Description

Damper mechanism for elevator

Technical field

The invention relates to a cushion mechanism for an elevator, belonging to the technical field of elevators.

Background technique

The elevator is an electric motor-powered vertical lift with a box-shaped pod for multi-storey buildings to take passengers or carry cargo. There is also a step type, and the tread plate is continuously operated on the crawler belt, commonly known as an escalator or a moving walkway. A fixed lifting device that serves the specified floor. The vertical elevator has a car that runs between at least two columns of rigid rails that are perpendicular or have an angle of inclination of less than 15°. The car is sized and structured to allow passengers to access or load cargo. It is customary to use the elevator as a general term for vertical transportation vehicles in buildings, regardless of the driving method. According to the speed, it can be divided into low speed elevator (less than 1 m / sec), fast elevator (1-2 m / sec) and high speed elevator (2 m / sec or more). Hydraulic elevators began to appear in the mid-19th century and are still used in low-rise buildings. In 1852, E.G. Otis of the United States developed a safety lift for wire rope lifting. In the 1980s, the drive unit was further improved, such as the motor driven by a worm drive to wind the reel, using a counterweight. At the end of the 19th century, friction wheel transmission was adopted, which greatly increased the lifting height of the elevator.
