Detailed description of the invention
The exemplary embodiments that embodies feature & benefits of the present invention will describe in detail in the following description.Be understood that the present invention can have various variations on different embodiment, it neither departs from interest field of the present invention, and explanation wherein and accompanying drawing be when the use that explain in itself, but not in order to limit the present invention.
The mine excavator of the embodiment of the present invention, has the ballast box of the embodiment of the present invention, and the ballast box of the embodiment of the present invention can be used in mine excavator.The mine excavator of the embodiment of the present invention is for example large-sized mining dredger etc.
Below specifically introduce the mine excavator of the embodiment of the present invention and the ballast box of the embodiment of the present invention.
As shown in Figure 1-Figure 3, the ballast box of the embodiment of the present invention, for large-scale mine forward shovel, comprising: casing 1, upper plugging plate 2, lower plugging plate 3, steel plate bar 4, inner hanger 5 and the bolt device 6 of rising.
As shown in Figure 5, the afterbody lower edge of revolving dial 7 has seam 8, and ballast box is positioned revolving dial 7 breech faces by seam 8, and ballast box is connected with revolving dial 7 by bolt device 6, and wherein, bolt device 6 for example comprises bolt, nut and pad.
As depicted in figs. 1 and 2, described casing 1, comprises horizontal bar 11, perpendicular muscle 12, upper cover plate 13 and lower cover 14, and casing 1 is formed by above weld parts; Horizontal bar 11 is cut apart casing 1 to go into several space cells (or claiming multiple lattices space, multiple grid) with perpendicular muscle 12, and as shown in Figure 1, the cross section of space cell is the quadrangle forms such as rectangle, positive direction, trapezoidal or parallelogram.
Wherein, upper cover plate 13 has slotted hole on the space cell (being grid) of each correspondence, and slotted hole can be level, vertical or incline direction; Lower cover 14 has circular hole on the space cell of each correspondence, and slotted hole is used for packing into weighted spherical ball, and circular hole is used for taking out weighted spherical ball.The radius of circular hole, is preferably greater than the transverse width of slotted hole, is less than longitudinal width of slotted hole, so that take out weighted spherical ball.Slotted hole also can be elliptical aperture.In addition, the slotted hole on upper cover plate 13 can be one or two, and the circular hole on lower cover 14 is one.
As shown in Figure 1, steel plate bar 4 is welded in upper cover plate 13 circular arc places, slotted hole both sides, inner side.
As shown in Figure 2 and Figure 4, the inner hanger 5 that rises is welded in casing 1 near in middle space cell, and inner rising on hanger 5 has and lift by crane circular hole 51, and weld with perpendicular muscle 12, upper cover plate 13 and lower cover 14 respectively on inner three limits of playing hanger 5.Can play hanger 5 by inside and lift by crane casing 1.Casing 1 can comprise that four are played hanger 5, but the present invention is not as limit.
As shown in Figure 4 and Figure 5, upper plugging plate 2 is Long Circle, in the middle of upper plugging plate 2, has circular hole, and inside is welded with nut 21, and the convenient upper plugging plate 2 of dismounting later, can be screwed into nut 21 by circular hole with a bolt and dismantle upper plugging plate 2.Upper plugging plate 2 is slightly less than the slotted hole on upper cover plate 13, after weighted spherical ball adds casing 1 interior, upper plugging plate 2 embedded in upper cover plate 13 slotted holes, and spot welding.
As shown in Figure 4 and Figure 5, lower plugging plate 3 is circular, and center has a small sircle hole, and for water or oil leakage in its place space cell are gone out, lower plugging plate 3 is slightly larger than the circular hole that lower cover 14 is opened, and lower plugging plate 3 is welded in the circular hole outside of lower cover 14.
After the normal work of excavator, after power shovel installation, ballast box top has been put high-voltage board etc., and only minority upper plugging plate 2 can appear, if it is few to find that weighted spherical ball increases, can continue to supplement by the slotted hole of both sides upper cover plate 14 above ballast box.If need extraction portion point weighted spherical ball, lower plugging plate 3 can be opened, extraction portion is divided weighted spherical ball, then lower plugging plate 3 is welded.
The ballast box of the embodiment of the present invention, after being generally in place, need not often dismantle, and adds, takes out weighted spherical ball conveniently.Reduce maintenance cost, improved economic benefit.
Although described the application with reference to exemplary embodiments, should be appreciated that term used is explanation and exemplary and nonrestrictive term.Because can specifically implementing in a variety of forms, the application do not depart from spirit or the essence of invention, so be to be understood that, above-described embodiment is not limited to any aforesaid details, and explain widely in the spirit and scope that should limit in the claim of enclosing, therefore fall into whole variations in claim or its equivalency range and remodeling and all should be the claim of enclosing and contain.
