Problems solved by technology

At present, the traditional dynamic current method is commonly used at home and abroad to test the elevator balance coefficient. Generally, the parameters such as the voltage and current of the traction motor during the operation of the elevator are measured, obtained through calculation and drawing, and the measurement is in accordance with the requirements of the elevator supervision and inspection regulations. , it is necessary to apply different rated loads to the elevator for many times. In order to test this parameter, the inspectors have to spend a long time waiting for the relevant personnel to move the load of the weights many times. Inaccurate, there is a large system comprehensive error, it is difficult to obtain a more accurate elevator balance coefficient, the specific reasons are as follows:
[0003] 1. At the moment when the counterweight and the car run to the same horizontal position, there are large reading...

Embodiment Construction

[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. Embodiment: a method for testing the balance coefficient of an elevator by using the hand wheel of the elevator, comprising the steps of:

[0039] 1) After the elevator load operation test is completed, install the cranking torque test device on the manual cranking handwheel of the elevator, and use the cranking torque test device to test the cranking torque values ​​A1, A2 and A3;

[0040] 2), test data processing, according to the principle of torque balance, calculate the step of the relationship formula K=i×(A2+A3) / 2(A1+A2) between the cranking torque value and the elevator balance coefficient, where i is the test load and rated Scale factor for loads.

[0041] The step 1) is specifically completed by the following steps:

[0042] ①, see figure 1 After the elevator load operation test is completed, the elevator runs and stops a...

Abstract

The invention relates to the technical field of elevator test, and provides a method for testing elevator balance coefficient by the aid of an elevator handwheel, which is time-saving, labor-saving, simple in operation and small in systematic composition error and can be used for conveniently, accurately and rapidly measuring the elevator balance coefficient. The method includes the steps: mounting a handwheel torque testing device on the elevator handwheel and testing handwheel torque values A1, A2 and A3 by the aid of the torque testing device after an elevator load operating test; and calculating the relation formula K=iX(A2+A3)/2(A1+A2) of the handwheel torque values and the elevator balance coefficient according to torque balance principle, wherein the i refers to the proportionality coefficient of test load and rated load.

Description

technical field [0001] The invention relates to the technical field of elevator detection, in particular to a method for testing the balance coefficient of an elevator by using a hand wheel of an elevator pan. Background technique [0002] Elevator balance coefficient is an important parameter that needs to be measured on-site during the installation, acceptance and use of the elevator. It is also an important parameter related to the life, reliability, comfort and energy saving of the elevator. At present, the traditional dynamic current method is commonly used at home and abroad to test the elevator balance coefficient. Generally, the parameters such as the voltage and current of the traction motor during the operation of the elevator are measured, obtained through calculation and drawing, and the measurement is in accordance with the requirements of the elevator supervision and inspection regulations. , it is necessary to apply different rated loads to the elevator for ma...
