升降機(jī)械液壓系統(tǒng)工作原理與技術(shù)要求

升降機(jī)械液壓系統(tǒng)的工作原理與技術(shù)要求。
國(guó)內(nèi)高空作業(yè)平臺(tái)的結(jié)構(gòu)形式主要有剪叉式、套筒油缸式、桅柱式、臂架式和桁架式，其中剪叉式、套筒油缸式、桅柱式和桁架式均是垂直升降式結(jié)構(gòu)。

現(xiàn)以在建筑行業(yè)中常用的GKT曲臂式高空液壓作業(yè)平臺(tái)(以下簡(jiǎn)稱平臺(tái))爲(wèi)例，它是一種比較典型的高空作業(yè)設(shè)備。平臺(tái)的作用是將人員和設(shè)備從地面送達(dá)近幾十米高的建筑外牆上或高層建筑上，從事張貼、檢修、安裝等工作，因此該設(shè)備在工作時(shí)對(duì)保證人員的安全提出很高的要求。

液壓平臺(tái)由底座、轉(zhuǎn)臺(tái)、臂架以及工作臺(tái)四個(gè)部分組成。其工作原理：(1)通過(guò)轉(zhuǎn)臺(tái)上的液壓馬達(dá)驅(qū)動(dòng)齒輪旋轉(zhuǎn)，并齧合固定在底座上的大齒輪産生回轉(zhuǎn)運(yùn)動(dòng)來(lái)調(diào)整工作臺(tái)的力位。通過(guò)連接在轉(zhuǎn)臺(tái)臂架內(nèi)的伸縮油缸的運(yùn)動(dòng)，推動(dòng)多級(jí)臂架內(nèi)的機(jī)械聯(lián)動(dòng)機(jī)構(gòu)的伸縮來(lái)調(diào)整工作臺(tái)與底座的距離。(3)通過(guò)變幅油缸的運(yùn)動(dòng)，使臂架與轉(zhuǎn)臺(tái)的回轉(zhuǎn)平面的俯仰角發(fā)生變化。(4)通過(guò)這3種動(dòng)作的組合和協(xié)調(diào)來(lái)完成工作臺(tái)的空間定位。(5)通過(guò)下調(diào)平油缸和上調(diào)平油缸的協(xié)調(diào)運(yùn)動(dòng)。使工作臺(tái)在臂架俯仰時(shí)保持水平。

當(dāng)液壓系統(tǒng)失效時(shí)的情況和液壓系統(tǒng)因停電或電氣等故障發(fā)生停車的情況?？紤]平臺(tái)正在工作時(shí)液壓系統(tǒng)可能出現(xiàn)的故障：首先從平臺(tái)液壓系統(tǒng)本身的結(jié)構(gòu)來(lái)看，由于結(jié)構(gòu)複雜和管路衆(zhòng)多，其中有數(shù)根長(zhǎng)達(dá)幾十米的軟管。機(jī)器作業(yè)時(shí)液壓升降機(jī)構(gòu)運(yùn)動(dòng)，高壓膠管反複進(jìn)行繞曲運(yùn)動(dòng)，容易産生疲勞破斷。升降機(jī)的負(fù)載變化較大液壓系統(tǒng)內(nèi)將産生液壓脈動(dòng)，脈動(dòng)壓力達(dá)到一定值時(shí)，高壓膠管會(huì)産生破斷。其次系統(tǒng)閥件在運(yùn)行過(guò)程中失效，會(huì)造成系統(tǒng)運(yùn)行失效而被迫停車。

根據(jù)以上的分析，在設(shè)計(jì)中對(duì)升降機(jī)械液壓系統(tǒng)針對(duì)性地提出了一些具體的技術(shù)要求。針對(duì)液壓系統(tǒng)失效的情況由于液壓缸作爲(wèi)升降驅(qū)動(dòng)力，液壓缸需隨升降機(jī)構(gòu)運(yùn)動(dòng)，此時(shí)液壓缸既作爲(wèi)升降時(shí)的動(dòng)力又作爲(wèi)施工作業(yè)時(shí)升降機(jī)的支撐構(gòu)件。所以液壓缸及其相連接的管路對(duì)整個(gè)安全系統(tǒng)起作主要的作用因此在設(shè)計(jì)中液壓管路盡可能使用硬管，并保證軟管的配管要求，減少因系統(tǒng)管路破裂和洩漏造成液壓系統(tǒng)失效的可能性。

因此，液壓系統(tǒng)是液壓升降機(jī)械的血液循環(huán)系統(tǒng)，液壓系統(tǒng)的完善程度和技術(shù)革新的力度對(duì)升降機(jī)和高空液壓作業(yè)設(shè)備的人機(jī)安全性十分重要，高空作業(yè)車輛升降機(jī)構(gòu)的穩(wěn)定可靠是實(shí)現(xiàn)安全作業(yè)的必要條件。
