Embodiment

[0041] A method for detecting elevator balance coefficients in this embodiment, such as figure 1 shown, including the following steps:

[0042] Step S1. Pre-detect the unit weight of the accompanying cable, the unit weight of the traction rope, the unit weight of the compensation chain, the rated load of the elevator, and the lifting height of the elevator car; these parameters are relatively easy to obtain. These parameters are detected in advance as known parameters for subsequent calculations.

[0043] Step S2. Confirm that the elevator car is empty, and start the automatic detection of the balance coefficient;

[0044] Step S3. Run the elevator car, and respectively record the torque current of the host moving up against the system resistance and the torque current of the host moving down against the system resistance when the elevator car is in the top, middle and bottom positions;

[0045] The specific steps are as figure 2 shown, including

[0046] Step S31. Run th...

Abstract

The invention relates to a method for detecting the balance coefficient of an elevator. By means of the method, the problems that in the prior art, it is troublesome to obtain the balance coefficient, and manpower and material resources are wasted are solved. The method comprises the steps that the torque current of a main engine is controlled, recorded and processed when the elevator is in a non-load state and is at different storeys through an elevator driving and controlling system, and the balance coefficient of the elevator is obtained directly through formula derivation. The method has the advantages that based on an existing elevator car control system, no additional hardware device is needed; an elevator car does not need to be loaded, and the waste of a large number of manpower and material resources is avoided. The method for detecting the balance coefficient of the elevator is automatically executed directly through the elevator control system, little manual operation is needed, detection is simple and convenient, the efficiency is high, and a detection result is accurate.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator balance coefficient detection method that saves manpower and material resources and is easy to operate. Background technique [0002] Most elevators are driven by traction. The car and the counterweight of the traction elevator are respectively suspended on both sides of the traction sheave through the steel wire rope / steel belt. And counterweight exercise. The balance factor is an important performance index of the traction drive elevator. The introduction of counterweight can effectively balance the weight of the car itself and the load inside the car, thereby greatly reducing the load of the traction main engine. In the actual elevator installation and commissioning process, there are often many ways to obtain the elevator balance coefficient, but they are often cumbersome or the obtained elevator balance coefficient is not accurate enough. [0003] At present...
