The insulating telescopic arm comprises an outer arm, an insulating inner arm and a self-adjusting roller device, and the insulating inner arm is limited in the outer arm and can move and stretch out from the free end of the outer arm in the axial direction. The self-adjusting roller device comprises a pressure cylinder arranged on the outer arm, a piston rod capable of moving up and down in the pressure cylinder, and at least two roller assemblies used for bearing the insulating inner arm. The roller assembly comprises a roller shaft and a roller body, the roller body is used for bearing the insulating inner arm and rotatably arranged on the outer side of the roller shaft in a sleeving mode, and the two ends, extending out of the roller body, of the roller shaft are correspondingly connected with piston rods. Therefore, at least two roller assemblies can be ensured to be uniformly stressed, the wear rate is greatly reduced, the service life of the insulating inner arm is prolonged, and the insulating property of the insulating inner arm is improved.
本发明公开一种绝缘伸缩臂及绝缘斗臂车,绝缘伸缩臂包括外臂、绝缘内臂和自调节滚筒装置,绝缘内臂限位于外臂内并可自外臂的自由端沿轴向移动伸出,自调节滚筒装置包括设置在外臂上的压力缸、可在压力缸内进行上下升降运动的活塞杆以及用于承载绝缘内臂的滚筒组件,滚筒组件的数量为至少两个,并且滚筒组件包括滚筒轴以及用于承载绝缘内臂并可转动地套设于滚筒轴的外侧的滚筒本体,滚筒轴伸出于滚筒本体的两端均对应连接有活塞杆,由于压力缸内的流体介质提供给每个活塞杆的作用力是相等的,从而能够保证至少两个滚筒组件受力均匀,极大地降低了磨损率,提升了绝缘内臂的使用寿命和绝缘性能。
