【摘要】：游車是石油鉆機(jī)的提升設(shè)備之一,在鉆井和修井作業(yè)中,主要用于懸吊鉆柱和處理鉆井事故,國內(nèi)外有多家生產(chǎn)廠商。常見游車結(jié)構(gòu)由上橫梁滑輪滑輪軸左側(cè)板組右側(cè)板組下提環(huán)提環(huán)銷等組成。本文完成YC450游車的結(jié)構(gòu)改進(jìn),改變了原游車側(cè)板組結(jié)構(gòu)件,取消了原設(shè)計(jì)中銷座和銷軸,將銷座功能集成到側(cè)板組中,有效解決了銷座變形等問題,改變了滑輪軸軸肩長度,降低原游車總成的4.6%,降低生產(chǎn)成本,提升了側(cè)板安全系數(shù)0.22,提升了整個(gè)系統(tǒng)的可靠性。按照API Spec 8C 2012版規(guī)范,主要對(duì)關(guān)鍵零部件進(jìn)行計(jì)算,利用UG NX5.0設(shè)計(jì)軟件建立各個(gè)零部件的三維模型,然后將各個(gè)模型導(dǎo)入到有限元環(huán)境,按照零部件的設(shè)計(jì)載荷和使用要求等工況,考慮各種載荷組合情況,對(duì)各個(gè)零部件進(jìn)行了有限元計(jì),依據(jù)有限元計(jì)算結(jié)果和理論分析結(jié)果,按照API Spec 8C 2012版中的相應(yīng)條款和設(shè)計(jì)材料指標(biāo)給出了各零部件的安全系數(shù)。目前,結(jié)構(gòu)改進(jìn)后的YC450游車已投入實(shí)際生產(chǎn),較比之前制造和維修成本降低,每年提升利潤20萬元以上。
[Abstract]:Yam is one of the lifting equipment of oil drilling rig. In drilling and workover operation, it is mainly used for suspending drill string and dealing with drilling accident. There are many manufacturers at home and abroad. Common tour car structure from the upper beam? Pulley? Pulley shaft? Left panel? Right board? Lower ring? Lift ring pin, etc. In this paper, the structure improvement of YC450 bobbin has been completed, which has changed the structure of the side plate group of the original trolley, eliminated the pin seat and pin shaft in the original design, integrated the pin seat function into the side plate group, effectively solved the deformation of the pin seat, and changed the length of the axle shoulder of the pulley shaft. The safety factor of the side plate is 0.22 and the reliability of the whole system is improved. According to the specification of API Spec 8C 2012, the key parts are calculated, and the 3D models of each component are built by using the UG NX5.0 design software, and then the models are imported into the finite element environment. According to the design load and operation requirements of the parts, considering the various load combinations, the finite element method is used to calculate the components, according to the results of the finite element calculation and the theoretical analysis. According to the corresponding terms of API Spec 8C 2012 edition and design material index, the safety factor of each part is given. At present, the improved YC450 has been put into actual production, lower than the cost of manufacturing and maintenance before, and the annual profit is increased by more than 200000 yuan.
