When the working position of the traction machine needs to be moved, the traveling wheel 140 can be made to land by adjusting the first leg 112, thereby facilitating the transfer of the traction machine.

[0029] See Figures 1 to 3As shown, the electric control component 210 includes an electrical box 211, a high-voltage distribution unit 212, and at least two inverter controllers 213.

In this embodiment, the traction mechanism 200 includes two rotating components 220 and a linkage component 230. The two traction mechanisms 200 are arranged at intervals along the extension direction of the second section 120 of the main beam. The two traction drums 221 in the two traction mechanisms 200 rotate synchronously through the linkage component 230. Further, in order to make the movement processes of the two traction mechanisms 200 highly synchronous, the linkage component 230 in this embodiment includes two first gear pairs 231 and a second gear pair 232. Among them, the two first gear pairs 231 are respectively connected to the two traction drums 221, and the second gear pair 232 is disposed between the two first gear pairs 231 and meshes with the two first gear pairs 231 respectively, thereby realizing the synchronous movement of the two first gears and the second gear.

[0030] See Figure 4 and Figure 5 As shown, the rotating component 220 in this embodiment further includes a power supply 223 and a speed reducer 224. The power supply 223 is connected to the rotation driver 222, and the speed reducer 224 is disposed between the rotation driver 222 and the traction drum 221. Specifically, the power supply 223 in this embodiment is preferably a storage battery.

[0031] In this embodiment, in order to improve the usage range and flexibility of the wire winding roller 430, the wire winding mechanism 400 in the present application further includes a lifting assembly 410 and a wire arranging assembly 440. Among them, the wire arranging assembly 440 is connected to one end of the first section 110 of the main beam close to the wire winding roller 430. The lifting assembly 410 includes a jacking connecting rod 411, a jacking oil cylinder 412, a hydraulic oil tank 413 and a hydraulic pump 414. The hydraulic pump 414 is connected to the hydraulic oil tank 413. The jacking oil cylinder 412 communicates with the hydraulic oil tank 413, and the jacking connecting rod 411 connected to its working end is rotated through the hydraulic pump 414 to adjust the actual working position of the wire winding roller 430. Further, since the power transmission ropes and cables will be continuously wound on the wire winding roller 430, in order to prevent the power transmission lines from accumulating excessively at the same position on the wire winding roller 430, the present application is also provided with a wire arranging assembly 440, which is connected to the third section 130 of the main beam and is located above the wire winding roller 430 correspondingly. Its specific structure is the conventional structure of the existing wire arranging device, and the present utility model does not make specific limitations on this.

[0032] This embodiment further includes an adjusting mechanism 300. The adjusting mechanism 300 is connected to the third section 130 of the main beam. It includes a limiting assembly 310, a heat management assembly 320 and an instrument box 330. Among them, the limiting assembly 310 is arranged at one end of the third section 130 of the main beam close to the traction mechanism 200. The heat management assembly 320 and the instrument box 330 are respectively arranged at both ends in the width direction of the third section 130 of the main beam. Specifically, the limiting assembly 310 includes a limiting block 311, a jacking block 312 and a jacking oil cylinder. Among them, the limiting block 311 and the jacking block 312 are arranged at an interval in the height direction.

Based on the above structural arrangement, when it is necessary to pause wire winding, such as when replacing the wire winding roller 430, the limiting assembly 310 can squeeze the power transmission lines between the limiting block 311 and the jacking block 312, thereby interrupting the winding and unwinding process of the power transmission ropes and cables, playing a role of temporarily locking and anchoring, and further avoiding the phenomenon that the power transmission ropes and cables are too long and the wire winding mechanism 400 cannot fully accommodate them when it is necessary to change the coil or during a long-term pause of operation, and preventing the power transmission ropes and cables from slackening and slipping on the traction drum 221, resulting in the phenomenon of rope slipping and running away.

[0033] In addition, the thermal management component 320 in this embodiment includes a thermal management unit 323, an expansion tank 321, and a radiator 322. The radiator 322 communicates with the internal and external environments of the thermal management unit 323, and the expansion tank 321 is disposed in contact with the limiting component 310. This ensures the overall structure of this application. In particular, when components such as motors operate for a long time at high power and generate heat, the heat can be quickly discharged to maintain the stability of the system, thereby improving the overall service life of this device. In different embodiments, the number of radiators 322 provided and their specific installation positions can be set according to actual usage requirements, and the present utility model does not make specific limitations in this regard.

[0034] In summary, for the electric tractor for tension stringing of transmission lines described in the present utility model, the transmission line is towed by the towing mechanism 200, and then the transmission ropes and cables are wound by the wire winding mechanism 400, thereby realizing the erection process of the transmission ropes and cables. Among them, the electronic control component 210 can achieve high-precision control of the rotating component 220 and the winding mechanism. The cooperation degree among the various actuating mechanisms is high, and through the assembly mechanism 100, a reasonable layout and stable connection among the various structures can be achieved. Thus, the high-quality towing and automatic winding process of the transmission ropes and cables are realized. Compared with the conventional towing equipment at the present stage, this application has significant advantages such as high automation, high integration, easy operation, pure electric and clean operation, energy conservation and emission reduction, and a wide range of applications, providing new ideas for the towing management of transmission lines.

[0035] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. The obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
