The invention relates to the technical field of hoisting equipment, and discloses crane jib self-lubricating equipment. The equipment comprises a large hoisting arm, an extrusion assembly, a small hoisting arm, an oil injection assembly and a clamping ring, wherein a lubricating storage cavity is formed in the inner wall of the large hoisting arm, the inner wall of the lubricating storage cavity is movably connected with the outer wall of the extrusion assembly, the inner wall of the large hoisting arm is movably connected with the outer wall of the small hoisting arm, and an arc-shaped clamping groove is formed in the left side of the small hoisting arm. According to the crane jib self-lubricating equipment, the small hoisting arm is matched with the arc-shaped clamping groove to drive clamping balls to move and drive rigid coil springs to move together, toothed bars are matched with toothed grooves to enable the rigid coil springs to be in an extruded state, at the moment, oil nozzles are extruded to move in the earlier stage until the oil nozzles move to the maximum extent, the oil injection assembly starts to inject oil, meanwhile the movement of the small hoisting arm is matched with an annular threaded groove and rolling balls, the periphery of the joint of the large hoisting arm and the small hoisting arm is evenly lubricated under the driving of the clamping ring, and therefore the automatic lubricating effect of a crane jib is achieved.

    本发明涉及起重设备技术领域,且公开了一种起重机吊臂自润滑设备,包括起重大臂、挤压组件、起重小臂、注油组件和卡环,所述起重大臂的内壁开设有润滑存储腔,所述润滑存储腔的内壁与挤压组件的外壁活动连接,所述起重大臂的内壁与起重小臂的外壁活动连接,所述起重小臂的左侧开设有弧形卡槽,该一种起重机吊臂自润滑设备,通过起重小臂配合着弧形卡槽带动着卡球移动以及刚性卷簧一同移动,齿杆配合着齿槽使刚性卷簧处于挤压状态,此时油嘴前期受到挤压移动,直至移动最大限度后注油组件开始注油,同时起重小臂的移动配合着环形螺纹槽以及滚球在卡环的带动下,使起重大臂与起重小臂的结合处四周均匀润滑,从而实现了起重机吊臂自动润滑的效果。
