The embodiment provides a guard plate assembly, a crawler belt guard plate and crawler belt type engineering machinery. The guard plate assembly comprises a guard plate, the guard plate is provided with a first side and a second side which are opposite to each other, the first side is provided with an arc-shaped groove used for assembling a thrust wheel, and the second side is provided with a curved surface protruding in the direction away from the groove bottom of the arc-shaped groove; the curved surface is used for contacting with a crawler plate. The crawler belt guard plate and the upwarped crawler plate are not prone to interference, and abrasion of the bottom of the crawler belt guard plate to the crawler plate is reduced; and the contact area of the crawler belt guard plate and a caterpillar track section is small, and abrasion of the caterpillar track section is reduced.

    本实施例提供了一种护板组件、履带护板和履带式工程机械,护板组件包括护板,护板具有相对的第一侧和第二侧,第一侧设有用于装配支重轮的弧形槽,第二侧设为向远离弧形槽的槽底的方向凸出的弯曲面;弯曲面用于与履带板接触。履带护板与上翘的履带板不易产生干涉,减少履带护板底部对履带板的磨损;且履带护板和链轨节的接触面积小,减少链轨节的磨损。
