[0002] Transmission and distribution line towers are the core supporting structures of the power transmission and distribution links in a power system. They are mainly used for overhead laying of high-voltage or low-voltage transmission and distribution conductors, lightning protection wires, and related accessories to achieve safe and efficient transmission and distribution of power from substations to users. The towers can withstand the tension of the conductors and can limit the scope of accidents at line segmentation points or in the event of a fault. Angle towers are used at line turning points to adapt to different line routes. Terminal towers are installed at the beginning or end of the transmission and distribution line, connecting substations or user-side equipment. In addition, auxiliary components such as ladders and grounding devices are installed on the towers to facilitate inspection and maintenance work by operation and maintenance personnel, while ensuring the safety performance of the towers and lines in terms of lightning protection, wind resistance, and anti-icing. They are critical infrastructure for ensuring the stable operation of the transmission and distribution network.

At the same time, a more stable fixing method is adopted to ensure the stability of the device during the lifting of heavy objects. It effectively avoids jamming, shaking, and other situations, thereby ensuring the stability and safety of lifting heavy objects.

[0018] In this embodiment, bolt 5 is slidably connected to ring 2, and bolt 5 is threadedly connected to ring 3. One end of rope 11 passes through wheel 2 17, wheel 3 16 and wheel 1 15 in sequence. The output shaft of motor 12 is tightly welded to rope take-up roller 13. The bottom end of threaded rod 4 passes through two rings 3. One end of four bolts 5 passes through both sides of two rings 2 and two rings 3 respectively, ensuring that under the action of the thread, the rotating bolts 5 can fix rings 2 and 3 together.

[0019] In this embodiment, the threaded rod 4 is threadedly connected to the two rings 2, and the rotating wheel 15 is rotatably connected to the fixed rod 6. This ensures that the two rings 2 can be fixed by rotating the threaded rod 4 under the action of the thread, and that the rotating wheel 15 can rotate normally on the fixed rod 6.

[0020] In this embodiment, the first rotating wheel 15 is rotatably connected to the first baffle 7, and the second rotating wheel 17 is rotatably connected to the second fixed rod 18, ensuring that the first rotating wheel 15 can rotate normally on the first baffle 7 and that the second rotating wheel 17 can rotate normally on the second fixed rod 18.

[0021] In this embodiment, the second rotating wheel 17 is rotatably connected to the second baffle 9, and the third rotating wheel 16 is rotatably connected to the third fixed rod 19, ensuring that the second rotating wheel 17 can rotate normally on the second baffle 9 and that the third rotating wheel 16 can rotate normally on the third fixed rod 19.

[0022] In this embodiment, the rotating wheel 16 is rotatably connected to the limiting frame 10 to ensure that the rotating wheel 16 can rotate normally within the limiting frame 10.

[0023] In this embodiment, the first fixing rod 6, the second fixing rod 18, and the third fixing rod 19 are in a straight line to ensure that the suspended load will not sway easily.

