[0030] like Figure 1 and Figure 2 As shown, a grounding wire reeling and laying vehicle includes a trolley body, which includes a frame 1, a reeling and laying turntable structure 2, and several rotating wheels 3. The frame 1 is provided with a turntable mounting position 4, the reeling and laying turntable structure 2 is installed in the turntable mounting position 4, and several rotating wheels 3 are installed at the bottom of the frame 1.
[0031] The frame 1 includes a push-pull frame 5, a turntable fixing frame 6, and an operating lever mounting frame 7. The push-pull frame 5, the turntable fixing frame 6, and the operating lever mounting frame 7 are integrally formed. The turntable fixing frame 6 is located between the push-pull frame 5 and the operating lever mounting frame 7. The turntable mounting position 4 is located inside the turntable fixing frame 6. The operating lever mounting frame 7 is provided with a plurality of operating lever fixing clips 8.
[0032] It should be noted that this utility model can complete the storage or distribution of grounding wires by shaking the rotating take-up and release turntable structure 2, replacing the current manual storage of grounding wires and coiling of grounding wires on the two supports of the cylinder. This can save the workload of operators in sorting and moving 10kV grounding wire devices, saving time and increasing efficiency.
[0033] like Figure 2 As shown, the push-pull frame 5 is provided with a push-pull grip 9.
[0034] It should be noted that the push-pull grip 9 is ergonomically designed, allowing operators to apply force with one or both hands, reducing physical exertion when moving the trolley. The push-pull frame 5 facilitates pushing the work trolley, improving ease of use. In this embodiment, the surface of the push-pull grip 9 is typically textured with anti-slip material or coated with rubber, ensuring a stable grip even in slippery environments, thus enhancing safety.
[0035] like Figure 2 As shown, the operating rod fixing clip 8 is used to place the grounding operating rod 10. This utility model is provided with multiple operating rod fixing clips 8, which can place multiple grounding operating rods 10 at one time, improving convenience and practicality.
[0036] like Figure 2As shown, the operating rod fixing clamp 8 is an open-shaped pipe clamp, and in this embodiment, the pipe clamp can be made of manganese steel, spring steel plate, or elastic rubber. It has an automatic locking function and can naturally shrink with the size of the grounding operating rod 10, providing a balanced tightening force.
[0037] It should be noted that one end of the operating lever fixing clip 8 can be fixed to the operating lever mounting bracket 7 with bolts or screws, making installation convenient;
[0038] The operating rod fixing clamp 8 is designed as an open-shaped pipe clamp, which allows the grounding operating rod 10 to be directly clamped onto the operating rod fixing clamp 8. It also has a retractable function, so the grounding operating rod 10 can be fixed without additional disassembly or adjustment. It is convenient, quick and easy to use and highly practical.
[0039] like Figure 3 As shown, the operating lever mounting bracket 7 is provided with an operating lever fixing seat 11, the operating lever fixing seat 11 is inclined, and a plurality of operating lever fixing clips 8 are installed on the operating lever fixing seat 11.
[0040] like Figure 3 As shown, the operating lever mounting bracket 7 is also provided with an operating lever support seat 12, and the operating lever support seat 12 is provided with a plurality of operating lever support slots 13.
[0041] It should be noted that the operating rod support groove 13 is used to support the bottom of the grounding operating rod 10, improve the stability of storing the grounding operating rod 10, and further facilitate the taking and picking up of the grounding operating rod 10, making it convenient to use.
[0042] like Figure 4 As shown, the take-up and release turntable structure 2 is provided with a take-up and release winch 14 and a winch mounting base 15. One side of the take-up and release winch 14 is inserted and connected to the winch mounting base 15, and the lower end of the winch mounting base 15 is connected to the turntable fixing frame 6.
[0043] It should be noted that the take-up and release turntable structure 2 in this embodiment is prior art, and is usually composed of a take-up and release winch 14 that carries the pipeline 18, a bearing that supports the turntable, a handle for rocking and rotating the take-up and release winch 14, a limit switch installed on the outer edge of the take-up and release winch 14, etc., wherein the limit switch controls the rotation of the take-up and release winch 14.
[0044] It should be further noted that the limit switch in this embodiment is prior art, and therefore will not be described in detail. (When the limit switch is pressed, the micro switch inside the limit switch is triggered, locking the stop plate through the fixing bolt; when released, the fixing bolt releases the stop plate, allowing the winding winch 14 to rotate freely; the fixing bolt is installed on the adjusting end of the limit switch and is connected to the stop plate through threads; the stop plate is usually a metal sheet or a plastic part; the surface of the winding winch 14 has grooves that match the texture of the stop plate for engaging with the stop plate to achieve mechanical locking.)
[0045] like Figure 4 As shown, a side seat 16 is provided on one side of the winding and unwinding winch 14, and the lower end of the side seat 16 can abut against the winch mounting base 15.

[0049] It should be noted that the grounding clamp 19 is used to firmly connect the grounding wire to the metal casing, conductor or grounding grid of the equipment, ensuring that the current can flow smoothly from the equipment to the ground and form an effective grounding loop; and the clamp's fastening design can ensure the stability of the connection, so that it will not loosen or fall off even when a short-circuit current passes through.
[0050] like Figure 1 and Figure 2 As shown, the rotating bottom wheel 3 is a universal brake wheel.
[0051] It should be noted that the rotating base wheel 3 is designed with omnidirectional brake wheels, which allows the work vehicle to flexibly adjust its direction in narrow spaces and adapt to complex working environments; the wheel foot brake can quickly fix the wheel to prevent the work vehicle from accidentally slipping during operation, ensure the stability of the grounding wire connection, and improve work efficiency and safety.
[0052] like Figures 1 to 4 As shown, the working principle of this utility model is as follows:
[0053] Step 1: Push the work vehicle to a suitable position and press the brake on the rotating bottom wheel 3 to secure the work vehicle.
[0054] Step 2: Loosen the limit switch of the take-up and untake-down turntable structure 2, remove the grounding operating rod 10 on the front, and place it in a suitable position.
[0055] Step 3: Remove the grounding conduit 18 from the side, pull it to a suitable position, and then perform the grounding operation.
[0056] Step 4: After completing the grounding work, simply reverse the previous steps to reel in the wire.
[0057] Step 5: Release the brake on the rotating base wheel 3 to complete the operation.
