The invention provides a crawler belt tensioning device and crawler belt type engineering machinery, and relates to the technical field of engineering machinery. The crawler belt tensioning device comprises a cylinder body, a pull rod, a support, an ejector rod, a spring and an elastic buffering piece. One end of the cylinder body is connected to the pull rod; the support is slidably connected tothe pull rod and used for being connected with a guide wheel of a tensioning crawler; the end, away from the pull rod, of the cylinder body is connected to the ejector rod; and the ejector rod can extend out relative to the cylinder body to abut against a chassis limiting plate of the crawler-type engineering machine. The cylinder body is sleeved with the spring, one end of the spring is connectedto the cylinder body, the other end of the spring is connected to the support, the buffering piece is connected to the spring, and at least one part of the buffering piece is located between two adjacent coils of the spring. The crawler-type engineering machinery comprises the crawler belt tensioning device. The crawler belt tensioning device can reduce damage to the spring and reduce the influence on the reliability of the device and crawler belt type engineering machinery.

    本发明提供了一种履带张紧装置和履带式工程机械,涉及工程机械技术领域。履带张紧装置包括缸体、拉杆、支座、顶杆、弹簧和具有弹性的缓冲件,缸体的一端连接于拉杆,支座滑动连接于拉杆,支座用于连接张紧履带的引导轮,缸体远离拉杆的一端连接于顶杆,顶杆能相对缸体伸出以抵持于履带式工程机械的底盘限位板。弹簧套设于缸体外,弹簧的一端连接于缸体,另一端连接于支座,缓冲件连接于弹簧且缓冲件的至少一部分位于弹簧相邻的两个螺圈之间。履带式工程机械包括上述履带张紧装置。履带张紧装置能够减少对弹簧的损伤,降低对装置以及履带式工程机械的可靠性的影响。
