[0018] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0019] A traction machine for high-altitude cable erection, as Figures 1 - 4As shown in the figure, it includes a support frame 1, a fixed roller 2, a sliding shaft 3, a first spring 4, a sliding roller 5, a connecting shaft 6, a fixed frame 7, a rotating frame 8, a traction wheel set 9, a pin 10, a second spring 11, a connecting frame 15, a driving machine 16 and a gear 17. A fixed roller 2 is rotatably connected to the upper part of the support frame 1. A sliding shaft 3 is slidably connected to the support frame 1. A first spring 4 is connected between the sliding shaft 3 and the support frame 1. A sliding roller 5 is rotatably connected to the sliding shaft 3. A connecting shaft 6 is connected to the lower part of the support frame 1. A fixed frame 7 is rotatably connected to the right part of the connecting shaft 6. A rotating frame 8 is rotatably connected to the left part of the connecting shaft 6. A traction wheel set 9 is provided between the lower parts of the rotating frame 8 and the fixed frame 7. A pin 10 is provided at the lower part of the rotating frame 8. A second spring 11 is provided between the pin 10 and the rotating frame 8. A connecting frame 15 is connected to the top of the support frame 1. A driving machine 16 is connected to the lower part of the connecting frame 15. A gear 17 is connected to the output shaft of the driving machine 16;

[0020] A tooth block is provided at the position of the fixed roller 2 close to the gear 17 for meshing with the gear 17;

[0021] The diameter of the gear 17 is larger than the diameter formed by the tooth blocks, which can improve the driving force of the fixed roller 2;

[0022] The traction wheel set 9 is composed of a fixed shaft and a roller. The fixed shaft is connected to the lower part of the fixed frame 7. The fixed shaft is rotatably connected to the roller. The fixed shaft is clamped with the pin 10;

[0023] A handle is provided at the rear side of the support frame 1 for convenient grasping;

[0024] It further includes a fixed rod 12, a rotating plate 13 and a bolt 14. A fixed rod 12 is rotatably connected inside the rolling wheel. The fixed rod 12 is connected to the support frame 1. A rotating plate 13 is connected to the left side of the fixed rod 12. A bolt 14 is provided at the lower part of the rotating plate 13. The bolt 14 is threadedly connected to the sliding shaft 3.

[0025] When the utility model is in use, first hook the fixed roller 2 on the preset load-bearing steel cable during cable erection. Under the action of the first spring 4, the sliding shaft 3 makes the sliding roller 5 cooperate with the fixed roller 2 to clamp the load-bearing steel cable. After the fixed roller 2 is hooked, turn the bolt 14 into the sliding shaft 3, and use the rotating plate 13 to restrict the downward sliding of the sliding roller 5 to keep it stationary. Then embed the cable to be erected on the traction wheel set 9 and fix the rotating frame 8 with a locking pin. Under the action of the second spring 11, the locking pin is inserted into the fixed shaft in the traction wheel set 9, so that the traction wheel set 9 can only move between the fixed frame 7 and the rotating frame 8. After that, the high-altitude cable erection and traction operation can be carried out. By starting the drive machine 16, the drive machine 16 controls the rotation of the gear 17, drives the fixed roller 2 to rotate, and makes the fixed roller 2 move on the load-bearing steel cable, so that the whole device can move on the load-bearing steel cable. During the movement, the cable is tractioned and erected by the traction wheel set 9 to move along the predetermined path, so that the tractioned cable is parallel to the load-bearing steel cable. Due to the gravity of the cable, it will drive the fixed frame 7 and the rotating frame 8 to rotate on the connecting shaft 6 through the traction wheel set 9, causing a certain degree of inclination, so as to adapt to the gravity of cables with different weights, ensure the smoothness of cable traction, and at the same time maintain a stable connection with the connecting shaft 6 and the support frame 1. When the cable is tractioned to the predetermined position, use the tensioning device to tension the cable to the predetermined tension, and the operator installs and erects the cable. After that, the device can be removed from between the load-bearing steel cable and the cable.

Any person skilled in the art within the technical scope disclosed by the utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claimed rights.
