The invention relates to a guide device of a crawler excavator, and the crawler excavator. The guide device comprises: a guide wheel body provided with an axial through hole; a guide circular ring, wherein the inner ring surface of the guide circular ring is connected with the wheel surface of the guide wheel body through a key or a pin, and the guide wheel body drives the guide circular ring to do circular motion; and a first tread circular ring and a second tread circular ring which are respectively arranged on two sides of the guide circular ring, the first tread circular ring and the second tread circular ring are used for axially limiting the guide circular ring and the guide wheel body, the first tread circular ring is detachably and fixedly connected to the guide wheel body and/or the guide circular ring, the second tread circular ring is detachably and fixedly connected to the guide wheel body and/or the guide circular ring, and the outer diameter of the guide circular ring islarger than the outer diameter of the first tread circular ring and the outer diameter of the second tread circular ring. The guide wheel body, the guide circular ring and the tread circular rings arerespectively arranged, and the corresponding guide circular ring can be arranged according to requirements, so that the universality and the interchangeability of the guide device are improved, and the replacement cost is reduced.

    本发明涉及一种履带式挖掘机的引导装置及履带式挖掘机,引导装置,包括设置有轴向通孔的引导轮体;导向圆环,导向圆环的内环面与引导轮体的轮面通过键或销连接,引导轮体带动导向圆环做圆周运动;分别设置于导向圆环两侧的第一踏面圆环和第二踏面圆环,第一踏面圆环和第二踏面圆环用于对导向圆环和引导轮体进行轴向限位,第一踏面圆环可拆卸固定连接于引导轮体和/或导向圆环上,第二踏面圆环可拆卸固定连接于引导轮体和/或导向圆环上,且导向圆环的外径大于第一踏面圆环的外径和第二踏面圆环的外径。该引导装置通过分别设置引导轮体、导向圆环和踏面圆环,可根据需求设置相对应的导向圆环,提高了引导装置的通用性和互换性,降低了更换成本。
