The invention discloses a tensioning device for a tracked vehicle, comprising an outer sleeve rod which is fixedly mounted on a chassis and is used for providing support; the inner sleeve rod is mounted in the outer sleeve rod in a sliding manner, and a mounting bracket is arranged at the end part of the inner sleeve rod; the tensioning wheel is rotationally arranged on the mounting bracket; the threaded seat is slidably mounted in the outer sleeve rod and used for pushing the inner sleeve rod to slide in the outer sleeve rod; the tensioning lead screw is installed in the outer sleeve rod in a penetrating mode, and a round hole matched with the tensioning lead screw is formed in the outer sleeve rod. The crawler belt tensioning device has the beneficial effects that the structural design that the inner sleeve rod is matched with the outer sleeve rod is adopted, the tensioning lead screw is rotated to be matched with the threaded base, then the inner sleeve rod is driven to move in the outer sleeve rod, the tensioning wheel is pushed to abut against the interior of the crawler belt to be supported, it is ensured that the crawler belt is safe and reliable in the transmission process, the derailing probability is reduced, operation is easy and convenient, and the practicability is high. The adjusting difficulty is low, and the durability is good.
本发明公开了一种履带车辆用张紧装置,包括:外套杆,所述外套杆固定安装在底架上,用于提供支撑;内套杆,滑动安装在外套杆内部,所述内套杆的端部设有安装支架;张紧轮,转动设置在安装支架上;螺纹座,滑动安装在外套杆内部,用于推动内套杆在外套杆内部滑动;张紧丝杆,贯穿安装在外套杆内,所述外套杆上开设有与张紧丝杆相配合的圆孔。有益效果在于:采用内套杆与外套杆相配合的结构设计,能够通过旋转张紧丝杆与螺纹座配合,进而带动内套杆在外套杆内部移动,推动张紧轮抵接至履带内部撑起,确保履带在传动过程中安全可靠,减少脱轨的几率,操作简单方便,调节难度低,耐用性好。
