电梯导轨在电梯运行时为轿厢和对重装置提供导向, The elevator guide rail provides guidance for the car and counterweight device when the elevator is running, 还起到安全钳制动时的支撑作用,是电梯系统中的重要部件。 It also plays a supporting role when the safety clamp moves, which is an important part of the elevator system. 下面从电梯的安全性和舒适度两方面分析导轨的重要性。 The importance of guide rail is analyzed from the safety and comfort of the elevator. 1)安全性。电梯导轨影响电梯的安全的因素主要是导轨的材质。导轨材质过硬或不均匀(局部过硬),在安钳制动时夹紧将得不到足够的摩擦力,会造成制动失效,发生轿厢坠落这一电梯事故中最严重的工况。导轨也要有足够的强度,以保证安全钳制动时对轿厢及冲击力的支撑。 1) Security. The main factor affecting the safety of elevator guide rail is the material of guide rail. If the material of guide rail is too hard or uneven (local hard), enough friction force will not be obtained when clamping the guide rail, which will lead to brake failure and car falling, which is the most serious working condition in elevator accidents. The guide rail should also have enough strength to ensure the support of the car and impact force when the safety gear is braked. 2)舒适度。电梯导轨影响电梯舒适度的因素有以几个方面: 2) Comfort. There are several factors that affect the comfort of elevator a.导轨的连接精度:实心导轨的连接精度是由导轨的端部尺寸及阴阳榫的对称度来保证的,空心导轨及扶梯导轨的连接精度是由导轨的端部尺寸及形位公差来保证的,导轨的连接精度直接影响电梯运行的平稳性及舒适度。 a. Connection accuracy of guide rail: the connection accuracy of solid guide rail is guaranteed by the end dimension of guide rail and symmetry of male and female tenon; the connection accuracy of hollow guide rail and escalator guide rail is guaranteed by the end dimension and shape and position tolerance of guide rail, and the connection accuracy of guide rail directly affects the stability and comfort of elevator operation. b.导轨导向面粗糙度:导轨导向面粗糙度直接影响到导靴在导向面上能否平滑运行,同时也影响润滑油的储存,从而影响轿厢的运行质量。 b. Guide surface roughness: the guide surface roughness directly affects whether the guide shoe can run smoothly on the guide surface, and also affects the storage of lubricating oil, thus affecting the operation quality of the car. c.导轨的直线度及扭曲度:导轨上任何一点的弯曲及扭曲都会给轿厢一个侧力,影响轿厢上下的直线运动,使轿厢有晃动感,随着电梯速度提高,轿厢会有振动感,从而影响舒适度。 c. Straightness and distortion of guide rail: bending and twisting at any point on the guide rail will give a side force to the car, which will affect the linear movement of the car up and down, and make the car shake. With the increase of the elevator speed, the car will vibrate and affect the comfort. |