[0024] When using the electric pulley block device for lifting heavy objects based on power transmission and distribution line towers in this embodiment, a suitable installation position on the power transmission and distribution line tower should be selected. This position should be able to bear the weight of the device and the heavy object being lifted, and should facilitate subsequent operations. The fixing column 1 should be attached to the installation position on the tower, so that the first ring 2 on one side of the fixing column 1 and the second ring 3 on the other side are located on both sides of the tower. Take four bolts 5 and pass them through both sides of the two rings 1 2 respectively. Then, make one end of the bolt 5 pass through both sides of the corresponding ring 2 3. Tighten the bolt 5 with a wrench. Since the bolt 5 is slidably connected to the ring 1 2 and threadedly connected to the ring 2 3, the fixing column 1 can be firmly fixed to the tower by tightening the bolt 5. Note that you should ensure that the fixing column 1 is installed upright and stable. Rotate the threaded rod 4. Since the threaded rod 4 is threadedly connected to one of the rings 2, the height of the fixed column 1 and the connected parts can be adjusted by rotating the threaded rod 4 to reach a position suitable for lifting operations. After adjustment, keep the position of the threaded rod 4 stable. Confirm that the fixing rod 16 has been fixedly installed on one side of one of the rings 12. Check whether the baffles 17 symmetrically fixed on the fixing rod 16 are secure. Then install the rotating wheel 15 on the fixing rod 16 and between the two baffles 17. Ensure that the rotating wheel 15 can rotate flexibly on the fixing rod 16 and that the baffles 17 can restrict the lateral movement of the rotating wheel 15. Install the second fixing rod 18 directly below the first fixing rod 6. Check whether the baffles 29 symmetrically fixed on the second fixing rod 18 are secure. Install the second rotating wheel 17 on the second fixing rod 18 and between the two baffles 29, ensuring that the second rotating wheel 17 can rotate flexibly on the second fixing rod 18 and that the baffles 29 can restrict its lateral movement. Install a fixed rod 19 directly below the fixed rod 2 18, and fit the limiting frame 10 onto the fixed rod 3 19. Then install the rotating wheel 3 16 on the fixed rod 3 19 and within the limiting frame 10, ensuring that the rotating wheel 3 16 can rotate flexibly within the fixed rod 3 19 and the limiting frame 10. Install the ring buckle 3 20 on the ring buckle 4 21 at the top of the limiting frame 10 and ensure that the connection is firm. Fix one end of the rope 11 to the ring buckle 3 20, and then pass the rope 11 through the rotating wheel 2 17, rotating wheel 3 16 and rotating wheel 1 15 in sequence. Note that the rope 11 should be wound correctly on each rotating wheel to avoid winding errors or loosening. Fix the other end of the rope 11 to the rope take-up roller 13 to ensure that the fixation is reliable. By using the rings 2 and 3 on both sides of the fixed column 1, the entire device is fixed in a suitable position on the power transmission and distribution line tower using bolts 5. Rotating bolts 5 can adjust the tightness of the fixing to ensure that the device is installed stably. Rotating threaded rod 4, since threaded rod 4 is threadedly connected to ring 2, can adjust the height and position of fixed column 1 and related components to adapt to different lifting requirements and tower environment. The entire device is fixed to a suitable position on the power transmission line tower using bolts 5 via rings 2 and 3 on both sides of the fixing column 1. Since bolts 5 are slidably connected to ring 2 and threadedly connected to ring 3, rotating bolts 5 adjusts the tightness of the fixing, ensuring a stable installation. Simultaneously, fixing rod 18 is tightly welded to fixing rod 6 via symmetrically arranged connecting plates 8, further enhancing the overall structural stability. Connect the heavy object to be lifted to the ring 21 at the bottom of the limit frame 10, ensuring a secure connection. At the same time, check the connection of the rope 11. One end of the rope 11 is fixed to the rope take-up roller 13, and the other end passes through the second roller 17, the third roller 16 and the first roller 15 in sequence, and is connected to the ring 20 on the ring 21 at the top of the limit frame 10, ensuring that the rope 11 is correctly wound between each roller and is not loose. The motor 12 is started, and its output shaft drives the rope winding roller 13 to rotate, causing it to begin winding the rope 11. Under the traction of the rope 11, guided and driven by rollers 15, 17, and 16, the limiting frame 10 moves upward on the fixed rod 19, thereby lifting the load. Roller 15 rotates on the fixed rod 6, roller 17 rotates on the fixed rod 18, and roller 16 rotates within the fixed rod 19 and the limiting frame 10, thus limiting the lateral movement of the corresponding rollers. The motor 12 is then reversed, and the rope winding roller 13 releases the rope 11. Under the weight of the load itself, the limiting frame 10 moves the load downward along the fixed rod 19, and the rope 11 unfolds between the rollers, achieving a smooth descent. The motor 12 is then turned off, the rope winding roller 13 stops rotating, the rope 11 stops moving, and the load remains in its current position, completing the lifting or lowering operation.
