliability of mining equipment. ^ 2 dwg |
