固定升降機(jī)http://www.qdysj.net/原來(lái)的安裝掛線要求測(cè)量只給定中心線與主軸中心線即可，通過(guò)以往的安裝證明，這種十字掛線法容易形成累計(jì)偏差誤差。中心線與提升中心線水平距離在支胎中就很難掌握，由于胎板釘有許多支柱，往往擋住測(cè)量通路，用米尺直接測(cè)量較困難，只有采取分段法測(cè)量，這樣就產(chǎn)生較大的累計(jì)偏差。就是能用尺子直接測(cè)量，如所測(cè)量方向如與雙提中心線不垂直，或者兩方面不平行都導(dǎo)致固定升降機(jī)中心線存在誤差，其余的如電動(dòng)機(jī)中心線產(chǎn)生的累計(jì)偏差將會(huì)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.
　   
通過(guò)對(duì)固定升降機(jī)http://www.qdysj.net/安裝易出現(xiàn)的誤差的分析，采取行之有效的控制產(chǎn)生誤差的對(duì)策，采取的對(duì)策是采用多控制線安裝法，即在測(cè)量人員掛線時(shí)，除掛好原主軸中心線與提升中心線外，還應(yīng)增中心線及電動(dòng)機(jī)中心線。在支胎過(guò)程中，一些關(guān)鍵尺寸都從控制線開(kāi)始量。使固定升降機(jī)鹼基礎(chǔ)偏差、天輪基礎(chǔ)偏差及機(jī)械主體安裝偏差都嚴(yán)格控制在設(shè)計(jì)要求的范圍之內(nèi)，特別是有效地控制累計(jì)誤差的產(chǎn)生安裝工程的成敗起著關(guān)鍵性的作用。
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.
