[0002] An elevator is a permanent transportation device that serves several specific floors in a building, with its car running on at least two rigid rails that are perpendicular to the horizontal plane or inclined at an angle of less than 15° to the plumb line. There are also step-type ones, with the treads mounted on the tracks and running continuously, commonly known as escalators or moving walkways. Fixed lifting equipment that serves specified floors. A vertical lift has a car that runs between at least two rigid rails that are perpendicular or inclined at an angle of less than 15°. The size and structure of the car facilitate the entry and exit of passengers or the loading and unloading of goods. It is customary to use elevators as a general term for vertical transportation tools in buildings regardless of their driving method.

The top telescopic rod 12 is provided with a top electromagnet 13, and the bottom telescopic rod 14 is provided with a bottom electromagnet 15. When the folding top plate 6 and the folding bottom plate 7 are unfolded, the top electromagnet 13 is located in the middle of the top telescopic rod 12 and above the top magnet 27. Preferably, at this time, the top electromagnet 13 is located directly above the top magnet 27, and the bottom electromagnet 15 is located in the middle of the bottom telescopic rod 14 and below the bottom magnet 28. Preferably, at this time, the bottom electromagnet 15 is located directly below the bottom magnet 28.

Specifically, the top middle panel 61 and the extending surfaces of the two top side panels 62 are on the same plane. , the bottom middle plate 71 and the two bottom side panels 72 extending surfaces are on the same plane, firstly, the top electromagnet 13 and the bottom electromagnet 15 generate magnetic force, the magnetic force generated by the top electromagnet 13 is distributed up and down, and the downward magnetic force is the same as the upward magnetic force of the top magnet 27. For example, the magnetism of the top magnet 27 is the N pole facing upward and the S pole facing downward, then the magnetism of the top electromagnet 13 is the S pole facing upward and the N pole facing downward, at this time, a mutually repulsive force is generated between the top electromagnet 13 and the top magnet 27, similarly, the magnetic force generated by the bottom electromagnet 15 is distributed up and down, and the upward magnetic force is the same as the downward magnetic force of the bottom magnet 28. For example, the magnetism of the bottom magnet 28 is the S pole facing upward and the N pole facing downward, then the magnetism of the bottom electromagnet 15 is the S pole facing upward and the N pole facing downward The upper N pole faces the lower S pole. At this time, a mutually repulsive force is generated between the bottom electromagnet 15 and the bottom magnet 28. Subsequently, the top push-pull cylinder 8 and the bottom push-pull cylinder 10 provide the mobile derrick 2 with power to approach the fixed derrick 1, so that the mobile car frame 52 obtains a force to approach the fixed car frame 51.

The folding of the part 5, when the elevator needs to be used, the top electromagnet 13 and the bottom electromagnet 15 do not generate magnetic force. Preferably, whether the top electromagnet 13 and the bottom electromagnet 15 generate magnetic force can be controlled by whether they are powered on or not. The top push-pull cylinder 8 and the bottom push-pull cylinder 10 provide power to drive the mobile derrick 2 away from the fixed derrick 1, and synchronously, the mobile car frame 52 moves away from the fixed car frame 51. As the mobile car frame 52 moves away from the fixed car frame 51, the folding top plate 6 and the folding bottom plate 7 are driven to unfold. As the unfolding proceeds, the top middle plate 61 and the top side panel 62 are in the same plane, the top abutting plate 63 abuts against the top side panel 62, and the bottom middle plate 71 and the bottom side panel 72 are in the same plane.The bottom abutment plate 73 abuts against the bottom side panel 72. Since the top abutment plate 63 is provided, the upward bending of the folding top plate 6 is restricted. Since the bottom abutment plate 73 is provided, the downward bending of the folding bottom plate 7 is restricted. Preferably, the bottom abutment plate 73 is made of a steel plate. Under the action of the bottom abutment plate 73, when a person or an object enters the folding bottom plate 7, the folding bottom plate 7 can smoothly carry the person or the object.

Due to the provision of the bearing plate 26, when the mobile derrick 2 approaches the fixed derrick 1 and the mobile car frame 52 approaches the fixed car frame 51, the bearing plate 26 can be folded to the corresponding pit 3 and the corresponding through opening. The opening 4 is blocked so that the freed space after folding can be utilized. For the present application, protective side panels can be installed on the fixed derrick 1 and the mobile derrick 2 according to the specific situation. The protective side panels can adopt a foldable structure or a telescopic structure. The specific method is selected according to the folding method of the elevator shaft and the specific construction situation of the villa. Similarly, the protective panels installed on the car part 5 and the elevator doors that can be used in the car part 5 can adopt the form of telescopic protective panels and double-leaf elevator doors.
