施工升降機(jī)是建筑中經(jīng)常使用的載人載貨施工機(jī)械，主要用于高層建筑的內(nèi)外裝修、橋梁、煙囪等建筑的施工。由于其獨(dú)特的箱體結(jié)構(gòu)讓施工人員乘坐起來既舒適又安全，已被公認(rèn)為高層建筑施工不可缺少的關(guān)鍵設(shè)備之一。施工升降機(jī)主要組成部分如下：導(dǎo)軌架、吊籠、傳動系統(tǒng)、附墻架、底架護(hù)欄、電氣系統(tǒng)、安全保護(hù)裝置、電纜供電裝置等。
1、施工升降機(jī)的安全開關(guān)都是根據(jù)安全需要設(shè)計(jì)的，有圍欄門限位、吊籠門限位、頂門限位、極限位開關(guān)、上下限位開關(guān)、對重防斷繩保護(hù)開關(guān)等。為了避免事故隱患的發(fā)生，使用單位領(lǐng)導(dǎo)應(yīng)該加強(qiáng)管理，嚴(yán)格要求升降機(jī)維護(hù)和操作人員定期檢查各種安全開關(guān)的安全可靠性，杜絕事故的發(fā)生。
Construction elevator safety switches are designed according to the security needs, fenced door stopper, hanging kennel limit, Dingmen limit, limit switches, upper and lower limit switches, heavy anti-broken rope protection switch. In order to avoid the occurrence of accidents, the use of unit leaders should strengthen management and strict requirements lift maintenance and operations personnel regularly check the safety and reliability of various safety switches, to prevent accidents.
2、施工升降機(jī)各停靠層應(yīng)設(shè)置?？堪踩雷o(hù)門。如果不按要求設(shè)置，在高處等候的施工人員很容易發(fā)生意外墜落事故。在設(shè)置?？堪踩雷o(hù)門時(shí)，應(yīng)保證安全防護(hù)門的高度不小于1.8m，且層門應(yīng)有聯(lián)鎖裝置，在吊籠未到停層位置，防護(hù)門無法打開，保證作業(yè)人員安全。
Each stop layer construction elevator safety door stop should be set. If you do not follow the requirements set in the height of construction workers are prone to accidents waiting to fall accident. When setting docked security doors, security doors should ensure a high degree of not less than 1.8m, and the landing door interlock device should be in the position of the cage yet reached the stop layer, protective door can not be opened, to ensure worker safety.
3、施工升降機(jī)采用變頻調(diào)速對制動器無磨損，任意低的就位速度，平層精度高；速度的平滑過渡，對機(jī)構(gòu)和結(jié)構(gòu)件無沖擊，提高了升降機(jī)的安全性；幾乎任意寬的調(diào)速范圍，提高了升降機(jī)的工作效率；節(jié)能的調(diào)速方式，減少了系統(tǒng)運(yùn)行的能耗等，正是因?yàn)檫@些明顯的特點(diǎn)和優(yōu)勢，使變升降機(jī)的安全運(yùn)行和減少運(yùn)行能耗有重要的意義。
Frequency control of construction hoist brake wear, place arbitrarily low speed, high precision leveling; smooth transition speed of institutional and structural parts without impact, improving the safety of lifts; almost any wide speed range improve the efficiency of lift; energy-saving speed, reducing the energy consumption of the system is running, etc., precisely because of these distinctive features and advantages, so that becomes the safe operation of lifts and reducing energy consumption has important significance.
