[0019] Combined with appendix Figures 1-6 The high-altitude pole climbing and lifting device includes two lifting boxes 11 distributed vertically. Each lifting box 11 is equipped with a clamping assembly 50, which is used to clamp the utility pole tower and move along it. Each clamping assembly 50 includes two symmetrically arranged rotating shafts 30, which are rotatably disposed within the lifting box 11. An upper clamping jaw 28, a middle clamping jaw 31, and a lower clamping jaw 33 are fixedly disposed on each rotating shaft 30. The middle clamping jaw 31 is located between the upper clamping jaw 28 and the lower clamping jaw 33. A half gear 41 is fixed inside the upper clamping jaw 28. Each half gear 41 meshes with a gear 42. The gear 42 is rotatably disposed within the lifting box 11. The two gears 42 mesh with each other. One of the gears 42 meshes with an output gear 43. The output gear 43 is fixed to the motor shaft of a first motor 44, which is fixedly disposed within the lifting box 11. It should be noted that the two upper jaws 28 are symmetrically arranged, and the two lower jaws 33 are symmetrically arranged. A first guide wheel 29 is rotatably installed on the upper jaw 28, and a second guide wheel 34 is rotatably installed on the lower jaw 33. The first guide wheel 29 and the lower jaw 33 play an auxiliary guiding role after they are in contact with the power pole tower. It should be noted that the two middle jaws 31 are symmetrically arranged, and a clamp 32 is fixedly installed at the end of the middle jaws 31. The clamp 32 is used to provide more friction after it is attached to the power pole tower. A power wheel 26 is installed inside the upper lifting box 11. The power wheel 26 is driven by a power component. After the power wheel 26 is in contact with the power pole tower, the power component drives the power wheel 26 to rotate, thereby driving the upper lifting box 11 to rise along the power pole tower. The power assembly includes a second motor 49 fixedly mounted on the upper lifting box 11. The motor shaft of the second motor 49 is fixed to a worm gear 46, which meshes with a worm wheel 47. The worm wheel 47 is fixed on a rotating shaft 48, which is rotatably mounted inside the upper lifting box 11. The power wheel 26 is fixed to the rotating shaft 48. After the second motor 49 is started, it drives the worm gear 46 to rotate. The meshing of the worm gear 46 with the worm wheel 47 drives the worm wheel 47 to rotate, and the worm wheel 47 drives the coaxial power wheel 26 to rotate. An auxiliary wheel 27 is rotatably installed inside the lower lifting box 11. The auxiliary wheel 27 is not powered and is used to assist rotation. Both the power wheel 26 and the auxiliary wheel 27 are large-sized rubber wheels with patterns to increase friction and prevent slippage.

[0020] A cable box 14 is fixedly installed at the bottom of the upper lifting box 11. A cable wheel 16 is rotatably installed inside the cable box 14. A cable 17 is wound on the cable wheel 16. The end of the cable 17 is fixed to the lower lifting box 11. The cable wheel 16 is connected to the motor shaft of the third motor 15. The third motor 15 is fixed to the cable box 14. After the No. 3 motor 15 starts, it drives the cable reel 16 to rotate. After the cable reel 16 rotates, it releases a sufficient amount of cable 17. Then, the upper lifting box 11 first goes up the power pole tower to the top. After completion, the No. 3 motor 15 starts, the cable reel 16 winds the cable 17, and drives the lower lifting box 11 to the top. It should be noted that a base plate 10 is fixed on the lower lifting box 11, and a seat 13 is fixed on the base plate 10. The electrician sits on the seat 13. After the upper lifting box 11 drives the lower lifting box 11 to rise, it also drives the electrician on the lower lifting box 11 to rise together, thus providing great convenience for the electrician. To facilitate movement, wheels 12 are installed on the bottom of the lower lifting box 11 and the bottom of the base plate 10. The wheels 12 have a built-in locking structure and can be locked as support when not moving.

[0021] An electrical control box 45 is fixedly installed in each of the two lifting boxes 11, and the electrical control box 45 is used for electrical control. Example

