[0058] The framework beam 41 can be disassembled into multiple by the assembly and disassembly part 44 to facilitate storage; when disassembled, the positioning connection channel 442 and the connection beam 443 are pulled apart in opposite directions to separate, and at this time, the positioning tooth rim 441 is separated to achieve disassembly; when needed, the positioning tooth rim 441, the positioning connection channel 442, and the connection beam 443 are positioned, and then pushed towards each other to complete the connection, so that the multiple framework beams 41 are combined into a whole.

[0060] The controller 33 is used to supply power to the driving winding 31, and the driving conductor 32 generates a magnetic force repelling the suspension magnet 2 after being supplied with power. The controller 33 controls the power supply of the driving winding 31 to change the size of the magnetic force, so that the suspension distance of the shoe roller 100 relative to the magnetic suspension device 3 changes. When the power and the magnetic force increase, the suspension distance of the shoe roller 100 relative to the magnetic suspension device 3 increases, and vice versa.

[0061] As an optional embodiment, the driving conductor 32 is provided with a groove matched with the shape of the shaft head. When the driving winding 31 is supplied with power to generate a magnetic force repelling the suspension magnet 2, the gap for the shoe sleeve 200 to pass through is formed between the groove and the shaft head.
