In order to solve the technical problems that a track tensioning device in the prior art is large in size and inconvenient to use, the invention discloses a track tensioning device for an amphibious tracked ship. The track tensioning device comprises a driven wheel, a Z-shaped crank, a screw rod and an adjusting seat, one end of the Z-shaped crank penetrates out of a sleeve fixed in a ship body to form a connecting part; a crank arm perpendicular to the connecting part is installed on the connecting part, a rotatable shaft rod is installed in a through hole formed in the crank arm, and a nut is fixedly arranged in the center of the shaft rod; the adjusting seat is fixed in the ship body, one end of the screw is located in the groove of the adjusting seat, and the other end is screwed into the nut. During tensioning adjustment, the position of the driven wheel in the crawler belt is adjusted by screwing the screw rod and depending on the eccentric distance of the Z-shaped crank, the purpose of tensioning the crawler belt is achieved, adjustment is convenient and easy, and the adjusting part of the whole tensioning device is arranged outside the crawler belt and does not occupy a large space in the crawler belt.
本发明为了解决现有技术中的履带张紧装置体积大、使用不便的技术问题,公开了一种水陆两栖履带船用履带张紧装置,包括从动轮、Z型曲柄、螺杆和调节座,Z型曲柄的一端从固定于船体中的套管内穿出形成连接部;连接部上安装有与之垂直的曲柄臂,曲柄臂中设置的通孔内安装有可转动的轴杆,轴杆中心处固设有螺母;调节座固定于船体中,螺杆一端位于调节座的凹槽内,另一端拧入螺母内。张紧调节时只需旋拧螺杆依靠Z型曲柄的偏心距去调节从动轮在履带中的位置,达到履带紧张的目的,调节方便、简单,整个张紧装置的调节部分设置于履带的外部,不会在履带内占用较大的空间。
