[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This magnetic eddy current steering device provides power to the device through a hub motor on the support frame, allowing the device to move back and forth under passenger control. Through the elastic force of the top spring, the slider pushes one end of the connecting rod, and the other end of the connecting rod pushes the rotating rod. The rotating rod pushes the guide wheel to squeeze the channel steel, giving the device stronger grip and allowing it to climb a certain slope under the power of the hub motor. The limiting wheel and baffle on the mounting block prevent the device from rotating and tipping over in the pipe. When encountering a turn, the guide wheels on both sides are squeezed by the channel steel. Through the elastic force of the spring and the linkage of the connecting rod and the rotating rod, the device is flexibly guided, allowing it to turn smoothly. When braking is required, the disc brake assembly can be controlled to clamp the baffle and brake the device. Through the above structure, the device can smoothly pass through curves, has a certain climbing ability, and has a good braking effect, greatly improving the usability of the pipe trolley.
