| 长期以来，人们对在用电梯导轨安装存在质量问题产生轿厢水平方向振动而造成电梯乘载品质差的问题感到棘手。因电梯的导轨是整个轿厢运动的基准，包括了轿厢运动中各部件与整列厅门的间隙要求及中心位置要求，如基准线改动，后果难以想象。 For a long time, people have difficulty in installing quality problems in elevator guide rail, causing horizontal vibration of cars, resulting in poor quality of elevator ride. The elevator's guideway is the benchmark of the whole car movement, which includes the clearance requirements of the components and the whole hall door in the car movement and the central location requirements, such as the baseline change, and the consequences are unimaginable. 1电梯导轨的正确安装 1 correct installation of elevator guide 1．1待装电梯导轨的检验电梯导轨(特别是轿厢导轨)在安装前须检查每根待装导轨的直线度不应超出l／6000，整根导轨其最大弯曲不超过0．6ram，并在任1000mm中弯曲度不应超出0．3ram(这对于现场导轨的正确堆放、搬运等都提有一定的要求)；工地检测采用2块磁铁吸压一根细线在磁铁与金属垫片间，垫片再吸附与导轨被测工作面并将线拉直进行测量；水平测量时应考虑导轨自重所引起的弯曲，测量侧向工作面时应平躺、测量顶端工作面时应侧躺；扭曲校检可用两磁力水平、垂直仪吸附侧向工作面检查各段相对扭曲或将导轨卧躺用两水平仪测量两接导面相对水平。 1.1 inspection of elevator guide rail of elevator guide rail to be installed (especially car rails) must be inspected to be installed each guide rail straightness should not exceed L / 6000 before installation, the whole track the maximum bending of not more than 0.6ram, and at 1000mm in bending should not exceed 0.3ram (the right guide rail for the scene handling all piled up, there are certain requirements); site inspection by using 2 pieces of magnet suction pressure of a thread in the magnet and the metal gasket, gasket and adsorption and guide the measured working surface and line straightening measurements; level measurement should be taken into account when bending rail caused by measuring weight, lateral working face should be flat top, measuring working face should be the side lying check; twisted by two horizontal and vertical magnetic adsorption instrument lateral face check each relative distortion or lying two is connected with the guide rail measuring surface relative to the level two level. 若弯曲过大应在校正后方可安装；现场直线度、扭曲校正，只要点把握得准并不难，若存在有严重扭曲、弯头又实在无法校直情况可考虑更换或将其安装于井道最高或最低处。 If the bending is too large, it can be installed after correction. The straightening and straightening of the field is not difficult as long as the point is grasped accurately. If there is serious distortion and elbow, it can not be straightened directly, it can be considered to replace or install it in the highest or the lowest part of the well. 提吊导轨应采用绳索竖装，采用3人搬运并搬运时避免弹跳，严禁采用绳索索于导轨中心或2端处平行提吊。 The lifting guide rail should adopt the rope vertical installation, avoid jumping when carrying and carrying 3 people, and strictly prohibit the use of rope cable in the center of guide rail or parallel lifting at the 2 end. 导轨由底坑向上逐根立起(通常以雄口朝上，因雌口朝上易产生轿厢安全钳动作时啃坏导轨接口侧面)，安装前应检查各导轨连接口是否损伤并将其清洗干净。 The guide rail is erected from the bottom pit to the top. (usually the male mouth is upwards. The female rail is prone to generate the side face of the guide rail when the female joint is upwards. The inspection should be done before the installation of the safety joint is damaged and cleaned. 1．2导轨正确的安装方法(1)以铅垂线为基准，检查逐根安装好的导轨与铅垂线的误差值，并逐根安装，逐根进行调整。方法为：支架处导轨校正到位一接导口直线度校正一支架处导轨校正等，避免(特别是高层)待导轨全部安装好后，如没进行调整(整列导轨从底至顶呈无数折线，折线长度大于直线)，而导轨的预定位摩擦及自重的存在，使其下部导轨在校正时无法伸张造成弯曲、扭曲或虽已校正仅免强在导轨支架处，而整列导轨内部存在着弯曲、扭曲应力使各支架中间部分的导轨产生变形，特别在接导板处，弯力足够大时使接导板产生变形而完全无法达到导轨安装检验标准要求。 The correct installation method of 1.2 rail (1) with a plumb line as the base, the error checking by rail and the plumb line installed the value of the root, and by the root installation, adjusted by the root. Methods: the stent in place with a guide port rail correction a support rail straightness correction correction, avoid (especially high-rise) to guide all installed, if not adjusted (the entire column guide rail from bottom to top in numerous line, line length is greater than the straight line), and guide a friction and weight the existence of the school, the lower track caused by the bending distortion or has only correction on the rail bracket from not done is, and the entire column guide exists inside the bending and twisting stress to guide the support of the middle part of the deformation, especially in the plate, bending force is large enough to meet the guide deformation and completely unable to meet inspection standards require the installation guide. 为了避免安装的导轨(无数段折线)在调整时因预定位摩擦及自重无法使折线至直线的变化而又不希望安装、校正相问进行。