The invention discloses a large-tonnage hydraulic telescopic suspension arm, and relates to the technical field of telescopic suspension arms, the large-tonnage hydraulic telescopic suspension arm comprises a first basic arm, a basic arm telescopic mechanism is arranged in the first basic arm, and the basic arm telescopic mechanism can control a second basic arm, a third basic arm and a fourth basic arm to stretch out and draw back at the same time, so that the suspension arm can stretch out and draw back rapidly. A dust cleaning mechanism is arranged outside the second basic arm, the dust cleaning mechanism comprises a second threaded rod arranged outside the second basic arm, a cleaning plate is in threaded connection with the outside of the second threaded rod, and when the lifting arm is contracted to be placed after use, the cleaning plate can be conveniently cleaned; the basic arm telescopic mechanism moves to drive a second rotating shaft to rotate, a third rotating shaft can be driven to rotate through a belt, finally, a sweeping plate can drive a sweeping brush to clean the surface of the second basic arm, impurities accumulated on the surface in the working process of the suspension arm are conveniently removed, abrasion of the suspension arm is reduced, and the service life of the suspension arm is prolonged. The normal function and the service life of the suspension arm are ensured.
本发明公开了一种大吨位液压伸缩式吊臂,涉及伸缩式吊臂技术领域,包括第一基本臂,第一基本臂的内部设有基本臂伸缩机构,基本臂伸缩机构可以控制第二基本臂、第三基本臂和第四基本臂同时发生伸缩,便于吊臂快速伸缩,便于快速响应和高效率作业,第二基本臂的外部设有灰尘清理机构,灰尘清理机构包括设置在第二基本臂外部的第二螺纹杆,第二螺纹杆的外部螺纹连接有清扫板,在使用完后将吊臂收缩放置时,基本臂伸缩机构移动会带动第二转动轴发生转动,通过皮带可以带动第三转动轴发生转动,最终可以使清扫板带动清扫毛刷对第二基本臂的表面进行清理,便于清除吊臂工作过程表面积聚的杂质,减小吊臂的磨损,保证吊臂的正常功能和使用寿命。
