Abstract
The utility model provides a guide wheel of a chain disengagement prevention excavator and relates to an excavator accessory device, in particular to a guide wheel of an excavator. The guide wheel is provided with a body (1), a mounting hole is formed in the center of the body, and a boss (3) is arranged at the outer edge of the body and corresponds to a groove of a caterpillar track junction. The guide wheel is characterized in that anti-disengagement teeth (2) are annularly arranged on the boss, and the number of the anti-disengagement teeth is the same as that of driving wheels of the excavator. The guide wheel has the advantages of preventing a caterpillar track from disengaging when the excavator is steered and reducing the failure rate.
Description
Technical field
The utility model relates to a kind of excavator fixture, particularly belongs to a kind of guide wheel of excavator.
Background technology
When excavator assists bank machinery to unload bulk goods belowdecks; usually have wet sticky goods and be attached to chain rail joint groove; goods in groove is constantly compacted in the process of moving; cause chain rail joint groove cannot effectively engage with guide wheel boss; when excavator turns to, chain rail very easily comes off, and causes fault to occur.
Summary of the invention
The purpose of this utility model is to provide a kind of novel anti-fall off chain guide wheel for excavator, to reach the object that makes guide wheel and chain rail joint effectively engage, reduce fault rate.
Anti-fall off chain guide wheel for excavator provided by the utility model, has body, and body center is installing hole, body outer rim has boss, corresponding with the groove of chain rail knot, it is characterized in that, on above-mentioned boss, circular row is furnished with anticreep tooth, and the number of teeth of anticreep tooth is consistent with the number of teeth of excavator driving wheel.
Anti-fall off chain guide wheel for excavator provided by the utility model, on original guide wheel basis, weld anticreep tooth, anticreep tooth is easily wedged in the goods that chain rail joint groove is compacted, thereby chain rail joint can effectively be engaged with guide wheel, have and prevent that excavator from chain rail occurring in the time turning to come off, reduce the good effect of fault rate.
Accompanying drawing explanation
Accompanying drawing part discloses specific embodiment of the utility model, wherein,
Fig. 1, the utility model partial cutaway schematic;
Fig. 2, the utility model structural representation.
The specific embodiment
As shown in drawings, anti-fall off chain guide wheel for excavator provided by the utility model, the central authorities of guide wheel body 1 are installing hole, coordinate with axle.On the rail level that the boss 3 of guide wheel body outer rim forms, be evenly provided with 7 anticreep teeth 2, be circular row and arrange.Obviously, the number of teeth of above-mentioned anticreep tooth is consistent with the driving wheel number of teeth of same specification excavator.
As shown in Figure 1, the rectangular shape of anticreep tooth facade, can reduce lifting surface area, is beneficial in the anticreep tooth goods that effectively wedging is compacted, thereby chain rail joint can effectively be engaged with guide wheel, prevents that excavator from chain rail occurring in the time turning to and come off.
The separation preventing guide wheel that the utility model provides, anticreep tooth can adopt waste and old track (shoe) to be welded on former guide wheel and be made, and makes full use of the good abrasion resistance that excavator track (shoe) has itself, economize on resources, reduction expense, easy for installation, and application life is longer.
Claims (2)
1. an anti-fall off chain guide wheel for excavator, there is body (1), body center is installing hole, body outer rim has boss (3), corresponding with the groove of chain rail knot, it is characterized in that, on above-mentioned boss, circular row is furnished with anticreep tooth (2), and the number of teeth of anticreep tooth is consistent with the number of teeth of excavator driving wheel.
2. anti-fall off chain guide wheel for excavator according to claim 1, is further characterized in that, described anticreep tooth (2) facade is rectangular.