可在安装第一根导轨时底部垫起30～50mm，然后安装导轨并预紧压导板(如采用定位型压导板对导轨不产生较大摩擦压力则不能采用此工艺)。校正时拿去底部垫块使导轨逐根下滑并逐根校正。校正步骤同(1)。 In order to avoid the installation of guideway (numerous lines), when adjusting, due to pre positioning friction and self weight, it is not possible to change the broken line to the straight line, but do not want to install and correct it. When installing the first guide rail, the bottom should be 30 ~ 50mm, then install the guide way and pre press the guide plate (if the positioning pressure guide plate does not produce greater friction pressure on the guide rail, it is not possible to use this process). When correction is taken, the bottom pad is taken to make the guide slide down and correct by root. The correction step is the same as (1). 1．3导轨的校正检查以铅垂线为基准，检查、校正每根轿厢导轨正、侧工作面垂直偏差应小于0．6／5000ram。一对导轨的平行度检查可用2块小磁铁吸、压一根细线与一对导轨侧工作面之间，同时将线拉直，采用300ram刀口直尺紧贴导轨侧面检查一对导轨的平行度；轿厢导轨平行度要求为2／1000(企业标准)，即300mm刀口直尺紧贴导轨侧面约50ram，另250ram长度作为偏转放大的顶端与绷紧的直线间距应小于0．5ram(2／1000要求)；也可采用激光导轨平行度校正仪可更直观地从标尺聚光点上看出偏差。上述定位方法合二为一，校正导轨在各支架处的相对正确位置。 1.3 guide to plumb line calibration checks as reference, check and correction of each car guide rail, vertical side face deviation should be less than 0.6 / 5000ram. A pair of guide rail parallel check available 2 magnets between suction and pressure of a thread and a pair of guide rails side face, while the line straight, with 300ram close to the guide rail side knife edge ruler inspection of parallelism; car guide rail parallel degree is 2 / 1000 (enterprise standard), 300mm close to the knife edge ruler rail side is about 50ram, the other 250ram line spacing and length as the top of the tight deflection amplifier should be less than 0.5ram (2 / 1000); also can use laser guide parallelism correcting instrument can more intuitive to see the deviation from the scale points of light. The above positioning method is combined to correct the relative correct position of the guide rail at each bracket. 轿厢导轨的2导轨接口直线度在梯速小于2m／s以下时，采用长度为500ram的刀口直尺进行校直(梯速大于2m／s的应适当增加刀口直尺有效长度)，用灯光在刀口直尺背部加以检测(如中心面偏差超出要求范围可用金属垫片加以垫正)。要求在整个500ram范围内塞缝间隙不大于0．05ram(须在导轨全部校正后方可考虑对接口略作修光)。 A car guide rail 2 rail interface straightness in lift with speed less than 2m / s, the length of the knife edge ruler 500ram (ladder straightening speed is greater than 2m / s should be appropriate to increase the effective length to be detected in the knife edge ruler), back light knife edge ruler (such as the center plane deviation beyond the range of available metal requirements the gasket to be pad positive). In the scope of the entire 500ram plug gap is not greater than 0.05ram (to be in full before considering the light rail correction repair interface slightly). 以上方法须由下而上逐步校正，经检查合格后再进行上一档的校正。如遇接导板时，应先校正接导板处2导轨的正面及侧面的直线度，校直后再进行下一步的工作。 The above method to the bottom-up gradually correction, after inspection and correction on file. If the guide plate is connected to the guide plate, the straightness of the front and side sides of the 2 guide guide plate should be corrected first, and then the next step should be carried out. 用上述方法校正导轨其校验不应少于2次。导轨校正时应使其目测尺寸基本为0刻度。校正后一对轿厢导轨的中心面、侧面以及间距偏差在整个高度上不应超过1iT1ITI(包括支架中间位置及接导板位置)。导轨安装过程中的各个环节应提倡一次到位。 The calibration of the guide rail with the above method should not be less than 2 times. When the guide is corrected, its visual size should be basically 0 scale. After correction, the deviation of the center, side and spacing of a pair of car guideways should not exceed 1iT1ITI, including the middle position of the bracket and the position of the guide plate. Each link in the guide rail installation should be promoted once in place. 2在用电梯轿厢导轨的校正本方法为采用井道内绷线法来对在用电梯的整列导轨直线度进行校正(因为此时可能由于建筑物的正常倾斜等原因已很难再进行垂直校正，除非移动层门位置)，操作者站在轿顶以轿厢检修速度由下至上对整列导轨进行校正。 2 in the original school method for elevator guide rail for the hoistway bastings to the lift the entire column of straightness correction (because this may be due to the building's normal tilt reason has been difficult to carry out vertical correction, unless the mobile door operator position), standing on the top of car in the car maintenance speed from the bottom of the entire column of track correction. 如上所述，不正确的导轨安装使导轨中存在着较大的内应力在电梯运 As mentioned above, the incorrect guide rail installation makes a larger internal stress in the elevator in the elevator. |
