The utility model solves the technical scheme that its technical matters adopted:
A kind of later-model link-supporting plate structure; Comprise link-supporting plate; Wherein, Also comprise plurality of fixed seat and some pressing plates; Said plurality of fixed seat is fixed on the walker surface, and the subregion on the surface of each said permanent seat is recessed into plane plano-concave portion downwards, the corner of said link-supporting plate respectively with the mutual embedding of plano-concave portion of said plurality of fixed seat after last plane and the last plane of said plurality of fixed seat of said link-supporting plate be on the same horizontal surface; And in being different from of each said permanent seat said plano-concave portion the surface be provided with first screw; Be respectively equipped with at said some pressing plates two ends and the corresponding second coaxial screw of said first screw, pass respectively with some bolts that said pressing plate and said permanent seat, said link-supporting plate fit behind said first screw and said second screw coaxial with it, the line of centers that said link-supporting plate is fixed afterwards with walker is an axis of symmetry.
Above-mentioned novel link-supporting plate structure, wherein, said plurality of fixed seat is four permanent seats, the said plano-concave portion on each said permanent seat respectively with four mutual embeddings in angle of said link-supporting plate.
Above-mentioned novel link-supporting plate structure, wherein, said some pressing plates are two block length strip pressing plates, every said pressing plate two ends have said second screw that cooperatively interacts with said first screw.
Above-mentioned novel link-supporting plate structure, wherein, the arrangement mode of said two block pressur plates is consistent with the direction of travel of said walker.
Above-mentioned novel link-supporting plate structure, wherein, said some pressing plates and corner, said permanent seat outer are provided with chamfering.
The utility model compared with prior art, advantage shows: can change at any time after 1. link-supporting plate damages, save maintenance cost; 2. after the former link-supporting plate wearing and tearing, form groove, can not crawler belt be held up, cause the suffered load of track carrying wheel to increase sharply, and this novel link-supporting plate can continue to play the effect that holds up crawler belt after changing, reduce the frequency that has an accident.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further, but not as the qualification of the utility model.
Please referring to Fig. 2 and shown in Figure 3, the later-model link-supporting plate structure of the utility model comprises link-supporting plate 7, wherein, also comprises plurality of fixed seat 8 and some pressing plates 10, and plurality of fixed seat 8 is fixed on walker 6 surfaces.
Shown in Fig. 4 a and Fig. 4 b, the subregion on the surface of each permanent seat 8 is recessed into plane plano-concave portion 81 downwards, and is provided with first screw 82 in the surface that is different from plano-concave portion 81 of each permanent seat 8.
Once more referring to Fig. 2 and Fig. 3; The corner of link-supporting plate 7 respectively with the plano-concave portion 81 mutual embeddings of plurality of fixed seat 8; The last plane of link-supporting plate 7 and the last plane of plurality of fixed seat 8 are on the same horizontal surface; Be respectively equipped with at some pressing plates 10 two ends and the second coaxial screw 101 of corresponding first screw 82, pass first screw 82 respectively and second screw 101 coaxial with it fits pressing plate 10 and permanent seat 8, link-supporting plate 7 with some bolts 9, link-supporting plate 7 just can play the effect of support crawler belt like this.Line of centers with walker 6 after link-supporting plate 7 is fixed is an axis of symmetry; Permanent seat 8 position of weld need guarantee that track link rail do not interfere with permanent seat 8; And short transverse need guarantee that this novel link-supporting plate 7 is consistent with former link-supporting plate, when design, will consider the position and the position of weld of permanent seat 8 on walker 6 of shape, first screw 82 and second screw 101 of permanent seat 8.When being welded permanent seat 8; Need to locate by the track link rail model; The line of centers of model needs overlapping with walker 6 line of centerss; Each hole of model is coaxial with permanent seat 8 each hole, and is collinear to guarantee link-supporting plate 7 line of centerss and other each wheel (not marking in the drawings) line of centers, and the equal erection bolt 9 smoothly of 4 mounting holes of permanent seat.
Further, plurality of fixed seat 8 is four permanent seats, the plano-concave portion 81 on each permanent seat 8 respectively with four mutual embeddings in angle of link-supporting plate 7, guarantee that link-supporting plate 7 can be fastened on the walker 6.
Further, shown in Fig. 5 a and Fig. 5 b, some pressing plates 10 are two block length strip pressing plates, and every block pressur plate 10 two ends have second screw 101 that one and first screw 82 cooperatively interacts, and the arrangement mode of two block pressur plates 10 is consistent with the direction of travel of walker 6.
Further, some pressing plates 10 are provided with chamfering (not marking in the drawings) with corner, permanent seat 8 outer, play to prevent that running gear from hanging between crawler belt (not marking in the drawings) and the link-supporting plate 7 when walking.
In sum, the utility model is made very little change on original design basis, because the utility model belongs to mounted version, is superior to the version of welded type, can be convenient for changing link-supporting plate, saves maintenance cost; Owing to can change at any time after the link-supporting plate wearing and tearing form groove,, reduce the frequency that has an accident so can avoid causing the suffered load of track carrying wheel to increase.
The above is merely the utility model preferred embodiment; Be not thus the restriction the utility model claim; So the equivalent structure that all utilization the utility model specification sheetss and diagramatic content have been done changes, and all is included in the protection domain of the utility model.
