[0051] Specifically, the self-lifting assembly includes a mounting base 1, the front part of which is hinged with two telescopic links 21, the ends of the telescopic links 21 are connected to semicircular clamping arms 2, the ends of the two clamping arms 2 are provided with mutually adapted locking mechanisms 23, the inner ring side walls of the two clamping arms 2 are provided with multi-speed clamping assemblies 4, and the outer ring side walls are symmetrically provided with two driving rotors 3, the top of the mounting base 1 is provided with a visual positioning sensor 6, and the inside of the mounting base 1 is provided with a controller electrically connected to the telescopic link 21, the multi-speed clamping assembly 4, the driving rotor 3, and the visual positioning sensor 6, and the wiring robotic arm 5 is arranged on the top of the mounting base 1 and electrically connected to the controller.

[0052] The mounting seat 1 is provided with hinge grooves 12 on both sides of the front part, and the telescopic connecting rod 21 is hinged to the hinge grooves. The two clamping arms form a clamping ring arranged around the outer periphery of the pole under the connection of the locking mechanism 23. The multi-speed clamping assembly 4 is used to slide and clamp the pole, constrain and assist the mounting seat 1 and the clamping arm 2 to rise and fall and rotate along the pole under the drive of the driving rotor 3, thereby driving the wiring robot arm 5 to rise and fall and rotate. The wiring robot arm clamps the plug of the test cable and connects the plug to the feeder terminal socket when it moves to the bottom of the corresponding socket of the feeder terminal. The visual positioning sensor 6 is used to collect images and perform image recognition, identify the corresponding socket and locate the relative position of the socket and the present application.

[0053] Specifically, the driving rotor 3 includes an extension arm 31 connected to the clamping arm 2 , a main driving motor 32 is vertically embedded at the end of the extension arm 31 , and a rotor body 33 is sleeved on the output shaft of the main driving motor 32 .

[0054] This application simulates the principle of a multi-rotor drone through symmetrically arranged driving rotors 3 to achieve the lifting and rotation of the wire rod along the wire rod. When the clamping arm 2 slides to clamp the wire rod, the rotor bodies 31 of the two driving rotors 3 rotate at the same speed to achieve the lifting and lowering of the clamping arm 2, and the rotor bodies 31 of the two driving rotors 3 rotate at a differential speed to achieve the rotation of the clamping arm 2 around the wire rod.

[0055] Specifically, the multi-speed clamping assembly 4 includes several telescopic assemblies 41 embedded in the inner ring side wall of the clamping arm 2, and the end of the telescopic shaft of the telescopic assembly 41 is connected to a multi-speed clamping block 42. The multi-speed clamping block 42 slides toward the center of the circular space surrounded by the clamping arm 2 and is embedded with a lifting clamping block 421, a parking clamping block 422, and a rotating clamping block 423. A driving mechanism is provided inside the multi-speed clamping block 42 for driving the lifting clamping block 421, the parking clamping block 422, and the rotating clamping block 423 to alternately extend and retract.

[0056] The end of the lifting clamping block 421 is provided with a clamping wheel that rotates along a vertical plane, the end of the parking clamping block 422 is provided with an elastic friction plate, and the end of the rotating clamping block 423 is provided with a clamping wheel that rotates along a horizontal plane;

[0057] The telescopic components 41 are evenly distributed along the center of the circular space surrounded by the clamping arm 2 .

[0058] When it is necessary to drive the rotor 3 to drive the clamping arm 2 and the mounting seat 1 to perform a lifting movement, the driving mechanism inside the multi-speed clamping block 42 causes the lifting clamping block 421 to protrude, and the telescopic assembly 41 drives the multi-speed clamping block 42 to move toward the wire rod. The clamping wheel of the lifting clamping block 421 contacts the wire rod, driving the rotor 3 to drive the clamping arm 2 and the mounting seat 1 to lift and lower. When it is necessary to drive the rotor 3 to drive the clamping arm 2 and the mounting seat 1 to perform a rotating movement, first control the driving rotor 3 to make the present application in a hovering state, and the driving mechanism inside the multi-speed clamping block 42 causes the lifting clamping block 421 to retract and the rotating clamping block 423 to protrude, so that the clamping of the rotating clamping block 423 The holding wheel contacts the wire rod, driving the rotor 3 and then driving the clamping arm 2 and the mounting seat 1 to rotate around the wire rod; when the visual positioning sensor determines the position of the feeder terminal socket and the driving rotor 3 drives the wiring robot arm 5 to move to the bottom of the corresponding socket, the driving rotor 3 is first controlled to make the present application in a hovering state, and then the driving mechanism inside the multi-speed clamp 42 is controlled to make the lifting clamp 421 or the rotating clamp 423 retract and the parking clamp 422 protrude, so that the elastic friction plate contacts the outer periphery of the wire rod, so that the clamping arm 2 is fixedly connected to the wire rod, the driving rotor 3 is stopped and then the wiring robot arm 5 is controlled to connect the test cable plug and the feeder terminal socket.

