[0002] At present, traction machines are often used in the process of long-distance line stringing, and traction machines are generally used in conjunction with tension machines. When releasing the line, first place the traction rope drum on the tail frame of the traction machine, take out one end of the traction rope, and pass it around the two traction wheels at the same time, and then drive the two traction wheels to rotate through the drive motor to release the line; when it is necessary to reel in the line, the two traction wheels can be driven to reverse through the drive motor, and the reeling motor can be used to drive the traction rope drum to rotate, and the traction rope can be wound around the traction rope drum.

[0003] When the traction rope is wound on the traction wheel, the rope can be fed in from the left end of the traction wheel and out from the right end, or the rope can be fed in from the right end of the traction wheel and out from the left end. However, no matter which winding method is used, the guide devices for guiding the traction rope on the traction wheel in the existing traction machine are mostly fixed, which is inconvenient in actual use and cannot be adjusted according to different winding methods. In addition, when winding the line, there is also a lack of a device for guiding the traction rope drum, resulting in the traction rope wound on the traction rope drum being messy and inconvenient for next use.

[0004] Therefore, improvements are urgently needed. Utility Model Content

[0006] In the first aspect, an embodiment of the utility model provides a traction mechanism, including a frame, an electric control box, a first guide assembly and a second guide assembly. Two traction wheels arranged side by side in front and back and a drive motor for driving the two traction wheels to rotate are arranged in the middle of the frame. A brake is arranged on the traction wheel. The drive motor is connected to the wheel axles of the two traction wheels through a reducer. The drive motor is powered by a lithium battery pack and can also be connected to the mains for power supply, or hydrogen energy can be used as a power source, which is pollution-free and highly efficient. A traction machine tail frame is arranged at the rear end of the frame. The traction machine tail frame is used to place a traction rope drum. The electric control box is fixedly arranged on the frame and is located between the traction machine tail frame and the traction wheel.

[0008] The second guide assembly is located between the electric control box and the tail frame of the traction machine. The second guide assembly includes two fixed plates, a guide rod, a lead screw, a sliding block, a servo motor and a second guide roller group. The two fixed plates are fixed at the left and right ends of the rear side of the box body of the electric control box. The guide rod is fixed between the two fixed plates. The lead screw is rotatably connected between the two fixed plates and is located above the guide rod.

The servo motor is fixedly arranged on the outer side of the fixed plate, and the output shaft of the servo motor is transmission-connected to the lead screw. The second guide roller group includes a second transverse guide roller and two second longitudinal guide rollers arranged on the sliding block, and the two second longitudinal guide rollers are located on the front and rear sides of the second transverse guide roller and are staggered left and right.

[0009] Neither the first guide assembly nor the second guide assembly will affect the normal opening and closing of the cover of the electric control box.

[0010] Optionally, each traction wheel is provided with a plurality of grooves.

[0011] In particular, the groove facilitates winding of the traction rope.

[0012] Optionally, a cooling fan is provided at the front end of the rack, and an air outlet of the cooling fan faces the driving motor.
