The main structure of the villa elevator: there are host control cabinet, traction machine, speed limiter, brake and traction wheel in the machine room. The people in the middle are called lift cars. There are landing doors on each floor. There are counterweights outside the lift car and inside the hoistway, which are connected by wire ropes. The counterweight goes up and the lift car goes down, and the counterweight goes down and the lift car goes up.

别墅电梯会急速下坠吗？

Will the villa elevator fall rapidly?

“电梯下坠”是生活中经常遇到的一种故障，实际上电梯并不是真的下坠了。一般有两种情况：

"Elevator falling" is a kind of fault often encountered in life. In fact, the elevator is not really falling. There are two general situations:

1、电梯运行过程中急停

1. Emergency stop during elevator operation

一般这种都是因为运行过程中回路或者门锁回路断开，造成电梯停止，乘客会感觉腿发麻，其实是电梯紧急停止造成的

Generally, this is caused by the disconnection of the safety circuit or the door lock circuit during operation, which causes the elevator to stop, and the passengers will feel numb in their legs. In fact, it is caused by the emergency stop of the elevator

2、电梯运行过程中出现故障并自动回到基站复位

2. If the elevator fails during operation, it will automatically return to the base station for resetting

这个时候把每一个楼层按一遍其实也没有太多作用，有一些电梯会就近平层并开门，而大多数的电梯都是回到基站复位的，这个时候一般是按不了楼层的。

It doesn't really help to click each floor once at this time. Some elevators will level and open the door nearby, while most elevators return to the base station to reset. Generally, you can't click the floor at this time.

再来说一下被大部分人误解的“电梯掉下来”，这种情况发生的概率和买彩票中500万的概率差不多。

Let's talk about the "elevator falls" misunderstood by most people. The probability of this situation is almost the same as the probability of 5 million in the lottery.

别墅电梯轿厢是由钢丝绳牵引的，载重量越大钢丝绳根数越多，对于一般别墅电梯来说，少是3根钢丝绳，每根钢丝绳大约有10股小的钢股，每根钢股又有10根钢丝，钢丝绳只要断一股就会更换整条，所以钢丝绳全部断掉的概率真的是几乎没有。

The lift car of villa elevator is pulled by steel wire ropes. The greater the load, the more steel wire ropes. For ordinary villa elevators, there are only 3 steel wire ropes. Each steel wire rope has about 10 small steel strands, and each steel strand has 10 steel wires. As long as one strand of steel wire rope is broken, the whole steel wire rope will be replaced. Therefore, the probability of all steel wire ropes being broken is almost zero.

理论上一根钢丝绳就能拉起整个轿厢的重量，不过为了保险和避免轿厢摇摇晃晃，目前新安装的别墅电梯基本都是五根以上。绳头废弃了巴氏合金法，普遍用楔形自锁了

Theoretically, one steel wire rope can lift the weight of the whole car. However, in order to ensure and avoid the car from swaying, the newly installed villa elevators are basically more than five. Babbitt alloy method is abandoned for rope head, and wedge self-locking is generally used

而新的别墅电梯一般是使用钢带的，就像是把钢丝绳展开，再在外面包上橡胶层，这种钢带就算是发生火灾把外面的橡胶层全部烧掉都是能使用的。钢带是2000年开发出来的，技术已经是非常成熟了。

The new villa elevator generally uses steel belt, which is like unfolding the steel wire rope, and then wrapping the rubber layer outside. This steel belt can be used even if a fire burns all the rubber layers outside. The steel belt was developed in 2000, and the technology is very mature.

所以说日常别墅电梯维保经常定期检查的话，钢丝绳基本不会出现全断或者脱落。一般十五天例行保养，季度，半年，年度，检查螺丝松动，除锈打油什么的。

Therefore, if the daily villa elevator maintenance is regularly checked, the steel wire rope will not be completely broken or fall off. Generally, 15 days of routine maintenance, quarterly, semi annual, annual, check for loose screws, rust removal and oiling.

根据统计，70%左右的别墅电梯故障都是在门系统上，这也是造成困人的主要原因，所以如果被困在电梯里的话，请不要靠近轿门并耐心等待救援人员到来，而且电梯轿厢不是封闭空间，不会有窒息危险。

According to the statistics, about 70% of the villa elevator failures are caused by the door system, which is also the main reason for trapping people. Therefore, if you are trapped in the elevator, please do not close to the car door and wait patiently for the rescue personnel to arrive. Besides, the elevator car is not a closed space, and there is no danger of suffocation.
