Technical Field

[0001] The present invention relates to the technical field of magnetic levitation elevators, in particular to a guide shoe structure of a magnetic levitation elevator. Background Art

[0002] At present, the guide shoes used in elevators are mostly roller guide shoe structures. The elevator car moves up and down along the guide rail by sliding between the roller and the guide rail. However, there is a certain amount of friction between the guide shoe and the guide rail. The friction generates vibration and noise during the movement of the guide shoe, which is obvious to passengers in the car. In addition, long-term friction will also cause wear of the guide shoe and the guide rail. Over time, not only will the position of the guide shoe be offset, but it will also affect the working stability of the elevator. In addition, elevator accidents are frequent. It lacks a corresponding active stop function. Due to aging of the equipment, car falls may occur, causing serious personal injuries. Summary of the Invention

[0027] As a preferred solution of this embodiment, an inserting block 210 is installed in the middle of the cover plate 25 close to the guide shoe body 2 , and the inserting block 210 is engaged with the connecting block 22 .

[0028] As a preferred solution of this embodiment: the bottoms of both sides of the guide column 26 are provided with long strip-shaped openings, through which the connection between the connecting block 22 and the guide shoe body can be released and disassembled.

[0029] As a preferred solution of this embodiment: mounting plates are provided at both ends of the guide shoe body 2, and a distance sensor is provided at the bottom of one end of the guide shoe body 2.

[0036] When the connecting plate 24 is not subjected to the pressure of the cam 31, the elastic restoring force of the spring 29 drives the positioning plug 28 to reset, thereby releasing its locking. A protective shell is formed by the mounting shell 23, the connecting plate 24, the cover plate 25 and the mounting plates at both ends of the guide shoe body 2 to protect the guide shoe structure. By folding the cover plate 25, the fixation between the plug 210 and the connecting block 22 is released, thereby facilitating the disassembly and assembly of the connecting block 22, the guide column 26 and the accessories thereon.
