Problems solved by technology

But its disadvantages are: live working tools have various forms and complex structures, and the weight of a single live working tool can reach 5-10kg. It is inconvenient for a single person to grasp with one arm. The tightening stability is poor, which leads to low efficiency of live work, and there is a risk of tools falling and pinching workers
[0004] It can be seen that there is still a large technical deficiency in the high-voltage live working robot in the existing research technology, which has seriously restricted the practical application and promotion of the live working robot in the power grid.

Embodiment 1

[0028] In one or more embodiments, a system for automatically changing tools of a live working robot is disclosed, including: a live working platform 10, on which a working robot arm 12-1 and a tool changing mechanism are respectively arranged; The tool replacement mechanism includes a rotating part and a tool magazine 5 arranged on the rotating part; at least two live working tools are arranged in the tool magazine 5, and each live working tool is provided with a working robot arm 12- 1 One-touch fittings that match the end fittings.

[0029] Exemplary, see figure 1 , the live working platform 10 is respectively equipped with a working robot arm 12-1, a wire clamping robot arm 12-2, a screw guide rail pair 7, a rotating mechanism 8 and a tool magazine 5;

[0030] Wherein, the operation manipulator 12-1 and the wire clamping manipulator 12-2 are connected to the live work platform 10 through the post insulator 9, and one work manipulator 12-1 is installed on each post insulat...

Embodiment 2

[0046] In one or more embodiments, a method for automatic tool replacement of a live working robot is disclosed, including three processes of tool selection, tool positioning and tool replacement.

[0047] 1) Tool selection

[0048] Put the used tools into the tool library 5 sequentially according to the process requirements, code each tool, and select the tool according to the coding of the tool library 5 . Select tool by coding during operation, and the used tool is put back in the original tool storehouse 5 .

[0049] 2) Tool positioning

[0050] According to the instruction received to replace the working tool, match the corresponding working tool through coding;

[0051] Rotate the tool magazine 5 to rotate the corresponding operating tool to the set position;

[0052] 5-position locking of the tool magazine;

[0053] Start the tool replacement mechanism, and drive the motor to rotate forward or reverse to return to the original position. Send the tool selection comm...

Abstract

The invention discloses a system and method for automatic operational tool replacement of a live working robot. The system comprises a live working platform, wherein an operational mechanical arm anda tool replacement mechanism are disposed on the live working platform; the tool replacement mechanism comprises a rotation part and a tool library disposed on the rotation part; and at least two types of live working tools are disposed in the tool library, and a quick-replacement joint matched with a tail end joint of the operational mechanical arm is disposed on each live working tool. The system and method disclosed by the invention have the beneficial effects that the disk-type quick-replacement joint replacement tool is adopted; the tools can be locked and positioned through quick pullingand insertion; and an independent quick replacement function of the operational tools of the live working robot can be realized.

Description

technical field [0001] The invention relates to the technical field of high-voltage live working robots, in particular to a system and method for automatically changing working tools for a live working robot. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Distribution network live work robots are mainly used to complete tasks such as stripping insulated wires, disconnecting drain wires with power, removing foreign objects, replacing drop insurance, pruning branches, replacing cross arms, and replacing transformers. In order to improve the automation level and safety of live work, To reduce the labor intensity of operators and the personal threat of strong electromagnetic fields to operators, since the 1980s, domestic and foreign power companies have successively carried out research on live working robots. Operators work on live working p...
