The invention discloses an automobile crane jib cylinder stretching protection device which comprises a base, a rotating frame is fixedly mounted at the top end of the base, a jib cylinder is mounted in the rotating frame, a lubricating mechanism is arranged outside the jib cylinder, the lubricating mechanism comprises a mounting frame, bolts, a sealing assembly and a lubricating assembly, and a plurality of counter bores are formed in the outer wall of the mounting frame at equal intervals. A plurality of mounting holes are formed in the outer wall of the suspension arm cylinder at equal intervals, the bolts are in threaded penetrating connection with inner cavities of the mounting holes, the lubricating assembly is arranged outside the mounting frame, and the sealing assemblies are arranged on the two sides of the mounting frame correspondingly. By means of the arrangement mode that the mounting frame, the bolts, the sealing assembly and the lubricating assembly are matched, when the telescopic arm stretches out, the outer wall of the stretching-out telescopic arm can be evenly lubricated, the lubricating effect is good, the sealing gasket can be evenly scraped and lubricated, meanwhile, lubricating oil is not prone to overflowing, the usable time is long, and frequent adding is not needed.

    本发明公开了一种汽车起重机吊臂筒伸缩的保护装置,包括底座,其顶端固定安装有转动架,转动架的内部安装有吊臂筒,吊臂筒的外部设置有润滑机构,润滑机构包括有安装框、螺栓、密封组件和润滑组件,安装框的外壁等距开设有多个沉孔,螺栓与沉孔的内腔滑动穿插连接,吊臂筒的外壁等距开设有多个安装孔,螺栓与安装孔的内腔螺纹穿插连接,润滑组件设置于安装框的外部,多个密封组件分别设置于安装框的两侧。本发明利用安装框、螺栓、密封组件和润滑组件相配合的设置方式,在伸缩臂伸出时,会对伸出的伸缩臂外壁均匀润滑,润滑效果好,且密封垫可以均匀刮涂润滑的同时,使得润滑油不易溢出,且可用时间较长,不用频繁添加。
