Abstract
A nested structure for open cast mine large excavator, comprising: caterpillar wheel, and described caterpillar wheel supporting section step outside socket is fixed with outer wheel, and the Internal periphery of described step outer circumferential profile and described outer wheel is corresponding.Adopt split-type design, the overcoat of caterpillar wheel can arbitrarily be changed, and it is more reasonable to design.During replacing, only need change overcoat, reduce use cost.After structure is simple, the caterpillar wheel overcoat after split design adopts forging during fabrication, and the supporting construction of inside can adopt casting thus reduce productive costs.Solve caterpillar wheel outer ring in use procedure and after easily wearing and tearing, change the too high problem of use cost.
Description
Technical field
The utility model relates to a kind of nested structure of open cast mine large excavator.
Background technology
At present, the caterpillar wheel of crawler rack is generally formed by overall forging.Mainly in order to meet the requirement of caterpillar wheel intensity and resistance to abrasion, and need through Technology for Heating Processing several times.In addition on the one hand, caterpillar wheel is consumable accessory, often needs to change.No matter be manufacture, or use all causes a large amount of wastes.Need a kind of nested structure of open cast mine large excavator badly, solve caterpillar wheel outer ring in use procedure and easily wear and tear and changing the too high problem of use cost.
Summary of the invention
The purpose of this utility model is the nested structure providing a kind of open cast mine large excavator, solves caterpillar wheel outer ring in use procedure and easily weares and teares and changing the too high problem of use cost.
The utility model adopts following technical scheme:
A kind of nested structure of open cast mine large excavator, comprise: caterpillar wheel (2), the socket of described caterpillar wheel (2) supporting section step (21) outside is fixed with outer wheel (22), and the Internal periphery of described step (21) outer circumferential profile and described outer wheel (22) is corresponding.
The outline of described outer wheel (22) is halo.
Advantage of the present utility model is as follows:
1. adopt split-type design, the outer wheel of caterpillar wheel can arbitrarily be changed, and it is more reasonable to design.
2. only need outer wheel when changing, reduce use cost and maintenance cost.
Accompanying drawing illustrates:
Fig. 1 is the utility model supporting wheel structure schematic diagram;
Fig. 2 is that the utility model caterpillar wheel and outer wheel assemble exploded perspective view;
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.
Following examples are only be clearly this example of utility model, and the restriction not to embodiment of the present utility model.For those of ordinary skill in the field; can also make other multi-form change or variations on the basis of the following description, and these belong to the utility model spirit apparent change of drawing or variation is still among protection domain of the present utility model.
A nested structure for open cast mine large excavator, comprising: caterpillar wheel 2, and described caterpillar wheel 2 supporting section step 21 outside socket is fixed with outer wheel 22, and the Internal periphery of described step 21 outer circumferential profile and described outer wheel 22 is corresponding.
The outline of described outer wheel 22 is halo.
As shown in Figure 1-2, in actual use, described caterpillar wheel 2, originally for solid forging or foundry goods are for meeting mechanical characteristics, so must with expensive material, and require to adopt strict Technology for Heating Processing, makes surface have good resistance to abrasion.Adopt described outer wheel 22 bushing in load-bearing section, then after caterpillar wheel wearing and tearing, outer ring can be machined away, then cover connects new outer wheel 22.
Structure is simple, and the outer wheel 22 of the caterpillar wheel after split design adopts casting forging structure during fabrication, and the heat treatment method matched, and meet the requirements of intensity and resistance to abrasion, and the supporting construction of inside can adopt casting to process.
Claims (2)
1. the nested structure of an open cast mine large excavator, comprise: caterpillar wheel (2), it is characterized in that: the socket of described caterpillar wheel (2) supporting section step (21) outside is fixed with outer wheel (22), and the Internal periphery of described step (21) outer circumferential profile and described outer wheel (22) is corresponding.
2. the nested structure of a kind of open cast mine large excavator according to claim 1, is characterized in that: the outline of described outer wheel (22) is halo.
