[0002] In recent years, as the country advocates energy conservation and the development of clean energy, new energy sources such as solar power generation and wind power generation have become extremely important. AC and DC (extra-high and ultra-high) high voltage transmission lines are carriers for electric energy transmission. The construction of AC and DC (extra-high and ultra-high) high voltage transmission lines needs to pass through many high mountains and uninhabited areas. In order to protect the ecological environment and restore the environment and water conservation after construction, it is extremely difficult to achieve absolute flat ground in the tower construction area. During the tower assembly construction, there are often a large number of steel wire ropes for lifting tower materials on the ground, which are scratched, worn, scraped, and rubbed against the ground. Especially in the construction of mountainous areas and tower base construction areas with complex terrain, in order to effectively protect the steel wire rope from scratching, grinding, scraping, and rubbing, improve the safety and reliability of the work process, eliminate the safety hazards such as lifting injuries and object strikes during work, and prevent vicious safety accidents, it is a problem that needs to be solved urgently in reality.

[0005] Furthermore, the rotating roller and its arc-shaped retaining plate are both made by machining carbon steel pipes, the diameter of the rotating roller is between Ф108 and Ф219 mm, and the diameter of the arc-shaped retaining plate is between Ф160 and Ф288 mm.

[0006] Furthermore, the fixed height of the bearing support is 250 mm.

[0007] Furthermore, the ground roller pulley frame is formed by welding galvanized square tubes, and the size of the square tube profile is 80x80x6mm;

[0008] Furthermore, the length of the frame ground anchor rod is between 600 mm and 1500 mm.

[0013] During the installation of the ground-mounted holding pole during the assembly construction of the AC / DC (extra-high and ultra-high) high-voltage transmission tower, the holding pole lifts the tower material components through the wire rope and pulley block. The lifting power comes from the winch fixed on the ground. After the holding pole and the winch are installed in place, the direction of the wire rope for traction and power transmission can be determined. In the case of special landforms with many high mountains and uninhabited areas, there are scratches, grinding, scraping and rubbing between the wire rope and the undulating ground. Therefore, the patented equipment of the utility model is installed at the position where there are scratches, grinding, scraping and rubbing between the wire rope and the raised ground.

[0014] Reference Figure 1 and Figure 2 As shown, first assemble the rotating roller 3 and the bearing support 4 with the ground roller pulley frame 1 and fasten them with bolts 2. If multiple ground roller pulleys need to be connected in parallel, repeat the above steps and connect them in parallel through bolts 2. Place the roller pulley in the installation position, firmly fix the ground roller pulley frame 1 to the ground with the frame ground anchor rod 5, place the traction wire rope on the roller pulley, and finally check whether the roller pulley rotates smoothly and without jamming before use. If necessary, add lubricating oil through the oil filling cup 6 to ensure safe operation.

[0016] The frame of the ground roller pulley rack is formed by welding galvanized square tubes, and the square tube profile is 80x80x6mm; the length of the frame ground anchor rod 5 of the fixed frame is between 600mm and 1500mm, and the ground anchor length is determined according to the on-site geological conditions, and the ground anchor length specification is determined by calculation in the construction plan; multiple ground roller pulley racks 1 can be connected by bolts 2, and multiple ground roller pulleys are expanded and connected in parallel, so as to ensure the expansion and use of multiple parallel traction wire ropes in width; the ground roller pulley rack 1 is rigidly hinged into one, which improves the stability, safety and reliability of the construction process and eliminates the potential safety hazards in the construction process; in addition to being used in UHV transmission line projects, ground roller pulleys can also be used in other rope-supporting work scenes where multiple parallel wire ropes are traction-moved on the ground to prevent the wire ropes from being scratched, ground, scraped, rubbed, etc., improve the safety and reliability of the work process, eliminate the potential safety hazards such as lifting injuries and object strikes during work, and prevent vicious safety accidents, especially in the construction of mountainous and tower base construction areas with complex terrain, which has considerable promotion significance.
