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
The present invention relates to a kind of elevator technology field, especially relate to a kind ofly to use manpower and material resources sparingly, easy to operate balance coefficient of elevator method of inspection.
Background technology
The type of drive of elevator mostly is tractive driving mode.The car of towed elevator and counterweight hang on the both sides of traction sheave respectively by steel rope/steel band, due to steel rope/there is friction force between steel band and traction sheave when traction sheave rotates, thus drive steel rope/steel band and counterweight motion to get up.Equilibrium factor is the important performance indexes that traction-type drives elevator, and introducing counterweight can carry out actv. balance to the load in car own wt and car, thus the load that traction main frame is run alleviates greatly.In elevator running Installation and Debugging process, the method obtaining balance coefficient of elevator often has a variety of, but often balance coefficient of elevator that is cumbersome or that obtain is accurate not.
The acquisition methods of balance coefficient of elevator conventional at present has following several.1. direct weight method, namely direct to lift car, the parts such as counterweight are weighed, thus directly calculate balance coefficient of elevator; 2. current method, namely by adding different weight percentage load-carrying in lift car, and after recording the current value in ascending for elevator, descending process, the current curve under the different load condition of drafting elevator in uplink and downlink situation, the point of crossing of two curves had both been balance coefficient of elevator; 3. hand turning method, namely by loading the load-carrying presetting equilibrium factor in car, hand turning, by feeling to increase and decrease car weight, thus confirms the adjustment amount of counterweight, and then the equilibrium factor that realization is preset.
But existing equilibrium factor acquisition methods also exists some defects, as said method 1 needs to obtain lift car, the weight of counterweight; Method 2 needs to carry load-carrying in car; Then there is the not high problem of precision in the equilibrium factor that method 3 obtains, the method needs to settle certain load-carrying equally in car simultaneously.They all need loaded weight in phase lift car, there is the problem of wasting manpower and material resources, and it is not very convenient to operate.
Summary of the invention
The present invention mainly solves in prior art and obtains equilibrium factor Measures compare trouble, wasting manpower and material resources, and also there is the not high problem of precision, provide one use manpower and material resources sparingly, easy to operate, the balance coefficient of elevator method of inspection that precision is high.。
Above-mentioned technical matters of the present invention is mainly solved by following technical proposals: a kind of balance coefficient of elevator method of inspection, comprises the following steps:
S1. trailing cable unit weight, hoist ropes unit weight, compensated chain unit weight, elevator rated load, lift car hoisting depth is detected in advance; The specification that cable unit weight, hoist ropes unit weight, these numerical value of compensated chain unit weight adopt according to them can easily obtain.Elevator rated load, lift car hoisting depth also can easily be obtained by elevator specification.Lift car hoisting depth refers to that lift car can promote the highest height, is fixed value.
S2. confirm that lift car is unloaded, open equilibrium factor and automatically detect;
S3. run lift car, record respectively lift car be in top layer, centre and bottom position time uply overcome the engine torque electric current of systemic resistance movement and the descending engine torque electric current overcoming systemic resistance movement;
