Elevators, as the name suggests, are staircases that use electricity, so electricity must be used. Nowadays, whether it is an elevator used in a house or an elevator used for daily light rail and subway transportation, it is composed of many components. Their internal structure is the core of elevators, so the importance of the internal structure and electricity of elevators does not need to be further discussed by the editor. However, many people often fail to consider some details when choosing an elevator room. Today, let's learn about the internal structure of elevators with the editor? What are the relevant knowledge to pay attention to when choosing an elevator room.

What are the internal structures of elevators

Electric elevators are divided into escalator type and lift type. The internal structure of the two types of elevators is different, as follows:

1. Internal structure of electric escalator:

The escalator consists of a ladder path (a modified plate conveyor) and two side handrails (a modified belt conveyor). Its main components include steps, traction chains and sprockets, guide rail systems, main transmission systems (including electric motors, reduction devices, brakes, and intermediate transmission links), driving spindles, ladder tensioning devices, handrail systems, comb boards, escalator frames, and electrical systems. The steps gradually form a staircase after horizontal movement at the entrance of passengers (to facilitate their climb); The stairs gradually disappear near the entrance, and they move horizontally again. These movements are achieved by the main and auxiliary wheels of the steps walking along different guide rails.

2. Internal structure of elevator:

Elevators are mainly composed of frequency converters, brakes, buffers, safety clamps, speed limiters, introduction devices, automatic switches, transformers, rectifiers, knife switches, transfer switches, contactors, electromagnetic relays, selectors, main control devices, terminal switches, interlocking contacts of doors, braking electromagnets, lighting signal panels, floor lighting signals, signal displays, signal bells, guide rails, elevator shafts, machine rooms, car elevators, platforms, counterweights, etc.

What are the issues to pay attention to when choosing an elevator room

1. Pay attention to asking if the elevator has a backup power supply

The elevator can only operate with electricity. A sudden power outage can cause the running elevator to suddenly stop, which can seriously lead to a sudden drop and affect the safety of personnel inside the elevator. Some residents are unable to take the elevator and need to climb the stairs, which is inconvenient for residents living on high floors with elderly and children at home. Therefore, if buying a new house, it is important to ask if the elevator has a backup power supply; If you are buying a second-hand house, you need to go to the property management and community owners to consult related issues.

2. Pay attention to the size of elevator space

The size of the elevator space is very important. If the space is large, it means it can accommodate more people and things, and no one wants the elevator to be too crowded. Nowadays, there are usually buildings with two elevators, one of which is square and the other is rectangular. A rectangular elevator that can accommodate stretchers. In addition, the convenience of transporting some furniture purchased by individuals to their homes through elevators also needs to be considered.

3. Pay attention to the number of people the elevator can carry

The space is large and can accommodate more people and things, but it is not. Many elevators have a relatively large space, but can only accommodate a small number of people. Usually, there is still a lot of space left in the elevator, but if someone gets on the elevator again, overloading may occur. If the number of elevators is small and there are many residents, but the number of passengers is small, it will be more troublesome to wait for the elevator when commuting.

4. Pay attention to the brand of elevators

Brand determines quality and stability. Domestic pure foreign elevator brands include Otis from the United States, Xunda from Switzerland, Tongli from Finland, Mitsubishi from Japan, ThyssenKrupp from Germany, Hitachi from Japan, Fuji from Japan, Fujita from Japan, Toshiba from Japan, and Hyundai from South Korea. When buying a house, ask about the brand of the elevator and consult relevant information about the elevator brand to verify its quality.

The above is a complete introduction to the internal structure of elevators and the issues that should be paid attention to when choosing an elevator room. Although the emergence of elevators has made our daily travel very convenient, there are still many elevator accidents, so elevator brands and daily maintenance are particularly important. In addition, people's dependence on elevators is so high now, so when buying a house, it is necessary to carefully inquire about the details of elevators, so that our future life is more peaceful and comfortable.
