固定升降机安装中如何避免出现误差?

固定升降机http://www.jnyuexiang.com/原来的安装挂线要求测量只给定中心线与主轴中心线即可,通过以往的安装证明,这种十字挂线法容易形成累计偏差误差。中心线与提升中心线水平距离在支胎中就很难掌握,由于胎板钉有许多支柱,往往挡住测量通路,用米尺直接测量较困难,只有采取分段法测量,这样就产生较大的累计偏差。就是能用尺子直接测量,如所测量方向如与双提中心线不垂直,或者两方面不平行都导致固定升降机中心线存在误差,其余的如电动机中心线产生的累计偏差将会更大。
Fixed lifts original installation hung required to measure only given spindle centerline to centerline, by the previous installation has proved that this method is easy to form cross-thread the cumulative deviation errors. Centerline and upgrading the centerline horizontal distance in supporting the womb is difficult to grasp, because the fetus has many pillars nail plate, often blocking the measurement path, the more difficult to directly measure with a meter stick, only to take sub measurement, thus creating a greater cumulative deviation. Is the ruler can be measured directly, such as the measurement direction is not perpendicular to the center line and double-lift, or both are not parallel to the centerline of the presence of error results in a fixed elevator, the rest of the motor as the cumulative deviation of the center line produced will be greater.
    
通过对固定升降机http://www.jnyuexiang.com/安装易出现的误差的分析,采取行之有效的控制产生误差的对策,采取的对策是采用多控制线安装法,即在测量人员挂线时,除挂好原主轴中心线与提升中心线外,还应增中心线及电动机中心线。在支胎过程中,一些关键尺寸都从控制线开始量。使固定升降机硷基础偏差、天轮基础偏差及机械主体安装偏差都严格控制在设计要求的范围之内,特别是有效地控制累计误差的产生安装工程的成败起着关键性的作用。
Through the analysis of fixed lift installation error prone, and take effective countermeasures to control produce errors, measures are taken to control the use of multi-line installation method, which hung in the measurement of personnel, in addition to the original spindle centerline and hang enhance the centerline, but also increase the centerline and motor centerline. In support fetal process, some key dimensions are increased from the beginning of the line of control. The fixed lift alkaline base bias, bias-day basis and mechanical main wheel misalignment are strictly controlled in the range of design requirements, particularly effective in controlling the success of the cumulative error generated installation engineering plays a key role.
