Abstract
The utility model discloses a supporting wheel of a crawler walking device. The supporting wheel comprises a supporting wheel body (1); a bump (2) which is corresponding to a walking crawler is arranged in the middle of the supporting wheel body (1); the profiles (3) on the two sides of the bump (2) are shaped like arc lines; and the supporting wheel is applicable to mining mechanical crawler walking devices on uneven ground.
Description
Technical field
The utility model relates to a kind of mining machinery track unit, particularly a kind of track unit caterpillar wheel.
Background technology
The track unit of this mining machinery is provided with drive wheel and flower wheel in the front and back of walker, in the walker bottom a plurality of caterpillar wheels are set, by these wheels roll a plurality of caterpillar blocks link to each other and the osed top crawler belt on constitute, because having enlarged ground-surface relatively ground contact area has reduced grounding pressure, makes in ground-surface performances of passing through such as soft atures of coal to be improved.
Above-mentioned track unit, because ground-surface concavo-convex, caterpillar block tilts, common caterpillar wheel outer rim contacts with crawler belt is local, produces very big stress, causes very quick-wearing of caterpillar wheel outer rim, therefore, in the exploitation of track unit, reducing such wearing and tearing is important topics.
With regard to the situation of above-mentioned discussion, therefore, crawler belt and caterpillar wheel can be damaged, though in that oneself knows stress and the consequent wearing and tearing that have a variety of methods to reduce crawler belt and caterpillar wheel aspect this.
ZL 200620050612.2 has described a kind of have inward flange, outward flange, can satisfy the caterpillar wheel of the stability requirement of steel crawler belt and rubber belt track simultaneously, yet it is too high not solve the crawler belt local stress, and consequent caterpillar wheel wear problem.
ZL 93227572.9 discloses a kind of compound type wheel body caterpillar wheel, and replaceable wheel rim is compressed on the wheel hub, behind wheel wear, can only change wheel rim, and wheel hub continues to use.This helps reducing manufacturing cost, and certain economic implications is arranged, but does not have the basic caterpillar wheel wear problem that solves.
The utility model content
The utility model is put in view of the above problems and is made, and its purpose is that providing a kind of can solve because of the ground-surface concavo-convex caterpillar wheel wear problem that produces that waits by reducing local contact stress.
The utility model has been taked following technical scheme in order to reach this purpose:
A kind of track unit caterpillar wheel of the utility model is characterized in that, projection (2) is arranged in the middle of the described caterpillar wheel body (1), and the profile (3) of projection (2) both sides is arc line type.
Adopt a kind of track unit caterpillar wheel of technique scheme,, play position-limiting action, prevent the traveling crawler derailing owing on the caterpillar wheel body, be provided with and the cooresponding intermediate projections of traveling crawler (2).When traveling crawler one side ran into concavo-convex obstacle, a side can be lifted, and caterpillar wheel arc line type profile (3) continues and the crawler belt effect, guarantees certain area of contact, was not easy to produce very big local contact stress in the caterpillar wheel outer rim, reduced the wearing and tearing of caterpillar wheel.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is a kind of track unit scheme drawing.
Fig. 3 is the utility model embodiment running condition scheme drawing.
Fig. 4 is common caterpillar wheel running condition scheme drawing.
Among the figure, 1 caterpillar wheel body, 2 projectioies, 3 profiles, 11 drive wheels, 12 walkers, 13 caterpillar wheels, 14 crawler belts, 15 flower wheels.
The specific embodiment
Below, with reference to description of drawings embodiment of the present utility model.
Referring to Fig. 2, a kind of track unit of the present utility model is adopted in expression, be provided with flower wheel (15) and drive wheel (11) in the front and back of walker (12), the bottom is provided with a plurality of caterpillar wheels of the present utility model (13), and rolling by these wheels upward constitutes at the continuous also osed top crawler belt (14) of a plurality of caterpillar blocks.
Referring to Fig. 3, when crawler belt one side ran into convex-concave ground, caterpillar wheel body arc line type profile (3) contacted with crawler belt, and contact stress is little, was not easy wearing and tearing.
Referring to Fig. 4, when crawler belt one side ran into convex-concave ground, common caterpillar wheel body outer rim contacted with crawler belt, produced very big local contact stress, serious wear.
If caterpillar block adopts the predeformation technology, contact portion also is arc line type, and when crawler belt one side ran into convex-concave ground, caterpillar wheel body arc line type profile (3) contacted better effects if with the arc line type crawler belt.
Claims (1)
1. a track unit caterpillar wheel comprises caterpillar wheel body (1), it is characterized in that: be provided with projection (2) in the middle of the described caterpillar wheel body (1), the profile (3) of projection (2) both sides is arc line type.
