And without conflict, the embodiments in this application and the features in the embodiments may be combined with each other.

[0045] In the description of the embodiments of this application, the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of this application is usually placed during use, or the orientation or positional relationship commonly understood by those skilled in the art.

[0046] High-voltage transmission lines are generally composed of four or six cables in a bundle. Each bundle needs to be installed with insulating brackets at a certain distance. Therefore, workers need to walk long distances on high-voltage transmission lines. Among them, the cables located at the top of the high-voltage transmission lines are called upper cables, and the cables located at the bottom are called lower cables. The process of workers walking on high-voltage transmission lines is: the workers hold the upper cables with both hands and stand on the lower cables with both feet. However, walking at high altitude consumes a lot of physical energy for workers, increases working time, and reduces the progress of the project.

[0047] To solve the above problems, see Figure 1 , Figure 2 , Figure 3 , Figure 4 An electric pulley vehicle for aerial cable operations provided in an embodiment of the present application includes a vertical pole 11, a vertical pole safety ring 13 is provided at the upper end of the vertical pole 11, a supporting base plate 6 is provided at the lower end of the vertical pole 11, two pulleys 19 for supporting on a lower cable 18 are provided below the supporting base plate 6, and an electric driving mechanism for driving the two pulleys 19 to roll on the lower cable 18 is also provided on the supporting base plate 6.

[0048] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , the vertical pole 11 can be made of steel pipe; for example, the vertical pole 11 can be made of φ32×4 stainless steel pipe. The vertical pole safety ring 13 is a ring structure, which is welded to the upper end of the vertical pole 11. The vertical pole 11 is used for workers to hold when in use, and the vertical pole safety ring 13 is used to connect with the safety ring on the upper cable through a safety rope to prevent the electric pulley car from accidentally falling and improve safety. The supporting base plate 6 can be made of steel plate; for example, the supporting base plate 6 can be made of 3mm thick stainless steel plate. The supporting base plate 6 is welded to the lower end of the vertical pole 11 for workers to stand on their feet to bear the weight of the workers. The two pulleys 19 are arranged at intervals and are rotatably installed below the supporting base plate 6. The two pulleys 19 are used to support the lower cable 18 at the same time, not only to bear the load from the supporting base plate 6, but also to make the pulley 19 roll on the lower cable 18. Since there is a groove on the outer peripheral surface of the pulley 19, when the pulley 19 is supported on the lower cable 18, the lower cable 18 is located in the groove, which can prevent the pulley 19 from slipping off the lower cable 18 during rolling, thereby improving safety. Exemplarily, the pulley 19 can be made of ABS engineering plastic material. The pulley 19 made of ABS engineering plastic can increase the friction between the pulley 19 and the lower cable 18, prevent the pulley 19 from slipping on the lower cable 18, and ensure that the pulley 19 can stably transmit force under the action of vertical load and maintain the force transmission efficiency. The electric drive mechanism is installed on the supporting base plate 6 to provide power to drive the two pulleys 19 to roll on the lower cable 18.

[0049] The aerial cable operation provided in the embodiment of the present application uses an electric pulley to drive workers to move on the aerial cable, and then quickly move the workers to the working position for installation work; the specific installation operation process is:

[0050] First, place two pulleys 19 on the lower cable 18, connect the pole safety ring 13 with the safety ring on the upper cable through the safety rope, and connect the safety rope on the worker with the safety ring on the upper cable; then, the worker holds the pole 11 with one hand and the safety ring on the upper cable with the other hand, and stands on the support base 6 with both feet; wherein the safety ring can move on the upper cable; then, start the electric drive mechanism, which drives the pulley 19 to roll on the lower cable 18 to drive the worker to move on the high-altitude cable; when the worker moves to the working position, turn off the electric drive mechanism, the worker leaves the electric pulley cart and stands on the lower cable 18 to install the insulating bracket. When the insulating bracket is installed, the worker is moved to the next working position by the electric pulley cart.

[0051] The aerial cable operation provided in the embodiment of the present application uses an electric pulley, which reduces the need for workers to walk long distances on the aerial cables compared to the prior art, thereby reducing the physical exertion of the workers, shortening the working hours, and improving the progress of the project.
