Abstract
The utility model discloses a water-proof and dust-proof device for a rotation center position of an excavator and belongs to the technical field of excavators. The water-proof and dust-proof device for the rotation center position of the excavator comprises a C-shaped seal plate I and a C-shaped seal plate II, a ring-shaped race and a rubber ring. A round hole and a U-shaped hole are respectively arranged at two ends of the seal plate I and the seal plate II, and openings of two ends of the seal plate I and the seal plate II are symmetrically spliced and correspond to each other. A groove is arranged in the race and matched with the seal plate II in terms of shape. Two round holes are respectively arranged at two ends of the groove. The seal plate II is arranged in the groove. The seal plate I, the seal plate II, the race and the rubber ring are fixed between a rotation center body of the excavator and a large baseplate of a rotation platform from top to bottom through connection bolts and gaskets. The water-proof and dust-proof device for the rotation center position of the excavator has the advantages of effectively preventing dust and rain from entering into a gear mesh place of a rotation system, protecting parts at the gear mesh place from being abraded and ensuring working efficiency and being beneficial for prolonging service life of the excavator, simple in structure, convenient to install and dismantle and easy to maintain.
Description
Technical field
The utility model relates to a kind of digger revolving center anti-dust water-proof device, belongs to the excavator technical field.
Background technology
Excavator center steering body is mainly used in the counterrotating top of excavator and is connected with oil circuit between the bottom, and the hub of center steering body is fixedly connected with the revolving dial of excavator, and its axle is fixedly connected with the lower vehicle frame of excavator.As shown in Figure 6, the large base plate of revolving dial is provided with a circular hole usually, and the hub of center steering body passes the connection revolving dial thus.But owing to having the gap between this hole and center steering body, during the rainy day, rainwater easily thus the gap and then affect lubricant effect along large base plate soffit inflow pivoting support and rotary motor pinion place; And the excavator operating mode is abominable, dust is more in the operating environment, some dusts or even the grains of sand also thus the gap enter to meshing zone of gears, not only pollute lubricant grease, affected lubricant effect, more seriously, some grains of sand that mix in the lubricant grease easily make gear surface produce wearing and tearing when gear meshes, even destroy geared parts, affect service life of a machine and operating efficiency.
Summary of the invention
For above-mentioned existing technical problem, the utility model provides a kind of digger revolving center anti-dust water-proof device, can effectively block rainwater and dust and enter rotary system gear engagement place.
The utility model is achieved through the following technical solutions for achieving the above object: a kind of digger revolving center anti-dust water-proof device comprises C shape shrouding I and shrouding II, annular seat ring and rubber ring; Shrouding I and shrouding II two ends are provided with a circular hole and a U-shaped hole respectively, and relative, the symmetrical splicing of both openings; Seat ring is provided with groove, and groove and shrouding II shape are coincide, and the groove two ends are respectively equipped with a circular hole; The shrouding II is inserted in the groove, and shrouding I, shrouding II, seat ring and rubber ring are fixed between digger revolving centerbody and the large base plate of revolving dial by connecting bolt and packing ring from top to bottom.
The beneficial effects of the utility model are: effectively block rainwater and dust and enter rotary system gear engagement place, protection gear engagement place component are not frayed, are conducive to prolong excavator application life; guarantee operating efficiency; simple in structure, and easy accessibility, be easy to safeguard.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 4, the utility model comprises C shape shrouding I 2 and shrouding II 3, annular seat ring 4 and rubber ring 5; Shrouding I and shrouding II 3 two ends are provided with a circular hole and a U-shaped hole respectively, and relative, the symmetrical splicing of both openings; Seat ring 4 is provided with groove 41, and groove 41 coincide with shrouding II 3 shapes, and groove 41 two ends are respectively equipped with a circular hole; Shrouding II 3 is inserted in the groove 41, and shrouding I 2, shrouding II 3, seat ring 4 and rubber ring 5 are fixed between digger revolving centerbody 7 and the large base plate 6 of revolving dial by connecting bolt and packing ring from top to bottom.
Such as Fig. 2 and shown in Figure 4, when this anti-dust water-proof device 8 during normal the use, its shrouding I 2,3 docking of shrouding II are fixing, are positioned between the large base plate 6 of digger revolving centerbody 7 and revolving dial.Shrouding II 3 inserts groove 41 and both shapes are coincide, and has played good sealing function, and bottom is provided with rubber ring 5 in addition, can effectively block rainwater and dust and enter rotary system gear engagement place.
Such as Fig. 3 and shown in Figure 5, when needing repairing or change centre of gyration body 7, can unscrew the connecting bolt that passes through the U-shaped hole on this anti-dust water-proof device 8, then shrouding I 2, shrouding II 3 can all be launched to both sides by the connecting bolt of circular hole around another, slot milling, do not affect the maintenance of centre of gyration body 7 or change operation, visible easy accessibility is easy to safeguard.
