一种电梯运行稳定装置
摘要：
本实用新型公开了电梯领域内的一种电梯运行稳定装置，包括安装在电梯马达上的旋转编码器一，旋转编码器一的输出端与变频器的输入端相连，变频器的输出端与PLC控制单元的输入端相连，PLC控制单元的输出端与执行单元的输入端相连，PLC控制单元的输入端还与安装在限速器上的旋转编码器二的输出端相连。通过将两编码器检测到的设定脉冲数据和实际脉冲数据反馈给PLC控制单元进行比较，当脉冲数据相差超出设定值时，能及时报警以及选择较近楼层停靠，进行维修，排除了可能存在的故障隐患。本实用新型可用于确保电梯稳定运行中。
摘要（英）：

The utility model discloses a running stabilizing device for an elevator in the field of elevators. The running stabilizing device comprises a first rotary encoder, wherein the first rotary encoder is arranged on an elevator motor, the output end of the first rotary encoder is connected with the input end of a frequency converter, the output end of the frequency converter is connected with the input end of a programmable logic controller (PLC) control unit, the output end of the PLC control unit is connected with the input end of an execution unit, the input end of the PLC control unit is also connected with the output end of a second rotary encoder, and the second rotary is arranged on a speed limiter. In the running stabilizing device, setting pulse data detected by the two rotary encoders and actual pulse data are fed back to the PLC control unit for comparison, when the difference between the pulse data is beyond a set value, the elevator can timely give out warning and selects a nearer floor to stop for maintenance, and a probable-existence potential fault is eliminated. The running stabilizing device can be used for ensuring stable running of the elevator.