[0059] The present application drives the control logic of the rotor 3. Specifically, when the rotor 3 is driven to drive the clamping arm 2 and the mounting seat 1 to move up and down, the multi-speed clamping assembly 4 clamps the wire rod through the lifting clamp 421, and the clamping wheel rotating along the vertical plane at the end of the lifting clamp 421 contacts the wire rod, so that the present application can ignore the horizontal rotational force brought to the clamping arm 2 due to the speed error of the driving rotor 3, wind force, etc., thereby simplifying the lifting control logic; similarly, the present application simplifies the control logic when the driving rotor drives the clamping arm 2 and the mounting seat 1 to rotate through the rotating clamp 423, and simplifies the control logic when the driving rotor 3 drives the clamping arm 2 and the mounting seat 1 to hover through the parking clamp 422, thereby simplifying and optimizing the control logic of the present application for simulating the movement of a multi-rotor drone.

[0060] Preferably, the multi-speed clamp 42 is symmetrically provided with two groups of clamping blocks consisting of a lifting clamp 421, a parking clamp 422, and a rotating clamp 423 from top to bottom, and the lifting clamp 421, the parking clamp 422, and the rotating clamp in the two groups are symmetrically arranged up and down.

[0061] The design of the double clamping block group facilitates strengthening the stability of the connection between the multi-stage clamping blocks 42.

[0062] Specifically, a driving cavity is provided inside the multi-speed clamping block 42, and a plurality of telescopic slide grooves that penetrate the driving cavity are opened on the side of the multi-speed clamping block 42 toward the center of the circular space surrounded by the clamping arm 2. The lifting clamping block 421, the parking clamping block 422, and the rotating clamping block 423 are respectively slidably set in the telescopic slide groove, and the side wall of the telescopic slide groove is provided with a buffer groove. The lifting clamping block 421, the parking clamping block 422, and the rotating clamping block 423 are provided with a protrusion that is slidably set in the buffer groove on one side, and a buffer spring 427 is provided between the two sides of the protrusion and the side wall of the buffer groove; a clamping motor 424 is embedded in the top of the driving cavity, and the bottom end of the clamping motor 424 is connected to a driving shaft 425, and the end of the driving shaft 425 is rotatably set at the bottom of the driving cavity, and a plurality of push-pull cams 426 are respectively provided on the driving shaft 425, which respectively contact the lifting clamping block 421, the parking clamping block 422, and the rotating clamping block 423.

[0063] The rotation of the clamping motor 424 drives the drive shaft 425 to rotate and then drives the push-pull cams 426 to rotate, thereby pushing the lifting clamp 421, the parking clamp 422, and the rotating clamp 423 to overcome the buffer spring 427 to extend, or retract under the action of the buffer spring 427. By designing the shape of each push-pull cam 426 and the initial contact position with the lifting clamp 421, the parking clamp 422, and the rotating clamp 423, the alternating extension and retraction of the lifting clamp 421, the parking clamp 422, and the rotating clamp 423 can be achieved.

[0064] Specifically, the locking mechanism 23 is a mechanical locking mechanism or an electric locking mechanism electrically connected to the controller, such as Figures 5 to 8 As shown, this embodiment shows a bolt connection structure.

[0065] A battery compartment 22 is provided on one side of the clamping arm 2 close to the locking mechanism 23. A battery pack is provided in the battery compartment 22. The battery pack is used to power the various components of the self-lifting wiring robot of this application.

