Spiral over-and-under type passenger elevator

Technical Field

The utility model relates to a manned elevator technical field, more specifically relate to a spiral over-and-under type manned elevator.

Background

An elevator is a permanent transport device serving a number of specific floors in a building, the cars of which travel in at least two rigid tracks perpendicular to the horizontal or inclined at an angle of less than 15 ° to the vertical. There are also steps, where the tread plates are mounted on a track for continuous operation, commonly known as escalators or moving walkways. A fixed elevator apparatus serving a predetermined floor. The vertical lift elevator has a car that runs between at least two vertical rows of rigid guide rails or guide rails with an angle of inclination of less than 15 °. The size and the structural form of the car are convenient for passengers to access or load and unload goods. It is customary to use elevators as a generic term for vertical transport means in buildings, irrespective of their drive mode. According to the speed, the elevator can be divided into a low-speed elevator (below 4 m/s), a high-speed elevator (4-12 m/s) and a high-speed elevator (above 12 m/s). The hydraulic elevator begins to appear in the middle of the 19 th century and is still applied to low-rise buildings until now. In 1852, e.g. austs in the united states developed a safety hoist for wire rope hoisting. In the 80 s, further improvements were made to the drive means, such as motors driving the winding drum via a worm drive, the use of counterweights, etc. At the end of the 19 th century, friction wheel transmission is adopted, and the lifting height of the elevator is greatly increased.

The elevator in the prior art adopts a permanent magnet synchronous traction machine as power. The machine room occupation is greatly reduced, the energy consumption is low, the energy is saved, the efficiency is high, the lifting speed is high, and the like, and the development of real estate to the direction of an ultra-high layer is greatly promoted.

After entering the elderly society, the installation of elevators next to older buildings and the subsequent cost of everyday expenses have hindered this from developing for a variety of reasons.

Therefore, it is necessary to develop a safe, simple, low-cost, easy-to-operate and convenient-to-maintain manned elevator.
