[0002] In the field of live-line work without power interruption, the insulated rod method is widely used in distribution network live-line work due to the high safety and distance between the workers and the live conductor. Among these, live-line disconnection of conductors is the most frequently performed operation in distribution network live-line work, generally accounting for more than 70% of the workload. During conductor disconnection, to prevent conductor slippage, auxiliary personnel need to fix both ends or one end of the cut section before the main operator performs the work. This requires at least two workers for conductor disconnection, resulting in limited space in the insulated hopper. Furthermore, some operations require using the insulated rod to support heavy tools, placing stringent demands on the workers' physical strength.

[0022] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, a live-line working auxiliary robotic arm includes an integrated control module 1, a gripping base 2, a horizontal movement module 6, a pitch joint module, a swing joint module, and a telescopic module.

[0024] The clamping base 2 is used to fix the robotic arm to the insulating bucket. The clamping base 2 has a U-shaped cross-section and is equipped with multiple movable pressure heads 9 and multiple fixed pressure heads 10. The ends of the movable pressure heads 9 and fixed pressure heads 10 are made of rubber and are used to clamp onto the guardrail of the insulating bucket to increase friction and make the clamping more secure. Specifically, the movable pressure heads 9 and fixed pressure heads 10 are located on the inner side of the clamping base 2, and the fixed pressure heads 10 are fixedly connected to the clamping base 2. Each movable pressure head 9 is connected to a hand-tightening bolt 8, which passes through one side of the clamping base 2 and is threaded to the clamping base 2. Thus, when the hand-tightening bolt 8 is turned, the movable pressure head 9 can be moved back and forth, thereby fixing the clamping base 2 to the insulating bucket.

[0025] A mounting bracket 14 is fixed on the clamping base 2, and the horizontal moving module 6 is fixed on the mounting bracket 14. Specifically, the horizontal moving module 6 includes a frame, which is fixed on the mounting bracket 14. A fifth motor 13, a horizontal lead screw, a horizontal slide rail, and a moving base are mounted on the frame. The motor drives the horizontal lead screw to rotate, and the interaction force between the horizontal lead screw and the third lead screw sleeve on the moving base drives the moving base to move along the horizontal slide rail. Its working principle is the same as that of the telescopic module, both achieved through a motor, lead screw, slide rail, and third lead screw sleeve. A first dust cover 11 is installed on the upper side of the frame to prevent dust from falling onto the internal track and lead screw, affecting the power transmission effect, and also to provide safety protection for the operator.

[0026] The pitch joint module includes a first motor 3, and the yaw joint module includes a second motor 4. The first motor 3 is mounted on the movable base of the horizontal movement module 6. The output shaft of the first motor 3 is parallel to the travel trajectory of the horizontal movement module 6. A connecting frame 5 is mounted on the output shaft of the first motor 3, and the second motor 4 is mounted on the upper end of the connecting frame 5. The output shafts of the first motor 3 and the second motor 4 are perpendicular to each other. Both the first motor 3 and the second motor 4 are equipped with protective housings. The first motor 3 and the second motor 4 are used to adjust the angle of the telescopic module, thereby enabling adjustment of the telescopic module at any angle.

[0027] like Figure 4As shown, the telescopic module includes a bracket 71, a fourth motor 73, a second lead screw 76, a second slide 78, a third motor 72, a first lead screw 75, and a first slide 77. A second dust cover 12 is mounted on the bracket 71. The third motor 72 and the fourth motor 73 are respectively mounted on the bottom of the bracket 71. The first lead screw 75 and the second lead screw 76 are rotatably connected to the bracket 71 and are parallel to each other. The output shaft of the third motor 72 is connected to the first lead screw 75, and the output shaft of the fourth motor 73 is connected to the second lead screw 76. A second lead screw sleeve is installed on the second slide table 78, and a first lead screw sleeve is installed on the first slide table 77. A first slide rail and a second slide rail are installed on the bracket 71. The first slide table 77 is slidably connected to the first slide rail, and the second slide table 78 is slidably connected to the second slide rail. An insulating rod 74 is fixed on the first slide table 77. A circular hole is opened at the upper end of the bracket 71, through which the insulating rod 74 passes and is slidably connected. A working device 79 is installed at the upper end of the insulating rod 74, and the working device 79 is detachably connected to the insulating rod 74. A first lead screw 75 passes through the inside of the first lead screw sleeve. When the third motor 72 rotates, it drives the first lead screw 75 to rotate. Through the interaction force between the first lead screw 75 and the first lead screw sleeve, the first lead screw sleeve and the first slide table 77 move, thereby driving the insulating rod 74 to move. A housing is mounted on the bracket 71. The first lead screw 75, the first slide table 77, and the first slide rail are all located inside the bracket 71 and the housing, while the second lead screw 76, the second slide table 78, and the second slide rail are all located outside the bracket 71.

[0028] like Figure 4 As shown, the second lead screw 76 passes through the inside of the second lead screw sleeve. The second slide 78 is fixedly connected to the output shaft of the second motor 4, and the insulating rod 74 is perpendicular to the output shaft of the second motor 4. When the fourth motor 73 rotates, it drives the second lead screw 76 to rotate. Because the second slide 78 is fixed, the interaction of forces causes the second lead screw 76 and the entire telescopic module to move along the direction of the second lead screw 76. This makes the working device 79 a two-stage telescopic device with a longer telescopic length.

[0029] In use, the integrated control module 1 controls the operation of the first motor 3 and the second motor 4, enabling rotation of the telescopic module 7 in various angular directions. Simultaneously, the horizontal position of the telescopic module 7 can be adjusted via the horizontal movement module 6. The telescopic module 7 also allows adjustment of the telescopic length of the insulating rod 74 and the working device 79. Furthermore, since the working device 79 is detachably connected to the insulating rod 74, different working devices 79 can be replaced depending on the situation.

Therefore, they should not be construed as limitations on the invention. Furthermore, "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "multiple" means two or more.

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
