Outdoor live working robot mechanical arm capable of automatically switching tools

Abstract

The invention discloses an outdoor live working robot mechanical arm capable of automatically switching tools. The outdoor live working robot mechanical arm capable of automatically switching the tools comprises a mechanical large arm, a mechanical small arm and a mechanical forearm, wherein the mechanical large arm, the mechanical small arm and the mechanical forearm are sequentially connected through joints; the mechanical forearm comprises an insulating rod and a tool butt joint, and a butt joint groove is formed in the side wall of the tool butt joint; a live working tool assembly comprises a connecting part and a tool part which are arranged up and down, wherein the connecting part comprises a connecting seat and a sleeving ring on the connecting seat; and the side wall of the sleeving ring is provided with a rotating piece, the inner side and the outer side of the rotating piece are respectively connected with a locking block and a shifting claw block, and a driving assembly drives the shifting claw block to rotate to realize locking and loosening switching of the locking block and the butt joint groove. By means of a tool butt joint device at the tail end of the mechanical arm, butt joint grabbing of different live working tool assemblies is realized, automatic replacement of the live working tools is realized, the structure is simple, the operation is convenient, and the working efficiency is effectively improved.

Description

technical field [0001] The invention designs a mechanical arm of an outdoor live working robot that realizes automatic switching of tools, and belongs to the technical field of outdoor live working robot design. Background technique [0002] At present, the widely used live working technology is mainly manual live working, which requires operators to climb high-voltage iron towers or use insulated arm trucks to carry out non-power-off work. However, manual live work means that the operator must be in a dangerous environment with high altitude, high voltage, and strong electromagnetic field. The labor intensity is high, and the posture of the human body is difficult to control. A little carelessness is prone to personal injury and death accidents. In order to solve the dangers caused by manual live work and improve work efficiency, live work technology using robots instead of manual work has emerged at home and abroad. [0003] The research results of the live working robot ...
