[0023] As shown in the attached Figure 1 to the attached Figure 4 figures:

[0024] The utility model provides a cable safety traction device for electric power line construction, including a base 1. On both sides of the top end of the base 1, fixing frames 2 are installed. A positioning mechanism 3 is arranged inside the fixing frames 2. Between the two groups of fixing frames 2 at the top end of the base 1, a first tire group 4 is connected. One side of the first tire group 4 is connected with a second tire group 5. One ends of the first tire group 4 and the second tire group 5 both extend into the base 1 and are connected with a transmission box 6. On one side of the top end of the base 1, two waist-shaped grooves are symmetrically opened. The diameter of the groove opening of the waist-shaped groove is the same as the diameter of the fixed shaft at the bottom end of the first tire group 4. On one side of the transmission box 6 at the bottom end of the first tire group 4, a threaded column 7 is rotatably connected. A threaded hole is opened on one side of the base 1. One end of the threaded column 7 passes through the threaded hole and extends to the outside of the base 1 and is fixedly connected with a handle 8.

[0025] Wherein, on both sides of the threaded column 7, the transmission box 6 is symmetrically connected with optical shafts 9. A through hole with the same diameter as the optical shaft 9 is opened on one side of the base 1. The through hole and the threaded hole are on the same side. One end of the optical shaft 9 extends to the outside of the through hole and is fixedly connected with a retaining ring 10, which is convenient for guiding the movement of the transmission box 6 and preventing the threaded column 7 from driving the transmission box 6 to move and shift, affecting the use.

[0026] Wherein, one ends of the first tire group 4 and the second tire group 5 both extend into the transmission box 6 and are fixedly installed with first synchronous pulleys. The two first synchronous pulleys are connected by a first synchronous belt 11. Inside the transmission box 6, driving motors 12 are fixedly connected. The driving motors 12 are in transmission connection with one of the first synchronous pulleys, which is convenient for providing power for the first tire group 4 and the second tire group 5, enabling the first tire group 4 and the second tire group 5 to clamp the cable and move, and improving the use convenience of the device.

[0027] Wherein, the positioning mechanism 3 includes a bidirectional screw 301 vertically connected to both ends of the bottom of the fixing frame 2. The bottom end of the bidirectional screw 301 is rotatably connected with the base 1. On the outer surfaces of the two bidirectional screws 301, two connecting blocks 302 are threadedly connected. Between two adjacent connecting blocks 302 on the same horizontal plane, a positioning roller 303 is rotatably connected. The two positioning rollers 303 can limit the moving track of the cable entering, so that the cable entering the interior remains horizontal, thus achieving a good positioning effect.

[0028] Wherein, one ends of the two bidirectional screws 301 both extend into the fixing frame 2 and are fixedly installed with second synchronous pulleys. The two second synchronous pulleys are connected by a second synchronous belt 304. The top end of the fixing frame 2 is rotatably connected with a turning handle 305. The turning handle 305 is coaxially connected with one of the second synchronous pulleys. The turning handle 305 drives the two bidirectional screws 301 to rotate synchronously through the second synchronous belt 304, so that the bidirectional screws 301 synchronously adjust the distance between the two positioning rollers 303 to position cables with different diameters.

[0029] Among them, a positioning groove distributed in a ring shape is formed at the top end of the fixing frame 2. A positioning pin 306 is inserted on the surface of the rotary handle 305. The bottom end of the positioning pin 306 penetrates through the rotary handle 305 and is inserted into the adjacent positioning groove. The positioning groove can firmly fix the rotary handle 305 on the surface of the fixing frame 2 through the positioning pin 306 to prevent the bidirectional screw 301 from loosening, thereby achieving a good positioning effect.

[0030] Among them, both sides of the base 1 are fixedly connected with support frames 13 through bolts, and the support frames 13 are U-shaped, which is convenient for providing stable support for the base 1, and the structure is simple.

[0031] The working principle of this embodiment: When the traction device is in use, first place the device on the construction site through the support frame 13 according to needs, and then rotate the threaded column 7 through the handle 8 and adjust the distance between the first tire group 4 and the second tire group 5 according to the size of the cable, so that the cable can be clamped by the first tire group 4 and the second tire group 5; then rotate the rotary handle 305, and the rotary handle 305 drives the two bidirectional screws 301 to rotate through the second synchronous belt 304, so that the bidirectional screws 301 adjust the distance between the two positioning rollers 303 through rotation to position cables with different diameters. After adjustment, firmly fix the rotary handle 305 in the positioning groove at the top end of the fixing frame 2 through the positioning pin 306 to achieve a good positioning effect. Finally, turn on the drive motor 12, and the drive motor 12 drives the first tire group 4 and the second tire group 5 to rotate to carry out the traction work of the cable.
