The specific embodiment
Shown in Fig. 1~7, a kind of fastening devices of mine excavator pressed on ring rail, the section of described pressed on ring rail 1 is T-shaped, be installed in below the revolving platform of excavator 2, between described pressed on ring rail 1 and the described revolving dial 2 installing plate 3 is set, with positioning boss 3-1, a T shape 1-1 and the described boss 3-1 of described pressed on ring rail 1 are close to described installing plate 3, and with bolt 6, nut 7, packing ring 9 described pressed on ring rail 1, installing plate 3, revolving dial 2 are tightened together in the inboard of described pressed on ring rail 1; The outside at described pressed on ring rail 1 tightens together described pressed on ring rail 1, installing plate 3, revolving dial 2 with socket head screw 4.
The arranged outside L-type lesser calorie sheet 5 of described installing plate 3 and described pressed on ring rail 1, described L-type lesser calorie sheet 5 heads are with crotch 5-1 (seeing Fig. 4), after screw 4 is tightened, described crotch 5-1 can snap in the hexagon socket head of described socket head screw 4, the another side point of described L-type lesser calorie sheet 5 is welded on the described installing plate 3, prevents screw loosening, drops out.
The inboard of described pressed on ring rail 1 arranges L-type and adjusts pad 8 (seeing Fig. 6), described L-type is adjusted pad 8 and is close to pressed on ring rail 1 on one side, another side is provided with the hole 8-1 with bolt 6 suits, and described hole 8-1 is sleeved on the bolt 6 and is close to the plane of nut 7, prevents that nut 7 rotates in the bolt 6 fastening processes.
