The invention belongs to the technical field of suspension arm stretching and retracting, and particularly relates to a novel heavy-load telescopic suspension arm. Compared with the prior art, a two-section guide rail is fixed to the outer surface of the periphery of a two-section arm through screws, a three-section guide rail is fixed to the outer surface of the periphery of a three-section arm through screws, a sliding block combination is placed in grooves of a first-section sliding block holder and a second-section sliding block holder and keeps making contact with the guide rails, and the tail of a cylinder body of a telescopic oil cylinder is fixed to a valve set; and the head of a piston rod is fixedly connected to the interior of the three-section arm, stretching and retracting of the telescopic arm are achieved through stretching and retracting movement of the telescopic oil cylinder, the sliding block combination is placed in the grooves of the first-section sliding block holder and the second-section sliding block holder and keeps making contact with the guide rails, in the sliding block combination, a sliding block is placed in a groove in the middle of a cushion block, a jackscrew is connected to the sliding block through threads, the overall height of the sliding block combination can be adjusted by screwing the jackscrew, and therefore adjustment of the gap between the inner wall of a one-section arm and the two-section guide rail is achieved.
本发明属于吊臂伸缩的技术领域,具体涉及的是一种新型重载可伸缩吊臂。相对于现有技术,本发明二节导轨通过螺钉固定在二节臂四周外表面,三节导轨通过螺钉固定在三节臂四周外表面,滑块组合放置在一节滑块保持架和二节滑块保持架的槽内,且与导轨保持接触,伸缩油缸的缸体尾部固定在阀组上,活塞杆头部固连在三节臂的内部,通过伸缩油缸的伸缩运动,实现伸缩臂的伸缩,滑块组合放置在一节滑块保持架和二节滑块保持架的槽内,且与导轨保持接触,滑块组合中,滑块放置在垫块中间的凹槽内,顶丝通过螺纹连接在滑块上,通过拧动顶丝可调节滑块组合整体的高度,从而实现对一节臂内壁与二节导轨之间间隙的调节。
