What is an elevator

1. Definition of elevator

An elevator is a permanent transport that serves a number of specific floors within a building and whose car is running on at least two rows of rigid orbits perpendicular to the horizo​​ntal plane or inclined less than 15 ° from the plumb line. 

Habitually no matter how the driving method, the elevator as a general term for vertical transport within the building also has a step-type, step on the track mounted on the track, commonly known as escalators or moving sidewalks. Served on the provisions of the fixed floor lift equipment. The vertical lift has a car running between at least two vertical rows or rigid rails with an inclination of less than 15 °. Car size and structure form for passengers to access or loading and unloading of goods.

Habitually no matter how the driving method, the elevator as a general term for vertical transport within the building.

According to the speed can be divided into low-speed elevators (4 m / s below), fast elevators 4 to 12 m / s) and high-speed elevators (12 m / s or more). Hydraulic elevators began to appear in the mid-19th century and are still being used in low-rise buildings.

In 1852, EG Otis in the United States developed a rope hoist safety lifts.

80s, the drive has further improvements, such as the motor through the worm drive belt winding drum, using the balance weight and so on.

The late 19th century, the friction wheel drive, greatly increasing the elevator lift height.

At the end of the 20th century, the elevator used permanent magnet synchronous traction machine as power. Greatly reducing the area of​​ ​​the engine room, and has the advantages of low energy consumption, energy saving and efficiency, speed up, etc., greatly boosting the real estate to the direction of the super-high-rise.

2. The type of elevator

The type of elevator

The types of elevators include manned (cargo) elevators , escalators, moving walkways and the like.

According to their use, the elevator can be divided into passenger elevator , freight elevator, hospital bed elevator , residential elevator, debris elevator, sightseeing elevator and marine elevator. According to the operating speed can be divided into super-high-speed elevators (speed greater than 6m / s), high-speed elevators (speed of 2.5 ~ 6m / s), medium-speed elevators (speed greater than 1m / s and less than or equal to 2m / s) (Speed of 1m / s or less ).

 

3. The composition of the elevator

The following briefly introduces the important components of the elevator:

1. Space

Room part, hoistway and pit part, car part, landing part.

2. System

Traction system: The main function of the traction system is the output and transmission of power, so that the elevator operation. Traction system consists of traction machine, traction rope, guide wheel, anti-rope wheel composition.

Guiding system: The main function of the guidance system is to limit the freedom of movement of the car and the counterweight so that the car and the counterweight can only move up and down along the guide rail. The guide system is mainly composed of guide rails , guide shoes and guide rails.

Car: The car is an elevator component that carries passengers and goods and is the working part of the elevator. The car consists of a car frame and a car body.

Door system: The main function of the door system is to seal the landing entrance and the car entrance. Door system consists of car door, landing door, door opener, door lock device.

Weight Balance System: The main function of the system is to balance the weight of the car. During the work of the elevator, the weight difference between the car and the counterweight can be kept within the limit, and the traction drive of the elevator is normal. System mainly by the weight and weight compensation device.

Electric drive system: Electric drive system is to provide power, the implementation of elevator speed control. Electric traction system consists of traction motor, power supply system, speed feedback device, motor speed control device and so on.

Electrical Control System: The main function of the electrical control system is to operate and control the operation of the elevator. Electrical control system mainly by the control device, position display device, control panel (cabinet), leveling device, layering device and other components .

Security system: to ensure the safe use of elevators to prevent any accidents that endanger personal safety. The elevator speed limiter, safety gear, rope clamp, buffer, safety touch plate, landing door locks, elevator safety windows, elevator overload limit device, limit switch device.

3. Application Technology

1. All-digital identification of passenger technology (all passengers before entering the elevator to identify, including eye recognition, fingerprinting)

2. Digital intelligent safety control technology (through the passenger identification system or IC card and digital monitoring equipment, refused to enter by outsiders)

3. The fourth generation of machine roomless elevator technology (the host must be separated from the guide rail and the car, there is no resonance resonance, the speed can reach 2.0M / S or more, the maximum can be used in 30 or more .)

4. Two-way safety technology (two-way safety gear, two-way speed limiter must be used in Europe, China is being widely used)

5. Rapid installation technology (to change the past, the elevator installation method, to quickly assemble)

6. Energy-saving technologies (using energy-saving technologies to make the elevator more energy)

7. Digital monitoring technology (full use of computer monitoring and control of the elevator)

8. Wireless remote control and alarming device (When elevator fails, the elevator can send fault message to the cellphone via wireless device and send simple signal to the elevator through cellphone.)
