The trolley support 1 is fixed between the two wheel bodies. A connecting shaft 6 is arranged on the first wheel body 4. The inside of the connecting shaft 6 is hollow, and both ends of the shaft body 3 extend into the connecting shaft 6.

[0041] During transportation, the trolley support 1 is detachable, and the wheel body and the trolley support 1 can be transported separately.

[0042] In this embodiment, both ends of the shaft body 3 of the trolley support 1 extend into the connecting shaft 6 of the traveling wheels 2. The trolley support 1 and the traveling wheels 2 can be fixedly connected. After determining the inclination angle of the trolley support 1, the two are connected to jointly complete the transportation operation.

[0043] As another embodiment of the present utility model, the shaft body 3 can also be replaced by a structure similar to a rotating shaft, and the trolley bracket 1 can rotate arbitrarily.

[0044] As another embodiment of the present utility model, a bearing is provided inside the connecting shaft 6. The trolley bracket 1 and the traveling wheels 2 are rotatably connected. When using this device, rotate the trolley bracket 1 so that the hook 7 on the trolley bracket 1 is hooked on the frequency conversion series resonance withstand voltage device, and then fix the frequency conversion series resonance withstand voltage device on the trolley bracket 1 through the baffle 8. Rotate the trolley bracket 1 to tilt it to an angle convenient for the staff to exert force, and then use the traveling wheels 2 to move it to the target position.

[0045] The trolley bracket 1 is provided with a hook 7 and a baffle 8. The baffle 8 is provided with an arc-shaped contact surface and a connection hole 9. The hook 7 is used to hook up the frequency conversion series resonance withstand voltage device to fix the frequency conversion series resonance withstand voltage device on the trolley bracket 1, and then fix it with the baffle 8. The baffle 8 is provided with an arc-shaped contact surface, so that the outer side of the frequency conversion series resonance withstand voltage device is fully connected to the baffle 8. Then, the frequency conversion series resonance withstand voltage device is reinforced with the connection hole 9 on the baffle 8. It can be fixed by passing a rope through the connection hole 9, or fixed by a hoop and a screw, or directly align the structure on the surface of the frequency conversion series resonance withstand voltage device with the connection hole 9 to fix the frequency conversion series resonance withstand voltage device on the trolley bracket 1.

[0046] A handle 10 is provided at the top of the trolley bracket 1, and the staff holds the handle 10 to transport the frequency conversion series resonance withstand voltage device. Preferably, a wear-resistant layer adapted to the human body temperature or touch can be provided on the outer side of the handle 10, and a convexity conforming to the ergonomics is provided on the surface of the wear-resistant layer to reduce the friction between the human body and the bracket of this device, and at the same time ensure the comfort of the staff during the transportation process.

[0047] The first wheel body 4 includes a tire 11 and a tire bracket 12. The tire bracket 12 includes a fixing plate 13. One end of the fixing plate 13 is fixed to the side of the connecting shaft 6, and the other side of the fixing plate 13 is connected to the tire 11 through a rotating shaft.

The three tires 11 are distributed in an equilateral triangle, and the three fixing plates 13 are equally divided and fixed on the outside of the connecting shaft 6. Through the tire bracket 12, the three tires 11 can be connected into one body, so that this device can climb stairs under the action of the staff's force, reducing the effort of the staff during the transportation of the frequency conversion series resonance withstand voltage device.

[0049] Preferably, an anti-skid pad can be provided on the surface of the tire 11 to increase the friction between the tire 11 and the ground, so that the tire 11 has better grip performance on slippery, muddy or icy roads; at the same time, it can disperse the friction and impact force between the tire 11 and the ground, reduce the wear of the tire 11, and thus extend the service life of the tire 11. In the case of emergency braking, the anti-skid pad can provide stronger braking force, help the vehicle stop faster, and thus shorten the braking distance.

[0053] The rotating tube 19 drives the gear to rotate, the gear is meshed with the adjusting slot 22, and the rotating gear drives the adjusting slot 22 to move, so that the rotating gear changes the length of the adjusting tube 21 extending out of the fixed tube 17.

[0054] The frame 18 is provided with a pin shaft 23, the cross-sectional area of ​​the pin shaft 23 is smaller than the area of ​​the fixing hole, and the gear extends into the fixing hole and is connected to the gear. After adjusting the length of the adjusting tube 21 extending out of the fixing tube 17, the pin shaft 23 is inserted into the fixing hole to limit the rotation of the gear. When adjusting again, the pin shaft 23 can be pulled out to prevent the rotating handle 20 from being accidentally touched and causing the adjustment part to move.

[0055] A moving rod 24 is provided at the end of the regulating tube 21, and a supporting rod 25 and a stabilizing rod 26 are provided on the side of the moving rod 24. The moving rod 24, the supporting rod 25 and the stabilizing rod 26 are fixed in a triangle; a fixing piece 27 is connected to the end of the supporting rod 25. The fixing piece 27 fixes the variable frequency series resonant withstand voltage device, and the moving rod 24, the supporting rod 25 and the stabilizing rod 26 ensure the stability of the fixing.

[0057] On the other side of the fixing member 27, a support plate 30 is provided. The support plate 30 is set to conform to the shape of the variable - frequency series - resonance withstand - voltage device, or a rubber pad 31 is provided on one side of the support plate 30 in close contact with the variable - frequency series - resonance withstand - voltage device, making the fixation more stable.

[0058] Preferably, the vertical rod of the trolley bracket 1 can be telescopic. The telescopic technology on the market is very perfect, so no more elaboration is made here.

[0059] This device can also be used for dry - type transformers, and the use is not restricted.

[0060] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
