Description
Technical Field
[0001] The utility model belongs to the field of elevator safety, and in particular relates to an elevator with improved safety performance. Background Art
[0002] An elevator is a permanent transportation device that serves several specific floors in a building, and its car runs on at least two rows of 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 elevators, where the treads are mounted on crawlers and run continuously, commonly known as escalators or moving walkways. It is a fixed lifting device that serves specified floors. A vertical elevator has a car that runs between at least two rows of vertical or rigid guide rails with an angle of less than 15°. The size and structure of the car are convenient for passengers to enter and exit or load and unload goods. At the end of the 20th century, the elevator used a permanent magnet synchronous traction machine as power, which greatly reduced the area occupied by the machine room, and had the advantages of low energy consumption, energy saving and high efficiency, and fast lifting speed, which greatly promoted the development of real estate towards super-high-rise buildings.
