class="title">詳細(xì)說(shuō)明</p><div id="8new8qz" class="box"><p><p> 塔吊使用環(huán)境及自身結(jié)構(gòu)的危險(xiǎn)因素A.塔吊在戶外使用，自然環(huán)境條件成為安全使用的決定性因素，例如：低溫脆斷時(shí)候?qū)λ蹁摻Y(jié)構(gòu)的極大威脅，破壞既突然，有無(wú)可靠的計(jì)算方法進(jìn)行預(yù)測(cè) ，除了應(yīng)力集中和溫度的因素，溫度是導(dǎo)致脆性破壞的主要因素。B：由于塔吊要頻繁轉(zhuǎn)移，安裝，為了抵抗較大的傾覆力矩，需要堅(jiān)固的基礎(chǔ)和支撐體，因而有流動(dòng)式起重機(jī)和固定式起重機(jī)的特點(diǎn)，為了滿足較大的起升高度和幅度的要求，要解決轉(zhuǎn)移、安裝的困難會(huì)給結(jié)構(gòu)帶來(lái)許多不利的因素，例如：塔吊伸縮塔身。折疊臂架、頂升加節(jié)等，北海工程塔吊。建筑工地上臨時(shí)性又給基礎(chǔ)和支撐的設(shè)置帶來(lái)許多不利的因素，北海工程塔吊，在附著和內(nèi)爬時(shí)，支撐的強(qiáng)度和安全直接取決與正在施工的建筑物承載能力，北海工程塔吊，與建筑物密切相關(guān)，又增加了潛在的危險(xiǎn)因素。塔吊的操作方法有哪些？北海工程塔吊</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="北海工程塔吊,塔吊" src="https://tyunfile.71360.com/UploadFile/gxxfty0015/637395012948629802/613184.jpg"></div><p> 從塔機(jī)行業(yè)的發(fā)展來(lái)看，塔機(jī)行業(yè)與國(guó)民經(jīng)濟(jì)、建筑業(yè)／房地產(chǎn)業(yè)有著密切的關(guān)系。因此，從國(guó)民經(jīng)濟(jì)發(fā)展趨勢(shì)和房地產(chǎn)發(fā)展趨勢(shì)來(lái)看，對(duì)塔機(jī)行業(yè)的發(fā)展具有科學(xué)意義。2010年，中國(guó)經(jīng)濟(jì)自2009年以來(lái)持續(xù)上升，為各行各業(yè)的發(fā)展奠定了良好的基礎(chǔ)。房地產(chǎn)行業(yè)迅速回升，塔吊行業(yè)也大幅上升。進(jìn)入21世紀(jì)，我國(guó)塔機(jī)行業(yè)的整體結(jié)構(gòu)發(fā)生了巨大變化。新的企業(yè)正在進(jìn)入塔吊行業(yè)。據(jù)估計(jì)，中國(guó)有400多家塔吊制造商（其中大型企業(yè)100多家）。工凱塔機(jī)產(chǎn)品目前主要包括兩大系列，QTZ塔帽系列及QTZP平頭塔系列，噸位從60Tm到315Tm，幅度30米到75米，比較大起重量從6噸到20噸，工作覆蓋面積大，工作方式多，使用對(duì)象廣，可普遍應(yīng)用于城市中高層建筑、工業(yè)廠房、電站水壩、橋梁等各種建筑施工。北海工程塔吊塔吊應(yīng)該多久維修、保養(yǎng)？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="北海工程塔吊,塔吊" src="https://tyunfile.71360.com/UploadFile/gxxfty0015/637395012951569233/3445037.jpg"></div><p> 起重臂的構(gòu)造特點(diǎn)可分為俯仰變幅起重臂（動(dòng)臂）和小車變幅起重臂（平臂）塔式塔吊。 </p> <p> 俯仰變幅起重臂塔式塔吊是靠起重臂升降未實(shí)現(xiàn)變幅的，其優(yōu)點(diǎn)是：能充分發(fā)揮起重臂的有效高度，機(jī)構(gòu)簡(jiǎn)單，缺點(diǎn)是小幅度被限制在大幅度的30%左右，不能完全靠近塔身，變幅時(shí)負(fù)荷隨起重臂一起升降，不能帶負(fù)荷變幅。 </p> <p> 小車變幅起重臂塔式塔吊是靠水平起重臂軌道上安裝的小車行走實(shí)現(xiàn)變幅的，其優(yōu)點(diǎn)是：變幅范圍大，載重小車可駛近塔身，能帶負(fù)荷變幅，缺點(diǎn)是：起重臂受力情況復(fù)雜，對(duì)結(jié)構(gòu)要求高，且起重臂和小車必須處于建筑物上部，塔尖安裝高度比建筑物屋面要高出15-20米。 </p><p> 吊車和塔吊的區(qū)別如下： </p> <p> 1、塔吊： </p> <p> 一種塔形起重機(jī)，機(jī)身很高，可以專根據(jù)噸位大小可以無(wú)限整屬高。主要工況建房建橋梁柱煙斗等高層建筑。塔吊起重量為1噸-80噸，根據(jù)噸位大小，還有工況距離而定，為建筑起業(yè)起到了巨大的貢獻(xiàn)。 </p> <p> 塔吊分類：塔吊共分4種類型：內(nèi)爬式、**式、外附式以及中置式。 </p> <p> 2、吊車： </p> <p> 普遍用于港口、車間、工地等地的起吊搬運(yùn)機(jī)械。吊車的種類： </p> <p> A.可移動(dòng)式：汽車吊、履帶吊、行吊等。 </p> <p> B.固定式：碼頭吊、塔吊、龍門吊等。吊車這個(gè)名稱是統(tǒng)一的一個(gè)稱號(hào)。頻繁叫吊車的主要還是汽車吊、履帶吊。吊車的用處在與吊裝設(shè)備、搶險(xiǎn)、起重、機(jī)械、救援。什么是塔吊自由高度？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="北海工程塔吊,塔吊" src="https://tyunfile.71360.com/UploadFile/gxxfty0015/637395012949723756/1335711.jpg"></div><p> 我們通常所見(jiàn)的塔吊一般為附著式塔式起重機(jī)又稱自升塔式起重機(jī)專，直接固定在建筑屬物或構(gòu)筑物近旁的混凝土基礎(chǔ)上，隨著結(jié)構(gòu)的升高，不斷自行接高塔身，使起重高度不斷增大。 </p> <p> 附著式塔式起重機(jī)的自升接高目前主要是利用液壓缸頂升，采用較多的是外套架液壓缸側(cè)頂式。其頂升過(guò)程，可分為5個(gè)步驟： </p> <p> 1.將標(biāo)準(zhǔn)節(jié)吊到擺渡小車上，并將過(guò)渡節(jié)與塔身標(biāo)準(zhǔn)節(jié)相聯(lián)的螺栓松開(kāi)，準(zhǔn)備頂升。 </p> <p> 2.開(kāi)動(dòng)液壓千斤頂，將塔吊上部結(jié)構(gòu)包括頂升套架向上頂升到超過(guò)一個(gè)標(biāo)準(zhǔn)節(jié)的高度，然后用定位銷將套架固定。于是塔吊上部結(jié)構(gòu)的重量就通過(guò)定位鎖傳遞到塔身。 </p> <p> 3.液壓千斤頂回縮，形成引進(jìn)空間，此時(shí)將裝有標(biāo)準(zhǔn)節(jié)的擺渡小車開(kāi)到引進(jìn)空間內(nèi)。 </p> <p> 4.利用液壓千斤頂稍微提起標(biāo)準(zhǔn)節(jié)，推出擺渡小車，然后將標(biāo)準(zhǔn)節(jié)平衡的落在下面的塔身上，并用螺栓加以聯(lián)接。 </p> <p> 5.拔出定位銷，下降過(guò)渡節(jié)，使之與已接高的塔身聯(lián)成整體。如一次要接高若干塔身標(biāo)準(zhǔn)節(jié)，則可重復(fù)以上工序。塔吊使用環(huán)境及自身結(jié)構(gòu)的危險(xiǎn)因素有哪些？北海工程塔吊</p><p
