【摘要】：隨著長(zhǎng)大跨懸索橋在我國(guó)的迅猛發(fā)展,需要面臨如強(qiáng)風(fēng)沿海地區(qū)、山區(qū)峽谷等自然條件更加惡劣的施工環(huán)境。纜載吊機(jī)作為懸索橋加勁梁采用垂直起吊法架設(shè)安裝的專用起重設(shè)備,也必須不斷提高自身性能指標(biāo)以滿足吊裝難度不斷提高的工作環(huán)境,所以設(shè)計(jì)研究一種適應(yīng)于強(qiáng)臺(tái)風(fēng)環(huán)境、大噸位吊裝、纜上行走能力更強(qiáng)的新型纜載吊機(jī)具有重要的實(shí)際應(yīng)用價(jià)值。 以舟山大陸連島工程的特大跨海大橋-西堠門大橋鋼箱梁架設(shè)工程為研究背景,確定了適應(yīng)于強(qiáng)臺(tái)風(fēng)環(huán)境下大噸位吊裝的新型纜載吊機(jī)的主要性能指標(biāo)和技術(shù)參數(shù)�？偨Y(jié)了國(guó)內(nèi)外現(xiàn)有不同類型的纜載吊機(jī)設(shè)計(jì)方案和工作特點(diǎn),對(duì)整機(jī)各主要組成系統(tǒng)和液壓控制系統(tǒng)進(jìn)行方案設(shè)計(jì)和比選；創(chuàng)新性地設(shè)計(jì)出了能夠使新型纜載吊機(jī)實(shí)現(xiàn)纜上自行行走的行走系統(tǒng)。對(duì)新型纜載吊機(jī)在強(qiáng)臺(tái)風(fēng)環(huán)境下工作的防風(fēng)抗風(fēng)措施進(jìn)行了研究,并設(shè)計(jì)出了新型抗風(fēng)裝置,最終完成了整機(jī)的總體結(jié)構(gòu)設(shè)計(jì)。 選用三維機(jī)械設(shè)計(jì)軟件Solid workS建立新型纜載吊機(jī)的虛擬樣機(jī)模型,運(yùn)用參數(shù)化編程語(yǔ)言編程APDL在ANSYS10.0、ANSYS13.0Workbench軟件平臺(tái)上完成主要結(jié)構(gòu)件結(jié)構(gòu)計(jì)算；最后完成了整機(jī)的工程圖設(shè)計(jì)和樣機(jī)制造。 論文最后介紹并分析了新型纜載吊機(jī)風(fēng)洞試驗(yàn)和結(jié)論,完成了整機(jī)型式實(shí)驗(yàn)方案并分析了靜載實(shí)驗(yàn)結(jié)果,針對(duì)纜載吊機(jī)在西堠門大橋安裝位置的不同設(shè)計(jì)了不同的整機(jī)上纜安裝方案。 本設(shè)計(jì)以我國(guó)長(zhǎng)大跨懸索橋大噸位加勁梁在強(qiáng)臺(tái)風(fēng)環(huán)境下吊裝為設(shè)計(jì)背景,運(yùn)用虛擬樣機(jī)技術(shù)、有限元分析技術(shù)、邊界層風(fēng)洞實(shí)驗(yàn)方法,完成了能夠適應(yīng)于強(qiáng)臺(tái)風(fēng)環(huán)境、大噸位吊裝,纜上自行行走的新型纜載吊機(jī)樣機(jī)研制；對(duì)于我國(guó)如纜載吊機(jī)等懸索橋架設(shè)機(jī)械的研究和應(yīng)用有重要借鑒意義。
[Abstract]:With the rapid development of long-span suspension bridges in China, it is necessary to face the construction environment with even worse natural conditions such as strong wind coastal areas and mountain canyons. Cable crane, as a special lifting equipment for suspension bridge stiffening beam erection by vertical lifting method, must also continuously improve its own performance index to meet the increasing difficulty of hoisting work environment. Therefore, the design and research of a new type of cable crane suitable for strong typhoon environment, large tonnage hoisting and stronger walking ability on cable has important practical application value. Based on the construction of steel box girder of Xihoumen Bridge in Zhoushan continental connecting island project, the main performance indexes and technical parameters of a new type cable crane suitable for large tonnage hoisting in strong typhoon environment are determined. The design scheme and working characteristics of different types of cable crane at home and abroad are summarized. The main components and hydraulic control systems of the whole machine are designed and compared. A new type of cable crane is designed to realize self-running on the cable. The wind-proof and wind-resistant measures of the new cable crane working in strong typhoon environment are studied, and a new wind-resistant device is designed. Finally, the overall structure design of the whole machine is completed. The virtual prototype model of the new cable crane is built by using the 3D mechanical design software Solid workS, and the structure calculation of the main structural parts is completed on the ANSYS10.0 ANSYS13.0 Workbench platform by using the parametric programming language (APDL). Finally, the engineering drawing design and prototype manufacture of the whole machine are completed. At last, the paper introduces and analyzes the wind tunnel test and conclusion of the new cable crane, completes the scheme of the whole machine type experiment and analyzes the static load experiment result. According to the different installation position of cable crane in Xihoumen Bridge, different installation schemes are designed. Based on the design background of large tonnage stiffened beam of long-span suspension bridge in China under strong typhoon environment, virtual prototyping technology, finite element analysis technique and boundary layer wind tunnel experiment method are used to complete the design, which can be adapted to strong typhoon environment. The development of a new type of cable crane prototype with large tonnage hoisting and self-running on the cable is of great significance for the research and application of suspension bridge erection machinery such as cable crane in China.
