Description
本发明涉及一种电梯轿厢配件，尤其涉及一种防止电梯轿厢异常移动的装置。The present invention relates to an elevator car accessory, and more particularly to a device for preventing abnormal movement of an elevator car.
目前，中国已成为世界上拥有电梯最多的国家，每天有240万部电梯在运转，平均每五百多人就拥有一部电梯，而且每年以15％的速度在增长。电梯数量的增加，使维保工作量增大，许多电梯由于维保工作不到位，或电梯设备老化等原因导致电梯的安全事故增多，其中，开门情况下轿厢移动所引发的安全事故频繁发生，在电梯门开启状态下，传统电梯有两种方式防止电梯移动，一是主机制动器，但该装置作用于主机位置，不能防止钢丝绳在曳引轮上的打滑或者因该制动器本身故障引起的轿厢移动；二是轿厢安全钳，由于轿厢安全钳多采用渐进式的，且必须在超过额定速度的情况下由限速器引发其动作，因此制停距离过大，远远超出门区的安全允许范围。At present, China has become the country with the most elevators in the world. 2.4 million elevators are in operation every day. On average, every five hundred people have an elevator, and it is growing at a rate of 15% every year. The increase in the number of elevators has increased the maintenance workload. Many elevators have increased safety accidents due to inadequate maintenance work or aging of elevator equipment. Among them, safety accidents caused by car movement in the case of door opening occur frequently. In the open state of the elevator door, the traditional elevator has two ways to prevent the elevator from moving. First, the main engine brake, but the device acts on the host position, and cannot prevent the wire rope from slipping on the traction sheave or the car due to the failure of the brake itself. The car is moving; the second is the car safety gear. Because the car safety gear is mostly progressive, and the speed limiter must be triggered by the speed limiter when the rated speed is exceeded, the stopping distance is too large, far beyond the door zone. The range of security allowed.
