The invention relates to a maintainable tensioning device for an engineering machinery crawler belt, relates to the technical field of engineering machinery crawler belts, solves a problem that the tensioning device is easy to damage; the device comprises a support, a connecting rod, an end cover, a spring, a spring box body, an oil cylinder and a piston, the spring is arranged in the spring box body, the oil cylinder is arranged in the spring, and an oil injector is arranged at one end of the oil cylinder. A piston is arranged in the oil cylinder, one end of the connecting rod is connected with the piston, the other end of the connecting rod is connected with the support through a bolt, the end cover is arranged at an outlet, extending out of the spring box body, of the connecting rod, abush is arranged on the cylindrical face of an inner hole of the end cover, a dustproof ring is arranged on the outer side of the bush, and a cover plate is arranged on the outer side of the end cover. When a guide wheel walks up and down, axial load is transmitted between the connecting rod and the piston, and problems of eccentric wear and oil leakage of the sealing ring caused by lateral load are solved; the contact ends of the pull rod and the piston are matched spherical surfaces with the same size, and the influence of lateral loads is eliminated through spherical surface matching.

    一种用于工程机械履带的可维护张紧装置,涉及工程机械履带技术领域,解决了张紧装置易损坏的问题,包括支架、连接杆、端盖、弹簧、弹簧箱体、油缸和活塞,所述的弹簧设置在弹簧箱体中,所述的油缸设置在弹簧内部,油缸的一端设置有注油器,所述的活塞设置在油缸内,所述的连接杆的一端与活塞相连接,连接杆的另一端通过螺栓与支架相连接,所述的端盖设置在连接杆伸出弹簧箱体的出口处,端盖的内孔圆柱面上设置有衬套,衬套的外侧设置有防尘圈,端盖的外侧设置有盖板;当引导轮行走起伏时,连接杆与活塞之间传递轴向载荷,解决了侧向载荷引起密封圈偏磨、漏油的问题;拉杆、活塞接触端为尺寸相同的配合球面,球面配合消除了侧向载荷的影响。
