In the accompanying drawings, for the purpose of clear, some embodiments of the present invention are simplified demonstration.In these accompanying drawings, identical parts are represented with identical Reference numeral.
The specific embodiment
In Fig. 1, quartering hammer 1 is arranged on the free end such as the cantilever 3 of the Work machine 2 of excavator.Quartering hammer 1 can be arranged in any movably Work machine 2, perhaps for example is arranged on the cantilever that is installed on the firm banking.Quartering hammer 1 comprises percussion mechanism 4, utilizes this percussion mechanism can produce shock pulse.With by percussion mechanism 4 with impact offer be connected to quartering hammer 1 instrument 6 simultaneously, quartering hammer 1 applies pressure to by cantilever 3 and treats broken material 5, this instrument with described transmission of impacts to the material 5 for the treatment of fragmentation.Percussion mechanism 4 can be a hydraulic pressure, and it can be connected to the hydraulic system of Work machine 2 thus.On the other hand, percussion mechanism 4 can be another type, and is for example electronic.In addition, shock pulse can be by the impact components that moves in complex way in percussion mechanism 4, or produces in any other mode.
Quartering hammer 1 comprises protecting sheathing 7, and percussion mechanism 4 completely or partially is arranged on this protecting sheathing 7 inside.The purpose of protecting sheathing 7 is that protection percussion mechanism 4 does not in use produce indenture.Protecting sheathing 7 can be the hermetically-sealed construction around percussion mechanism 4, and it can prevent that moisture, dust and other impurity from entering percussion mechanism 4 thus.Instrument 6 inserts by the bottom of protecting sheathing 7.Between the bottom of instrument 6 and protecting sheathing 7, can have sealing device.For making protecting sheathing 7 tolerances be applied to its stress, protecting sheathing 7 is made by steel or other metal usually, is made by sheet material usually.Fig. 1 shows that also protecting sheathing 7 can be the part of the fastener of quartering hammer 1.Fastener 17 is arranged in the top of protecting sheathing 7, perhaps in the top or as among Fig. 1 on its side.
Fig. 2 has shown feasible protecting sheathing 7, and this protecting sheathing 7 is included in lower end 8a, promptly at the first housing parts 7a of the bottom at place, the end of instrument 6 sides and at the second housing parts 7b on the top at relative 8b place, upper end.The second housing parts 7b can be formed by two halfbody 9a, 9b, and described two halfbodies bend to roughly U-shaped and lean on each other and are provided with, and for example utilizes longitudinal weld longitudinal seam 10 and secured to one another.Perhaps, the second housing parts 7b can be the casting object of one, and perhaps it can be welded by surpassing two parts.The top of the second housing parts 7b can further comprise the fastening surface 11 such as flange or other securing member, utilizes this fastening surface 11 quartering hammer can be fastened to cantilever 3.The first housing parts 7a and the second housing parts 7b are can be for example secured to one another by welding, perhaps alternatively, have certain other fastener between the first housing parts 7a and the second housing parts 7b.If the first housing parts 7a damages, then also it can be pulled down.
To shown in Figure 4, the structure of the first housing parts 7a is different with the structure of the second housing parts 7b as Fig. 2.The cross section of the first housing parts 7a can be included in the fillet bight 13a a plurality of side plate 12as secured to one another to the 13d place to 12d.Typically, the cross section of protecting sheathing 7 is square or rectangle substantially, and comprises four side plates 12 and four corner portions 13.Yet this cross section can also be another type, in this case, may have several side plates.Fillet bight 13 is provided with from the lateral flange 15 that is positioned at housing parts 7a lower end and extends to the extension rod 14a of housing parts 7a upper end to 14d.Bar 14 also can be a circular pin.The edge of side plate 12 can be fastened to bar 14 at corner portion 13 places by vertical soldered.
Fig. 5 has shown a kind of protecting sheathing 7, at 13 places, the corner of protecting sheathing 7, has the bar 14 that extends to the flange 16 that is positioned at 8b place, top from the flange 15 that is positioned at protecting sheathing bottom 8a.Therefore, protecting sheathing 7 only comprises a housing parts, and these are different with the protecting sheathing shown in Fig. 2.Protecting sheathing 7 still is taper, this means that it narrows down towards lower end 8a.Flange 16 can be provided with fastening flange 17 etc., and described fastening flange 17 can comprise secured opening 18 etc., is used for it is fixed to cantilever.
From the cross section of the protecting sheathing shown in Fig. 67, can see, side plate 12a to vertical limit of 12d can be tilt or be shaped with a certain alternate manner, thereby form corner portion 13.Thus, between bar 14 with rounded outer surface and side plate 12, form the bevel angle 19 of expection, weld seam 20 is welded to this bevel angle 19.For the purpose of clear, two weld seams 20 have only been shown among the figure.Bar 14 can be a tubulose, in this case, for example hydraulic tube 21, lubricant passageway or electric wire can be placed on bar 14 inside.Fig. 6 shows that also the thickness of side plate 12 can select as required.In this case, side plate 12c is thicker than other side plate.The cross section of protecting sheathing 7 also can comprise one or more stiffeners 22.Stiffener 22 can lean on side plate 12 and be arranged between the bar 14.Stiffener 22 can be the integral part of removable wear-out part or protecting sheathing 7.
Fig. 7 has shown the rectangular cross section of protecting sheathing 7, wherein side plate 12a to the turning 13a between the 12d to the external surface of 13d, be provided with bar 14a to 14d, it is square or the rectangle outline that the cross section of bar has the right angle.
Fig. 8 has shown the cross section of protecting sheathing 7, wherein side plate 12a to the 13a of corner portion between the 12d to the external surface of 13d, be provided with have the polygon cross section bar 14a to 14d.The cross section of bar 14 can have the exterior contour that for example comprises 5 to 8 angles.
Except when when seeing from below, the first housing parts 7a of bottom extends to such an extent that obviously exceed the middle part of protecting sheathing, protecting sheathing 7 shown in Fig. 9 and the scheme basically identical shown in Fig. 2.The cross section of the first housing parts 7a thereby can be similar with the cross section of the housing parts shown in Fig. 4 to Fig. 3.Alternatively, this cross section can be consistent to Fig. 8 with Fig. 6.The first housing parts 7a can also be taper.And second housing parts 7b can be taper.
Two housing parts 7a, 7b of protecting sheathing also can have cross section, and in this cross-section, bar 14 is arranged on corner portion 13 places.Bar 14 also can only extend to the specific part of housing parts 7a, 7b, for example extends to the part of bearing maximum stress usually of lower end 8a.In some cases, bar thereby can obviously under the middle part of protecting sheathing, extend.Can also not that each corner portion all comprises bar, but only have some corner portion to be provided with bar.
Should be noted that extension rod also can be arranged on the corner portion place of the protecting sheathing with different structural types.Therefore, the cross section of protecting sheathing can comprise two roughly halfbodies of U-shaped, and the longitudinal seam between the wherein said halfbody is not formed on corner portion place and is formed on the side of protecting sheathing.In this case, extension rod also can be arranged on the structure that corner portion sentences the described corner of support portion.Also can have elongated, crooked connector at the corner of protecting sheathing portion place.Equally in this case, corner portion also can be provided with the extension rod of stiffened edge corner structure.
In some cases, such use that the feature described in this application can be as described in the present application, and no matter further feature.On the other hand, if necessary, then the feature described in the application can combine to form different combinations.
Accompanying drawing and associated description only are intended to illustrate notion of the present invention.Specifically, the present invention can change within the scope of the claims.
