Description

Publicity display screen for protective elevator

Technical field:

The invention relates to a publicity display screen for a protective elevator, belonging to the technical field of elevator appliances.

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 / s) 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.

At the end of the 20th century, the elevator used permanent magnet synchronous traction machine as power. It greatly reduced the space occupied by the computer room, and has the advantages of low energy consumption, energy saving and high efficiency, and rapid improvement. It greatly boosted the development of real estate to the super high-rise.

The existing elevator propaganda display is inconvenient to use and is easily destroyed, which is complicated to operate and wastes time.
