According to the crawler-type tunnel excavation trolley, a first Y-shaped plate and a second Y-shaped plate are each of a Y-shaped structural body composed of the end portion of a V-shaped opening formed by two branch structures and the tail portion extending from the V-shaped combination portion of the two branch structures, and the tail portion of the first Y-shaped plate drives a wheel through a first connecting piece; the tail portion of the second Y-shaped plate is provided with an advancing wheel through a second connecting piece, the lower end of the first Y-shaped plate and the lower end of the second Y-shaped plate are each provided with a ground grabbing wheel, the upper end of the first Y-shaped plate and the upper end of the second Y-shaped plate are connected through a hydraulic spring buffer, and pressure of the trolley body acts on the two moving assemblies through a supporting plate. The track supporting wheels, the driving wheels and the advancing wheels can freely move front and back under the action of being matched with the track, the road holding force of the track is improved under the matching action of the first Y-shaped plate and the second Y-shaped plate, the tensioning degree of the track can be adjusted, and meanwhile a certain damping effect is achieved.

    本发明提供的一种履带式隧道开挖台车,第一Y型板和第二Y型板均由两分支结构构成V形开口的端部和在该两分支结构的V形结合部延伸的尾部构成的Y型结构体,第一Y型板的尾部通过第一连接件驱动轮,第二Y型板的尾部通过第二连接件前进轮,第一Y型板和第二Y型板位于下方的端部均安装有抓地轮,第一Y型板和第二Y型板位于上方的端部间通过液压弹簧缓冲器相连接,台车本体的压力通过支撑板作用在两个移动组件上,托带轮、驱动轮以及前进轮再配合履带作用下,能够实现前后自由移动,在第一Y型板和第二Y型板的配合作用,不仅提高了履带的抓地力,而且能够对履带的张紧度调节实现调整,同时起到一定的减震作用。
