[0002] Ultra-high voltage power transmission has technical advantages such as large power transmission capacity, long distance, high efficiency and low loss, which can greatly improve the power grid's transmission capacity. The construction and lifting of ultra-high voltage and extra-high voltage conductors involves erecting the conductors at a high position between two power lines to ensure safety and protect the conductors. Existing conductor lifting devices typically use a traction method, where one end of the conductor is connected to the power line and the other end is pulled to lay it on the adjacent power line. The existing traction method uses traction devices that only use traction wheels for traction and transportation, which is slow and affects construction efficiency. To address the above issues, we propose a conductor lifting device for ultra-high voltage power construction. Summary of the Invention

[0018] according to Figures 1-10 The present invention relates to a conductor lifting device for ultra-high voltage power construction, comprising a conveyor box 1, wherein the conveyor box 1 is provided with a compression conductor conveying mechanism 2, wherein the compression conductor conveying mechanism 2 is symmetrically arranged in upper and lower sets, and the conductor is conveyed by the upper and lower compression conductor conveying mechanisms 2.

The bevel gear conveyor belt commutator 6 is connected to the secondary extrusion conveying mechanism 5. One end of the auxiliary rotating component 7 is connected to the secondary extrusion conveying mechanism 5, and the other end is connected to the primary conveyor belt mechanism 3. When the primary conveyor belt mechanism 3 is running, the auxiliary rotating component 7 assists the secondary extrusion conveying mechanism 5 in rotating. With the assistance of the bevel gear conveyor belt commutator 6, the rotation direction of the secondary extrusion conveying mechanism 5 is opposite to the rotation direction of the primary conveyor belt mechanism 3. The upper and lower secondary extrusion conveying mechanisms 5 rotate to extrude and convey the wire, thus achieving secondary conveying.

[0019] In a further improvement of the present invention, the primary conveyor belt mechanism 3 includes a conveyor wheel mechanism 8 and a conveyor belt 9. The conveyor wheel mechanism 8 is connected to the conveyor box 1, and the conveyor belt 9 is disposed on the conveyor wheel mechanism 8.

[0020] In a further improvement of the present invention, the secondary extrusion conveying mechanism 5 includes a protrusion 10, a pressure roller shaft 11, and a pressure roller 12.

The collar shaft 18 is coaxially rotatably mounted on the conveying wheel mechanism 8. The ring rack 19 is fixedly connected to the collar shaft 18. The moving gear 20 meshes with the ring rack 19. The movement of the moving gear 20 on the ring rack causes the rotation of the moving gear 20, which in turn causes the pressure roller 12 to rotate.

[0023] In a further improvement of the present invention, the conveyor wheel mechanism 8 is provided with four sets, and the four sets of conveyor wheel mechanisms are respectively located at the four ends of the rectangle. The conveyor wheel mechanism 8 includes a conveyor wheel shaft 21 and a conveyor wheel 22. The conveyor wheel shaft 21 is rotatably mounted in the conveyor box 1 through a bearing, and the conveyor wheel 22 is coaxially fixedly connected to the conveyor wheel shaft 21. The conveyor wheel 22 is pressed against the conveyor belt 9. The conveyor wheel 22 is provided with anti-slip texture to prevent slippage between the conveyor wheel 22 and the conveyor belt 9; The collar shaft 18 is coaxially rotatably sleeved on the conveyor wheel shaft 21, and the conveyor wheel shaft 21 supports the collar shaft 18, thereby supporting the annular rack 19.

[0024] In a further improvement of the present invention, the conveyor box 1 is provided with a drive mechanism 23. The drive mechanism 23 includes a drive motor 24, a motor shaft 25, and a pulley mechanism 26. The drive motor 24 is fixedly connected inside the conveyor box 1, and the motor shaft 25 is fixedly connected to the output end of the drive motor 24. The pulley mechanism 26 has two sets, which are respectively connected to two extrusion wire conveying mechanisms 2 and the motor shaft 25.

In one set of the pulley mechanism 26, the two pulleys 27 are coaxially fixedly connected to the motor shaft 25 and one of the conveyor wheel shafts 21, respectively. In the other set of the pulley mechanism 26, the two pulleys 27 are coaxially fixedly connected to the two conveyor wheel shafts 21 of the two extrusion wire conveying mechanisms 2, respectively. When the drive motor 24 is started, it drives the corresponding extrusion wire conveying mechanism 2 to run through the corresponding pulley mechanism 26. The other set of pulley mechanisms 26 drives the other set of extrusion wire conveying mechanisms 2 to run.

[0025] In a further improvement of the present invention, the front and rear ends of the conveyor box 1 are respectively provided with an inlet and an outlet, and a guide mechanism 32 is provided at the inlet to prevent the wire from rubbing against the conveyor box 1.

[0026] The guiding mechanism 32 has two sets, upper and lower. The guiding mechanism 32 includes a connecting plate 29, a guide wheel shaft 30, and a guide wheel 31. The connecting plate 29 is fixed to the conveyor box 1. The guide wheel shaft 30 is connected to the connecting plate 29. The guide wheel 31 is coaxially rotated and sleeved on the guide wheel shaft 30. The wire passes between the upper and lower guide wheels 31.

[0027] The principle of this invention: When in use, the wire passes through the inlet and between the upper and lower pressure rollers 12, and comes out from the outlet. The drive motor 24 starts, which drives the motor shaft 25 to rotate, which in turn drives the pulley 27 on the motor shaft 25 to rotate. Through the connecting belt 28, it drives another pulley 27 to rotate, which drives the conveyor wheel shaft 21 to rotate, which drives the conveyor wheel 22 to rotate, which drives the conveyor belt 9 to perform a circular motion. Through another pulley mechanism 26, it drives the upper conveyor belt 9 to perform a circular motion. When the upper and lower conveyor belts 9 are running, they drive the two opposing secondary extrusion conveyor mechanisms 4 to move, and perform primary conveying of the wire (the conveyor belt 9 drives the protrusion 10 to move, thereby driving the pressure roller shaft 11 to move, and then driving the pressure roller 12 to move, and the extruded wire is conveyed by the movement of the upper and lower pressure rollers 12). When the secondary extrusion conveyor mechanism 4 moves, its internal bevel gear shaft 17 moves, driving the moving gear 20 to move. With the assistance of the ring rack 19, the moving gear 20 rotates, the bevel gear shaft 17 rotates, driving the bevel gear three 16 to rotate, driving the bevel gear two 16 to rotate, driving the bevel gear one 13 to rotate, driving the pressure roller shaft 11 to rotate, driving the pressure roller 12 to rotate. The two pressure rollers 12 rotate, driving the guide wire to move forward for secondary conveying. The rotation direction of the pressure roller 12 is opposite to the rotation direction of the conveyor belt 9. Therefore, secondary conveying can be carried out on the basis of primary conveying.

[0028] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
