Quantitative test device and method for high-speed elevator flat cable resilience

Abstract

The invention discloses a quantitative test device for high-speed elevator flat cable resilience. The device comprises a rigid bracket, a test iron rod, a scale, a fixed plate, a tested flat cable anda motion camera, wherein the rigid bracket is fixed on a rigid base and includes left and right vertical columns and a top beam; the test iron rod is horizontally suspended on the top beam of the rigid bracket through the two steel ropes; the scale is vertically mounted in the middle of the rigid base and located on the rear side of the test iron rod; the fixed plate is mounted on the right column of the rigid bracket in an up-down moving manner; the tested flat cable is fixed on the inner side surface of the fixed plate in manner that the width direction is vertical and the length directionis horizontal; and the motion camera is located at an intersection position between a center vertical line of the scale and the lowest horizontal line of the test iron rod. The invention furthermore discloses a quantitative test method for high-speed elevator flat cable resilience. The test method is capable of accumulating more dynamic data of high-speed traveling cables, and is beneficial for improving the design and manufacture levels and quality control level of the high-speed traveling cables.

Description

technical field [0001] The invention relates to a high-speed elevator flat cable resilience quantitative testing device and method. Background technique [0002] In the era of rapid development of high-rise buildings, more and more landmark high-rise buildings have sprung up, and the supporting elevators have also greatly increased the operating speed to meet the needs of high-rise and super high-rise buildings. For example, one of the two high-speed elevators in the Shanghai Tower directly reaches the 118th floor with a journey of 546 meters at a speed of 20m / s, and the other at 18m / s; Guangzhou East Tower (Chow Tai Fook Financial Center) has a journey of 530 meters and goes directly to the 95th floor The speed of the two high-speed elevators reaches 21m / s. As the key component of the elevator system, the accompanying cable also increases the running speed accordingly to meet the needs of high-speed elevators. [0003] Since the ultra-high-speed accompanying cable is to r...