The sensing part of the ultrasonic ranging sensor 7 faces downward and is used to measure the height of the self-lifting wiring robot from the ground. Furthermore, a gyroscope is also provided inside the mounting base to facilitate the detection of the posture of the self-lifting wiring robot, improve the grasp of the position and posture of the self-lifting wiring robot, and also to assist the visual positioning operation of the visual positioning sensor 6.

[0067] Specifically, the wiring robot arm 5 includes a lifting rod 51 vertically arranged on the top of the mounting base 1, and a wire clamping assembly 52 is provided at the top of the lifting shaft of the lifting rod 51; the wire clamping assembly 52 includes a mounting plate 521 connected to the top of the lifting shaft of the lifting rod 51, and the mounting plate 521 is provided with a wire clamping groove away from the lifting rod 51, and a wire clamp 522 is provided on the side wall of the wire clamping groove; the wire clamp 522 includes a wire clamping telescopic mechanism symmetrically embedded in the side wall of the wire clamping groove, and an arc-shaped clamping block is provided at the end of the wire clamping telescopic mechanism.

[0068] When the driving rotor 3 drives the wiring robot arm 5 to lift and rotate to the corresponding position below the socket of the feeder terminal, the multi-speed clamping assembly 4 switches the parking clamp block 422 to fix the clamping arm 2 to the wire rod, and the controller operates the telescopic link 21 to extend and retract, so that the wire clamp 522 holding the test cable plug is moved to the bottom of the feeder terminal socket, and the lifting rod 51 drives the wire clamp 522 to move upward and plug into the corresponding socket. Correspondingly, the lifting rod 51 drives the wire clamp 522 to move downward to drive the plug to separate from the corresponding socket.

[0069] Preferably, a wire-releasing groove 11 for releasing wires is provided on a side of the mounting seat 1 away from the clamping arm 2 .

[0070] The test cable plug is a round aviation plug. The arc-shaped clamping block clamps the lower side of the round aviation plug so that the upper part of the plug is exposed from the mounting plate 521.

[0071] Aviation plugs typically feature a rotatable threaded sleeve with a rack strap installed on the outside for manual tightening. To ensure a more secure test cable connection, the aviation plug's threaded sleeve must be tightened to the threaded connection on the socket. A tightening mechanism 523 is also located on the top of the mounting plate 521. This tightening mechanism 523 includes a displacement rail mounted on the top of the mounting plate 521. The slider on this displacement rail is equipped with a tightening and telescoping mechanism. This mechanism extends toward the cable clamping slot, and its telescoping shaft is terminated by a tightening block. A tightening rack is located on the side of the tightening block away from the tightening and telescoping mechanism.

[0072] The rotating telescopic mechanism drives the tightening pressure block to contact the threaded connection sleeve outside the plug, the rotating rack contacts the rack belt of the threaded connection sleeve, the displacement guide rail drives the tightening pressure block to move, and then drives the threaded connection sleeve to rotate, thereby tightening the threaded connection sleeve and the threaded connection part on the socket.

[0073] The controller is a single chip microcomputer or other industrial control computer, the telescopic connecting rod 21, the telescopic assembly 41, the lifting rod 51, and the rotating telescopic mechanism can be electric cylinders, and the displacement guide rail is an electric guide rail.

[0076] S100: The user holds the two clamping arms 2 and places them around the outside of the corresponding utility pole. The two clamping arms 2 are connected and locked by the locking mechanism. The controller controls the multi-speed clamping assembly 4 to protrude the lifting clamping block 421 and clamp the utility pole.

[0077] S200: The controller controls the driving rotor 3 to start, driving the clamping arm 2 to rise along the rod;

[0078] S300: The visual positioning sensor 6 captures an image of the upper portion of the utility pole, identifies and locates the position of the feeder terminal, and transmits the image to the controller in real time. The controller controls the drive rotor 3 and the multi-speed clamping assembly 4 to switch the ascending and rotating states of the wiring robot until the wiring robot arm 5 moves to the corresponding preset position below the socket of the feeder terminal. The controller controls the multi-speed clamping assembly 4 to extend the parking clamp 421 and clamp the utility pole, and then controls the drive rotor 3 to stop.

[0079] S400: The controller controls the telescopic link 21 to extend and retract, so that the wiring robot arm 5 moves to the position directly below the feeder terminal socket. The wiring robot arm 5 plugs the clamped test cable plug into the corresponding socket.
