A detection method and detection device for elevator balance coefficient

Abstract

The invention discloses a detection method and device for an elevator balance coefficient. The method includes the steps that S1, after an elevator is initially installed, a counterweight of the elevator and an elevator car are located at the flush position; S2, constant torque F1 is output to control the elevator to run for one time period; and S3, the stable acceleration a during running of the elevator is obtained and substituted into a formula k=[F1+m'(g-a)] / [(g-a).Q], the elevator balance coefficient k is calculated, Q is the rated load of the elevator, g is the gravity acceleration, m' is the load of the elevator, and when the elevator is in a non-load state, m' is 0. The elevator balance coefficient can be rapidly and accurately detected, and the method and device for the elevator balance coefficient have the beneficial effects of being safe and reliable.

Description

technical field [0001] The invention belongs to the field of automatic detection of elevator systems, and in particular relates to a detection method and a detection device for an elevator balance coefficient. Background technique [0002] Elevator balance coefficient is one of the most important characteristic parameters of the elevator. It directly affects the overall performance of the elevator. The elevator balance coefficient has an important relationship with the safety performance and comfort performance of the elevator operation, and is also an important factor for the energy-saving and economical operation of the elevator. After the initial installation of each elevator, it is necessary to measure the balance coefficient of the elevator, and continuously optimize the counterweight of the elevator. A qualified elevator balance coefficient can not only ensure the stability and smoothness of the elevator during operation, but also prevent the car from Obvious shaking a...

Problems solved by technology

However, in this way, in most cases, special tools are required to measure parameter values ​​such as mass or torque, which increases additional hardware costs and introduces additional error sources, such as the accuracy error of the measurement tool and the elevator itself. Static friction, etc., and this method is mainly operated manually, which does not meet the needs of automation

[0005] The third is to use special measuring equipment for measurement. This method is often more accurate, but it also adds a lot of extra cost, and it needs to be carried everywhere, which is very inconvenient for debugging and maintenance.
