一种带有机械自锁装置的环形液压缸
摘要：
本发明提供了一种带有机械自锁装置的环形液压缸。包括:缸座、环形缸体、环形活塞。环形缸体通过螺钉固定安装在缸座上，环形活塞与环形缸体配合形成封闭的液压腔，环形活塞与环形缸体上都安装有密封圈，环形缸体上开有进油孔，缸座上开有两个对称分布的自锁槽，自锁槽中安装有自锁销与自锁弹簧，自锁槽、自锁弹簧与自锁销构成机械自锁装置。本发明结构简单，安装方便，在液压缸将承重轴顶起时能够实现机械自锁。
摘要（英）：

The invention provides an annular hydraulic cylinder provided with mechanical self-locking devices. The annular hydraulic cylinder comprises a cylinder base, an annular cylinder body and an annular piston, wherein the annular cylinder body is fixedly mounted on the cylinder base through screws, the annular piston is matched with the annular cylinder body to form a closed hydraulic cavity, sealing rings are mounted on the annular piston and the annular cylinder body, an oil inlet hole is formed in the annular cylinder body, two symmetrically distributed self-locking grooves are formed in the cylinder base, self-locking pins and self-locking springs are mounted in the self-locking grooves, and the self-locking grooves, the self-locking springs and the self-locking pins form mechanical self-locking devices. The annular hydraulic cylinder is simple in structure and convenient to mount and can realize mechanical self-locking when the hydraulic cylinder jacks a bearing shaft.
