Recently, a short video hit the whole network, a woman in Suzhou bought a 9-meter-high loft apartment, but the height of this apartment is 9 meters, although the height is high, but the size of the opening room and the depth are relatively small, so from the bottom up, it is like standing in a well.
Although when buying a house, you know the size and height of the house, but there is no model room, so the understanding is not very intuitive, buying a house is like dismantling a blind box, until the time of receiving the house, I really understand that I bought "a well". The owner of the house said that he liked photography, the house was used as a photography studio, considering the height of the floor and lighting, decided to divide the 9-meter-high space into four floors.
Such a high space, climbing the stairs every day to think about it is also a headache. ay! Why not install an indoor elevator?
If you leave about 1㎡ of space in a corner of the room, install a mini small elevator. This kind of elevator for indoor space requirements are not high, whether it is villas, lofts, bungalows and duplexes can be installed, generally do not need to dig a pit, if the power is cut off, there is a backup battery.
At present, the common household elevators in the market can be divided into three types according to the drive system: screw type, hydraulic type and traction type:
丨 Screw type household elevator
The screw elevator is the driving structure of the nut screw, and the straightforward understanding is to use the screw as the track to raise or decrease the height by rotating relative to the nut. Screw elevator belongs to the machine roomless elevator, in Europe and the United States has been developed for 40 years, the current more dependent on imported brands, the price is generally in 20-30w.
merit:
1. Save space. Screw drive means that the elevator does not have car walls, wire ropes and weight. Therefore, the minimum space requirement is only 900mm*900mm, which is less than 1㎡, just like the space occupied by a shower room.
2, low space requirements. There is no need for a pit, shock absorber or speed limiter, and the choice of installation space can be flexible.
3. High security. The spiral structure is safe and reliable, known as "never falling ladder", and the stability is relatively good.
shortcoming:
1, there is a certain amount of noise. Because the motor is connected to the platform, the mechanical noise of the elevator is relatively close to the human ear.
2, the running speed is relatively slow. The relative operating speed of the screw and nut cannot be too fast, and the elevator running speed can only reach 0.15-0.25 m/s.
丨 Hydraulic type household elevator
Hydraulic elevators belong to more traditional household elevators, but the biggest limitation of hydraulic elevators is oil leakage, and the noise is larger.
1, the civil construction requirements are low, there is no machine room, only need a load-bearing wall, the bottom pit is very shallow.
2, will not suddenly speed out of control, good safety.
3, will not take up too much space.
1. The oil leakage phenomenon is serious.
2, poor comfort, there is a certain amount of motor noise.
丨Traction type household elevator
The traction elevator is to do up and down movements by heavy traction of the car, similar to the principle of lever, the motor only needs a little force. The traction type technology is more mature, the noise is small, and the operation is smooth.
1. Energy saving and environmental protection. The motor power is small, very power-saving, permanent magnet synchronous host does not need to add or replace the oil regularly, there is no oil leakage phenomenon.
2. Smooth operation. There will be no sound of gear friction, the motor is by frequency conversion and pressure change to achieve speed adjustment, the operation is very silky.
3. Price is economical. Compared to screw and hydraulic, the price is lower.
1, the civil construction requirements are relatively high, the height of the top layer is less than 2800mm, it can not be installed, the depth of the foundation pit should be more than 300mm.
2, take up more space. Due to the weight device + rail, it generally occupies 150mm of space than the amount of hydraulic, and the minimum occupation area is 1400mm*1400mm. However, there is a steel belt traction elevator, with steel belt instead of steel wire rope, the minimum occupation area can be reduced to 950mm * 1000mm, while no gear traction, smoothness and silence will be better.
Choosing a suitable elevator is not easy, and it needs to be decided according to various factors:
(1) Location, shaft size, elevator size.
(2) Matching style and style
(3) Elevator function and safety protection measures
(4) The size of the car door
(5) The height of the bottom pit, the top floor, and the car
(6) Main components
(7) Running speed
(8) Manual door security measures.
(9) Budget and manufacturer selection.
Therefore, it is best to customize the meticulous plan of the elevator according to the site situation and budget.
