[0027] like Figures 1 to 7As shown, the utility model provides a grounding wire winding transport vehicle, which includes a frame 1, a panel 2, a front fork 3 and a control handle 4, wherein the panel 2 surrounds the frame 1 and forms a winding bin at the rear side and an electrical bin at the front side in the frame 1, the middle of the front bottom of the frame 1 is fixedly connected to the front fork 3 through a fixing plate 5 extending forward, and driving wheels 6 are provided on the left and right sides of the bottom of the frame 1 and the driving wheels 6 are driven to rotate by a driving motor 7 fixed to the bottom of the frame 1. The lower end of the front fork 3 is connected to a walking wheel 8, and the upper end of the front fork 3 is connected to the lower end of the control handle 4. The upper end of the control handle 4 is provided with a speed adjustment paddle 9 and a brake handle 10. A winding motor 11, a battery pack 12 and an electronic control unit are provided in the electrical compartment. A winding wheel 13 is rotatably connected in the winding compartment, and the winding wheel 13 is transmission-connected to the winding motor 11. The enclosure 2 is provided with a wire inlet and outlet 14 on the upper rear side of the frame 1, and a winding control button group 15 is provided on the outer wall of the enclosure 2.

[0028] It should be noted that the battery pack is preferably a lithium battery with a large energy density, which provides power to the drive motor and the winding motor respectively. The electronic control unit is a technology well known to those skilled in the art and will not be expanded here. Its functions include controlling the start and stop, forward rotation, reverse rotation, speed, etc. of the drive motor and the winding motor. The grounding wire transport vehicle provided by the utility model is equipped with a winding wheel and a mechanical structure suitable for carrying a 750kV grounding wire, which can easily transport the grounding wire from the safety tool room to the work site or the designated location, greatly reducing the user's carrying burden.

[0029] In addition, the control handle Figure 1 In addition to the fixed length shown, it can also be set to an adjustable length or a form that can be folded forward and bent downward to adapt to operators of different heights.

[0030] In one embodiment of the utility model, the two driving wheels 6 are correspondingly connected to the two output shafts of the differential 16 on the rear axle at the bottom of the frame 1 , and the input shaft of the differential 16 is connected to the output end of the driving motor 7 .

[0031] It can be understood that the differential can better solve the problem of different rotation speeds of the two wheels when the transport vehicle turns, ensuring that the transport vehicle turns more smoothly.

[0032] In one embodiment of the utility model, a wire winding bin cover 17 that can be opened and closed is provided on the top of the wire winding bin, and an electrical bin cover 18 that can be opened and closed is provided on the top of the electrical bin.

[0041] Specifically, the grounding wire mobile vehicle provided by the utility model is an electric assisted walking load-bearing vehicle. The vehicle can be equipped with a 600W DC copper core motor with strong output power; the rear wheel dual drive is matched with a differential lock (differential), which makes it have strong obstacle crossing and climbing capabilities; the driving wheels can use solid airless wide tires, which are suitable for all paved areas and most muddy and gravel areas; the braking system uses rear wheel drum brakes, and the braking response is sensitive; the hand-operated speed is adjusted, and the one-button switch can go forward and backward; the front wheels preferably use 10-inch vacuum tires, which are flexible to turn; the body is thickened with steel plates (shrouds), which are more durable, and the body size is reasonably designed to meet the requirements of entering and exiting narrow passages. In terms of winding, the winding mechanism uses an adjustable speed motor, and the winding speed can be freely set within a reasonable range; the same one-button forward and reverse rotation, the winding output is more flexible, the chain transmission can be adjusted, the power transmission is stable, and the reliability is high.
