The invention relates to a crane jib lubricating grease filling mechanism which comprises an outer jib and an inner jib, the inner jib is movably arranged in the outer jib, sliding blocks are fixedly installed on the outer walls of the two sides of the inner jib, grease storage cavities are formed in the sliding blocks, the two sliding blocks are slidably connected with the inner wall of the outer jib, and the grease storage cavities are communicated with the inner wall of the outer jib. A material injection mechanism is movably arranged at the top of the sliding block, and a feeding mechanism for uniformly coating the inner wall of the outer suspension arm is arranged at the bottom of the sliding block; when the sliding block slides on the inner wall of the outer suspension arm, a small amount of air enters the grease storage cavity through the L-shaped pipe, so that liquid lubricating grease in the grease storage cavity slowly drips onto the cloth sleeve along with the discharging pipe and the spray head, and in the process that the cloth sleeve rolls on the inner wall of the outer suspension arm, the cloth sleeve evenly smears the liquid lubricating grease on the inner wall of the outer suspension arm. After the liquid lubricating grease is cooled on the advancing route of the sliding block to form paste, the edge of the sliding block is protected, and the protection efficiency of the sliding block is guaranteed.

    本发明涉及一种起重机吊臂的润滑脂加注机构,包括外吊臂和内吊臂,所述内吊臂活动设置在外吊臂的内部,所述内吊臂的两侧外壁上均固定安装有滑块,所述滑块的内部开设有储脂腔,两个所述滑块均与外吊臂的内壁滑动连接,所述滑块的顶部活动设置有注料机构,所述滑块的底部设置有用于给外吊臂内壁均匀涂料的上料机构;当滑块在外吊臂内壁上滑动时,储脂腔内通过L形管进入少量的空气,使得储脂腔内的液态润滑脂将随着出料管和喷头缓慢滴落到布套上,在布套在外吊臂内壁上滚动的过程中,布套将液态润滑脂均匀涂抹到外吊臂内壁上,液态润滑脂在滑块行进路线上受冷形成膏状后,对滑块的边缘处提供保护,保证了对滑块的保护效率。
