Description

Technical Field

[0001] The invention relates to the technical field of live working, and in particular to a live working insulation protection device for a lightweight auxiliary working robot arm. Background Art

[0002] Using a lightweight auxiliary operation robotic arm to operate the insulating short rod has become a common technical means in live distribution network operations. Operators can operate the insulating short rod through the robotic arm without having to approach the live body directly, and can maintain a farther safe distance to reduce the risk of electric shock. In addition, the robotic arm has high precision and stability, and can accurately operate the insulating short rod according to preset procedures and instructions, avoiding operational errors caused by human factors. At the same time, the robotic arm bears most of the weight and force of operating the insulating short rod, and operators do not need to hold the insulating short rod for a long time to operate, which reduces physical exertion and labor intensity.

[0003] However, the existing lightweight auxiliary operation robot arm still has the following disadvantages when in use: 1. The robot arm needs to ensure a certain insulation strength when working with electricity to achieve the insulation protection function. The existing technology is to install an insulating rod at the end of the robot arm and connect the pneumatic clamp through the insulating rod. However, the length of the insulating rod will increase the load of the robot arm. To solve this problem, the existing technology will add insulators to the insulating rod to increase the creepage distance to ensure the effective insulation length while reducing the length of the insulating rod. However, the skirt structure used by the existing insulators is mostly a simple annular structure. Therefore, it is necessary to design multiple sets of skirt structures to make the creepage distance meet the requirements. It will still occupy a long length in space, making it difficult to further reduce the length of the insulating rod. In addition, the skirt structure is more susceptible to contamination, which affects the insulation performance. The impact is greater; 2. The robotic arm needs to be carried on the working bucket of the insulated bucket truck when in use. In the prior art, there are two common fixing methods. One is to directly hang and fix the robotic arm on the outer wall of the working bucket. This method will increase the lateral size of the working bucket. When working in a narrow space, it is difficult to flexibly approach the target position. For example, in the narrow power line maintenance scene in urban streets, it may be impossible to work due to insufficient space. The second is to fix the robotic arm on the top of the working bucket. However, this method will make it impossible for the working bucket to carry operators when manual work is required, thereby limiting the flexibility of equipment use; 3. Most of the joints of the robotic arm are designed with sealing structures, but the existing sealing structures are inconvenient to replace. The entire robotic arm needs to be disassembled for replacement and maintenance, which increases the difficulty and workload of maintenance. Summary of the invention
