Method for measuring elevator equilibrium coefficient

Abstract

The invention provides a method for measuring elevator equilibrium coefficient, which has short testing time, high testing efficiency, low cost and can greatly reduce labor intensity of workers. Whenthe elevator is instructed to ascend at uniform speed, the torque of a traction motor is detected in real time and recorded as an empty-load uniform ascending torque at the moment when the suspensionpoint of a wire rope or a driving belt of an elevator car and the suspension point of a wire rope or a driving belt of the counterweight are at the same horizontal line; when the elevator is instructed to descend, the torque of the traction motor is detected in real time and recorded as an empty-load uniform descending torque at the moment when the suspension point of a wire rope or a driving beltof the elevator car and the suspension point of a wire rope or a driving belt of the counterweight are at the same horizontal line; and the empty-load uniform ascending torque and the empty-load uniform descending torque are substituted into an elevator equilibrium coefficient calculation expression so as to calculate the elevator equilibrium coefficient.

Description

technical field [0001] The invention relates to the technical field of elevator detection, in particular to a detection method for an elevator balance coefficient. Background technique [0002] In order to ensure the safe operation of the elevator, it is necessary to measure the balance coefficient during the installation and acceptance of the elevator to verify whether it meets the national standards. The existing detection method for the elevator balance coefficient is generally to apply weights in the car Such as the disclosed torque test method and test device for the elevator balance coefficient disclosed in the patent application CN 101226096A) or by special testing tools for detection (such as a kind of elevator balance coefficient disclosed in the patent of CN 100391821C with the authorized announcement number measurement method), the detection methods of the above-mentioned elevator balance coefficients all have the disadvantages of high labor intensity and long mea...
