重慶升降平臺(tái)的變速部分和錐鼓式限速器的離心制動(dòng)部分，是封閉式的，其他部分是開(kāi)啟式的。封閉部分不易檢查，現(xiàn)場(chǎng)只能看一下變速箱是否漏油．錐鼓式限速器名牌上標(biāo)注的檢測(cè)日期是否過(guò)期。錐鼓式限速器必須經(jīng)有法定檢測(cè)資質(zhì)的安全，檢測(cè)機(jī)構(gòu)定期檢測(cè)并做鉛封，使用單位不準(zhǔn)隨意調(diào)整。
Centrifugal brake part shifting part of Zhejiang and freight elevators cone drum speed limiter is closed, the other part is on style. Closed portion is not easy to check whether the site can only look at the gearbox oil leak. Cone drum speed limiter date marked on the nameplate detect whether expired. Cone drum must be approved by the governor has the statutory safety testing qualification, periodic testing and testing organizations do seals, are not allowed to be adjusted using the unit.

升降平臺(tái)開(kāi)啟部分的檢查與檢測(cè)不同，因安全檢查涉及的點(diǎn)多面廣，時(shí)間有限，相對(duì)于的安全檢測(cè)要粗放一些。一般情況下不帶儀器，全憑經(jīng)驗(yàn)觀察：主要檢查各傳動(dòng)部位的間隙不能過(guò)大，一般控制在0.2～0.5mm左右，齒輪與齒條吻合時(shí)齒底的間隙為2.0mm。嚙合間隙過(guò)大或齒輪齒條磨損嚴(yán)重都是很危險(xiǎn)的，貨梯的運(yùn)行和制動(dòng)力都要通過(guò)齒輪齒條傳遞。嚙合深度不夠、磨損嚴(yán)重或軸向錯(cuò)位過(guò)大，都會(huì)使嚙合面積減小而造成齒輪齒條強(qiáng)度降低，發(fā)生斷齒事故，在實(shí)際安全檢查過(guò)程中發(fā)現(xiàn)。
Inspection and testing different parts of Zhejiang freight elevator opened, due to security checks involving over a broad area, limited time, with respect to the safety testing freight elevator to the extensive number of Zhejiang. Under normal circumstances without instruments depends on empirical observations: the gap is mainly check the transmission parts can not be too large, generally controlled at about 0.2 ~ 0.5mm, consistent with the rack gear tooth bottom clearance for 2.0mm. Backlash is too large or badly worn gear rack is very dangerous, running and braking Zhejiang freight elevator must pass through the rack and pinion. The depth of engagement is not enough, badly worn or axial dislocation is too large, will make the engagement area is reduced causing the rack and pinion strength decreases, the occurrence of the accident broken teeth, was found in the actual security check process.

檢查過(guò)程中應(yīng)注意導(dǎo)輪與齒條的間隙不應(yīng)太大，一般在0.2～0.5mm，滾輪與導(dǎo)軌的間隙也要控制在0.2～0.5mm，電梯運(yùn)行應(yīng)該平穩(wěn)，無(wú)異響，無(wú)明顯的震動(dòng)。
Zhejiang freight elevator inspection process should pay attention to the guide wheel and rack space should not be too large, generally 0.2 ~ 0.5mm, the wheel and the rail gap should be controlled at 0.2 ~ 0.5mm, the elevator should be smooth, no abnormal sound, no significant vibration.
