The invention relates to an elevator maintenance evaluation method which is characterized in that a traction wheel of a traction machine is connected with an encoder, and the encoder is connected with an upper computer; the elevator overhaul evaluation method comprises the following steps that firstly, elevator overhaul parameter values are input into an upper computer; the elevator car is stopped at the same horizontal position as the elevator counterweight device; when the elevator car is static, the upper computer calculates the torque T1 of the traction machine brake on the traction wheel; secondly, under the condition that a traction wheel is tightly held by a traction machine brake, the torque output by the traction machine is gradually changed from small to large; when it is detected that the pulse signal output by the encoder exceeds a preset value, the torque output by the traction machine at the moment is recorded as T2 and input into the upper computer; 3, the upper computer calculates the braking torque T3 of the traction machine brake; the upper computer sets a brake torque first early warning value of the traction machine brake as Tx in advance; and when T3 is smaller than Tx, the upper computer judges that the braking effect of the traction machine brake is poor. According to the invention, the braking capacity of the traction machine can be accurately judged.

    本发明涉及一种电梯检修测评方法,曳引机的曳引轮上连接有编码器,编码器连接上位机;电梯检修测评方法包括以下步骤:步骤一、在上位机上输入电梯检修参数值;将电梯轿厢停至与电梯对重装置同一水平位置;在电梯轿厢静止不动时,上位机计算所述曳引机制动器在曳引轮上的扭矩为T1;步骤二、在曳引机制动器抱紧曳引轮情况下,使曳引机输出的扭矩由小到大逐渐变化;当检测编码器输出脉冲信号超过预设值时,记录此时曳引机输出的扭矩为T2输入上位机;步骤三、上位机计算曳引机制动器的制动扭矩为T3;上位机事先设定曳引机制动器的制动扭矩第一预警值为:Tx;当T3<Tx时,上位机判断该曳引机制动器的制动效果不良。本发明能够准确判断曳引机的制动能力。