[0022] See Figure 4 The difference from Embodiment 1 is that a top box 18 is fixedly installed on the upper lifting box 11. Rotating rod 1 37 and rotating rod 2 39 are rotatably installed inside the top box 18. A drive gear 38 is fixed on rotating rod 1 37, and a transmission gear 40 is fixed on rotating rod 2 39. The drive gear 38 meshes with the transmission gear 40. Rotating rod 1 37 is fixed to the motor shaft of motor 4 19. Motor 4 19 is fixed to the top box 18. Several hook rods 1 20 are fixed on rotating rod 1 37, and several hook rods 21 are fixed on rotating rod 2 39. The hook rod 1 20 and hook rod 21 are staggered. When the upper lifting box 11 moves to the position of the crossarm of the power pole, the fourth motor 19 starts. The fourth motor 19 drives the rotating rod 37 to rotate, which in turn drives the drive gear 38 to rotate. Through the meshing of the drive gear 38 and the transmission gear 40, the rotating rod 29 is driven to rotate. The rotation of the rotating rod 1 37 and the rotating rod 29 causes the hook rod 1 20 and hook rod 21 to move closer to each other. The hook rod 1 20 and hook rod 21 have an L-shaped structure, which is used to hold the two sides of the crossarm of the power pole. After the hook rod 1 20 and hook rod 21 hold the two sides of the crossarm of the power pole, they provide support for the upper lifting box 11 and the subsequent lower lifting box 11 to lift the electrician, which greatly improves safety. A first slot 35 is provided on the top box 18 to allow the hook rod 20 to move, and a second slot 36 is provided on the top box 18 to allow the hook rod 21 to rotate. The crossarms of utility poles are designed to provide support far exceeding the weight of a normal adult, which is sufficient to ensure safety. A placement plate 24 is also fixed on one side of the top lifting box 11. A camera 25 is fixedly installed on the placement plate 24. Through the camera 25, the electrician can determine whether the top lifting box 11 has moved to the designated position of the crossarm of the utility pole. Anti-slip pad 22 is fixed inside the hook rod 21, and anti-slip pad 23 is fixed inside the hook rod 20. The anti-slip pad 22 and the anti-slip pad 23 are used to increase friction and prevent slippage. Pressure sensors are fixedly installed inside the anti-slip pad 23 and the anti-slip pad 22 to ensure that the hook rod 20 and the hook rod 21 are completely hooked on the crossarm of the power pole tower.

[0023] How to use: The electrician places the two lifting boxes 11 against the crossarm of the utility pole. After completion, the electrician controls the first motor 44 to start via the electrical control box 45. The first motor 44 drives the output gear 43 to start. Through the meshing of the output gear 43 and the gear 42, the gear 42 is driven to rotate. The meshing and rotation of the gears 42 drives the two rotating shafts 30 to rotate. The rotating shafts 30 drive the upper clamp 28, the rotating shafts 30 and the lower clamp 33 to rotate to clamp the utility pole. After clamping, the electrician drives the No. 3 motor 15 to rotate via the control box 45. The No. 3 motor 15 drives the cable reel 16 to rotate, and the cable reel 16 releases a sufficient amount of cable 17. After completion, the electrician drives the No. 2 motor 49 to start via the control box 45. The No. 2 motor 49 drives the worm gear 46 to rotate. The meshing of the worm gear 46 with the worm wheel 47 drives the worm wheel 47 to rotate. The worm wheel 47 drives the rotating shaft 48 to rotate, and the rotating shaft 48 drives the power wheel 26 to rotate. The power wheel 26 drives the upper lifting box 11 to rise along the power pole tower. During the process, the electrician observes the image transmitted back by the camera 25 to determine that the upper lifting box 11 has moved to the position of the crossarm of the power pole. The electrician drives the fourth motor 19 to start through the electrical control box 45. The fourth motor 19 drives the rotating rod 37 to rotate, which drives the drive gear 38 to rotate. The meshing of the drive gear 38 and the transmission gear 40 drives the rotating rod 39 to rotate. The rotation of the rotating rod 37 and the rotating rod 39 causes the hook rod 20 and the hook rod 21 to move closer to each other. The hook rod 20 and the hook rod 21 have an L-shaped structure and are used to hold the two sides of the crossarm of the power pole. The pressure sensor inside the second anti-slip pad 23 and the first anti-slip pad 22 provides feedback on the pressure. When the pressure is insufficient, it means that the second anti-slip pad 23 and the first anti-slip pad 22 are not properly engaged. The electrician controls the upper lifting box 11 to descend until the pressure detected by the pressure sensor inside the second anti-slip pad 23 and the first anti-slip pad 22 reaches the set value. After completion, the upper lifting box 11 is locked, the electrician sits on the seat 13 and controls the No. 3 motor 15 to start. When the No. 3 motor 15 starts, the cable wheel 16 winds the cable 17, which moves the lower lifting box 11 and the electrician to the top of the power pole tower, allowing the electrician to carry out the work. After completion, the electrician controls the No. 3 motor 15 to start, the cable reel 16 releases the cable 17, and moves the lower lifting box 11 and the electrician to the bottom of the power pole tower; Then, the electrician controls the top lifting box 11 to rise until the pressure sensor inside the anti-slip pad 23 and the anti-slip pad 22 reports no pressure. After completion, the electrician controls the fourth motor 19 to rotate through the electrical control box 45. The rotation of the fourth motor 19 drives the hook rod 21 and the hook rod 20 to reset. Then, the electrician controls the top lifting box 11 to descend and reset.
