The invention discloses a device for improving the leveling precision of an elevator, and the device comprises a linear weighing device which is used for detecting the real-time weight of a lift car; the linear weighing device comprises an elastic device and a controller capable of outputting linear voltage; the car suspension device is connected with the car and the motor through a suspension steel wire rope; the hoistway position system is used for detecting the real-time position of the lift car; and the control compensation device is used for receiving the linear voltage value from the linear weighing device, calculating the elongation of the suspension steel wire rope when the elevator car stops, and controlling the motor to move or stop in real time, so that the elevator car can select a position which is a preset distance above or below the flat layer according to the real-time weight of the elevator car when the elevator car stops at the station layer. The problem that the lifting or sinking amplitude is too large when passengers enter and exit from the lift car due to extension of the suspension steel wire rope is solved, the reliability is high, and the cost is low.

    本发明公开了一种提高电梯平层精度的装置,包括:线性称量装置,用于检测轿厢实时重量;所述线性称量装置包括弹性装置与能够输出线性电压的控制器;轿厢悬挂装置,通过悬挂钢丝绳连接轿厢与电动机;井道位置系统,用于检测轿厢的实时位置;控制补偿装置,接收来自线性称量装置中的线性电压值及计算悬挂钢丝绳在轿厢站停靠时的伸长量,实时控制电动机运动或停止,使得轿厢在站层停靠时能够根据停靠时轿厢的实时重量选择停靠平层之上或之下预设距离的位置。本发明旨在于减小因悬挂钢丝绳伸长问题造成乘客出入轿厢时抬升或者下沉幅度过大的问题,可靠性高,成本低。
