Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0032] It should be noted that when an element is referred to as being “fixed on”, “disposed on” or “installed on” another element, it may be directly on the other element or there may be an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be an intervening element at the same time; the specific way that one element is fixedly connected to another element can be realized through existing technologies, and will not be discussed here. To repeat it agai...

Abstract

The invention relates to an elevator traction condition evaluating method and a system thereof. The system comprises a control system, a traction system and a rotary encoder, wherein the traction system comprises a traction machine, a traction wheel matched with the traction machine and a steel wire rope in driving connection to the traction machine and matched with the traction wheel slidably, and the steel wire rope is connected to a car; and the rotary encoder is arranged on the traction wheel. So far, the slip amount and a friction force value of the steel wire rope detected and calculatedare specific accurate numerical values. The accurate slip amount and friction force value of the steel wire rope can provide accurate data to the control system to calculate a current traction condition of an elevator to further pre-diagnose the traction condition of the elevator accurately, so that it is ensured that the elevator operates safely and reliably, and it is also convenient for staffto maintain and repair the elevator.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator traction condition evaluation method and system thereof. Background technique [0002] At present, most of the elevators in use on the market use traction technology to work, so the traction conditions will directly determine whether the elevator can run safely and reliably. The evaluation index of traction conditions is mainly the slippage and friction between the wire rope and the traction sheave after emergency stop. When the elevator runs at high speed and stops suddenly, the steel wire rope will slip on the traction sheave. At this time, the recorded value of the rotary encoder on the traction machine cannot accurately reflect the actual position data of the car, and the elevator system cannot directly pass the rotary encoder. The device records the value to judge the slippage of the elevator. Since the amount of slippage cannot be accurately calculated, it c...
