【摘要】：高層建筑的不斷涌現(xiàn),使得高層建筑室外設(shè)備的安裝與高空維修工作隨之增多,凸顯出高層建筑室外提升機(jī)械的重要性。目前,高空提升設(shè)備普遍存在固定與安裝要求較高、靈活性差、設(shè)備體積較大、不方便攜帶、使用成本高等問題,對(duì)于一些零散作業(yè),提升任務(wù)不得不完全由人力完成,不僅勞動(dòng)強(qiáng)度大、提升效率低,而且極其不安全。據(jù)不完全統(tǒng)計(jì),我國每年因高處墜落導(dǎo)致的墜亡事件高達(dá)上千起,高處墜落更是在建筑業(yè)“三大傷害”之一,發(fā)生率最高、危險(xiǎn)性極大。針對(duì)上述問題,研究開發(fā)了一種便攜式高空作業(yè)提升設(shè)備。便攜式提升設(shè)備主要由懸掛鋼絲繩、摩擦輪、驅(qū)動(dòng)電機(jī)、傳動(dòng)機(jī)構(gòu)、控制系統(tǒng)、安全裝置和機(jī)架等組成。工作時(shí)將懸掛鋼絲繩呈“∞”型纏繞在兩摩擦輪的摩擦凹槽內(nèi),依靠二者之間的摩擦力,實(shí)現(xiàn)載重裝置的升降運(yùn)動(dòng),完成升降作業(yè)。便攜式提升設(shè)備采用鋼絲繩實(shí)現(xiàn)導(dǎo)向和懸掛功能,克服了傳統(tǒng)高層建筑室外提升設(shè)備固定安裝問題;鋼絲繩與機(jī)體的可分離性以及整機(jī)采用模塊化設(shè)計(jì),使得其最大結(jié)構(gòu)件體積小、重量輕,方便個(gè)人搬運(yùn);安全裝置保證設(shè)備發(fā)生打滑或墜落時(shí)有效制動(dòng),滿足了提升設(shè)備安全性要求。高空作業(yè)安全第一。為此,利用有限元分析軟件對(duì)關(guān)鍵零部件的強(qiáng)度進(jìn)行了分析驗(yàn)算;同時(shí)利用動(dòng)力學(xué)基本知識(shí),建立了懸掛鋼絲繩的力學(xué)模型,給出了懸掛鋼絲繩張力的時(shí)變函數(shù),利用MATLAB/Simulink模塊,進(jìn)行數(shù)據(jù)仿真,對(duì)其最大拉力進(jìn)行了安全核定,進(jìn)一步驗(yàn)證了該新型便攜式提升設(shè)備設(shè)計(jì)的合理性。
[Abstract]:With the continuous emergence of high-rise buildings, the installation and maintenance of outdoor equipment in high-rise buildings are increasing, which highlights the importance of outdoor lifting machinery in high-rise buildings. At present, high altitude lifting equipment generally has some problems such as high requirement of fixing and installation, poor flexibility, large volume of equipment, inconvenient carrying, high cost of use, etc. For some scattered operations, the lifting task has to be completed entirely by manpower. Not only the labor intensity is large, the promotion efficiency is low, and extremely unsafe. According to incomplete statistics, there are as many as thousands of falling deaths caused by high falls every year in our country, which is one of the "three major injuries" in the construction industry, with the highest incidence and great danger. In order to solve the above problems, a portable elevation lifting equipment is developed. Portable lifting equipment consists of suspension wire rope, friction wheel, drive motor, transmission mechanism, control system, safety device and frame. The suspension wire rope is wound in the friction grooves of the two friction wheels in the shape of "鈭，
