Description

Technical Field

[0001] This invention relates to the field of power line maintenance technology, and in particular to an intelligent robot for insulation wrapping of 35kV bare conductors. Background Technology

[0002] Currently, in medium- and high-voltage transmission lines, bare conductors are exposed to the external environment for extended periods, making them susceptible to pollution, corrosion, lightning strikes, and other hazards, thus posing safety risks. Traditional insulation wrapping methods largely rely on manual operation, which is inefficient, highly dangerous, and difficult to implement online repair or continuous wrapping. Therefore, there is an urgent need for an intelligent device capable of automatically completing conductor insulation wrapping. Summary of the Invention

[0003] The purpose of this invention is to provide an intelligent robot for wrapping 35kV bare conductors, which can automatically walk on the conductor and complete the continuous wrapping of insulation material, and is suitable for insulation retrofitting of new lines or maintenance of live lines.

[0004] The technical solution adopted in this invention is:

[0005] An intelligent robot for sheathing 35kV bare conductors includes:

[0006] The main frame (1) has a rectangular structure and is equipped with a control module and a power system inside;

[0007] The wire channel frame (2) is located in the middle of the main frame and is used for wires to pass through and be positioned.

[0008] The walking wheel assembly (3) includes an upper pressure wheel (31) and a lower drive wheel (32) for gripping the wire and driving the robot to move along the wire;

[0009] Modular encapsulation head (4), installed at the bottom of the main frame, includes:

[0010] Tape winding module (41) for spiral winding of insulating tape;

[0011] Heat shrink tubing module (42) for automatic tubing and heat shrinking;

[0012] The resin injection molding module (43) is used to inject resin and cure it into shape.

[0013] Quick-locking interface (5) for quick replacement of modular encapsulation heads;

[0014] The sling connector (6) is used to connect to a drone or hoisting equipment.

[0015] The modular encapsulation head can select different encapsulation methods according to the working conditions, and each module can be quickly disassembled and assembled, facilitating maintenance and upgrades.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] To achieve automated insulation wrapping of 35kV bare conductors;

[0018] Supports multiple encapsulation methods to adapt to different environments and materials;

[0019] It can be hoisted onto the guide wire by a drone, making it suitable for high-altitude operations;

[0020] Improve operational efficiency and reduce human risk. Attached Figure Description

[0038] The invention will be further described below with reference to the accompanying drawings.

[0039] like Figure 1 As shown, the robot is hoisted to the wire position by the drone via the hanging connector (6). The wire passes through the wire channel frame (2) and is held by the walking wheel assembly (3) to drive the robot to move along the wire.
