Embodiment
Describe exemplary embodiments of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1, shown in Figure 2, base of the present utility model; A kind of damping device of mine excavator electrical control cubicles is by base 1, four guiders and four compositions such as polyurethane damping device of dress between spring shock-proof device 2, base and the excavator platform 20, the square frame shape steel construction of described base 1 for being welded with channel-section steel, the spring shock-proof device is arranged in the base 1 symmetrically and evenly, base 1 is connected with spring shock-proof device 2 bolts, shown in Figure 3, be the spring shock-proof device; Spring shock-proof device 2 is connected with connecting plate 3 bolts, welding when connecting plate 3 assembles at the scene with excavator platform 20, and the electrical control cubicles of excavator is connected with base 1 usefulness bolt.
Shown in Figure 4, be base polyurethane damping device; Base polyurethane damping device 4 comprises holder 401, following polyurethane piece 402, goes up polyurethane piece 403, bearing 404, backing plate 405, bolt 406, nut 407 and packing ring 408; Described holder 401 is welded together with the excavator platform field, bearing 404 welds together with base 1, bearing 404 is upper and lower respectively a polyurethane piece, following polyurethane piece is placed on the holder, and contact with top bearing 404, but be not stressed, so that play cushioning effect simultaneously with spring shock-proof device 2.Because the polyurethane piece is softer, on last polyurethane piece 403, placed a backing plate 405 (being equivalent to the effect of large washer), and with bolt 406, nut 407 and packing ring 408 with holder 401, following polyurethane piece 402, go up polyurethane piece 403 and backing plate 405 is fixed on the bearing 404.
Shown in Figure 5, be guider; Guider 5 is made of overcoat 501 and interior cover 502.Overcoat 501 is on-the-spot welded together with base 1, and interior cover 502 scenes are welded on the excavator platform 20, and interior cover 502 is inserted in the overcoat 501.When excavating vibrations taking place, electrical control cubicles and base can only be along the track vertical tremors, and guider play the guiding role.
