CN-121972879-A - Welding manipulator for high-altitude operation

Abstract

The invention discloses a welding manipulator for high-altitude operation, wherein one end of a mechanical arm is fixedly arranged at the output end of a stabilizing disc, a welding head is arranged at the free end of the mechanical arm, the stabilizing disc is a multi-level linkage stabilizing device, and temporary strength supplement is carried out on a failed stabilizing mode while the next-level stabilizing mode is triggered to take effect through failure of the high-priority stabilizing mode. The device adopts a multistage vacuum structure to fail slowly, reduces the pressure of a fastener, and simultaneously improves the monitoring performance of device installation failure. In the slow failure of the vacuum internal structure, the linear enhancement sealing effect of the elastic sleeve is kneaded based on the stretching action, so that the vacuum stretching is ensured, and the closer the device is to the installation failure, the higher the tightness of the device is. The overhead operation controllability and the safety of the whole device are improved.
